Protection architecture for multi-lamp system










Image Number 5 for United States Patent #7746006.

The present invention discloses a protection architecture for a multi-lamp system, which applies to a multi-lamp driving system for driving a plurality of lamp loops. The present invention is characterized in that two opposite-phase loads of a loop are separately defined to be a first load and a second load, and that a voltage-division/detection loop is formed via cascading a first voltage-division element to a second voltage-division element and is coupled to between the first load and the second load to detect an abnormal current, wherein the second voltage-division element is coupled to a ground terminal, and wherein a signal-acquiring terminal is coupled to between the first voltage-division element and the second voltage-division element and acquires an abnormal voltage signal for a protection unit from the abnormal current, and wherein the protection unit detects the abnormal voltage signal and shuts off the driving system.
