PROBLEM TO BE SOLVED: To provide an LED light source unit provided with a light guide body capable of switching luminous colors and/or light distribution patterns in a case of line light emission using the light guide body.SOLUTION: An LED light source unit according to the present invention includes: a rod-like first light guide body (21) internally reflecting light from an LED light source provided in an end portion; and a plate-like second light guide body (31) provided opposed to the first light guide body (21). The second light guide body (31) emits light incident in the light guide body (31) from another light source to a side surface of the first light guide body (21). The light emitted from the second light guide body (31) is incident on the first light guide body (21) from an incident reflection surface (21b) of the first light guide body (21) and emitted from a first light guide body emission surface (light emission surface 11). Therefore, it is possible to emit light from the two difference light sources from the light emission surface 11. That is, it is possible to emit light having different luminous colors and having different light distribution patterns from the same light guide rod. |
