Abstract: 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.

Abstract: A light-emitting component includes a substrate and plural light-emitting elements that are disposed on the substrate and emit light in a direction intersecting with a surface of the substrate and that are switched ON/OFF together. The plural light-emitting elements include a gate layer, the gate layer performing control so that the plural light-emitting elements are switched ON/OFF together, a film thickness of the gate layer being greater than a wavelength of light emitted from the plural light-emitting elements.

Abstract: A surface emitting laser element array includes multiple two-dimensionally arranged surface-emitting laser element groups each including multiple surface-emitting laser elements. The multiple surface-emitting laser element groups are drivable independently of each other. The multiple surface-emitting laser element groups are arranged in an arrangement region such that the number of surface-emitting laser element groups arranged in a first direction is larger than the number of surface-emitting laser element groups arranged in a second direction perpendicular to the first direction. An irradiation region irradiated with light emitted from the multiple surface-emitting laser element groups has a shape elongated in the first direction. The arrangement region in which the multiple surface-emitting laser element groups are arranged has an aspect ratio closer to 1:1 than the irradiation region.

Abstract: A light-emitting element array includes multiple light-emission instruction units arranged in a first direction; a first light-emitting element group row including light-emitting element groups each including a multiple light-emitting elements such that the light-emitting element groups are arranged in a direction intersecting the first direction; a second light-emitting element group row including light-emitting element groups each including a multiple light-emitting elements such that the second light-emitting element group row is arranged along the first light-emitting element group row in the first direction; and a multiple wiring lines that connect the multiple light-emission instruction units to the light-emitting element groups in the first light-emitting element group row and the light-emitting element groups in the second light-emitting element group row to provide a light-emission instruction. The multiple wiring lines are connected such that in response to the multiple light-emission instruction units sequentially providing a light-emission instruction in the first direction, the light-emitting element groups in the first light-emitting element group row sequentially emit light in the direction intersecting the first direction and, after turning on of the first light-emitting element group row is completed, the light-emitting element groups in the second light-emitting element group row sequentially emit light in the direction intersecting the first direction.
