ELECTRODELESS LOW-VOLTAGE MERCURY-VAPOR DISCHARGE LAMP

摘要

PURPOSE: To provide an electrodeless discharge lamp containing a low pressure mercury lamp which has a simple structure and reliability. CONSTITUTION: A discharge chamber 1 of an electrodeless discharge lamp containing the pressure mercury is provided with a core 4 of magnetic material and a coil 5 wound around the core 4, and this coil 5 is connected with a unit 6 for a high-frequency power source. A transparent conductive layer 10 for protecting an obstacle to a high frequency is prepared at an outside of the discharge chamber 1, an the conductive layer 10 is connected with a principal power source through a conductor 11. The conductor 11 is provided with one capacitance or more 12 for such a safety protection as someone touches the conductive layer 10 in operation of the discharge lamp 1.
