A light-emitting-diode (LED) protection circuit, comprising: a light-emitting-diode module; two fuse elements, connected respectively to said LED module; and a discharge protection element, connected to said LED module and said two fuse elements. When current flowing through said fuse element exceeds a current protection value, said fuse element will turn into an open circuit state, to cut off an over current and prevent it from flowing to said LED module to avoid damages. In addition, when instantaneous high voltage occurs, such as incurred by a spike or a lightning, said discharge protection element can be used as an over current discharge route, to provide said LED module with a current bypass route. |
