Embodiment Construction

[0023] The present invention is further described below through the examples, but the examples will not constitute a limitation to the present invention.

[0024] Such as figure 1 , 2 The shown reflective solar simulator embodiment of the present invention includes a xenon lamp 4 with a lampshade, a chassis 1, a bracket 9, and two pieces of glass 10. The inner wall of the chassis 1 is a reflector, which is an aluminum plate, and the reflector is surfaced. Sandblasted and oxidized to enhance its diffuse reflection. A filter for adjusting the spectral composition of the output light is fixed at the front end of the xenon lampshade. The filter is coated, and a layer of BaSO which has little effect on the reflected light spectrum is coated on the internal reflective surface of the xenon lampshade. 4 coating.

[0025] The lower part of the cabinet 1 is a bucket-shaped body 2 made up of four reflecting plates with a large mouth upwards. These four reflecting plates form an angle ...

Abstract

The invention relates to a reflective solar simulator which comprises a xenon lamp (4) provided with a lampshade and a simulator box (1), wherein the inner walls of the simulator box (1) are reflecting plates; the lower part of the simulator box (1) is a funnel-shaped body (2) which comprises four reflecting plates, and the larger opening of the funnel-shaped body (2) is upward; a rectangular barrel body comprising four reflecting plates is arranged above the funnel-shaped body (2); the xenon lamp (4) is arranged in the center of the simulator box (1) and points at the bottom of the funnel-shaped body (2); and the bottom of the funnel-shaped body (2) is a protrusion (7) comprising two reflecting plates and having an upward tip. In the invention, a perpendicular incidence mode is changed into a reflection mode, the lower part of the simulator box (1) is the funnel-shaped body (2), the rectangular barrel body is arranged above the funnel-shaped body (2), the bottom of the funnel-shaped body (2) is a protrusion (7) comprising two reflecting plates and having an upward tip, performing the function of scattering so as to even the reflection. Thus, stimulated sun light of which the irradiance uniformity can meet relevant specification requirements is obtained in effective radiation ranges.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a solar simulator for simulating sunlight when testing solar products. Background technique [0002] The current solar simulators all use direct xenon lamps, and it is difficult to obtain the requirement of uniform irradiance within the effective radiation range of the solar simulator. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a reflective solar simulator, which can obtain simulated sunlight with uniform irradiance and satisfactory spectrum within the effective radiation range of the solar simulator. [0004] The solution adopted by the present invention for solving the above-mentioned problem is: [0005] A reflective solar simulator, which includes a xenon lamp with a lampshade, a casing, and the inner wall of the casing is a reflector; [0006] The lower part of the chassis is a bucket-shap...
