Rechargeable LED advertising light box

Basic concept of LED electronic light box

LED electronic light box is an advertising light box that uses LED light strips as light sources. It has the characteristics of energy saving, It has the advantages of environmental protection, high brightness and long life, so it has been widely used in the modern advertising industry. In the production process of LED electronic light boxes, resistance is a very important electronic component.

The role of resistors

A resistor is an electronic component used to limit current. Its main function is to limit the current within a safe range to pre vent the circuit from being overloaded and burning. In the LED electronic light box, the resistor can limit the current of the LED light bar to ensure the normal operation of the LED light bar.

How to use resistors

When making an LED electronic light box, the resistor needs to be connected in parallel with the LED light strip so that it can limit the current. The specific steps are as follows:

1. First, you need to pre pare the required resistors and LED strips.

2. Connect the resistor and the LED light strip in parallel. The connection method is to connect the two ends of the resistor to the positive and negative poles of the LED light strip respectively.

3. After confirming that the connection is correct, insert the LED light strip into the light box and turn on the power for testing.

4. If the test is normal and the LED light strip can glow normally, it means that the resistor plays a role in limiting the current.
