摘要： An automotive lamp capsule (12) containing filament (24) mounted within a capsule envelope (20) that has a light-transmissive coating (60) that increases the color temperature of light passing therethrough. Two uncoated windows (62) on envelope (20) in register with filament (24) extend towards capsule base (20) and alternate, in a direction circumferentially around capsule envelope (20), with two coated portions (64) at that axial location along optical axis (O). A distance from filament (24) to a lower edge (68) of window (62) bounds a region of light emitted from filament (24) whose color temperature is not increased by coating (60) and defines the hot spot (105) in a beam projected from a vehicle reflector (14) in which capsule (12) is mounted. Light emitted by filament (24) passing adjacent to windows (62) through regions of coating (60) form a spread light pattern (112) of advantageous, higher color temperature than previously achievable.
