Abstract: An induction heating device includes a case, a cover plate, a working coil, a base plate, a light guide that is located around the working coil and includes a light-emitting surface that indicates an output intensity of the working coil or an operation state of the working coil, and a light-emitting element that emits light toward the light guide. The light guide includes a light-guiding portion that has a lower surface having a parabolic shape and an upper surface including the light-emitting surface in which the upper surface extends in a first direction farther than the lower surface, and a light-guiding support that couples to the base plate, that surrounds at least a portion of the light-guiding portion, and that reflects, toward the light-guiding portion, at least one of light that has been emitted from the light-emitting element or light that has been guided through the light-guiding portion.

Abstract: A light transmissive injection molded article is disclosed. In the light transmissive injection molded article of the present invention, one or more planes are formed at a front surface and a back surface. The planes of the back surface form a light reflection pattern configured to reflect light passing through the front surface toward the front surface. The planes of the back surface include a first inclined surface, a second inclined surface, and a third inclined surface. The first inclined surface is a plane inclined with respect to a normal direction of the front surface. The second inclined surface is a plane gradually approximating to the front surface as the second inclined surface extends far from the first inclined surface. The third inclined surface is a plane gradually approximating to the front surface as the third inclined surface extends far from the second inclined surface.
