Abstract
A vehicle lamp includes a projection lens, a first light emitting chip and a second light emitting chip disposed on left and right sides, and a reflector which reflects light toward the projection lens. The reflector includes a reflecting surface which includes a left rear area, a right rear area, a left front area, and a right front area. The left rear area and the right front area reflect light emitted from the first light emitting chip to converge to a rear focal point of the projection lens at a higher convergence degree than light emitted from the second light emitting chip. The right rear area and the left front area reflect light emitted from the second light emitting chip to converge to the rear focal point of the projection lens at a higher convergence degree than light emitted from the first light emitting chip.
