摘要： An efficient downlight system for directing light includes a light source and a generally tubular, hollow coupling device with an interior light-reflective surface for receiving light from the source at an inlet and transmitting it as a generally diverging light beam through an outlet. The coupling device is shaped in accordance with non-imaging optics and increases in cross sectional area from inlet to outlet in such manner as to reduce the angle of light reflected from the surface as it passes through the device. A thermal-isolating region has an inlet positioned in proximity to an outlet of the coupling device and has an outlet for passing light to an optical member. An arrangement for splitting the light from the outlet of the thermal-isolating region comprises a plurality of light guides. Each light guide includes an inlet end for receiving light from the thermal-isolating region and an outlet end for directing light to a remote location. The inlet ends are substantially coplanar with each other and form a substantially solid shape. The coupling device and thermal-isolating region are shaped so as to distribute a respective, substantial (i.e., useful) amount of light to each of the plurality of light guides. Efficiencies of about 30 lumens per watt may be achieved.

摘要： An efficient arrangement for coupling light between a light source and at least one light guide comprises a light source having a bulbous region and electrical in-leads extending into the bulbous region. A generally tubular, hollow coupling device with an interior light-reflective surface receives light from the source at an inlet and transmits it to an outlet. The coupling device increases in cross sectional area from inlet to outlet in such manner as to reduce the angle of light reflected from the surface as it passes through the device. A thermal-isolating region has an inlet positioned in proximity to an outlet of the coupling device and has an outlet for passing light to an optical member. The thermal-isolating region comprises one or more members. The foregoing can achieve high efficiency and considerable compactness while using a non-“point-like” light source.

摘要： A light delivery system includes a light source. A first generally tubular, hollow coupling device with an interior light-reflective surface receives light from the source at an inlet and transmits it to an outlet. The coupling device increases in cross sectional area from inlet to outlet in such manner as to reduce the angle of light reflected from the surface as it passes through the device. A thermal-isolating region has an inlet positioned in proximity to an outlet of the coupling device and has an outlet for passing light to an optical member, the thermal-isolating region comprising one or more members. A waterproof container for the light source and coupling device has an aperture allowing light to pass out of the container. The aperture is sealed in part by a portion of a member of the thermal-isolating region. Advantageously, the system can be buried beneath the surface of the ground. This avoids the problem of people or equipment colliding with the system. The components in the sealed container are protected from intrusion by wildlife or deterioration from dirt and dust. In some embodiments, the container may be free of a fan, reducing the complexity and noise of the system.

摘要： A lamp driver circuit is presented herein for driving a lamp circuit with an AC squarewave voltage at a relatively high frequency. The driver circuit includes a self-oscillating half-bridge circuit having a pair of input terminals connected across a DC voltage supply, which may be obtained from rectifying an AC voltage signal, and a pair of output terminals connected across a lamp circuit including a lamp, either a resistive lamp or a gaseous discharge lamp, to be energized. The circuit also includes a pair of capacitors connected together in series across the input terminals and having a junction therebetween connected to a first one of the output terminals. The bridge circuit also includes first and second switching transistors connected together in series across the input terminals. A transformer is provided having first and second windings thereon respectively connected to the first and second switching transistors for alternately applying forward biasing base drive current to the first and second transistors. A third winding on the transformer is connected in series from the junction of the two transistors to a second one of the output terminals for purposes of supplying a squarewave voltage across the output terminals for driving the lamp circuit. A starter circuit serves to start the half-bridge circuit by initially turning on one of the switching transistors in such a manner that while one transistor is being forward biased into conduction, the other transistor is reverse biased.

摘要： A jacketed metal halide discharge lamp combining a miniature arc tube containing sodium iodide and a standby filament within an outer envelope, is provided with a glass sleeve around the arc tube. The glass sleeve is preferably connected to a point of potential which is positive relative to the arc tube, suitably the anode when the arc is operated on d.c. The glass sleeve prevents sodium loss from the arc by trapping ultraviolet light and by shielding the arc from photoelectrons. The sleeve serves also to reduce color shift when the arc tube is switched over from "high" to "low", and to protect the outer bulb in the event of arc tube rupture.

摘要： A luminaire with improved lateral illuminance control comprising a light pipe with a longitudinal center is disclosed. A light-extraction means applied to a radial swath of the light pipe has a longitudinal portion having dimension along its length, centered about a slice on the light pipe longitudinally; said slice being orthogonal to the longitudinal center and located in a propagation plane through which light propagates to a virtual target area intersecting the propagation plane. The light pipe intervenes between the radial swath and the target area. A first average efficiency point of the light-extraction means corresponds to the minimum distance to the target area being at least approximately 20% less than a respective, second average efficiency point corresponding to a respective maximum distance to such area. The light-extraction means efficiency varies from the first average efficiency point to the second average efficiency point though more than one non-zero value.

摘要： An efficient system for directing light comprises a light source and a generally tubular, hollow coupling device. The coupling device has an interior light-reflective surface for receiving light from the source at an inlet and transmitting it as a generally diverging light beam through an outlet. The device is shaped in accordance with non-imaging optics and increases in cross sectional area from inlet to outlet so as to reduce the angle of light reflected from the surface as it passes through the device. The foregoing system provides a discharge-based directional light source that can be of the size of a directional halogen source (e.g., an MR16 or MR 11 lamp) while substantially preserving the discharge efficiency, light-output capacity and lifetime of discharge-based sources. This results from the coupling device that provides light with good spatial uniformity in light intensity and color. Embodiments of the invention can simply split the light to multiple (e.g., two) destinations with substantially the same efficiency.
