LED Bulbs Smoking cigarettes Our way of life



Although Led lamps (mostly as individual diodes) have been section of our lifestyle for a long 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 conditions making it possible to have LED lights, which operate at mains and emit enough light to replace any one of our current bulbs?

Led lights operate at reduced voltage DC, therefore LED light bulbs in household use must include internal circuits to use from AC. Another critical condition is actually a significant light production of the LEDs. Although, the light emitted by way of a single LED is growing extremely fast due to the wide range of research carried out the field, most LED light bulbs contain multiple diodes, to increase light emission. LED bulbs utilized as a primary source of lighting in households began with the introduction of SMD technology to LED lighting solutions, and was accompanied by high power LEDs. They're very bright LEDs, but they are difficult to put into the little space given by the standard lamp.

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

Another issue was heat generated by the LEDs. LEDs are heat sensitive devices, therefore their thermal management is crucial. When placed near to the other person - particularly with high power LEDs, which generate more heat - LEDs can simply overheat one another, which eventually contributes to the failing with the device. The simplest way of avoiding the overheating of LEDs was that they were uncovered, even if this meant that they were also unprotected, which could also shorten their lifespan as a result of dust or oil depositing on the LED's surface. The very best solution was the creation of heat sinks with cooling fins in to the design of the bulb itself. This provides an effective air flow and in the end releases a lot of heat generated through the LEDs.

LEDs can be found in standard fittings in the interest of easy replacement, however not all LEDs run on the mains, 12V LED lights remain available for running them on batteries or transformers. Transformers need to be LED compatible, because the electronic transformers most frequently used in combination with halogen lights ruin LEDs. There is no such problem with LED bulbs which are ideal for 220V or mains put simply. So those, who would like to reduce their cost of lighting quickly, here is the solution they were searching for.
