Sunlight holographic non-tracking focus illumination system

Abstract

The invention provides a sunlight holographic non-tracking focus illumination system. The system comprises a multi-layer holographic optical collector, an optical energy receiver, an optical fiber endsleeve head, an optical fiber and a scattering illuminator; each layer of the multi-layer holographic optical collector generates diffraction to incident light at a certain angle only; a large-anglenon-tracking light collection effect is achieved by virtue of multi-layer in-series superposition; the optical energy receiver is placed at a light focusing position of the multi-layer holographic optical collector and is connected with the optical fiber end sleeve head and the optical fiber; the optical fiber end sleeve head is used for restraining a multi-core optical fiber within the range of the optical energy receiver; the multi-core optical fiber can be used for transmitting optical energy and dividing the light into a plurality of beams so as to realize multi-user illumination; and thescattering illuminator is connected with the tail end of the optical fiber and is used for scattering the optical energy inside the optical fiber to form indoor illuminating light which is transmittedin all directions and also counteracting a part of chromatic dispersion influences of the holographic optical collector and the optical fiber. According to the sunlight holographic non-tracking focusillumination system provided by the invention, sunlight is focused and directly brought in a room for illumination, thus the problems about low solar battery efficiency, high cost and pollution existing in the photovoltaic conversion technology are prevented, so the sunlight holographic non-tracking focus illumination system is environmentally friendly, safe and reliable.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to an indoor lighting system realized by using a multi-layer holographic technology and a light guide technology. Background technique [0002] Solar energy is a kind of renewable energy, which has the advantages of universality and cleanness of development and utilization. It has become an effective way to solve problems such as energy shortage, greenhouse effect and environmental pollution. In solar lighting technology, especially direct light guide lighting has stronger potential. This lighting method does not have the problems of low efficiency, high cost and pollution of solar cells in photoelectric conversion technology. After focusing sunlight, it is directly introduced into indoor lighting. It not only greatly reduces lighting energy consumption, but also is safe and environmentally friendly. [0003] In addition, the traditional concentrating system is generally equipped ...
