A light-emitting diode (LED) is a two-lead semiconductor light source. It is a pn-junction diode, which emits light when activated.  When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. ---Wikipedia

LED is known as the fourth era light source, a green light, in spite of the fact that the brilliant proficiency is a bit lower than fluorescent at present, no blaze and glowing.

As somebody says the LED can at present work after it is kept in the case for a long time, this is just very typical. A typical LED can act the length of 50,000 hours, not to mention you keep it in box. Once in a while we see some LED activity lights seem broken, truth be told,  a large portion of them are not broken but rather because of the electronic segments get broken, instead of the LED itself.

 Another advantage of LED is its quick response, which is quite important for automotive rear combination lamps, it can significantly reduce the incidence of automobile accidents, do not underestimate these several milliseconds, sometimes life-saving.
Some people say the white LED light in flashlight turns a little blue, which makes it is uncomfortable to look for a long time. This problem can be resolve by adjusting the color temperatures. When it is 2500K, the light is a little red; when it is 10000K, the light get yellow then.

LED advantages:

Contrasted and brilliant knobs and neon lights, LED is described by: working voltage is low (some just need a couple of volts); working current is little (some can sparkle with just a couple of tenths of milliamps); stun and vibration resistance is great, high dependability, long life; by changing the quality of the current through the tweak can without much of a stretch modify the power of light discharge. Because of these attributes, LED is utilized as light source as a part of some optical control gadget, and is utilized as sign show as a part of numerous electronic gadgets.

Energy-saving, environmental protection, safety, long life, low power consumption, low heat, high brightness, waterproof, miniature, shockproof, easy dimming, beam focus, easy maintenance, etc., it can be widely applied in various directions, display, decoration,small flashlights , general lighting, and other fields.

High electro-optical conversion efficiency (close to 60%), green, long life (up to 100,000 hours), low voltage (about 3V), life does not destruct with repeatedly switching, small size, low heat, high brightness, durable, easy dimming, color variety, beam focus and stability, start without delay.
