Abstract
Abstract A bulbholder which is intended for accurately positioning a filament of a bulb, particularly a quartz halogen bulb, relative to a lamp reflector comprises a sheet metal body which receives a base of the bulb. A plurality of deformable legs in the form of loops serve to connect the body with a pair of flanges on opposite sides of the body. The flanges are fixed to a support and accurate positioning of the bulb filament is effected by moving the body relative to the flanges as permitted by deformation of the legs. In one embodiment, the flanges are apertured and are rivetted to a ceramic support. In another embodiment, the flanges have arcuate lipped edges which are brazed to an annular surface on the support.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
89 words
A bulbholder comprising a body adapted to receive a base of a bulb, at least one flange for mounting said body on a support, and a plurality of deformable legs connecting said flange with said body, said legs serving to support said body on said flange and being deformable to enable said body to be adjusted in more than one direction relative to said flange for bulb filament orientation purposes, and said legs holding said body in the required position relative to said flange after deformation of said legs.
Claim 2
Dependent Claim
89 words
A bulbholder comprising a body adapted to receive a base of a bulb, at least one flange for mounting said body on a support, and a plurality of deformable legs connecting said flange with said body, said legs serving to support said body on said flange and being deformable to enable said body to be adjusted in more than one direction relative to said flange for bulb filament orientation purposes, and said legs holding said body in the required position relative to said flange after deformation of said legs.
Claim 3
Dependent Claim
45 words
The bulbholder according to claim 1, wherein said flange extends laterally of said body and said legs are in the form of loops whereby the position of said body relative to said flange can be adjusted axially and angularly by appropriate deformation of said loops.
Claim 4
Dependent Claim
15 words
The bulbholder according to claim 1, wherein said flange is formed integrally with said legs.
Claim 5
Dependent Claim
50 words
The bulbholder according to claim 1, further comprising a projection at the end of said body opposite that into which the bulb base is inserted, said projection being adapted to engage a lead wire extending from the base of the bulb to hold said bulb against disengagement from said body.
Claim 6
Dependent Claim
37 words
The bulbholder according to claim 1, wherein said flange has a surface extending transversely with respect to said body, said surface being engaged, in use, against a surface of said support and secured thereto by securing means.
Claim 7
Dependent Claim
37 words
The bulbholder according to claim 1, wherein said flange has an arcuate, lipped edge remote from said legs, and said flange is disposed, in use, with said arcuate lipped edge engaging an annular surface of said support.
