1. An illumination device comprising:
an image frame buffer configured to store image frame buffer data received from an external source;
a standby image buffer configured to store at least one set of default image data; and
a light emitting diode (LED) array configured to project light according to a pattern and intensity at least partially dependent on at least one set of data selected from the image frame buffer data and the at least one set of default image data dependent on whether a current set of image frame buffer data is received from the external source within a predetermined time from a previous set of image frame buffer data from the external source, pixels of the LED array being addressable such that the pixels are selectively controllable at least one of individually and in blocks of pixels based on the at least one set of data selected from image frame buffer data and the at least one set of default image data.
