When the device is used, the power supply circuit is communicated with the power supply, and the illumination brightness of the simulated luminous source is regulated by the regulating device, so that the simulated luminous source emits strong light or weak light, and the test of the simulated luminous source under the two illumination environments of strong light and weak light on the solar panel is realized, so that the occupied space of a production line is reduced, and the working efficiency of testers is improved.
In some embodiments of the utility model, the regulating means comprises a voltage transforming means for controlling the input voltage of the analog light emitting source, the voltage transforming means being connected in series in the supply circuit. The brightness of the analog light-emitting source is related to the power of the analog light-emitting source, and under the condition that the resistance of the analog light-emitting source is fixed, the larger the voltage loaded on the analog light-emitting source is, the larger the power is, and the higher the brightness of the analog light-emitting source is.
