wat is led lamps?

Question

glows automatically

Answer 1

Light
Emitting
Dyode

basically the small lights on machines e.g. your computer

Answer 2

LEDs are Light Emmitting Diodes. LED lamps built to replace incandescents are being used to indicate the arrival of trains at station platforms, at Traffic Signals etc. As solid-state light sources, LEDs have very long lifetimes and are generally very robust. While incandescent bulbs have an expected lifetime (to failure) of 1000 hours, LEDs are often quoted of having a lifetime of up to 100,000 hours - more than 11 years LEDs are high-efficiency light sources. White LEDs with efficacies of 25 lm/W and up are commercially available, exceeding the performance of incandescent and some fluorescent sources. The directional nature of light produced by LEDs allows the design of luminaires with higher overall efficiency.
The low power consumption of LEDs leads to significant energy savings that can often drive the installation of LED-based systems, for example traffic signals.
LEDs don't produce heat in the form of infrared radiation, which makes incandescent bulbs hot to the touch. The absence of IR radiation allows LED fixtures to be positioned in locations where heating from conventional sources would cause a particular problem e.g. illuminating food or textiles.
In many applications, LEDs are expensive compared with other light sources, when measured by metrics such as “dollars-per-lumen”. LED manufacturers continue to work towards reducing their production costs while at the same time increasing the light output of their devices. However, the high initial cost of LED-based systems is offset by lower energy consumption, lower maintenance costs and other factors.

Answer 3

Light emitting Diodes

Answer 4

LED - Light Emitting Diode

The Light emitted by this diode is brighter than normal light

Answer 5

Light Emitting Dyode ... basically if i remember correctly, instead of having a filiment that burns bright like in a LIGHT BULB , the light emitting dyode has a piece if metal or something in it that glows or emitts light when electricity passes thru or tries to pass thru it ir something. it doesn't burn like a filiment in a light buld, it just glows. they use less electricity or something and if you look them up on one of those science sites you can probably find out more about them than i can remember real quick.
I'd look it up and write more about it but it is bed time, G'night.

Answer 6

It can be a viarity of things i have an led tourch. The light when you are on your phone is led. Hope this helps

Answer 7

These are called Edison Medium Base, E27, or plain medium base light bulbs.

Answer 8

Answer 9

light emmitting diodes..they are special diode which produces light photons whenever there is enough source of electricty passing throug its chambers or PN junctions.

Answer 10

It use LEDs in place of Bulb ......... So it send "directional light "........ It uses less energy ... So it is good for energy saving ...
