Abstract
(EN)
The present invention relates to a light-emitting device and a vehicular lamp comprising same. The light-emitting device according to one embodiment of the present invention comprises: a light-emitting unit comprising a light-emitting element; and a sidewall unit surrounding the sides of the light-emitting unit and coming into contact with the sides of the light-emitting unit, wherein the light-emitting element comprises two or more light-emitting cells grown on one growth substrate and the two or more light-emitting cells may be electrically connected to one another. The present invention has the effect of minimizing the shadow generated between the light-emitting cells by using one light-emitting diode chip comprising the two or more light-emitting cells while providing an amount of light the same as or more than when using two or more light-emitting diode chips.

La présente invention concerne un dispositif électroluminescent et une lampe de véhicule comprenant celui-ci. Le dispositif électroluminescent, selon un mode de réalisation de la présente invention, comprend : une unité électroluminescente comprenant un élément électroluminescent ; et une unité de paroi latérale entourant les côtés de l'unité électroluminescente et venant en contact avec les côtés de l'unité électroluminescente, l'élément électroluminescent comprenant deux ou plus de deux cellules électroluminescentes croissant sur un substrat de croissance et les deux ou plus de deux cellules électroluminescentes pouvant être électriquement connectées l'une à l'autre. La présente invention a pour effet de réduire au minimum l'ombre générée entre les cellules électroluminescentes au moyen d'une puce de diode électroluminescente comprenant les deux ou plus de deux cellules électroluminescentes tout en fournissant une quantité de lumière égale ou supérieure à celle fournie lors de l'utilisation de deux ou plus de deux puces de diode électroluminescente.
