About LED

What is LED?
A light-emitting diode (LED) is a semiconductor light source.
How does LED light work?
When a light-emitting diode is forward-biased (switched on), electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the color of the light (corresponding to the energy of the photon) is determined by the energy gap of the semiconductor.

An LED lamp (or LED light bulb) is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. LED lamps offer long service life and high energy efficiency. LED lamps can be made interchangeable with other types of lamps. Assemblies of high power light-emitting diodes can be used to replace incandescent or fluorescent lamps. Some LED lamps are made with identical bases so that they are directly interchangeable with incandescent bulbs.

How "green" is LED light?
85% percent of the LED components are made of recyclable materials. They can be recycled when the LED comes to the end of its life.
Advantages and Benefits of LED light

Long Life

The life of a  LED is projected to be from 30,000 to 50,000 hours, compared to 750 to 2,000 hours for an incandescent bulb, 8,000 to 10,000 hours for a compact fluorescent and 20,000 to 30,000 hours for a linear fluorescent bulb. 

Lower Temperatures

Conventional light bulbs waste most of their energy as heat. For example, an incandescent bulb gives off 90 percent of its energy as heat, while a compact fluorescent bulb wastes 80 percent as heat. LEDs remain cool. In addition, since they contain no glass components, they are not vulnerable to vibration or breakage like conventional bulbs. 

Energy Saving

LEDs can save you up to 85% of the power usage compare to the traditional light bulbs and Halogen. You pay less to you power supplier while the power price keep climbing. You save our environment by reduce carbon emission.
