Abstract

393,886. Electric lamp bulbs with internal reflectors. NAAMLOOZE VENNOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Jan. 6, 1933, No. 532. Convention date, Jan. 16, 1932. [Class 39 (ii).] In a multiple filament electric lamp for vehicles, wherein one filament 3 surrounded by a screen 4 has one end 7 secured to the screen and the other end 5 to a pole wire 6, the premature destruction of the filament 3 due to vibration is prevented by anchoring together the pole wire and. screen by rigid metal wires 8, 9 respectively secured thereto at one end and terminating in an intermediate insulator such as a glass bead 10. The main filament 2 is arranged substantially at the focus of a parabolic reflector 11.
