  "textContent": "A swivel angle setting unit (90) is configured to perform a first mode in which a swivel angle of a lamp unit (10) is set such that a light distribution pattern follows the travelling direction of the vehicle based on the curvature estimated by a curvature estimation unit (78), and perform a second mode in which a swivel angle of the lamp unit (10) is set such that a shielded area created in a light distribution pattern follows the position of the vehicle detected by a vehicle position detector (76). A pattern determination unit (80) determines a light distribution pattern such that the position of the vehicle remains in the shielded area. A swivel angle setting unit (90) performs the first mode when determined that the road is a curved road based on the curvature, and performs the second mode when determined that the road is a straight road.",
