ABSTRACT:
Light sources having a holographic optical element incorporated in the envelope surrounding the radiation source provide efficient lighting of selected task area. Multilayer holographic optical elements may be employed in combination with known sources of white light such as incandescent filaments to form improved light bulbs, flourescent tubes and the like.
