Technological History of LED lights and advantage on other bulbs

LEDs may be small in size but new high-brightness models are producing a considerable amount of light. LED lighting technology offers many advantages over traditional lighting technologies like incandescent, compact fluorescent lights, CFLs, and other forms of lighting. 


Light-emitting diodes are solid-state devices that convert the electricity energy directly into light of  a single color. They employ 'cold' light generation technology where most of the energy is delivered in the visible spectrum. LED doesn't waste energy in the form of non-light producing heat.


Here we discuss some advantages of light-emitting diode lighting technology based on their importance:


Energy efficiency: LED lights use about 50% less electricity than other bulbs, resulting in substantial energy cost savings. LEDs aim to light in a specific direction, unlike conventional bulbs which emit light and heat in all directions.


LED lights are physically Small: It is very small power devices can be less than a tenth of a single mm2. This small size makes LEDs incredibly adaptable to an infinite number of lighting applications.


Durability: Without filaments, LEDs are breakage resistant and largely immune to vibrations. Traditional Bulb is usually contained in a glass or quartz exterior which can be susceptible to damage. LEDs are not used any glass, instead they are mounted on a circuit board and connected with soldered leads.


Environmentally Safe: LEDs do not have any kind of environmental issues common to bulb-like mercury vapor lights. Both of these contain mercury internal to the bulb and thus require special handling at the end of the product's useful lifespan.
