What is a LED?
DOMINANT SEMICONDUCTORS | DOMINANT SEMICONDUCTORSThe LED is a light emitting diode that is used in various display and lighting applications among others. Essentially it is a PN junction semiconductor diode that emits photons when it is forward biased. This light emitting effect of the LED is called injection electroluminescence.

DAV Electronics Frequently Asked QuestionsA light-emitting diode (LED) is a semiconductor device that uses solid-state electronics to create light. An LED light source (or diode) consists of a layer of electron rich material separated by a junction, from a layer of electron deficient material. Both sit on a semiconductor base. Power applied in the junction excites the electrons, which in turn emit photons of light. The color of the light depends on the chemical composition of the layers.Related Questions

What led to the development of children's trusts?
Children's trusts Frequently Asked Questions - Every Child M...Children's trusts are a response to Lord Laming's report of the inquiry into the death of Victoria Climbié, which highlighted the extent to which better working together and better communication are crucial. The evidence from the inquiry confirmed many of the messages from previous inquiries into similar child protection failings: the imperative to see and listen to children and respond to their needs, and to improve the quality of communication and joint working.
Related QuestionsWhat color is the light from the LED otoscope?
OtoscopesThe LED emits a full spectrum light color. This appears as a white light with a slight bluish tint. Full spectrum light is the the same spectrum of light that is emitted by sunshine. Full spectrum light will give you the most true appearance of an object viewed under it. There is a very good explanation about the advantages of full spectrum light on the OTT-LITE® website at http://www.ott-lite.com/cms/vsp.
Related QuestionsWhy are the LED's only on the Primary and Assault panels?
FAQ'sI didn't use them on the Street Fighter Panel because I was using the bi-directional inputs and didn't want them flashing when I pressed a button. I didn't include them on the Secondary and Sarge panels, because I will always use these along with a main panel and the main panel has them. They would have looked good on the Star Wars Yoke panel, but I ended up not hooking this through the I-PAC and didn't have space on the panel anyway.
Related QuestionsCan you disable the LED - because I hate LED's?
Xecuter Blaster360 - Worlds First External Xbox 360 Firmware...Yes you can. We have included an MS28 on/off switch to make it very simple. (It is essentially a power on / off switch as on the connectivity kit v2 - so you can do the 12 second trick which is documented in the tutorials section.)
Related QuestionsChildren's trusts will normally be led by the local authority - why?
Children's trusts Frequently Asked Questions - Every Child M...The Government expects that children's trusts will be led by local authorities as this is where responsibility for some key statutory duties relating to children lie. The director of children's services will be accountable for the services provided by the children's trust, and the lead member for children will be politically accountable.
Related QuestionsHow long will the LED light last before it will need replacing?
OtoscopesThe LED light source is warranted by us for life. If you left the LED light source turned on and running continuously it would burn for 25 years before it would need replacing. It would also maintain its same brightness during these 25 years of continuous use before it finally died and went black.

Technical SupportUnplug the AC power cord from the outlet. Now hold the rear panel Default button in (you'll need a pencil, paper clip or similar long slender object) and reconnect the AC power cord to the outlet. Keep holding the button in, until the Output LEDs flash the "Knight Rider" pattern (from the outside LEDs towards the center), indicating the unit has been reset. If the unit will not reset with this method contact the factory for further information.
Related QuestionsWhat is LED Emergency Lighting?
Safelincs Ltd > Fire Safety Products - Frequently Asked Ques...A:LED emergency lights use less energy than emergency lights with traditional fluorescent bulbs and contain less harmful waste. LED lights are also longer lasting than tubes. Whilst Cadmium for use in emergency lighting is currently still allowed, our range of LED emergency lighting products only uses NiMH batteries, which are more environmentally friendly. Government financial assistance is also available to switch to low energy emergency lighting and exit signs, see www.eca.gov.uk.
Related QuestionsWhy Use an LED instead of an incandescent bulb?
An incandescent bulb is highly inefficient and requires 10 times more energy than an LED. The capacitor in NightStar can only power a filament light bulb for a few seconds. By comparison, the energy stored in a battery is great enough to power inefficient devices for several hours. However, when a battery's energy is depleted, it either has to be discarded or recharged. Rechargeable batteries require external and often costly charging devices.
