Mirror-box-type all-cloudy day simulation device

Abstract

The invention discloses a mirror-box-type all-cloudy day simulation device. The mirror-box-type all-cloudy day simulation device comprises an optical reflection structure, electric light sources, a light diffusion film and a frame structure. The frame structure is an enclosed structure and the horizontal cross section of the enclosed structure is in the shape of a regular polygon or round. The electric light sources are arranged at the spatial top of the frame structure and the light diffusion film is arranged below the electric light sources. The optical reflection structure is a mirror reflection material arranged on the inner side of the enclosed structure, the mirror reflection material is formed by connecting a plurality of plane mirrors in a seamless mode, and the included angle formed by the mirror reflection material and the plumb line is zero point seventy seven degree. The upper end of the optical reflection structure is connected with the light diffusion film, and the lower end of the optical reflection structure is located at the lower end of a detected model storing platform in the height direction. According to the mechanism that light of an even light-emitting face at the top is reflected infinitely through the enclosed mirror structure, the mirror-box-type all-cloudy day simulation device accurately simulates the standard all-cloudy day sky brightness distribution published by the International Illuminating Engineering Society. The mirror-box-type all-cloudy day simulation device has the advantages of being small in size, ingenious in structure, accurate in brightness distribution and the like, and can be used for simulating the sky brightness distribution during all-cloudy days.

Description

technical field [0001] The present invention relates to an artificial device for simulating sky brightness, in particular to a full cloudy sky brightness simulation device, in particular to a mirror box type full cloudy sky brightness distribution simulation device, which is used for simulation testing of building lighting , which simulates the brightness distribution of the cloudy sky in a limited artificial space, and belongs to the field of architectural optics in architectural technology science. Background technique [0002] The architectural daylighting experimental platform is the foundation of architectural daylighting research and design. Building lighting is the most important factor in creating a building light environment: on the one hand, the efficient use of natural light can save energy consumption for building lighting. In my country, about 20% to 40% of the total energy consumption of buildings is used for artificial lighting, so efficient lighting is very i...

Problems solved by technology

Due to the limitation of the light environment construction method, it is difficult for the traditional dome-shaped artificial sky to accurately realize the sky brightness distribution of the CIE standard, which may easily lead to inaccurate measurement results of the daylighting coefficient
