Since the rising current supplied to the luminaire is gradually increased at the lighting start stage, the brightness of the luminaire is gradually increased, and when a person steps into the lighting control area, the luminaire does not suddenly turn on with high brightness. It does not surprise people.
Further, (2) since the falling current supplied to the lighting fixture is gradually reduced at the lighting termination stage, the brightness of the lighting fixture is gradually reduced so that the person in the lighting control area recognizes that the turning-off timing is approaching. However, it can be turned off.
