Abstract

The invention discloses a sunlight collecting and transmitting device which at least comprises a lighting device, a light conduit and a diffuser, wherein the light conduit is connected with the lighting device, the diffuser is connected with the other end of the light conduit, the lighting device is a dome type lighting cover, the top end of the lighting cover is provided with a fixed hanging end which is at least connected with a cantilever, and at least one reflective mirror is arranged on the cantilever. By regulating the angle and the position of the reflective mirror, the lighting efficiency of a system can be effectively increased, especially when sunlight shines in a small degree. A solar panel and a positioner can be arranged on a transmission shaft, and thus, the position of the reflective mirror can be changed according to an irradiation angle of the sun. By regulating the angle and the position of the reflective mirror, the lighting efficiency of the system, can be effectively increased, especially when sunlight shines in a small degree.

Description

technical field [0001] The invention relates to a sunlight collection and transmission device, which is a device that can collect outdoor sunlight and transmit it to the room for lighting. Background technique [0002] At present, indoor lighting generally means that buildings are provided with windows, and external sunlight is introduced into the room through windows. For buildings that are relatively closed and cannot be directly illuminated, lighting fixtures are generally used for indoor lighting. During the use of lighting lamps, electric energy is wasted, and there are potential safety hazards, especially for some processing workshops, shopping malls and other environments. In addition, the lighting of electric energy can only provide lighting of a single wavelength, while the emission spectrum of sunlight has a wider band, and lighting with sunlight makes people feel more comfortable. [0003] In order to introduce sunlight into buildings that cannot be directly illu...
