New Type of Uniform Light Device for Solar Simulator
The uniformity of irradiance intensity is an important parameter of a solar simulator. There are some problems, such as designing complexity and high cost, in the process of using an optical integrator to obtain uniformity light. The microsphere surface reflective lens is pressed by the ultra-efficient mirror with the moulds prepared by three-dimensional printing technology. A new type of uniform light device is composed of two microsphere surface reflective lenses and a cylindrical light pipes. The non-uniformity of irradiance intensity of a light spot with a 150 mm diameter is 1.12% obtained by the principle of diffuse reflection of light. The result reaches the A level of IEC 60904-9. The new type of uniform light device has some characters such as simple structure, high utilization rate of light source, and low cost.
