Description

具有同步信號的發光二極體控制電路及其封裝結構及其系統Light-emitting diode control circuit with synchronization signal, package structure and system thereof

本創作係有關於一種發光二極體控制電路及其封裝結構及其系統,特別是一種具有同步信號的發光二極體控制電路及其封裝結構及其系統。The present invention relates to a light-emitting diode control circuit and its package structure and system thereof, in particular to a light-emitting diode control circuit with a synchronization signal, a package structure thereof and a system thereof.

目前發光二極體燈串模組大致上可分為串聯式及並聯式兩種連結方式,而這兩種方式之發光二極體燈串模組也廣被使用者運用在大樓外觀、樹木、招牌及造景物上,以增添該等事物之外觀美。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.

而在習知串聯式的發光二極體燈串模組,是將多組的發光二極體燈串模組串聯連接在一起,而且發光二極體燈串模組的串聯數量乃是依據磐繞的物體體積大小而定,且在串聯後由第一個發光二極體燈串模組的控制器對所有的發光二極體燈串模組之發光二極體燈組進行控制。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.

雖然,此種串聯式的連結方式,使發光二極體燈串模組易於串聯使用,但是在使用過程中,只要有一組發光二極體燈串模組故障時,將造成控制訊號無法傳遞,致使該組故障的發光二極體燈串模組之後段的發光二極體燈串模組接收不到任何控制訊號,導致後段的發光二極體燈串模組皆無法被點亮。Although the series connection method makes the light-emitting diode lamp string module easy to be used in series, in the process of using, if a group of light-emitting diode lamp string modules fails, the control signal cannot be transmitted. The light-emitting diode string module in the subsequent stage of the LED module of the faulty group does not receive any control signal, and the LED module of the rear stage cannot be illuminated.

另外,在並聯式的發光二極體燈串模組是將多組的發光二極體燈串模組與該控制器並聯連結,每一個發光二極體燈串模組就要有一條控制線及定址線來控制。若是並聯10組的發光二極體燈串模組時,該控制器就必須利用10條控制線及10條定址線來控制10組發光二極體燈串模組。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.

此種並聯式在使用時,有一組發光二極體燈串模組發生故障時,將不會影響到其他發光二極體燈串模組的控制。但是,並聯的發光二極體燈串模組數量越多時,相對控制線及定址線越多,造成線路的複雜,不易製作,且成本高。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.

然而不論是串聯式或並聯式之連結方式,均需使用多數之電力線或訊號線,來達成使發光二極體燈串模組發光變化的目的。而在現今原物料上漲日益嚴重的情況下,能夠減少傳輸線的使用就能大大地降低成本。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.
