The reflector may include a body part having a circular column shape having a vacant space therein and having openings formed in upper and lower surfaces thereof, a first rotary body connected to a lower surface of the body part and shaped to have a vacant space therein, and a second rotary body connected to an upper surface of the body part and shaped to have a vacant space; a first LED light source may emit UV-C rays in a direction from the first rotary body to the body part; and a second LED light source may emit UV-C rays in a direction from the second rotary body to the body part, and the reflector may reflect the light emitted from the first LED light source and the light emitted from the second LED light source.

Abstract: A side view mirror is disclosed. The side view mirror comprises: a mirror; a mirror housing supporting the mirror; and an infrared object detecting module that is fixed to the outside of the mirror housing, emits infrared rays in a direction in which the mirror housing or the mirror is oriented, and uses reflected light from the emitted infrared rays to determine whether an object is present in the direction in which the mirror housing or the mirror is oriented.

Abstract: Provided is a stereoscopic display device, including: a base member transmitting an incident beam; and a three-dimensional effect forming part on a first surface of the base member, wherein the three-dimensional effect forming part has a pattern, the pattern having multiple pattern units arranged in a concentric circular, elliptical or polygonal radial form, each of the pattern units having an inclined surface having an inclination angle with respect to the first surface, and wherein when an incident beam is incident to a central portion of the pattern, the pattern guides the incident beam in a first surface direction toward which the first surface looks or a second surface direction toward which a second surface opposite to the first surface looks, thereby displaying a line-shaped beam having a three-dimensional effect in a first path resulting a pattern arrangement direction.
