ABSTRACT:
A trough-shaped reflector for use with rod-shaped sources of ultraviolet radiation in sunlamps has a rear wall behind the source and two side walls which flank the source and define therewith two narrow gaps. The front portions of the side walls are parallel to each other and extend forwardly beyond the source. The front surface of the rear wall has two concave portions which reflect rays into the respective gaps, and the rear portions of the side walls have parallel, zig-zag shaped or concave inner surfaces. The reflector can be made of a rectangular blank of sheet metal by imparting to the median portion of the blank a semicylindrical shape, by notching the outer side of the median portion midway between the marginal portions of the resulting preform, and by notching the inner side of the median portion at both sides of the notch in the outer side.
