Abstract

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 H_E 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.
