Dome skylight, light-collecting device and illuminating system

Abstract

The invention discloses a dome skylight, a light-collecting device and an illuminating system. The dome skylight comprises a selective reflector, a light receiver and a shade body, wherein the selective reflector is provided with a concave mirror type lighting surface, and can at least partially reflect and converge radiation irradiating on the lighting surface and provided with a first wavelength and enable at least part of radiation irradiating on the lighting surface and provided with a second wavelength to transmit and pass; the light receiver is positioned on the backlight side of the selective reflector and used for receiving the radiation transmitting and passing through the selective reflector; and the shade body is used for supporting both the selective reflector and the light receiver. The dome skylight, the light-collecting device and the illuminating system can comprehensively utilize solar energy more sufficiently.

Description

technical field [0001] The invention relates to the field of lighting and lighting, in particular to a lighting cover, a light collecting device and a lighting system. Background technique [0002] Using sunlight for indoor lighting is a new type of green lighting solution. It can collect and transport sunlight into the interior of the building, instead of lights for lighting. This can realize the full utilization of natural resources, and can save energy. However, current daylighting systems have low light efficiency and can utilize less sunlight. Moreover, the function of the current daylight lighting system is relatively single, which can only collect and transmit sunlight. Furthermore, the current daylight lighting system can only realize lighting when the sunlight is relatively sufficient, but it is difficult to realize lighting at night or in rainy weather. Contents of the invention [0003] One of the objectives of the present invention is to provide a multi-fun...
