PURPOSE: An LED test apparatus is provided to reduce manufacturing costs and unit costs and to improve reliability and accuracy. CONSTITUTION: A tray(9) forms a socket groove(9a) corresponding to a socket(10). The socket is detachably installed in the socket groove of the tray by using a fixture such as a screw and forms a plurality of insertion grooves(10a) corresponding to LEDs(1). A contact pin(20) is installed in an LED counter surface of the insertion groove and electrically contacts a contact terminal(1a) of the LED. A heat transfer member is installed in the counter surface of the insertion groove and thermally contacts the LED. A thermal dissipation plate dissipates heat generated from the LED by being thermally connected with the heat transfer member.
