LED light background:

LED(the light emitting diode), one full-new technical lighting source .It will be one of the most potential technical revolution all over the world, subject to energy saving, environmental friendly, light constant, high lighting control etc . And also the new technology revolution of replacement of incandescent has worked slowly.

With the application of LED in lighting industry, the high-tech, green

Lighting industry revolution will walk to around us like storm. At last , LED will be the only one choice for saving energy, some people say.


                     Reduces energy costs — uses at least 75% less energy than incandescent lighting, saving on operating expenses.

                     Reduces maintenance costs — lasts 35 to 50 times longer than incandescent lighting and about 2 to 5 times longer than fluorescent lighting. No bulb-replacements, no ladders, no ongoing disposal program.

                     Reduces cooling costs — LEDs produce very little heat.

                     Is guaranteed — comes with a minimum three-year warranty — far beyond the industry standard.

                     Offers convenient features — available with dimming on some indoor models and automatic daylight shut-off and motion sensors on some outdoor models.

                     Is durable — won’t break like a bulb.



The operational life of current white LED lamps is 100,000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. The long operational life of an led lamp is a stark contrast to the average life of an incandescent bulb, which is approximately 5000 hours. If the lighting device needs to be embedded into a very inaccessible place, using LEDs would virtually eliminate the need for routine bulb replacement.

There is no comparison between the cost of LED lights vs. traditional incandescent options. With incandescent bulbs, the true cost of the bulb is the cost of replacement bulbs and the labor expense and time needed to replace them. These are significant factors, especially where there are a large number of installed bulbs. For office buildings and skyscrapers, maintenance costs to replace bulbs can be enormous. These issues can all be virtually eliminated with the LED option.

The key strength of LED lighting is reduced power consumption. When designed properly, an LED circuit will approach 80% efficiency, which means 80% of the electrical energy is converted to light energy. The remaining 20% is lost as heat energy. Compare that with incandescent bulbs which operate at about 20% efficiency (80% of the electrical energy is lost as heat). In real money terms, if a 100 Watt incandescent bulb is used for 1 year, with an electrical cost of 10 cents/kilowatt hour, $88 will be spent on electricity costs. Of the $88 expense, $70 will have been used to heat the room, not light the room. If an 80% efficient LED system had been used, the electricity cost would be $23 per year - there would be a cost savings of $65 on electricity during the year. Realistically the cost savings would be higher as most incandescent light bulbs blow out within a year and require replacements whereas LED light bulbs can be used easily for a decade without burning out.
