Abstract

A light bulb (10) includes a translucent housing (12) and a base (24). The housing (12) includes a plurality of LEDs (14a, 14b, 14c, and 15) positioned so as to emit light through the housing (12). The base (24) is configured to mate with a light socket. The base (24) also includes a compartment (23) for receiving and securing a replaceable active ingredient cartridge (22), and an active ingredient dispenser (20) for emitting an active ingredient from the cartridge (22) when the cartridge (22) is secured in the compartment (23). A fluorescent light source (30) may also be provided in the housing (12) as a source of illumination.

Claims

1. A light device comprising:

a base comprising a male electrical connector for being received in a female light socket that connects to an electrical supply, the base being disposed between the connector and an illumination source,

the base supporting the illumination source which is selected from the group consisting of at least one white LED, a fluorescent light, a halogen light and a group of red, green and blue LEDs mixed to produce white light,

the base comprising an active ingredient dispenser disposed in the base, the active ingredient dispenser capable of emitting an active ingredient from the base.

2. The light device according to claim 1, wherein the base supports a plurality of light emitting diodes (LEDs),

the plurality of LEDs comprise at least one red LED, at least one green LED and at least one blue LED.

3. The light device according to claim 2, further comprising a controller for controlling the plurality of LEDs.

4. The light device according to claim 3, further comprising a memory for storing programs for operating the controller to produce lighting effects from the plurality of LEDs.

5. The light device according to claim 4, wherein the lighting effects include changing the color of light emitted from the light device.

6. The light device according to claim 1, further comprising an interface for changing operation of the device.

7. The light device according to claim 1, wherein the active ingredient dispenser comprises a recess for receiving an insert containing active ingredient.

8. The light device according to claim 7, wherein the active ingredient is impregnated in a gel.

9. The light device according to claim 8, wherein the insert comprises a replaceable cartridge containing the gel impregnated with the active ingredient.

10. The light device according to claim 1, wherein the active ingredient dispenser comprises a volatilization facilitator to facilitate volatilization of the active ingredient selected from the group consisting of a resistance heater, a piezoelectric activated atomizer and a fan.

11. The light device according to claim 10, wherein the active ingredient dispenser comprises a plurality of vents which facilitate airflow across the active ingredient.

12. The light device according to claim 2, wherein the base is connected to a light diffuser.

13. The light device according to claim 1, wherein the connector is a threaded connector for mating with a threaded light socket.

14. The light device according to claim 1, wherein the connector is configured to mate with a light socket for receiving one of an incandescent bulb, a halogen bulb, or a compact fluorescent light.

15. The light device according to claim 1, wherein the active ingredient is selected from the group consisting of a fragrance, an air sanitizer, an insecticide, an insect repellant and combinations thereof.

16. A light device comprising:

a base comprising a male electrical connector being received in a female light socket connecting to an electrical supply, the base being disposed between the connector and an illumination source,

the illumination source supported on the base and selected from the group consisting of at least one white LED, a compact fluorescent light (CFL), a halogen light and a group of red, green and blue LEDs mixed to produce white light,

the base comprising an active ingredient dispenser disposed in the base that dispenses an active ingredient when the active ingredient is provided therein; and

a control mechanism, by which the light device can be controlled to change an emission rate of the active ingredient and operate the illumination source.

17. The light device according to claim 16, wherein the base is connected to a light diffuser that covers the illumination source.

18. The light device according to claim 16, wherein the active ingredient is selected from the group consisting of a fragrance, an air sanitizer, an insecticide, an insect repellant and combinations thereof.

19. The light device according to claim 16, wherein the illumination source comprises a compact fluorescent light (CFL) supported on the base, and the light device further comprises a plurality of LEDs supported on the base, including LEDs of at least two different colors,

the control mechanism having a plurality of settings including a first setting that controls the CFL to produce substantially white light and a second setting that controls the plurality of LEDs to produce colored light, and

a user interface for switching the control mechanism between at least the first and second settings.

20. A light device comprising:

a base comprising a male electrical connector being received in a female light socket connecting to an electrical supply, the base being disposed between the connector and an illumination source, the base comprising an active ingredient dispenser;

the illumination source mounted on the base and selected form the group consisting of a compact fluorescent light (CFL), at least one white LED, a halogen light, and at least one group of red, green a blue LEDs mixed to produce white light;
