Light emitting diodes, or LEDs for short, are semiconductor devices that give off narrow spectrum light. Light emitting diodes are part of a wider class of devices called opto electronics. Opto electronics encompasses those classes of semiconductor devices in which light plays a central role, such as photodiodes, phototransistors, photomultipliers, integrated optical circuits, photoresistors, lasers, and of course, light emitting diodes.
Light emitting diodes are just like regular diodes in that they are a chip of semiconducting material with impurities added to it in order to change its electrical properties. The impurities creates a path for electrons to flow and as they do so, they give off energy in the form of light. The color of the light depends on the type of semiconducting material used in their construction. Light emitting diodes that are made of aluminium gallium arsenide gives off red and infrared light. Aluminium gallium phosphide LEDs give off green light. Aluminium gallium indium phosphide LEDs give off a very bright orange-red, orange, yellow, and green. Gallium arsenide phosphide LEDs give off red, orange-red, orange, and yellow. Gallium phosphide LEDs give off red, yellow and green. LEDs of gallium nitride give off green, emerald green, blue, and also white if aluminium is a part of the semiconductor material. Indium gallium nitride LEDs give off near ultraviolet, bluish-green, and blue. When silicon carbide, sapphire, or zinc selenide is present as a substrate of a light emitting diode, it gives off blue light. Silicon added as a substrate to LEDs is under development to be give off blue light as well. Diamond gives off ultraviolet while aluminium nitride andaluminium gallium nitride give off near to far ultraviolet. The light emitted from an LED is typically always illuminated when an electrical current is flowing through them, but flashing LEDs are also in existence.
The usage of light emitting diodes hold many advantages, especially when used in the place of incandescent bulbs. LEDs produce more light per watt than incandescent bulbs. This fact makes LEDs natural choices for battery powered devices and energy saving devices.
LEDs create the color of their light without the use of expensive and inefficient color filters, and they do not change their color tint when a dimming application is required (whereas incandescent bulb tend to turn yellow).
Light emitting diodes are the superior choice in applications where there is constant on-off cycling. Typical fluorescent bulbs will burn out quickly when constantly cycled. The life of an LED is vastly longer that fluorescent and incandescent bulbs at 100,000 to 1,000,000 hours, compared to fluorescent bulbs rated at 10,000 hours, and about 1,000-2,000 hours for incandescent bulbs. They are also less vulnerable to external damage because they are made of stronger semiconductor materials rather than the fragile materials like that of flourescent and incadescent bulbs.
Light emitting diodes achieve full brightness in fractions of a second, giving LEDs in crucial electronic devices faster response times. They are also more reliable because they fail by dimming over time rather than burning out. They are also perfect for use on printed circuit boards because of their small size.
