PURPOSE: A device for evaluating the reliability of a light emitting diode is provided to reduce errors of characteristic data of the light emitting diode and to prevent the characteristic transformation of a light receiving module. CONSTITUTION: A chamber (200) heats or cools a light emitting diode for measuring a temperature characteristic of a light emitting diode. A measurement unit (300) is included in the outside of the chamber and measures an optical or electrical characteristic of the light emitting diode. A stage (400) moves the light emitting diode from the measurement unit to a chamber or from the chamber to the measurement unit. A power supply unit (500) supplies power to the light emitting diode. A data storage unit (600) stores optical or electrical data measured in the measurement unit. A control unit (700) controls the chamber, the measurement unit, the stage, or the power supply unit and stores the optical or electrical data in the data storage unit.
