摘要： A lighting reflector 10 includes a base member 11, made of metal, having an inner circumferential surface 13a expanding toward a light exit aperture 14 open at an end in an axial direction. A thin-film layer 17 which is formed from a thin film containing ceramic and which scatters light is placed on an end portion of the inner circumferential surface 13a that is on the opposite side to the light exit aperture 14.

摘要： Image capturing accuracy is improved while a simple optical system is used. An image capture device includes: a polarizing filter that blocks non-transmitted light that has been in polarized light of an infrared ray radiated from a light source and has not been transmitted through an image capturing target and transmitted light that has been in the polarized light and has been transmitted through the image capturing target without diffusion inside the image capturing target, and transmits transmitted light that has been in the polarized light and has been diffused inside the image capturing target and transmitted therethrough; and an image sensor that receives the light that has been transmitted through the polarizing filter and captures an image of the image capturing target.

摘要： Light emission efficiency is increased in an eye-safe light source by regulating light distribution properties. An eye-safe light source includes a package, a semiconductor laser that emits laser light from a left light emission end surface and a right light emission end surface, and a wire that is joined to the semiconductor laser. The semiconductor laser is joined to the package such that the laser light is emitted parallel to an upper surface of a lead frame of the package. The package includes reflection surfaces that face the left light emission end surface and the right light emission end surface and reflect the laser light. In top view, a direction in which the wire extends is perpendicular to a direction of emission of the laser light.

摘要： An LED chip (3) is disposed in a recessed portion (21p) formed by bending a metal lead frame (2). A reflector (4) has a resin reflection surface (4a) and the recessed portion (21p) has a metal reflection surface (21a). When the inclination angle of at least one metal reflection surface (21a) is θs2(°), the resin reflection surface (4a) has a sloped resin surface with an inclination angle of θs1(°) that is smaller than θs2(°). With θc(°) defined as the critical angle of light emitted from an LED chip (3) and incident on the interface between a light-transmissive resin (5) and an air layer, the sloped resin surface and metal reflection surface having a relationship of θs1

A glass-based insulator layer (13) is formed at least on the other side of the base (14) that is opposite the one side of the base (14). Therefore, a light-emitting device substrate having high reflectivity, high heat dissipation capability, dielectric withstand capability, and long-term reliability and excellent in mass productivity can be realized.
