A light emitter includes: a substrate; a driving section provided on the substrate; a light source that is provided on the substrate and is driven by the driving section; a cover section through which light emitted from the light source is transmitted and that is disposed in an optical axial direction of the light source; and a support section that is provided on a part of the substrate excluding a part between the driving section and the light source and supports the cover section.

Light emitter, light emitting device, optical device, and information processing apparatus

A light-emitting component includes a substrate, plural light-emitting elements that are disposed on the substrate and emit light in a direction intersecting with a surface of the substrate, and a gate electrode that is electrically connected to each of the plural light-emitting elements and performs control so that the plural light-emitting elements are switched ON/OFF together. Plural holes are disposed around each of the plural light-emitting elements.

Light-emitting component, light-emitting element array chip, and optical measurement apparatus

A light emitting apparatus includes a substrate and light emitting elements including at least one light emitting element that is provided, on the substrate, in each region of plural regions and that emits irradiation light toward a target object, the regions including a first region and a second region and being isolated from each other to be arranged one-dimensionally or two-dimensionally. In the plural regions, an irradiation light amount of at least one light emitting element provided in the first region that is a region located at an end in an arrangement direction is larger than an irradiation light amount of at least one light emitting element provided in the second region that is a region located at a place other than the end in the arrangement direction.

Light emitting apparatus and information processing apparatus

A light-emitting device is provided with a light source and a controller. The light source includes multiple light-emitting elements and multiple driving elements that are provided in correspondence with the light-emitting elements and drive the light-emitting elements to light up by going to an ON state. The controller controls a switching between a successive lighting operation that causes the light-emitting elements to light up successively and a simultaneous lighting operation that causes the light-emitting elements to light up simultaneously in parallel. The light source includes a power supply line set to a reference potential or a power supply potential, a driving signal line that is connected to the power supply line and that supplies a driving signal to the driving elements, and a lighting signal line that supplies a lighting signal for causing the light-emitting elements to light up. In the successive lighting operation, the controller sets the power supply line to the power supply potential and sets each driving element to the ON state with the driving signal and the lighting signal to cause each light-emitting element corresponding to each driving element to light up successively. In the simultaneous lighting operation, the controller sets the power supply line to the reference potential and also sets the driving elements to the ON state with the driving signal and the lighting signal to cause the light-emitting elements to light up simultaneously in parallel.

Light-emitting device, optical device, measuring device, and information processing device

A light emitting element formed of a laminate having a current constriction layer includes: a semiconductor substrate; a light emitting portion having plural first recess portions having a depth reaching the current constriction layer, and a current constriction structure formed in the current constriction layer and having an oxidized region where the current constriction layer is oxidized and a non-oxidized region surrounded by the oxidized region; an electrode pad disposed between the light emitting portion and an outer edge portion of the semiconductor substrate; and a step portion disposed between the electrode pad and the light emitting portion and formed from an upper surface of the laminate to the current constriction layer, and the current constriction layer in a region surrounded by the step portion is the oxidized region except for the non-oxidized region.

Light emitting element

A light-emitting device includes a light diffusing member that diffuses light emitted from a light source so that an object to be measured is irradiated with the light; and a holding unit that holds the light diffusing member and is provided on a wire connected to the light source so as to be located in an uncoated region of the wire.
