  • System and device for driving a plurality of high powered LED units
    Patent number: 9408273
    Abstract: A system for driving a plurality of high powered LED units, the system comprising a single driver for providing ripple free constant direct current to a plurality of high powered LED lamp units, wherein the single driver comprises a digital controller programmable to adjust the ripple free constant direct current at every predetermined time interval based on detection and computation of the duration taken for the energy to be discharged to the LED lamp unit to adjust the ripple free constant direct current. The above system achieves a one driver to many LED lamp units such that it alleviates or eliminates the need to have a driver attached to each LED lamp unit.
