In many families, organizations, governments and industrial applications, high brightness white LED has the trend to replace the traditional ones. Over the last year, white LED lighting takes a share of 50 percent in the total lighting applications, surpassing applications of color LED. Demand for beauty is the driving force of color LED while low power consumption is the selling point of white color LED.

High efficiency of LED will reduce the power by at most 88 percent in many conditions and it also reduces the carbon dioxide emission caused by producing electricity and transforming electric power. Viewing from commercial aspects, LED industry will become an industry which will bring more and more benefits in the future. According to some calculations, there is 10 percent of the total energy on the globe will be saved for the usage of LED lighting instead of the traditional incandescent lamps. As people all over the world have spared no effort to reduce the emission to the minimum, it is a great impetus for this transformation.

Besides the described above, in such an world which environmental protection is put great emphasis, LED lighting needs not to process and clean the poisonous gas in the fluorescent lamp which usually contains as much as 5mg mercury and even more. Furthermore, time that LED lights spend is as much as ten thousand hours ,which enables LED into the terminal applications.

There are also some advantages that LED has. For example, small size and long life span enable it to be applied in ares like under water project. Challenges keep abreast with these advantages as well. At present, the greatest challenge is how to optimize all these advantages. Because LED needs a relatively steady DC power supply, so a proper design of LED drive is needed under some conditions. Related chip is:LB1407 .
