摘要： The present invention discloses a linear light source having light guide with tapered saw tooth structures for Charge Coupling Device Module (CCDM). The linear light source comprises a light guide and at least two Light Emitting Diodes (LED's). The light guide includes two incident surfaces, a reflective surface, two refractive surfaces and an ejective surface. The reflective surface has a tapered saw tooth structure; the LEDs are disposed at two ends of the light guide. Upon emission of light from the LEDs, light enters into the light guide, reflected by the tapered saw tooth structures, and then ejected from the ejective surface. It is possible to form a U-shaped lambert distribution in the sub scanning direction, thereby generating the complementary effect for the pickup lens and the CCD image sensor of CCDM, as well as to create a linearly converged lambert distribution in the main scanning direction.
