  • Patent number: 8297828
    Abstract: The invention relates to a light guide panel capable of distributing light beams incident from a light source to an entire surface thereof. The light guide panel has at least two through holes formed in a path of the incident light beams, apart in a predetermined interval from a light incident surface. The through holes are formed perpendicular to the path of the incident light beams, and lined along the light incident surface of the light guide panel. The light guide panel according to the present invention can improve uniformity of incident light without increasing the number or size of the light source, thereby distributing the incident light in a wider angle and decreasing a light mixing region. The light guide panel is produced in a simple manufacturing process, reducing the manufacturing costs.
