A device and a method for detecting a light irradiating angle are disclosed. The device, used to detect the incident direction of a light ray, includes a solar sensor and a processor. The sensing unit of the solar sensor has sensing areas. The sensing areas correspondingly generate sensing signals based on the intensity of the light ray. A mask covers the sensing unit and has an X-shaped light transmitting portion. The light ray transmits the X-shaped light transmitting portion to form an X-axis light ray and a Y-axis light ray. The X-axis light ray intersects the Y-axis light ray. The X-axis light ray and the Y-axis light ray fall on the sensing area. The processor, coupled to the sensing unit, receives the sensing signals and determines information of the incident direction according to the sensing signals.

A polyhedron device for sensing light rays and detecting incident directions of the light rays includes a polyhedron mounting seat. The polyhedron mounting seat includes a bottom surface, a top surface, and side surfaces, wherein the bottom surface is opposite to the top surface. The side surfaces, located between the top surface and the bottom surface and inclined to the bottom surface, face toward different directions. The side surfaces are respectively provided with first light sensors. The top surface is provided with at least one second light sensor. The specific design of the polyhedron mounting seat is provided to the sensor for detecting a light ray at a larger angle, thereby measuring the finer data.
