Title:
The light implement for vehicles
Document Type and Number:
Japanese Patent JP6131571
Kind Code:
B2
Abstract:
[Problem] In conventional vehicle lamp devices, exit light exits from stepped partition surfaces without having been subjected to light distribution control. [Solution] The present invention is provided with a lens, and a semiconductor-type light source. The lens is configured from one incidence surface, and nine exit surfaces partitioned by stepped partition surfaces. Among the nine exit surfaces, lower exit surfaces are positioned further towards a side in the exiting direction of light than upper exit surfaces. As a result, in the present invention, exit light exiting from horizontal stepped partition surfaces is subjected to light distribution control by the horizontal stepped partition surfaces which are downwardly inclined from above, is refracted downwards to the optical axis of the lens, and exits.
