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. The baffle 40 is of concave shape and includes a bottom surface 41 and side surfaces 45 terminating in side edges 48. The baffle 40 further includes a front surface 43 arranged between the first and second filaments 34, 36 to shield the second filament 36 from light emitted from the first filament 34. The side edges 48 each comprise a central portion 54 extending, in side view, straight and in parallel to the longitudinal axis X. The straight central portions 54 have an axial length of at least 3.5 mm. An edge height HE is defined as a distance between the bottom surface 41 and the plane defined between the central portions 54 of the side edges 48. The edge height is more than 2.8 mm.

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 supply voltage of 13.2 V at an electrical power greater 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 800-1000 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 said first and second filaments (34, 36) is (16-23).

摘要： A lamp for automotive front lighting and a vehicle headlight comprising the lamp are described, as well as a method of manufacturing the lamp. The lamp 10 comprises a base 12 for mechanical and electrical connection to an automotive headlight 50. A burner 14 is fixed to the base 12 and comprises a sealed transparent vessel 22. A first filament 34 is arranged within the vessel 22. A holding wire 30c is arranged within the vessel, and a baffle 40 is arranged proximate to the first filament 34 to partially shield light emitted from the first filament 34. The baffle 40 is fixed to the holding wire 30c. The transparent vessel 22 comprises a vessel wall including a cylindrical portion 24 surrounding the first filament 34. In order to obtain a lamp which may withstand vibration, a support member 38, 138, 238 is provided including at least a first part 39 fixed to the baffle 40 or to the holding wire 30c and a second part 43 which is in contact with the cylindrical portion of the vessel 22. The support member 38, 138, 238 comprises a flexible intermediate part 37 connecting the first and second parts, such that the baffle 40 or the holding wire 30c is supported resiliently against the vessel 22.
