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 bulb comprising:

a translucent housing comprising an open bottom;

the open bottom of the housing being connected to a base;

the base being connected to a connector for mating with a light socket, the base being disposed between the housing and the connector;

a plurality of LEDs positioned within the housing so as to emit light through the housing and the LEDs being supported by at least one of housing or the base;

an active ingredient dispenser disposed in the base, the active ingredient dispenser comprising a compartment for receiving and securing a replaceable active ingredient cartridge within the base, the active ingredient dispenser being capable of emitting an active ingredient from the cartridge and out the base when the cartridge is secured in the compartment.

2. The light bulb according to claim 1, wherein the plurality of LEDs include different color LEDs.

3. The light bulb according to claim 2, further comprising a controller for altering the color of light emitted through the housing by the plurality of LEDs.

4. The light bulb according to claim 2, further comprising a microprocessor for controlling the plurality of LEDs to emit light of different colors based on a user'"'"'s input.

5. The light bulb according to claim 4, further comprising a memory for storing programs for operating the microprocessor to produce different predetermined lighting effects.

6. The light bulb according to claim 5, wherein at least one of the lighting effects includes automatically changing the color of light emitted from the housing over time.

7. The light bulb according to claim 5, further comprising an interface, which the user operates to change between the different programs stored in the memory.

8. The light bulb according to claim 2, wherein the housing comprises a non-fluorescent light diffuser.

9. The light bulb according to claim 1, wherein the compartment is configured to receive a cartridge in which the active ingredient is impregnated in a gel.

10. The light bulb according to claim 1, wherein the compartment is configured to receive a cartridge formed as a reservoir holding an oil containing the active ingredient.

11. The light bulb according to claim 1, wherein the dispenser is a heater that heats the active ingredient to facilitate evaporation of the active ingredient.

12. The light bulb according to claim 1, wherein the dispenser comprises a plurality of vents which facilitate airflow across the cartridge when the cartridge is mounted therein.

13. The light bulb according to claim 1, wherein the base has a threaded connector for mating with a threaded light socket.

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

15. The light bulb according to claim 1, wherein the active ingredient in the active ingredient cartridge is a fragrance.

16. The light bulb according to claim 1, wherein the active ingredient in the active ingredient cartridge is selected from the group consisting of a sanitizer, an insecticide, and an insect repellant.

17. The light bulb according to claim 1, further comprising a fluorescent light source positioned in the translucent housing.

18. A light bulb comprising:

a base disposed between a connector configured to mate with a light socket for receiving the light bulb and a translucent bulbous housing;

a plurality of LEDs, including LEDs of at least two different colors, coupled to the base and extending at least partially into the housing;

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

a control mechanism, by which the light bulb can be controlled by a user to change at least one of a color of light emitted horn the housing by the plurality of LEDs, and an output rate of the active ingredient.

19. A light bulb according to claim 18, further comprising a fluorescent light source coupled to the base within the housing.

20. A light bulb according to claim 19, further comprising:

a control mechanism having a first setting that controls the fluorescent light source to produce substantially white light, and a second setting that controls the plurality of LEDs to produce colored light; and

a user interface, by which a user can cause the control mechanism to switch between the first setting and the second setting.
