摘要： Elongated lighting system comprises an elongated light pipe having first and second ends, with light supplied to those ends by at least one light source, via first and second light couplers that condition light to increase reflections within the light pipe. Light-extraction structure on the light pipe extracts light from the side of the pipe. An indentation in the light pipe has a depth and has surfaces oriented with respect to the pipe so as (1) to redirect light from the first light source that reaches the indentation after passing once through a plane adjacent the indentation, back through the plane and towards the first end; and (2) to sufficiently increase the average angular distribution of light reflected from the indentation and passing back through the plane as would cause at least 50 percent more reflections of the foregoing light within the pipe in the absence of the light-extraction structure.

摘要： An elongated LED lighting arrangement comprises an elongated fiberoptic light pipe having an exteriorly facing sidewall between its ends. The light pipe is constructed to promote TIR of light between the ends. A first LED light source is tuned to efficiently provide light within a wavelength range to the pipe. Light-extracting means are applied along the light pipe along the main path of TIR light propagation, and comprise down-converting means tuned to efficiently convert light rays from the LED light source within the wavelength range to lower-energy light rays at respectively longer wavelengths and light-scattering means for extracting from the pipe some light rays within the wavelength range without changing the wavelengths of the foregoing light. The light emitted by the down-converting means and the light-scattering means intermix to produce light, the majority of which has a composite color determined by the foregoing light emitted and the foregoing light extracted.

摘要： An LED lighting system, with first and second types of LEDs of different efficacies, has a reduced-power usage mode. A control system independently controls first and second control groups of first and second types of LEDs, respectively. The control system has one or more modes including a reduced-power usage mode for decreasing the overall power consumption of the lighting system while maintaining a light level of at least a predetermined percentage of the level present when the first control group of LEDs operates at a power level between less-than-full power and full power and the second control group is off. The predetermined percentage is 50. The control system decreases the overall power consumption of the lighting system in the reduced-power usage mode by turning off or dimming the first control group and turning on the second control group to at least some extent.

摘要： A hub arrangement for mounting light pipe to receive light includes a light pipe hub for mounting at least one light pipe, with a plug-and-socket arrangement. The plug-and-socket arrangement includes (i) a socket in the light pipe hub for receiving a plug, and (ii) a plug for mounting a light pipe end that is to receive light. A fore end of the plug is receivable within the socket. The plug has a channel for receiving the light pipe through an aft end of the plug. The hub arrangement may also include, if desired, a rod hub for mounting at least one thermally isolating, light-collection rod for receiving light from a light source. The hub arrangement allows easy and rapid coupling of light pipe to an illumination source, using a “plug-and-socket” feature. The hub arrangement may incorporate several safety features to prevent premature light pipe failure.

摘要： Improved side-light distribution systems are disclosed. In one embodiment, an efficient side-light distribution system includes a LED light source; a light coupler for receiving light from the LED light source at a first end and providing light at a second end to an elongated light pipe, and the elongated light pipe receives light from the LED light source at a first end and transmitting the light towards a second end. The coupler transforms at least the angular distribution of at least 70% of the light from the LED light source into an appropriate angular distribution needed for total internal reflection at a second end within the elongated light pipe. The light coupler includes a light-extraction means between the first and second ends of the light coupler for extracting light out of a side of the light coupler. At least part of the light within the light pipe is extracted out of a side of the light pipe, between the first and second ends of the light pipe, by a light-extraction means.

摘要： An adjustable-aim light pipe fixture, comprising a generally spherical eyeball for receiving an end of a light pipe is disclosed. The eyeball has a longitudinal axis coincident with a longitudinal axis of that portion of the light pipe that is received in the eyeball. A socket holds the eyeball. The socket comprises a first retainer ring and a second retainer ring. Each retainer ring has an interior surface with contact points to an outer surface of the eyeball. The first and second retainer rings are oriented with respect to each other so as to hold the eyeball in a fixed position when the first and second rings are pressed towards each other. Clamping structure clamps the first and second rings against each other in such manner as to hold the eyeball in fixed relation to the first retainer ring.

摘要： A fiberoptic lighting system has a light source with a bulbous section and a plurality of plastic light pipes having substantially circular cross sections. A collector has an inlet for receiving light from the light source and an outlet. The collector performs an area-to-angle conversion on light it collects from the light source. A plurality of rods receives light from the collector and passes such light to the plastic light pipes, while thermally isolating the plastic light pipes from the light source. A perimeter of an outlet of the collector has a plurality of shaped portions, each associated with, and each substantially shaped the same as, a substantial portion of an associated perimeter of a respective one of the plurality of rods. The foregoing system delivers a higher percentage of light from a light source into multiple light pipes than in a prior art system.
