Zheng Zhihua once sang such a song: "The stars light up my door, let the lost children find the way to come; the stars light up my future, warm the child's heart with a little light ̇ ̇ ,", in the past The night is coming, the street has no lighting facilities, and the light from the stars is like lighting a light, illuminating the way forward for the people who travel.
At night, all kinds of lights are lingering, and the night is not the night, and the lights are shining like the daytime. Of course, the lights here are not from the stars in the sky, but from the street lamps standing on both sides of the road.
The streetlight is now very close to us, but it rarely pays attention to it until it is suddenly filled with darkness, and everyone pays attention.
Today we are talking about street lamps and talking about the most used solar street lights around us.
When we were young, we often saw this sentence in textbooks. "Our clothes and food are inseparable from the sun, and the sun gives us light and heat." This is true, the sun has given people a lot of things, and people are constantly developing and utilizing the sun. Because of the sun, there are many solar water heaters, solar power plants, solar water pumps, solar street lights, and so on.
Solar street lights, as the name suggests, consist of solar energy and lights, and more specifically should consist of three major system components: battery board, battery, and controller. In contrast, the system composition of solar street lights is much more complicated. The main light source used for solar street lamps is LED, DC energy-saving lamps, DC gas discharge lamps and electrodeless lamps.
In the past, taking the western power resources scarce area as an example, most rural power supply users are far away from the power grid, and the residents are scattered, while the construction cost of high-voltage power transmission is 10-13 thousand yuan per kilometer, which leads to high cost of erecting power supply lines. The power supply of the power grid is mainly used to meet the living and production electricity consumption of rural residents, the most important of which is lighting, small household appliances, and agricultural irrigation. For the public facilities such as road lighting, with or without, with the maturity of solar photovoltaic power generation technology, solar photovoltaic power generation in many places is regarded as the best way to solve the problem of rural power generation.

In order to solve quality problems such as surface cutting of special wire and scratch of copper wire, and to better serve customers, the company increased investment in production equipment and purchased modern automatic wire processing machine.
Recently, we bought an automatic machine that works at the same time with the industry's leading double-end peeling, winding and soldering.The equipment has strong comprehensive function, stable quality and high efficiency, and effectively solved the processing problems of special wire such as aviation wire,teflon wire and three-layer insulation wire.The peeling size of the product can be controlled within 1~2MM, with even tin on the surface and no knife mark or scratch on the surface. The productivity is greatly improved, which makes our production capacity go to a new level.
High insulation wire, high temperature resistant wire and special wire requirements are products that our company has been proud of for many years.We have a strong mission to solve problems for our customers, and a beautiful vision of win-win cooperation.
Therefore, we have strict product testing standards and purchased advanced testing equipment.Among them, high-definition microscopes are our best weapon for detecting special wires, which we call the company's eyes.Due to the very small diameter (26awg-36awg) of the wire we produced, it is a fully automatic cutting and cutting machine. It is impossible to know whether the insulation layer of the wire is scratched or cut or not, and only under the observation of the microscope can it maintain the stability of product quality.If the insulation layer of the wire is damaged, it will not be able to withstand high pressure testing and may even be broken through on the end product.If the wire has cut mark, welding high temperature will directly cause the wire to break, if there is no break, it is also a huge hidden danger.Therefore, all of our products have been tested under the microscope and passed the inspection before being delivered to the customer.
We believe that with the guarantee of quality standards, you can surely obtain more reliable products and services, and solving your problems is our greatest achievement.
With the progress of science and technology, intelligent and technological products have been widely used in our life, and our common mobile phones and computers are indispensable tools in our daily life.You will find USB cable is very important.However, you may not know that there are many types of USB cables.Why is this? As it turns out, they each serve different functions, mainly to preserve compatibility and support new devices.
Now, we will introduce the main USB cables as follows:
(1)Description and definition
Triple insulated wire is a high-performance insulation wire, the wire has three insulation layer, the copper wire, is among the first layer is a golden brown polyamine thin film, the thickness of a few microns, but affordable 2 KV pulse high voltage, the 2nd is high insulation paint coating, the third layer is transparent nylon modified glass fiber layer, the total thickness of insulating layer is only 20-100 um, its advantage is high dielectric strength, between any two layer can withstand the safety of the ac 2000 voltage, electric current density.The advancement in order to reduce transformer weight and volume.
(2)Scope of application:
1.This standard is applicable to high-frequency high-voltage winding wire, referred to as high-frequency wire.
2.This standard stipulates the product technical requirements, inspection rules and packaging of high-frequency wires.
3.Different insulation layer material is suitable for different occasions, such as the insulation layer is ETFE fluron resistance, due to high temperature resistance and high insulation, and is widely used in high-frequency transformers, computer power supply, mobile phone charger;Insulation layer PFA&ETFE, used in communication, transformer insulated wire and magnetic components.
(3)Notes:
1. Storage and use environment.Three layers of insulated wire storage conditions is the environment temperature is 25 ~ 30 ℃, relative humidity is 5% ~ 75%, the retention period is one year.It is forbidden to store three layers of insulated wires in the environment of high temperature, high humidity, direct sunlight and dust.For three-layer insulated wires that exceed the shelf-life, the insulation breakdown voltage, withstand voltage and winding property must be re-tested before they can be used.
2. Precautions during winding.(1) three layers of insulation wire is to rely on the film to strengthen the insulation.If the film is subjected to mechanical stress or thermal stress and serious deformation, damage, umbrella safety standards can not be guaranteed.(2) transformer skeleton must not have burr, contact wire corner part to be smooth (forming chamfer).The inner diameter of the outlet nozzle shall be 2-3 times the outer diameter of the conductor.(3) cut the end of the wire is very sharp, do not close to the wire film.
3.Method of stripping the capsule.Special equipment such as three-layer insulated wire stripping machine and adjustable film stripping machine should be used to peel the film.It is characterized by melting the coating on one side and stripping on the other side, so the wire will not be damaged.If the ordinary wire stripping machine is used to remove the insulation film, the wire may be stretched thin or even broken.
4.Welding device.There are two devices for welding three layers of insulated wire.A static type soft solder groove, suitable for welding Φ 0.40 mm below the three layers of insulation.When brazing, move horizontally in the solder groove and vibrate the coil frame (as shown in the right picture) to complete the welding work in a short time.In order to prevent the film from melting due to long-time immersion in the solder groove, the method of repeating 2-3 times welding is also adopted.The other welding device is a jet solder groove with air cooling, which can weld multiple coil frames at the same time and is suitable for mass production.
(4)Parameter table
Xiamen Changjing Electronic Technology CO., LTD has an imported production line, which can produce two or three layers of insulated wire according to the requirements. The color can also be red, yellow, blue, green and other products selected by users in accordance with UL and VDE safety regulations, ROHS and REACH halogen free requirements.
Network cable is a common wire in our daily life, generally used network cable has five categories, super five categories, six categories, super six categories and seven categories of network cable. So many kinds of network cable, how should we go distinguishing? Now let us introduce the types of network cables and their differences.
1.CAT1: mainly used for voice transmission (class a standard is mainly used for telephone cables before the early 1980s). Different from data transmission, it has been eliminated by the standard.
2.CAT2: 1MHZ transmission bandwidth is used for voice transmission and data transmission with a maximum transmission rate of 4Mbps, which is commonly used in the old Token Ring using 4Mbps standard Token transfer protocol and has been eliminated by the standard.
3. CAT3: the transmission bandwidth of this cable is 16MHz, which is used for voice transmission and data transmission with the maximum transmission rate of 10Mbps. It is mainly used for 10BASE--T, and is regarded as the lowest use grade by ANSI/ tia-568.c.
4. CAT4: the transmission bandwidth of this type of cable is 20MHz, which is used for voice transmission and data transmission with the maximum transmission rate of 16Mbps. The cable is mainly used for token-based LAN and 10base-t / 100base-t, which has been eliminated by the standard.
5. CAT5: this type of cable increases the winding density and has a transmission bandwidth of 100MHz. It is used for voice transmission and data transmission with a maximum transmission rate of 100Mbps.
6. CAT5E: it has low attenuation and less crosstalk. Compared with five-class line, it increases the test requirements of near-end crosstalk power and noise.The maximum bandwidth of the superquintuple is 100MHz.
7. CAT6: the transmission bandwidth of this type of cable is 250MHz, and the comprehensive attenuation cross talk ratio (ps-acr) of the six types of cabling system at 200MHz should have a large amount of allowance, which provides twice as much bandwidth as that of the over five types.The transmission performance of the six types of cabling is much higher than that of the super five standards, which is most suitable for the application with a transmission rate of 1Gbps.One important difference between the six classes and the super five classes is that they improve the performance in crosstalk and return loss. For the new generation of full-duplex high-speed network applications, excellent return loss performance is extremely important.
8. CAT6E: super six line is an improved version of the six line, released in 2008, is also ANSI/ tia-568c.2 and ISO/IEC 11801 super six line /EA level standards specified in a twisted pair cable, mainly used in the million bit network.The transmission frequency is 500 MHz, and the maximum transmission speed can reach 10Gbps, which is greatly improved in external crosstalk and other aspects.
9.CAT7: this cable is a twisted-pair cable approved in 2002 in ISO/IEC 11801 class 7 /F standard, which is mainly used for the application and development of ten-gigabit Ethernet technology.But it is no longer a non-shielded twisted pair, but a shielded twisted pair, so it can transmit at least 600 MHz at a rate of 10 Gbps.
Xiamen Changjing Electronic Technology CO., LTD. founded in 2008, is a company specializing in the production of domestic power cable, control cable, full range of low voltage cables, computer cables, rubber sets of cables, control SYV coaxial cable, shielded cable, flame retardant, refractory and other special cable 20 categories, more than 5000 kinds of specifications, widely used in electric power, metallurgy, petroleum, chemical industry, defense, power stations, coal mining, transportation, ports, construction and other industries for many years enjoyed a high reputation in the user.
Today, electrical products more and more in our life, in order to better use electricity, to the requirement of the wire is also rising, and at the same time in order to ensure the security of home life, when decorate must choose the quality of wire and cable, although at present our country cable technology already quite mature, but for many, the product knowledge is still a stranger Let's talk a little bit about common sense cables.
Single core cable: a single conductor in an insulating layer.It's common on the BV line.B stands for category, wiring;V stands for insulation: polyvinyl chloride.It is suitable for cables and wires used in power plants, household appliances, instruments and telecommunication equipment with ac voltage up to and including 450/750v.
Rubber sheathed wire and cable: suitable for transmission and distribution of coal mining machines and high-power mobile equipment with rated voltage up to and including 6/10kv.
Shielding control cable: suitable for ac rated voltage 450/750v and below the connection of electrical instruments and automatic control system transmission line.With oil resistance, water resistance, wear resistance, acid and alkali resistance and various corrosive gases, aging resistance, non-combustion and other excellent performance, suitable for metallurgy, power, petrochemical and other industries.
Flame retardant and fire-resistant cable: refers to the cable that can extinguish itself in a limited time after the sample is burned under specified test conditions and the flame spread only within a limited range after the fire source is removed.The basic characteristics are: in the case of fire may be burned out and not be able to run, but can prevent the spread of the fire.Generally speaking, in case of a fire, the wire can be limited to the combustion in a local scope, do not produce spread, keep other various equipment, to avoid greater losses.
A variety of cables is used in industrial settings for networking, power transmission, and communication. Coaxial, data, and instrumentation cables are some of the most common designs you will find. These low-voltage cables are usually rated for 2,000 V or less to distribute power, but medium-voltage designs reaching up to 35,000 V can be used if a facility has some responsibility for its utility use.
Low-voltage cables are usually constructed with copper or aluminum conductors, in either single or multi-conductor strands, bundles or braids. They are also available in flat constructions, including Flexx-Sil, Polytetrafluoroethylene (PTFE) and molded materials. Their construction usually features shielding, tough jacketing, insulation and fillers to withstand high mechanical loads, speeds and accelerations, as well as harsh environments both indoors and outdoors. These cables supply temporary dc or ac power to generators and motors on machines like conveyors, machine tools, robotics, and other large machinery.
Industrial power and data cables must often operate in tight spaces and may even be flexing and moving on a regular basis. To prevent wear and tear caused by these severe conditions, they must have bending radii ranging anywhere from 5 to 15 times the overall cable diameter. To prevent cracking, flexible jacketing materials, such as TPE, PCV, and CPE, should be used. Flat cables are ideal for flexing and tight designs and usually have a high EMI/RFI suppression rate.
Industrial cables can be utilized in a variety of ways, from open-air installations to direct-bury and in cable carriers and conduit and more. Finally, ensure all cables in your application meet the right approvals for its place of manufacture, such as the National Electrical Code (NEC), UL, CE, RoHS, and CSA, among others.

Three Major Advances in Micro LED Display Technology in 2018
2018 is going to end, the development of Micro LED technology is undoubtedly the most eye-catching block of the LED Display Industry in 2018. Before we meet 2019, let us review the important moments of several Micro LEDs.
01/ KAIST Develops Vertical Flexible Micro LED to Promote Hair Growth
Recently, the Korea Institute of Science and Technology (KAIST) has developed a Micro LED wearable device that uses vertical Micro LEDs to successfully help mice re-grow their hair.
The device was tested on a back of a mouse that shaved hair using a flexible array of 900 vertical Micro LEDs. After 20 consecutive days of treatment, the hair growth of the mice was significantly faster than that of the untreated mice. Moreover, after treatment, the newly grown hair of the mouse is longer and the hair area is wider.
KAIST point out that, Micro LEDs do not heat up to the detriment of the human body and consume only one-thousandth of the energy per unit area compared to conventional phototherapy lasers. The research results can provide a new method for treating human hair loss.
02/ New Substrate Materials for Strengthening Micro LEDs Come Out
France's Soitec has invented a new substrate, InGaNOX, in the production of indium gallium nitride high-brightness blue LEDs, which can crystallize simultaneously on the substrate. Under the same substrate material, the three primary color Micro LEDs can be driven and controlled with the same voltage.
03/ New Innovation and Research Centers are also Bringing out Innovative Micro LED Solutions
The British company Optovate was founded in 2008 and has a long history of developing Micro/Mini LED technology. In March of this year, the company announced that it had made two breakthroughs in Micro LED. First, Optovate developed a Micro LED Display stripping transfer technology that uses an ultraviolet laser and an adjustable pattern mask to lay the Micro LED chip off the substrate and directly onto the receiving substrate. Secondly, Optovate has also developed an optical array that combines the light emitted from the Micro LED chip with the principles of refraction and reflection. This technology can control micron-level chip light output for higher efficiency. When used for LCD and OLED panel backlights, Micro LED panels, etc., it can make the application design thinner.
The Belgian Microelectronics Research Center (IMEC) has also been actively involved in the development of Micro LED panel devices, focusing on the technology of rapidly transferring Micro LED chips to substrates. Through the development of the CSM machine spring structure, the Micro LED screen chip can be transferred to different substrates, and at the same time, the chip spacing can be adjusted to increase the transfer and assembly efficiency. Peter Lemmens, general manager of Imec Taiwan, believes that applications such as headsets or smart glasses will be expected to benefit first from the development of Micro LED Screen technology.
In addition, JBD in Hong Kong has also designed a heterogeneous integration technology that can realize monochrome red, green and blue Micro LED Display array module displays. JBD in On the March of this year, we have noticed that JBD uses wafer bonding (Wafer Bonding) to make Micro LED video wall wafer-level transfer (Wafer Level Transfer) to make a monochrome Micro LED module, especially Its green-light Micro LED array module has a brightness of up to 50K nits.
Micro LEDs have miniaturized chips and huge transfer characteristics, and require different levels of wafer production and processing processes. Therefore, the demand for equipment in the industry is more different than in the past. In order to continue the development of Micro LED commercial display technology, equipment manufacturers will also They have launched their own technology to strengthen the manufacturing of Micro LED.
Two major MOCVD manufacturers(led panel), AIXTRON and Veeco, have demonstrated the advantages of their devices in high-quality epitaxial silicon wafers with high wavelength uniformity and low defect density. Among them, Veeco and ALLOS Semiconductor formed an alliance to demonstrate the reproducibility of ALLOS 200 mm silicon gallium nitride epitaxial silicon wafer technology on Veeco Propel® MOCVD reactors in November.
AIXTRON does not give much to it. Its AIX G5+C and AIX 2800-G4 TM platforms offer MOCVD solutions and can achieve high-volume production targets. The GasFoilRotation® (GFR) Planetary Reactor® technology is a hybrid solution that combines single wafer rotation and batch reactor processing. Its satellite control uses GFR to achieve temperature control and flow regulation for a single wafer. AIXTRON's research and development of Micro LED technology also won the first prize of the Micro LED forward-looking technology competition.
KEHAN focuses on quality electronic components with the new buy tester YD2511 DC Low Resistance Tester.
YD2511 DC low resistance tester is an instrument specializing in measuring low value DC resistance. It can be widely used in various coil resistances. Resistance of motor transformer windings, wire resistance of various cables, contact resistance of electrical components such as switch sockets and plugs, and metal riveting resistors.
The instrument is a four-and-a-half digital tube display with a maximum resolution of 10uΩ.
You can see 10 uΩ~1.9999KΩ is divided into five measuring ranges:
Range 1: 200mΩ:10 uΩ~199.99 mΩ
Range 2: 2Ω:100 uΩ~1.9999Ω
Range 3: 20 Ω:1mΩ~19.999Ω
Range 4: 200 Ω:10mΩ~199.99Ω
Range 5: 2KΩ:100 mΩ~1.9999 KΩ
Sorting functions:
Most commercially available LED “light modules” are constructed by connecting a number of LEDs in series orinparallel to form cluster or string configurations. In cases where these lights modules include a constant-current driver as part of the assembly, an external “constant-voltage” driver or power supply is required.
Low cost LED circuits control the current flowing through the LED with a simple resistor. This is another case where a constant-voltage power source is required. Other examples where constant voltage supplies have been employed include ads signs, traffic information signs and large screen high definition LED displays.
Constant-voltage drivers come in many different forms. They can look like a conventional power supply or they can be enclosed for moisture and environmental protection.

In order to prevent the thunder stroke surge to disturb the LED lighting normal work, a lightning surge protection of a constant current power supply / constant voltage power supply power is designed, which is composed of GDT, MOV and TVS, according to the characteristics of lightning surges. And the lightning surge generator is used to test the protection performance of the circuit.
Hence The function of the surge protector is to limit the instantaneous over voltage of the incoming power line and the signal transmission line to the voltage range that the equipment or system can withstand, or to discharge a powerful lightning current into the ground to protect the protected equipment or system from the protection. Damaged by impact.
All the non dimmable and dimmable led drivers from SMARTS are designed surge protection inside the designing solution. The withstand voltage we can do for the UL listed led driver is able to reach 2-3.75KV, and 1.5-2KV for non dimmable ac dc led power supply. Eg: the withstand voltage of our class 2 UL phase cut dimming led driver 24v 60w ( model SMT-024-060VTH) is I/P-O/P:3.75KVAC.

A light-emitting diode (LED) is a semiconductor solid-state light-emitting device, uses a solid semiconductor chip as a light-emitting material. When a forward voltage is applied to both ends, carriers in the semiconductor recombine to cause photon emission to generate light.
The material used in LEDs is essentially aluminum-gallium-arsenide (AlGaAs). In its original state, the atoms of this material are strongly bonded. Without free electrons, it is impossible to conduct electricity here.
By adding impurities (called doping), additional atoms are introduced, effectively interfering with the material balance.
We know that in order to shoot electronically from the lower orbit to a higher orbit, it is necessary to increase its energy level. Conversely, if electrons are dropped from a higher orbit to a lower orbit, it is logical to release energy during the process.
Advantages of LEDs:
1. just need low voltage driver and low current led driver
2.Can be driven by constant led driver
3.The response time is very short - only about 10 nanoseconds.
4. The device does not require any heating and warm-up time.
5. Small size and light weight.
6.Strong structure, can withstand shock and vibration.
7.LEDs have a lifespan of more than 20 years.
Power factor is a factor that measures the efficiency of electrical equipment like led constant voltage power supply. The low power factor indicates that the reactive power of the circuit for alternating magnetic field conversion is large, thereby reducing the utilization rate of the device and increasing the line power loss.
By improving the power factor, the total current in the line and the electrical components in the power supply system, such as transformers, electrical equipment, wires, etc., are reduced, thereby reducing investment costs and reducing the loss of its own power.
By ensuring the good power factor, the voltage loss in the power supply system can be reduced, the load voltage can be made more stable, and the quality of the power can be improved.
Hence Regards to providing high quality products, SMARTS has issued a series of UL listed high PFC 0.95 and high efficiency 90% dimming led driver, waterproof ip67 led driver and slim led drivers.

In order to prevent the thunder stroke surge to disturb the LED lighting normal work, a lightning surge protection of a constant current power supply / constant voltage power supply power is designed, which is composed of GDT, MOV and TVS, according to the characteristics of lightning surges. And the lightning surge generator is used to test the protection performance of the circuit.
Hence The function of the surge protector is to limit the instantaneous over voltage of the incoming power line and the signal transmission line to the voltage range that the equipment or system can withstand, or to discharge a powerful lightning current into the ground to protect the protected equipment or system from the protection. Damaged by impact.
All the non dimmable and dimmable led drivers from SMARTS are designed surge protection inside the designing solution. The withstand voltage we can do for the UL listed led driver is able to reach 2-3.75KV, and 1.5-2KV for non dimmable ac dc led power supply. Eg: the withstand voltage of our class 2 UL phase cut dimming led driver 24v 60w ( model SMT-024-060VTH) is I/P-O/P:3.75KVAC.

As we all know, the LED driverin the use process, more or less there will be some problems, but how should we deal with it If we found any defective
products within warranty?
Here, let’s interview the Engineer Mr. Steven from Smarts Electronic and talk more about the deal with the defective products within warranty?
Question: How should you do if you found any defective products within warranty?
Answer:
We give 7 years warranty for UL list non-dimmable & dimmable led driver. ,2-3 years warranty for ETL list led driver. If clients use properly, hardly any of feedback from our clients about the led drivers can not work or damaged during warranty time
If you have received feedback about defective led driver from your clients, pls. ask your engineer help us verify the things as following:
--What kind of led light they used ?? What specifications of this led light?? output power / output voltage / output current??
--Check the label and ensure the driver has the proper input voltage and wattage for the job. Pls. not install overload / overvoltage / overcurrent. That will great damage lifetime of led drivers.
--Do clients have correct connection? and if they use proper dimmer ?
--what is environment temperature when led driver working on?
Install only in dry or damp locations. Do not install in wet locations. / Install in a well-ventilated area free from explosive gases and vapors.
--How long does the led drivers working everyday? Do not let the led drivers working 24/7(24hours and a week).

For lighting designing, there are usually two options of light beams to choose when it comes to choose the right luminaire for a specific lighting project, symmetrical beam or asymmetrical beam. They are two different principles of lighting the work place.
Symmetrical beam distributes light evenly in all directions. It is recommended for large area general lighting and for visual tasks. By asymmetrical lighting, usually asymmetric reflector or lens are used to direct the light sideways from the shade across the work area. Asymmetrical luminaires are ideal for concentrating the light beam in one direction.
Each has its advantages for a certain application. Key factor of choosing asymmetrical or symmetrical beam lies in the lamp installation position and other lighting conditions.
Usually most tunnel lights, street lights are of asymmetrical lighting distribution. Floodlights have both asymmetrical and symmetrical beams. While some other architectural lighting fixtures like in-ground lights and wall washer have more symmetrical than asymmetrical beams.

Asymmetrical Light Distribution VS Symmetrical Light Distribution |
Why we need asymmetrical floodlights?
Taking floodlights for example, asymmetrical type has good advantages in theater and sports stadium lighting where glare control is essential. By adopting asymmetrical floodlights, there will be no direct eye contact with the LED light source, and they will reduce sharp shadows., this means no direct strong uncomfortable feeling by the glare for audience and athletes. Asymmetrical sports floodlights facilitate the transition from dark to light spaces in work places, with very uniform and sufficient light distribution over the work area. There won’t be shade intruding the work area.
Therefore, for gym lighting, stadium lighting, theater lighting, and car park lighting etc., asymmetrical floodlights will be powerful in application.
The following are models of multi-function floodlights that have both symmetrical and asymmetrical light beams available for different lighting applications with super high light output.
For a high quality lighting, lighting distribution is as important as luminosity required. For professional lighting solution, glare control. luminous flux, and lighting uniformity are the most important factors that we cannot ignore. Here lighting distribution shows its importance.
There are five types of light distribution Types I-V. Type I and Type V are symmetrical beam for narrow area lighting, and Type II, III & IV are asymmetrical beam mainly for outdoor parking lot, alley, or building facades lighting. To choose a proper luminaire, you need to figure out the exact shape of the area to be illuminated. For example, if it's a plaza, you'll need a very broad light distribution luminaire, while a aisle you need a narrow beam luminaire to avoid light spill. For sports lighting, an improper light distribution may require more poles to meet your lighting criteria, sometimes it may be a waste of cost. The term “distribution type” defines how far forward of the luminaire (i.e., on the street side) the effective output reaches.
For area lighting, eliminating dark spots means high uniformity of lighting. You need to calculate and draft a simulation withe IES files to see what the final lighting result will be. In this process, the type of light distribution plays a crucial role. Whatever situation you are dealing with, understanding light distribution type will ensure you to design the best lighting for the area.
Here we have a look at the five types of light distribution by IESNA as below:
|
|
Type I Light Distribution: wide and symmetrical light for luminaires located in the middle of a walkway, with the width of the pattern it creates is about equal to the luminaire's height. Suitable for sidewalks, border lighting, or narrow walkways, usually in low wattage like 30W to 60W LED lights. |
|
|
Type II Light Distribution: sightly wider light distribution for installations where the fixture is installed at the edge of a wide path, or roadway. The luminaire lights an area up to 1.5 times wider than the mounting height of the luminaire. For example, if the fixture is 5m high, it will cast light up to 7.5m wide on the area. Suitable for wide paths, and side streets. |
|
|
Type III Light Distribution: cast light about 2.75 times wider than the fixture mounting. Luminaires intend to be installed along the side of the area. For example, if luminaire mounting height is 5m high, it will cover about 13.75m wide. Suitable for roadway, and parking area. |
 |
Type IV Light Distribution: asymmetric light distribution, the fixtures will cast light 2.75 times wider than mounting height, but with a more rounded distribution pattern that pushes the light outward, with little light falling behind the fixture. For optimal forward throw light distribution, they are usually installed on walls or used to illuminate specific areas. Suitable for building exterior, and perimeters of parking area, usually for high power outdoor lighting like sports lighting outdoor floodlights. |
 |
Type V Light Distribution: omnidirectional luminaires, with light in a uniform square or circle around the fixture. Suitable for large parking areas, and spaces need high uniformity of lighting. |
