    • The invention relates to a self-supporting luminescent film (10), a phosphor-enhanced illumination system and to a method of manufacturing the self-supporting luminescent film. The self-supporting luminescent film comprises luminescent particles (20) and an organic polymer (30). The luminescent particles comprise luminescent material which is arranged for absorbing at least part of the impinging light impinging on the luminescent particles and for converting the absorbed light into converted light. The converted light has a predefined spectrum different from the impinging light. The organic polymer interconnects the luminescent particles to form the self-supporting luminescent film, wherein the self-supporting luminescent film comprises less than 10 weight percentage of organic polymer. The effect of the measures according to the invention is that the close packing of the luminescent particles generates a substantially uniform self-supporting luminescent film.

    • An illumination system (8) comprises an optical waveguide (18) which is made from optically transparent components and has four end faces (10, 10′). A light source (12) whose light is coupled into the optical waveguide (18) via one of the end faces (10), is situated opposite this end face (10). The optical waveguide (18) has a light guide (30). A number of fibers (34) are attached to a surface (32) of the light guide (30). The fibers (34) have birefringent properties. A preferred method of providing the birefringent properties is to stretch fibers (34) of a suitable polymer plastic material in their longitudinal direction. The light from the light source (12) will be polarized by the fibers (34) and polarized light will be outcoupled from the optical waveguide (18) via an exit surface (16). The illumination system (8) may be used for front or back lightning of LCD panels for e.g. mobile phones, PDA's, etc.

    • A phosphor-enhanced lighting device 100, a retrofit light bulb, a light tube and a luminaire are provided. The phosphor-enhanced lighting 100 device comprises a light source 116, a light exit window 102, a first light conversion element 112 and a second light conversion element 110. The light source 116 emits through its light emitting surface 118 source light 114 of a pre-defined color spectrum. The light exit window 102 emits light into an ambient of the phosphor-enhanced lighting device 100. The first light conversion element 112 comprises an inorganic luminescent material which absorbs a part of the source light 114 and converts a part of the absorbed light to light of a first color 104. The second light conversion element 110 comprises a first organic luminescent material which absorbs a part of the source light 114 and/or absorbs apart of the light 104 of the first color. The first organic luminescent material converts a part of the absorbed light to light of the second color 108. The second light conversion element 110 is optically arranged in between the light exit window 102 and the light emitting surface 118 of the light source 116. The first light conversion element 112 is optically arranged in between the second light conversion element 110 and the light emitting surface 118 of the light source 116. A gap 111 is present between the first light conversion element 112 and the second light conversion element 110.
