Light unit for use in vehicle that leans into turns and vehicle that leans into turns

摘要

A light unit for use in a vehicle that leans into turns, the light unit comprising:
a fixed part (101) fixed to a vehicle body that is allowed to lean while the vehicle is running;
a main headlight (110,120) provided in the fixed part (101) and configured to be turned on irrespective of a lean angle of the vehicle; and
a sub headlight (130) provided in the fixed part (101) and configured to be turned on in accordance with the lean angle of the vehicle while the vehicle is running,
the main headlight (110,120) including a main LED light source (111), a main cut-off line producing part (112), and a main heat sink (113,163), the main cut-off line producing part (112) being configured to produce a cut-off line at the upper side of light emitted from the main LED light source (111), the cut-off line extending in a width direction of the vehicle when the vehicle body is upright, the main heat sink (113,163) being configured to dissipate heat of the main LED light source (111), the sub headlight (130) including a sub LED light source (131), a sub cut-off line producing part (132), and a sub heat sink (113,123), the sub cut-off line producing part (132) being configured to produce a cut-off line at the upper side of light emitted from the sub LED light source (131), the cut-off line extending obliquely when the vehicle body is upright, the sub heat sink (113,123)being configured to dissipate heat of the sub LED light source (131),
the main heat sink (113,163) being provided integrally with the main cut-off line producing part (112),
the sub heat sink (113,123) being provided integrally with the sub cut-off line producing part (132),
the sub heat sink (113,123) being provided integrally with the main heat sink (113,163) such that heat conduction between the sub heat sink (113,123) and the main heat sink (113,163) is allowed,
the main cut-off line producing part (112) and the sub cut-off line producing part (132) being provided in such a manner that the main cut-off line producing part (112) and the sub cut-off line producing part (132) are allowed to move simultaneously under a state where the fixed part (101) is fixed to the vehicle body.
