Abstract

The invention discloses a light collecting device and relates to the field of natural lighting for building applications. The present invention includes a light guide tube and a light collector assembly, the light collector assembly is fixedly installed on the upper end of the light guide tube, and is characterized in that the light collector assembly is in the shape of a square prism, and the light collector assembly is The composition includes the east light guide grid assembly, the metal skeleton, the west light guide grid assembly, the south light guide grid assembly, and the north light guide plate, the east light guide grid assembly, the west light guide grid assembly, Both the south light guide grid assembly and the north light guide plate are fixed on the metal frame. The angle of the light guide grid sheet designed in the present invention greatly optimizes the path of sunlight according to the sun's running track, and improves the collection rate of sunlight in different time periods, and the invention designs a movable light guide grid assembly, which is flexible through the angle adjustment device Adjusting the light guide grid assembly to the best matching angle improves the collection rate of sunlight in different seasons.

Description

technical field [0001] The invention relates to the technical field of natural lighting applied in buildings, more specifically, to a light collecting device. Background technique [0002] The principle of the lighting device with light-gathering function of the light guide lighting system existing in the market is similar to this principle: that is, the lighting surface is made into a prism by using PC (polycarbonate) or PMMA (acrylic) material and using lamination or injection molding technology. Form, using the principle of light refraction of prisms to change the angle at which low-angle sunlight enters the light guide cylinder, thereby improving the lighting efficiency of sunlight in a certain solar altitude range, and using the raised lighting with a prism structure The hood can effectively increase the lighting area under the condition of direct light (simply speaking, it is sunny), and it can indeed increase the lighting efficiency by about 10%-20% compared with the ...
