(FR) DISPOSITIF ÉLECTROLUMINESCENT ET PROJECTEUR
(JA) 発光装置およびプロジェクター
Abstract:
(EN) Provided is a light-emitting device that makes it possible to improve light emission efficiency. The light-emitting device includes a substrate, a light source, and a plurality of columnar sections provided to the substrate, said columnar sections comprising a first fluorescent material that uses the light emitted from the light source to emit light. The light source irradiates the columnar sections with light obliquely.
(FR) L'invention concerne un dispositif électroluminescent permettant d'améliorer l'efficacité d'émission de lumière. Le dispositif électroluminescent comprend un substrat, une source de lumière et une pluralité de sections en colonne disposées sur le substrat, lesdites sections en colonne comprenant un premier matériau fluorescent qui utilise la lumière émise par la source de lumière pour émettre de la lumière. La source de lumière applique obliquement de la lumière sur les sections en colonne.
(JA) 発光効率を向上させることができる発光装置を提供する。 基体と、光源と、前記基体に設けられ、前記光源から射出された光により、光を発する第1蛍光体を有する複数の柱状部と、を含み、前記光源は、前記柱状部に対し斜めに光を照射する、発光装置。
