PURPOSE: A device for sensing the temperature of a light emitting module is provided to accurately measure the ambient temperature of the light emitting module, thereby improving the accuracy of total luminous flux measurement data. CONSTITUTION: A device for sensing the temperature of a light emitting module comprises a light emitting module(11) and a temperature measuring jig(50). The light emitting module includes a substrate(21) and a plurality of light emitting diodes formed on the substrate. The temperature measuring jig is joined to the light emitting module. The temperature measuring jig includes a body unit(51), a sensor supporting unit(61), a first fixing unit(71), a first temperature sensor(81), and a second temperature sensor(83). The body unit is fixed to the substrate. The sensor supporting unit is joined to the upper part of the body unit. The first fixing unit joins the sensor supporting unit to the body unit. The first temperature sensor is joined to the sensor supporting unit, thereby being spaced from the substrate. The second temperature sensor is joined to the sensor supporting unit, thereby being arranged towards the substrate closer than the first temperature sensor.
