LED Bulbs Illuminating Our Lives



Although LED lights (mostly in the form of individual diodes) have been section of our daily life for some time, their use for lighting purposes started only decades later. This was due to their low light output and also to other difficulties provided only by later technical inventions.

So what are the circumstances making it easy to have LED bulbs, which operate at mains and emit enough light to replace some of our current bulbs?

Light emitting diodes operate at lv DC, therefore LED bulbs in household use have to include internal circuits to operate from AC. Another critical condition is actually a decent light output of the LEDs. Although, the sunshine emitted by a single LED is growing quickly due to the great deal of research completed in the area, most LED light bulbs contain multiple diodes, to improve light emission. LED light bulbs used as a principal supply of lighting in households began with the introduction of SMD technology to LED lighting solutions, and it was accompanied by high power LEDs. They are very bright LEDs, but they are difficult to put into the little space supplied by the traditional light bulb.

Breakthrough products in household use were Osram's replacement for a 40W conventional light last year, and Philips' replacement of a 50W bulb in May 2010. The sunshine bulbs made up of this high light output are full replacements of previous light bulbs of filament types, sticking with the same beam angles. At the same time, hundreds of Chinese manufacturers work on developing new LED products at a price far more available to the masses. These solutions might lack brandings that are a warranty for quality, but might produce quality products with warranty also provided.

Another issue was heat generated through the LEDs. LEDs are heat sensitive devices, therefore their thermal management is crucial. When placed near each other - especially with high power LEDs, which generate more heat - LEDs can easily overheat the other person, which eventually results in the failing from the device. The best way of avoiding the overheating of LEDs was that they were uncovered, although this meant they were also unprotected, which can also shorten their lifespan as a result of dust or oil depositing around the LED's surface. The best solution was the introduction of heat sinks with cooling fins into the style of the bulb itself. This gives an effective air flow and eventually releases much of the warmth generated from the LEDs.

LEDs are available in standard fittings in the interest of easy replacement, however not all LEDs run at the mains, 12V Led lamps continue to be available for running them on batteries or transformers. Transformers have to be LED compatible, since the electronic transformers most frequently used in combination with halogen lights ruin LEDs. There is no such problem with LED bulbs that are suitable for 220V or mains put simply. So those, who would like to reduce their price of lighting quickly, this is actually the solution these were searching for.
