ABSTRACT:
A lamp shade including a plurality of light deflecting elements. The light deflecting elements are rotatably mounted so as to be independently rotated with respect to the frame and one another. In one embodiment the light deflecting elements are mounted end to end to allow vertical variation in light intensity and direction. In another embodiment the light deflecting elements are both horizontally and vertically disposed to increase versatility in both appearance and lighting effect. Thus, the lamp shade which advantageously allows the light to be directed in accordance with the particular area in which the light fixture is placed, both to shield the user's eyes and to direct light where it is most needed. At the same time, because the light emanating from the light source can be efficiently used in that it can be directed to the areas in which it is desired or required in an amount determined by the user, a lesser wattage light source can be effectively used to light the area in the vicinity of the light source to the same extent as a higher wattage light source in a conventional shade.
