ABSTRACT:
A light director has an elongated, hollow, opaque open-ended shield. The shield slips over the glass housing of a light bulb. A pair of small apertures on the side of the shield receive portions of the glass housing in a sliding engagement which provide for the shield to be oriented in several angular positions. A plurality of flat, spaced apart slats extend across one open end and function to cause the light to exit in generally parallel beams.
