Abstract
Abstract The invention relates to a construction of a lamp/reflector unit which is simple and which permits of connecting the light bulb in an aligned position very rapidly. For that purpose the light bulb has a metal support plate to which are fixed metal support pins by means of respective metal flanges. After the light bulb has been adjusted to a defined position with respect to the metal support pins, the metal support plate is secured to the metal flanges by soldering or welding.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
200 words
A lamp/reflector unit having a concave reflector member and a lens member attached thereto, a light bulb supported in spaced relation to the reflecting surface of said reflector member, said light bulb having a pinch seal at one end thereof from which current conductors emanate which are in electrical contact with a filament disposed within said light bulb, said pinch seal extending through and being secured to a metal support plate to which metal support pins are attached in a mutually electrically insulating manner, which pins extend from the plate in a direction opposite to that of the light bulb, each of said current conductors being secured to a respective support pin, said concave reflector member having near its apex mutually electrically insulated contact members, each of said support pins being attached to a respective contact member, each of said support pins being provided with a metal flange a maximum of one pin being in electrical contact with the respective metal flange, the other ones being electrically separated from their respective flange by an insulator, said metal flanges being rigidly attached to the metal support plate by a joint, selected from the group consisting of welded joints and soldered joints.
Claim 2
Dependent Claim
200 words
A lamp/reflector unit having a concave reflector member and a lens member attached thereto, a light bulb supported in spaced relation to the reflecting surface of said reflector member, said light bulb having a pinch seal at one end thereof from which current conductors emanate which are in electrical contact with a filament disposed within said light bulb, said pinch seal extending through and being secured to a metal support plate to which metal support pins are attached in a mutually electrically insulating manner, which pins extend from the plate in a direction opposite to that of the light bulb, each of said current conductors being secured to a respective support pin, said concave reflector member having near its apex mutually electrically insulated contact members, each of said support pins being attached to a respective contact member, each of said support pins being provided with a metal flange a maximum of one pin being in electrical contact with the respective metal flange, the other ones being electrically separated from their respective flange by an insulator, said metal flanges being rigidly attached to the metal support plate by a joint, selected from the group consisting of welded joints and soldered joints.
