How to solve the cooling problems of LED chip of high-power LED street light

led high bay light

With a wide range of high-power white LED applications including the led high bay light for sale, the cooling problems of LED chip of high-power white LED lights such as led high bay light for sale is urgently to solve in the actual life, high heat of LED chip is generated in a very small volume, but the heat capacity of the LED itself of led high bay light for sale and other power LED lighting is small, these heat must be conducted as soon as possible otherwise it will have a very high junction temperature. We have been a lot of improvements on the chip of COB LED flood light and other power public LED lighting to leads the heat outside of the chip, the main improvement is the use of better thermal conductivity substrate material on the LED chip structure to improve the heat dissipation of the LED chip of power LED lights particularly the COB LED flood light and other power commercial and industrial LED lighting. because Cree 's LED thermal resistance use silicon carbide as the substrate, the thermal resistance is at least twice as low as that of other companies.Even if thermal resistance can be solved from the chip to the package material, but the cooling effect is not good from the package to the PCB board, which cause that the temperature of LED chip of led high bay light for sale and other power LED light rises, the phenomenon appears luminous efficiency decreases. So, just as the Panasonic want to solve this problem, the circular, linear, surface-type white LED, and led high bay light for sale board have been designed into one since 2005 to overcome the heat problem because of the interruption emergence from the package to the PCB board.Thus, in the face of constantly improving the current situation, while how to increase the heat capacity of the chip of led high bay light for sale and other power LED lights is urgent to be overcome at this stage, in addition to the material itself, but also including the wafer and the heat resistance of the packaging material, heat resistance thermal structure, thermal structure between the packaging materials and the PCB board and the thermal structure of PCB, all of which of led high bay light for sale and other led high bay light for sale needs to be holistic considerations.

several major errors of cooling LED and coping methods

led street light

LED heat misunderstanding is mainly reflected in the following aspects:
An internal quantum efficiency is not high. led street light fixture is when the electron and hole recombination, and can not produce 100% of all photons, commonly referred to as the “current leakage” of carriers leaving the PN zone composite rate. Leakage current times the voltage that this part of the power, which is converted into heat, but this part does not account for the main component, because the internal photon efficiency is close to 90%.
2 internally generated photons emitted to the outside of the chip can not be fully converted to the final heat. This part is mainly because this is called the external quantum efficiency is currently only about 30%, most of them converted to heat up.
3 undue reliance on thermal conductivity material. Because what the high-tech materials can be used to shed heat. In fact, with ordinary aluminum heat, after several tests, the heat sink temperature is 3-5 degrees Celsius higher than the bottom of the radiator only. That is, if a true thermal conductivity can be used to especially good material, the thermal resistance in the case of zero, it can lower the temperature 3-5 degrees Celsius.
4 superstition heat pipe. Heat pipe has a very good thermal capacity, which is beyond doubt. But ultimately derived thermal heat sink through the tropical air convection away. If there is no cooling fins, heat pipes will soon reach thermal equilibrium, the temperature rise together with the heat sink. And if the increase in the heat pipe heat sink, eventually radiating fins. And the contact point fin and tube heat exposure is good but not as good in other ways. The result is a high cost, the cooling effect is not improved. However, to use the integrated heat pipe thermal LED on or useful, but reasonable to structure!
5 credulous some manufacturers nm radiation publicity material. Radiation heat LED lamps in the present case temperature of 50 degrees Celsius proportion can be ignored. The radiation coating manufacturers propaganda propaganda even as they did have a good radiation effects, radiation even reached blackbody radiation, the thermal gravity but a few percent. And the coating itself will hinder the export of heat, thus affecting the thermal convection.
LED thermal problems coping methods:
1, aluminum fins
This is the most common way of cooling, aluminum fins as part of the housing to increase the cooling area.
2, thermal plastic case
LED thermal insulation using plastic replacement heat sink aluminum production, can significantly improve the thermal radiation.
3, the air hydrodynamic
Use light shell shape, creating a convection air, which is the lowest-cost way to enhance heat dissipation.
4, liquid bulb
The use of liquid bulb packaging technology, high thermal conductivity of the transparent liquid filled bulb in the lamp body. This is in addition to reflective principle, the only use of led street light fixture chip smooth thermal conductivity, thermal technology.
The use of 5-head
In the home-based lower power LED lamps, lamp often use an internal space, the driver circuit portion or all of the heat into. Such as screw cap can be used with such a large cooling metal surface of the lamp, because the lamp is a metal electrode and the socket-contact power supply line. So part of the heat can be derived therefrom heat.
6, thermal insulation aluminum plastic alternative
Thermal insulation of aluminum alloy heat sink plastic alternatives, this LED thermal plastic insulation, while maintaining cooling capacity with aluminum flat, raise the heat radiation 4-8 times. With this heat produced by the LED heat sink materials significantly enhance the overall physical cooling effect .
7, thermal heat integration – the use of high thermal conductivity ceramic
The purpose is to reduce the heat of the lamp envelope of the operating temperature of the LED chip, the led street light fixture we used the thermal expansion coefficient and thermal conductivity of metal, thermal expansion coefficient, a large gap between the material can not be welded directly to the LED chip, so high, low thermal stress damage of the LED chip. New ceramic material with high thermal conductivity, thermal conductivity close to aluminum, the expansion factor can be adjusted to synchronize with the LED chip. This can be thermal, heat integration, reduce heat conduction intermediate links.

One: difference in packaging production and testing equipment
Rigid LED packaging production equipment including the major solid crystal, wire bonders, sealed plastic machine, color separation machine, dispenser, smart oven. Five years ago, led power automatic packaging equipment is basically dominated by foreign brands, mainly from Europe and Taiwan, China has only a small amount of semi-solid crystal, wire supply equipment. In the past five years, China 's equipment manufacturing industry led drive power production has made great progress, and now automatic solid crystal, automatic sealing plastic machine, color separation machine , automatic dispenser, smart oven, etc. are manufacturers supply, with a good price.
China's LED packaging companies in the spotlight, at the forefront of scale LEDT5 lamp packaging companies are the world's most advanced packaging equipment, which is the advantage of the decision. On the hardware level, China 's above-scale enterprises led energy saving lamp packaging is the world's most advanced. Of course, some of the higher levels of test and analysis equipment to be further equipped.
Therefore, China's packaging equipment hardware has a world-leading level, with basic and advanced packaging technology development.
Two: LED chips differences
Currently Chinese mainland enterprises led fluorescent tube, about ten or so, a late start, the scale is not big enough, the biggest light diffusion plate Enterprises annual output of about 3 billion yuan, an average annual output value of every home in 1-2 million.
This year the Chinese mainland enterprises led controller fast development, technology level soon, small and medium size chip (refer 15mil or less) has been able to basically meet the domestic demand for packaging companies, large-size chip (refer to on-chip power -type W) need to be imported, mainly from the United States and Taiwan enterprises, but only after a large-size chip LED general lighting to high-volume applications.
PS diffuser plate package device performance depends plate lights, flat grille core indicators include brightness, wavelength, failure rate, antistatic capabilities, attenuation at 50% degree. Currently panel lights package small and medium size enterprises in the majority choice of homemade chips brand, chip performance of these domestic brands and foreign brands gap smaller, backlight has a good price, and meet the needs of the vast majority of LED bulb enterprise applications.
Three: Auxiliary packaging material differences
Auxiliary packaging materials including stents, gold wire, epoxy, silicone, molding strips. Auxiliary materials is an important foundation LEDT8 lamp integrated device performance, the quality of support materials can determine the failure rate of panel light guide plate of the device, the decay rate , optical properties, and energy consumption.
Currently supporting material packaging supply chain in mainland China has been better, most of the material is capable of producing supply in the mainland. However, high-performance epoxy and silicone are mainly imported, these two materials are mainly required high temperature resistance, UV, refractive index is excellent and good expansion coefficient.
With the process of globalization, Chinese panel light diffuser plate packaging companies have been able to apply to the latest and best packaging auxiliary material in the world.
Four: package design differences
The main package slim light box with a bracket-style LED, SMD type LED and power LED three main categories.
led light guide package design, including shape design, thermal design, optical design, materials matching design, parameter design.
Acrylic light guide plate design has been relatively mature, mainly in the decay lifetime, optical matching, and other aspects of the failure rate can be further on the steps.
SMD lamps light guide is designed especially top emission type TOP SMD in constantly evolving package stent size, package design, material selection, optical design, thermal design, innovation, buy led high bay lamps has broad potential.
Lighting diffuser plate design is a new world. Due to the large size power type of chip manufacturing is still in the evolving, making the structure of power LED, optics, materials, parametric design is evolving, there have been new designs appear.
China 's LED packaging design is based in a foreign country and Taiwan have been designed on the basis of improvement and innovation. Designed to rely on good computer design tools, good testing equipment and good reliability test equipment, more need based on advanced design ideas and product savvy. Currently, China's LED packaging design level but also with foreign giants have a certain gap.
Five: packaging technology differences
led packaging technology is also a very important part. For example glue solid crystal machine control, temperature and pressure wire bonders, the oven temperature, time and temperature curves, sealed plastic bubbles and card position control, etc., are the focus of process control points. Even good chip quality, DPM match is good, excellent design, high precision equipment, if it is incorrect or process control is lax, it will ultimately affect the reliability of the LED, attenuation, optical characteristics.
With China LED packaging companies in recent years of rapid development, LED packaging technology has risen to a better level, especially in some high-end needs, such as large LED display, wide color gamut LCD backlight, China 's LED packaging companies outstanding has been able to meet their needs, advanced packaging technology produced by the LED close to the international level of similar products.
Six: LED device performance differences
Performance LED devices mainly in the following six areas:
① brightness or lumens; ② bad light; ③ failure rate; ④ light efficiency; ⑤ consistency; ⑥ Optical Distribution Characteristics
1, brightness, or lumens
2, the light fades
General studies suggest that light fades little correlation with the chip, the largest packaging materials and processes associated with the degree. The impact of bad light packaging materials are solid crystal primer, fluorescent plastic, plastic closures and other outside influence bad light packaging technology mainly baking temperature and time and materials to match each process and so on.
At present, China LED packaging technology after years of development and accumulation, has a good foundation in the bad light control with some foreign products have been unbeatable.
3, the failure rate
Failure rate and chip quality, packaging auxiliary materials, production processes, design and management level related.
LED lights fail mainly for the dead, the light fades too large, the wavelength or color drift too big. Depending on the intended use of the LED device, the failure rate have different requirements. For example, uses LED lights can 1000PPM (3000 hours ); lighting uses LED as 500PPM (3000 hours); color display uses LED as 50PPM (3000 hours).
The failure rate of the overall level of China's LED packaging companies to be improved. The good news is that a small amount of China's outstanding packaging companies fail has reached the world level.
4, light efficiency
LED luminous efficiency of 90% depending on the luminous efficiency of the chip. China LED packaging companies to improve light efficiency aspects of packaging technology also has a lot of research.
If China has made a breakthrough and production on a large tile-on-chip research and development production, will greatly contribute to improving the power efficiency of light-based package devices.
5, consistency
Consistency Consistency include LED wavelength, brightness uniformity, color temperature consistency, consistency decay.
Consistency is the former three feed through process control and screening by separation achieved. The first three levels, the Chinese LED packaging technology in line with the foreign countries.
Consistency is often difficult angle sorting out the need by optimizing the design, material mechanical precision control, strict control of the production process to achieve. For example, LED full color display uses red, green, and blue oval LED angle consistency control is very important , critically affect the color quality full color LED display, becoming a high-technology LED devices.
Attenuation consistency, and material control and process control related, including different color LED attenuation uniformity and consistency of the same color LED decay.
Consistency is an important research topic buy led high bay lamps packaging technology.
Part of the LED packaging companies in China LED technology has been consistency with international standards.
6, the optical distribution characteristics
The LED is a light emitting device. For many uses for LED applications, LED light shaped distribution is an important indicator to determine the basis of secondary optics design applications, but also directly affect the visual LED application products.
For example, LED oval lens design using LED outdoor display enables the display brightness changes when the angle changes smoothly and have a greater perspective, in line with the human visual habits. Again, led street light optical requirements, making a second optical design and optical design LED lights must match, the road to achieve the best spots and best luminous efficiency.
For design and development of computer simulation software is commonly used optical means. LED packaging companies active in China to catch up with foreign technology gap is narrowing.

Due to the high price of the passenger market, margins are relatively high, the importance of various lighting manufacturers military commander of the land, if you can stand the European lighting market, the region's master orders, product validation, technology and quality, and other fields, has been is the invincible.
From the above data is difficult to find broad prospects in the global LED lighting market It depends on the advantages of LED lights.:
1, small: LED is basically a small chip is encapsulated in epoxy, so it is very small, very light.
2, low power consumption: LED power consumption is very low, in general LED operating voltage is 2-3.6V Operating current is 0.02-0.03A That is to say:.. It consumes less than 0.1W.
3, long life: In the right current and voltage, LED life of up to 100,000 hours
4, high brightness, low heat
5, environmental protection: led street light wholesale is made from non-toxic materials, unlike fluorescent lamps containing mercury can cause pollution, while LED can also be recycled.
6, durable: LED is completely encapsulated in epoxy, which are stronger than light bulbs and fluorescent tubes Light body and no loose parts, these features make the LED can be said to be easily damaged..
However, LED lamps while there are also some disadvantages:
1, the heat problem, if the heat will significantly shorten the life of the poor.
2, the low end of the LED power-saving or lower than energy saving lamps (cold cathode tube, CCFL).
3, higher initial purchase cost.
4, due to a strong directional LED light source, LED lighting design needs to consider the special optical properties.
Even with these shortcomings, the intrinsic characteristics of LED 's decision that it is best to replace the traditional light source, it has a wide range of uses:
Originally used as instruments of LED indication light, then a variety of light-colored LED has been widely used in traffic lights and a large area of ​​the display, resulting in a good economic and social benefits. To 12 inches of red traffic lights , for example, in the United States would have long-life, low-efficiency 140-watt incandescent lamp as a light source, which produces 2000 lumens of white light. The red filter, light loss of 90%, only 200 lumens of red light. In the new design of the lamp, Lumileds company adopted the 18 red led street light wholesale sources, including circuit losses, including a total power consumption of 14 watts to produce the same light effect. LED lights are also important areas of automotive light applications. In 1987, China began installing brake light in the car, because the LED fast response (nanosecond), early and let the driver know that the trailing vehicle driving conditions, reduce the incidence of rear-end accidents. In addition, LED lights on the outdoor red, green, blue full-color display, miniature flashlight key chain and other areas have been applied.

LED high bay light and LED street light

 

led street light

First, what is LED high bay light and LED street light?LED high bay light and led street lighting Manufacturer called, mainly used for architectural lighting purposes, as well as commercial space lighting, decorative ingredients heavier, which also has a round shape side, because the general had reason to consider the heat, and therefore its appearance with the traditional flood light, there are some differences.Second, LED high bay light and LED street light features:Currently available conventional LED flood light is basically a choice of 1W high power LED (each LED components are made of PMMA with a high efficiency lens, its main function is secondary distribution of light emitted from the LED, which is the second secondary optics ), there are a few companies because cooling technology handled well, and use the power of 3W or higher LED. Suitable for large occasions cast lighting, building lighting.Spotlights what other things need to pay attention to it?1, high-purity aluminum reflector, the light beam accurately, the best reflection effect.2, symmetrical narrow-angle, wide-angle and asymmetric light distribution and other systems.3, behind the open-type lamp replacement, easy maintenance.4, with the scale plate lamps are easy to adjust illumination angle.LED high bay light and led street lighting Manufacturer by controlling the built-in microchip, in a small engineering applications, can not control use, to achieve a gradual, transition, color flashing, random flashing, alternating gradient and other dynamic effects can also be controlled . via DMX, achieve chase, scan results At present, the main application areas are about these: Single building, historical buildings exterior lighting, optical transparency in the building lighting, indoor local lighting, landscape lighting, billboard, medical facilities, cultural and other specialized lighting, bars, discos and other entertainment atmosphere lighting and so on.Third, what is LED high bay light and LED street light?LED floodlight is uniform in all directions can be a point source of illumination, and its illuminated area can be adjusted, the performance of a regular octahedron illustrated in the scene. Floodlights in effect, making them one of the most widely used light source, standard floodlights used to illuminate the entire scene. Scenario can be applied to multiple floodlights to produce good results. Floodlights are renderings of the most widely used one light source in the scene can be used multiple floodlights coordinating role in the birth of good results. From a specific point uniformly illuminated objects in all directions, using it to simulate the light bulbs and candles better and better. Floodlights can be placed anywhere in the scene. For example, the camera can be placed outside of the range, or internal objects. In the scene in the distance using many different colors floodlight is very common. The floodlights can be dark and mixed projected on the model. Floodlights illuminated area is relatively large, so the effect of floodlight illumination is very easy to predict, and this light there are many secondary uses, such as the floodlights placed in a position close to the surface, then the surface generated on a bright light.It should be noted that the floodlights can not build too much, otherwise the effect will be very plain and dull figure. So to the usual effect of the production, the more attention to appreciate the impact of lighting parameters and layout of the entire scene renderings produced by light-sensitive, multi-experience, with master lighting techniques.Fourth, the LED high bay light and led street lighting Manufacturer features:Floodlights from a specific point uniformly illuminated objects in all directions, using it to simulate the light bulbs and candles better and better. Floodlights can be placed anywhere in the scene. For example, the camera can be placed outside of the range, or internal objects . In the scene in the distance using many different colors floodlight is very common. The floodlights can be dark and mixed projected on the model. Floodlights illuminated area is relatively large, so the effect of floodlight illumination is very easy to predict, and this light there are many secondary uses, such as the floodlights placed in a position close to the surface, then the surface generated on a bright light.
