1. An ultraviolet (UV) irradiation system comprising:
a light source having an optical axis, the light source including:
a support structure configured to be mounted on a ceiling with the optical axis of the light source oriented vertically downward;
one or more UV light emitting diodes (LEDs) disposed on a surface of the support structure and configured to emit UV light when electrically energized; and
a reflector secured to the support structure and arranged to form the UV light emitted by the one or more UV LEDs into a light distribution having more angle-integrated intensity in the angular range θTr to 90° relative to the optical axis than in the angular range 0° to θTr relative to the optical axis, where θTr is at least 55°;
wherein the reflector comprises a funnel-shaped reflective surface facing the support structure and having an apex positioned on the optical axis of the light source, the funnel-shaped reflective surface expanding with increasing distance from the support structure along the optical axis.
