Abstract
A system and method of automatic cycling control for HID lamps, comprising a switching device for switching power to the HID lamp, a first timer operatively connected to the power switching device, and a second timer operatively connected to the power switching device, wherein the first timer starts timing when the power switching device powers the HID lamp and signals the power switching device to extinguish the HID lamp when the first timer counts to an operating time setpoint, and the second timer starts timing when the power switching device extinguishes the HID lamp and signals the power switching device to power the HID lamp when the second timer counts to a cooling time setpoint. If the lamp is turned off and on before the operating time setpoint is met, the system will reset and begin a new operating timing period.
