Led, as the name suggests is a term used for Light Emitting Diode. It is a semiconductor, and it emits a regular pattern of light. The led was first developed by Oleg Viladimirovich. The led in its practical form was invented by Nick Holonyak. The blue led came in the nineties, and the white super-bright led arrived in the start of the 21st century.

The led is a magic little bulb. Its many properties, like small size, and great intensity of light per wattage, and its durability, makes it useful in a number of sectors and products. The led is mainly used in led displays and advertisements. They are also used in making led products like led scrolling signs, led panels, led boards, led multicolored boards etc. The use of leds for advertising purposes has been rising day and night. The use of white LEDs and the initiation of RGB LEDs have made the outdoor led advertising very successful.

They are also used in making led warning lights or led beacons which are fixed atop high end towers. They are used in traffic signals and railway signals. A recent use of the leds has been in making backlights of vehicles. Similarly they have started to be used in making the head beams too. The LEDs find use in trailers and trucks as warning lights, and also on motorcycles as decorators.

The led is now being used as an apparel accessory too, in the form of led necklaces, led wrist bands, and led name tags, and led belt buckles. They are used as indicators in music systems, in remote controls as infra red LEDs Leds are either diffused or water clear: they are either green, blue, red, white, or RGB. They are bright, super-bright or ultra-bright. They either come loose or they come in led strips.

Led products have become a necessity on festivities – and the led lights are extensively used on Diwali, Christmas, on birthday and marriage parties. In India, a house decorated with led lights is the one where some happy occasion is going on – especially a marriage. The extensive use of LEDs in marketplaces has even given a new phrase called LED Evenings. The LEDs are very popular with electronics hobbyists, and LED kits are quite common.

Advantages of Using LEDs


• LEDs are very small, and they produce more light per watt than filament bulbs so they are more useful
• LEDs can emit a light color of their own, whereas in conventional bulbs, the color is produced by glass shells or filters.
• The small led can emit light in one direction, and its inbuilt concave reflector and lens can emit light in one direction.
• The LEDs do not blow off during on-off cycles, so they can be used for making scrolling displays, panels etc.
• The super-bright, and ultra-bright LEDs, can be seen in the daylight, and that also outdoors, which makes feasible the led advertising. In contrast, LCD cannot be seen outdoors whereas an led can.
• The life of a led is much more than a incandescent or fluorescent bulbs. The life of a led is about 50,000 hours, and it can extend beyond that.
• The response time of led is very small so they can light on and off quickly which makes them very useful for making vehicle backlights.

The led industry is widespread, but it is mainly present in china and US. The consumption of LEDs mainly goes on in India, China, Europe, and USA. The led industry is still unorganized at retail level.

The LEDs are tomorrow’s need. You will find them everywhere. Even now you see them glittering here and there, across shops and stores. The tiny LED has come a long way. Here at LEDBAZAR, you will find a lot of information regarding the led, and related products.
