PROJECTION DEVICE, REAR-VIEW DEVICE AND MOTOR VEHICLE

The invention relates to a projection device (36) for projecting visual information, in particular in the form of a logo or warning signal, and to a projection surface (48), having a light source (38)which has an emission maximum at a first wavelength, a mask (40) which is arranged in the beam path of the light source (38) and has at least one opening which makes available the visual information,and at least one optical lens (46, 50) arranged in the beam path, wherein the mask (40) and/or the lens (46, 50) have/has a coating (44) with at least one fluorescent material, the excitation wave length of which corresponds to the first wavelength, and which emits light at least one second wavelength. The invention also relates to a rear-view device and to a motor vehicle having such a projection device (36). 本发明涉及一种用于将光学信息投影到投影面(48)上的投影装置(36)，所述光学信息特别是以图标或者警告信号的形式，所述投影装置具有：光源(38)，所述光源在第一波长处具有最大发射；设置在光源(38)的光路中的蔽光框(40)，所述蔽光框具有至少一个提供光学信息的开口；以及至少一个设置在光路中的光学透镜(46、50)，其中，所述蔽光框(40)和/或所述透镜(46、50)具有包括至少一种发光材料的涂层(44)，所述发光材料的
