  • Patent number: 11735358
    Abstract: A bonded magnet is provided which includes first and second components. The first and second components have first and second non-action surfaces, and first and second action surfaces that intersect the first and second non-action surfaces, respectively. First and second flux groups curve inside the first and second components from the first and second non-action surfaces to the first and second action surfaces, respectively. The areas of the first and second non-action surfaces are greater than the first and second action surfaces, respectively. The flux densities on the first and second action surfaces are higher than the first and second non-action surfaces, respectively. The pole on the first non-action surface is opposite to the second non-action surface. The first and second non-action surfaces are coupled to each other. The first flux groups continuously extend from one to another.

  • Patent number: 7446828
    Abstract: A light emitting apparatus that is capable of emitting light with uniform intensity and high luminance are provided. The first optical guide comprises a first principal surface that has an effective light emitting region of substantially rectangular shape surrounded by first through fourth sides and a second principal surface that opposes the first principal surface, wherein the circumferential side face of the optical guide includes first through fourth side faces disposed along the first through fourth sides, respectively, and a light introducing section, disposed at the corner interposed between the first and second side faces, with an angle of inclination from the first side face that is determined so that center axis of light distribution intersects one of the first through fourth sides and divides the area of the effective light emitting region into two equal parts.
