Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a schematic block circuit diagram of the present utility model;
Fig. 2 is the schematic block circuit diagram of the utility model control circuit;
Fig. 3 is the schematic block circuit diagram of second kind of embodiment of the present utility model.
The specific embodiment
With reference to figure 1 and Fig. 2, interior external control Campatible LED lamp decoration, can also can rearrange by built-in control signal control by a plurality of by the LED lamp group of external control signal control, each LED lamp group comprises control circuit respectively and along a plurality of illuminators of LED lamp component cloth, described control circuit comprises communication module, external control signal detection module and built-in display control module, communication module links to each other with the corresponding input port of built-in display module by outer system control signal detection module, the output port of built-in display module links to each other with illuminator, and communication module is provided with COM1; Under external state of a control, the COM1 by communication module between the adjacent LED lamp group connects communication; Under built-in state of a control, the communication disruption between the adjacent LED lamp group control circuit.Wherein communication module is used for receiving control signal corresponding under external state of a control, and external control signal detection module is used to judge whether communication module receives external control signal and show the default displaying contents or the demonstration signal of external control to control built-in display control module.Owing to all independently be provided with built-in display control module in each LED lamp group, be preset with fixing displaying contents in the module, be that each LED lamp group can both independently show the displaying contents that built-in display control module is default, and can link to each other by COM1 between the LED lamp group, when the control signal of COM1 is received in the winding of LED lamp, external control signal detection module is transferred to built-in display control module with external control signal makes built-in display control module interrupt the default displaying contents of output, transfers the control signal of sending according to external control to and shows.The utility model uses flexibly, and can set lamp decoration as required is various control forms such as pure external control, built-in and external control compatibility, pure built-in control.If under external state of a control, when indivedual LED lamp groups break down in the lamp decoration, just this lamp group all lamp groups subsequently all may not receive the control signal of external control, this moment, optional majority kind display mode carried out emergency processing, first kind is disconnected these lamp groups and can shows default displaying contents according to setting to transfer to automatically, second kind makes these LED lamp groups be disconnected unify display effect by first output control signal in these LED lamp groups, the third disconnects external governor circuit fully, as long as keeping all LED lamp groups powers simultaneously, so all LED lamp groups can both reach the unified effect that shows, for existing TW two wire lamp decoration can extinguish corresponding lamp group, to the less even not influence of whole display effect influence of lamp decoration.
Under external state of a control, also comprise external governor circuit, external governor circuit is connected with the COM1 of one of them LED lamp group, external governor circuit can adopt the mode of online or off line, on-line mode is that computer is linked to each other with external governor circuit, computer is sent to external governor circuit with displaying contents and the control information that edits, and is converted into serial communication signal by external governor circuit, is sent to the COM1 of LED lamp group then by COM1.Off-line mode is stored in required content displayed on the storage card, storage card is inserted in the external governor circuit, be provided with storage card in the outer circuits and read circuit, by after its reading displayed content also being the COM1 that is sent to LED lamp group by the back by COM1.Each LED lamp group all can judge whether COM1 exists correct signal of communication by external control signal detection module when work, if exist, this LED lamp group will be controlled by external governor circuit so, otherwise this LED lamp group will show the displaying contents that presets in the built-in display control module.
Control circuit in the LED lamp group comprises communication module, external control signal detection module and built-in display control module or the like, the utility model preferably adopts chip microcontroller, above-mentioned module can be integrated on this single-chip microcomputer, only need to realize function corresponding, saved manufacturing cost and the complexity that has reduced circuit greatly by software setting to single-chip microcomputer.
In addition, because the driving force of single machine output end is limited, if the quantity of illuminator is more, be difficult to rely on merely chip microcontroller to drive, therefore need to add illuminator and drive chip, the corresponding signal line of single-chip microcomputer drives chip with illuminator and links to each other, and the output port that illuminator drives chip links to each other with illuminator, with reference to Fig. 3.What illuminator drove chip mainly is that the output signal of single-chip microcomputer is amplified, and obtains bigger drive current, to satisfy the needs of a large amount of illuminator display drivers.
