Three-dimensional curve perfect diffusion solar simulator

Abstract

The invention provides a three-dimensional curve perfect diffusion solar simulator. A D50 linear tube is taken as a standard linear light source (1); a curve diffuse reflection device (3) and a curve specular reflection device (2) are arranged along an axis of the linear light source; a diffuse transmission curve element (4) is arranged on a light path; and the uniformity of light of a plane where an irradiated object is positioned meets the requirement through multiple times of internal reflection and transmission of the light so as to improve optical spectrum performance. The three-dimensional curve perfect diffusion solar simulator has the basic integrating sphere function, meets the requirement of large area diffuse reflection illumination, has low manufacturing difficulty, solves theproblems of the uniformity of the light and spectrum fitting and matching, and meets the requirement of three-dimensional printing, grating manufacturers and holographic paper manufacturing enterprises on the special illumination condition.

Description

technical field [0001] The invention relates to a three-dimensional curved surface diffuse reflection sunlight simulator, which converts linear light into relatively ideal diffuse reflection light by mechanical means. Background technique [0002] At present, providing a stable diffuse light source is an important experimental and observation requirement in the fields of chromaticity detection, photometric detection, solar cell detection, lenticular printing, and three-dimensional printing quality detection. The performance of diffuse light directly affects the detection accuracy of the instrument. Test data reliability, and the stability of quality evaluation. [0003] In the existing technology, the lighting conditions that can provide stable diffuse light are mainly divided into three types of equipment, one is the integrating sphere diffuse light generator, which is also a device with the best diffuse light simulation effect at present; the second is the flat plate diffu...

Problems solved by technology

However, the integrating sphere is small in size and has high requirements on the manufacturing process and materials. In addition, due to the unique spherical structure of the integrating sphere, it is not suitable for visual observation and comparison of large-format samples, so the integrating sphere equipment is not suitable for the size and volume of the object to be illuminated. Larger and related fields that require human visual observation

[0005] The light source power of the flat-panel diffuse reflection simulator is small, the manufacturing process is complicated, and the scope of use is limited. It is mostly used in the fields of monitors, rear-projection TVs, etc.

[0006] The mechanical optical path simulates the diffuse light generator, and realizes the diffuse light simulation effect through mechanical design. The size of this type of equipment is adjustable, the equipment components are easy to replace, the irradiation area is large, and the diffuse light performance is stable, which can meet the requirements of specific fields. At present, There are a small number of such equipment used in the testing field of solar cells, but there are few equipment specially used for photometric measurement, colorimetric measurement, and colorimetric inspection of grating products
