Description

Indoor light recycling module

The present invention relates to an indoor light recovery module, and more particularly to a device for indoor or confined space, which is composed of a concentrating mirror and a photoelectric conversion battery.

Since solar energy is a green and environmentally friendly energy source, the destructiveness of the ecological environment is smaller than other energy sources, so more and more countries encourage the development of solar cells.

One of the solar devices is used in an indoor environment, and the device can be placed at the window to generate electricity by absorbing sunlight that is irradiated into the room through a transparent window. However, there is a serious problem in the application of such a device. Since the angle at which the sun enters into the room varies from time to time, it is necessary to install a chasing device to improve efficiency. In fact, indoor lighting can also be regarded as a kind of "fixed sunlight", which is mainly to provide sufficient illumination in the room. However, most of the light is scattered on the wall and disappeared by scattering or absorption of building materials. Recycling will help to improve energy efficiency.

Therefore, the applicant of this case considered it necessary to carry out the required opto-mechanical design for the recycling of indoor lighting.

Therefore, the purpose of the present invention is to provide an innovative auxiliary mechanism for transferring the light of the indoor lighting fixture to the photoelectric conversion battery (or solar battery), thereby improving the efficiency of using the electrical energy.

Therefore, the novel light recycling module comprises: a light-shielding mirror group or a reflecting device and a solar panel.

The collecting mirror unit has the function of collecting the incident light to concentrate the incident light.

The solar panel unit has a concentrating surface for receiving light.

The reflecting device can be adjusted to a position relative to the light collecting surface of the solar battery unit by the design of the mechanism.

The reflecting device can be an approximately parabolic reflecting cup. The structure is configured to reflect light so that the light is concentratedly transmitted to the light collecting surface of the solar cell unit through the reflecting device.

Compared with the prior art, the indoor light recycling group is used for indoor light collection, and because of the addition of a light collecting device near the side of the indoor lighting fixture, the collected light can be concentrated on a solar pool to reduce the required solar cell area, thereby reducing the required solar cell area. It can increase the photocurrent per unit area. Furthermore, the light collecting means may be constituted by a collecting lens or a reflecting means (or a combination of both).
