<p>A display apparatus (10) for an art work (12) includes a work support structure (20) on which the art work (12) rests; a power source (16); and an electric power circuit (18) containing a low heat, full spectrum light source (22), oriented toward the work (12) and a switch (24) wired to a sensor (26) which is preferably a conventional motion sensor oriented to detect the approach of a person, and upon detection of motion or heat to close the switch (24) and thereby activate the light source (22) to illuminate a work (12) resting on the support structure (20). Sensor (26) may be a passive infrared sensor for detecting the presence of a person or an animal within close proximity to the device. A lenticular image sheet (212) printed with a series of discrete elongate image segments (214) of the several two-dimensional images, and a translucent back panel (220) behind image sheet (212) and a light source (230) laterally adjacent to or behind back panel (220) oriented to cast light through image sheet (212).</p> |
