Interior illumination lamp
View Patent ↗A design part 20 is attached to an aperture 12 provided in an interior material 11 of a automobile, and a functional part 30 is arranged at the rear side of the interior material 11 supported by the design part 20 . A switching unit 32 feeding and cutting an electric power to a light source 31 is configured as a separate body attached to a functional main body 30 a in such a manner that switch units 32 of different mechanisms can be selectively attached to the functional main body 30 a . Thus, since the functional main body 30 a is used in common even when the switching unit 32 is changed and has a general-purpose nature, cost reduction can be attained.
1. An interior illumination lamp comprising:
a design part having a lens fixed to a housing attachable to an aperture provided in an interior material of a automobile;
a functional part including a functional main body having a light source connected thereto, said functional main body being supported by the design part at the rear side of the interior material; and
a switching unit alternatively feeding and cutting electric power to the light source, and provided in the functional main body of the functional part, the switching unit being removably provided on the functional main body.
2. The interior illumination lamp set forth in claim 1 , wherein the functional main body includes:
an accommodation unit capable of accommodating the switching unit;
