Abstract
Hinge devices couple light source units to a base such that the light source units are rotatable around first axes. Each light source unit is rotatable between a first position and a second position around a corresponding first axis of the first axes. Rotation mechanisms couple the light source units to the hinge devices such that the light source units are rotatable around second axes transverse to the first axes. The hinge devices are configured such that when each light source unit rotates from the first position to the second position, rotation directions of the light source units are different. The rotation mechanisms define rotation ranges of the light source units around the second axes to achieve a reference state where the light source units are collected together and light-outgoing surfaces of the light source units face outward when each light source unit is in the first position.
