Exhibitions in musea and art galleries have a temporal character. The rendering of paintings and art pieces in general is highly dependent on the lighting conditions. Adapting constantly the lighting conditions in temporal exhibitions demands plenty of resources to satisfy the illumination of diverse form factors, and requires constantly different type of luminaires and/or accessories, which is not sustainable. Based on this motivation, a smart lighting projector has been conceived, whose angular distribution can be adapted to the shape and dimensions of the piece of art using computer vision and an electronically controlled projector with a resolution of 6deg in a range between 20deg and 65deg. The projector exhibits lighting characteristics that are apt for integration into museum lighting such a high CRI (>90), warm-to-neutral CCT and a smooth projection.
