Embodiment Construction

[0011] like figure 1 The schematic diagram of the convergence angle of the spherical xenon lamp source of the solar simulator is shown. The spherical xenon lamp source 1 is located at the first focus of the ellipsoidal reflective bowl, and the light converges at the second focus after being reflected by the ellipsoidal reflective bowl.

[0012] like figure 2 The schematic diagram of the uniform irradiation surface formed by multiple reflections of the light guide tube of the solar simulator and its uniformity are shown, and the irradiation surface is the A surface in the figure.

[0013] like image 3 The structure diagram of the solar simulator optical device with variable irradiated surface size and collimation angle is shown. The spherical xenon lamp light source 1 located at the first focus of the ellipsoidal reflective bowl is reflected by the ellipsoidal reflective bowl 2 and converges on the ellipsoidal surface at the first focus. A light spot of a certain size is fo...

Abstract

The invention relates to a solar simulator optical device with variable radiation surface sizes and variable collimation angles. The light beam emitted by a spherical xenon lamp light source enters a light guide pipe after being reflected and focused by an ellipsoidal reflecting bowl, and then passes through a specific structure composed of two lenses to meet the radiation requirement of different radiation surface sizes and different radiation collimation degrees by changing the focal length of one lens or changing the focal length ratio of the two lenses. Meanwhile, the double-lens specific structure can transform radiation surface uniformity into radiation space uniformity. The solar simulator optical device provided by the invention can be applied to solar simulated radiation of areas with different sizes, and can also be applied to suitable occasions of a solar simulator with high requirement on collimation degree. In addition, the solar simulator optical device has the advantages of reasonable design, simple structure, convenience in specific measurement operation and high practicability.

Description

technical field [0001] The invention relates to an optical system structure, in particular to a solar simulator optical device with variable irradiation surface size and collimation angle. Background technique [0002] The solar simulator is an optical device commonly used in the field of optics to simulate sunlight illumination, and has different requirements for its characteristics and parameters in different applications. In recent years, with the continuous development of the solar photovoltaic industry, especially in the field of the latest generation of concentrated photovoltaics, solar simulators with uniform irradiance and small collimation angles must be used to test cells, components and systems. However, at present, the collimation angle of most solar simulators is restricted by the system structure, which is fixed at a large value and cannot be changed. In the case of large-area irradiation, the system structure of the solar simulator is complex and huge. In the...
