According to example embodiments, a light emitting device (LED) module includes a substrate, a LED on the substrate, a first reflector on the substrate, and a phosphor structure contacting the first reflector. The first reflector may surround the LED from a plan view. The first reflector may have a width at a middle portion of the reflector that is smaller than a width at a bottom portion of the reflector. The LED module may obtain a desired view angle depending on various applications by adjusting a height of the first reflector and/or a difference between the height of first reflector and a height of a phosphor structure.
