摘要： The invention relates to an incandescent lamp for a motor vehicle headlight. The secondary filament (2) is arranged in such a way that, in a projection plane that is arranged perpendicular to the reference plane (B), the edge (2a), facing the antidazzle device (4), of the image, projected onto the projection plane, of the second incandescent filament (2) is arranged over the entire length of the second incandescent filament (2) between the reference axis (A) and the antidazzle device (4), and the edge (2a), facing the antidazzle device (4), of the image, projected to the scale 1:1 onto the projection plane, of the second incandescent filament (2) has a prescribed spacing from the reference axis (A). It is thereby possible to produce the light/dark boundary for the lower beam with the aid of the edge (2a) of the secondary filament image (2).

摘要： The invention relates to an incandescent lamp for motor vehicle headlights, having at least one incandescent filament (2) arranged inside the lamp vessel, and a shading device (4). A coil exit (2a) of the incandescent filament (2) is joined to an edge section (41) of the shading device (4) running substantially parallel to the coil axis, in order to ensure an improved suspension of the incandescent filament (2).

摘要： The invention relates to a halogen incandescent lamp for motor vehicle headlamps with two incandescent filaments (21, 22), which are arranged within a lamp vessel (10), wherein a first incandescent filament (21) is designed for operation with a higher electrical power than the second incandescent filament (22), wherein the incandescent filaments (21, 22) are constructed in such a way that their dimensions and/or their geometry are in each case matched to an operating voltage of at least 20 volts, and at least the second incandescent filament (22) is an incandescent filament in the form of a single coil. Preferably, both incandescent filaments (21, 22) are in the form of incandescent filaments with a single coil, wherein the first incandescent filament (21) is used, for example, for producing the upper beam or lower beam and the second incandescent filament (22) is used for producing the daytime driving light or foglight.

摘要： The invention relates to an electric incandescent lamp, in particular a vehicle headlight, having at least one incandescent filament which is arranged within a light-permeable lamp vessel, the at least one incandescent filament having different pitch factors at its two ends. In order to increase the luminance at the light/dark boundary of the lower beam, that end of the incandescent filament which is near to the base has a lower pitch factor.
摘要翻译：本发明涉及一种电白炽灯，特别是车辆头灯，其具有布置在透光灯容器内的至少一个白炽灯丝，所述至少一个白炽灯丝在其两端具有不同的螺距因子。为了增加下光束的亮/暗边界处的亮度，靠近基座的白炽灯丝的端部具有较低的螺距系数。
