Abstract

Various designs of electronic lighting devices are disclosed. Contemplated electronic lighting devices comprise a housing, a base, and a light source holder. The housing comprises an internal cavity that typically houses the base and the light source holder. The base is configured to mate with the housing, and the light source holder is affixed to the base. Preferably, the light source holder is configured to receive a light source in an inclined position with respect to the housing, such that light from the light source is emitted through an aperture of the housing and onto a flame element to simulate a real candle light.

First claim

What is claimed is:

1. An electric lighting device, comprising:
a housing comprising an internal cavity and an aperture on an upper surface;
a printed circuit board (PCB) disposed within the internal cavity;
a light source holder comprising (i) a base and (ii) a stem that extends upwardly from the base, wherein the light source holder is disposed within the internal cavity, and wherein the light source holder is coupled to the PCB, such that the light source holder covers the PCB; and
wherein the light source holder is configured to receive a light source in an inclined position with respect to the housing, such that light from the light source is emitted through the aperture.

2. The lighting device of claim 1 , wherein the stem terminates at a first end, and wherein the first end comprises an elongated, inclined cylinder having opposing ends with an aperture at each end, and wherein one of the apertures is configured to receive the light source such that the light source holder supports the light source within the housing.

3. The lighting device of claim 1 , wherein the light source holder is configured to at least partially encompass the light source when the light source is inserted into the cylinder of the light source holder.

4. The lighting device of claim 3 , wherein the light source holder is further configured to receive a lens and maintain a predefined focal length between the lens and the light source.

5. The lighting device of claim 1 , further comprising:
a flame element at least partially disposed within the internal cavity; and
a support member configured to support the flame element and allow for movement of the flame element with respect to the support member.

6. The lighting device of claim 5 , wherein the flame element comprises a hollow interior and an aperture disposed on a sidewall of the flame element, and wherein the support member extends horizontally through the aperture, and wherein the support member is sized and dimensioned to extend into the aperture on the sidewall to suspend the flame element within the internal cavity and allow the flame element to move with respect to the support member.

7. The lighting device of claim 1 , wherein the base comprises a flat surface extending outwardly from the stem.

8. The lighting device of claim 1 , wherein the light source comprises a light-emitting diode (LED).

9. An electric lighting device, comprising:
a housing having an internal cavity;
a first surface configured to be inserted within the housing, wherein the first surface comprises at least three apertures;
a light source support affixed to the first surface, wherein the light source support comprises an elongated stem extending upwardly from the first surface;
wherein the light source support further comprises at least three legs extending outwardly from the elongated stem and wherein each of the legs comprises a downwardly extending peg that is configured to be inserted into one of the at least three apertures when the light source support is affixed to the first surface; and
wherein the light source support is configured to receive a light source in an inclined position with respect to the first surface.

10. The lighting device of claim 9 , wherein the first surface comprises a PCB.

11. The lighting device of claim 9 , wherein the first surface is configured to be coupled to, and disposed above, a PCB.

12. The lighting device of claim 9 , wherein the elongated stem terminates at a first end opposite of the first surface, and wherein the first end comprises an inclined, cylindrical body having first and second apertures, and wherein the first aperture is sized and dimensioned to receive the light source.

13. The lighting device of claim 9 , wherein the light source support is further configured to receive a lens, and maintain a predefined focal length between the lens and the light source when the light source is received within the cylindrical body.

14. The lighting device of claim 9 , wherein the elongated stem of the light source support comprises a first opening configured to receive a fastener, and wherein the first surface comprises a second opening, such that insertion of the fastener through the second opening into the first opening of the elongated stem affixes the light source support to the first surface.

15. The lighting device of claim 9 , wherein the light source support is further configured to support and maintain the light source in the inclined position with respect to the first surface, and wherein the light source support is further configured to receive a lens, and maintain a predefined focal length between the lens and the light source when the light source is inserted into the light source support.

16. The lighting device of claim 9 , further comprising:
a support member coupled to the housing; and
a flame element coupled to the support member, such that the flame element can move with respect to the support member.

17. The lighting device of claim 9 , wherein the light source comprises a light-emitting diode (LED).
