A light emitting device comprises a substrate a plurality of light emitting elements provided on the substrate, and a reflective sheet provided to be positioned at a predetermined reference position on the substrate and having a plurality of apertures that expose the light emitting elements therethrough, respectively. The apertures are configured such that a first spacing that is located between each of the apertures and a respective one of the light emitting elements and farther than the respective one of the light emitting elements from the reference position is larger than a second spacing that is located between each of the apertures and the respective one of the light emitting elements and closer than the respective one of the light emitting elements to the reference position.

Light emitting device with reflective sheet having apertures

A light emitting device comprises a light emitting substrate with a plurality of light emitting elements, a luminance equalizer sheet provided opposite the light emitting substrate and having a plurality of through holes for transmitting light irradiated from the light emitting elements; and a holding member having a first holding surface that supports the light emitting substrate and has a first engagement portion that is engaged with the first emitting substrate, and a second holding surface that supports at least an edge portion of the luminance equalizer sheet and has a second engagement portion that is engaged with the edge portion of the luminance equalizer sheet, the first engagement portion and the second engagement portion being aligned with respect to each other on a predetermined plane, and a distance between the first holding surface and the second holding surface increasing or decreasing as moving away from the predetermined plane.

Light emitting device and display device

A light emitting device comprises a light emitting substrate with a plurality of light emitting elements, and a luminance equalizer sheet provided opposite the light emitting substrate, having a plurality of through holes for transmitting light irradiated from the light emitting elements and having a linear expansion coefficient different from a linear expansion coefficient of the light emitting substrate, the light emitting substrate and the luminance equalizer sheet being positioned relative to each other at a predetermined position, at least one with a larger linear expansion coefficient among the light emitting substrate and the luminance equalizer sheet having a curved shape, and a degree of curvature of the one with the larger linear expansion coefficient being larger than a degree of curvature of one with a smaller linear expansion coefficient among the light emitting substrate and the luminance equalizer sheet.

An image capturing device includes an image capturing unit, a fitting member, and a cover member. The image capturing unit captures a plurality of unit images having parallax by using a lens array having a plurality of unit lenses, and a prism. The fitting member is provided with a mounting portion upon which said prism is mounted. The cover member is put onto the fitting member from its side which faces the mounting portion. The mounting portion has a shape which, in the state in which the prism is mounted, grips two contiguous faces of the prism. And the cover member has a pair of claws which, when the cover member is put onto the fitting member, squeeze two contiguous faces of the prism which is mounted to the mounting portion.

Image capturing device

A center lens for collecting light in a center range and left/right lenses for collecting light in left/right ranges are supported in one plane to form center and left/right unit images. A microprocessor combines the unit images into a wide-angle image. The left/right optical lenses are placed on left-right direction line parallel to the wide-angle direction, while the center lens is placed distant from the left/right lenses above the direction line. Prisms are placed in front of the left/right lenses, and a toroidal lens to vertically modify the light path for light convergence onto each lens is placed in front of the prisms. The toroidal lens has a vertically curved surface having an axis coinciding with the direction line, and a horizontally cured surface having an axis coinciding with a vertical line passing through the center lens. This device can obtain a wide-angle image with a vertically large picture angle.

Wide-angle compound-eye imaging device

This image capturing device includes a fitting member, a lens attached by adhesive to the fitting member, and a light reception element. The light reception element is disposed so as to face the lens attached to the fitting member, and an image of a photographic subject is projected upon this light reception element by the lens. An image output unit is also provided which outputs this image of the photographic subject projected upon the light reception element by the lens. And an application aperture for adhesive is provided in the fitting member at a position facing a region of the lens which does not contribute to the image of the photographic subject outputted by the image output unit. Desirably, a plurality of such admission apertures are provided.

An image pickup apparatus includes a first lens for converging light incident thereto through a first field area, a first prism to which light is incident through a second field area at a right of the first field area, a second lens for converging the light emitted from the first prism, a second prism to which light is incident through a third field area at a left of the first field area, and a third lens for converging the light emitted from the second prism. The respective lenses are placed at areas corresponding to the vertices of a triangle in a front view.
