Wedge lead lamp
View Patent ↗A pin lead incandescent lamp may be adapted for use in wedge type sockets. Opposed planar faces may be attached to the pins, enabling coupling to corresponding socket faces. Resilient U shaped pieces may be welded to the pins providing a simple coupling with a secure spring or friction coupling to standard wedge type socket.
1. An incandescent lamp comprising:
a light transmissive envelope defining an enclosed volume; and having a press-sealed end;
a filament type light source positioned in the defined volume;
a first electrical lead passing through the press-sealed end, having a first end electrically coupled to the filament and having a second end extending along a first axis away from the press-seal, and exposed on the lamp exterior for electrical connection;
a second electrical lead passing through the press-sealed end, having a first end electrically coupled to the filament and having a second end extending along a second axis away from the press-seal, and exposed on the lamp exterior for electrical connection;
wherein the second end of the first lead includes a first contact face and a second contact face, the first contact face and the second contact face being offset one from the other and each being approximately parallel to each other and to the first lead axis; and
wherein the second end of the second lead includes a first contact face and a second contact face, the first contact face and the second contact face being offset one from the other and each being approximately parallel to each other and to the second lead.
2. The incandescent lamp in claim 1 , wherein the first contact face and the second contact face of at least the first lead are formed by flat sides of a conductive piece electrically coupled to the first lead.
3. The incandescent lamp in claim 1 , further including a reflector shell positioned around the lamp envelope to generally face the lamp envelope on a first side of the shell, and wherein the first lead and the second lead are exposed for electrical contact on a second side of the shell.
4. The incandescent lamp in claim 1 , wherein at least a portion of one contact face is resiliently extended away from the lead end with a gap intermediate the resilient portion and the lead end with no applied tension, and where by the resilient portion may be compressed towards the lead end with applied tension.
5. The incandescent lamp in claim 1 , further including a reflector shell positioned around the lamp envelope to generally face the lamp envelope on a first side of the shell, and wherein the first lead and the second lead are exposed for electrical contact on a second side of the shell; and
wherein at least a portion of one contact face is resiliently extended away from the lead end with a gap intermediate the resilient portion and the lead end with no applied tension, and where by the resilient portion may be compressed towards the lead end with applied tension.
6. An incandescent lamp comprising:
a light transmissive envelope defining an enclosed volume; and having a press-sealed end;
a filament type light source positioned in the defined volume;
a first electrical lead passing through the press-sealed end, having a first end electrically coupled to the filament and having a second end extending along a first axis away from the press-seal, and exposed on the lamp exterior for electrical connection;
a second electrical lead passing through the press-sealed end, having a first end electrically coupled to the filament and having a second end extending along a second axis away from the press-seal, and exposed on the lamp exterior for electrical connection;
wherein the second end of the first lead includes a resilient U shaped end with a first contact face and a second contact face, the first contact face and the second contact face being offset one from the other and each being approximately parallel to each other and to the first lead axis; and
wherein the second end of the second lead includes a resilient U shaped end with a first contact face and a second contact face, the first contact face and the second contact face being offset one from the other and each being approximately parallel to each other and to the second lead.
7. The incandescent lamp in claim 6 , wherein the first contact face and the second contact face of at least the first lead are formed by flat sides of a conductive piece electrically coupled to the first lead.
8. The incandescent lamp in claim 6 , further including a reflector shell positioned around the lamp envelope to generally face the lamp envelope on a first side of the shell, and wherein the first lead and the second lead are exposed for electrical contact on a second side of the shell.
9. The incandescent lamp in claim 6 , wherein at least a portion of one contact face is resiliently extended away from the lead end with a gap intermediate the resilient portion and the lead end with no applied tension, and where by the resilient portion may be compressed towards the lead end with applied tension.
10. The incandescent lamp in claim 6 , further including a reflector shell positioned around the lamp envelope to generally face the lamp envelope on a first side of the shell, and wherein the first lead and the second lead are exposed for electrical contact on a second side of the shell; and
wherein at least a portion of one contact face is resiliently extended away from the lead end with a gap intermediate the resilient portion and the lead end with no applied tension, and where by the resilient portion may be compressed towards the lead end with applied tension.
