摘要： A wavelength converting member is provided, comprising a wavelength converting layer comprising an organic wavelength converting compound distributed in a matrix comprising an amorphous or semi-crystalline aromatic polyester wherein the aromatic polyester molecules are predominantly in a randomly oriented state, said wavelength converting member further comprising at least one support element. By avoiding uniaxial or biaxial orientation of the polyester matrix, the organic wavelength converting compound (organic phosphor) is well protected against photo-chemical degradation. The support element ensures the dimensional stability of the polyester matrix at temperature above the glass transition temperature.

摘要： A method for embedding data in light, wherein the method comprises the step of operating at least two light sources (A, B) arranged to emit light (101) having color coordinates (x, y) and luminous intensity (Y), wherein each light source is arranged to emit light (101a, 101b) which is distinguishable from the light of at least one other light source, and embedding data in the light emitted from the at least two light sources. The method further comprises the step of operating the at least two light sources such that the color coordinates of the light emitted from the at least two light sources are maintained over time within a first, bounded interval (115), and the luminous intensity of the light emitted from the at least two light sources is maintained over time within a second, bounded interval (116).

A composition comprising a transparent matrix comprising an anionic organic moiety, and metal cations dispersed in the matrix is disclosed. The anionic organic moiety and the metal cations form an organometallic complex, and wherein the metal cations are capable of forming transparent nano-crystals upon contact with an agent comprising at least one element selected from the group consisting of sulfur and selenium. Also an optical composition comprising a transparent matrix comprising an organic moiety residue, and unmodified nanocrystals is disclosed. Further, a method of preparing an optical composition comprising the steps of: providing a transparent matrix comprising an anionic organic moiety; dispersing metal cations into the matrix; and contacting the organometallic complex with an agent in order to in situ convert at least part of the metal cations into transparent nanocrystals.Preferably the matrix is a silicone or a polysiloxane and silicone rubber mixture.

摘要： The Invention provides a light source, a luminaire and a surgical illumination unit in which two narrow-band light emitters both emit light in a narrow spectral peak having a full-width-half-maximum equal to or smaller than 40 nanometers. Both of the narrow-band light emitters have a different central emission wavelength within a blue color-range, within a green color range or within a red color-range. At least one of the two narrow-band light emitters comprises a luminescent material for generating the narrow spectral peak. The light source is further configured such that a distance between the narrow spectral peaks of the two narrow-band light emitters prevents overlap of the narrow spectral peaks. Due to the individual narrow spectral peaks, a color contrast within one of the color-ranges is significantly enhanced.

摘要： The present invention relates to a lighting device (100) capable of creating dynamic color shadows. The lighting device (100) comprises multiple light sources (104, 105, 106) of different colors arranged to, together as a unit, emit white light. Furthermore, a contrast producing element (110) receives the emitted light and comprises portions (114) which may block light such that a shadow can be created on an object (122) behind the contrast producing element. A control unit (116) controls the light sources to modulate a spatial light spectral distribution if a selector is in an active state, or if the control unit is in an inactive state, white light is emitted by the lighting device. Thus, the lighting device is switchable between creating dynamic color shadows on objects while emitting white light, and only emitting white lights.
