The present invention discloses a light concentrating type solar power generation device. The light concentrating type solar power generation device is simple in structure, low in manufacture cost andhigh in practicability. The device comprises a first convex lens; the top end of the first convex lens is provided with a light source sensor; a case is arranged to one side of the first convex; rotating telescopic rods are arranged at one side of the case; a light-shielding plate is arranged at one side of the rotating telescopic rods; the other side of the case is provided with a second convexlens; the outer side of the case is connected with a heat dissipation fan; a first solar panel is arranged to one side of the second convex lens; a concave lens is at on one side of the first solar panel; a second solar panel is arranged to one side of the concave lens; a solar storage battery is arranged at one side of the second solar panel; and a motor is arranged at one side of the solar storage battery. According to the light concentrating type solar power generation device of the invention, the first convex lens and the second convex lens interact with each other so as to concentrate sunlight, so that the working efficiency of the solar panels can be improved, a lot of costs can be saved, and the light concentrating type solar power generation device is suitable for being popularized.
