Abstract
La présente invention concerne une lampe à DEL dans laquelle une feuille optique électroluminescente formée en traitant un motif de plaque guide de lumière sur une feuille à prisme est positionnée à l'intérieur d'un diffuseur cylindrique pour garantir un angle d'émission de 360 degrés. La lampe à DEL selon la présente invention comprend : un diffuseur cylindrique pour diffuser de la lumière ; une feuille optique électroluminescente, qui est positionnée à l'intérieur du diffuseur cylindrique pour garantir un angle d'émission de 360 degrés, et qui est traitée en un motif de points sur la surface arrière de la plaque guide de lumière ; et un ou plusieurs modules DEL qui reçoivent de l'énergie à partir d'une source externe par l'intermédiaire de bornes de connexion afin d'émettre de la lumière dans le diffuseur cylindrique.
