Abstract
A lamp for automotive vehicle front lighting is described. The lampcomprises a basefor mechanical and electrical connection to an automotive headlightand a burnerfixed to the base. The burnercomprises an enclosed transparent vessel. A first and a second filamentare arranged within the vessel. A baffleis arranged proximate to the first filamentto shield the second filamentfrom the first filament. When the first filamentis 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. If the second filamentis 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. Both the first and the second filament wireare 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 filamentsis 16-23.
