1. A mass-production LED test device comprising:

  • a control module including a central processing unit with a programmable logic controller, and a signal interface unit electrically connected to the central processing unit;

    at least one integrating sphere module electrically connected to the signal interface unit of the control module, and the integrating sphere module having an electrical output entrance, an optical output entrance and an optical input entrance; and

    at least one test board corresponding to the integrating sphere module, and the test board having a plurality of pads to which a plurality of LEDs are electrically connected, respectively, for supplying required input and output of current of each LED;

    wherein the optical input entrance of the integrating sphere module defines a predetermined measure for containing a predetermine amount of the LEDs at one time;

    wherein the integrating sphere module has a plurality of probes corresponding to the predetermine amount of the LEDs, thereby to test the electrical character of each LED by a manner of one by one.
