Ultraviolet light exposure chamber for photovoltaic modules
An apparatus for performing UV light exposure testing of solar panels, also known as PV modules, with superior exposure uniformity, equipment throughput, and floor space requirements, consisting of a chamber including a plurality of UV lamps in a lamp array, at least one target plane, and reflective panels positioned within the chamber to redirect UV light to the target plane(s).
1. An apparatus for sing photovoltaic (PV) modules to ultraviolet light, comprising:
a vertically oriented lamp array, said lamp array comprised of a plurality of ultraviolet (UV) light sources;
at least one vertically oriented target plane; and
at least one reflector, said at least one reflector oriented to direct UV light from said lamp array to said at least one target plane, wherein the distance from at least one of said at least one reflectors to the light emitting portion of the nearest UV light source or group of UV light sources is at most one half the spacing between said UV light sources.
2. An apparatus for sing photovoltaic (PV) modules to ultraviolet light, comprising:
a vertically oriented lamp array, said lamp array comprised of a plurality of ultraviolet (UV) light sources;
at least one vertically oriented target plane; and
at least one reflector, said at least one reflector oriented to direct UV light from said lamp array to said at least one target plane, wherein the position of said UV light sources near the edge of said lamp array is closer to said at least one target plane than the position of said UV light sources near the center of said lamp array to provide enhanced exposure uniformity on said at least one target plane.
3. An apparatus for sing photovoltaic (PV) modules to ultraviolet light, comprising:
a vertically oriented lamp array, said lamp array comprised of a plurality of ultraviolet (UV) light sources;
at least one vertically oriented target plane;
at least one reflector, said at least one reflector oriented to direct UV light from said lamp array to said at least one target plane; and
one or more opaque light shields, said one or more opaque light shields disposed between said lamp array and said at least one target plane such that the intensity of said UV light is more uniform across said at least one target plane, wherein any one or more of the size, shape, and position of said one or more opaque light shields is automatically adjusted.
