[0003] At the same time, the above-mentioned system also has certain limitations on the other hand, which cannot simulate the actual state of the sun more realistically: first, the light source cannot move in real time and the brightness cannot be changed generally; The distance between points cannot be adjusted at any time, and there are some environmental conditions that cannot simulate the atmosphere, such as poor air, airgel transparency, clouds, etc.
[0004] When used as a light source to detect the accuracy of the sun azimuth sensor, the above shortcomings are highlighted, which also causes difficulties in measurement

Embodiment Construction
[0020] Working principle: The movement of the sun observed on the earth is a two-dimensional movement. In addition to its size, color, and brightness changes, the position can be determined by two angles, namely, azimuth and elevation. In addition to the two angles, the factors that affect the size, color, and brightness of the observed sun include: the distance between the sun and the earth, atmospheric humidity, air difference, aerogel, and transparency, etc. The size of the solar observation image mainly depends on the distance between the sun and the earth and Bad breath. This device uses control data to simulate actual natural conditions by changing the distance between the light source and the observation point, the azimuth angle and elevation angle of the light source to the observation point, and compares the signal output of the sun azimuth sensor to achieve the accuracy of the sun azimuth sensor. for verification purposes. In addition, the circular shape of the sun'...

The invention discloses a simulation sun movement astronomical refraction correction and test LED light source apparatus. The apparatus comprises: a fixed plate; a horizontal rotary plate; a horizontal driver, which is used for controlling horizontal rotations of the horizontal rotary plate to simulate an azimuth change of the sun; a vertical shunt; a vertical driver, which is used for controlling vertical rotations of the vertical shunt to simulate a pitch angle change of the sun; a simulation LED light source device; a sun aspect sensor; and an atmospheric environment simulator, which is used for simulating meteorological conditions of weathers. The fixed plate and the horizontal rotary plate are connected smoothly and rotationally; the vertical shunt and the vertical driver are arranged on the horizontal rotary plate; the simulation LED light source device is arranged on the vertical shunt; and the horizontal driver is arranged on the fixed plate. Besides, a distance between the simulation LED light source device and the sun aspect sensor can be adjusted movably, so that a sun-earth distance and changes of sun visual sense sizes can be simulated, wherein the changes of sun visual sense sizes are caused by the astronomical refraction. According to the invention, an actual running state of the sun can be simulated realistically.
Description
technical field [0001] The invention relates to an LED light source device for simulating the movement of the sun and correcting and testing the air difference. Background technique [0002] The current sun simulation light source is mostly used for spectrum and radiation testing. The light source is mainly xenon lamp, which adopts large-area uniform illumination; it is used to test the parameters and efficiency of photoelectric conversion of solar photovoltaic devices such as solar panel components and corresponding sensors. The above light source system has the advantages of mature technology, relatively complete product series, relatively uniform illumination, relatively high optical power, good stability, and can simulate the luminous color temperature of the sun at the same time. [0003] At the same time, the above-mentioned system also has certain limitations on the other hand, and it cannot simulate the actual state of the sun more realistically: first, the light sou...
