タイトルまたは説明

The basic principle of solar flashlight is that sunlight is exposed to the p-n junction of semiconductor of solar cell panel on the surface of flashlight to form new hole-electron pair/ The hole flows from the region p to the n, and the electron vice versa under p-n junction electric field, and then current is formed with the circuit connected therefore. The current is stored in the accumulator. And connect circuit to drive LED to emit light when flashlight is needed. The appearance and structure of solar flashlight are similar to those of general one, with solar cell panel usually equipped on the external handle, and some will be made for dual use (battery and solar flashlights). Its main components are solar cell panel, battery (common lithium battery), LED drive circuit and LED bulb. Features of solar flashlight: it is easy to carry and novel in structure, small in size and light in weight, with high luminance and long illumination, etc. It can be charged under the sunlight, without the need to replace the battery, which has reduced the pollution of waste batteries on the environment while saving the costs of battery purchase.
