Due to this, optical loss may be reduced. In addition, the convex lens 301 increases the uniformity of light through internal reflection, thereby improving the uniformity of light emitted to the outside. In addition, specular reflection or internal reflection may reduce light loss, thereby reducing energy consumption. For this reason, it is possible to secure a sufficient amount of light even with a single number instead of a plurality of LED lights 211 .
