why many of solar LED street lamp used after long time will produce light failure phenomenon, the reasons of the phenomenon of droop and where is it? Temperature is actually produce solar LED street lamp light failure phenomenon is the main reason, and a lot of solar LED street lamp in the temperature control is not perfect, because solar LED street lamp power is far greater than in normal life household lamps and lanterns, so solar street lamps manufacturer in terms of heat dissipation template must strengthen research and development and upgrade, not only that, after the completion of the assembly for heat dissipation templates must carry on the protection of the lacquer that bake, in order to prevent the corrosion of wind and rain on the climate.
LED belongs to the small scale of concentrated heat, thermal energy application in high power lamps, power input power is big also, LED the interface temperature is quite high, under the street light long time continuous work, such as the heat dissipation module not effective heat dissipation, can affect the service life of the LED and light, like the current solar LED street lamp light failure is caused by these factors. Solar LED street lamp is used outdoors, interference factors with environmental climate, so most of the manufacturers is the anodizing solar LED street lamp radiator shell to protect, or spray paint, in order to avoid the erosion of acid and alkali substances.
anodization of life is not long, and time is a bit long or oxidation discoloration, if you want to remove the heavy industry, not only time-consuming and labor will increase maintenance costs; Paint protection cost is low, the effect of protection, but generally no cooling function of the lacquer that bake, paint body itself will form the blocking effect, and then increase the thermal impedance of solar LED street lamp radiator, not only did not help, but because the heat sealed inside the radiator, LED power reduction, and finally leads to serious droop.
the above introduction is LED solar street light industry had problems, but why can't a lot of solar street lamps factory by public engineering procurement unit audit acceptance,
