A light pipe of vehicle signal lamp



A light pipe of a vehicle signal lamp comprises a light pipe, an LED light source component arranged at two ends of the light pipe, and consecutive teeth-form reflection configurations formed on one side inside the light pipe. The light pipe of the vehicle signal lamp proposes a novel light distribution scheme and lighting effect that an LED is adopted as a vehicle lamp of light source, and solves the problem that when the light pipe is used as an illuminating lamp, the luminance value is not high enough under the circumstance of large teeth-form inclined installation, and novel style/strap-shaped or face-shaped uniform and soft illumination effect can be achieved, so that the LED can not directly emit into the eyes of other drivers at the rear part of a vehicle as a point light source, and the circumstance of discomfort glare can be prevented, thereby ensuring driving safety.
