Abstract

1,021,351. Lamp shades. G. MOCKER. Aug. 10, 1964 [Jan. 7, 1964], No. 32422/64. Heading F4R. A variable colour lamp comprises a source 8 of white light, an opaque screen 9 surrounding the source and cut away over part of its periphery, a transparent screen 3 which can be rotated about the source concentrically to the screen 9 and is subdivided peripherally into at least two differently coloured sections, and a colourless lampshade 2 arranged concentrically around, and at a distance from, the screens. The lampshade is made of highly refractive frosted material such as quartz glass, and is almost uniformly illuminated by light reflected in the space between the shade and the screen 3. A further fabric, wax paper or frosted glass lampshade may be arranged around the shade 2. The screen 3 is rotated by means of a knob 5 projecting through the cover 6 of the lampshade. In modifications the knob projects through the side of the lampshade or the base 1 of the lamp. Two independently rotatable transparent screens mounted one within the other may be provided to increase the range of colours available. The screen 9 may be in the form of an opaque covering over the surface of the light bulb 8, or may be disposed outside the screen 3.
