1, solar street light head heat not ready; 2, although with is 1 w leds, but there are still a lot of difference. First of all, the cooling do is good, the LED light and life has great influence. If the heat emitted by leds is not dispersed in time, can cause thermal stress' When temperature changes, the object due to external constraints and internal constraints between parts, make its can't completely free expansion stress. 】 Due to the non-uniform distribution of chip light-emitting efficiency and phosphor excitation efficiency decline. When the temperature changes, the performance of the LED and encapsulation structure will be affected, which affect the reliability of the leds. So try to choose the lamp holder of cooling effect is better, do not covet is cheap to use heat the lamp holder of cut corners. Second, the influence of LED lighting' 领导( LightingEmittingDiode) That is led lighting, lighting is a solid light-emitting semiconductor devices. 】 The effect of its parameters is very much also. Such as the LED luminous flux, mild color chip size will have an impact on its glow. The same brand of chips, you use 35 mil chip that would probably be 45 mil effect is good, in addition, different brands of chips, effect also exists difference. So-called a price points a points goods. Recommended reading: the dust on the influence of the solar street light
