The lighting effect of solar street lights is related to the performance of other accessories
If there are differences in the lighting effects of solar street lights with the same output power, there are generally two situations:
1. The heat dissipation of the street lamp head is not done well;
2. Although the same 1W LED light source, there are still many differences.
First of all, the heat dissipation of the solar street light source has a great impact on the luminous efficiency and life of the LED light source. If the heat emitted by the LED cannot be dissipated in time, it will cause non-uniform distribution of thermal stress, which will cause the chip's luminous efficiency and phosphor excitation efficiency to decrease. When the temperature changes, the performance of the LED light source and the packaging structure will be affected, thereby affecting the reliability of the LED. Therefore, try to choose a lamp holder with better heat dissipation effect, and don't try to use a lamp holder that cut corners for heat dissipation.
Secondly, there are many own parameters that affect the lighting effect of solar street lights. For example, the luminous flux, color temperature and chip size of the LED will affect its luminous effect. For chips of the same brand, if you use 35mil chips, the effect is not as good as 45mil chips. In addition, chips of different brands have different effects. The so-called is that you get what you pay for.
