Led plant lamp beads determine the effect of fill light, led plant lamp power determines the life and death of the lamp beads
When we buy led plant lamps, we always care about the quality of the beads, the ratio of the beads, the wattage of the beads, etc., but we ignore the well-known truth that the power supply of the plant lamps, as the participants of a complete led plant lamps, has extremely important significance.
Led plant lamp power supply is an electronic component that uses resistance and circuit connection to control voltage and current to achieve the purpose of stabilizing lamp bead power, also known as LED plant lamp power supply. Led plant lamp power supply has two core functions, voltage transformation and rectification.
Voltage transformation effect of LED plant lamp power supply
We know that the voltage that each LED plant lamp bead can withstand is very small and has its rated voltage. The voltage of 1wled plant lamp bead is about 2.9 to 3.5V, and the working voltage of 3W lamp bead is 3.1-4.5v, The household voltage is generally about 220 v. if it directly acts on the LED plant lamp beads, it will inevitably burn out the lamp beads. Therefore, it is necessary to use the power transformation to make the voltage acting on a single lamp bead be within the range of the rated voltage of the lamp bead.
Rectification function of LED plant lamp power supply
In China, both domestic and commercial electricity use three-phase alternating current, and led plant lamp beads and even all LED products can only use DC power. Therefore, it is necessary to use the LED plant lamp power supply to convert alternating current into direct current to supply LED plant lamp beads.
Like the control voltage, each lamp bead needs to be controlled separately to ensure the stability of the lamp when it is used.
Each lamp bead of LED plant lamp must reach its rated power in order to fully emit light and efficiently supplement light for plants. According to the power, the power is determined by the voltage and current. Therefore, it is necessary to control the voltage and current to give full play to the maximum effect of LED plant lamp beads and ensure the maximum efficiency of LED plant lamps.
