Fig. 2 is the mixed light control system functional-block diagram of the utility model.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts The every other embodiment obtained, shall fall within the protection scope of the present invention.

It please refers to Fig.1 and Fig. 2, the embodiments of the present invention, a kind of LED display 1 of COB light source, including array COB light source 10, a face connection unit control panel 20 of the backlight of COB light source 10, unit control panel 20 is connected with power supply 30, single First control panel 20 is integrated with mixed light control system 50, and mixed light control system 50 includes circuit module below：

Music acquisition circuit module 501, for acquiring the music signal in environment；

Comparator circuit module 502, for comparing the music signal received and preset music signal, if will When the music signal received is more than preset music signal, start mixed light circuit module 503；

Mixed light circuit module 503, for starting mixed light pattern, so that 1 accompanied by music of LED display generates regular movements.

Music acquisition circuit module 501 includes sound transducer, analog-digital converter, microprocessor chip, wherein sound passes Sensor receives the voice signal in environment, and the voice signal is carried out analog-to-digital conversion, microprocessor chip by analog-digital converter The digital quantity will be received to carry out except being sent to the comparator circuit module after processing of making an uproar.

The digital quantity received is carried out digital-to-analogue conversion into comparison voltage, preset music letter by comparator circuit module 502 Number be converted into the voltage of benchmark, the two is input to comparator module and is compared, if the music signal received be more than it is preset When music signal, start mixed light circuit module 503.
