Title (EN) COLOR WHEEL DEVICE AND PROJECTION APPARATUS
(FR) DISPOSITIF DE CERCLE CHROMATIQUE ET APPAREIL DE PROJECTION
(ZH) 色轮装置及投影设备
Abstract:
(EN) A color wheel device, comprising: a low heat conducting substrate (10); a heat dissipating assembly (30), fixed on the low heat conducting substrate (10) and configured to surround the circle center of the low heat conducting substrate (10); and a wavelength conversion layer (40), provided on the heat dissipating assembly (30). The color wheel device improves heat dissipating efficiency, and reduces the heat transferred by the wavelength conversion layer (40) to other members connected to the low heat conducting substrate (10), improving the operation efficiency of other members. Further provided is a projection apparatus comprising the color wheel device.
(FR) L'invention concerne un dispositif de cercle chromatique, comprenant : un substrat faiblement conducteur de chaleur (10); un ensemble de dissipation de chaleur (30), fixé sur le substrat faiblement conducteur de chaleur (10) et conçu pour entourer le centre du cercle du substrat faiblement conducteur de chaleur (10); et une couche de conversion de longueur d'onde (40), disposée sur l'ensemble de dissipation de chaleur (30). Le dispositif de cercle chromatique améliore le rendement de dissipation de chaleur et réduit la chaleur transférée par la couche de conversion de longueur d'onde (40) vers d'autres éléments connectés au substrat faiblement conducteur de chaleur (10), ce qui améliore le rendement de fonctionnement d'autres éléments. L'invention concerne en outre un appareil de projection comprenant le cercle chromatique.
(ZH) 一种色轮装置,包括低导热基板(10);散热组件(30),固定在低导热基板(10)上,且环绕低导热基板(10)的圆心设置;波长转换层(40),设置于散热组件(30)上。该色轮装置提高了散热效率,减少了波长转换层(40)传递至与低导热基板(10)连接的其它部件的热量,提高其它部件的工作效率。同时,还提供包括该色轮装置的投影设备。
