The semiconductor light source is called LED i.e. light emitting diode. In several devices, LED is utilized as indicator lamps that are increasingly utilized for other lighting. In 1962, with the introduction of practical electronic component, the low intensity red light is emitted by LEDs however; the modern versions are accessible across the visible ultraviolet and infrared wavelengths with very high brightness.

When LED is forward and switched on then electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is known as electroluminescence and the color of the light, which is equivalent to the energy of the photon, is determined by the energy gap of semiconductor. The included optical components may be utilized to form the pattern of radiation, as LED is small in area. LED have several advantages over incandescent light sources including faster switching, lower energy consumption, improved robustness, longer lifetime, smaller size, greater durability, and reliability. For room lighting LED ...
... is powerful that are comparatively costly and it needs more exact heat management and current than compact fluorescent lamp sources of similar output.

Light emitting diode is utilized in application as different as substitute for aviation lighting automotive lighting as well as in traffic signals. The compress size, switching speed, narrow bandwidth possibility, and excessive dependability of LEDs has permitted new text and video exhibits and sensors to be developed while their high switching rates are also utilized in advanced communication technology. Infrared LED is utilized in remote control units of various commercial products, which includes television, DVD players, and other household appliances. LED have many features as they are dimmable that means they easily dimmed and the brightness of the light can be adjusted either by pulse with modulation or lowering the forward current. The Light bulb are cool in nature, i.e. as contrast to most of the light sources it produces less heat. These are small in size and light up very fast. These are used in the devices of communication and that have the faster response and long lasting impact.

LEDs are presently more costly, as it has price per lumen or an initial capital cost basis as compared to conventional lighting technologies. The extra expense partially stems from the comparatively low lumen output and the drive circuitry power supplies required. Thus, they have high initial price, which is the biggest disadvantage of light emitting diode.
