摘要： A light emitting module device includes: a power line through which power is supplied to light emitting modules; and a signal generation circuit which generates a control signal. The power line is shared by a plurality of the light emitting modules, and has switches and switches which turn on or off current conduction to the light emitting modules, through open/close operations. The signal generation circuit individually controls the switches and the switches. The open/close operations include a light-emission period in which the light emitting module emits light; and an extinction period in which the light emitting module is extinguished, and if there is a control signal to be transmitted to the light emitting module, the control signal is superimposed onto supply power. Since a control signal is superimposed onto supply power to each light emitting module, the light emitting modules can be individually controlled. In addition, since the power line can be used also as a communication line, and the power line can be shared by a plurality of the light emitting modules, the number of lines can be decreased.
