摘要： A lighting device has a light source, a reflector dish with a central opening facing the light source, and a lens between the light source and the reflector dish. The lens is so arranged that light emitted from the source towards the central opening of the reflector dish is diffracted away from the central opening. The reflector dish is arranged to reflect light received from the source through the lens back past the lens and source.

摘要： In one method of and apparatus for varying the luminosity of illumination, each of a plurality of light sources has an on state in which it emits light and an off state in which it does not emit light. Each of the plurality of light sources is switched cyclically between the on state and the off state in a sequence over a cycle period. The switching sequence is selected such that the number of said light sources that are on is uniform over the cycle. The luminosity of the illumination is varied by varying the proportion of each cycle for which each light source is switched on.

摘要： Some embodiments provide luminance-preserving non-imaging backlights that comprise a luminous source emitting light, an input port that receives the light, an injector and a beam-expanding ejector. The injector includes the input port and a larger output port with a profile that expands away from the input port acting via total internal reflection to keep x-y angular width of the source image inversely proportional to its luminance. The injector is defined by a surface of revolution with an axis on the source and a swept profile that is a first portion of an upper half of a CPC tilted by its acceptance angle. The beam-expanding ejector comprising a planar waveguide optically coupled to the output port of the injector. The ejector includes a smooth upper surface, and a reflective lower surface comprising microstructured facets that refract upwardly reflected light into a collimated direction common to the facets.

摘要： An optical manifold for efficiently combining a plurality of blue LED outputs to illuminate a phosphor for a single, substantially homogeneous output, in a small, cost-effective package. Embodiments are disclosed that use a single or multiple LEDs and a remote phosphor, and an intermediate wavelength-selective filter arranged so that backscattered photoluminescence is recycled to boost the luminance and flux of the output aperture. A further aperture mask is used to boost phosphor luminance with only modest loss of luminosity. Alternative non-recycling embodiments provide blue and yellow light in collimated beams, either separately or combined into white.

摘要： An optical device for coupling the luminous output of a light-emitting diode (LED) to a predominantly spherical pattern comprises a transfer section that receives the LED's light within it and an ejector positioned adjacent the transfer section to receive light from the transfer section and spread the light generally spherically. A base of the transfer section is optically aligned and/or coupled to the LED so that the LED's light enters the transfer section. The transfer section can comprises a compound elliptic concentrator operating via total internal reflection. The ejector section can have a variety of shapes, and can have diffusive features on its surface as well. The transfer section can in some implementations be polygonal, V-grooved, faceted and other configurations.

摘要： A light source useful for a wide variety of lighting applications such as signage, architectural or automotive designs, as well as cosmetic and/or functional features for other products can be created by combining a light collector comprising a sheet of material having a fluorescent substance incorporated therein and an optical element juxtaposed adjacent the collector. Light incident on the collector induces fluorescence that is trapped by total internal reflection, concentrated, and radiated from an edge of the collector. The size of collector plate with respect to its thickness is such that it provides an intensified image along its edge that is readily visible during both daytime and nighttime. The optical element modifies the distribution of light output from an edge of the collector. The optical element is preferably configured to decrease divergence of light emitted from the edge. The optical element may also direct the light emitted from the collector above or below the plane of the collector. Preferably, this optical element comprises a non-imaging optical element. The collector design can also be varied as required. The collector for example can be bent to direct light upward or downward and may comprise a stack of layers or a series of segments that fluoresce at different wavelengths so as to produce multicolored output.
