ABSTRACT:
The invention provides a mechanism for retaining a bulb in position in a lamp holder of a reflector. The lamp holder comprises a circulat bearing surface for engagement by the flange of a bulb, and the mechanism comprises a spring clip pivotally mounted on one side of the lamp holder and having cranked legs adapted to bear against the bulb flange. The spring clip is adapted to engage a catch element on the opposite side of the lamp holder which comprises a lamp engageable by the end of the spring clip, which terminates in a catch. The catch element also incorporates a release ramp facing the catch. On fitting of the bulb, pressure on the spring clip towards the opening causes the clip to side over the ramp and engage the catch, thereby to secure the bulb. Removal of the bulb is acheived by pressure on the spring clip in the same direction, which causes the clip to slide over the release ramp and pass out of the catch element, thereby releasing the bulb.
