A lighting device comprising a reflective layer provided on a part of each lenticular lens surface. (2) In the lenticular lens sheet, the optical axes of the lenticular lens on the light output side and the lenticular lens on the light source side are substantially aligned, and the light is emitted inward from the focal position of the lenticular lens on the light source side. The lighting device according to claim 1, characterized in that there is a surface of a lenticular lens on the side. (3) The reflective layer is provided at and in the vicinity of a light output portion of the light output side lenticular lens when parallel light from a vertical direction is incident on the light source side lenticular lens. A lighting device according to claim 1 of the utility model registration claim. (4) The lighting device according to claim 1, wherein the light source is one or more point light sources or rod-shaped light sources. (5) A request for registration of a utility model characterized in that the lenticular lens sheet is used in combination with a light-condensing linear Fresnel lens between the light source and whose optical axis is at a position opposite to the light source position. The lighting device according to item 1. (6) The lighting device according to claim 1, wherein the lenticular lens sheet is used in combination with an isotropic light diffusing plate disposed on the outside.
