Title
(EN) WAVELENGTH CONVERSION DEVICE AND RELATED LIGHT-EMITTING DEVICE THEREOF

Abstract
(EN) Provided is a wavelength conversion device (100), comprising a substrate (130), a reflecting layer (120), and a light-emitting layer (110) superimposed successively. The light-emitting layer (110) contains a wavelength conversion material and a second binder, and the reflecting layer (120) contains reflecting particles, auxiliary particles, and a first binder. The reflecting particles are used for reflecting light, and the auxiliary particles are used for filling voids between the reflecting particles. The first binder is used for binding the reflecting particles and auxiliary particles into a layer. The reflecting layer (120) not only ensures a higher reflectivity, but also achieves a lower thickness, such that the heat produced by the light-emitting layer (110) can be better transmitted to the substrate through the reflecting layer (120), which avoids a decrease in the light conversion efficiency caused by an excessively high temperature of the light-emitting layer (110). Also disclosed is a light-emitting device comprising such a wavelength conversion device (100).
(FR) L'invention concerne un dispositif de conversion de longueur d'onde (100), comprenant un substrat (130), une couche réfléchissante (120), et une couche électroluminescente (110) superposés successivement. La couche électroluminescente (110) contient un matériau de conversion de longueur d'onde et un second liant, et la couche réfléchissante (120) contient des particules réfléchissantes, des particules auxiliaires, et un premier liant. Les particules réfléchissantes sont utilisées pour réfléchir la lumière, et les particules auxiliaires sont utilisées pour remplir les vides entre les particules réfléchissantes. Le premier liant est utilisé pour lier les particules réfléchissantes et les particules auxiliaires en une couche. La couche réfléchissante (120) assure non seulement une réflectivité supérieure, mais permet également d'obtenir une épaisseur inférieure, de telle sorte que la chaleur produite par la couche électroluminescente (110) peut être mieux transmise au substrat au moyen de la couche réfléchissante (120), ce qui permet d'éviter une diminution de l'efficacité de conversion de lumière causée par une température trop élevée de la couche électroluminescente (110). En outre, l'invention concerne également un dispositif électroluminescent comprenant un tel dispositif de conversion de longueur d'onde (100).
(ZH) 一种波长转换装置(100),包括依次叠置的基板(130)、反射层(120)和发光层(110)。发光层(110)包含波长转换材料和第二粘结剂,反射层(120)包含反射粒子、辅助粒子和第一粘结剂。反射粒子用于对光进行反射,辅助粒子用于填充反射粒子间的缝隙。第一粘结剂用于将反射粒子和辅助粒子粘结成层。反射层(120)既保证了较高的反射率,又实现了较低的厚度,从而使得发光层(110)产生的热量更好的通过反射层(120)传递到基板,避免了发光层(110)温度过高而造成的光转换效率下降。此外,还公开了一种包含这种波长转换装置(100)的发光装置。
