Elements moving always in one plane, rotating; actuating - Apparatus for producing varying colour effects for projection upon a picture, screen, vases &c. comprises a casing 1 containing an electric lamp 6, the hot air convection currents from which actuate a fan-wheel 10. The spindle 11 of the wheel actuates a coloured disc 7 located above a glazed opening 14 in line with an upper opening 15 provided with an adjustable mirror 16 for reflecting the light beam at any desired angle upon an object to be illuminated. The disc 7 is secured by a clip to its supporting spindle and may thus be readily changed.
