  • Power efficient driving circuits of light source for projectors
    Patent number: 9013112
    Abstract: A system for driving current to the light source may include a first inductor to supply current to the light source, a power source to supply current to the inductor, a first switch SET to supply current to the inductor without supplying the current to the light source and a second switch SET to supply the current from the inductor to the light source. Also a system for driving current to light source may include two inductors or a transformer, to supply current to the light source by connecting the first inductor to the light source by a switch set, while the second inductor may be connected to the voltage source by another switch set. And this role can be exchanged between the two inductor alternately and in sequence, defined by time periods.
