PROBLEM TO BE SOLVED: To sufficiently ensure brightness of a high-luminance region in a light distribution pattern formed by irradiation light from a projector type vehicular lighting tool.SOLUTION: In a first light source unit 20A and second light source units 20BL, 20BR arranged on a rear side with respect to a projection lens 12, the luminance of the first light source unit is made higher than those of the second light source units, and irradiation is performed forward from the projection lens. In the irradiation, the vicinities of the central parts of a light distribution pattern PL for low beam and a light distribution pattern PH for high beam are irradiated with high-luminance light HZL, HZH, and the high-luminance light is contained in the light distribution pattern for low beam and the light distribution pattern for high beam.SELECTED DRAWING: Figure 4 |
