Disclosure of Invention
The utility model aims at a single power supply line voltage control constant current drive LED three-colour illuminator. The circuit structure framework of the LED constant current drive circuit is that different working voltages are input, window comparators in different threshold voltage ranges are connected, corresponding LED constant current devices are controlled, and the LED diodes are driven to emit light by constant current.
The working principle of the LED light-emitting diode control circuit is that three window comparators with different threshold voltage ranges are used for carrying out voltage selection control on different input voltages, the window comparators with different threshold values are controlled by different input voltages, and therefore the LED light-emitting diodes are controlled to emit light correspondingly.
The working power line of the window comparator is connected with the control line to form a lead wire which is a power line and a control signal line. The input ends of the three window comparators are connected with a 27V voltage stabilizing diode at the same time, namely when the input working power supply exceeds 27V, the three voltage stabilizing diodes penetrate through the three window comparators at the same time, the three window comparators are simultaneously switched on to work and are connected with the constant current driver, and the three LEDs emit light completely.
