Abstract

汽车燃油容量光电传感显示器是根据光敏电阻对有光(可见光)照射时,其电阻值变小(亮阻)呈“通”的状态,无光照射时,其电阻值变大(暗阻)呈“断”的状态设制的,当油箱油量“满”时,光线全部照射设定的若干光敏电阻,显示器LED全部亮;当油箱“空”时,光线全部被遮挡,显示器LED全部不亮,当油箱油量部分时,光线部分照射光敏电阻,显示器LED部分亮。
A photoelectric sensitive display for motorcar fuel content is characterized in that when a photoconductive resistor is irradiated by lights (visible lights), the resistance (bright resistance) of the photoconductive resistor pair gets smaller and is in an ''ON'' state, when no light irradiates the photoconductive resistor pair, the resistance (dark resistance) gets bigger and is in an ''OFF'' state; when the oil in an oil tank is ''FULL'', all the lights irradiate a plurality of predetermined photoconductive resistors, all of display LEDs are bright; when the oil tank is ''EMPTY'', all the lights are shielded and all the display LEDs are dark; when the oil in the oil tank is ''PART'', a part of the lights irradiate the photoconductive resistors and a part of the display LEDs are bright.
