LED Bulbs Illuminating Our way of life



Although Led lamps (mostly as individual diodes) happen to be a part of our lifestyle for a long period, their use for lighting purposes started only decades later. This was because of the low light output and to other conditions provided only by later technical inventions.

What are the circumstances that make it possible to have LED bulbs, which operate at mains and emit enough light to switch some of our current lights?

Led lights operate at reduced voltage DC, therefore LED lights in household use have to include internal circuits to use from AC. Another necessary condition is undoubtedly a decent light output of the LEDs. Although, the lighting emitted with a single LED is increasing extremely fast due to the wide range of research carried out the sector, most LED lights contain multiple diodes, to boost light emission. LED light bulbs used as a primary supply of lighting in households began with the creation of SMD technology to LED lighting solutions, and was accompanied by high power LEDs. These are very bright LEDs, but they are difficult to put into the little space given by the original lamp.

Breakthrough products in household use were Osram's replacement for a 40W conventional light last year, and Philips' replacing of a 50W bulb in May 2010. The sunshine bulbs created with this high light output are full replacements of previous lights of filament types, sticking with the same beam angles. Concurrently, hundreds of Chinese manufacturers work with developing new LED products at a price a lot more open to everybody. These solutions might lack brandings which are a guarantee for quality, but can produce quality products with warranty also provided.

Something was heat generated through the LEDs. LEDs are heat sensitive devices, therefore their thermal management is crucial. When placed close to the other person - especially with high power LEDs, which generate more heat - LEDs can easily overheat one another, which eventually leads to the failing with the device. The simplest way of avoiding the overheating of LEDs was them to be uncovered, even though this meant these were also unprotected, which could also shorten their lifespan due to the dust or oil depositing around the LED's surface. The most effective solution was the introduction of heat sinks with cooling fins into the kind of the bulb itself. This gives a proper air flow and in the end releases most of heat generated from the LEDs.

LEDs come in standard fittings in the interest of easy replacement, however not every LEDs run on the mains, 12V LED lights are still available for running them on batteries or transformers. Transformers must be LED compatible, as the electronic transformers most frequently used in combination with halogen lights ruin LEDs. There is no such downside to LED bulbs which can be ideal for 220V or mains put simply. So those, who want to reduce their price of lighting quickly, here is the solution they were searching for.
