A current driver circuit comprises circuitry having a current adjustment function and operably coupled to a current driver for providing a current to a current consuming device. The circuitry comprises or is operably coupled to a function arranged to determine a current level being drawn by the current consuming device. The current adjustment function varies an over-load limit applied to the current driver in response to a variation in the determined current level. In this manner, the current level being drawn by a current consuming device, such as a light bulb, is used to continuously or intermittently adjusting the current limit of a current driver circuit, such as a lamp driver, to minimize the energy dissipated in case of an overload condition. |
