Patent ID: 8066418

Claim:
A lighting device comprising: three or more light-transmitting guide bodies arranged in parallel to each other; a plurality of light emitting elements opposed to respective one ends of the light-transmitting guide bodies to thereby emit light fluxes in different colors to the light-transmitting guide bodies respectively; a plurality of reflecting surfaces formed in each of the light-transmitting guide bodies to change a propagation direction of the light flux propagated in the each light-transmitting guide body, thereby emitting the light flux from a lateral surface of the each light-transmitting guide body; and a light-transmitting guide plate assembly arranged beside the light-transmitting guide bodies so as to allow the light fluxes emitted therefrom to be incident on a lateral side of the light-transmitting guide plate assembly and further emit the light fluxes from a front side thereof, the light-transmitting guide plate assembly having a plurality of light-transmitting guide plate juxtaposed to each other, wherein the reflecting surfaces are formed in the each light-transmitting guide body so that the light flux emitted from one light-transmitting guide body is incident on the lateral side of the light-transmitting guide plate assembly through the other light-transmitting guide body's part where the reflecting surfaces are not formed.
