Solar flashlights use solar panels to charge rechargeable batteries, and when the light is sufficient, the solar panels generate current and voltage under the light to charge the battery. The battery outputs electrical energy to the load. Using high-conversion efficiency monocrystalline silicon wafers, the solar energy conversion efficiency is as high as *6%. Some people call it a longevity lamp, which means a lamp that never goes out. Solid cold light source, epoxy resin package, there is no loose part in the lamp body, there is no filament luminescence easy to burn, thermal deposition, light decay and other shortcomings, the service life can reach *0,**0 to **0,**0 hours, more than *0 times longer than the traditional light source life flashlight. Changeable LED light source can use the principle of red, green and basket three primary colors, under the control of computer technology, the three colors have **6 levels of grayscale and mix arbitrarily, you can produce **6‚¬€**6‚¬€**6=*******6 colors, forming a combination of different light colors and variations, to achieve colorful dynamic changes and various images.
