LED Bulbs Lighting Up Our way of life



Although Led lamps (mostly as individual diodes) happen to be part of our daily life for a long time, their use for lighting purposes started only decades later. This is because of their low light output also to other concerns provided only by later technical inventions.

So what are the circumstances which make it possible to have LED lights, which operate at mains and emit enough light to replace any of our current lights?

Light emitting diodes operate at reduced voltage DC, therefore LED light bulbs in household use must include internal circuits to function from AC. Another necessary condition is obviously a significant light output of the LEDs. Although, the lighting emitted by way of a single LED is growing extremely fast due to the large amount of research done in the field, most LED bulbs contain multiple diodes, to boost 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 then high power LEDs. These are 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 in 2009, and Philips' replacing a 50W bulb in May 2010. The sunshine bulbs made with this high light output are full replacements of previous bulbs of filament types, sticking with the same beam angles. At the same time, countless Chinese manufacturers work on developing new LED products at a price a lot more accessible to everybody. These solutions might lack brandings which can be an assurance for quality, but can produce quality products with warranty also provided.

Something was heat generated from the LEDs. LEDs are heat sensitive devices, therefore their thermal management is crucial. When placed close to one another - especially with high power LEDs, which generate more heat - LEDs can simply 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, even though this meant that these folks were also unprotected, and this could also shorten their lifespan due to the dust or oil depositing on the LED's surface. The most effective solution was the development of heat sinks with cooling fins to the kind of the bulb itself. This provides a suitable air circulation and in the end releases a lot of the warmth generated through the LEDs.

LEDs come in standard fittings in the interest of easy replacement, however not every LEDs run at the mains, 12V Led lamps are still readily available for running them on batteries or transformers. Transformers must be LED compatible, as the electronic transformers most often used in combination with halogen lights ruin LEDs. There isn't any such problem with LED bulbs which can be ideal for 220V or mains put simply. So those, who want to reduce their cost of lighting quickly, this is the solution these folks were trying to find.
