Abstract:
1. A light-emitting-diode (LED) protection circuit, comprising: a light-emitting-diode module; two fuse elements, connected respectively to said LED module, when current flowing through is greater than a current protection value, said two fuse elements are in an open circuit state, to cut off an over current and prevent it from flowing to said LED module; and a discharge protection element, connected to said LED module and said two fuse elements, said discharge protection element providing a current bypass route for said LED module; wherein said two fuse elements are a first fuse element and a second fuse element respectively, two ends of said first fuse element are connected respectively to a positive end of a DC power supply and a positive end of said LED module, two ends of said second fuse element are connected respectively to a negative end of said DC power supply and a negative end of said LED module, and two ends of said discharge protection demerit are connected respectively to said positive end and said negative end of said DC power supply.
