Abstract
The prevent invention provides a light-emitting device for providing a flash light source comprising a light-emitting module and a control module. The light-emitting module comprises a circuit substrate and a plurality of light-emitting elements disposed on the circuit substrate and electrically connected to the circuit substrate. The control module comprises a semiconductor switch element having a MOSFET for turning the light-emitting elements on or off, wherein the semiconductor switch element is electrically connected to the light-emitting elements thereby the light-emitting elements can flash via the semiconductor switch element alternately turning on and off the light-emitting elements.
