Latest Patents

One of Nakayama's latest patents is a planar lighting device. This device includes a light source and a light-guiding plate with a light incident end face where the light source is arranged. The plate features a facing end face and a pair of principal faces that connect the two. Additionally, it incorporates a plurality of optical elements on at least one of the principal faces, which consist of unevenly shaped parts with recesses and projections arranged intermittently from the light incident end face toward the facing end face.

Another notable patent is the spread illuminating apparatus. This invention allows light entering from an incident light surface of a light guide plate to be guided not only forward but also modified by optical elements within the plate. This design inhibits wasteful emission from the emitting surface while guiding light in a longitudinal direction. The optical elements enhance light diffusivity and control the directivity of the emitted light.
