Abstract
Abstract Improved mechanical stop means are provided for a sealed prefocused light source mount for a parabolic aluminized reflector (PAR) lamp and, in particular, to improved mechanical stop means for an all-plastic PAR lamp or a PAR lamp comprising a plastic reflector. The particular mount construction employed utilizes a plastic block having mating parts which define a cavity from which lead wires extend and which is filled with an elastomeric polymer providing both a leak-proof seal around the lead wires as well as a more reliable barrier to moisture leakage through the mount assembly. An exterior surface of said plastic block limits insertion of the assembled lamp unit into a conventional plug-in receptacle used to supply electrical power to the lamp.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
137 words
A reflector lamp with a prefocused light source mount for a light source having two lead wires extending therefrom and joined one each to metal lug members, said prefocused light source mount comprising a plastic block having mating parts defining a cavity for receiving said joined lead wires and with said mating parts comprising an inner container member which is fitted into an outer housing member and with said cavity in said block being filled with an elastomeric polymer to provide a leak-proof seal, wherein said metal lug members have a smooth surface permitting a plug-in receptacle used to supply electrical power to the lamp to be inserted so that the outermost surface of said inner container member in said plastic block provides a mechanical stop means when said plug-in receptacle is connected to said reflector lamp.
Claim 2
Dependent Claim
137 words
A reflector lamp with a prefocused light source mount for a light source having two lead wires extending therefrom and joined one each to metal lug members, said prefocused light source mount comprising a plastic block having mating parts defining a cavity for receiving said joined lead wires and with said mating parts comprising an inner container member which is fitted into an outer housing member and with said cavity in said block being filled with an elastomeric polymer to provide a leak-proof seal, wherein said metal lug members have a smooth surface permitting a plug-in receptacle used to supply electrical power to the lamp to be inserted so that the outermost surface of said inner container member in said plastic block provides a mechanical stop means when said plug-in receptacle is connected to said reflector lamp.
Claim 3
Dependent Claim
41 words
A prefocused light source mount as in claim 1 wherein the inner container member has a box-like form which is fitted into an outer box-like housing member and said box-like members are sealed together at the periphery of the inner member.
Claim 4
Dependent Claim
17 words
A prefocused light source mount as in claim 1 wherein the light source is a tungsten-halogen lamp.
Claim 5
Dependent Claim
25 words
A prefocused light source mount as in claim 1 wherein the light source is positioned with respect to a locating surface on the mount construction.
Claim 6
Dependent Claim
39 words
A reflector lamp having a lens, and a plastic reflector wherein the prefocused mount of claim 1 is sealed to receptacle means on the reflector permitting the light source to be positioned aproximately at the focus of said reflector.
Claim 7
Dependent Claim
29 words
A reflector lamp as in claim 5 wherein said receptacle means includes a locating surface as the means of positioning the light source at the focus of said reflector.
Claim 8
Dependent Claim
24 words
A reflector lamp as in claim 6 wherein the light source is also positioned with respect to a locating surface on the mount construction.
