<p>PROBLEM TO BE SOLVED: To provide a vehicle interior lighting device that can save a space by reducing the number of part items, can perform lighting as if light flows, and can enhance a performance effect.SOLUTION: A vehicle interior lighting device 1 includes: a light guide 3; a first light source (first light emitting diode 4) arranged at the one-end side of the light guide; a second light source (second light emitting diode 5) which is arranged at the other end side of the light guide, and emits a color different from that of the first light source; a control part 6 which controls lighting of the first and second light sources so that a light emitting quantity of the second light source may be reduced while increasing a light emitting quantity of the first light source; and a first irradiation part 7 for irradiating a vehicle interior with the light of the light guide. The first irradiation part has a first wall 12 irradiated with the light of the light guide, and a second wall 13 irradiated with light reflected on the first wall.</p> |
