<p>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.</p> |
