ABSTRACT:
The lighting device contains a quartz tube and a UV production member. In addition to a main chamber for high intensity discharge, the quartz tube has an auxiliary chamber formed around the conductor in a first end section. The UV production member contains a probe and a coil surrounding the first end section. An end of the coil is connected to a conducting wire from the other end section of the quartz tube. The other end of the coil is connected to the probe whose tip penetrates through the first end section of the quartz tube into the auxiliary chamber and points to the main chamber. When a voltage is applied, electrons are shot from the tip of the probe into the gas in the auxiliary chamber, and UV light is thereby produced and directed into the main chamber for the enhanced activation of the lighting device.
