Abstract: A viewing angle colour sensitive lighting accessory comprising a sheet member (1) capable of transmitting light, emitting from a visible light source (2), forwardly towards an area from which light is to be perceived, at least one optical interference multilayer coating (3) on the sheet member and means (4, 6) for securing the sheet member to the light source. The coating has a transmittance which is a function of wavelength and angle of incidence, and in most instances, of state of polarization of the visible light thereto so that the light perceived from the light source has a particular colouration and, if desired, polarization at a particular viewing angle to the coating. The light source may be, for example, an incandescent light source or a light guide, or any other luminaire. The means for securing the sheet member to the light source preferably removably secures the sheet member thereto.

Abstract: The light guide apparatus described will guide a beam whose rays have a predetermined phase space distribution with a maximum deviation angle θ max in a first plane perpendicular to the beam axis. The guiding apparatus includes an optical system positioned at a distance L/2 from the first plane for receiving light from the edge of the spreading beam along an edge of width Ltan θ max and for diverting the light towards the beam axis to reproduce the predetermined spatial distribution in a second plane perpendicular to the beam axis at a distance ℓ from the first plane. The optical system can be made from annular or cylindrical, regular or fresnel lenses. A number of systems may be sequentially mounted to guide a beam along any desired distance with in a straight line or perpendicular to its original direction.
