To provide a lighting device capable of suppressing deviations in timing of lighting a plurality of light sources.SOLUTION: A lighting device includes a first lighting circuit that lights up a first light source when a state of a first signal satisfies a first condition and changes brightness of the first light source according to the state of the first signal, a second lighting circuit that lights a second light source when a state of a second signal satisfies a second condition different from the first condition, and changes brightness of the second light source according to the state of the second signal, and a first output circuit that outputs the first signal whose state changes from a first initial state that satisfies the first condition to the first lighting circuit such that the first light source lights up and gradually becomes brighter on the basis of an instruction signal, and outputs the second signal whose state changes from a second initial state that satisfies the second condition to the second lighting circuit such that the second light source lights up and gradually becomes brighter.SELECTED DRAWING: Figure 3
【課題】複数の光源を点灯させるタイミングのズレを抑制することができる点灯装置を提供する。【解決手段】点灯装置は、第1信号の状態が第1条件を満たすと第1光源を点灯させ、前記第1信号の状態に応じて前記第1光源の明るさを変化させる第1点灯回路と、第2信号の状態が前記第1条件とは異なる第2条件を満たすと第2光源を点灯させ、前記第2信号の状態に応じて前記第2光源の明るさを変化させる第2点灯回路と、指示信号に基づいて、前記第1光源が点灯して徐々に明るくなるよう、前記第1条件を満たす第1初期状態から状態が変化する前記第1信号を前記第1点灯回路に出力するとともに、前記第2光源が点灯して徐々に明るくなるよう、前記第2条件を満たす第2初期状態から状態が変化する前記第2信号を前記第2点灯回路に出力する第1出力回路と、を備える。【選択図】図3
