Solar simulator

Abstract

The invention relates to a solar simulator which is characterized in that the solar simulator comprises a reflecting cover, the reflecting cover is provided with a parabola-shaped inner reflecting surface, and the parabola of the parabola-shaped inner reflecting surface is provided with a symmetry axis and a focus; the polyhedral light source comprises a polyhedral support and a main light-emitting part, the polyhedral support is provided with main installation faces used for installing the main light-emitting part, the main installation faces are all located near the focus of the parabola-shaped inner reflection face, and an included angle is formed between each main installation face and the symmetry axis. The device has the advantages that by adjusting the angles of the reflecting cover and the polyhedral light source and adjusting the main light-emitting piece and the auxiliary light-emitting piece, the light intensity difference of light rays emitted by the light source in all areas in the reflecting cover is small, and the situation that the sunlight simulating effect is affected by the light intensity distribution difference is avoided; on the basis that the sunlight simulator does not need to be equipped with a Rayleigh scattering plate, the sky color simulation effect close to or the same as that of a Rayleigh scattering panel can be achieved.

Description

technical field [0001] The invention relates to a light source, in particular to a solar simulator. Background technique [0002] With the improvement of people's living standards, the requirements for artificial lighting systems are also getting higher and higher. The lighting system that simulates outdoor sunlight can greatly improve the user's visual experience and has a high market prospect. [0003] The sunlight simulation lighting system mainly uses the principle of Rayleigh scattering. After the visible light emitted by the light source passes through the Rayleigh scattering plate, it forms a light blue light similar to the light blue light that appears in the earth's atmosphere under a clear sky state. In order to guide the observer to perceive the light source as the sun from a long distance, the light source in the lighting system has requirements for its brightness uniformity. [0004] In the currently known sunlight simulation lighting system, a light source mo...

Problems solved by technology

The light emitted by it is refracted by the lens or the reflector, and the light intensity at different positions in the center and periphery of each chip is quite different, and even the positions of multiple chips can be clearly observed, which seriously affects the effect of sunlight simulation. To reduce the brightness of the center, it needs to be realized through multiple diffusion plates, and the volume of the product is very large, which affects the effective indoor space height
