More Information
Summary:The present invention relates to an energy-saving controlling method of light-emitting module, whose method is: disposing an exchange controlling circuit in the control circuit of the light-emitting module to provide a high-frequency and a low-frequency current output signal of the time-division period; dividing the unit time length t into some equal parts and separately outputting signals, with one power output circuit matching exchange controlling circuit to perform different-power outputted current; controlling current to the light-emitting module for emitting light, under the separated mode of a predetermined time length to supply normal current and another predetermined time length to supply energy-saving current, while the frequency of the light-emitting module to be supplied with normal current needs to be greater than or equal to 16 times/second.
