1. Compared with the driving current of the LED, the advantage of the series circuit is that the current is stable. The drawback is that if one of the LEDs is damaged, all LEDs will not illuminate, but will not affect the lifetime of the other LED.
2. The advantage of parallel circuits is that the failure of any LED will not affect the application of other LEDs. The drawback is that if no current limiting resistor is added, any LED will be damaged, the current across the other LED will increase, and the other LED will be burned. And because the driving voltage of a single LED is very low, most of the voltage will be formed to do useless work, which is also a waste of money.
The 3-series parallel circuit is a general-purpose circuit for LED plant growth lamps. In the absence of daylight, led lamps can act as daylight, allowing plants to grow normally or better. This kind of lamp has strong roots, encourages, regulates flowering and flower color, promotes fruit ripening, coloring, and enhances the taste and quality! Hydroponic vegetable light environment is one of the important physical environmental factors indispensable for plant growth and development. Controlling plant morphogenesis through light quality regulation is an important technology in the field of facility cultivation; plant growth lamps are more environmentally friendly and energy-saving, LED plants Lights provide photosynthesis to plants, promote plant growth, reduce the time spent on plant flowering, and increase production! In modern construction, it is an indispensable product for crops. Because multiple LEDs are selected in series to form a group, then parallel with the other groups. It maximizes the utilization of the power supply voltage and reduces the useless power loss. Selecting several LEDs in series ensures that the driving current of these LEDs is universal, which is beneficial to stabilize the current of the LEDs and thus ensure the service life of the LEDs. After the LED plant growth lamp groups are connected in series, they are connected in parallel with other groups to ensure that one group is damaged without affecting the normal application of other groups. Since each group has a finite current resistance, the lifetime of the other group is not affected by a group of damage.
