Hello everyone, I am Xiaobian Qinmeng today, let ’s introduce LED lamp beads to prevent the change of LED lamp beads that can use how big the resistance can be changed. The following is the summary of Qinmeng on this issue and related issues. Let’ s come together. have a look. Catalog of the article:1. LED lamp beads are broken. Use a large resistance to replace it. 2. LED lamp beads are replaced with maintenance with how big resistance. 3. LED lamp beads are broken with resistance. Can it be replaced by resistance 5. How big the LED light is broken LED lamp bead is broken. Use the resistance to replace it. The resistance value r \u003d u/i. In the formula, U is the normal working voltage of the lamp bead, and i is the current when the lamp bead is shining normally.LED lamp beads are broken. The maintenance of how big the resistance is replaced by the resistance For 0.5W, the voltage is 3V LED lamp beads after damage. LED lamp beads are broken. How big the resistance is used for LED lamp beads. Resistance r \u003d u/i. In the formula, U is the voltage of the lamp beads, and i is the normal emitting current of the lamp bead.LED lamp beads can be replaced by resistance , but after replacement with resistance, other LED lamp beads will be damaged and will cause a chain reaction. The lamp bar is completely scrapped. Because of the power supply to the light bar is a constant current source, the voltage changes, the output current remains unchanged, the lamp bar is equivalent to a variable resistor. After using a fixed resistor, it will destroy the working conditions of other lamps. When there are many working conditions for lamp beads, LED lamp beads will be damaged one after another.LED lamp is broken, how big the resistance is broken LED lamp beads, you can use the resistor to replace it. Its resistance value R \u003d U/i. In the formula, U is the voltage of the lamp beads, and i is the current when the lamp bead is shining normally. The above is the editor of Tiancheng's answer to the LED lamp beads from changing the LED lamp beads. How big the resistance can be replaced with the question and related questions. I hope it is useful to you [Responsible editor: Qinmeng] |
