LIGHT LENS FOR CAR INTERIOR LIGHTING DEVICE
First Claim
1. A light lens used for a car interior lighting device for transmitting light from a light source therethrough and illuminating the car interior, the light lens comprising:
- a transparent light lens body;
a colored transparent conductive coating film located on a light source side of the light lens body, for detecting capacitance; and
an insulative coating film that has almost the same color and transmission rate as the conductive coating film and is located on a periphery of the conductive coating film.

Abstract
A light lens used for a car interior lighting device for transmitting light from a light source therethrough and illuminating the car interior is provided, and the light lens has a transparent light lens body, electrodes that are colored transparent conductive coating films for detecting the capacitance and located on a light source side of the light lens, and an insulative coating film that has almost the same color and transmission rate as the conductive coating films and is located on the periphery of the conductive coating films. With this configuration, the uniform light transmission rate is achieved over the light lens.
