ABSTRACT A projection TV light controller is comprised of a plurality of blocks of material which are transparent to the light of a lamp, adjacent sides of the blocks being cooperatively shaped and being disposed adjacent to each other, to form a single light controlling element. The element is, shaped to surround a cylindrical region coaxial with a central axis of the element for containing the lamp. Light is conducted from the lamp in each of the three primary colours into respective ones of the blocks. Apparatus is associated with each block for creating video display light signals relating to a corresponding primary colour. The video display light signals of all of the primary colours are combined into a single light beam which is conducted out of the light controlling element. With the lamp being contained in a central region, it can be cooled either by convection, by a fan, or by a fused quartz fluid jacket around the lamp, maintaining the block cool and minimally subject to expansion or contraction.
