3200796 Discloses dimmer lights comprising screen for the incandescence of vehicle headlights.

摘要

This invention relates to a shield to be used in a vehicle headlamp comprising a concave base member with curved or planar side wall sections having a channel member positioned in the central portion of the base member with the base of the channel projecting inwardly from the concave surface to prevent the direct light of the low beam filament from being projected or reflected forwardly as glare or uncontrolled light. The shield also acts to reduce and disperse the light it reflects thereby preventing excessive redirected light in unwanted regions.
