Extruded lamp housings

Claim 2

A lamp housing comprising: a first plurality of external channel sections; a second plurality of internal baffle elements; and interlocking means on said sections and elements mateable for assembling said channel sections in mutually parallel spaced apart relationship to form a tubular structure having longitudinal ventilation slots between said channel sections.

Claim 3

The housing of claim 1 wherein said interlocking means comprise longitudinally extending bosses of a first gender on said channel sections and bosses of a second gender on said internal baffle elements.

Claim 4

The housing of claim 2 wherein said external channel sections are extrusions and said bosses of first gender are formed integrally therewith.

Claim 5

The housing of claim 3 wherein said internal baffle elements are extrusions with said bosses of second gender formed integrally therewith.

Claim 6

The housing of claim 3 wherein said internal baffle elements are plates apertured to define an air flow path through said tubular structure between said ventilation slots, said apertures being offset in relation to said ventilations slots so as to contain stray light emitted by a lamp mounted to one end of said tubular structure.

Claim 7

The housing of claim 5 wherein said plates are extrusions with said bosses of second gender formed integrally therewith.

Claim 8

The housing of claim 1 further comprising additional boss means on said external channel sections for interlocking with a carrier plate inserted between said internal baffle elements.

Claim 9

The housing of claim 7 further comprising a carrier plate engageable with said additional boss means for supporting power supply means such as a transformer within said tubular structure.

Claim 10

The housing of claim 1 further comprising a lamp holder baffle closing one end of said tubular structure and an end plate closing the opposite end thereof.

Claim 11

A lamp housing comprising: plurality of outer channel sections; internal light baffle means arranged between said outer channel sections; interlocking means on said outer sections and said baffle means for assembling said channel sections in mutually parallel spaced apart relationship forming a tubular structure with longitudinal ventilation slots between said channel sections; and apertures in said baffle means defining with said ventilation slots an air flow path through said tubular structure, said apertures being offset in relation to said ventilation slots so as to contain stray light emitted by a lamp mounted to one end of said tubular structure.

Claim 12

A lamp housing comprising: plurality of outer channel sections; internal light baffle means arranged between said outer channel sections; interlocking means on said outer sections and said baffle means for assembling said channel sections in mutually parallel spaced apart relationship forming a tubular structure with longitudinal ventilation slots between said channel sections; and apertures in said baffle means defining with said ventilation slots an air flow path through said tubular structure, said apertures being offset in relation to said ventilation slots so as to contain stray light emitted by a lamp mounted to one end of said tubular structure.

Claim 13

The housing of claim 10 wherein said interlocking means comprise longitudinally extending slidably meteable bosses on each of said outer channel sections and said inner light baffle means.

Claim 14

The housing of claim 11 wherein at least said outer channel sections are extrusions with said bosses formed integrally therewith.

Claim 15

The housing of claim 10 further comprising a lamp holder baffle closing one end of said tubular structure and an end plate closing the opposite end thereof.

Claim 16

The housing of claim 10 further comprising mounting means including clamp means, said clamp means being attacheable to the housing for supporting the housing in fixed relationship to said mounting means, said clamp means being releasable for sliding movement along one or more of said ventilation slots thereby to selectively position said mounting means at any point continuously along the housing.

Claim 17

The housing of claim 14 wherein said outer channel sections have grooved edges along each side of said ventilation slots and said clamp means are slidable within said grooves.

Claim 18

The housing of claim 13 wherein said inner baffles are configured to allow a lamp mounted to said lamp holder baffle to illuminate the inner surface of the lamp holder baffle which inner surface then reflects the light onto the outer surface of said inner baffles thereby achieving the visual effect of glowing accent stripes along said ventilation slots of the housing.
