A unitary hollow device adapted for covering a source of lightwave energy, apparatus comprising the combination of such device and such energy source, and a system comprised of a combination of the apparatus and a portable directional receiver. The energy source can be as simple as one or more light bulbs. However preferably the combination involves use of an array of light emitting diodes for transmitting infrared signals from fixed installations to be picked up by print-disabled persons with hand-held receivers which convert the signals to intelligible communication to enable the persons to be guided to desired locations. The device protects the energy source from accumulation of dust and other debris yet is configured to provide little, if any, interference with the transmission of the emitted signals. The device also conceals the energy source to thereby diminish theft and vandalism.
