Patent ID: 8111460

Claim:
A solar tracking skylight system for illumination, comprising a light guide, a solar tracking controller, a two-axis tracking mechanism, an energy converter and energy storage system, and a weather protective cover, the two-axis tracking mechanism is a base body provided with a gear ring, gear teeth are formed on one side of the gear ring, and the gear teeth couple with a motor, supporting rods are fitted to an upper end surface of the gear ring, a cross bar is located on the supporting rods, and a gear rack is formed at one end, driven by a motor located thereat; the light guide is provided with a light guide plate, a light amplifying plate and a light filter, wherein the light guide plate is located on the supporting rods, the light amplifying plate is located within the gear ring, and the light filter is located in the light path of the light guide plate and the light amplifying plate; the solar tracking controller is suitably located on the two-axis tracking mechanism, and is provided with photoconductive cells (photoresistors) mounted on a circuit board at a lower end thereof, to implement solar tracking, the circuit board comprises at least a Schmidt circuit, an OPA (Optoelectronic Pulse Amplifier) amplifying circuit, and a Wheatstone bridge circuit; the energy converter and energy storage system is fitted to one side of the two-axis tracking mechanism, to store electrical energy for use by the system, the energy converter and energy storage system comprises a solar energy panel, a battery and a circuit board; the weather protective cover is located on the outer edge of the two-axis tracking mechanism, and covers the entire mechanism, the weather protective cover has the characteristic of being pervious to light to facilitate the penetration of a light source; accordingly, the solar tracking skylight system for illumination is assembled to readily collect and diffuse light to form uniform light that is guided indoors for illumination use, eliminating the need for external power, and achieving the objective of saving energy and reducing carbon emissions.
