ABSTRACT:
A method and system for standby lighting uses a power supply module and a standby lamp in conjunction with an HID lamp. The power supply module has a processor with smart trigger circuitry, soft start capability, overlap timer, and an advanced current sense algorithm. The power supply module continuously monitors the electronic ballast current to the HID lamp. If the current drops for a period of time, the power supply module supplies DC current to turn on the standby lamp gradually over a couple of seconds. The standby lamp is kept on while the processor checks for a rise in the electronic ballast current to a threshold current level for more than two seconds. Then, an overlap timer starts to count down for the time it takes for HID lamp to reach full intensity, approximately fifteen minutes. The standby lamp is turned off at the end of the count down.
