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.
