Abstract:
A small and thin lighting device with high efficiency and good design and a headlight for a vehicle. A lighting device includes a first lens taking light generated by a light emitting device and emitting the light, and a second lens taking an emitted light from the first lens and emitting the light, in which the second lens is an anamorphic lens in which curvatures are different in a vertical direction and a right and left direction and a center of a lens surface in the vertical direction of the second lens is positioned in an upper direction with respect to an optical axis of the first lens. A headlight for a vehicle including the plural lighting devices is forming a low beam light distribution by superimposing lights from respective lighting devices for irradiation of the center, right and left in a horizontal direction respectively.

Claim (Index 1):
A lighting device comprising:\n a light emitting device; a first lens taking light generated by the light emitting device and emitting the light; and a second lens taking an emitted light from the first lens and emitting the light in a given direction, wherein the first lens includes an incident port on which light generated by the light emitting device is incident, an emission port from which light incident on the incident port and passing through the inside of the first lens is emitted, and a side surface portion including a plurality of side wall surfaces provided between the incident port and the emission port, the incident port of the first lens has a concave shape surrounding the light emitting device, having a first incident surface as a concave bottom surface and a second incident surface as a concave side surface, the side surface portion includes a first reflective surface on which light incident on the second incident surface is reflected and a second reflective surface on which light incident on the first incident surface and light reflected on the first reflective surface are reflected, and the second lens is an anamorphic lens in which curvatures are different in a vertical direction and a right and left direction, and includes a light incident part in the vertical direction formed in a convex shape and a light emission part, wherein the light incident part or the light emission part in the right and left direction is formed in a convex shape, a concave shape or a linear shape.
