The LED Light is Always Progressing

Why so many corporations are trying to enter into the LED illumination field? Why the LED market is so active? Because the price and the luminescence efficiency of the LED light has been greatly improved.

Firstly, the luminescence efficiency is improved year by year. The JLEDS had predicated that the luminescence efficiency could be 120lm/W in the year of 2009, and it would be 150lm/W in 2015. But the development in recent two years had exceeded the predication. The LED light illumination is three percent to five percent of the LED chip, because it is always influenced by the electric power loss and temperature increase. The illumination was 50lm/W to 70lm/W traditionally, which has increased to more than 80lm/W at the present time. It is predicated that the LED light will surpass the efficiency of fluorescent lamp in the year of 2012.

The price of the LED light is decreasing all the time, which is regarded as another important element of the light market. From the integrated cost point of view, the LED light is better than the fluorescent lamp. For example, the LED light with forty thousand hours service life, which is 60W, will cost one hundred US dollars; the incandescent lamp with one thousand hours service life can cost five hundred US dollars. If the light is on for more than fourteen hours, the LED light can be the cheapest among all different kinds of the lights.

It is predicated that the cost of the LED chip will be lower than one yen per lm, and this goal will soon come true. Experts maintain that the rate of descend will be two percent every year. The manufacturing of the incandescent lamp is stopped, therefore, the popularization of the new light will speed up. More and more corporations have entered into the LED business field to prepare for the increasing demands of future three years. The related integrated circuit is X5130.
