Description

Light-emitting diode control circuit and its packaging structure and system

technical field

The utility model relates to a light-emitting diode control circuit, its packaging structure and its system, in particular to a light-emitting diode control circuit with carrier signal control, its packaging structure and its system.

Background technique

At present, LED light string modules can be roughly divided into two connection methods: serial connection and parallel connection, and these two types of LED light string modules are also widely used by users on building exteriors, trees, signboards and landscaping objects. To add to the beauty of things.

In the known series-type LED light string module, multiple groups of LED light string modules are connected in series, and the number of LED light string modules connected in series depends on the volume of the coiled object, and after the series is connected by The controller of the first LED light string module controls the LED light groups of all the LED light string modules.

Although this kind of series connection method makes it easy to use the LED light string modules in series, but in the process of use, as long as one group of LED light string modules fails, the control signal will not be transmitted, resulting in the failure of the group of light emitting diodes. The rear LED lamp string modules of the diode lamp string modules cannot receive any control signal, so that none of the LED lamp string modules in the rear segment can be turned on.

In addition, in the parallel LED light string module, multiple groups of LED light string modules are connected in parallel with the controller, and each LED light string module needs to have a control line and an address line to control. If 10 groups of LED light string modules are connected in parallel, the controller must use 10 control lines and 10 addressing lines to control 10 groups of LED light string modules.

When this kind of parallel connection is in use, when a group of LED light string modules fails, it will not affect the control of other LED light string modules. However, when the number of LED light string modules connected in parallel increases, there are relatively more control lines and addressing lines, resulting in complicated wiring, difficult fabrication, and high cost.

However, regardless of the connection in series or in parallel, a large number of power lines or signal lines are required to achieve the purpose of changing the light emission of the LED light string modules. In today's situation where raw materials are rising day by day, reducing the use of transmission lines can greatly reduce costs.
