Description

technical field [0001] The invention relates to an LED flashlight. Background technique [0002] LED flashlight is a new type of flashlight with LED (light-emitting diode) as the light source. Because LED has the characteristics of high brightness, low power consumption, long life and small size, it is an ideal choice for portable lighting. [0003] Atom electrons have many energy levels. When electrons transition from a high energy level to a low energy level, the energy of the electrons decreases, and the reduced energy is converted into photons and emitted. A large number of these photons are lasers. The LED light-emitting principle is similar, but the difference is that the LED does not emit light through the electronic transition inside the atom, but by adding a voltage to both ends of the PN junction of the LED, so that the PN junction itself Form an energy level (in fact, a series of energy levels), and then electrons jump on this energy level and generate photons to...
