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.

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 present invention is directed to horizontally burning formed-body arc tubes and arc tube blanks for high intensity discharge lamps. The bottom portion of the light emitting chamber of the arc tubes is flattened in an area between the electrodes to reduce the distance between the bottom wall of the arc tube and the arc, and to increase the surface area of the pool of condensed halides during operation of a metal halide lamp. The flattened bottom of the arc tubes may be generally planar, slightly arcuate longitudinally and/or transversely, or slightly v-shaped longitudinally and/or transversely. The top portion of the arc tube conforms generally to the shape of the arc during operation of the lamp.

An apparatus and method for achieving desired spectral emission characteristics in plasma lamps is disclosed. The apparatus and method use multi-layer thin film optical interference coatings to selectively reflect a portion of the light such that it can be absorbed in the plasma. The multi-layer thin film coating is applied to any surface of the lamp, which substantially surrounds the plasma. The number and thickness of the layers in the coating are selected to ensure that a significant portion of the selected light emitted from the plasma is reflected by the coating and absorbed by the plasma. The properties of the coating, reflectance, transmittance and absorption are determined as a function of plasma and lamp characteristics. These characteristics include the spectral emission characteristics of the plasma, the spectral absorption characteristics of the plasma, the physical dimensions of the plasma, the angular distribution of the light emitted from the plasma on the coating and the geometry of the coated surface.

A plasma lamp and method having high efficacy, high color rendering index, and a desirable correlated color temperature with improved color consistency from lamp to lamp. The lamp may include a vaporizable fill material comprising halides of sodium and scandium and a filter formed from a vitreous material containing a dopant. In one aspect, the filter is formed by a glass shroud containing neodymium oxide that reduces the transmission of yellow light.

Methods for improving the efficiency of infrared (IR) halogen lamps and IR halogen lamps having improved efficiency are disclosed. In a method of aligning a filament in a lamp body, the lamp body having the filament therein is rotated, and tubular end portions are heated and necked down which may assist in positioning the filament within the lamp and reduce end losses. IR halogen lamps formed from glass tubes having an OD less than 5 mm are also disclosed. The reduced diameter of the glass tubing increases the surface area for IR energy reflection and reduces end losses. Spuds or beads may be used to position the filament within the lamp.

The present application discloses high intensity discharge (“HID”) lamps, arc tubes, and methods of manufacture. The application relates to HID lamps, arc tubes, and methods of manufacture wherein a precise amount of fill gas may be contained in the light-emitting chamber of the arc tube so that the pressure of the fill gas contained in the arc tube at substantially room temperature may be precisely controlled at pressures greater than about one-half atmosphere.
