Title:
VEHICULAR LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JP2018045879
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture capable of effectively suppressing dew formation to an internal surface of a transparent cover, wherein a lamp chamber is formed by a lamp body and the transparent cover.SOLUTION: A vent hole 14Ca for causing spaces inside/outside a lamp chamber 16 is formed at two places of a transparent cover 14, and then, a filter 40 having waterproofness and moisture diffusivity is attached so as to close each vent hole 14Ca. When a vehicular lighting fixture 10 is incorporated with a vehicle body 2, the transparent cover 14 is located at a position having comparatively low humidity, separated from a part of an engine room 4 which becomes high humidity. Then, it is easy to discharge moisture generated inside the lamp chamber 16 by a diffusion action by providing the transparent 14 with a ventilation structure.SELECTED DRAWING: Figure 2
