DIFFUSION STRUCTURE OF LIGHT

PURPOSE: A light diffusion structure is provided to prevent a disadvantage due to point light source property by refracting light emitted from an LED device at several times. CONSTITUTION: A light diffusion structure(100) comprises a plurality of convex lenses(110) formed on a base substrate, a first housing(120), a second housing(130), and a diffusion member(140). The plurality of convex lenses is formed into a semispherical shape and formed on the rear side of a surface facing a point light source. The first housing has an arch type cross section and is formed into a tunnel shape. The first housing cover the plurality of convex lenses while be separated from the plurality of convex lenses on the base substrate. The second housing has the arch type cross section and is formed into the tunnel shape. The second housing covers the first housing. The diffusing element is formed along a longitudinal axis of the second housing within the second housing and forms a semicircular cross section.
