Japanese Patent JP2003503253
Kind Code:
A
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 (LEDs). 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 spatial distribution of the light beam (6, 6', . . . ; 7, 7', . . . ) generated by the light source (4; 5) is continuously adjustable. Preferably, the light source (4; 5) comprises opto-electronic elements (11; 12; 13; 14) only. Preferably, the spatial distribution is influenced by the speed of the vehicle (1), the rotational position of the steering wheel of the vehicle (1), the weather conditions, and it can also be influenced by the driver of the vehicle (1). Preferably, the spectral characteristics of the light beam (6, 6', . . . ; 7, 7', . . . ) generated by the light source (4; 5) depend on the position in the light beam (6, 6', . . . ; 7, 7', . . . ). The light beam comprises at least two light beam segments (6, 6'; 7, 7') having essentially different spectral characteristics.
