Light-emitting diode (LED)
Light-emitting diodes (LEDs) are semiconductor devices designed to convert an incoming flow of electric energy into an outgoing flow of electromagnetic radiation having wavelengths of between about 550 nanometers (green color) to about 1300 nanometers (infrared). The light-emitting diodes are one kind of minute solid-state light source that can transform electrical energy into light energy. An LED emits a light when electrons from an N-region and holes from a P-region are moved to a PN junction section and are recoupled in a PN junction semiconductor when a forward voltage is applied. Since the energy released when the free electrons are coupled is radiated as light, the light emitted from the light-emitting diode is light in a narrow wavelength range, i.e. light of a single color such as red or blue. An LED is typically composed of a semiconductor die mounted on a header that provides mechanical support for and electrical connections to the semiconductor die, a lead frame comprising a positive lead frame portion and a negative lead frame portion, the positive lead frame portion being electrically coupled to the positive terminal and the negative lead frame portion being electrically coupled to the negative terminal, a reflector element arranged to reflect light emitted from the light-emitting diode die away from the light-emitting diode die. The semiconductor die is then encapsulated to protect it. The encapsulation is transparent or includes a transparent window to allow light generated by the semiconductor die to be emitted. The light-emitting diode has received considerable attention for its advantages such as long lifetime, small size, low heat generation, low power consumption, high response speed, monochromic lighting ability, etc. Light-emitting diodes are used in many applications, including indicator lamps, display panels, signage, solid-state lighting, medical, sensing, optical interconnects, and communications including free space and guided wave communications. Particularly, the development in high brightness LEDs has successfully facilitated the LED applications to extend from indoors to outdoors.
