Abstract
The present invention is directed to a device consisting of at least one occupancy sensor and relay switch for providing power to UVC germicidal light sources when the at least one sensor does detect the absence of a person or object in the room or space, and automatically turns off the UVC germicidal light sources when the at least one sensor does detect the presence of a person or object entering or already in a room or space. Additionally, the same device using the at least one sensor and relay switch can include general lighting white color light sources that energize automatically when the at least one sensor does detect the presence of a person or object in a room or space, and automatically turns off the general lighting white color light sources when the at least one sensor does detect the absence of a person or object in the room or space.
