Abstract:
1. An optical assembly, comprising: a first layer; a plurality of light sources disposed over the first layer; a second layer that is disposed above the first layer and covering the plurality of light sources; at least one reflection layer between the first layer and the second layer; and a plurality of reflection patterns, wherein each of the plurality of reflection patterns is formed at a position on the second layer corresponding to a respective one of the plurality of light sources, wherein the first layer is a substrate on which the plurality of light sources are mounted, wherein the second layer is on an upper side of the plurality of light sources and on a lateral side of the plurality of light sources between the plurality of light sources to encapsulate the plurality of light sources, wherein the second layer is directly connected to the upper side and the lateral side of each of the plurality of light sources, wherein each of the plurality of reflection patterns is formed by printing the second layer with a plurality of dots, wherein a density of the plurality of dots gradually decreases from a center of each reflection pattern to an outer area, wherein each of the plurality of reflection patterns is an embossed pattern, and wherein each of the plurality of reflection patterns has a shape off-centered from an area corresponding to the respective one of the plurality of light sources.
