Abstract
Abstract A lamp unit (10) for being removably positioned within the rear opening (11) of an automobile headlight reflector (13). The unit (10) includes a plastic holder (19), an electric (e.g., tungsten halogen) lamp (30) having a filament structure (42) contained within the envelope (33) thereof, a clamp member (46) secured to the lamp's press-sealed end portion (47), and an insert member (48) located within a cavity (21) of the holder (19). The clamp member (46) includes a pair of curved flange portions (56,58) which engage and are secured (e.g., welded) to the outer, curved surface (59) of the insert member (48), thus facilitating alignment and positioning of the lamp (30) relative to the holder (19).

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
173 words
In a lamp unit for being removably positioned within an opening within the rear portion of an automobile headlight reflector wherein said lamp unit includes an electrically insulative holder for being positioned within said opening and defining a cavity therein and an electric lamp adapted for being positioned within said holder, said lamp including an envelope having a filament structure therein and at least two lead-in wires projecting from said envelope, said filament structure being oriented within said reflector of said automobile headlight when said holder is positioned within said opening, the improvement comprising: a clamp member secured about said envelope of said electric lamp at a precise location relative to said filament structure; and an insert member located at a predetermined, precise depth within said cavity of said insulative holder, said clamp member being aligned on a surface of said insert member and secured thereto such that said filament structure will be oriented within said reflector in a precise manner relative thereto when said insulative holder is positioned within said reflector opening.
Claim 2
Dependent Claim
173 words
In a lamp unit for being removably positioned within an opening within the rear portion of an automobile headlight reflector wherein said lamp unit includes an electrically insulative holder for being positioned within said opening and defining a cavity therein and an electric lamp adapted for being positioned within said holder, said lamp including an envelope having a filament structure therein and at least two lead-in wires projecting from said envelope, said filament structure being oriented within said reflector of said automobile headlight when said holder is positioned within said opening, the improvement comprising: a clamp member secured about said envelope of said electric lamp at a precise location relative to said filament structure; and an insert member located at a predetermined, precise depth within said cavity of said insulative holder, said clamp member being aligned on a surface of said insert member and secured thereto such that said filament structure will be oriented within said reflector in a precise manner relative thereto when said insulative holder is positioned within said reflector opening.
