Why energy saving led lighting save energy?

LED street light bulbs will be soon widely used in the future of household lighting, in street lights, outdoor signs and offices because of its energy-saving and environment protection. Why energy saving led lighting save energy?

Monochromatic light of high brightness LED has made great progress in markets. Although they are more expensive than traditional light bulbs, their advantages can be offset by its higher price. First of all, In order to achieve brightness, a red LED light will consume 15 watts, while the traditional bulb will have to consume up to 150 watts of energy. In addition, according to scientists testing, when LED power light, 10% of the energy can be transformed into light but only  7-8% of the conversion efficiency of incandescent bulbs. Taking the above information into consideration, in order to achieve the same lighting effects, LED lights than incandescent energy saving is obvious.

Of equal importance, the key strength of energy saving led lighting is reduced power consumption. 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). 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.

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 high bay 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.

It will be interesting to see what developments are coming for more residential applications of energy saving led lighting. LED lighting technology has been researched and developed for the past two decades We in the industry are certain that tomorrows LED lights will last longer and consume even less power than todays energy efficient led light bulbs. LED lighting will be used to replace virtually every type of light, bulb, and lamp that is currently in use.
