发明名称 LIGHTING DEVICE AND DISPLAY DEVICE
摘要 A lighting device includes a translucent member having the same cross sectional tubular shape throughout a longitudinal direction and including a lens that includes a light incident surface for receiving incident light and a pair of light exit surface for diffusing and emitting the light incident on the light incident surface to the outside, and a light-emitting portion mounted on a substrate and emitting the light toward a region including the light incident surface of the translucent member, where in the translucent member includes a pair of light guide portions for guiding the light incident on the light incident surface to a pair of the light exit surfaces so that the light incident on the light incident surface is diffused and emitted from the pair of light exit surfaces in a width direction that is orthogonal to the longitudinal direction.

主权项 1. A lighting device, comprising: a translucent member having a same cross sectional tubular shape throughout a longitudinal direction and comprising a lens that comprises a light incident surface for receiving an incident light and a pair of light exit surfaces for diffusing and emitting the incident light onto the light incident surface to an outside; a substrate arranged inside the translucent member along the longitudinal direction; and a light-emitting portion mounted on the substrate and emitting the light toward a region including the light incident surface of the translucent member, wherein the light incident surface of the translucent member is provided facing the light-emitting portion, and wherein the lens of the translucent member comprises a pair of light guide portions for guiding the incident light onto the light incident surface to a pair of the light exit surfaces such that the incident light onto the light incident surface is diffused and emitted from the pair of light exit surfaces in a width direction that is orthogonal to the longitudinal direction.
