    摘要: A lamp device is provided that is capable of performing a first actuation and a second actuation. At the first actuation, the lamp device pivots a lamp about a first axis relative to a support, and, at the second actuation, the lamp device pivots the lamp about a second axis, which is perpendicular to the first axis, relative to the support. The lamp includes a first supporting portion that is located on the first axis and at a side of the lamp and a second supporting portion that is located on the first axis and at the other side of the lamp. The first supporting portion is supported by the support to be pivotable about the intersection point of the first axis and the second axis. The second supporting portion is joined to a movable joint member. The movable joint member is supported by the support so as to be movable along a second actuation axis.
