The invention describes a mercury-free high intensity gas-discharge lamp (1) comprising a discharge vessel (5) enclosing a fill gas in a discharge chamber (2) and comprising a pair of electrodes (3, 4) extending into the discharge chamber (2), for which lamp (1) the fill gas in the discharge chamber (2) is free of zinc iodide, and the fill gas includes a halide composition comprising sodium iodide and scandium iodide to a combined proportion of at least 30 wt% and at most 95 wt%, and thulium iodide, to a proportion of at least 5 wt% and at most 70 wt%.
Abstract:
A gas discharge lamp (1) equipped with a gas discharge vessel (2) enclosing a gas filling, said gas filling comprising a chalcogen selected from the group of sulfur, selenium or tellurium or a compound thereof, and with means for igniting and maintaining a gas discharge, comprising an electrode assembly (6-9) disposed in the discharge vessel, the electron-emissive material (9) of the electrode assembly comprising iridium or an alloy of iridium, providing a long-lived, efficient, compact, and high intensity white light source for applications such as general and professional illumination.
Abstract:
Apparatus for inducing electrically charged alignment changes in biological tissue includes a generally flat translucent cavity containing a volume of gas that includes water vapor, carbon dioxide and other similarly common molecules that is charged along one surface by a sequence of pulses of electrical charge each of a potential sufficient to excite the common molecules to a higher state. The opposite side of the cavity is then conformed for intimate contact with the skin of a person, thus communicating the right hand spin electromagnetic pulses associated with each excitation level change into the tissue. A pulsed coil is then provided in an alignment generally parallel to the plane of the cavity to polarize the clockwise electromagnetic emissions associated with the changes in the excitation states.
Abstract:
The invention relates to a metal-halide lamp comprising a discharge vessel (3) with a ceramic wall, the discharge vessel (3) enclosing a discharge space which contains an ionizable filling, which filling contains a quantity of halide of Na, Ca and Tl in addition to Hg. According to the invention, the ionizable filling comprises CaI 2 in a molar quantity which lies between 20 and 50% of the total molar quantity of the halides. Preferably, the molar quantity of CaI 2 lies between 25 and 35% of the total molar quantity of the halides.
Abstract:
A discharge lamp comprising a transparent envelope, a discharge medium within the envelope, and a means for causing a discharge in the discharge medium uses a discharge medium containing an active component consisting of molecules including nitrogen. For instance, N 2 molecules or CN radicals in an inert gas are suitable. A mercury-free lamp is thus produced in which a significant proportion, preferably the majority, of the emissions from the discharge medium are in the desirable wavelength range 300 and 400 nm.
Abstract:
A light bulb (1) includes a pair of electrodes (3), and I/S is less than 20 A/mm , where S is the cross section of the point of the electrodes (3) and I is the current that flows between electrodes (3) at rated power for the bulb. Since this condition prevents the light bulb (1) from blackening or the increase in the lamp voltage, which can occur due to the evaporation of the electrodes with time, a long service life can be achieved.
Abstract translation:灯泡(1)包括一对电极(3),I / S小于20A / mm 2,其中S是电极(3)的点的横截面,I是电流 在电极(3)之间以灯泡的额定功率流动。 由于该状态可防止由于电极随时间的蒸发而发生的灯泡(1)变黑或灯电压的增加,因此可以实现长的使用寿命。
Abstract:
An electrodeless lamp includes a stationary bulb (10) containing a fill for producing a discharge, the fill has a primary radiating material which ordinarily produces an unstable discharge in the absence of bulb rotation. The fill further includes an alkali metal in an amount sufficient to stabilize the discharge without bulb rotation. The alkali metal may be, for example, cesium bromide. Preferably, the fill is excited by a non-stationary electric field (E, E1) such as, for example, a circular polarized electric field.
