What are LED Bulbs?

Light is an essential part of our lives. Without it, nothing is possible. Even having the blessing of eyes, one needs light and vision to see through it. Light brings the new hope everyday. Earlier, without any technology people use bonfires for light. Now, over many years technology and creative innovations have taken place. Many companies have developed many electrical appliances for best lightings. Earlier, normal tube lights, bulbs were used. Now with some new innovations companies are coming with new designs, features and better quality of lightings.

One of them is LED Bulbs.

LED stands for light emitting diode. LED lighting products produce light approximately 90% more efficiently than incandescent light bulbs. The useful life of LED lighting products is defined differently than that of other light sources, such as incandescent or compact fluorescent lighting (CFL). LEDs typically do not “burn out” or fail. Instead, they experience ‘lumen depreciation’, wherein the brightness of the LED dims slowly over time. Unlike incandescent bulbs, LED “lifetime” is established on a prediction of when the light output decreases by 30 percent.

Below are some points for that one

needs to know about LED bulbs:

• LEDs are incorporated into bulbs and fixtures for general lighting applications. Small in size, LEDs provide unique design opportunities. Some LED bulb solutions may physically resemble familiar light bulbs and better match the appearance of traditional light bulbs. Some LED light fixtures may have LEDs built in as a permanent light source.

• There are also hybrid approaches where a non-traditional “bulb” or replaceable light source format is used and specially designed for a unique fixture. LEDs offer a tremendous opportunity for innovation in lighting form factors and fit a wider breadth of applications than traditional lighting technologies.

• Nowadays, there are four major types of light bulbs: incandescent, fluorescent, light-emitting diode bulbs and outdoor solar lights. Edison patented the first incandescent light bulb, which refers to a bulb with a filament that heats up to emit light.

• Handle light bulbs carefully because they can easily break, as its breakable parts are sharp enough to puncture skin. And some light bulbs contain chemicals -- like mercury in fluorescent bulbs -- that are highly toxic to humans. When fluorescent light bulbs break, the mercury inside can escape as vapor or as fine powder-like droplets that can settle onto furniture. Whether inhaled or touched, this residue is toxic enough to cause mercury poisoning.
