Which ray is used in a Xerox machine?
Xerographic copiers and printers use light. Sometimes the light source is a laser, sometimes an LED, sometimes a specialized fluorescent lamp or flash lamp.
Will a infrared led kept in sunlight glow or not?
There is no such thing as and an infra-red LED. Nor will an any LED glow without a power source. That power may come from a solar cell but an LED (Light Emitting Diode) emits light it does not collect light energy.
Can led light passes through the dense smoke?
No.
What is wavelength of light emitting from LED?
It depends on the precise material used to make the LED. Different colors of LED emit different wavelengths.
Is light energy a raw material or a end product?
LED bulbs are specially designed for use in tightly sealed housings that can cause the bulb to overheat. LED bulb solution can physically resemble a familiar light bulb and may well match the appearance of a traditional light bulb. There are a number of vintage light bulbs that use LED filaments to mimic the look and feel of old - contemporary - fluorescent bulbs such as the old and modern. Use one type of LED bulbs Mid-power (SMD) LEDs, which are much lighter and more energy efficient than conventional LED luminaires. How to light an LED bulb: How does a standard LED bulb differ from an LED bulb and how does it differ from a conventional bulb? LED bulb gets hot, the heat sink at the bottom of the bulb pulls some of that heat away, but not everything. If the LED lamp is housed in a closed casing, this heat has no chance of sending it straight back into the lamps and condemning it to a slow and agonizing death. LED Retrofit Module is a bracket that can be attached to the current standard housing without replacing the old bulb hood. It includes the LED bulb base, LED light bulbs and their recessed fairing so you don't have to worry about retaining multiple parts. LED lamps are inserted by plugging their base and then into their retrofit module into the factory housing. To install LED housings and panels, you need to buy more than one component for each of your LED retrofits and LED light bulbs.
What kind of electronic has two legs and gives out light?
An LED, laser, or light bulb.
What do the acronyms 'LASER' and 'LED' stand for?
LED is "light emitting diode". LASER was originally an acronymn which meant "Light Amplification by Stimulated Emission of Radiation". Easy to see why they'd want to shorten that one.
What are the two sources of light used in Fiber Optic Cables?
laser and led
Is LED a monochromatic light?
Almost, but it has some spreading. Laser diodes are monochromatic.
Can you put a LED inside a laser housing to focus it into a beam just like a laser diode would?
No. Unless the LED is specifically a laser, you can not make it focus like a laser by putting it in a housing. A laser produces coherent light, which is why it acts like a beam. A normal LED is not coherent, and you can not make it so. Although you can not make a collimated incoherent light beam able to travel similar distances as a collimated laser beam, you can collimate incoherent light into a beam which would travel some distance with a small amount of divergence.
What is the red light of the mouse?
That would be the laser sensor of the mouse.Wireless mouse tend to have laser sensors and Optical the ones with cord. They utilizes light-emitting diodes (LED) or laser as a method of tracking movement.
Difference between light emitting diode and laser?
LEDs, known as light emitting diodes, are comprised of two lead semiconductor light sources. Laser transmitters, also known as laser diodes are comprised of an electrically charged semiconductor laser.
Where is the Hard Drive LED in a computer?
The LED is in the screen where the computer shows the light and displays on the computer when its on.
What is the difference between PIN diode and Avalanche Photo diode?
ets see the comparison of LED Diode vs LASER Diode.LED Diode :-Full form of LED- light emitting diode.-LED's are small in size, longer life, reliable and require little power.-Here generation photon by spontaneous emittion.-LED's produce a divergent and incohrent light beam.-Types of LED 1> surface emitter and 2> Edge emitter.-Their response is fast.-A wide range of wavelengths is available.-The cost of LED would be less.-An intensity of generating light is less.-Coupling efficiency of LED with fiber is less.-LED's use with the multimode fibers.-Bandwidth of led is moderate.-In led have require no extra circuit because of its simple circuit.-Here require drive current is 50 to 100mA.LASER Diode :-Full form of LASER - light emplification by stimulated emmition of radiation.-Laser's are bigger in size, longer life, less reliable and require more power then LED.-Here generating photon by stimulated emittion.-Laser produce q monochromatic and coherent light beam.-Types of Laser 1> semiconductor laser and 2> Gas laser.-Their response is faster than LED.-A small range of wavelength is available.-The cost of Laser would be higher.-Coupling efficiency of Laser with fiber is higher.-Laser use with both single mode and multi mode fibers.-Bandwidth of laser is higher.-In laser have require extra circuit for isolation of temperature reaction.-Here require drive current is Therashold current 5 to 40mA.
Why are LED lights so bright?
Its because, LED light is usually in a laser light. Lasers are ussually bright, very bright. thats all, i know might be a lie. might not--
What is the another name of laser printer?
Another name for a laser printer is an LED Printer. LED stands for Light Emitted Display. Laser Printers are more common in business than in the home, but they can work in either.
What does it mean when led light stays on aftermarket alarm?
When the LED light on an aftermarket alarm stays on, it means that the alarm is active. The light generally shows that the alarm status is "ready."
