What are the precautions for the led light box making tutorial?

Introduction: Every night, we can see colorful led light boxes. There are many kinds of LED light boxes. Its existence adds a beauty to our night, makes our life more exciting and makes us see the name of the store more clearly. Do you know how to make an LED light box? Let's take a look at the manufacturing method of LED light box.

First, the manufacturing method of LED light box:

Step 1: Prepare the tools needed to make LED light boxes. The tools that need to be prepared first are acrylic board, plastic board, etc., and other insulating materials can also be used to replace these tools. Then choose your favorite words and burn them with single-sided tape, then stick them on the aluminum-plastic board and punch holes.

Step 2: After the drilling operation is completed, connect the led lamp, arrange the positive and negative electrodes of the lamp in a certain way, and then connect the lamp feet with tin.

Step 3: After welding the lamp legs, group them. It is necessary to group the serial numbers of LEDs with different colors, and remember that it cannot exceed its maximum serial number.

Step 4: After grouping, connect the resistors in series and connect the corresponding resistor string with the LED.

Step 5: After connecting the resistors in series, connect the controller. Firstly, connect the positive pole of the controller with the positive pole of the led lamp, and then connect the negative pole of the controller with the negative pole of the led lamp. After connecting the positive and negative poles, connect the output line with the negative poles of the three groups of side lights, and then connect the positive poles of the side lights with the positive poles of the protagonist.

Step 6: Debug after checking that there are no errors in the connection. First, power on. When we saw the light on, we measured the current. We need a multimeter to measure its current. If its current is abnormal, we need to debug it. When debugging, we need to increase the resistance. When the current displayed by the multimeter is normal, we can complete the debugging, so that the LED light box is completed.

Second, the matters needing attention when making LED light boxes:

If the LED light box is completed and its light doesn't work, then we need to use it to check its controller. We need to connect the black pen to the corresponding green line and the red pen to the corresponding red line. If the multimeter indicates correctly, it means that the multimeter is normal. Then we need to control the black pen and check the voltage of the red pen. If the difference is too big or there is no voltage, we need to replace the LED.

The above is the manufacturing method of LED light box. Have you learned? Friends who like LED light boxes, come and learn.
