    Abstract: A light pipe (4) includes a conduit (6) configured to receive light at one end and to distribute the light along its length. The conduit (6) includes a combination of specular and diffuse reflecting surfaces (8) arranged to pass a portion of the light down the light pipe (4) primarily with specular reflection and to emit a portion of the light out of the light pipe (4) primarily with diffuse reflection. The reflecting surfaces (8) are substantially parallel to a longitudinal axis of the light pipe (4). A plurality of conduit (8) may be used to control the light distribution characteristics of the light pipe (4). The conduit (6) may be made from inexpensive plastic sheet materials.

    Abstract: A high frequency inductively coupled electrodeless lamp includes an excitation coil with an effective electrical length which is less than one half wavelength of a driving frequency applied thereto, preferably much less. The driving frequency may be greater than 100 MHz and is preferably as high as 915 MHz. Preferably, the excitation coil is configured as a non-helical, semi-cylindrical conductive surface having less than one turn, in the general shape of a wedding ring. At high frequencies, the current in the coil forms two loops which are spaced apart and parallel to each other. Configured appropriately, the coil approximates a Helmholtz configuration. The lamp preferably utilizes a bulb encased in a reflective ceramic cup with a pre-formed aperture defined therethrough. The ceramic cup may include structural features to aid in alignment and/or a flanged face to aid in thermal management. The lamp head is preferably an integrated lamp head comprising a metal matrix composite surrounding an insulating ceramic with the excitation integrally formed on the ceramic. A novel solid-state oscillator preferably provides RF power to the lamp. The oscillator is a single active element device capable of providing over 70 watts of power at over 70 % efficiency. Various control circuits may be employed to match the driving frequency of the oscillator to a plurality of tuning states of the lamp.

    Abstract: An electrodeless microwave discharge lamp includes a source of microwave energy, a microwave cavity, a structure configured to transmit the microwave energy from the source to the microwave cavity, a bulb disposed within the microwave cavity, the bulb including a discharge forming fill which emits light when excited by the microwave energy, and a reflector disposed within the microwave cavity, wherein the reflector defines a reflective cavity which encompasses the bulb within its volume and has an inside surface area which is sufficiently less than an inside surface area of the microwave cavity. A portion of the reflector may define a light emitting aperture which extends from a position closely spaced to the bulb to a light transmissive end of the microwave cavity. Preferably, at least a portion of the reflector is spaced from a wall of the microwave cavity. The lamp may be substantially sealed from environmental contamination. The cavity may include a dielectric material is a sufficient amount to require a reduction in the size of the cavity to support the desired resonant mode.

    Abstract: A lamp bulb (1) includes a light transmissive envelope (2), a fill material disposed inside the envelope including a rare earth metal which forms a plas ma discharge when excited, and a coating (3) disposed on an interior surface of the envelope which inhibits reaction between the plasma discharge and the envelope (2), wherein the coating (3) comprises an oxide of the same rare earth metal of the fill material. A process for coating the interior of a la mp bulb envelope (2) includes preparing a sol gel solution having a precursor o f the desired coating, introducing the sol gel solution into a lamp preform, distributing the sol gel along an interior surface of the bulb, and drying a nd firing the sol gel to obtain the coated bulb.

    Abstract: A discharge lamp bulb includes a light transmissive envelope and at least one conductive fiber disposed on a wall of the envelope, where the fiber has a thickness of less than 100 microns. The lamp may be either electrodeless or may include internal electrodes. Suitable materials for the fiber(s) include but are not limited to carbon, silicon carbide, aluminum, tantalum, molybdenum, platinum, and tungsten. Silicon carbide whiskers and platinum coated silicon carbide fibers may also be used. The fiber(s) may be aligned with the electrical field, at least during starting. The lamp preferably further includes a protective material covering the fiber(s). For example the protective material may be a sol gel deposited silica coating. Noble gases inside the bulb at pressures in excess of 300 Torr can be reliably ignited at applied electric field strengths of less than 4x10 V/m. Over 2000 Torr xenon, krypton, and argon respectively achieve breakdown with an applied field of less than 3x10 V/m.
