Description

Light-emitting diode lamp and string and system with programmable function 【0001】

The invention relates to a light-emitting diode lamp and a light string and system, in particular to a light-emitting diode lamp and a light string and system with a burnable function.

【0002】

At present, the LED array of LEDs can be roughly divided into two types: tandem type and parallel type. The two types of LED arrays are also widely used by users in the appearance of buildings and trees. Signs and landscaping to add to the beauty of these things.

[0003]

In the conventional series of LED light string modules, a plurality of sets of light-emitting diode string modules are connected in series, and the number of series of light-emitting diode string modules is based on The volume of the wound object depends on the size of the object, and after the series connection, the controller of the first LED array module controls the LED groups of all the LED strings.

[0004]

In addition, in the parallel type light-emitting diode lamp string module, a plurality of sets of light-emitting diode lamp string modules are connected in parallel with the controller, and each light-emitting diode lamp string module has a control line. And address lines to control. If 10 groups of LED array modules are connected in parallel, the controller must use 10 control lines and 10 address lines to control 10 groups of LED arrays.

[0005]

When such a parallel type is used, when a group of light-emitting diode lamp string modules fails, the control of other light-emitting diode string modules will not be affected. However, the greater the number of parallel LED strings, the more the control lines and the address lines are, resulting in complicated lines, difficult to manufacture, and high cost.

[0006]

However, whether it is a series or parallel connection method, a majority of power lines or signal lines are required to achieve the purpose of illuminating the LED module. In the current situation of increasing raw materials, the use of transmission lines can be reduced to greatly reduce costs.

【0007】

Later, a light-emitting diode driving device capable of transmitting an illuminating signal (including illuminating data and address data) by a power line is proposed; when the illuminating diode driving device is manufactured, the local address data must be burned. The light-emitting diode driving device is recorded; when the light-emitting diode driving device receives the light-emitting signal, the light-emitting diode driving device checks whether the address data is the same as the local address data; if the address data and the local address data Similarly, the LED driving device drives the LED according to the illuminating data.

[0008]

However, the above disadvantage of the local address data being burned into the light emitting diode driving device before the light emitting diode driving device is completed is: once the light emitting diode driving device is manufactured, the local position The address information cannot be changed. Therefore, it is very inconvenient for warehouse management. Moreover, it is also very inconvenient for assembling a large number of LED driving devices, because the operator must carefully check the local address data of each LED driving device to avoid assembling unnecessary light. Polar body drive.
