Patent ID: 8010259

Claim:
An irradiating direction control apparatus for a vehicle lamp capable of controlling deflection of an irradiating direction, the apparatus comprising: a vehicle height detector for detecting a vehicle height of a vehicle; a controller for controlling deflection of the lamp based on the vehicle height detected by the vehicle height detector; and a storing portion including an output electric value storing region and a design reference value storing region, wherein the controller is adapted to store a design reference value of the vehicle in the design reference value storing region and to store a detected electric value output by the vehicle height detector when the vehicle is in a reference position in the output electric value storing region as a measured reference value, the controller being further adapted to determine a reference vehicle height based on the measured reference value and the design reference value and to determine a pitch angle of the vehicle based on the detected output of the vehicle height detector and the reference vehicle height, and to control deflection of the irradiating direction of the lamp based on the pitch angle.
