Light-intensity test device

The invention provides a light-intensity test device used for testing light intensity of emitting-light of a light source. The light-intensity test device comprises a light frequency converter, a micro processor, a displayer and an input device. The light frequency converter, the displayer and the input device are all connected with the micro processor. The displayer displays a color selection interface. The input device is used for inputting color selection parameters to the micro processor. The micro processor sends a control signal to the light frequency converter according to the color selection parameters. The light frequency converter selects a light wave in a corresponding color according to the control signal, converts the light wave into digital signals of different frequencies and transmits the digital signals to the micro processor. The micro processor obtains light intensity according to the digital signals and enables the light intensity to be displayed on the displayer.
