Date Oct. 28, 1993A fluid optical system for focusing all entering light whatever its direction and incidence, and having an entrance surface through which the light enters. The optical system has a volume having an optical shape generated by a logarithmic spiral so that the focusing occurs for light beams entering the entrance surface from any direction through any point of the entrance surface. There flows in the optical shape a fluid which is maintained in forced circulation to form a fluid optical system, and which is forced to enter the optical system tangentially to the optical shape and adjacent to the entrance surface which is arranged so that initial circulation is tangential and laminar. Inside the optical system, the fluid has a centripetal rotation movement until it exits through a cone end of the optical shape, thus draining off calories.
