<p>An integrated ballast module (200) for activating a High Intensity Discharge (HID) light bulb (30), which comprises an activation signal receiving means (60), an activation signal adapting means (212) comprising a multi-polarity circuit which accept the polarity of the incoming activation signal current, a process controller (204), a receiving means (40) for input power, a delayed switching means (206), a switch-mode power supply (SMPS) section (208), a converting and filtering section (210) and a transmitting means (50) for output power wherein a light activation command signal received through the activation signal receiving means (60) is adapted and sent to the process controller (204) which starts the delayed switching means (206) and the generating of AC current by the SMPS (208) to be transmitted to one or more HID light bulbs (30). Additionally the module contains a circuitry design to diagnose problems encountered in the ballast module (200) installation and operation such as faulty input connections, low battery, faulty bulb and faulty output connections.</p> |
