    Abstract: A light emitting device comprised of an electrodeless envelope (19') which bears a light reflecting covering (10') around a first portion which does not crack due to differential thermal expansion and which has a second portion which comprises a light transmissive aperture (12'). The light emitting device may further comprise an optical element (72) spaced from the envelope (19') and configured to reflect an unwanted component of light which exited the envelope (19') back into the envelope (19') through the aperture (12') in the light reflecting covering (10').

    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: A discharge lamp e.g. an electrodeless lamp bulb, comprises an envelope 44, fill 42, which emits light when excited, disposed in the envelope, a source of excitation power coupled to the fill and a reflector (e.g. a non-adherent reflecting jacket 44) disposed around the envelope and configured to reflect some of the light emitted by the fill back into the fill while allowing some light to exit (via aperture 48). The fill is capable of absorbing light at one wavelength and re-emitting the absorbed light at a different wavelength. The light emitted from the fill has a first spectral power distribution in the absence of reflection of light back into the fill. The exiting light has a second spectral power distribution with proportionately more light in the visible region as compared to the first spectral power distribution, wherein the light re-emitted by the fill is shifted in wavelength with respect to the absorbed light and the magnitude of the shift is in relation to an effective optical path length. The fill may comprise at least one substance selected from the group of sulfur and selenium and a fill density may be selected such that the first spectral power distribution comprises a substantial spectral power component in the ultraviolet region and the second spectral power distribution comprises a reduced spectral power component in the ultraviolet region as compared to the first spectral power distribution. An optical element 49 may be spaced from the envelope and configured to reflect an unwanted component of light which exited the envelope back into the envelope through the opening 48 in the reflector.
