Abstract:
An illumination system for creating patterns of light on an adjacent surface comprising:a quasi point light source,a plate having a surface onto which patterns of light are to be formed, anda cylindrical refracting means surrounding the source radially and disposed adjacent to said plate, said cylindrical means including substantially axially elongated refracting elements the refracting portions of which are on the inner surface thereof and directly facing said source for refracting light traveling from said source into elongated spokes of light extending outwardly towards the surface on said plate which is adjacent said refracting means and creating spokes of light on such surface, said quasi point source being positioned with respect to said cylindrical means so that a substantial portion of flux from said quasi point source is refracted by said cylinder in a direction angularly offset from a radial direction towards the adjacent surface to produce visible patterns of light on the surface.
