Title:
LIGHTING DEVICE FOR ELECTRODELESS DISCHARGE LAMP, ELECTRODELESS DISCHARGE LAMP AND PHOTOCHEMICAL TREATMENT DEVICE
Document Type and Number:
Japanese Patent JP2001217089
Kind Code:
A
Abstract:
To restrain fluctuation of supplied power and enable a suitable power supply.
The lighting device for an electrodeless discharge lamp is provided with an electrodeless discharge lamp 4 of induction coupling, a high-frequency power source 1, and an output circuit 2 furnished with excitation coil for supplying the above electrodeless discharge lamp with power obtained from the above high-frequency power source 1, and it is so constructed that the absorption confficident Xa/Ra is to set Q of the above excitation coil 3 nearly at minimum during lighting of the above discharge lamp, when equivalent discharge reactance is set as jXa.
