How to further improve the energy-saving effect of solar street lighting

　　 The biggest selling point of solar street lighting equipment is energy saving, but the products on the market are often limited by the product's own cost, materials and heat dissipation technology, which makes the benefit of energy saving due to the influence of light efficiency problematic. Energy saving is currently mainly reflected in the following two aspects:

　　1. Convert electrical energy into light energy to the maximum extent;

　　2. Control the light energy to the maximum extent suitable for human senses.

　　 Judging from the current problems encountered in the field of solar lighting applications, the above two points are obviously not good enough. The first is the heat treatment of solar street lights. Since there is a problem of heat dissipation of the light source, it means that the heat generation of the LED light source is considerable. We can simply analyze the LED light source problem:

　　1. When the heat generation of the LED light source is high enough to affect its heat dissipation, its temperature can be seen to be normal. What kind of material can withstand tens of thousands of hours of hot baking, of course, with such high-quality materials, and the high price will be prohibitive.

　　2. The service life is actually very simple. The heat emitted by the LED will affect the life of the LED light source itself, leading to light decay; it is precisely because the heat generated by the LED light source is large that it needs to be dissipated.

　　 There is also the problem of light perception. Why do we still feel blurred vision under high-lumen solar street lights? The specific reasons are as follows:

　　 1. Our eyes are adapted to natural light for a long time, and currently almost all LED light source lighting products are monochromatic light. Compared with our eyes, whether it is warm or white, monochromatic light can never restore the color of the object itself.

　　2. Although the monochromatic light produced by solar street lights has relatively large lumens, it does not shine far away. Therefore, when we use LED light source close to the lamp, it is particularly dazzling; far away from the lamp and the brightness is not enough; in contrast, the effect of warm colors is slightly better.
