  • Publication number: 20180180237
    Abstract: The invention refers to a dimming cap for a lamp with two separate radiation sources and, in particular, for a two-filament incandescent lamp, which has a concave shape with a base surface from which a circumferential side wall extends at least to a height H0 above the base surface, wherein the dimming cap, in a cross section formed at a height H0 parallel to the base surface, has a width (w0) that is constant within a tolerance of ±0.1 mm over a first longitudinal section of the dimming cap, and which decreases over a second longitudinal section extending from the first longitudinal section to a first end of the dimming cap, and the height of the sidewall corresponds within a tolerance of ±0.1 mm over the first longitudinal section to the constant height H0, wherein it increases over the second longitudinal section, wherein the first longitudinal section is between 70% and 98% of the length of the dimming cap in the cross-section formed at the height H0.

  • Patent number: 8415868
    Abstract: A lamp (10) for an automotive headlamp and a method for manufacturing such kind of a lamp (10) is provided, wherein the lamp (10) comprises a burner (12) for emitting light, a metal holder (20) connected to the burner (12) for supporting the burner (12), a first socket part (32) made from a heat-resistant plastic material, which is connected to the burner (12), and a second socket part (34), through which a part of the burner (12), which is connected to a first electrical pole (14), is led for connecting the burner (12) to a voltage source, wherein the second socket part (34) is arranged adjacent to the first socket part (32) such, that at least one insulating gap (42) for providing voltage resistance in mainly radial and/or axial direction is provided. Due to the first socket part (32) it is possible to receive the hot burner (12) by the socket without impairing the heat resistance, wherein the second socket part (34) may be made from a cheaper material.
