LED Bulbs Lighting Up Our Lives



Although Leds (mostly in the form of individual diodes) are already part of our everyday life for a long time, their use for lighting purposes started only decades later. It was because of their low light output and to other conditions provided only by later technical inventions.

So what are the stipulations making it simple to have LED lights, which operate at mains and emit enough light to exchange any of our current lights?

Light emitting diodes operate at reduced voltage DC, therefore LED lights in household use must include internal circuits to function from AC. Another necessary condition is undoubtedly a decent light production of the LEDs. Although, the light emitted by a single LED is growing very fast due to the large amount of research done in the sector, most LED lights contain multiple diodes, to boost light emission. LED light bulbs used as a principal way to obtain lighting in households began with the development of SMD technology to LED lighting solutions, and was then high power LEDs. These are very bright LEDs, however they are difficult to thrown into the tiny space supplied by the traditional light bulb.

Breakthrough products in household use were Osram's alternative to a 40W conventional light in '09, and Philips' replacing a 50W bulb in May 2010. The light bulbs created with this high light output are full replacements of previous bulbs of filament types, concentrating on the same beam angles. Concurrently, a huge selection of Chinese manufacturers work on developing new LED products at a cost far more accessible to everybody. These solutions might lack brandings which are a guarantee for quality, but will produce quality products with warranty also provided.

Something was heat generated through the LEDs. LEDs are heat sensitive devices, therefore their thermal management is vital. When placed close to each other - especially with high power LEDs, which generate more heat - LEDs can simply overheat one another, which eventually results in the failing with the device. The simplest way of avoiding the overheating of LEDs was that they are uncovered, even though this meant that these were also unprotected, and this could also shorten their lifespan because of the dust or oil depositing about the LED's surface. The most effective solution was the development of heat sinks with cooling fins into the design of the bulb itself. This allows a suitable air flow and finally releases most of heat generated from the LEDs.

LEDs can be found in standard fittings for the sake of easy replacement, however don't assume all LEDs run at the mains, 12V LED lights are still designed for running them on batteries or transformers. Transformers need to be LED compatible, since the electronic transformers most frequently combined with halogen lights ruin LEDs. There's no such problem with LED bulbs which can be suited to 220V or mains quite simply. So those, who would like to reduce their expense of lighting quickly, this is the solution these folks were looking for.
