Purchasing links
        When is the first purchase decay test report, this is a very important link. Tender companies will provide the different units of attenuation testing report, providing some of the company's own self and some third-party testing, the testing report although test results good, real depreciation disparity because everyone is known, then how to eye genuine knowledge?
         First of all, the inspection report is the designated agency of the semiconductor alliance. Such as Beijing electric light source quality supervision and inspection center, Shanghai electric light source quality supervision and inspection center, semiconductor 13 etc., from the light degradation of the report on the detection of these units credibility, used in road lighting high street lamp power, heat generation, detected by light attenuation illustrate two problems: qualified decay, the power to pass. If a street lamp in the laboratory can not pass, but also on the road to ensure quality?
Street lamp structure
         After a long way to test the lights, the structure is a big problem. This problem has received little attention in the industry, which is one of the main causes of decay in the actual use of street lamp.
         As we all know, the haze area is so big. It not only damage to the human body, also caused marketable light big bad, especially in the northern region, dusty, haze, use after a short period of time in outdoor, the street surface covered with dust, the thermal effect to sell at a discount greatly. This is one of the main culprits are LED lamps do not all know.
According to this situation, in the lighting design must be up and down fully. Exponentially more heat dissipation area, because there is no which street lighting management departments will be regularly cleaned radiator, in the long-term use can only rely on rain washing area increase is sufficient for a due to pollution reasons caused reduction in the effective radiating area.
Light source part
         Street lamp lumen with cask effect, nor a short board, the attenuation troubled you for so many years, there is you put the lamp radiator can be good to resolve the light decay, it is not. In the past we began to discuss the use of low power chip shell type package, high power chip not, said power chip heat dissipation is not out, not that, cob packaging heat is more concentrated, by aluminum bracket or copper stent can completely solve the problem of heat conduction.
         But decay more difficult to control, the reason is managed to solve the radiator can solve the problem of the optical attenuation of the light source, the light source package exists a big misunderstanding, cob light silica gel is too thick, the silica gel encapsulated the thinner the better, for the light emitting chip radiating surface. This is cob light attenuation of not good control of the reason.
