Hello everyone, I am Xiaobian Rong, today, let ’s introduce the problem of the perfect solution of the LED lamp beads that break the LED. The following is the summary of this issue and related issues. Let’ s take a look. Essence

1. Can LED lamp beads be broken? 2. How can LED lamp beads break one how to remedy 3. How to repair the LED lamp beads 4, what do the lamp beads of LED light bulbs be broken? Replace 5. How can the LED lamp break down? LED lamp beads can be used if it is broken?

LED lamp's power adapter output voltage current is supported by the light board. If the lamp beads are damaged, the short connection is temporarily made up, but it is possible to use it for a long time. Other lamp beads will accelerate other lamps. After receiving the current, the current voltage that should be affected by damaged lamps will be assigned to other lamp beads, and these lamp beads are in an overload state.

LED lamp beads are broken. How to remedy

3, if you have a certain basic knowledge of electronic, buy the same model of LED lights, hand a laptop, and welded again. But then again, there are many LED patch lamp components on each LED light bar, one or two, and it has no effect on the brightness.

If it is a civil LED ceiling lamp, the solarlight ball bubbles are broken, and the power supply is not connected to the situation. First observe the reaction of the lamps after power -on. If the LED light source will have individual lamp beads not bright, the probability is that the lamp board is broken, and the light source needs to be replaced. If the beads on the lamp board will be on, but it is slightly bright or shiny, the probability is that the driver is broken, and you need to replace the corresponding matching driver. The main attention is that the output voltage and current match. Happy New Year, mobile phone code, good luck

LED light bulb, generally connect multiple lamp beads and drive through the constant current drive. The current of each lamp bead is constant and the same size. If one of the lamps is damaged, it will affect the work of the entire lamp bead. For example, the small -power LED ball bubble lamp driven by the resistance of the voltage voltage voltage of the above figure, the six lamp beads are connected in series to connect the anti -voltage voltage voltage voltage circuit. Assuming that a lamp bead is in an open path, the remaining lamp beads will not light up. At this time, if you have the same specifications of lamp beads in your hand, you can remove the bad lamp beads. Assuming that there is no lamp bead in your hand, you can also use a wire or a small resistance welding of a tens of ω to the ends of the lamp bead, so that other undamaged lamp beads can be lit normally. Some LED light bulbs with large power are composed of multiple series LED lamp beads. If a bunch of lamp beads are damaged several lamp beads, then connecting the above method can cause the brightness of the string of lamp beads Different from the brightness of other string lamp beads, at this time, you can welded a stabilized voltage stabilization tube with a stabilization value of 2.7V at the position of each bad lamp bead (generally the forward voltage of the white light LED lamp beads is about 2.8V), This brightness is relatively consistent. It is best to use a patch to be encapsulated to facilitate welding.

If only one or two lamp beads are broken, we can use these two methods to repair:

1. Find the broken lamp beads, use a wire with a wire, The metal connected to both ends will be short -circuited. The effect of doing so is that most of the lamp beads can be lit normally. Only the broken individual lamp beads do not light up, which has little effect on the overall brightness.
