Title:
LIGHT SOURCE MODULE
Document Type and Number:
WIPO Patent Application WO/2023/189244
Kind Code:
A1
Abstract:
This light source module comprises: a first light-emitting part; a light guide member; a light reflection member; a light branch member; and a retroreflection member. The light guide member has a linear part and a bent part. The linear part and the bent part have a first surface for outputting light emitted from the first light-emitting part in a first direction and a second surface positioned on a side opposite to the first surface. The linear part extends in a second direction orthogonal to the first direction, and the bent part bends from the second direction toward the first direction. In the linear part and the bent part, the light reflection member is disposed closer to the second surface than to the first surface. The light branch member has a third surface, and the retroreflection member has a fourth surface. The third surface reflects a portion of the light outputted from the first surface to the fourth surface.
