Document Type and Number:
Japanese Patent JP6056614
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve a problem in a conventional vehicle lamp that the light free from light distribution control, may be emitted upward to the external from an additional lens.SOLUTION: A vehicle lamp includes a lens 2 and a semiconductor-type light source 3. The lens 2 is composed of a main lens portion 6, and an auxiliary lens portion 7. The auxiliary lens portion 7 is composed of an incident surface 70, a reflection surface 71, an emission surface 72 and a first connection surface 81. The first connection surface 81 is formed at a draft angle of a mold to emit the light L1 from the semiconductor-type light source 3, that is, the incident light L5 entering into the auxiliary lens portion 7 from the first connection surface 81, downward to the external as the downward emission light L6 from the emission surface 72. As a result, the emission light L6 free from light distribution control, can be emitted downward.
