While LED lights (mostly in the design of individual diodes) were part of our daily life for years, their use for lighting up purposes started only years later. This was because of their low light production and to other circumstances provided only by later technical innovations.
So what are the situations that make it possible to have LED light bulbs, which work at mains and emit enough light to change any of our conventional light bulbs?
Light emitting diodes work at low voltage DC, hence LED light bulbs within household use, must include indoor circuits to work from AC. Another significant condition is obviously a quality light output of the LEDs. Despite the fact that, the light given off by a single LED is developing fast due to the enormous technological research, most LED light bulbs contain countless diodes, to increase light emission. LED light bulbs employed as a main source of lighting in households launched with the introduction of SMD technology to LED lighting systems, and was followed by increased power LEDs. These are very bright LEDs, but they are tough to place into the small space allowed by the traditional light bulb.
Discovery products in home use were Osram's replacement for a 40W ordinary light in 2009, and Philips' alternative of a 50W bulb in May 2010. The light bulbs made with this high light output are total replacements of previous lights of filament types, with the same beam angles. Also, hundreds of Chinese suppliers work on developing new LED products for a cost much more available to the average people. These products might lack branding, which are a guarantee for quality, but might manufacture quality products with warranty.
Another issue was heat generated by the LEDs. LEDs are heat sensitive devices, therefore their thermal management is crucial. When placed close to each other - especially with high power LEDs, which generate more heat - LEDs can easily overheat each other, which eventually leads to the failing of the device. The easiest way of avoiding the overheating of LEDs is, to allow them to be uncovered, although this would mean that, they are also unprotected, and this could also shorten their lifespan due to the dust or oil depositing on the LEDs surface. The best solution was the introduction of heat sinks with cooling fins into the design of the bulb itself. This provides a proper air circulation and eventually releases much of the heat generated by the LEDs.
LEDs come in typical fittings for the purpose of easy replacement, however not all LEDs work at the mains, 12V LED bulbs are still available for working them on batteries or transformers. Transformers should be LED compatible, as the electronic transformers most commonly with halogen lights harm LEDs. There is no such difficulty with LED lbulbs which are suited for 220V or mains. So those, who would like to reduce their cost of lighting immediately, this is the best solution they were looking for.
