AI Technical Summary

Problems solved by technology

The radiation in the infrared band of the metal halide lamp is small, and the heat dissipation is obviously better than that of the xenon lamp, but the cost of the metal halide lamp is higher than that of the xenon lamp, and its irradiance and spectral matching are also weaker than that of the xenon lamp.

specific Embodiment approach

[0014] Specific embodiments: the present invention will be further described below in conjunction with the accompanying drawings

[0015] Such as figure 1 As shown, the solar simulator of the present invention includes a main light source and a filter device, a main light source power supply, an auxiliary light source and a filter device, an auxiliary light source power supply, a temperature detection module, an irradiance detection module, a spectrum detection module, and an optical path adjustment Modules, time control circuits, and the main control system connected to the above functional components.

[0016] In this example, a 500-watt xenon lamp is used as the main light source of the solar simulator as the main light source and filter device. The light spectrum generated by the 500-watt xenon lamp is relatively closer to the spectrum of sunlight, which makes the simulator more meaningful for display. The xenon lamp is connected with the main control system through the p...

Abstract

The invention relates to a high-accuracy sunlight simulator, and belongs to the technical field of sunlight simulating. The sunlight simulator comprises a main light source and filtering device, an auxiliary light source and filtering device, power sources, a temperature detection module, an irradiance detection module, a spectrum detection module, a time control circuit and a main control system for being connected with the functional parts. According to the high-accuracy sunlight simulator, a xenon lamp is used as a main light source, and LED lamps capable of adjusting the illumination intensity serve as auxiliary light sources; under the condition that a xenon-lamp light source is aged (in other words, the irradiance of light emitted by the light source is reduced, and a spectrum is shifted), as the LED-lamp auxiliary light sources are automatically adjusted, the irradiance output by a system on the measuring position is basically invariant, and the spectrum matching rate is basically invariant; the influence of the temperature on the accuracy of the irradiance of output light can be removed through the sunlight simulator.

Description

technical field [0001] The invention relates to a solar simulator device and belongs to the technical field of solar simulation Background technique [0002] Solar simulators are in great demand in terms of solar energy utilization and solar cell research. Due to the influence of various factors, the outdoor sunlight cannot get the desired light intensity anytime and anywhere. Even if the solar energy can be obtained in broad daylight, it cannot guarantee that the solar energy can accurately reach the required intensity value. The high-precision solar simulator can well simulate the intensity and spectrum of sunlight under stable conditions. The index to measure the solar simulator is: the similarity between the light source and the real sunlight. This indicator is mainly reflected in three aspects: spectral matching degree, uniformity of integrated intensity, and stability of optical radiation. [0003] The current solar simulator mainly uses xenon lamp as the light sour...
