Abstract: A non-imaging optical system for operating on light using broken symmetry reflector surfaces (30). The theoretical upper limit for concentration of direct solar radiation at low latitudes with stationary concentrators is determined from the projected solid angle sampled by the apparent motion of the sun. Based on the fact that the solar radiation is not uniformly distributed within this projected solid angle, we derive higher concentrations which apply when rejecting the lower density radiation. Trough type systems, which have translational symmetry, cannot be ideal stationary concentrators. Efficiency is improved by using broken symmetry for surfaces of the reflector (30) and the light source or concentrator. We note that what applies to concentrators applies equally to reflectors for illumination.

Abstract: Un colector solar o sistema óptico sin imágenes que comprende: un reflector solar que tiene una superficie reflectante que tiene un eje longitudinal y una forma de canal simétrico que se extiende a lo largo del eje longitudinal, teniendo la superficie reflectante una estructura de simetría rota para proporcionar un intervalo de aceptación de espacio de fases no elíptico para el reflector solar que da como resultado una forma sustancialmente similar a una banda para la zona de aceptación durante un año solar con un vector de dirección kN que sustancialmente no varía con un vector de dirección kE.

Abstract: A nonimaging illumination optical device for producing a selected far field illuminance over an angular range. The optical device includes a light source, a light refracting medium means, and a family of light edge rays defined along a reference line with the refracting medium means defined in terms of the reference line as a parametric function R(t) where t is a scalar parameter position and R(t) = k(t) + Du(t) where k(t) is a parametErization of the reference line and D is a distance from a point on the reference line to the refracting medium means along the desired edge ray through the point.
