Title:
VEHICULAR INTERIOR LIGHTING DEVICE
Document Type and Number:
Japanese Patent JP2023153522
Kind Code:
A
Abstract:
To provide a vehicular interior lighting device which improves a degree of freedom in design.SOLUTION: A vehicular interior lighting device 1 includes: a light source 20; a bus bar 14 which has a plate-like electrode section 14a; a lens 13 which has a light transmission section 13a and a holding structure section 13b; conductive films 30 which are formed in a part of the lens 13; and a control section 22 which switches on/off of the light source 20 according to a change of electrostatic capacitance between a finger tip F touching a light irradiation surface 13c and the electrode section 14a. The holding structure section 13b has a first side wall section 13f as a wall section with which a second main plane 14d of the electrode 14a is brought into contact and is positioned outside a light receiving surface 13d in an irradiation direction view of light. The conductive films 30 are formed on the light receiving surface 13d and a first outer wall surface 13h on an opposite side of a first inner wall surface 13i as a surface with which the second main plane 14d of the electrode section 14a is brought into contact in the first side wall section 13f. The conductive film 30 formed on the light receiving surface 13d and the conductive film 30 formed on the first outer wall surface 13h are continued to each other.SELECTED DRAWING: Figure 6
