The basic principle is the current from the battery out, and then reach the circuit, through the circuit to adjust the voltage and current, and then output to the light of the light, Body, lighting lighting.
Led flashlight principle is what
Atomic electrons have a lot of energy levels, and when electrons transitions from high energy levels to low energy levels, the energy of electrons is reduced, LED Flashlight and the reduced energy is converted into photon emission. A lot of these photons are laser. LED light principle is similar. But the difference is that the LED does not emit light through the electronic transitions inside the atom, LED Flashlight but by adding a voltage to both ends of the PN junction of the LED, the PN junction itself forms an energy level (in fact, a series of energy Level), LED Flashlight and then electrons jump on this level and produce photons to glow.
The new LED display parts have the advantages of low power consumption, high brightness, long life and small size. This paper starts with the development of LED display parts, discusses the LED, LED and LED for automotive applications. Development trend, LED Flashlight for the development of the display device engineers have a certain reference value.
Led flashlight what are the characteristics
1, led long life, generally up to 5 to 10 million hours or more, LED Flashlight than the traditional tungsten lamp life is 5 to 10 times higher.
2, cold light, low heat, will not damage the lamp holder, high security.
3, the reaction speed, impact resistance, good weather resistance, small size, easy small and lightweight.
4, energy saving, energy saving, low power consumption, green materials.
5, the reaction speed as long as 1us (microseconds), no warm light can improve safety.
6, low-voltage drive (voltage of 1.8 ~ 4.0V) safe.
For each person who loves outdoor adventure, the night can not flashlight, LED Flashlight especially the light led flashlight, then ultimately, high-definition LED flashlight this application.
1, the brightest, most powerful light
2, both simple and beautiful
3, a key to open
4, using the integrated flash
5, you can also use the entire screen as a light source (for all devices)
6, it is free!
