Kind Code:

A1

Abstract:

In order to provide a vehicle lamp that can be reduced in size and that has a configuration capable of being made compact, which is for forming a diffused light pattern, this vehicle lamp is provided with: a semi-conductor-type light source; a second lens having an incident surface in which two convex sections protruding toward the light source side on the outer side in the horizontal direction from the center are connected at the center side to form a portion on the center side which is recessed on the inner side; and a first lens that is disposed between the light source and the second lens and irradiates the second lens with the light from the light source such that a spread of light from the light source is converted to a spread entering the incident surface of the second lens and a diffused light distribution pattern irradiated on the vehicle front side spreads outward in the vehicle horizontal direction. The portion that recesses on the incident surface of the second lens is formed into a surface shape to control light distribution so as to form almost the entirety of the diffused light distribution pattern, and an outer portion of the incident surface of the second lens in the horizontal direction is formed into a surface shape to control light distribution so as to form a high light intensity band on the center side of the diffused light distribution pattern in the horizontal direction.
