LED Flashlight Can Also Adjust Brightness
The basic principle of LED flashlight: The flashlight is composed of luminous body, battery, circuit, shell, reflective cup, circuit storehouse, switch and so on, the basic principle is that the current comes out from the battery, then arrives the circuit, adjusts the voltage and the electric current through the circuit, LED Flashlight then outputs to the luminous body, carries on
Eight advantages of LED flashlight
1, environmental protection lamps, protect the earth-traditional fluorescent lamps contain a lot of mercury vapor, if broken mercury vapor will evaporate into the atmosphere. But LED flashlight does not use mercury at all, and LED products are not leaded, the environment plays a protective role. LED flashlight is recognized as the 21st century green lighting.
2, efficient conversion, reduce fever-traditional lamps will produce a lot of heat, and LED lamps are to convert the electrical energy to light, will not cause waste of energy. and to the document, LED Flashlight clothing also does not produce fades the phenomenon.
3, quiet and comfortable, no noise-flashlight will not produce noise, the use of precision electronic equipment for the occasion for a good choice. Suitable for the library, office and other occasions.
4, the light is gentle, protects the eye--the traditional fluorescent lamp uses the alternating current, therefore produces 100-120 times each second the strobe. LED flashlight is the direct conversion of AC power to direct current, LED Flashlight will not produce flicker phenomenon, protect the eyes.
5, no UV, no mosquito-flashlight will not produce ultraviolet rays, so not like traditional lamps, there are many mosquitoes around the source of light. LED Flashlight The interior will become cleaner and more clean.
6, Voltage adjustable 80v-245v--traditional fluorescent lamps are released by the rectifier high voltage to light, when the voltage is reduced can not light. and LED flashlight in a certain range of voltage can be lit, but also adjust the brightness.
7, Save energy, life longer-flashlight power consumption is the traditional fluorescent lamp under One-third, life is also the traditional fluorescent lamp 1000 times times, LED Flashlight can be used for a long time without replacement, reduce labor costs. More suitable for difficult to replace the occasion.
8, strong and reliable, long-term use of--lled flashlight itself is the use of epoxy resin rather than the traditional glass, more sturdy and reliable, LED Flashlight even if smashed on the floor led will not easily damaged, can be safely used.
