An LED Lamp is a lighting device. It can be understood to be a part of the category of solid state lighting devices. For the functioning of LED lamps, light emitting diodes are utilized, in the place of the more conventional electric filaments or gas.
LED lamps are often also referred to as LED bars or LED illuminators. LED lamps are available in the markets in a wide variety of shapes and sizes, incorporating the conventional light bulb shape as well.
It was in the 1960s that the red LED lamps became available in the markets and by the onset of the 1970s, devices making use of the LED technology became extremely popular, heralding in a new era of lighting technologies and products.
The original LED devices had a meager output which was not very useful as the power of the devices was not enough to meet the needs of a household. However, LED lamps continued to become more and more popular and fast replaced the neon lamps and lamps which ran on power supplied by indicator-like filaments.
In comparison to neon lamps, LED lamps have a longer life period and also make use of lesser amounts of voltage. Following the red LEDs, the commercial amber/yellow LED lamps as well as the orange colored LEDs were introduced. With the growing needs for differentiation, a variety of colors were introduced, such as blue and cyan and green.
It was in the 1990s that the violet colored LED lamps were finally released in the markets. Let us take a look at the technology behind the LED lamps. It is a fact that a solitary LED diode is capable of producing only a certain amount of light and also only one color of light at a particular point of time.
The mixing of colors in order to produce multiple hues is done by using more than one LED diodes in a lamp in order to be able to produce the entire spectrum of white light which contains all the colors.
The applications of LED lamps are many. They can be used in houses for the purpose of domestic lighting, in flood lights for large areas and building, as a part of the flashlights and electric torches. LEDs can also be used for stage lighting, lighting for bicycles, illuminating billboard advertisements and also in traffic lights. A popular use of LED lamps is in art galleries where they are employed to throw soft light upon the art displays and to create an effect of low heating on the pictures. There are several advantages of using LED lamps in place of conventional forms of lighting and these include high levels of efficiency and effectiveness, an increased life span, long term durability and endurance characteristics and not to forget, the small size of the diodes which allows for flexibility and change in the designing process. The challenge faced by companies in the manufacture of LED lamps is one of cost. The technology for producing white LED diodes has not been advanced significantly enough to be able to manufacture these lights on a large scale at an economically viable cost. There are also several hindrances in the process of production itself and these glitches hamper the desired large scale production and widespread distribution as envisioned by the companies.
