摘要： The low beam filament (51) and the high beam filament (52) are disposed in such a positional relationship as the virtual image of the irradiated portion of the high beam filament (52) does not produce glaring light in the low beam light distribution pattern. As a result, it is made possible to effectively utilize near 100% of light incident on the reflecting surface (40) of a reflector (4) and to obtain good low beam light distribution pattern and high beam light distribution pattern.

摘要： A fourth lead wire (LW40), since arranged in a shading coverage, is prevented from exposure to the irradiation lights from a low-beam filament (51) by the effect of the shading function of a high-beam filament (52). The front end of a third support wire (SW3) in a semi-shading coverage, since bent to a curved surface, receives the irradiation lights from the low-beam filament (51) but with a minute area; and the light diffusion function of the bending curved surface acts thereupon. The lower end on the front end portion (SW20) of a second support wire (SW2), since positioned above the lower end of the low-beam filament (51), is prevented from appearing above a light-shade boundary line. In either use as a right-traffic light source bulb or as a left-traffic light source bulb, lights from the low-beam filament (51) and the high-beam filament (52) reach the reflecting surface (40) of a reflector (4) without passing through a rear-end sealed part of a glass envelop, eliminating optical-path changes in the rear-end sealed part, production of glare light, and light-distributional problems. This results in freedom from virtual image glare, so that a single light source bulb (5) can be used both as a left-traffic light source bulb and a right-traffic light source bulb.

摘要： The invention relates to a lamp for a motor vehicle headlight. According to the invention, a lamp with two coils is proposed which is capable of fulfilling widely differing functions, among them in particular future AFS lighting functions, in a flexible manner. The coils are arranged in parallel in longitudinal direction next to one another, not one behind the other. Means for screening off the light emitted by the coils in certain angular regions are arranged such that the regions illuminated by the coils - at least in the radiation directions relevant for the use in a reflector - overlap only slightly, preferably not at all.

摘要： Die Erfindung betrifft eine Glühlampe für einen Kraftfahrzeugscheinwerfer. Die Nebenwendel (2) ist derart angeordnet, dass in einer Projektionsebene, die senkrecht zur Referenzebene (B) angeordnet ist, die der Abblendkappe (4) zugewandte Kante (2a) des auf die Projektionsebene projizierten Abbildes der zweiten Glühwendel (2) über die gesamte Länge der zweiten Glühwendel (2) zwischen der Referenzachse (A) und der Abblendkappe (4) angeordnet ist, und die der Abblendkappe (4) zugewandte Kante (2a) des im Maßstab 1:1 auf die Projektionsebene projizierten Abbildes der zweiten Glühwendel (2) einen vorgegebenen Abstand zur Referenzachse (A) besitzt. Dadurch kann die Hell-Dunkel-Grenze für das Abblendlicht mit Hilfe der Kante (2a) des Nebenwendelabbildes (2) erzeugt werden.

摘要： Die Erfindung betrifft eine Glühlampe mit mindestens einer Glühwendel (3,4), die zur Erzeugung eines Fernlichtbündels (6,8) in einem Kraftfahrzeugscheinwerfer eingesetzt werden kann, mit dem zusätzlich die Funktion eines Tagfahrlichtbündels realisiert werden kann. Die Verwendung eines gedimmten Fernlichtes als energiesparendes Tagfahrlicht (DRL) hat den Nachteil einer ungeeigneten Lichtverteilung des Fernlichtes für die Funktion als Tagfahrlicht. Weiterhin müßte das Fernlicht zur Erfüllung der Anforderung an die maximale Lichtstärke des Tagfahrlichtes so sehr gedimmt werden, dass der Halogenkreislauf im Kolben (2) der Glühlampe nicht mehr aufrechterhalten werden kann. Daher kommt es zu Abschwärzungen an der Kolbeninnenseite und zu einer Verkürzung der Lebenszeit. Um eine Glühlampe zu schaffen, die eine verbesserte Realisierung einer Tagfahrlichtfunktion in einem Kraftfahrzeugscheinwerfer ermöglicht, wird eine Glühlampe mit wenigstens einer ersten Glühwendel (3) zur Erzeugung eines Fernlichtbündels (6) in einem Kraftfahrzeugscheinwerfer und wenigstens einer zweiten Glühwendel (4) zur Erzeugung eines Tagfahrlichtbündels (8) in einem Kraftfahrzeugscheinwerfer vorgeschlagen.

摘要翻译： 通过远光灯丝（52）的遮光功能的作用，防止由阴影覆盖层布置的第四引线（LW40）暴露于来自远光灯丝（51）的照射光。 由于弯曲到弯曲表面，半遮光覆盖层中的第三支撑线（SW3）的前端从远光灯丝51接收照射光，而是以微小的面积接收; 并且弯曲曲面的光漫射功能起作用。 第二支撑线（SW2）的前端部（SW20）上的下端位于远光灯丝51的下端以上，防止出现在遮光边界线的上方。 在用作右交通光源灯泡或作为左交通光源灯泡的场合中，来自远光灯丝（51）和远光灯丝（52）的光到达反射器的反射面（40） （4）不通过玻璃罩的后端密封部分，消除后端密封部分的光路变化，产生眩光，以及光分布问题。 这导致了虚拟图像眩光的自由度，使得单个光源灯泡（5）既可以用作左交通光源灯泡和右交通光源灯泡。

摘要： A lamp capsule for use in a vehicle headlamp includes a lamp envelope having a tubular portion. First and second spaced-apart filaments are mounted in the lamp envelope for emitting light when energized by electrical energy. The lamp capsule further includes one or more light-attenuating axial stripes on the lamp envelope. The axial stripes are positioned on the lamp envelope for blocking light emitted by the first filament and reflected by the second filament. The lamp capsule may further include light-attenuating rings at or near opposite ends of the lamp envelope for defining upper and lower boundaries of a clear region of the lamp envelope. A filament support structure may include support leads located in the plane of the filaments for limiting light blockage and stray reflections.

摘要： A lamp for automotive vehicle front lighting is described. The lamp 10 comprises a base 12 for mechanical and electrical connection to an automotive headlight 50 and a burner 14 fixed to the base 12. The burner 14 comprises an enclosed transparent vessel 22. A first and a second filament 34, 36 are arranged within the vessel 22. A baffle 40 is arranged proximate to the first filament 34 to shield the second filament 36 from the first filament 34. When the first filament 34 is operated at a supply voltage of 13.2 V at an electrical power greater than 35 W and less than or equal to 38 W, light with a luminous flux of 500-700 lm is emitted from the lamp 10. If the second filament 36 is operated at a supply voltage of 13.2 V at an electrical power greater than 35 W and less than or equal to 38 W, light with a luminous flux of 800-1,000 lm is emitted from the lamp 10. Both the first and the second filament wire 34, 36 are comprised of a filament wire wound in a winding structure around a filament axis, where the number of winding turns for each of first and second filaments 34, 36 is 16-23.
