Abstract: A light-emitting device and a control method are provided. The light-emitting device is applied to a memory module. The light-emitting device includes at least one memory module board, at least one light-emitting board and an application program unit. The at least one memory module board is connected with a host. Each light-emitting board includes plural light-emitting units and a control unit. The control unit controls a lighting mode of the plural light-emitting units. The control unit is electrically connected with the host through the corresponding memory module board. The application program unit generates a control signal. The control signal is transmitted to the control unit of each light-emitting board through the host. The control unit controls the corresponding light-emitting units according to the control signal.
