Abstract
1474037 Reflectors LUCAS ELECTRICAL Ltd 25 Oct 1974 [15 Nov 1973] 53030/74 Heading F4R A lamp, e.g. a vehicle headlamp, fog lamp or spot lamp, having a reflector comprising a dished body 11 moulded in a thermosetting resin and provided with a reflective coating on the inside surface, has two pairs of spaced projections 13, 14 integrally moulded with the body 11 and extending from the outer surface thereof, each pair of projections supporting a resilient member 17, 18 which, in use, securely mounts a bulbholder in an aperture 12 in the reflector. The resilient members 17, 18 have end portions which engage in apertures in the projections and intermediate looped portions 21 and are movable between positions which enable the bulbholder to be inserted or retained in position. The reflective coating of aluminium film may be provided on top of one or more base lacquer coatings of a polyester, epoxy or alkyd resin, and a further lacquer coating may be provided over the reflective layer. A specific composition of a thermosetting polyester including 12-18% by weight of glass fibre suitable for injection moulding is given. Two dished bodies may be provided in an integrally moulded side-by-side relationship, each body having the integral projections thereon.
