Abstract

The utility model relates to an LED mixed light synchronization device. The device comprises at least two DMX controllers which are interconnected through cables and arranged inside corresponding LED lamps (1). The LED mixed light synchronization device adopts the electrical cables of DMX standard protocol as both the DMX signal transmission lines and the synchronization signal lines, achieves the synchronization of light mixing of different lamps, omits the use of synchronization cables, reduces the difficulty in construction and installation and provides convenience for maintenance.

Description

A kind of LED mixed light synchronizer

Technical field

The utility model relates to the LED illumination, is specifically related to a kind of LED mixed light synchronizer.

Background technology

Various light mixing methods appear in the LED industry at present, the most frequently used method one is to utilize three basic colors red, green, the mixing of blue three primary colors forms various light, the 2nd, be substrate with the blue-light LED chip, the certain density phosphor powder layer of outer enclosure by blue photostimulable phosphor layer, produces the white light of different-colour.When realizing the mixed light of same effect with different lamps, must use method for synchronous, make different lamps send identical light, method current on the market is to send synchronizing signal from a unit in star-like mode, the circuit complexity, synchronizing cable is installed very inconvenience.

On the other hand, digital multi-channel transmission signals (DMX), especially DMX512 standard agreement can pass through many DMX of control signal cascade light fixture, can cooperated with LED DMX driving group constitute a complete DMX control system, be widely used in the large-scale LED outdoor decoration engineering.

The utility model content

The utility model technical issues that need to address are, how a kind of LED mixed light synchronizer is provided, and can simplify synchronizing cable, reduce the project installation difficulty.

The utility model technical problem solves like this: construct a kind of LED mixed light synchronizer, comprise by the interconnective DMX controller that is built in more than in the corresponding separately LED light fixture of cable.

According to the synchronizer that the utility model provides, be provided with a DMX master controller that is used to send synchronous control signal in the described DMX controller.

According to the synchronizer that the utility model provides, described DMX master controller connects the DMX protocol devices that is used to provide the external sync control signal, also can be that DMX master controller oneself produces synchronous control signal.

According to the synchronizer that the utility model provides, be provided with the DMX slave controller that one or more are used to receive synchronous control signal in the described DMX controller.

According to the synchronizer that the utility model provides, described cable is the DMX standard cable.

According to the synchronizer that the utility model provides, described ways of connecting is series, parallel, star or its mixing connected mode.

The LED mixed light synchronizer that the utility model provides utilizes DMX standard agreement cable, when transmitting the DMX holding wire, synchronous signal line as light fixture, realize the synchronous mixed light of different lamps, simplify synchronizing cable, reduce the project installation difficulty, be convenient to simultaneously safeguard.

Description of drawings

Further the utility model is elaborated below in conjunction with the drawings and specific embodiments:

Fig. 1 is the utility model LED mixed light synchronizer syndeton one schematic diagram;

Fig. 2 is the utility model LED mixed light synchronizer syndeton two schematic diagrames;

Fig. 3 is the interior DMX main controller controls program circuit schematic diagram of LED mixed light synchronizer in the syndeton shown in Figure 1;

Fig. 4 is the interior DMX slave controller control program schematic flow sheet of LED mixed light synchronizer in the syndeton shown in Figure 1.

Embodiment

As illustrated in fig. 1 and 2, the utility model LED mixed light synchronizer specific embodiment is partly formed by 3: DMX512 normal line and be built in DMX512 master controller and DMX512 slave controller in the corresponding separately LED light fixture 1, and its synchronizing process is:

The first step, the DMX512 master controller sends the mixed light technical parameter, sends synchronous control signal simultaneously, and it is converted to serial control signal and transmission;

In second step, serial control signal is passed to the DMX512 slave controller through DMX512 standard electric cable.

In the 3rd step, the DMX512 slave controller is accepted to upload the serial control signal of sending here from DMX512 standard electric cable, and it is decoded and conversion of signals, control light fixture mixed light, thereby the synchronous mixed light between the realization different lamps.To reach variable color or mixed light unanimity.

The corresponding two kinds of working methods of this specific embodiment, wherein:

㈠ self-regulation, no external synchronization source, the concrete connection as shown in Figure 1

When being used for self-adjusting system, DMX512 master controller diverter switch switches to the self-regulation pattern, and the DMX512 master controller is only accepted the control signal of self-regulation pattern, handles the synchronous control signal of self-regulation pattern, thereby realizes the mixed light control of light fixture;

DMX512 slave controller diverter switch is converted to the self-regulation pattern simultaneously, toggle switch lost efficacy, the DMX512 slave controller is only accepted the synchronous signal information that master controller sends over by the DMX512 cable, handles synchronous control signal information, thereby realizes the synchronous mixed light between the light fixture.

㈡ is outside to be regulated, and external synchronization source is arranged, the concrete connection as shown in Figure 2

When being used for outside the adjusting, master controller is the DMX512 pattern by switch transition.As shown in Figure 3, the DMX512 master controller is only accepted the control protocol from the DMX512 of external synchronization source, and carry out synchronous mixed light according to external sync information, and control signal changeed by the DMX512 standard cable be sent to the DMX512 slave controller, realize control to light fixture;

Slave controller switches to the DMX512 pattern by switch simultaneously, and stir the address with toggle switch, thereby determine the address (DMX512 pattern) of slave controller, as shown in Figure 4, handle the DMX512 control signal of autonomous controller, thereby it is unified both can to have reached light fixture, can reach the purpose of the different controls of light fixture again.

The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
