Abstract
The invention provides a system of pinpoint lighting comprising a plurality of lens units supplied with light by the separated tail ends of a fiber optic cable of which the remote input end is supplied by a simple light source. The lens provides separate beams of light which are directed at individual articles such as individual items of jewelry in a display case. Each lens unit is adjustable so that the beam direction can be varied on the one hand and the beam intensity can be varied on the other hand.
