Title:
VEHICULAR LIGHTING TOOL
Document Type and Number:
Japanese Patent JP2020061231
Kind Code:
A
Abstract:
To sufficiently ensure the brightness of a light distribution pattern even in a structure in which a light distribution pattern having a cut-off line is formed, in a vehicular lighting tool equipped with a micro lens array.SOLUTION: Light shielding plates 50 are disposed between rear side lens arrays 42A, 42B, and 42C and front side lens arrays 44A, 44B, and 44C configuring a micro lens array, and thereby, a low beam light distribution pattern having a cut-off line in an upper part can be formed. Then, as the rear side lens arrays 42A to 42C, optical axes Axa2, Axb2, and Axc2 of condenser lens portions 42As to 42Cs are offset upward with respect to optical axes Axa4, Axb4, and Axc4 of projection lens portions 44As, 44Bs, and 44Cs corresponding thereto. Therefore, a ratio of light shielded by the light shielding plate 50 of emission light from a light source unit 30 which is incident to the rear side lens arrays 42A to 42C is decreased.SELECTED DRAWING: Figure 5
