Abstract

The present invention relates to lighting assemblies and more particularly to light emitting diode (LED) light bulbs comprising a support for one or more LED lenses, which can be used to position and support the lenses within the lamp housing and which facilitate assembly of the light bulbs during manufacturing.

Claims (21)

1. A light assembly comprising:

a housing;

a non-conductive substrate with an electrically conductive pathway;

one or more light emitting diodes (LEDs) operably connected to the pathway;

a lens for each LED comprising a conical exterior surface;

a lens support having conical recesses corresponding to the conical exterior surface of each lens for supporting the lenses; and

a cover plate for securing the lenses and lens support within the housing.

2. The light assembly according to claim 1 , wherein the lens support is of single-piece construction.

3. The light assembly according to claim 1 , wherein the lens support and corresponding lens are capable of slideable and releasable engagement.

4. The light assembly according to claim 1 comprising a heat sink as all or part of the housing and formed from polyamide or polyphenylene sulfide.

5. The light assembly according to claim 4 , wherein the heat sink comprises fins, ridges, troughs, or vents, or combinations thereof.

6. The light assembly according to claim 5 comprising fins arranged longitudinally along the housing from housing face to base.

7. The light assembly according to claim 6 comprising vents in the housing face alternating between fins.

8. The light assembly according to claim 5 comprising alternating ridges and troughs arranged circumferentially around all or a portion of the housing.

9. The light assembly according to claim 1 wherein the housing comprises or is in operable communication with a heat pipe for dissipating heat.

10. The light assembly according to claim 1 operably configured as an MR-16, PAR-16, PAR-20, PAR-30, or PAR-38 type bulb.

11. A light assembly according to claim 1 further comprising:

a heat sink comprising polyamide or polyphenylene sulfide formed with vents alternating between fins.

12. The light assembly according to claim 11 , wherein fins of the heat sink are arranged longitudinally along the housing.

13. The light assembly according to claim 11 , wherein the vents alternating between fins are arranged circumferentially around all or a portion of the housing.

14. The light assembly according to claim 11 , wherein the heat sink is operably configured as a portion of housing for an MR-16, PAR-16, PAR-20, PAR-30, or PAR-38 type bulb.
