Abstract
The utility model discloses an LED system control panel testing apparatus comprising a PCB, signal joints and display modules. Welding apertures for the signal joints are arranged in the PCB. The signal joints are welded on the back side of the PCB. The display modules are arranged on the front side of the PCB. The signal joints include a plurality of signal ports which are in one-to-one corresponding connection with output ports of an LED system control panel. Each display module comprises a plurality of LED indicating lamps and resistors. One resistor and one LED indicating lamp are in series connection between each port of the signal joint and a signal ground. Anodes of the LED indicating lamps are connected with the signal ports. A cathode of each LED indicating lamp is connected to one end of each resistor. The other end of each resistor is connected to a signal ground. Through the observation of a switch-on rule of the LED indicating lamps, signal communication statuses of the system control panel are determined and fault types are also determined; the failure rate of finished products is substantially reduced; manpower resources are saved; and properties of convenience and high efficiency are realized.
