Abstract
A germicidal motion-detecting lighting system includes a plurality of lighting units configured to electrically connect to one another. Each modular lighting unit has an enclosure, having an enclosure, a light emission window positioned within a first cavity of the enclosure, and a plurality of light emitting diodes positioned within the first enclosure, at least one motion sensor that protrudes through a second cavity of the enclosure, and a processor positioned within the enclosure that detects motion of a user based on data received from the at least one motion sensor and generates an activation command to emit visible light based on the motion of the user. The plurality of light emitting diodes receives the command and emits visible light based on the command. One of the modular lighting units further includes an additional enclosure with a third cavity in which an additional light emission window is positioned to emit ultraviolet light via an additional plurality of light emitting diodes.
