The excitation circuit is effective for exciting the discharge medium to emit light with electromagnetic fields that are generated by the excitation circuit. A circuit is included for supplying electrical power from power mains to the excitation circuit. A transparent, electrically conductive coating is provided atop the vitreous envelope and is electrically connected substantially directly to one of the power mains at any given time. A transparent, electrically insulative coating is disposed atop the electrically conductive coating, and comprises a contiguous, inorganic glass layer. The insulative coating preferably has a minimum coating thickness of at least about 3.1 microns.

摘要： Disclosed is an electrodeless, low pressure gas discharge lamp. The lamp includes a vitreous envelope containing a metal vapor and an inert gas. The envelope is shaped with an external chamber for receiving an electrical excitation circuit. The excitation circuit is effective for exciting the metal vapor to emit light with electromagnetic fields that are passed through the vitreous envelope from outside, to inside, the envelope. A circuit supplies electrical power from power mains to the excitation circuit. A transparent, electrically conductive coating is disposed on the inner surface of the vitreous envelope for suppressing electromagnetic interference on the power mains. An electrically conductive coating is disposed on the outer surface of the vitreous envelope; it is capacitively coupled to the inner conductive coating, via a wall of the vitreous envelope, and is maintained at a suitable potential for suppressing electromagnetic interference on the power mains. The outer conductive coating comprises a matrix of a contiguous, inorganic, glass layer bonded to an exterior surface of the vitreous envelope, and conductive particles embedded in the matrix in a sufficiently dense manner to form a conductive coating.

摘要： A material is provided on the lead wires that support a filament of a fluorescent lamp assembly to inhibit arcing associated with filament burnout. The material comprises a glass that is non-alkaline. Another preferred arrangement is to incorporate a material into the assembly that will release an arc inhibiting gas in response to arcing of the lead wires. For example, a calcium carbonate or strontium carbonate material releases carbon dioxide to terminate undesired lead wire arcing.

摘要： 845 A method of producing a ceramic-metal-halide (CMH) discharge lamp having a monolithic seal between a sapphire (single crystal alumina) arc tube and a polycrystalline alumina end cap. The method includes the steps of providing an arc tube of fully dense sapphire and providing an end cap made of unsintered compressed polycrystalline alumina powder. The end cap is heated until it is presintered to remove organic binder material at a low temperature relative to the sintering temperature. The presintered end cap is placed on an end portion of the arc tube to form an interface therebetween. The assembled presintered end cap and arc tube are then heated to the sintering temperature wherein the end cap is fully sintered onto the arc tube and the sapphire tube grows into the end cap. A monolithic seal is formed at the previous interface between the end cap and the arc tube as the sapphire tube grows into the polycrystalline alumina end cap.

摘要： A solid state process for the bulk conversion of a dense polycrystalline ceramic body to a single crystal body has been accomplished by heating the polycrystalline material to a temperature above one-half of the melting temperature of the material but below the melting point of the material. As the process is a solid state process, no melting of the ceramic body is necessary to convert it to a single crystal. The process has been used to convert a dense polycrystalline alumina body (PCA) containing less than 100 wppm of magnesia to sapphire (single crystal alumina) by heating the PCA to temperatures above 1100.degree. C. but below 2050.degree. C., the melting point of alumina.

摘要： A high transmittance polycrystalline alumina arc tube for a metal halide discharge lamp is formed by treating an alumina arc tube material having a few percent of closed porosity in a two step process, which provides a high-transmittance arc tube. An initially porous arc tube is formed by extruding or die pressing individual components of the tube from a mixture which includes powdered alumina, assembling the components into an arc tube body, and then partially sintering the components to seal them together. The two step process includes hot isostatic pressing of the partially sintered arc tube and then chemically polishing the surface of the tube. The first, pressing step involves heating the alumina arc tube in an inert atmosphere, such as argon, at a temperature of 1600 to 1900° C. and a pressure of about 700 to 2100 kg/sq.cm. for from about one to three hours. This reduces porosity in the crystalline structure. In the second step, the surface of the tube is immersed in a flux comprising a molten alkali metal borate at moderately elevated temperatures, or coated with a flux material which is heated to form the flux, to remove surface imperfections. The finished arc tube has transmittance values which approach those of single crystal sapphire arc tubes.
摘要翻译：用于金属卤化物放电灯的高透光率多晶氧化铝电弧管是通过在两步法中处理具有几百个闭孔率的氧化铝弧管材料形成的，这提供了高透光率的电弧管。通过从包括粉末状氧化铝的混合物挤出或模压管道的各个部件形成最初多孔的电弧管，将组件组装成电弧管体，然后部分烧结组件以将它们密封在一起。两步法包括热等静压部分烧结的电弧管，然后化学抛光管的表面。第一个压制步骤包括在惰性气氛（例如氩气）中在1600至1900℃的温度和约700至2100kg / sq.cm的压力下加热氧化铝弧光管。约一到三个小时。这降低了晶体结构中的孔隙率。在第二步骤中，将管的表面在适度升高的温度下浸入包含熔融碱金属硼酸盐的焊剂中，或涂覆有加热以形成焊剂的焊剂材料，以去除表面缺陷。完成的电弧管具有接近单晶蓝宝石电弧管的透射率值。
