LAMP AND REFLECTOR UNIT

摘要

A unit of a lamp and a reflector in which the lamp is fixed with its first seal (14) in a neck-shaped portion (5) of a reflector body (1). At its rear end, the neck-shaped portion is provided with a ceramic lamp cap (20). A ring (58) is provided around the first seal for counteracting the flow of cement (19) from the neck-shaped portion into the reflective portion (2) during manufacture of the unit. A spiral (35) is provided around the first seal, which spiral exerts resilient pressure on the ring towards the ceramic lamp cap, thus keeping the ring in position. When made of electrically conducting material, the spiral simultaneously functions as an external antenna.
