Patent ID: 8859893

Claim:
A light collection module comprising: a light guiding material having a first surface and a second surface opposite to each other and the light guiding material comprising: at least one first light guiding structure configured on the first surface to define a first area in the light guiding material, the first light guiding structure comprising a first light guiding surface and a first auxiliary surface connected with and asymmetric to each other, the first light guiding surface and the first auxiliary surface being intersected in a first angle, and a tip of the first angle pointing to the inner portion of the light guiding material; at least one second light guiding structure configured on the first surface to define a second area in the light guiding material, the first area and the second area being alternatively arranged, the second light guiding structure comprising a second light guiding surface and a second auxiliary surface connected with and asymmetric to each other, the second light guiding surface and the second auxiliary surface being intersected in a second angle, tip of the second angle pointing to the inner portion of the light guiding material, and an inclination direction of the first light guiding surface being opposite to an inclination direction of the second light guiding surface; and at least one solar energy receiving element disposed on at least one of the first surface and the second surface of the light guiding material, wherein the solar energy receiving element is located at a third area outside of the first area and the second area and the third area is located at a periphery of the light guiding material wherein the second area is disposed between the first area and the third area; wherein the first area is configured to transmit a light beam in a first path more parallel to the second surface than a corresponding incident path, and the second area is configured to transmit the light beam in a second path less parallel to the second surface than another corresponding incident path.
