LED Bulbs Illuminating Our everyday life
Although LED lights (mostly as individual diodes) are already section of our lifestyle for a long time, their use for lighting purposes started only decades later. This is because of the low light output also to other difficulties provided only by later technical inventions.

What are the conditions which make it easy to have LED bulbs, which operate at mains and emit enough light to exchange any one of our current bulbs?
Light emitting diodes operate at low voltage DC, therefore LED light bulbs in household use need to include internal circuits to operate from AC. Another necessary condition is obviously a good light production of the LEDs. Although, the sunshine emitted by way of a single LED is increasing extremely fast because of the wide range of research carried out the area, most LED light bulbs contain multiple diodes, to improve light emission. LED lights used as a principal way to obtain lighting in households began with the development of SMD technology to LED lighting solutions, and was followed by high power LEDs. They're very bright LEDs, however they are hard to put into the tiny space provided by the original bulb.
Breakthrough products in household use were Osram's replacement a 40W conventional light in '09, and Philips' replacing of a 50W bulb in May 2010. The light bulbs made up of this high light output are full replacements of previous lights of filament types, with similar beam angles. Simultaneously, countless Chinese manufacturers focus on developing new LED products at a cost a lot more open to everyone. These solutions might lack brandings that are a guarantee for quality, but might produce quality products with warranty also provided.

Something was heat generated by the LEDs. LEDs are heat sensitive devices, therefore their thermal management is vital. When placed close to each other - 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 easiest way of avoiding the overheating of LEDs was that they are uncovered, even if this meant that they were also unprotected, which can also shorten their lifespan due to the dust or oil depositing about the LED's surface. The most effective solution was the introduction of heat sinks with cooling fins in to the design of the bulb itself. This gives an effective air flow and finally releases most of heat generated by the LEDs.
LEDs can be found in standard fittings for the sake of easy replacement, however not every LEDs run at the mains, 12V LED lights continue to be available for running them on batteries or transformers. Transformers have to be LED compatible, because the electronic transformers most frequently combined with halogen lights ruin LEDs. There isn't any such trouble with LED bulbs which can be suitable for 220V or mains put simply. So those, who want to reduce their price of lighting quickly, this is actually the solution they were searching for.
