摘要： PURPOSE:To facilitate motions with ocular confirmation as preparation for getting out of a car by lighting up an illumination during the period from car stop till door opening, and increasing the brightness as following the light adaptation curve of the eyes in compliance with the lightness of the surrounding. CONSTITUTION:When a car is stopped, a lighting signal for giving information about the driver, etc., getting out of the car is given from a getout signal generating part 1 to a lighting circuit 3 under the period from the car having stopped till the door being opened. An external light sensing part 2 senses from the lightness of the surrounding whether an illumination 6 must be lighted up. In conformity to these sensing signal and lighting signal, the lighting circuit part 3 put a power supply 5 in connection with a lighting time control part 4, and thus the illumination 6 is lighted up. This lighting time control part 4 increases the brightness of the illumination 6 as following the light adaptation curve of the eyes. This allows informing a co-passenger or passengers early about getting out with easier motions with ocular confirmation as preparation for getting out, eliminates the discomfort due to getting light suddenly, and also prevents drop of the sight.

摘要： PURPOSE:To allow to begin alighting preparation on this side of an alighting position by transmitting a first signal for optionally lighting seat lamps, and then sending a second signal for lighting foot lamps and arm rest lamps concurrent with or after the lighting of the seat lamps. CONSTITUTION:The transfer of a first signal, for lighting seat lamps 3, to a lighting circuit part 13 from an alighting signal transmitting part 11 in order to inform alighting by a driver 16, causes the actuation of the lighting circuit part 13 to light the seat lamps 3. This brightly illuminates at least the seat surfaces 15 of a rear seat 4 and front seats 17, previously informs alighting to a fellow passenger 18, eases to see and quickens viewing work for alighting preparation, and permits alighting with composure. Then a second signal, for lighting foot lamps 6 and arm rest lamps 10, is automatically transmitted from the alighting signal transmitting part 11 concurrent with or after the lighting of the seat lamps 3 to also light the foot lamps 6 and the arm rest lamps 10.

摘要： PURPOSE:To quickly confirm the safety of a road surface and a step part and give an guiding effect to an alighting direction at the time of alighting by controlling illumination with an operation circuit so that the floor surface brightness can be lighter than the seat surface brightness in the vicinity of a door, and the brightness of a road surface and a step part can be lighter than the floor surface brightness when the door is opened. CONSTITUTION:Receiving the opening signal of a rear door 15, a road surface 20 in the vicinity of the opened rear door 15 and a step part 21 is illuminated with a step lamp 3, a floor surface 19 in the vicinity of the opened rear door 15 is illuminated with a foot lamp 2, and the surface 18 of the seat cushion 14 of a rear seat 13 in the vicinity of the opened rear door 15 is illuminated with a seat lamp 1. These illumination methods bring higher brightness to the floor surface 19 than to the surface 18 of the seat cushion 14 of the rear seat 13, and higher brightness to the road surface 20 and the step part 21 than to the floor surface 19. Such setting of brightness is intended to draw the eyes of the riders more to the road surface 20 and the step part 21 by sufficiently lightening the road surface 20 and the step part 21 which are viewing objects.

摘要： PURPOSE:To enhance the passenger leading effect by lighting up a step light, foot light, and seat light when the door is opened, and controlling them so that the floor brightness is higher than the road surface brightness and that the seat surface brightness is higher than the floor surface brightness. CONSTITUTION:When a door 39 is opened, a light puton/putoff circuit lights up a step light 1, foot light 2, and seat light 3. No.1 sensor 4 senses the brightness of the road surface 31, No.2 sensor 5 the brightness of the floor surface, and No.3 sensor 6 the brightness of the seat 33 surface, and on the basis of the signals thus obtained a calculation circuit controls the illuminations of the lights 1-3 so that the floor surface brightness is higher than the road surface 31 brightness and that the seat 33 brightness is higher than the floor surface brightness. This enhances the passenger leading effect and achieves the intra- coupe illumination which provides a sense of center.
