Abstract

L'invention concerne une lumière à deux côtés (10) et une lumière en guirlande. La lumière à deux côtés (10) comprend : un premier élément électroluminescent (100), un second élément électroluminescent (200) et un fil de connexion (300). Une région de montage (500) est disposée sur le fil de connexion (300). Le premier élément électroluminescent (100) et le second élément électroluminescent (200) sont tous deux disposés dans la région de montage (500). Le premier élément électroluminescent (100) et le second élément électroluminescent (200) sont tous deux connectés au fil de connexion (300). Une direction de diffusion de la lumière du premier élément électroluminescent (100) est opposée à une direction de diffusion de la lumière du second élément électroluminescent (200). Le premier élément électroluminescent (100) et le second élément électroluminescent (200) sont situés dans la région de montage (500) et sont tous deux connectés au fil de connexion (300) et le premier élément électroluminescent (100) et le second élément électroluminescent (200) sont conçus pour être dos à dos, de telle sorte que la lumière se diffuse de manière omnidirectionnelle et uniforme, ce qui permet de résoudre le problème technique en l'état de la technique selon lequel une surface arrière d'une puce de DEL émet faiblement la lumière et la lumière n'est pas diffusée de manière omnidirectionnelle. L'invention permet d'obtenir une lumière à DEL en fil de cuivre qui diffuse de la lumière de manière omnidirectionnelle sans apparition de régions sombres.
