An aspect of the present invention relates to a lighting device (1) for an ambient lighting system (100) of a vehicle (200), comprising: at least one lighting element (10, 20, 30) having a first side (11, 21, 31) and an opposite second side (12, 22, 32) facing a viewer (V) of the lighting device (1), the at least one lighting element (10, 20, 30) comprising: a LED light source (13, 23, 33) configured to emit excitation light (EX1, EX2, EX3) of an excitation wavelength range; a phosphorescent material (14, 24, 34) configured to emit visible emission light (EM1, EM2, EM3) of an emission wavelength range in response to being illuminated with the excitation light (EX1, EX2, EX3) emitted by the LED light source (13, 23, 33), the phosphorescent material (14, 24, 34) being arranged between the first and the second side (11, 21, 31; 12, 22, 32) of the at least one lighting element (10, 20, 30); and at least one notch filter (15, 25, 35) arranged at the second side (12, 22, 32) of the at least one lighting element (10, 20, 30) and configured to filter light in or of the excitation wavelength range of the excitation light (EX1, EX2, EX3) out of light emitted by a light source (40) external to the at least one lighting element (10, 20, 30) and incident in direction of the second side (12, 22, 32) of the at least one lighting element (10, 20, 30) on the phosphorescent material (14, 24, 34). Further aspects relate to a vehicle lighting system and a vehicle comprising said vehicle lighting system.
