    • 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.
    • 公开了一种照明装置及其制造方法,该照明装置包括漫射并发射从光源入射的光的漫射层; 与扩散层的发光面相邻形成的珠粒层,包括多个珠粒,并且在不存在多个珠粒的区域中形成有分离部分; 以及形成在所述珠粒层上并且将透射所述分离部分的光聚光到预定部分的聚光层。 本发明的示例性实施例可以通过将珠粘合到扩散层而在扩散层和聚光层上形成分离部分,从而可以通过分离部分将透射扩散层的光冷凝到聚光层,从而容易地减少 UGR,而不在扩散层和聚光层之间设置单独的阻挡肋结构。
