置用輝度調整装置。 A photo sensor has a built-in light-receiving element that converts light energy into electrical energy, and a voltage signal from this photo sensor is branched and placed in parallel with the branched signal to set the brightness of the display device in stages. a plurality of illuminance setting volumes; a voltage comparator that compares the voltage signal of the photo sensor and the voltage signal of the illuminance setting volume to determine the magnitude; and a signal selected by comparison by the voltage comparator. A plurality of photocouplers arranged in parallel send out the signal to a light emitting element, and receive the above signal with a light receiving element electrically insulated from the light emitting element and send it to an input device, and the plurality of photocouplers. A luminance device for an outdoor display device, which is equipped with an input device that combines voltage signals from and inputs a signal setting value, a conversion device that converts the setting value into brightness, and a display device that projects the output signal from this conversion device on a screen. Adjustment device.
