Title:
ELECTRODELESS DISCHARGE LAMP LIGHTING DEVICE
Document Type and Number:
Japanese Patent JP3812234
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a high-frequency circuit from being damaged without using a high-pressure-proof component, even when an external lightning surge voltage such as a lightning surge is impressed between a ground and an electric power source output terminal.
SOLUTION: A positive electrode terminal of a direct current power source 1 is grounded via the first impedance element Z1, an external conductor 2b of a coaxial cable 2 connected to the negative electrode terminal of the power source 1 is grounded via the second impedance element Z2. A high-frequency circuit is prevented thereby from being damaged without using a high-pressure- proof component, even when an external lightning surge voltage such as a lightning surge is impressed between a ground and an electric power source output terminal.
