Abstract

The invention relates to a multifunctional full spectrum sunlight utilizing device, which comprises a solar energy condenser, a cold mirror, an infrared light collecting module, an upper support, a lower support, a transmission cable, a fixing metal drum, a cylinder body support and a mechanical fixing and rotating control module, wherein the solar energy condenser is used for converging the sunlight and is movably connected to the mechanical fixing and rotating control module through the cylinder body support, the transmission cable is used for transmitting visible light and ultraviolet light, the cold mirror is fixedly connected between a reflecting surface of the solar energy condenser and a focal point through the lower support, the infrared light collecting module is fixedly connected at the position of an infrared light focal point of the solar energy condenser through the upper support, the upper half part of the transmission cable is fixed through the fixing metal drum fixed at the position of an opening hole at the center of the reflecting surface of the solar energy condenser, and an incident light end surface at the upper half part of the transmission cable is positioned at the position of the ultraviolet light focal point of the solar energy condenser. The multifunctional full spectrum sunlight utilizing device disclosed by the invention has the beneficial effect that the light spectrum components of the visible light, the infrared light and the ultraviolet light in a sunlight spectrum can be utilized.

Description

technical field [0001] The invention belongs to the technical field of lighting, in particular to the technical field of separating sunlight for different purposes. Background technique [0002] Due to the depletion of traditional fossil energy such as petroleum and coal, and with the development of the economy, the consumption of energy is increasing rapidly, and the problem of energy crisis has become increasingly prominent. In modern society, the energy consumption of lighting accounts for a high proportion of the total electric energy consumption. Reducing lighting energy consumption is an urgent task for implementing energy conservation, emission reduction and sustainable development. [0003] Solar energy, as a clean, non-polluting renewable energy, is increasingly valued by countries all over the world. Converting solar energy into electrical energy will greatly reduce traditional energy consumption. For lighting systems that account for a large proportion of energy ...
