PURPOSE: A LED element testing system is provided to classify products into faulty products and normal products by successively performing an electronic test one by one in the state a plurality of LED elements is heated at a proper temperature by simultaneously supplying. CONSTITUTION: A LED element testing system comprises a system body(100), a frame transferring device(300), a heating and testing device(500), and a faulty product processing device(600). A transferring guide(130) is installed in the system body. The transferring guide guides a movement of a strip frame in which a plurality of LED elements is mounted in a state of a strip. The frame transferring device moves the strip frame along the transferring guide through a on-loader in one side of the system body. The heating and testing device tests the LED elements on the strip frame transferred by the frame transferring device while heating. The faulty product processing device marks the LED elements classified as the faulty products by the heating and testing device or separates from the strip frame. |
