LED flashlight structure and manufacturing method
There are many configurations, are light cup lens LED drive circuit and a switch the main parts of the barrel, but broken up and a lot of LED there are many, there are a variety of thermal design, the drive circuit is not the same, the switch structure is also varied, and the waterproof O ring if you have time, or go to the forum you dive bar no, people have enough energy to help you organize, too much work
The principle of LED luminescence is similar. But the difference is, LED is not through the electronic transitions inside the atom to emit light, but by applying a voltage across the PN junction LED, the PN junction itself in a level form (in fact, is a series of energy), then the electrons at this level and jump to the light emitting photons.
LED flashlight is LED (LED) as a light source of a new flashlight. Because LED has the characteristics of high brightness, low power consumption, long life and small size, it is an ideal choice for portable lighting.
