solarstreetlightshopnearmeSuppliers Street lamp needs a day light, and light for a long time, if the quality is not excellent, not only the people are not satisfied, street lamp management and maintenance is also a no small task, so the street lamp requirements of its light rate is one of the key indicators. Then the following key links should be seized at the beginning of street lamp procurement. The procurement process When purchasing, the first is the light decline detection report, which is a very important link. When bidding, each company will provide different units of light decay detection reports, some provide their own self-testing, and some third-party testing. Although the test results of the test reports here are good, the actual real light decline is very large, the reason is known to everyone, so how to identify the real products? LED street lamp Test report is first recognized by the semiconductor Alliance designated agencies. Such as Beijing electric light source quality supervision and inspection center, Shanghai electric light source quality supervision and inspection center, semiconductor thirteen institute, etc., from these units of the detection report of light failure has credibility, road lighting used by the street lamp power is high, the heat generated by the light failure detection shows two problems: light failure qualified, power pass. If a street lamp can't pass the test in the lab, can it still be quality on the road? Construction of street lamp After the road light failure test, the structure is a big problem. This issue has received little attention in the industry, and is one of the main reasons for the high attenuation of street lamps when they are actually used. As we all know, the haze area of the country is so large, it not only harms people's body, but also causes the road lights to decline, especially in the northern region, dust, haze, outdoor use for a short period of time, the surface of the whole street lamp is covered with dust, its heat dissipation effect is greatly reduced. This is also LED street lights are not known as one of the main culprits. According to this situation, the lamp design must be up and down transparent. Multiply the heat dissipation area, because no street lamp management department will clean the radiator on time, in long-term use can only rely on rain washing, after the increase of the area is enough to reduce the effective heat dissipation area caused by pollution. Light source part Road lighting decline has a barrel effect, there is a short board is not good, light failure has troubled you for so many years, the problem here is that you make the lamp radiator do well can solve the light failure, not, we began to discuss the use of small power chip shell type package, but high power chip is not good, said chip power heat can not be distributed, not so, COB package heat is more concentrated, through aluminum or copper support can completely solve the thermal conductivity problem. But the light decline is more difficult to control, the reason is that the radiator must be able to solve the problem of light decline of the light source, light source packaging there is a big misunderstanding, COB light source silica gel is too thick, should be the silica gel packaging as thin as possible, to facilitate the chip light surface heat dissipation, this is the COB light source light decline is not well controlled.solarstreetlightshopnearmeSuppliers website:http://www.hp-solarlights.com/solar-street-light/
