<P>PROBLEM TO BE SOLVED: To provide a lighting device for a cabin having a switch with sufficient visibility, a long life and stable action. <P>SOLUTION: The lighting device 1 for the cabin is provided with a box body 3 fixed to the cabin; a light source 16 fixed to the inside of the box body 3; and a lighting lens 10 arranged on the in-cabin side surface of the box body 3. In the lighting device 1, light from the light source 16 is permeated through the lighting lens 10 and illuminates the inside of the cabin. The lighting device 1 has electrode parts 14, 15 formed on the side surface of the light source of the lighting lens 10 in a thin film-like shape; a lighting power source control part connected to the electrode parts 14, 15 and performing the turning-on/off of the power source of the light source 16 based on the variation of an electrostatic capacity between the electrodes 14, 15 and a human body caused by the fact that the human body is contacted with the cabin inner surface of the lighting lens 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
