What should the buyer pay attention to when purchasing LED street lamps?
Detect
The first is the light-failure detection report of LED street lamps, which is a very important link.When bidding companies will provide different unit droop test report, some companies themselves provide self-inspection, there are some third party testing, although here the test report of test results is good, there is a great disparity in actual real droop, and you know why, reason is known, So how do you know the real droop?
The test report is first recognized by the semiconductor alliance.Road lighting use street lamp power high, produces heat large, through the light failure detection two problems: the light failure is qualified, the power supply passes.
LED street lamp structure
After the LED street light failure inspection, the structure is a big problem.This issue is rarely noticed in the industry, which is one of the main causes of light failure in the actual use of street lamps.
As you all know, Beijing haze area is so big, it is not only physical harm to people, also caused the right light failure, especially in the northern region, dust, fog, in outdoor use after a short period of time, the dusty street lamp surface, its cooling effect.This is also one of the main culprits of LED street lighting.
According to this situation, the design of lamps and lanterns must be up and down.Exponentially increase the cooling area, because no street lamp management department will clean the radiator on time, in the long-term use can only rely on rain wash, is standing area amplified the effective heat dissipation area caused by pollution reduction.
Heat dissipation
LED street light failure have barrel effect, also not line, there is a short board droop bothering you for so many years, the problem here is that you do lamps and lanterns of the radiator can solve droop, no, we start to talk about in the past use low-power chips encapsulation shell type, but not a high-power chips, said chip power heat scattered not to go out, not like that, COB packaging quantity of heat more concentrated, through the aluminum or copper stent can completely solve the problem of heat conduction.
But more difficult to control light failure, the reason is the radiator to solve not can solve the problem of light source, light failure, the light source package there is a big mistake, COB light silica gel is too thick, should put silica gel encapsulation, the thinner the better facilitate chip light-emitting surface cooling, this is the reason why bad COB light droop control.
