A device and method for protecting personal property. The jointing holder enables the optical module to reduce the number of components, to be miniaturized, and to reduce the dimensional deviation at the time of the assembly, enabling high-precision assembly. In the protruding portion, a spherical concave portion adapted to engage with a spherical protruding portion of the rocking support member is formed as a depression. The annealing step involves forming first gettering sites in both sides of the wafer by annealing the wafer. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions.
