Embodiment 1

[0016] Example 1: Such as figure 1 As shown, a multi-functional full-spectrum sunlight utilization device includes a solar concentrator 7, a cold mirror 4, an infrared light collection module 2, an upper bracket 3, a lower bracket 5, which are used to transmit visible light and Ultraviolet light transmission fiber optic cable 9, fixed metal tube 6, column bracket 8 and mechanical fixing and rotation control module 10. The solar concentrator 7 is movably connected to the mechanical fixing and rotation control module 10 through the column bracket 8. The cold mirror 4 is fixedly connected between the reflective surface and the focal point of the solar concentrator 7 through the lower bracket 5, and the infrared light collection module 2 is fixedly connected to the infrared light focal point of the solar concentrator 7 through the upper bracket 3. The upper half of the transmission optical cable 9 is fixed by a fixed metal tube 6 fixed at the central opening of the reflective surfac...

Embodiment 2

[0021] Example 2: Such as figure 2 As shown, the main difference between this embodiment and Embodiment 1 is: Embodiment 2 replaces the cold mirror 4 in Embodiment 1 with a hot mirror 41. Based on this change, a multifunctional full-spectrum sunlight utilization device of this embodiment includes a solar concentrator 7, a heat mirror 41, an infrared light collection module 2, an upper bracket 3, and a lower bracket 5 that converge sunlight. , The transmission optical cable 9 used to transmit visible light and ultraviolet light, the fixed metal cylinder 6, the column bracket 8 and the mechanical fixing and rotation control module 10. The solar concentrator 7 is movably connected to the mechanical fixing and rotation through the column bracket 8. On the control module 10, the hot mirror 41 is fixedly connected between the reflective surface and the focal point of the solar concentrator 7 through the lower bracket 5, and the incident light end surface of the transmission optical c...

Embodiment 3

[0026] Example 3: Such as image 3 As shown, the main difference between this embodiment and Embodiment 1 and Embodiment 2 is: the solar concentrator 7 of this embodiment is a transmissive Fresnel solar concentrator instead of a reflective Fresnel solar concentrator. Based on this change, a multifunctional full-spectrum sunlight utilization device of this embodiment includes a solar concentrator 7 that condenses sunlight, a fixed metal plate 71, a fixed bracket 72, a hot mirror 41, and an infrared light collection module 2. The upper bracket 3, the lower bracket 5, the transmission optical cable 9 for transmitting visible light and ultraviolet light, the column bracket 8 and the mechanical fixing and rotation control module 10, the fixed metal plate 71 is movably connected to the machine through the column bracket 8 On the fixed and rotating control module 10, the solar concentrator 7 is fixedly connected to the fixed metal plate 71 through the fixed bracket 72, and the hot mirr...

Description

Technical field [0001] The present invention belongs to the field of lighting technology, and particularly relates to the technical field of separating sunlight for different purposes. Background technique [0002] Due to the increasing depletion of traditional fossil energy sources, such as oil and coal, which are currently used in large quantities, and with the development of the economy, energy consumption is showing a rapid growth trend, and the energy crisis is becoming increasingly prominent. In modern society, lighting energy consumption accounts for a high proportion of the entire electrical energy consumption. Reducing lighting energy consumption is the top priority for energy conservation, emission reduction and sustainable development. [0003] As a clean, pollution-free renewable energy source, solar energy is increasingly being valued by countries all over the world. Converting solar energy into electrical energy will greatly reduce traditional energy consumption. For...
