Title:
TEST LIGHTING SYSTEM AND METHOD FOR TESTING A QUALITY OF A PHOTOVOLTAIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/061225
Kind Code:
A3
Abstract:
The invention relates to a test lighting system (2) for testing a quality of a photovoltaic system (5). The test lighting system (2) comprises an artificial light source (27, 28), a primary optic (1, 1', 1'', 41) and a secondary optic (3) having a microlens array (19) implemented and aligned to each other so that the primary optic (1, 1', 1'', 41) collimates light (9) of the light source (27) within a predefined range of angle of incidence (α) and thereby uniformly illuminates an inlet side of the microlens array (19) of the secondary optic (3), and wherein the light (9') exiting from an outlet side of the microlens array (19) impinges on an illumination area within a defined test acceptance angle range and comprises uniform angle distribution. The invention further relates to a method for testing a quality of a photovoltaic system and a test device (80) having such a test lighting system (2).
