Track lighting fixtures and application thereof

1. A track head for a track lighting system, the track head comprising:

a track mount;

a baseless light bulb assembly without a light bulb socket; and

a conduit extending from the track mount and coupling to the baseless light bulb assembly, the conduit comprising electrical leads extending therein and connecting with power circuitry of the baseless light bulb assembly.

2. The track head of claim 1 , wherein the baseless light bulb assembly comprises a bulb envelope enclosing a light source and the power circuitry.

3. The track head of claim 2 , wherein the conduit couples to the bulb envelope.

4. The track head of claim 3 , wherein the conduit couples to the bulb envelope via a rotatable joint.

5. The track head of claim 3 , wherein the electrical leads pass through the bulb envelope to connect with the power circuitry of the baseless light bulb assembly.

6. The track head of claim 1 , wherein the conduit is directionally adjustable.

7. The track head of claim 1 , wherein the conduit comprises segments coupled by one or more joints.

8. The track head of claim 7 , wherein the conduit comprises two or more segments that are movable relative to one another.

9. The track head of claim 1 , wherein the conduit has rotatable engagement with the track mount.

10. The track head of claim 2 , wherein the light source comprises one or more light emitting diodes.

11. The track head of claim 10 , wherein the electrical leads connect with driver circuitry within the bulb envelope.

12. The track head of claim 1 , wherein the bulb envelope has a shape selected from the group consisting of A series, E series, G series, P series, PS series, S series, T series, R series, BR series, ER series and PAR series.

13. The track head of claim 1 , wherein the conduit is permanently coupled to the baseless light bulb assembly.

14. The track head of claim 1 lacking a housing or gimbal for receiving the baseless light bulb assembly.

15. A method of making a track head of a track lighting system comprising:

providing a track mount;

extending a conduit from the track mount and coupling the conduit to a baseless light bulb assembly, the conduit comprising electrical leads extending therein and the baseless light bulb assembly being without a light bulb socket; and

connecting the electrical leads with power circuitry of the baseless light bulb assembly.

16. The method of claim 15 , wherein the baseless light bulb assembly comprises a bulb envelope enclosing a light source and the power circuitry.

17. The method of claim 16 , wherein the conduit couples to the bulb envelope.

18. The method of claim 17 , wherein the conduit couples to the bulb envelope via a rotatable joint.

19. The method of claim 16 , wherein the light source comprises one or more light emitting diodes.

20. The method of claim 19 , wherein the electrical leads pass through the bulb envelope to connect with driver circuitry within the bulb envelope.

21. The method of claim 15 , wherein the track head lacks a housing or gimbal for receiving the baseless light bulb assembly.

22. A track lighting system comprising:

one or more powered rails or powered monopoints;

a baseless light bulb assembly without a light bulb socket; and

one or more track heads, a track head comprising a track mount and a conduit extending from the track mount and coupling to the baseless light bulb assembly, the conduit comprising electrical leads extending therein and connecting with power circuitry of the baseless light bulb assembly.

23. The track lighting system of claim 22 , wherein the baseless light bulb assembly comprises a bulb envelop enclosing a light source and the power circuitry.

24. The track lighting system of claim 23 , wherein the conduit is coupled to the bulb envelope.

25. The track lighting system of claim 24 , wherein the electrical leads pass through the bulb envelope to connect with the power circuitry of the baseless light bulb assembly.
