Patent ID: 10502381

Abstract:
A light-emitting module includes a light source unit including light-emitting elements horizontally aligned; a projection lens receiving light emitted from the light source unit, and projecting the light through a light exiting surface of the projection lens in a radiation direction; and a frame body holding the light source unit and the projection lens at predetermined positions. The projection lens comprise a first and second lenses each having the same focal length and curvature, and being disposed adjacently in a vertical direction or as an integrated body. A vertical division ratio of lower one of the first and second lenses to the other one is larger than 1. Optical axes of the first and second lenses differ in the vertical direction. A value in the vertical direction of a horizontal-to-vertical ratio for a light-emitting area of light-emitting elements is smaller than a value in the horizontal direction of a horizontal-to-vertical ratio for the light projected from the projection lens.
