Abstract: The specification and drawings present a new apparatus such as a lighting apparatus, the apparatus comprising at least one LED (or OLED) module, configured to generate a visible light such as white light, and at least one component such as optical component comprising a compound consisting essentially of the elements neodymium (Nd) and fluorine (F), and optionally including one or more other elements. The lighting apparatus is configured to provide a desired light spectrum by filtering the generated visible light using the compound.

Abstract: In an embodiment, the disclosure provides a light source comprising at least one solid state light emitter. The light source, in operation, emits substantially white light having a Lighting Preference Index (LPI) of at least about 105, and this emission from the light source comprises a UV-violet flux of at least about 1%. Use of the lamps, light sources, and methods of the present disclosure may afford the ability to display linens and clothing under energy-efficient LED-based illumination, and may impart an effect to (especially white) clothing, that makes them look cleaner than under illumination by prior art LED lamps.

Abstract: An electrodeless or induction ceramic HID lamp includes a ceramic arc body having a generally spheroidal portion enclosing a discharge chamber and an induction coil received around a perimeter portion of the spheroidal portion. At least one leg extends from the spheroidal portion of the arc body. A mounting structure connects the arc body to the surrounding lamp assembly. In one arrangement, a mounting tube is received over at least a portion of the leg, and may further include a light transmissive shroud that also abuts with the induction coil to precisely locate the arc body relative to the coil. In another arrangement, first and second mounting members extend from spaced locations of the arc body, either as pins or legs extending from the spheroidal portion, or radially extending legs from an equatorial portion of the arc body.

Abstract: A high intensity discharge (HID) or ceramic HID lamp includes a main envelope having a gas fill that is selectively energized to produce visible light. An RF coil surrounds a light emitting portion of the main envelope, and an envelope extension or starting leg has a cavity that either contains a low pressure ionizable fill material to ionize at a level below the gas fill of the main envelope, or receives a high voltage potential conductor wire extending therethrough to serve as a starting assembly.

Abstract: An oblate spheroidal arctube body geometry provides for a significant reduction in stress cracks and results in lamps that operate at greater than 400 watts for extended periods of time leading up to greater than 20,000 hours. Preferably, the major diameter (OD) ranges between approximately 20 and 40 mm. Wall thickness (T) is preferably on the order of approximately 1.0 to 3.0 mm. An aspect ratio defined as AR (major axial dimension/minor axial dimension) is preferably between 1.1 and 2.0. A radius of curvature (R1) between the spheroidal portion and the leg of the arctube body preferably ranges from—approximately 3 mm to 12 mm or which can be expressed as a curvature 1/R1 ranging from 0.08 to 0.33 mm?1.

Abstract: A multi-turn coil formed from a single sheet of conductive material and the method of forming same eliminates the use of a weld. The multi-turn coil includes a single sheet of conductive material having at least a first turn in a first plane, and at least a second turn in a second plane, where the first plane is parallel to the second plane. An interconnecting fold interconnects the first and second turns, and any additional turns. The method of forming a multiple turn coil includes providing a continuous strip of conductive material having at least first and second turns extending through substantially 360° and formed in a first plane. The method further includes displacing at least the first turn from the first plane into generally overlapping, parallel relation with the second turn.

Abstract: A metal halide lamp (10) includes a discharge vessel (12) which may be formed of a ceramic material. The vessel defines an interior space (16). An ionizable fill (17) is disposed in the interior space. The ionizable fill includes an inert gas, mercury, and a halide component. The halide component includes an alkali metal halide, an alkaline earth metal halide component, and optionally at least one of a rare earth halide and a Group IIIA halide. The alkaline earth metal halide component includes at least one of a barium halide and a strontium halide. At least one electrode (18, 20) is positioned within the discharge vessel so as to energize the fill when an electric current is applied thereto. The lamp having a wall loading, when energized, which is sufficient to maintain an active tungsten halogen cycle.
