Abstract: A light guiding system includes an ambient light gathering system, multiple light guiding devices and a wedge light guiding bar. The ambient light gathering system facing ambient light is used for absorbing the ambient light. Each light guiding device absorbs the absorbed light. The wedge light guiding bar has a light-out surface and a light-in surface coupled to the light-out surface. The light-in surface is a wide surface coupled to an inclined surface. The light-out surface is opposite to the inclined surface and next to a light-in side of a light guide plate. The wedge light guiding bar for use in the light guiding system, an edge-lighting backlight module and an LCD device can reduce cost of material and weight. Also, the light uniformity of the light output end is improved and the optical quality of the edge-lighting backlight module is raised.

Abstract: A backlight module is disclosed. The backlight module includes an ambient light collector for collecting ambient lights, at least one optical fiber connecting to the ambient light collector, a light emitting plate arranged closely to an optical plate, at least one fixing sleeve being received in the through hole, and at least one optical fiber sleeve. The light emitting plate includes a plurality of through holes. The optical fiber sleeve is fixed within the fixing sleeve and engages with the light emitting ends of the optical fibers to fix the optical fibers on the light emitting plate. The backlight module utilizes the ambient lights as light source. In addition, by cutting the light emitting end of the optical fibers, the light emitting angle of the lights are greatly enlarged. As such, the brightness difference is decreased and the display performance is enhanced.
