Abstract
754,011. Tubular electric incandescent lamps. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 1, 1954 [April 4, 1953], No. 9582/54. Class 39(2). In order to prolong the useful life of the axially arranged filaments of electric lamps of the double capped tubular type, such as those used in the direction indicators of motor vehicles, the ends 5, 6 of the helical filament 1 are offset substantially at rightangles to the axis thereof and attached to end portions of leading-in conductors 2 which are inclined away from the longitudinal axis of the filament. In the example the opposite ends of the filament and the respective ends of the leading-in wires to which they are attached are offset and inclined in opposite directions. Alternatively the ends of the filament may be arranged parallel to one another in the same direction and the ends of the leading-in wires inclined accordingly for attachment thereto.
