Abstract
A projection system includes a recessed projection fixture that includes a lighting module configured to emit a light and a projection module configured to project an image. The light emitted by the lighting module is used for projecting the image and for illumination. The projection system further includes a sensor, where the projection module projects the image in response to an occupancy detection by the sensor. The recessed projection fixture is oriented to direct the image toward a surface below the recessed projection fixture.
