Article Preview

Compared with traditional lighting, LED has many unparalleled advantages, and is considered to be the most promising green light which may be able to substitute incandescent and fluorescent lamps. The requirement of LED's luminous efficiency grows with its increasingly application in the lighting field. This paper summarizes the development of gaining approaches of Power-type WLED and their respective advantages and disadvantages; analyses several effective programs which can improve luminous efficiency, including changing substrate materials as to enhance the heat-release performance as well as the impact of chip structure design, the packaging materials and technology or other factors; proposes a new LED packaging material- inorganic fluorescent glass, which is expected to simplify the packaging process greatly, at last, there is an expectation of High-power WLED in future application.
