LENS AND EMBEDDED MARKER LAMP

摘要

PROBLEM TO BE SOLVED: To provided an embedded marker lamp with a lens 38 that can obtain required light distribution characteristics and an improved light emitting efficiency.

SOLUTION: A main lens portion 62 of the lens 38 forms a main light distribution where light incident from a light emitting diode 36 is emitted to a central region of an optical axial direction b. A sub-lens 63 of the lens 38 forms a sub light distribution where the light incident from the light emitting diode 36 is emitted to right and left regions of the main light distribution. Auxiliary lens portions 64, 65 of the lens 38 forms an auxiliary light distribution where the light incident from the light emitting diode 36 is emitted to a region lapping over the main light distribution and the sub light distribution. The lens 38 can obtain required light distribution characteristics of an oblong form suitable for an embedded marker lamp and an improved light emitting efficiency.
