View Patent ↗A lamp ( 50 ) has a lamp envelope ( 10 ) having a body ( 12 ) with a bottom ( 14 ) having a lead-in accepting channel ( 18 ); a seat ( 22 ) formed with the bottom ( 14 ) adjacent one of the lead-in accepting channels; a light source capsule ( 51 ) having two electrical lead-ins ( 52, 54 ) extending therefrom and through the lead-in accepting channel ( 18 ; and an electrical contact ( 24 ) having a first depending leg ( 26 ), an intermediate transverse portion ( 28 ) including a seat engager ( 30 ) adapted to cooperate with the seat ( 22 ), and a projecting leg ( 32 ) extending away from the intermediate transverse portion ( 28 ) and along a side ( 34 ) of the bottom ( 16 ), the first depending leg ( 26 ) being in mechanical and electrical contact with one of the lead-ins ( 54 ).
1. A lamp envelope comprising a body having a base, said base comprising:
a bottom having a channel;
a seat formed with said bottom adjacent said channel, said seat comprising a dimple formed in said bottom;
an electrical contact having a first depending leg;
an intermediate transverse portion including a seat engager engaging said seat, said seat engager comprising a boss that fits into said dimple, and
a projecting leg extending away from said intermediate transverse portion and along a side of said bottom.
2. The lamp envelope of claim 1 wherein a terminus of said projecting leg is formed with a reentrant portion.
3. The lamp envelope of claim 2 wherein said base has a pair of electrical contacts insulated from each other and said terminus of said projecting leg makes electrical connection with one of said electrical contacts.
4. The lamp envelope of claim 3 wherein said electrical contact that is connected to said terminus of said projecting leg is threaded.
5. A lamp comprising:
a lamp envelope having a body with a lamp base, said lamp base comprising:
a bottom having a channel;
a seat formed with said bottom adjacent said channel, said seat comprising a dimple formed in said bottom;
a light source capsule having a capsule base, said base being received in said channel and having two electrical lead-ins extending therefrom and through said channel; and
an electrical contact having a first depending leg, an intermediate transverse portion including a seat engager, said seat engager comprising a boss that fits into said dimple and adapted to cooperate with said seat, and a projecting leg extending away from said intermediate transverse portion and along a side of said bottom, said first depending leg being in mechanical and electrical contact with one of said lead-ins.
6. The lamp of claim 5 wherein a terminus of said projecting leg is formed with a reentrant portion.
7. The lamp of claim 6 wherein said lamp base has a pair of electrical contacts insulated from each other and said terminus of said projecting leg makes electrical connection with one of said electrical contacts.
8. The lamp of claim 7 wherein said electrical contact that is connected to said terminus of said projecting leg is threaded.
