Abstract: The present embodiment comprises: a plurality of light-emitting units; and a reflector including reflector units having spaces formed to receive the plurality of light-emitting units, respectively. Each of the plurality of light-emitting units includes an LED package mounted on a substrate and a light diffusion layer having a groove portion formed on a surface opposite to the substrate in the LED package, wherein the outer circumference of the light diffusion layer faces the inner surface of a reflector unit. In the reflector, the plurality of reflector units are integrally formed, the spaces expand along a direction extending away from the substrate, and a wall forming each of the spaces surrounds the outer circumference of each of the LED package and the light diffusion layer.
