Document Type and Number:
Japanese Patent JP2023169640
Kind Code:
A
Abstract:
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
