Barber pole lightboxes at entrance of barber shop are the symbols, there are many styles and shapes of barber pole lightboxes.
Light boxes that have been used for a long time will have various problems. Below we will explain these problems and their solutions to you in detail.
Problems and solutions of barber pole lightboxes
Barber pole lightboxes do not light up
- When LED lights in barber pole lightboxes do not light up, first make sure there is no problem with power supply.
If they are new installed ones,use electric pen to measure or install them to places to see if power supply is energized and and whether there is voltage in the circuit. - There is a problem with chip of LED lamp that causes it to not light up.
If current or voltage is too high or too low, it cannot light up normally. If lamp beads suddenly do not light up after turning on the light, you should consider
that the chip is broken and you can buy a new chip. Just replace it.

- SMD lamp beads of barberpole lightboxes are divided into pieces. Lamp beads on each piece are connected in series, and strings are connected in parallel.
If one lamp bead in this string is burned, it will cause this string to burn out. Lamp beads are not on. - If one lamp bead in each string is burned out, entire lamp will not light up. If one lamp bead in each string is burned out, there is a problem with capacitor or resistor on the driver.

If quantity of burnt lamp beads is not large, you can use a soldering iron to solder the two soldering feet behind the burned lamp bead. Together, if too many lamp beads are burned out, just replace them with a lamp bead board.

Then just change connecting wire. It should be noted that switch controls live wire and neutral wire is connected to the light.
- If there is no problem with circuit, it may be that LED lamp has self-induction current. Solution is to replace a 220V relay and connect coil in series with lamp.
