Disclosed is a lighting device which has a simple configuration and which can be used to project desired shapes, letters, or the like onto physical objects, and which can easily change said shapes, letters or the like. The device is equipped with: an LED light source (3); a first refractive element (4) which refracts the light from the LED light source (3) and focuses it, in a predetermined position, into an image of an optically emitted shape as seen from the direction of the optical axis of the LED light source; and a casing (2) which houses the LED light source (3) and the first refractive element (4), and which has a light emission opening (2A) which emits light leaving the first refractive element (4) to the outside. L'invention concerne un dispositif d'éclairage présentant une configuration simple, qui peut être utilisé pour projeter des formes voulues, des lettres ou analogues, sur des objets physiques, et qui peut modifier facilement lesdites formes, lettres ou analogues. Le dispositif est équipé d'une source lumineuse LED (3); d'un premier élément de réfraction (4) qui réfracte la lumière provenant de la source lumineuse LED (3), et qui la focalise, dans une position prédéfinie, pour former une image d'une forme optiquement émise, qui est vue depuis la direction de l'axe optique de la source lumineuse LED (3); et d'un boîtier (2) qui loge la source lumineuse LED (3) et le premier élément de réfraction (4), et qui présente une ouverture d'émission lumineuse (2A) qui émet de la lumière qui a quitté le premier élément de réfraction (4) pour se diriger vers l'extérieur.
