Class Information
Number: 315/248
Name: Electric lamp and discharge devices: systems > Pulsating or a.c. supply > Induction-type discharge device load
Description: Systems wherein the load device in the system is a discharge device of the type which has an envelope (such as a glass bulb), containing an atmosphere of gas or vapor, the system including a magnetic coil mounted in inductive relation to the confined gas or vapor in the envelope and a generator of high frequency current connected to the magnetic coil so that the gas or vapor may be subjected to a high frequency field to ionize the gas or vapor within the envelope.
