Abstract

An adjustable sunlight illumination system comprises a light condensation unit, inner wall total-reflection straight tubes, total-reflection straight tubes, corner reflection units and an illumination unit. The multiple total-reflection straight tubes and the corner reflection units are connected to form a sunlight transmission channel from outdoor to indoor. The light condensation unit is connected to the outdoor end of the sunlight transmission channel. The sunlight transmission channel further internally comprises a dimming unit comprising two spoke wheel type brackets which are concentrically coupled and can rotate relatively. One of the spoke wheel type brackets is fixedly connected with the inner wall of the sunlight transmission channel. The adjustable sunlight illumination system has the beneficial effect that the adjustable sunlight illumination system replaces traditional silica fibers high in cost to achieve the sunlight direct guiding-in function. A plastic optical fiber is adopted after light splitting at the indoor unit to ensure the advantages of system transmission power and low cost and also facilitates arrangement of an indoor complex illumination light path, and lighting points are set more flexibly. The wheel brackets of the dimming unit drive black-out cloth to shield the sunlight transmission channel when rotating relatively, so that the purpose of adjusting the light intensity is achieved.

Description

technical field [0001] The invention belongs to the technical field of renewable clean energy, and relates to the direct application of sunlight in lighting, in particular to an adjustable sunlight lighting system, in particular to a sunlight lighting system with adjustable brightness. Background technique [0002] Solar energy is an inexhaustible renewable clean energy. With the deepening of research on the development and utilization of solar energy in the 20th century, various technologies that utilize solar energy such as solar power generation and solar thermal utilization (water heaters) continue to Among them, sunlight lighting is an important direction of solar energy application. The specific plan is to collect sunlight under the sun through a device, and then guide the sunlight into the room through a light guide device (such as optical fiber, light guide tube, etc.) for lighting. Compared with solar power generation and then driving lighting with electric energy, ...
