An electrodeless lamp arrangement powered by RF energy. The lamp arrangement having an envelope that is rotated and most importantly the envelope forms the center of a coaxial arrangment used to transfer the RF energy into the envelope.
Abstract:
A lamp for emitting in the visible portion of the spectrum, which utilizes a fill which includes a selenium and/or a sulfur containing substance. The lamp has superior performance characteristics, including long lifetime and excellent color rendition. The bulb may be either electrodeless or electroded, and may contain additives for emphasizing a desired spectral region.
Abstract:
The spectral energy characteristic of a discharge lamp is controlled by changing the density of the fill substance. The spectral characteristic can be shifted while substantially maintaining its shape by changing the density of the fill. A sulfur or selenium containing discharge lamp which is operated at a pressure of at least about 1 atmosphere contains a low ionization potential substance in the fill. Characteristics which are improved are one or more of spatial color uniformity, extinguishing characteristics, and bulb starting reliability. Particular substances which are added to the fill are alkalai metal containing substances, III B metal containing substances, and alkaline earth metal containing substances. When light is reflected back into the bulb, the light which is re-emitted is stronger in the higher wavelengths.

Abstract:
A microwave powered ozone producing system comprising a housing defining a microwave cavity having a volume Vo, an inlet and exhaust ports which communicate with the microwave cavity. Disposed within the microwave cavity and uniformly distributed therewithin are a number N of ozone producing lamps, each of which has a diameter D, a length L, and a nominal power p. Communicating with the microwave cavity is a microwave magnetron generator having a microwave power P and producing microwaves having a wavelength .lambda.. Electrically connected to the generator is a power supply. The optimal operating condition for the system to maximize the ultraviolet output and longevity of the lamps and minimize system power consumption is governed by the relationships:Vo.gtoreq.V min 1 wherein V min 1=8 .pi..lambda..sup.3 /3;Vo.gtoreq.V min 2 wherein V min 2=.pi.(D+1).sup.2 N L/4; and ##EQU1## wherein V min is the larger of V min 1 and V min 2, and k is a constant with a value in the range of 0.3.ltoreq.k.ltoreq.3, and .pi.=3.14.

Abstract:
An electrodeless high intensity discharge lamp includes an electrodeless lamp capsule, first and second electric field applicators positioned so that the lamp capsule is between the electric field applicators, and a planar transmission line. The planar transmission line couples high frequency power from an input to the first and second electric field applicators and has a gap with in which the lamp capsule is positioned. A field symmetrizing conductor, preferably a thin wire, is located in an open side of the gap and is electrically connected to the ground plane of the planar transmission line. The field symmetrizing conductor is positioned such that the electric field in the lamp capsule is substantially symmetrical with respect to the lamp axis and is substantially colinear with the lamp axis.
Abstract:
An electrodeless lamp which operates with a high efficiency and with a lower cooling requirement. The bulb is rotated at a high speed which results in a substantial increase in efficiency. Because more of the input energy is converted to light, and less to heat, the pressure of the cooling fluid source may be reduced, resulting in a less noisy system.
