发明名称 LIGHTING DEVICE AND METHOD OF MANUFACTURING THE SAME
摘要 Disclosed are a lighting device and a method of manufacturing the same, the lighting device includes a diffusion layer diffusing and emitting light incident from a light source; a bead layer adjacently formed to a light emitting surface of the diffusion layer, including a plurality of beads, and having a separation part formed in a region in which the plurality of beads are not present; and a condensing layer formed on the bead layer and condensing light transmitting the separation part to a predetermined portion. The exemplary embodiment of the present invention can form the separation part on the diffusion layer and the condensing layer by bonding beads to the diffusion layer and thus, can condense the light transmitting the diffusion layer to the condensing layer through the separation part, thereby easily reducing the UGR without disposing the separate barrier rib structure between the diffusion layer and the condensing layer.
