Abstract
The present disclosure provides a light-emitting device having an ambient light sensing function, including a light-emitting module, a rectification module, a switch module, a control module, and an ambient light sensing module. The light-emitting module includes a circuit substrate and a plurality of light-emitting elements. The rectification module is electrically connected to the light-emitting module. The switch module includes a semiconductor switch element electrically connected to the light-emitting module. The control module is electrically connected to the rectification module and the switch module. The ambient light sensing module is electrically connected to the control module for receiving an ambient light source. The ambient light sensing module provides a light intensity signal to the control module according to a light intensity provided by the ambient light source, and the light-emitting elements are turned on or turned off by the semiconductor switch element according to the light intensity signal.
