Abstract
The instant invention relates to an HID ballast and lamp tester, which provides visual indication of failure of either the ballast or lamp by continuously monitoring the status of the HID lighting system. The HID ballast and lamp tester detects and utilizes the voltage difference between the open circuit voltage and the operating voltage of the ballast to trigger visual indication of the open circuit voltage output of the ballast when the HID lamp has failed. The tester circuit comprises the ballast source, a full wave bridge rectifier and filter capacitor circuit, a voltage divider network circuit, a trigger circuit of a diac bi-directional silicon switch and a light emitting diode.
