An illumination device, in particular an illumination device for a motor vehicle, comprises a light source for generating light which has components in a blue, green, and red wavelength range, and a holographic optic which the light emitted by the light source strikes, wherein the light striking the holographic optics is used at least partially for reconstructing a hologram, wherein the light emerges from the illumination device after interaction with the holographic optic, and wherein the light source is designed so that the spectral distribution (1) of the light emitted by the light source is adapted to the spectral diffraction efficiency (2) of the holographic optics. 本发明涉及一种照明装置、尤其是用于机动车辆的照明装置，其包括用于产生光的光源，所述光包括在蓝色、绿色和红色波长范围内的成分；以及全息光学器件，从所述光源发出的光照射到该全息光学器件上，其中，所述照射到全息光学器件上的光至少部分地用于全息图的重建，其中，所述光在与全息光学器件相互作用之后从照明装置中射出，并且光源这样构成，使得从光源发出的光的光谱分布(1)匹配于全息光学器件的光谱衍射效率(2)。
