In step 220, collating pulse width modulated cycle timer.In case timer reaches the terminal point in cycle fixed time, node index one of (in this example in 8 light modules of expression) increases [step 230].If node index reaches numerical value 9, perhaps in other situation, an expression node index value exceeds the number of light modules 12 in the system, and node index is reset to numerical value 1[step 240 and 250].After increasing node index, each red, green and blue LED cycle of light modules of being represented by node index increases [step 260].
In step 270 and 280, whether definite cycle for blue led should be reset and be back to zero.If this is the case, the value of the blue led of being represented by node index flushes to the initial value of specific ramp pattern.In other words, in case fixed time period is over and done with, display pattern is reset to initial value.
In step 290,300 and 310, determine 3 kinds of LED (red, green and blue) ramp value whether less than periodic quantity.Generally speaking, whether decision LED should open or close.After these steps are finished, in step 220, check the pulse width modulation period timer, and the process that repeats to discuss just now.
In the embodiment that also has, may change the display pattern of light modules 12.In embodiment so, whether mode switch is checked on step 320 so that determine and is changed.If mode switch changes, surpass the increase of effective patterns number mode value or be reset to 1[step 330] if increase the back value.Light modules was set to the initial value [step 340] of selected new model then before process repeats.

Choose and transmit modulated AC signal message
In the present invention on the other hand, be provided for the system and method for the information of choosing from modulated AC signal, so that this information is communicated by letter via luminescent system of the present invention subsequently.In one embodiment, as shown in figure 19, circuit 500 is configured to accepts and controls modulated AC signal.Circuit 500 electric interfaces are in the suitable node of microcontroller (for example microcontroller shown in Fig. 9 A).Microcontroller makes a plurality of RGB light emitting modules (for example module 12) directly produce illumination effect in response to what measured by circuit 500 through the many aspects of modulated AC signal successively.
In one embodiment, modulated AC signal is a binaural audio signal, and each sound channel is received by independent circuit 500 by this.Yet those skilled in that art are appreciated that various audio frequency, video and other and can be received by circuit 500 or its equal configuration through modulated AC signal.In vision signal embodiment, circuit 500 comprises the audio socket of received signal, or monophony or stereo.Perhaps, signal also can be received by microphone 520.In this embodiment, each in two sound channels (for example L channel and R channel) is by independent reception.It will be understood by those skilled in the art that audio signal can comprise single sound channel or even 5,6,7,8 or more sound channel, each sound channel all is that a kind of modification by circuit 500 receives.Perhaps, operational amplifier can be mixed two sound channels as summing amplifier (not shown).Selectively, can audio signal be feedbacked via earphone socket 570.
After reception, signal flow is crossed has the potentiometric operational amplifier 530 that is used to gain and adjusts.Perhaps, can be by microcontroller (not shown) adjustment that gains.In operational amplifier 530 back levels, signal is divided into two independent paths by double diode 540.As shown in figure 19, the audio signal parts by path A keeps constant substantially.Otherwise as shown in figure 19, the audio signal by path B flows through low pass filter 580.Low pass filter can comprise various known configurations.As shown in figure 19, filter 580 comprises two resistors and a capacitor.Low pass filter 580 is as peak point detector circuit work, and peak point detector circuit is by removing the signal highest frequency audio signal parts " smoothing " that makes through path B.The practice effect of filtering causes following the trend that enters audio signal substantially through the audio signal parts of path B, sharp-pointed transition is smoothed in signal fall.Its result as shown in figure 20.Low pass filter is used for the average trend in very similar other field such as finance of the running of AC signal processing.Two kinds of means all produce and remove short term oscillation, only stay the more smooth signal pattern of long-term trend.Although this embodiment adopts low pass filter, according to desirable effect, other filter and filtering method also are feasible.
By two paths of signals (through the part of path A with through the part of path B) is flow through with the two-way voltage signal relatively and determine which bigger comparator circuit 550 (for example operational amplifier) but filter effect among the measuring route B.As shown in figure 20, exporting 600 signal responses from the comparator of circuit output 560 also can be deciphered by microcontroller in the volume and/or the frequency of signal.Specifically, during the amplitude of path A signal or volume were greater than the amplitude of path B signal or volume, comparator output produced volume peak point, consults the some X of Figure 20.On the contrary, during the amplitude of path A signal or volume were less than the amplitude of path B signal or volume, comparator output produced volume decrease, consults the some Y of Figure 20.As shown in figure 20, comparator output 600 is digital signals, and signal is " conducting " or " 1 " during volume peak point by this, and is " disconnection " or " 0 " during volume decrease.
In one embodiment, circuit output 560 as described above interface in microcontroller with the driven for emitting lights system, thereby obtain desirable illumination effect.For example, the present invention provides a kind of " graphic equalization demonstration " function by the signal of being exported with the visual manner transmission.The output signal corresponding with each sound channel in two audio tracks can be used to a plurality of relevant RGB nodes in the driven for emitting lights configuration.A plurality of relevant RGB nodes each (for example module 12) comprise three LED.For example, shown in Figure 21 A and Figure 21 B, each in the two graphic equalization demonstration luminous tube 700 comprises the module 12 of a plurality of linear configurations, and they are driven to obtain the graphic equalization display effect by microcontroller as described above.
Figure 21 A is provided to transmit the information of relevant two-way audio sound channel with each of two luminous tubes 700 shown in Figure 21 B.As previously mentioned, can adopt summing amplifier selectively two audio tracks to be mixed, the relevant in this case information through mixed signal can be transmitted by single luminous tube 700, and is such shown in Figure 21 C.Relative to each other another example of a plurality of relevant RGB nodes of linear configurations is a pipe 50, consults Figure 18 A.
Get back to Figure 21 A now, the RGB module 12 in the pipe 700 is driven by the microcontroller of received audio signal, and described audio signal is by circuit 500 controls and output.When not having audio signal or audio signal to be essentially to mourn in silence, all light emitting modules 12 are actuated to show a kind of color.In one embodiment, " mourning in silence " look is blue, but can select other color showing to mourn in silence.In order to obtain this effect, all blue leds in the pipe 700 in the linear array of RGB node (module 12) are driven to full conducting and manage the red and green LED of in 700 all and are driven to full disconnection.Figure 21 A is illustrated in the pipe 700 that blue led in pipe 700 bottom 710 modules is lighted (rather than redness or green LED), and all blue leds are lighted (rather than redness or green LED) in the bottom 710 of pipe 700 and top 720 modules.With each module drive is that monochromatic effect produces blue " background " look, shows on it that audio frequency subsequently changes.
As showing the audio signal that amplitude (volume) increases, the microcontroller that receives institute's control audio signals from circuit 500 will manage blue led 700 bottoms 710 and be driven and be full disconnection, begin and will move to the highest module point-blank from the module of managing 700 foots 710.When the blue led of module is driven to full disconnection, shown in Figure 21 B, the red LED of equal modules is driven to full conducting substantially simultaneously.Blue led in one or more modules in pipe topmost 720 keeps lighting, and up to enough high and/or lasting enough periods of the volume of audio signal, this will be described hereinafter.In this embodiment, redness is " volume " look of the amplitude chosen from audio signal of reflection, but also can select the amplitude of other color with the expression audio signal.
This process produces a kind of visual effect that changes the red bar of height, and it corresponds directly to the amplitude (volume) of audio signal and shows in the blue background.In this embodiment, only two kinds of colors (red and blue) are used to tell on.Yet each of a plurality of modules 12 can produce any color in essence in the pipe 700.Therefore, red, green and blue being used for various combination allows any desirable color is acted on balancing pole color (" volume " look) and background color (" mourning in silence " look).
In addition, but balancing pole color and background color can change by volume, change or change based on other measurement characteristics of audio signal (for example frequency) in time.Can under a plurality of occasions, install or use visual effect, for example comprise loud speaker frame, wall hanging, panel shape display and other ornamental object functional or the non-functional object.
Relevant volume peak point or the information of volume decrease duration are transmitted in configuration of the present invention as mentioned above, rather than simple information volume.By the response volume increase the duration or duration of reducing of volume and the transmission of transfer vision information produces the illumination effect of expressing the meaning.For example, when the volume of audio signal increases, balancing pole look (for example red) extended upward linear array point-blank, and 710 to top 720 from the bottom.On the contrary, when the volume down of audio signal after a little while, equalizer bar color (for example red) 720 710 is extended downwards to the bottom point-blank from top, only stays background color (for example blue), it is lighted with extinguishing side by side of balancing pole color basically.
Selectively, weight scheme is applied to " graphic equalization demonstration " function, the tangible weight that acts on amplitude by this increases and reduces.For example, the microcontroller of configurable driving tube 700 to be to produce a kind of effect, the increase of balancing pole color response volume and moving up by this, and this moves than bar color and is moved downward to faster that the volume that reduces identical magnitude comes.Microcontroller allows volume to be increased in the long enough time by the balancing pole color from expression visually thus, can discover and holds this visual representation by observing balancing pole.Because the LED in the bar is actuated to substantially side by side change in response to volume, this guarantees the response audio signal that LED can be so not fast, produces flicker effect thus, forms the result who has more the joyful sense of vision in this way.
Though the present invention describes with reference to preferred embodiment, the skilled person will understand, and can change and the unlikely the spirit and scope of the present invention that depart from form and details.
