Moreover, this gas discharge mechanism has negative resistance characteristics. If the electrodeless lamp is directly connected to the voltage source, it will be burned due to the current rapidly increasing to exceed the rated current of the electrodeless lamp. Therefore, an external resistor must be installed on the lamp holder. Ballast, connect an external ballast in series to the circuit between the lamp holder and the coupler to stabilize the working current of the lamp. However, adding an external ballast to the lamp holder will inevitably generate a circuit on the lamp holder The cost of change and the modification cost of other assembly structures, and the addition of complex additional work procedures, thus increasing the installation cost of the lamp.
