Problems solved by technology

For example, the Sol3A solar simulator (refractive type) of the newport company in the United States has a maximum irradiation area of ​​only 203mm*203mm, and the price is extremely expensive (80,000 US dollars).
At the same time, there are also some reflective concentrators, such as the reflective solar simulator described in the application number 201010161147.0, because its light source occupies the center position, and because the light source is not a point light source, the parallelism and uniformity of the emitted light sex is hard to guarantee

Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0012] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0013] Such as figure 1 and 2 As shown, a solar simulator includes a light source 1, an ellipsoidal reflector 2 and a parabolic reflector 3, the light source 1 is arranged at the focal point A of the ellipsoidal reflector 2 and its irradiation direction is toward the ellipsoidal reflector 2, The focus B of the ellipsoid reflector 2 coincides with the focus C of the parabola reflector 3, and a filter 4 is arranged in front of the light source 1, and the light of the light source 1 passes through ...

Abstract

The invention discloses a solar simulator. The solar simulator comprises a light source, an ellipsoidal reflection mirror and a paraboloidal reflection mirror. The light source is arranged on the focal point A of the ellipsoidal reflection mirror, and the irradiation direction of the light source faces the ellipsoidal reflection mirror. The focal point B of the ellipsoidal reflection mirror coincides with the focal point C of the paraboloidal reflection mirror. Light of the light source irradiates the paraboloidal reflection mirror through the focal point B of the ellipsoidal reflection mirror after being reflected by the ellipsoidal reflection mirror and then exits in parallel after being reflected by the paraboloidal reflection mirror. The light source and the ellipsoidal reflection mirror are arranged outside the range of the light exiting in parallel after the light is reflected by the paraboloidal reflection mirror. The off-axis design is adopted in the solar simulator, firstly the light source becomes a point light source, then a reflection element is used, so that the exiting light is parallel and uniform, the total reflection structure is adopted, the cost is low, and a large-caliber parallel light source can be manufactured for meeting the test requirement of a light condensation assembly.

Description

technical field [0001] The invention belongs to the technical field of solar energy, in particular to a solar simulator. Background technique [0002] At present, there is no suitable solar simulator for the measurement of concentrated photovoltaic modules. For example, the Sol3A solar simulator (refractive type) of Newport Company in the United States has a maximum irradiated area of ​​only 203mm*203mm, and the price is extremely expensive (80,000 US dollars). At the same time, there are also some reflective concentrators, such as the reflective solar simulator described in the application number 201010161147.0, because its light source occupies the center position, and because the light source is not a point light source, the parallelism and uniformity of the emitted light Sex is hard to guarantee. Contents of the invention [0003] The object of the present invention is to provide a solar simulator capable of ensuring higher parallelism and uniformity of emitted light...
