Abstract

A dual lighting system including an LED illuminator, a lamp positioned in proximity to the LED illuminator. It also includes a motion sensor for detecting motion around the lighting system, a manual switch, and a control system which is coupled to the manual switch, the motion sensor, the lamp, and the LED illuminator. When the manual switch is activated, the control system is configured to turn on the lamp. If the motion sensor no longer detects motion around the dual lighting system, the control system is configured to turn off the lamp.

Claims

1. A dual lighting system, comprising:

an LED illuminator;

a lamp positioned in proximity to the LED illuminator;

a motion sensor for detecting motion around the lighting system;

a manual switch; and

a control system coupled to the manual switch, the motion sensor, the lamp, and the LED illuminator;

wherein when the manual switch is activated, the control system is configured to turn on the lamp; and

wherein if the motion sensor no longer detects motion around the dual lighting system, the control system is configured to turn off the lamp.

2. The dual lighting system of claim 1, wherein the LED illuminator is always on.

3. The dual lighting system of claim 1, wherein if the motion sensor no longer detects motion around the lighting system for a pre-specified amount of time, the control system turns off the lamp.

4. The dual lighting system of claim 3, wherein when the control system turns off the lamp, the control system also turns on the LED illuminator.

5. The dual lighting system of claim 1, wherein the manual switch is a momentary-off switch.

6. The dual lighting system of claim 1, wherein when the lamp is on, activating the manual switch causes the control system to turn off the lamp, and to turn on the LED illuminator.

7. The dual lighting system of claim 1, further comprising a battery-backup module for the LED illuminator, wherein the battery backup module provides power to the LED illuminator if there is a power outage.

8. The dual lighting system of claim 7, wherein the battery backup module uses rechargeable batteries which recharge when power is supplied to the dual lighting system.

9. The dual lighting system of claim 1, wherein the LED illuminator is oriented to provide indirect light by pointing toward the ceiling or toward a wall.

10. The dual lighting system of claim 1, wherein the lamp is:

an incandescent lamp;

a halogen lamp;

a fluorescent lamp;

or

a second LED illuminator.

11. The dual lighting system of claim 1, wherein the dual lighting system is part of an indoor lighting fixture.

12. The dual lighting system of claim 1, wherein the dual lighting system is part of an outdoor lighting fixture.

13. The dual lighting system of claim 1, further comprising:

a light sensor which senses lighting level;

wherein if the room in which the dual lighting system is located is dark and if the motion sensor detects motion around the dual lighting system, the control system is configured to turn on the lamp.

14. The dual lighting system of claim 13, wherein the control system receives a lighting level reported by the light sensor and adjusts the brightness of the lamp to reach a pre-specified lighting level.

15. The dual lighting system of claim 1,

wherein if the motion sensor detects motion around the dual lighting system, the control system is configured to turn on the lamp;

and

wherein if the motion sensor no longer detects motion around the dual lighting system, the control system is configured to turn off the lamp, thereby providing an automatic-on and an automatic-off dual lighting system.

16. The dual lighting system of claim 15, wherein if the motion sensor no longer detects motion around the lighting system for a pre-specified amount of time, the control system turns off the lamp.
