Document Type and Number:
WIPO Patent Application WO/2012/023602
Kind Code:
A1
Abstract:
[Problem] To provide a vehicle lighting fixture such that a different light emitting design for each vehicle owner can be easily configured. [Solution] This vehicle lighting fixture (1) is configured with: a point light source (6); a substrate (7); a cylindrical frame (2); a bottom-surface reflection part (5); a side-surface reflection part (4); a light-guide reflection plate (3); and a translucent cover (8). The bottom-surface reflection part (5), the side-surface reflection part (4), and the light-guide reflection plate (3) are arranged in the frame (2). The surface of the bottom-surface reflection part (5) facing the light-guide reflection plate (3), the inner surface of the side-surface reflection part (4), and the surface of the light-guide reflection plate (3) facing the bottom-surface reflection part (5) are formed by members having high light reflectance and low light transmittance. The frame (2) has a bent portion for engagement (2c) at one end portion of the opening thereof and the side-surface reflection part (4) arranged on the inner surface side thereof. The light-guide reflection plate (3) has holes (3b1) and narrow grooves (3a3) formed thereon so as to obtain a desired light emitting pattern and is held and sandwiched between the bent portion for engagement (2c) of the frame (2) and the side-surface reflection part (4). The side-surface reflection part (4) is held by the end portion at the other side of the frame (2) and the bottom-surface reflection part (5) fixed to the substrate (7).
