Embodiment 2
[0057] In Embodiment 2, the drive circuit for plant lighting may include multiple adjustable circuits, and the multiple adjustable circuits are used to connect multiple groups of loads in one-to-one correspondence. Such as Figure 8 As shown, n adjustable circuits are used to connect n groups of loads one by one. When there are n LED lamp loads, each LED lamp load corresponds to a chopper switch and an adjustable voltage source. Multiple LED loads share A constant voltage source Qs. In the multi-output drive circuit, the voltage of each LED lamp is allowed to be different. Through the voltage adjustment at both ends of the adjustable voltage source in each branch, the voltage difference of the LED lamp of this road is made up, so that the voltage of each LED lamp can be adjusted. The sum of the voltage source and the LED lamp voltage is equal to the parameter voltage of the constant voltage source. Each group of LED loads may include multiple LED lamps connected in series. ...
