Description
Technical field:
The utility model relates to a kind of LED street lamp optoelectronic integration die set.
Background technology:
Along with a large amount of utilizations of new material, new technology and improving constantly of processing technology level, the luminous efficiency of large power white light LED promotes rapidly, is used widely in the function lighting field, plays the part of more and more important role in " green illumination ".But the LED illumination is the comprehensive problem that collection microelectronics, optics, heat radiation, frame for movement, a system are controlled in one, needs upper, middle and lower combining closely of industrial chain of trip could really give play to the illumination advantage of LED.
LED light fixture product energy-conserving and environment-protective characteristic is admitted by most people at present.Section is sharp, the international well-known led chip such as Ou Silang, lumen, Seoul semiconductor producer luminous efficiency volume production level has all reached more than the 105lm/W, special U.S. Creat Company volume production level reaches 130lm/W, shows that in the development in laboratory data of its up-to-date announcement the highest light efficiency has reached 208lm/W.Believe the research and development strength with these offshore companies, volume production also is matter of time.The light efficiency of production domesticization led chip batch production is between 80-90Lm/W, but growth momentum is swift and violent, believes the technological layer that can reach very soon 100lm/W.
China's illuminating power consumption approximately has 1/3 to come from road lighting, and the road lighting industry has also accounted for very great share in whole Lighting Industry, and the energy-conservation of road lighting seems particularly urgent.Develop high efficiency smart LED street lamp extremely urgent." ten thousand in ten cities " semiconductor lighting pilot and demonstration projects that the Department of Science and Technology proposes also are in order to promote the development of domestic semiconductor lighting industry, to promote the raising of homemade chip, package level, promoting large power white light LED industrialization technology and scale production process.
The advantage of LED street lamp mainly contains 1, characteristic---the one-way of light of LED street lamp itself, does not have diffusion of light, guarantees light efficiency.2, the LED street lamp has unique secondary optical design, the illumination of LED street lamp is mapped to the zone of required illumination, has further improved light efficiency, to reach energy-conservation purpose.3, the source efficiency of LED has reached 110-130lm/W at present, and also has very large development space, and theoretical value reaches 250lm/W.And the luminous efficiency of high-pressure mercury lamp is just to increase to some extent with increased power, and therefore, the overall light efficiency LED street lamp is stronger than high-pressure mercury lamp.4, the light colour rendering of LED street lamp is more much higher than high-pressure mercury lamp, the high-pressure mercury lamp colour rendering index only has about 23, and LED street lamp colour rendering index reaches more than 75, considers from the visual psychology angle, reach equal brightness, the illuminance of LED street lamp on average can reduce more than 20% than high-pressure mercury lamp.5, light decay is little, and the light decay in 1 year uses still not reach the road occupation illumination requirement in 10 years less than 3%, and high-pressure mercury lamp, light decay are large, have descended about 1 year more than 30%, and therefore, the LED street lamp can be lower than high-pressure mercury lamp in the design of using power.6, the LED street lamp has automatic control energy-saving device, can realize saving electric energy at the reduction power that satisfies maximum possible in the different period lighting requirement situations.Can realize the computer light modulation, time segment control, light control, temperature control, Long-distance Control, the hommization functions such as automatic detecting.7, LED is low-voltage device, the voltage that drives single LEDs is safe voltage, series of products list LEDs power all is 1 watt, so it be one than using the safer power supply of high voltage source, be specially adapted to public place (such as street lighting, factories and miness illumination, automotive lighting, domestic lighting etc.).8, each unit LEDs small pieces only has very small size, thus can be prepared into the device of various shapes, and be suitable for variable environment.9, the life-span is long: can use more than 50,000 hours, weak point is exactly to can not be guaranteed in life-span of power supply.10, light efficiency is high: the chip that employing 〉=100LM is above, and can be energy-conservation more than 75% with respect to the conventional high-tension sodium vapor lamp.11, simple installation: need not to add and bury cable and need not rectifier etc., directly road lamp cap is installed on that lamp stand connects or with the nested original lamp housing of light source.12, LED does not contain harmful mercury metal, environment is worked the mischief when scrapping unlike high-pressure mercury lamp or metal halide lamp.
China recent years is rapid in the market development of LED street lamp application, becomes the country of global LED street lamp demand maximum.But domestic enterprise is also having certain gap with foreign level aspect the core technologies such as chip development processing procedure, chip package.International a lot of well-known manufacturers set up research and development centre etc. one after another to factory of the middle Office of the State Council, enlarge the influence power in China.
Existing high-power LED street lamp usually adopts a high power constant-current source to drive tens configuration modes to a hundreds of high-power LED light source, if the partial LED light source is damaged and will changes whole LED lamp holder like this, has both wasted material and has also wasted maintenance cost.More advanced LED street lamp adopts the light source modularity to process, the Lights section is divided into a plurality of modules, adopt the simultaneously principle of a plurality of modules of parallel drive of a large power supply, if the individual light source module damage only needs to change separately the light source module and gets final product, still to change whole LED lamp holder if such configuration power supply breaks down, fundamentally not solve product and safeguarding the problem that causes.
