Abstract

A multiple function LED night light with air-freshener includes an LED display unit with light-medium properties to allow light beams from LED(s) located at LED input-ends of the display unit to travel within the light-medium and be uniformly emitted through a surface of the display for even brightness without hot spots. A housing of the night light includes a slot, space, room to allow an air-freshener, an LED display, a sealed-unit and all related electric components including a heat element or fan device to be disposed within the night light housing to provide multiple functions in addition to those of a conventional night light.

Claims

1. A multiple function LED night light with air freshener, comprising:

a housing including at least one slot for installing an air freshener unit;

said housing further accommodating at least one light medium arranged to receive light beams from at least one LED through an input, and to distribute the light beams evenly over a surface of the medium to provide area illumination an appearance of uniform brightness over the surface;

said housing further accommodating circuitry for controlling illumination of said at least one LED and means for spreading a fragrance supplied by said air freshener unit; and

said housing further accommodating at least one prong means for connecting the circuitry to a wall outlet to provide power to the LED means for spreading a fragrance,

wherein said light medium is arranged to be mounted on said housing and said slot is formed between said light medium and a section of said housing such that said light medium defines one wall of said slot and said section of said housing defines a second wall of said slot, said slot accommodating said air freshener unit.

2. A multiple function LED night light with air freshener as claimed in claim 1, further comprising additional components selected from the group consisting of multiple receptacles, a motion sensor, additional LEDs for directional illumination, and a time delay to provide additional functions.

3. A multiple function LED night light with air freshener as claimed in claim 1, wherein said means for spreading a fragrance supplied by said air freshener unit is a heater element.

4. A multiple function LED night light with air freshener, comprising:

a housing;

circuitry in the housing for controlling at least one LED and prong means for supplying power from a wall outlet to said circuitry; and

a light medium unit arranged to receive light beams from said at least one LED through an input, and to distribute the light beams evenly over a surface of the medium to provide area illumination an appearance of uniform brightness over the surface,

wherein said light medium unit is arranged to be mounted on said housing and a slot is formed between said light medium unit and a section of said housing such that said light medium defines one wall of said slot and said section of said housing defines a second wall of said slot, said slot accommodating an air freshener unit.

5. A multiple function LED night light with air freshener as claimed in claim 4, said housing further accommodating circuitry for controlling illumination of said at least one LED and at least one heater element or fan device for spreading a fragrance supplied by said air freshener unit;

and said housing further accommodating at least one prong means for connecting the circuitry to a wall outlet to provide power to the LED and heater element or fan device.

6. A multiple function LED night light with air freshener as claimed in claim 4, wherein said housing includes a front housing and a back housing, and said light medium unit is situated between the front housing and the back housing, said light medium unit including decorative elements selected from the group consisting of a decorative shape, openings, windows, curvature, designs, stencils, drawings, and three-dimensional artwork on said surface.

7. A multiple function LED night light with air freshener as claimed in claim 4,

wherein said circuitry is sealed within a box made of a plastic material that meets a flammability safety standard,

wherein said housing, said light medium unit, and said air freshener are outside said sealed unit, and

wherein said housing is made of a material other than said plastic material.

8. A multiple function LED night light with air freshener as claimed in claim 4, wherein said prong means is fixed in said housing.

9. A multiple function LED night light with air freshener as claimed in claim 4, wherein said prong means is arranged to swivel.

10. A multiple function LED night light with air freshener as claimed in claim 4, further comprising additional components selected from the group consisting of multiple receptacles, a motion sensor, additional LEDs for directional illumination, a time delay, and a heater element to provide additional functions.

11. A multiple function LED night light with air freshener as claimed in claim 10, comprising said heater element for dispersing fragrance from said air freshener to a wide area.

12. A multiple function LED night light with air freshener as claimed in claim 4, wherein said air freshener unit includes a material selected from the group consisting of a gel, flowers, potpourri, dry plants, and a paper-type medium.

13. A multiple function LED night light with air freshener as claimed in claim 4, further comprising additional LEDs for providing illumination at multiple angles.

14. A multiple function LED night light with air freshener as claimed in claim 4, wherein said light medium is made of a material selected from the group consisting of plastic resin, poly, pottery, porcelain, PS, PP, PET, PVC, PC, and acrylic.
