A halogen bulb lamp assembly manufactured by mounting a previously aligned halogen bulb unit in a one-piece molded plastic rectangular reflector with a mirrorized paraboloidal inner surface. The halogen bulb unit has a pair of spaced connector pins that are coated with an epoxy adhesive and inserted into a pair of stepped through bores in the reflector. The pins are shaped to force epoxy uniformly into the larger portions of the reflector bores, and the ends of the pins project from the rear of the reflector and are spot welded to terminals that have barbed projections pressed into the rear of the reflector.

Arc tube and plastic reflector assembly method

A rectangular lamp unit and an integral bracket, replaceable as a unit upon bulb burn-out, including a one-piece plastic reflector closed by a rectangular lens with an integral peripheral mounting flange on the reflector adjacent the lens so that the unit can be mounted substantially flush on a mounting panel. The unit is manufactured by applying an epoxy adhesive to a lens recess in the reflector, joining the lens thereto, and then heating the assembly to cure the epoxy. During heating, evolved gases are released from the reflector through a vent hole that is sealed by a vent plug immediately after heating by inserting the plug coated with a silicone rubber sealant into the vent hole to form a thick seal ring and push sealant into irregularities in the hole. The sealant is cured by residual heat from the epoxy curing step.

Rectangular halogen lamp unit and method of manufacture

A self-housed rectangular lamp assembly with a replaceable halogen bulb lamp unit. A cup-shaped housing, having a pivotal mounting bracket, receives a lamp unit that has a pair of integral threaded bosses on its rear surface receiving fasteners extending through the rear of the housing to releasably attach the lamp unit within the housing.

Self-housed rectangular lamp assembly with a replaceable halogen bulb

A dual halogen bulb rectangular lamp assembly with a one-piece plastic reflector having two adjacent paraboloidal mirrorized inner surfaces. A halogen bulb unit is mounted in each of the mirrorized surfaces and they are electrically connected in series for simultaneous bulb energization.
