Abstract: A light-emitting element array includes a substrate, plural light-emitting elements arranged on the substrate, plural constriction grooves being provided in a periphery of each of the plural light-emitting elements, and forming a current constriction layer that constricts a current flowing through a light-emitting layer by oxidizing the light-emitting layer, and a block separation portion that is formed so as to overlap a part of the plural constriction grooves in plan view, and separates the plural light-emitting elements into plural blocks.

Abstract: A light-emitting device includes: a first light source that oscillates in a single lateral mode; a second light source that oscillates in a multiple lateral mode, the second light source having a light output larger than a light output of the first light source and being configured to be driven independently from the first light source; and a light diffusion member that is provided on an emission path of the second light source.

Abstract: 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.
