ABSTRACT:
An illuminating system for projecting light upwardly from a light chamber without being directly visible to nearby observers. The system has a cavity disposed above the light chamber forming a vertical passageway for light. The cavity has a light blocker in the passageway for restricting the upward passage of light such that the restricted light beam passing through the cavity does not substantially impinge upon the inner surface of the cavity walls near their upper ends.
