In order to solve problems of the prior art and deficiency, the object of the present invention is to provide a kind of LED indicating device that is used for music equipment with low cost, easy to use.The present invention has realized that abundant more color shows and control, and shades of colour can carry out rhythmical flicker along with the broadcast of melody.
In order to realize the foregoing invention purpose, technical scheme of the present invention realizes as follows:
A kind of LED indicating device that is used for music equipment, the power module that comprises control module that N output control signal can be provided and power for each functional module.Its design feature is, also comprises 2
NIndividual processing module and 2
NIndividual LED light group, described each LED light group by the LED light of N different colours closely discharging form, and the ratio of the efficient lighting area sum that guarantees N LED light self and the area of their minimal convex polygon of encirclement is greater than 50%.Described 2
NEach processing module in the individual processing module all has N output.Described control module sends to described 2 with N output signal
NThe input of each processing module in the individual processing module.Described 2
NIndividual processing module is carried out conversion process to described control signal, and each processing module sends to described 2 with the control signal after the conversion process respectively
NThe LED light group of the correspondence in the individual LED light group, wherein the output control signal of N output in each processing module is controlled N LED light in the corresponding LED light group respectively.
Above-mentioned each processing module all has 2*N input.Have N input to receive the control signal of control module in above-mentioned each processing module, N input can preestablish in addition, also can be set dynamically by program by control module.Above-mentioned each processing module all is the combinational circuit that exclusive-OR operation is carried out in a step-by-step.
The present invention can also comprise an amplifier that the output current of described control module is amplified.
N LED light in the above-mentioned LED light group can be arranged in parallel.
N LED light in the above-mentioned LED light group can be circular or square.
Above-mentioned N can be 3.3 LED light in the above-mentioned LED light group can be red, green, blues.
The present invention is owing to adopted 2
NIndividual processing module is carried out conversion process to the control signal of control module output, has so just produced 2
NKind output control signal, and this 2
NPlant the output control signal and control its corresponding LED light group respectively.Like this, just have 2
NIndividual LED light group shows simultaneously according to the music of being played.Each LED light group is closely discharged by the LED light of N different colours and is formed, and each LED light group has only a LED lamp bright with regard to existing like this, has only two LED lamps bright, several states such as all LED lamp Quan Liang.Because these several LED light arrangements are very tight, when the while more than two is bright, seem to be exactly another new color.Like this, each LED lamp group can show (2
N-1) plants color.Therefore, the present invention has realized that abundant more color shows and control, and shades of colour can carry out rhythmical flicker along with the broadcast of melody.Of the present invention simple in structure, with low cost, can improve existing apparatus easily.
