(54) Title: SINGLE END HALOGEN INCANDESCENT BULB 



00 
00 



O 




(57) Abstract: A single end incandescent halogen 
bulb has an envelope (112) having a sealed cavity 
(114) containing a halide material, a pich or press 
seal (110) at one end, and a coiled wire filament 
(100) disposed in the sealed cavity (114). Filament 
legs (102, 104) comprise portions of the coiled wire 
filament (100) that have been drawn out straight so as 
to have a diameter which is approximately the same 
as a diameter of a wire from which filament (100) 
is formed. A first current supply (106) wire extends 
through the press seal (110) into the sealed cavity. 
This first wire (106) has a first clamp (1 18) formed at 
a terminal end thereof. The first clamp (118) clamps 
a first filament (102) leg to establish a first electrical 
connection and suspend the filament (100) in the 
sealed cavity (114). A second current supply wire 
(108) extends into and terminates within the press seal 
(110). This second wire (108) has a second clamp 
(116) which clamps a second filament leg (104) to 
establish a second electrical connection. The second 
clamp (1 16) is enclosed in the press seal (1 10).
