Light conducting device, backlight module and display device

摘要

The present disclosure provides a light conducting device, a backlight module and a display device. The light conducting device cooperates with a light source to form a backlight module. The light conducting device includes at least one light receiving surface. The light receiving surface includes a plurality of annular sub-receiving surfaces configured to cause received light from the light source to be emitted in a single direction.

主权项

1. A light conducting device, comprising:
at least one light receiving surface, wherein the light receiving surface comprises a plurality of annular sub-receiving surfaces configured to receive light from a light source and emit the light in a single direction; wherein the light receiving surface is provided with an accommodation space with the light source being received therein, each of the sub-receiving surfaces surround the accommodation space, and each of the sub-receiving surfaces are configured to reflect the light received from the light source and emit the light in the single direction; each of the sub-receiving surfaces includes an inclined surface, and angles between the sub-receiving surfaces and the single direction are increased in an outward direction from the accommodation space; the light conducting device further comprises a first reflecting surface and a second reflecting surface; the first reflecting surface is provided on the accommodation space, the second reflecting surface is disposed above the accommodation space, and the first reflecting surface and the second reflecting surface are disposed oppositely and spaced from each other; the first reflecting surface is configured to receive light from the light source and cause the light received from the light source to travel in the single direction towards the second reflecting surface; the second reflecting surface is configured to reflect light transmitted from the first reflecting surface to the light receiving surface; and wherein each portion of the second reflecting surface is a transmission-reflection surface.
