<P>PROBLEM TO BE SOLVED: To improve a transmission rate of information relating to the control of a plurality of semiconductor light sources, when controlling a head lamp achieved by using a plurality of semiconductor light sources. <P>SOLUTION: A control device 100 controls a vehicle head lamp when the vehicle head lamp that can partially change brightness in the irradiation area according to the operation mode is achieved by using a plurality of LED (light emitting diodes). The control device 100 includes: a mode information receiving part that receives the mode information that specifies the part of the irradiation area which shows the on/off of the operation mode and has to change the brightness when the operation mode is on through a first communication line LIN; a state decision part that decides the state of each LED based on the part of the irradiation area that the mode information specifies, when the received mode information shows on of the operation mode; and a light source control part where each LED is controlled to become a state decided by the state decision part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
