内容記述 | In this paper, a constant illumination level control of a reading lamp is considered, with the microcontroller PIC, by continuously adjusting the illumination level on a desk from the filament lamp. The illumination, from the filament lamp, is transformed into the voltage by the phototransistor on the desk. From the voltage thus transformed, we can know the illumination level on the desk indirectly. For the purpose of constant illumination level control, the phase control of the AC voltage, in terms of the triac, is adopted. Since the transformed voltage through the phototransistor is small, the voltage is amplified by the operational amplifier. The amplified voltage is applied to the microcomputer PIC and A/D converted in the PIC with a resolution of 10 bits. The microcontroller program is implemented as follows. If the A/D converted value is larger than the reference input value, the phase delay of the AC voltage, applied to the filament lamp, is set to increase. Then the brightness of the filament lamp decreases, and vice versa. According to these adjustments of the illumination level on the desk, the feedback control of the constant illumination level from the reading lamp, is carried out. | |||||
