Abstract
(EN)
A light-emitting element array provided with a light-emitting element group including a plurality of light-emitting elements, and a plurality of lenses which are provided on the output surface side of the plurality of light-emitting elements and in correspondence to the plurality of light-emitting elements, and which deflect light from the plurality of light-emitting elements on the basis of a positional relationship with the plurality of light-emitting elements. From the center of the light-emitting element group toward the end side thereof, the distance between the light-emitting central axis of the plurality of light-emitting elements and the central axis of the plurality of lenses corresponding to the plurality of light-emitting elements becomes greater and the degree of change in distance becomes smaller.

L'invention concerne un réseau d'éléments électroluminescents comprenant un groupe d'éléments électroluminescents comprenant une pluralité d'éléments électroluminescents, et une pluralité de lentilles qui sont disposées sur le côté de surface de sortie de la pluralité d'éléments électroluminescents et en correspondance avec la pluralité d'éléments électroluminescents, et qui dévient la lumière provenant de la pluralité d'éléments électroluminescents sur la base d'une relation de position avec la pluralité d'éléments électroluminescents. Depuis le centre du groupe d'éléments électroluminescents vers le côté d'extrémité de celui-ci, la distance entre l'axe central d'électroluminescence de la pluralité d'éléments électroluminescents et l'axe central de la pluralité de lentilles correspondant à la pluralité d'éléments électroluminescents devient supérieure et le degré de changement de distance devient plus petit.
