Led light bulbs definition
NettetLED: [noun] a semiconductor diode that emits light when a voltage is applied to it and that is used especially in electronic devices (as for an indicator light). An LED lamp or LED light bulb is an electric light that produces light using light-emitting diodes (LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and can be significantly more than most fluorescent lamps. The most efficient commercially available LED lamps have efficiencies of 200 lumen per watt (Lm/W). Commercial LED lamps have a lifespan many times longer than incandescent lamps.

The main reason is that LED bulbs are almost 75 % more energy-efficient than incandescent bulbs and about 25 % more efficient than fluorescent bulbs. Led bulbs also have a much longer lifespan than other bulbs, some …
NettetLumens measure how much light you are getting from a bulb. More lumens means it's a brighter light; fewer lumens means it's a dimmer light. Lumens are to light what. … The current in an LED or other diodes rises exponentially with the applied voltage (see Shockley diode equation), so a small change in voltage can cause a large change in current. Current through the LED must be regulated by an external circuit such as a constant current source to prevent damage. Since most common power supplies are (nearly) constant-voltage sources, LED fixtures must include a power converter, or at least a current-limiting resistor. In some applicatio…
NettetIf you are using a small 50-watt R20 flood bulb commonly found in track, recess, or landscape lighting, you can switch to an 8 watt LED R20 bulb. 50-watt low voltage, MR16 bulbs normally only found in track lighting can be converted to 7 watt MR 16 LED bulb; these bulbs are pushed in and generate much less heat.

NettetA light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. When current passes through an LED, the electrons recombine with holes emitting light in the process. LEDs allow the current to flow in the forward direction and blocks the current in the reverse direction.
