Abstract

See full text

A lighting device having resettable over-current protection function includes a light source module, a power supplying module, a DC-to-DC converting module, an over-current short-circuit protection module, a reference voltage generating module and a self-locking protection module. The power supplying module generates an input voltage. The DC-to-DC converting module converts the input voltage into a driving voltage to drive the light source module. The over-current short-circuit protection module generates a voltage detecting by detecting a driving current passing through the light source module. The reference voltage generating module generates a reference voltage according to the input voltage and the voltage detecting signal. The self-locking protection module generates a control signal according to the input voltage and the reference voltage to turn off the over-current short-circuit protection module in order to perform a self-locking protection mode, such that the DC-to-DC converting module is disconnected from the light source module.
