a: LEDS emit different color of light or really different frequency that to us means colors. Some LED are manufacture to provide the full spectrum of frequency. so full spectrum

Different between led infrared led?
Both are light emitting diodes, but an infrared led emits infrared light in the electromagnetic spectrum. With the naked eye, humans can't see infrared light but many cameras can. Infrared leds are used in remote controls and many other applications.
What is infrared led?
An IR LED is used in applcations like remote controls...it's much the same as as a normal Light Emitting Diode...Just that the wavelength of the emitted light is not present in the visible spectrum...
Who invented the led light bulb?
"Nick Holonyak, 75, invented the LED (light emitting diode) in the 1960s."
Why does an LED emit light when forward biased?
A special semiconductor material is used in Light Emitting Diodes (LED). When an LED is forward biased, the anode is connected to positive and cathode is connected to negative terminal of the supply, then current flows through the LED, just like in a regular diode. The electrons in the special semiconductor are excited, and when they return to 'normal' state, they give off energy in the form of photons (light rays). One such semiconductor material which is commonly used is gallium arsenide. Note: the photons are not necessarily in the visible light spectrum. The remote control for your television set or DVD player most likely has an infrared LED, to transmit information to the TV.
When a LED burns out is the light dangerous?
No, there will be no light emitted from the diode if it is burned out.
What is the difference between full spectrum and ott light?
An OttLite actually uses full spectrum lighting, so there is no difference. Full spectrum means the light simulates natural sunlight, and that covers the electromagnetic spectrum from infrared through near-ultraviolet, or all wavelengths that are useful to plant or animal life.
Can you use an incandescent light bulb in a full spectrum lamp?
no
What are the different color spectra of a LED?
A single LED emits light at one single frequency, so it has no spectrum.
What is full name of led?
hi, Full name of LED is "Light Emitting Diode"!
Where can one get Full Spectrum light bulbs?
There are many places where one can get full spectrum light bulbs. Some of these would include home improvement stores such as the Home Depot, or straight from a manufacturer such as Verilux.
Where can I purchase a full spectrum floor lamp?
You can purchase a full spectrum floor lamp online at Full Spectrum Floor lamps. They offer good prices along with explanations on their features for energy saving and light that is good for ones skin.
What is full form of led?
LED stands for light emitting diode.
What is the full from of LED?
