The optical fiber illumination device and the photovoltaic power generation device are respectively connected with the intelligent dimming control system and the sun tracking system; according to the system, sunlight is divided into different wavebands, visible light is transmitted into a room through optical fibers for illumination, and other wavebands are transmitted to a photovoltaic cell for power generation; the intelligent dimming system can control the proportion of light beams irradiated on the dimming reflecting mirror and the frequency divider; meanwhile, under the action of the LED light supplementing lamp, stable indoor illumination and efficient solar energy utilization can be achieved; and the light beams irradiated on the optical fiber and the PV battery are homogenized, so that the safe and efficient operation of the system is ensured.

Description

technical field [0001] The invention relates to the field of solar energy utilization, in particular to an optical fiber lighting and photovoltaic power generation system of high-efficiency intelligent dimming type spectrum frequency division. Background technique [0002] In recent years, with the growth of population and the improvement of living standards, the global building area and complexity have continued to increase. Even in sunny days, indoors require a lot of electric lighting, which not only consumes a lot of energy but also pollutes the environment. Sunlight fiber optic lighting system is a technology that uses optical fiber to transmit concentrated sunlight to the room. This technology can provide natural and comfortable green lighting for the room. At the same time, the use of sunlight for direct lighting does not involve energy conversion and has high lighting efficiency. [0003] However, there are many problems in the practical application of optical fiber ...

Problems solved by technology

[0004] In the existing patented technology, there are also many disadvantages. For example, patents 201810081968.X and 2015100151163.1 only consider the use of sunlight for lighting, but do not consider the recycling of non-visible light bands, and do not consider the problem of unstable indoor lighting; patent 202010985814.3 Supplementary light from LED lights is used to maintain stable indoor lighting, but the power provided to LED lights comes from solar panels. The photovoltaic power generation and fiber optic lighting are completely independent systems that do not take into account the recycling of non-visible light bands; patent 201010565663.X utilizes light splitting The device realizes the recycling of non-visible light bands, but does not consider the problem of unstable indoor lighting. At the same time, the concentrating device, secondary emitter, and frequency division device of the invention are all exposed to the environment and are easily affected by dust.
