Light Emitting Diode Function Edu Svet Gob Gt Key learnings: led definition: a light emitting diode (led) is a semiconductor device that emits light when electric current flows through it. working principle of led: the working principle of led involves applying a forward bias current, which causes electrons and holes to recombine at the junction, producing light. Fig. 16.0 1: saleh, bahaa e. a., and malvin carl teich. )xqgdphqwdov ri 3krwrqlfv 2nd ed. wiley, 2007. we will focus on light emitting diodes (leds). the efficiency of leds will be determined by the radiative recombination rate. as we have seen earlier there are many other ways that electron hole pair can recombine, all these processes (r–g. In light emitting diodes ( leds ), light is produced by a solid state process called electroluminescence. under specific conditions, solid state light sources can produce coherent light, as in laser diodes. other devices such as liquid crystal devices (lcds) control externally supplied light to form display units. Light emitting diode structure. leds are p n junction devices constructed of gallium arsenide (gaas), gallium arsenide phosphide (gaasp), or gallium phosphide (gap). silicon and germanium are not suitable because those junctions produce heat and no appreciable ir or visible light. the junction in a led is forward biased and when electrons cross.

Led or light emitting diode is the most used electronic component in our daily life. it is a light source and in form of a small bulb that can be fitted inside a circuit. it is a special type of diode that converts electrical energy into light energy. unlike an incandescent bulb, it does not get hot, therefore it is an energy efficient light. Led definition: an led, or light emitting diode, is defined as a semiconductor device that emits light when electrically energized through a process called electroluminescence. how an led works: when forward biased, electrons and holes in an led recombine at the depletion layer, releasing energy as light, illustrating how an led works.
