Light for interior lighting with variable light intensity distribution has rotatable lamp partially coated or otherwise treated to be opaque or partly transparent on some surface regions

摘要

The light has a lamp that rotates within the light about its longitudinal axis and that is partially coated or treated in some other way so that it is opaque or partly transparent on some regions of its circumference. A manual controller is used to set subjectively preferable light distributions. An Independent claim is also included for a manual controller for individual setting of lamps and/or lights
