摘要：
We propose a linear light Source using light emitting diode (LED) and a light diffusion bar for linear illumination. In order to get high illumination efficiency, the following factors of the illumination system have been investigated: (I) the effect of the diffusion area, (2) the effect of the relative size of LED and the light diffusion bar. In conclusion, a bigger diffusion size will produce higher emitting efficiency, mid a small relative size of emitting surface of LED and cross section of the light diffusion bar will also achieve higher emitting.
