Abstract
In a method of driving a lamp using a lamp control circuit, the lamp control circuit comprises a communication circuit and a lamp driving circuit. The lamp driving circuit is configured to drive a lamp in accordance with a number of lamp operating parameters. The method comprises providing a lamp operating parameter to a memory of the communication circuit; providing a supply voltage to the lamp driving circuit; and supplying the lamp operating parameter from the memory to the lamp driving circuit. Then, driving the lamp by the lamp driving circuit corresponding to the supplied lamp operating parameter In the lamp control circuit, the communication circuit comprises a memory and is configured to supply the lamp operating parameter to the lamp driving circuit, when the lamp driving circuit is supplied with a supply voltage. In an embodiment, the lamp operating parameter may be supplied to the memory when no supply voltage is supplied to the lamp control circuit.
