Abstract
Embodiments of the present invention provide for the rapid reignition of a high intensity discharge lamp. In one embodiment of the invention, an apparatus for a fast reigntion of a high intensity discharge lamp is disclosed. The apparatus is comprised of a ballast operatively coupled to the lamp that is configured to receive power from a power supply. The apparatus is also comprised of a timer circuit that enters a timing phase and produces a quantum of timing information when the lamp ceases receiving power from the power supply. This timer circuit does not require external power during the timing phase. The apparatus is additionally comprised of a control circuit that receives the timing information and permits the ballast to reignite the lamp based on the information.
