LED full form stands for “light emitting diode”. As per as the full form of LED, it is self explanatory to be a p-n junction diode that emits light when activated. LED lighting products produce light up to 90% more effectively in comparison to incandescent light bulbs.
LED Light Composition
Incandescence is a phenomenon in which an electric current heats a wire filament, enabling the wire to generate photons which is the fundamental energy packets of light and that is a typical lightbulb produces light. LEDs work through electroluminescence, a phenomenon in which a material’s electrical stimulation causes photon emission. The most common material used in LEDs (full form) light emitting diode is gallium arsenide, however there are various variations on this basic combination, such as aluminium gallium arsenide and aluminium gallium indium phosphide. These compounds are part of the III-V semiconductor group, which consists of elements from the periodic table’s columns III and V.
Working of LED lights
A microchip receives an electrical signal, which ignites the tiny light sources known as LEDs, resulting in visible light. The heat generated by LEDs is absorbed into a heat sink to avoid performance difficulties.
Usage of LED in lightening
LEDs are used in general lighting applications in the form of bulbs and fixtures. Despite their modest size, LEDs provide unique design opportunities. Some LED bulb solutions may have a comparable physical appearance to traditional light bulbs. LEDs can be used as a permanent light source in some LED light fixtures. There are other hybrid methods that use a fixture-specific non-traditional “bulb” or shifting light source format. LEDs provide a significant opportunity for lighting form factor innovation and may be used in a far wider range of applications than previous lighting technologies.

What makes LED different?
Other lighting kinds, such as incandescent and CFL, are substantially different from LED lighting. The following are some key distinctions:-
- LEDs produce very little heat. Incandescent bulbs, on the other hand, release 90% of their energy as heat, while CFLs release roughly 80% of their energy as heat.
- LEDs, which are about the size of a speck of pepper and can emit light in a variety of colours, are the light source. White light is occasionally created by combining red, green, and blue LEDs.
- LEDs emit light in a precise direction, eliminating the need for light-trapping reflectors and diffusers. This property makes LEDs more efficient for a variety of applications, including recessed downlights and task lighting. Light must be reflected in the desired direction with other types of lighting, and more than half of the light may never exit the fixture.
- LED lighting products have a substantially longer lifespan than traditional types of lighting. A decent LED bulb can last 3 to 5 times as long as a CFL and 30 times as long as an incandescent light.
LED: A Better Alternative
LED lighting can be found in a wide range of residential and industrial devices, and the list continues to grow year after year. LED technology has advanced at a breakneck pace, resulting in increased product availability, increased manufacturing efficiency, and cheaper prices. The following are some of the most prevalent LED product kinds:-
- Under-cabinet lighting:- LEDs are perfect for lighting confined locations such as counters for cooking and reading recipes because they are tiny and directed. Because light hue and directionality can differ, it’s crucial to evaluate products to choose the best fixture for your room.
- LED Bulbs as a Replacement:- LED lamps may now affordably and efficiently replace 40, 60, 75, and even 100 Watt incandescent bulbs, thanks to improved performance and lower prices.

- Commercial and Industrial Lighting:- LEDs are useful for many industrial applications because to their high efficiency and directed nature. Street lights, parking garage lighting, walkway and other outdoor area lighting, refrigerated case lighting, modular lighting, and task lighting are all using LEDs.
- Shock resistance :- LEDs, unlike fluorescent and incandescent lights, are solid-state components that are difficult to destroy with external shock.
- Lifetime :- LEDs have a reasonably long life expectancy. According to one assessment, the battery has a useful life of 35,000 to 50,000 hours, while the period to catastrophic breakdown could be shorter or longer. Fluorescent tubes have a lifespan of 10,000 to 25,000 hours, depending on usage conditions, while incandescent light bulbs have a lifespan of 1,000 to 2,000 hours. Several DOE demonstrations have indicated that the fundamental determinant in determining the payback period for an LED product is decreased maintenance costs from the extended lifetime, rather than energy savings.
