Abstract

A mountable multiple angle sanitizing light for a door handle with the ability to be powered by batteries or ac mains. Preferably, ultraviolet light is used to disinfect the particular area of the door handle. A motion detection system can also be incorporated to regulate safety procedures and for controlling a light shut-off time, time off, and light illumination time.

First claim

What is claimed is:

1. A system for sanitizing a fixture of a door, comprising:
a door having a front surface and a back surface;
a glass push plate fixture having an outer surface and a rear surface, said fixture secured to either said door front surface or said door back surface;
at least one ultraviolet light source positioned to illuminate through said glass push plate rear surface such that when activated the at least one ultraviolet light source provides ultraviolet light that is used directly or indirectly for sanitizing said fixture;
a motion sensor configured to detect movement in an area adjacent to said door and disable the at least one ultraviolet light source; and
a control and timing circuit in communication with the at least one ultraviolet light source and in communication with the motion sensor; the control and timing circuit programmed to receive information from the motion sensor when the motion sensor detects movement in the area and the control and timing circuit programmed to activate the at least one ultraviolet light source for a previously configured period of time when movement in the area has ceased; and
a power source for powering the control and timing circuit.

2. The system for sanitizing a fixture of said door of claim 1 wherein the power source is one or more replaceable batteries battery cell.

3. The system for sanitizing a fixture of said door of claim 1 wherein the power source is an AC current source in communication with a rectification circuit.

4. The system for sanitizing a fixture of said door of claim 1 wherein the ultraviolet light source is a germicidal bulb.

5. The system for sanitizing a handle or a fixture of said door of claim 1 including a handle secured to said glass push plate that is illuminated by the at least one ultraviolet light source when the ultraviolet light source is activated by the control and timing circuit.

6. The system for sanitizing a fixture of said door of claim 1 wherein the ultraviolet light source is a germicidal lamp.

7. A method for sanitizing a fixture of a door, comprising the steps of:
a. automatically detecting by a motion detector any motion made within a vicinity of a door;
b. triggering a signal to a control and timing circuit by the motion detector when motion is detected by the motion detector;
c. activating at least one ultraviolet light source by the control and timing circuit upon receipt of the signal from the motion detector; and
d. directly projecting ultraviolet light from the ultraviolet light source through a rear surface of a glass push plate of the door.

8. The method for sanitizing a fixture of said door of claim 7 , further comprising the step of programming the control and timing circuit with a specific period of time for the ultraviolet light source to be activated each time a triggering signal is received from the motion detector.

9. The method for sanitizing a fixture of said door of claim 8 , further comprising the step of deactivating the ultraviolet light source at and end of the specific period of time.
