摘要: The invention relates to a headlight for a vehicle, comprising a concave reflector and a lamp arranged within the reflector to reflect light from the lamp to create an illumination beam with a bright/dark boundary. The lamp comprises a transparent vessel including a longitudinal axis, at least a first and second filament arranged within the vessel. A baffle arranged proximate to the first filament, and comprising first and second upper side edges. The first filament is arranged above a plane including the upper side edges. A different plane is through the center of the first filament and is arranged perpendicular to the longitudinal axis. The upper side edges are arranged symmetrically to a baffle symmetry axis extending from the center of the first filament centrally between the upper side edges. The lamp is arranged within the reflector rotated around said longitudinal axis by a rotation angle of 2°-20°.

摘要: An LED lamp includes a lamp base for insertion into a reflector of an automotive front lighting assembly; a panel extending from the lamp base with a first vertical side facing into one half of the reflector and a second vertical side facing into the other half of the reflector; a primary light source including a set of LED dies on each vertical side of the panel; a two-part shield including a first shield half shielding the LED dies on the first vertical side of the panel and a second shield half shielding the LED dies on the second vertical side of the panel. The two-part shield essentially has the form of a shield in a functionally equivalent filament lamp for providing a low beam. A lighting arrangement includes such an LED lamp; a reflector to receive the lamp; and an electrical interface for connecting to a controller.
