Focusing solar light guide module

A focusing solar light guide module, applied to guide sunlight to an energy conversion device, comprising:

• a lens light guide plate, having a lens array and a plurality of microstructures,
• wherein the lens array is integrally formed on a surface of the lens light guide plate and the microstructures are disposed on another opposite surface of the lens light guide plate,
• the lens array comprises a plurality of lenses, each of the plurality of lenses has a curved surface, one of curved surfaces of the plurality of lenses is directly connected to adjacent curved surfaces so that the curved surfaces of the plurality of lenses are continuously arranged to form a curved exterior surface of the lens light guide plate, the lens array receives and focuses the sunlight, some of the sunlight traveling inside of the lens light guide plate is totally internally reflected by at least two lenses of the plurality of lenses after being reflected by the microstructures,
• the microstructures comprise at least one depressed area and at least one connection area, the connection area is connected between the depressed areas, the depressed area comprises a depressed point, a first inclined plane and a second inclined plane, wherein the first inclined plane and the second inclined plane are respectively located on the different sides of the depressed point, the first inclined plane and the second inclined plane are respectively connected between the depressed point and the connection area adjacent to the depressed point,
• after being focused by the lens light guide plate, the sunlight is reflected by the depressed area and then reflected by the connection area in sequence and is guided into the lens light guide plate by the total internal reflection, and the sunlight passes through at least one side surface of the lens light guide plate, and the energy conversion device disposed on or near the side surface of the lens light guide plate receives the sunlight passing through the lens light guide plate and converts the sunlight into an electric power.
