LED 15W solar street light is developing rapidly. Its main advantages are energy-saving and environmental protection, long life, no stroboscopic, no eye damage, no mosquito attraction. As long as the heat dissipation design of high-power LED solar lights is good enough, there is no problem in 50000 hours of life (the definition of life is: LED is a semiconductor component, and its chip will produce light decay due to the influence of temperature. When the light flux of LED is reduced to 30% of the initial light flux due to the light decay, the LED solar lights have no lighting significance, that is, the life is over). As a new light source, many indoor and outdoor LED solar lights are now used.

Advantages of LED 15W solar street light:

1. High light efficiency: at present, the high efficiency of a single LED solar light produced in industrial-scale can reach 140-200lm / W, and the single-sided 180 degrees LED light-emitting structure greatly improves the utilization of light. The light efficiency of the whole LED solar light is twice that of the traditional high-pressure sodium light, three times that of the fluorescent light and five times that of the incandescent light. With the progress of science, the light efficiency of LED is still improving. I believe that the light efficiency of LED will go to a higher level in the future.

2. It has a long service life. LED solar lights are made of semiconductor chips, no filament, and no glass bubble, so there is no need to worry about vibration and they are not easy to be broken so that their service life can reach 50000 hours, while the service life of ordinary incandescent lights is only 1000 hours. LED has stable performance and can work normally in the environment of - 30 ~ + 50 ° C

3. Green environmental protection, LED solar lights do not contain harmful elements such as mercury and xenon, not only will not produce electromagnetic interference but also waste can be recycled, no pollution, no ultraviolet and infrared rays, no radiation, no harm to the human body.

4. Multi Transformation: LED light source can use the principle of red, green and blue three primary colors, under the control of computer technology, make three colors have 256 levels of gray and mix randomly, and then produce 256x256x256 = 16777216 colors, forming a combination of different light colors. LED combination of light and color changes, can achieve a variety of dynamic changes and images. The color temperature of common LED solar lights is 3000-6500k, which can meet different lighting needs.

5. High color rendering index: the color rendering index of LED is very high, which usually can reach more than 70, and the specific color temperature can reach more than 80, which can meet the lighting needs of specific areas such as clothing exhibition area, museum, fresh area, etc.
