Abstract

A lighting system for dispensing units such as ice and water dispensers on refrigerators includes a paddle on a shaft for activating and deactivating the dispenser by force applied from a receptacle. The shaft is configured as a light tube. A light source is positioned above the shaft to supply light into the shaft and paddle in the non-deflected condition. A prism is provided to receive light from the light source when the paddle is depressed, and to redirect light from the light source towards a receptacle positioned for receiving ice or water dispensed by the dispenser.

Claims

1. A lighting system for a dispensing unit having an actuator connected to a dispenser to activate and deactivate the dispenser by depressing the actuator with a receptacle for receiving a product dispensed by said dispensing unit, said lighting system comprising:

a light source;

at least a portion of said actuator configured as a light tube and positioned in a non-depressed condition for receiving light from said light source; and

a target area of said actuator illuminated by light from within said portion configured as a light tube when in the non-depressed condition, said actuator being further configured such that in a depressed condition, said target area of said actuator is moved away from the light from said light source such that the light from said light source illuminates at least one of the receptacle and product dispensed by said dispensing unit.

2. The lighting of system of claim 1, said light source being an LED.

3. The lighting of system of claim 1, said actuator including a shaft configured as a light tube and positioned to receive light therein from said light source.

4. The lighting of system of claim 3, said actuator including a paddle at an end of said shaft, said paddle configured for illumination from within by light from said shaft.

5. The lighting system of claim 1, including a light director for redirecting light from said light source when said actuator is depressed.

6. The lighting system of claim 5, said light director being in fixed position.

7. The lighting of system of claim 5, said light source being an LED.

8. The lighting system of claim 5, said light director being a prism.

9. The lighting system of claim 5, said light director positioned and configured with respect to said light source for redirecting light from said light source toward an inner surface of the receptacle pressed against said actuator.

10. A dispensing unit comprising:

a dispenser;

an actuator having a shaft with a connected end operatively associated with said dispenser and a distal end configured as a paddle, said actuator operatively associated with said dispenser for activating and deactivating said dispenser by depressing and releasing said paddle, said shaft being configured as a light tube and said paddle being adapted for external illumination by light from within said paddle conducted through said shaft; and

a light source near said connected end of said actuator, said light source supplying light to said light tube when said actuator is in a non-depressed position, and said light source supplying light away from said actuator when said actuator is in a depressed position.

11. The dispensing unit of claim 10, including a light director for redirecting light from said light source when said paddle is depressed.

12. The dispensing unit of claim 11, said light director being in fixed position.

13. The dispensing unit of claim 11, said light director being a prism.

14. The dispensing unit of claim 11, said light source being an LED.

15. The dispensing unit of claim 10, said light source being an LED.

16. A dispensing unit comprising:

a dispenser;

an actuator operatively associated with said dispenser for activating and deactivating said dispenser by depressing and releasing said actuator;

a light source near said actuator, said light source positioned for illuminating said actuator, said actuator acting as a light tube transmission of light directly therethrough when said actuator is in a non-depressed position; and

a light director positioned for receiving and redirecting light from said light source when said actuator is depressed, said light director positioned so as to receives significant light from said light source only when said actuator has been depressed.

17. The dispensing unit of claim 16, said light director being a prism.
