Zusammenfassung:	Embodiments of invention are directed to a lighting device for use in accent lighting applications. In one embodiment, the lighting device includes a coherent light source, such as a laser, and a diffractive optical element. The diffractive optical element may be, for example, a holographic optical element. The lighting device may be adapted to retrofit into a pre-existing light fixture. In one application, the lighting device may project a static or movable star field and/or static or movable clouds. L'invention concerne un dispositif d'éclairage pouvant être utilisé dans des applications d'éclairage d'ornement. Dans un mode de réalisation, le dispositif d'éclairage comprend une source de lumière cohérente, telle qu'un laser, et un élément optique diffractif. L'élément optique diffractif peut être, par exemple, un élément optique holographique. Le dispositif d'éclairage peut être adapté pour être installé dans un appareil d'éclairage préexistant. Dans une application, le dispositif d'éclairage peut projeter un champ d'étoiles statiques ou en mouvement et/ou des nuages statiques ou en mouvement.
