When we buy LED plant lights, what we care most about is the quality of the lamp beads, the ratio of the lamp beads, the wattage of the lamp beads, etc., but we ignore the well-known principle-the power supply of the plant light is one Participants of a complete LED plant light have extremely important significance.
The LED plant light power supply is an electronic component that uses resistance and circuit connection to control the voltage and current to achieve the purpose of stabilizing the power of the lamp beads. It is also called the LED plant light power supply. The LED plant light power supply has two core functions, voltage transformation and rectification.
Power transformation of LED plant light
We know that each LED plant light bulb can withstand a very small voltage and has its rated voltage. The voltage of 1WLED plant light bulbs is about 2.9 to 3.5V, the working voltage of 3W bulbs is 3.1 to 4.5V, and the household voltage is generally About 220V, directly acting on the LED plant lamp beads will inevitably burn out the lamp beads, so the power supply must be used to transform the voltage so that the voltage acting on a single lamp bead is within the range of the lamp bead's rated voltage.
Transformation is not a simple series connection method, because we all know the principle of series partial pressure, but in the actual use process, it is inevitable that some LED plant lights have the shortest lifespan, and some have the longest lifespan. If it is simple All the lamp beads are connected in series. After one lamp bead is damaged, all other LED plant lamp beads will be unusable. Therefore, the function of the power supply is to ensure that each LED plant lamp lamp bead can reach the rated voltage range, and each The lamp beads can operate independently, and the rated voltages of the red and blue lamp beads are different, and the power supply needs to be controlled separately, so that each LED plant lamp lamp can work normally.
LED plant light power supply rectification function
In our country, whether it is household electricity or commercial electricity, three-phase alternating current is used, and LED plant lamp beads and all LED products can only use direct current, so it is necessary to use LED plant lamp power to convert alternating current into direct current. It can be used for LED plant lamp beads.
Like the control voltage, each lamp bead needs to be individually controlled to ensure the stability of the lamp when it is used.
Each lamp bead of the LED plant light must reach its rated power to fully emit light, and to efficiently fill the plant with light. According to power (P) = voltage (U) X current (I), it can be known that power is determined by voltage and current. The same decision, so it is necessary to control the voltage and current to give full play to the maximum effect of the LED plant lamp beads and ensure the maximum use efficiency of the LED plant lamp.
