VEHICULAR LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JP2019029247
Kind Code:
A
Abstract:
To provide a vehicular lighting fixture which can provide a low light intensity place at a central part of a light distribution pattern which is formed by allowing light from a light source to enter a lens directly.SOLUTION: A vehicular lighting fixture 10 includes a lens 12 for forming a light distribution pattern P by radiating light which has directly entered an incident surface 23 from a light source (11) frontward from an emission surface 24. The emission surface 24 has a condensing surface part 25 including a reference optical axis Lb of the lens 12 and a diffusion surface part 26 in the peripheral part. The condensing surface part 25 forms a condensing pattern part Pg located at the central part of the light distribution pattern P. The diffusion surface part 26 forms a diffusion pattern part Pd located in the peripheral part of the light distribution pattern P. The condensing surface part 25 is divided into a first condensing surface portion 31 for forming a right side condensing pattern part Pgr on the right side of the condensing pattern part Pg, and a second condensing surface portion 32 for forming a left side condensing pattern part Pgl on the left side of the condensing pattern part Pg.SELECTED DRAWING: Figure 4
