Abstract |
LEDs, compared to conventional light sources, have many advantages and their applications are rapidly expanding, especially in areas such as back-lights for LCD. In this paper, we propose a new LED lamp structure suitable for applications requiring a low power. In the proposed LED lamp structures, LED chips are mounted on a transparent polycarbonate plate, and thus photons are transmitted through the both sides of the plate. The copper layer deposited on the polycarbonate plate is patterned to form circuit patten and the chip mount pad, on which LED chips are mounted. We speculate that our propsed LED lamp structures may be used as a type of plate light source. |
