Abstract
System and method for driving solid-state light sources utilizing saturation mode current drivers. A preferred embodiment comprises charging a first drive circuit, discharging the first drive circuit into the solid-state light source, charging a second drive circuit, and discharging the second drive circuit into the solid-state light source. The alternating of the charging and discharging of two drive circuits ensures that there is a minimum amount of time without the capability of providing the drive current to solid-state light source. The use of saturation mode drive circuits ensures that it is possible to rapidly switch the solid-state light source on and off, improving the performance of the solid-state light source by minimizing the minimum amount of light producible by the solid-state light source, while reducing power consumption by eliminating the need to provide a headroom voltage.
