Incandescent lamp e.g. H4 lamp, for motor vehicle headlight, has power supply lines arranged outside of heat flow of spiral-wound filaments rising in operation of lamp in installation position

摘要

The lamp has two power supply lines (2, 6) extending towards a longitudinal axis of the lamp. Spiral-wound filaments (8, 10) are contacted by the power supply lines. The power supply lines are arranged outside of a heat flow of the filaments rising in an operation of the lamp in an installation position. Longitudinal axes of the power supply lines (2, 6) and a power supply line (4), and the filaments run parallel to each other and to the longitudinal axis of the lamp. The filaments are arranged one behind the other and viewed in approximately toward the longitudinal axis of the lamp.
