Abstract

A lighting device, comprising a shield element and at least a first light source, the first light source within a space defined by portions of the shield element, the shield element comprising at least one vent, the shield element blocking the first light source from direct view from locations outside the shield element. Also, a lighting device, comprising a shield element and at least a first light source, the shield element comprising regions that define an opening, the first light source within a space defined by portions of the shield element and the opening. Also, a shield element.

Claims

1. A lighting device, comprising:

a shield element; and

at least a first light source,

the first light source within a space defined by portions of the shield element,

the shield element comprising at least one vent through which gas can pass to exit from the space,

the shield element blocking the first light source from direct view from at least all locations outside the shield element that are to a first side of a plane extending through the first light source.

2. A lighting device as recited in claim 1, wherein outer surfaces of the shield element correspond to portions of a shape of an A lamp.

3. A lighting device as recited in claim 1, wherein at least part of the shield element is substantially transparent.

4. A lighting device as recited in claim 1, wherein the first light source is a solid state light emitter.

5. A lighting device as recited in claim 1, wherein the first light source is a light emitting diode.

6. A lighting device as recited in claim 1, wherein the plane extending through the first light source is an emission plane of the first light source.

7. A lighting device as recited in claim 1, wherein the lighting device further comprises at least one active cooling element.

8. A lighting device, comprising

a shield element;

and

at least a first light source,

the shield element comprising regions that define an opening,

the first light source within a space defined by portions of the shield element and the opening,

the shield element comprising at least one vent through which gas can pass to exit from the space,

the shield element blocking the first light source from direct view from at least all locations outside the shield element that are to a first side of a plane defined by at least portions of the opening.

9. A lighting device as recited in claim 8, wherein a substantial entirety of a periphery of the opening is parallel to the plane.

10. A lighting device as recited in claim 8, wherein outer surfaces of the shield element correspond to portions of a shape of an A lamp.

11. A lighting device as recited in claim 8, wherein at least part of the shield element is substantially transparent.

12. A lighting device as recited in claim 8, wherein the first light source is a solid state light emitter.

13. A lighting device as recited in claim 8, wherein the first light source is a light emitting diode.

14. A lighting device as recited in claim 8, wherein the plane defined by at least portions of the opening is substantially parallel to an emission plane of the first light source.

15. A lighting device as recited in claim 8, wherein the lighting device further comprises at least one active cooling element.

16. A shield element, comprising:

shield element regions that define a space; and

at least a first vent through which gas can pass to exit from the space and a second vent through which gas can pass to exit from the space,

the first vent substantially symmetrical with respect to a first axis,

the second vent substantially symmetrical with respect to the first axis.

17. A shield element as recited in claim 16, wherein:

the first vent comprises at least first and second vent portions, and

the second vent comprises at least third and fourth vent portions.

18. A shield element as recited in claim 16, wherein outer surfaces of the shield element correspond to portions of a shape or an A lamp.

19. A shield element as recited in claim 16, wherein at least part of the shield element is substantially transparent.
