Abstract: An LED lighting device 10 includes: a substrate 15 formed in an elongated shape; a first reflector 11 formed in a single rail shape on the surface of the substrate 15; plural LED elements 16 (16a and 16b) arranged in rows at positions on both sides of the first reflector 11 on the surface of the substrate 15; and a pair of rail-shaped second reflectors 12 (12a and 12b) formed on the surface of the substrate 15 in such a manner that the LED elements 16 (16a and 16b) and the first reflector 11 are interposed between the pair of second reflectors 12a and 12b.

Abstract: A reflector used in an electronic flash device that collectively emits direct light emitted from a light source and reflected light that has been reflected by a reflective surface onto a subject, and an electronic flash device that uses such reflector. The reflector includes a pair of first reflective surfaces that are composed of portions of a cylindrical curved surface and face one another, and a second reflective surface that is contiguous with the pair of first reflective surfaces and inside which a xenon lamp is housed. Contiguous portions where the pair of first reflective surfaces and the second reflective surface are contiguous are set closer to the opening of the pair of first reflective surfaces than a center of the xenon lamp. With this construction, by it is possible to maintain a predetermined optical performance while making the electronic flash device smaller and slimmer.

Abstract: A reflector used in an electronic flash device that collectively emits direct light emitted from a light source and reflected light that has been reflected by a reflective surface onto a subject, and an electronic flash device that uses such reflector. The reflector for an electronic flash device includes a pair of first reflective surfaces 24, 25 that are composed of portions of a cylindrical curved surface and face one another and a second reflective surface 26 that is contiguous with the pair of first reflective surfaces 24, 25 and inside which a xenon lamp 12 is housed. Contiguous portions B1, B2 where the pair of first reflective surfaces 24, 25 and the second reflective surface 26 are contiguous are set closer to the opening 13a of the pair of first reflective surfaces 24, 25 than a center O of the xenon lamp 12 that is the light source.
