To provide good-response lighting control with simple constitution.SOLUTION: A lighting control device 1 for a light source unit 2 that includes at least a first light source module 21 which has a relatively small electric load and a second light source module 22 which has a relatively large electric load, executes, when a voltage supply circuit supplies voltages to each of the first light source module and second light source module, a first control of turning the voltage supply circuit ON to supply the voltage to the first light source module, a second control of disconnecting a current path of the first light source module and keeping the voltage supply circuit ON, and a third control of connecting a current path of the second light source module and keeping the voltage supply circuit ON.SELECTED DRAWING: Figure 1

    【課題】簡素な構成で応答性のよい点灯制御を提供する。【解決手段】相対的に電気的負荷の小さい第1光源モジュール21と相対的に電気的負荷の大きい第2光源モジュール22とを少なくとも含む光源ユニット2の点灯制御装置1であって、第1光源モジュールと第2光源モジュールの各々に対して電圧供給回路により電圧を供給する際に、電圧供給回路をオン状態にして第1光源モジュールに電圧を供給させる第1制御と、第1光源モジュールの電流経路を遮断し、かつ、電圧供給回路をオン状態で維持する第2制御と、第2光源モジュールの電流経路を導通させるとともに電圧供給回路をオン状態で維持する第3制御と、を実行する。【選択図】図1
