Abstract
A light-emitting device includes multiple transfer elements, multiple setting elements, multiple light-emitting elements, and a controller. The transfer elements sequentially enter an on state. The setting elements are connected to the transfer elements. In response to the transfer elements entering the on state, the setting elements are allowed to enter an on state. Each of the light-emitting elements is connected to a corresponding one of the setting elements. In response to each of the setting elements entering the on state, the corresponding one of the light-emitting elements enters an on state to emit light or increase a light emission intensity thereof. The light-emitting elements are maintained in the on state in parallel. The controller controls the setting elements to enter the on state in accordance with a received illumination control signal, and controls an illumination period of the light-emitting elements.
