Novel solar illumination device

Abstract

The invention discloses a novel solar illumination device. The device comprises a plurality of sunlight collectors, a plurality of sunlight illumination lamp caps and a plurality of sunlight transmission units which are used for transmitting sunlight energy collected by the sunlight collectors to the sunlight illumination lamp caps, wherein each sunlight collector is composed of a condenser lens and a secondary reflective coupler connected with the condenser lens; the sunlight illumination lamp caps are beam splitting lenses; the sunlight transmission units are photoconductive fibers; a protective cover is arranged outside the plurality of sunlight collectors; and a sunlight tracker is arranged at the top end of the protective cover. The solar illumination device has the advantages of simple structure, reasonable design, uniform illumination effect, long service life, good use effect and convenience in popularization and application, and can be used for enlarging the field of solar development and utilization and improving the solar utilization efficiency.

Description

technical field [0001] The invention belongs to the technical field of solar lighting, and in particular relates to a novel solar lighting device suitable for lighting places such as underground garages, tunnels and houses with poor light. Background technique [0002] At present, people have made rapid progress in the utilization of solar energy. As typical examples of new energy utilization, solar water heaters and solar panels have achieved large-scale production and commercial operation. However, the device and technology for directly using solar energy for lighting are not yet mature. If solar energy is to be used for lighting, it is necessary to convert light energy into electrical energy through solar cells, and the electrical energy is stored or transmitted, and then converted into light through lamps and lanterns. energy, the energy is applied to actual lighting after the conversion of light-electricity-light, the conversion process is complicated and the efficiency...

However, the device and technology for directly using solar energy for lighting are not yet mature. If solar energy is to be used for lighting, it is necessary to convert light energy into electrical energy through solar cells, and the electrical energy is stored or transmitted, and then converted into light through lamps and lanterns. energy, the energy is applied to actual lighting after the conversion of light-electricity-light, the conversion process is complicated and the efficiency is low, and because the conversion efficiency of solar cells that can be mass-produced is generally not high, resulting in low energy utilization , and the equipment cost is high
