Abstract: 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.

Abstract: An optical fiber including a glass core, and a polymer cladding formed around the glass core, the polymer cladding containing a mixture of a polymerizable composition and a silane coupling agent, and a fluorine-based ultraviolet curable resin. The mixture contains 5 to 95 parts by weight of the silane coupling agent based on 100 parts by weight of the total weight of the mixture. The fluorine-based ultraviolet curable resin alone has a refractive index in a range of 1.350 to 1.420 after ultraviolet curing. A component originated from the silane coupling agent is concentrated within a range of 20 μm or less in the polymer cladding from an interface between the glass core and the polymer cladding.

Abstract: A method of producing an optical fiber preform includes a silica glass body forming step of forming a silica glass body to be at least a portion of a core portion. The method includes an alkali-metal-doped silica glass body forming step of forming an alkali-metal-doped silica glass body doped with an alkali metal around the silica glass body such that the alkali-metal-doped silica glass body contacts the silica glass body. The method further includes a diffusing step of diffusing the alkali metal from the alkali-metal-doped silica glass body to the silica glass body by a heat treatment.
