Embodiment Construction

[0020] Please see figure 2 with image 3 , shows a schematic diagram of the artificial light source generator and its light-emitting group according to the first embodiment of the present invention. The artificial light source generator 2 of the present invention can be used indoors to simulate sunlight to test the solar cell module to obtain its relevant product characteristics, but it can be understood that the artificial light source generator 2 of the present invention can also be applied to other products that require place of light. The artificial light source generator 2 includes at least one light emitting group 3 and a projection plane 21 . see image 3 , the light emitting group 3 includes a light source 31 , a parabolic mirror 32 , a support base 33 , a first lens array 34 , a second lens array 35 and a filter 36 .

[0021] The light source 31 is used to generate light. In this embodiment, the light source 31 is a xenon lamp, which includes two terminal electr...

Abstract

The invention relates to an artificial light source generator which comprises at least one luminous set and a projecting plane, wherein each luminous set comprises a light source, a paraboloidal mirror, a supporting seat, a first lens array and a second lens array; the light sources are positioned at the focal points of the paraboloidal mirrors so as to ensure that light rays generated by the light sources are emitted out through the paraboloidal mirrors along a parallel direction; the supporting seats are sued for supporting the light sources; the first lens arrays are provided with a plurality of first lens units, and each lens unit is provided with a first focal distance; the second lens arrays are provided with a plurality of second lens units, and a distance between the second lens arrays and the first lens arrays is 0.5-1.5 times of the first focal distance; and the projecting plane is spaced by a proper distance with the luminous sets so as to ensure that all the light rays passing through each second lens unit cover the whole projecting plane, thus the projecting plane has good illumination uniformity.

Description

technical field [0001] The invention relates to an artificial light source generator, in particular to an artificial light source generator capable of simulating a large area of ​​natural light. Background technique [0002] As the issues of environmental protection and energy saving are getting more and more attention, solar cell modules are gradually developing vigorously. However, one of the major problems faced after the solar cell module is manufactured is testing. Since the natural light (sunlight) will be strong or weak during the day, it is unstable and cannot be controlled by human means, so it is usually not to move the manufactured solar cell module outside for testing, the general test method It uses artificial light sources indoors to simulate sunlight to obtain product characteristics related to solar cell modules. [0003] Conventional testing methods are, for example, the following two methods. The first way is to use a flash-type xenon lamp (FlashXenon La...
