Vehicle interior illumination device
First Claim
1. A vehicle interior illumination device comprising:
- a housing secured to a vehicle interior;
a light source secured to an inside of said housing;
an illumination lens disposed on a surface on the vehicle interior side of said housing, which transmits light from said light source for illuminating said vehicle interior;
an electrode disposed on the surface on the light source side of said illuminating lens; and
an illuminating power control unit which is connected to said electrode, and which switches said light source power on and off based on changes in capacitance between said electrode and a person, which are caused by said person making contact with a vehicle interior side surface of said illuminating lens.
