METAL HALIDE LAMP FOR AUTOMOTIVE HEADLAMP AND HEADLAMP WITH SAID LAMP

摘要

A discharge lamp and a headlamp with a discharge lamp are described. The discharge lamp10 includes a discharge vessel16 with electrodes 20 for generating an electrical arc. The discharge vessel includes a filling with a rare gas and metal halides. In order to avoid inhomogeneities from scattering at a salt pool 22 within the discharge vessel, the lamp further comprises a diffusing portion 24 arranged such that at least a portion of light emitted below a horizontal is diffused, and that light emitted above the horizontal is not diffused. A headlamp comprises a reflector 32 with an upper reflector portion 36 reflecting light emitted above a horizontal and a lower reflector portion 38 reflecting light emitted below. The diffusing portion 24 is arranged such that at least a portion of light reflected at the lower reflector portion 38 is diffused, and that light reflected at the upper reflector portion 36 is not diffused.
