Abstract:
Disclosed herein is a drive unit using a shape memory alloy including: a shape memory alloy member made from a shape memory alloy, the shape memory alloy member exhibiting superelasticity when being energized; a drive body connected to the shape memory alloy member, the drive body being moved from a stopping position to a specific operational position when the shape memory alloy member is energized; and a locking mechanism for retaining the drive body at the specific operational position. With this configuration, the drive unit using a shape memory alloy is capable of reducing the power consumption as well as miniaturizing the drive unit.

PROBLEM TO BE SOLVED: To obtain a thin illuminator in which the height (thickness) of the emission opening part can be made lower (thinner) so that the illuminator can be directly mounted to a circuit board. SOLUTION: In an illuminator 110A, a reflector 330A is arranged above the arc tube 340 relative to the direction of radiation axis. The cross-sectional shape of the main reflection plane 331a of a main reflector 331A is formed into an approximately elliptic curve or an approximately parabolic curve both having an arc tube 330A as the focus. Opposite to the main reflector 331A, a subreflector 332A provided with a semicircular reflection plane 332a having the focus of the arc tube 340 as the center is arranged.
