More Information
Summary:A light emitting device includes light emitting chips, a mount board on which the light emitting chips are mounted, and a buffer amplifier. Each of the light emitting chips includes light emitting elements and transfer elements. The transfer element sequentially specify, by sequentially entering an on-state, the light emitting elements as targets for control of illumination or non-illumination. Each of the transfer elements is provided for a corresponding one of the light emitting elements. The buffer amplifier is provided on the mount board, and outputs a transfer signal on the basis of an input transfer signal. The transfer signal is used to sequentially set the transfer elements, which are included in each of the light emitting chips, to be in the on-state.
