Disclosed herein is a quantum dot phosphor for light emitting diodes, which includes quantum dots and a solid substrate on which the quantum dots are supported. Also, a method of preparing the quantum dot phosphor is provided. Since the quantum dot phosphor of the current invention is composed of the quantum dots supported on the solid substrate, the quantum dots do not aggregate when dispensing a paste obtained by mixing the quantum dots with a paste resin for use in packaging of a light emitting diode. Thereby, a light emitting diode able to maintain excellent light emitting efficiency can be manufactured.

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.
