    • 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.
    • 公开了一种无电极低压气体放电灯。 该灯包括含有金属蒸气和惰性气体的玻璃质外壳。 外壳成形为具有用于接收电激励电路的外部室。 励磁电路有效地激发金属蒸气发射光,其中电磁场通过玻璃密封从外部到内部通过信封。 电路将电力从电源提供给励磁电路。 透明的导电涂层设置在玻璃质封套的内表面上,用于抑制电源上的电磁干扰。 导电涂层设置在玻璃体外壳的外表面上; 其通过玻璃体外壳的壁电容耦合到内部导电涂层,并且被保持在用于抑制电力电源上的电磁干扰的适当电位。 外部导电涂层包括结合到玻璃体外壳的外表面的邻接的无机玻璃层的基质和以足够密集的方式嵌入基质中的导电颗粒以形成导电涂层。
