Japanese Patent JP4768179
Kind Code:
B2
Abstract:
A headlamp (2; 3) of a vehicle (1) has a light source (4; 5) comprising a plurality of opto-electronic elements (11; 12; 13; 14), preferably light-emitting diodes (LED's). At least one of these opto-electronic elements (11; 12; 13; 14) has, in operation, a luminous flux of 5 lm or higher. According to the invention, the spectral characteristic of the light beam (6, 6'; 7, 7') generated by the light source (4; 5) depends upon the position in the light beam (6, 6'; 7, 7'). Preferably, the light source (4; 5) comprises opto-electronic elements (11; 12; 13; 14) only. The light beam comprises at least two light beam segments (6, 6'; 7, 7') having essentially different spectral characteristics. Preferably, one of the light beam segments (6'; 7') is mesotopically tuned. In particular, a first light beam segment (6; 7) comprises a considerable amount of white or yellow-orange light, and a second light beam segment (6'; 7') comprises a considerable amount of blue-green light.
