1. A vehicular illuminator, comprising:
- a sensing electrode;
an electrostatic capacity detector operative to detect an electrostatic capacity between the sensing electrode and ground and provide a detection value corresponding to the electrostatic capacity;
a controller operative to input the detection value for comparison with previously determined n threshold values (n is a natural number) and provide a control value corresponding to a magnitude relation therebetween; and
a light source controllably dimmed based on the control value.

Abstract
A vehicular illuminator having a design board, behind which a sensing electrode having an aperture is located. Arranged between the design board and the sensing electrode is an LED serving as a light source and a light guide plate to defuse light from the LED. The sensing electrode is connected to an electrostatic capacity detector contained in a controller.

15. An illuminator, comprising:
-
a sensing electrode;
an electrostatic capacity detector operative to obtain a detection value, where the detection value is an electrostatic capacity between the sensing electrode and ground;
means for comparing the detection value with previously determined n threshold values (n is a natural number) and for controllably dimming a light source based on the comparison.
