A frame member is attached to an opening in an outer light-reflection plate. The frame member is composed of an inner frame part, and an outer frame part disposed around the inner frame part. A light extraction part is formed between the outer frame part and the inner frame part. The inner frame part is constituted by a separate extraction part that extracts acoustic vibrations and light. A space of the separate extraction part includes, on both ends, a sound intake port on an internal space side where a sound source is disposed, and a sound extraction port formed in the top of the inner frame part so as to open toward the outside of an LED illumination device. The sound intake port and the sound extraction port are formed separated from each other by a prescribed distance, and the space is formed continuously in the inner frame part so as to connect the sound intake port and the sound extraction port.

A frame has an outer frame made of microcellular foam resin, and two inner frames made of the microcellular foam resin. The two inner frames are arranged together inside the outer frame. Both of the inner frames and the outer frame include openings provided at respective upper portions and recess portions formed downwardly from the openings, respectively. An LED light source, which is arranged inside a light guide space, emits light with a light emitting face thereof directing toward the light guide space. Accordingly, light from the LED light source is uniformly emitted from a light extraction portion. Also, an LED light source arranged inside a light guide space emits light directing toward the light guide space. Accordingly, light from the LED light source is uniformly emitted from a light extraction portion.

A shielded cable is mainly configured by an electromagnetic shielding tube, a terminal, and an electric wire or the like. An electric wire is inserted into an inside of the electromagnetic shielding tube. The terminal is connected to both end portions of the electric wire that serves as a covered wire. In the present invention, a structure in which the terminal is connected to the electric wire is called a structure of a shielded cable. The electromagnetic shielding tube is configured by an inner layer made of plastic, a metal layer made of metal, and an outer layer made of plastic. The electromagnetic shielding tube is configured such that the inner layer is formed on an innermost layer, the outer layer is formed on an outermost layer, and the metal layer is formed between the inner layer and the outer layer.
