Abstract
A picture light comprising a fitting (12,13) for mounting the light on a wall or picture. An arm (9) pivotally attached by pivot (10) at one end to the fitting (11) and at its other end by pivot (8) to hood or shade (1) in which at least one bulb (30) is housed. Adjustable light directing means are mounted in the hood (1) in the form of a pair of spaced vertical plates (40,44) movable axially of the hood (1) on rotation of knobs (5,6) and a pair of horizontal plates (50,50A) mounted on the vertical plates 40,44. Movement of the plates 40,44 axially along the hood (1) adjusts the depth of the pool of light (76) falling on the picture (75) whereas pivoting the horizontal plates (50,50A) adjusts the width of the pool of light (76).
