    The function of the light guide bar light source module

    Through the light diffusion structures on the incidence surface of the light guide bar and the full-reflection action of the light inside the light guide bar, the light guide bar can provide illumination with uniform brightness; and moreover, the utilization rate of. Through the light diffusion structures on the incidence surface of the light guide bar and the full-reflection action of the light inside the light guide bar, the light guide bar can provide illumination with uniform brightness; and moreover, the utilization rate of. The invention discloses a light guide bar and a light source module adopting the same. On a cross-sectional plane of the light guiding bar, there is a first line interval on the upper surface. A second line interval, a third line interval and a. Modern light guides are used for the transportation of light signals from a circuit-board-mounted LED via a particular route to a defined light-emitting surface, with minimal loss and blurring effect. They are used to illuminate areas that are too small or too hazardous to permit the installation of a light bulb.
