A light-emitting-diode (LED) (pronounced /ˌ---9.html high power ledɛliːˈdiː/),[1] is a semiconductor diode that emits light when an electric current is applied in the forward direction of the device, as in the simple LED circuit. The effect is a form of electroluminescence whereled strahler incoherent and narrow-spectrum light is led e14emitted from the p-n junction in a solid state material. led mr16 LEDs are widely used as indicator lights on electronic devices and increasingly led spotin higher power led lampenapplications such as flashlights and area lighting. An LED is usually a small area (less than 1 mm2) light source, led leuchtmittel often with optics added directly on top of the chip to shape its radiation pattern and assist in reflection.[2][3] The color of the emitted light depends on the composition and condition of the semiconducting material used, and can be infrared,led gu10 visible, or ultraviolet. Besides lighting, interesting applications include using UV-LEDs for sterilization of water andmr16 led disinfection of devices,[4] and as a grow light to enhance photosynthesis in plants.[5] ---9.html high power led led spot led mr16 led gu10 led e14 led lamp led strahler led lampen led leuchtmittel mr16 led
