The utility model is not used to limit the utility model.
One, the art of this patent scheme:
1, as shown in Figure 1 (removal driving circuit and negater circuit), including first selector, first selector three it is defeated
Tri- LED lamp of R, G, B, the 4th LED lamp, linker and the second selector that exit port is separately connected, in second selector
The control logic of any three output ports respectively corresponds the control logic for being synchronized with tri- lamps of ray machine R, G, B；When logic inputs
Signal is input to first selector and second selector simultaneously, and the linker will be any in four output ports of second selector
When a port is connected with the 4th lamp, the control of synchronous any one of tri- LED lamp of R, G, B of the control logic of the 4th LED lamp
Logic processed, or the control logic independently of tri- lamps of R, G, B.
Wherein, the control logic of synchronous any one of tri- LED lamp of R, G, B of the control logic of the 4th LED lamp, or it is independent
Following several situations are referred in the control logic of tri- lamps of R, G, B:
First output port in second selector, second output terminal mouth, third output port respectively corresponds and first choice
The control logic of three output ports of device corresponds to identical；It is assumed that logic input signal is divided into the first logical signal, the second logic
Signal, third logical signal and the 4th logical signal；Control logic is referred to for identical logic input signal, by right
The first selector or second selector answered will need the LED light being lit to be lit.
When setting logic input signal is the first logical signal, R lamp is lighted in first selector selection, and G, B lamp are not lighted；
When logic input signal is the second logical signal, G lamp is lighted in first selector selection, and R, B lamp are not lighted；
When logic input signal is third logical signal, B lamp is lighted in first selector selection, and R, G lamp are not lighted；
When logic input signal is four logical signal, first selector does not light R, G, B LED light；
1) if desired the 4th LED lamp is identical as R lamp control logic, i.e., is lit simultaneously, then linker is by the 4th LED
Lamp and the first output port of second selector are connected, the 4th LED lamp and second selector second output terminal mouth, third port with
And the 4th port be disconnect design；
2) if desired the 4th LED lamp is identical as G lamp control logic, i.e., is lit simultaneously, then linker is by the 4th Bp
Lamp and second selector second output terminal mouth are connected, the 4th LED lamp and the first output port of second selector, third port with
And the 4th port be disconnect design；
3) if desired the 4th LED lamp is identical as B lamp control logic, i.e., is lit simultaneously, then linker is by the 4th Bp
Lamp and second selector third output port are connected, the 4th LED lamp and the first output port of second selector, second port with
And the 4th port be disconnect design；
4) if desired the 4th LED lamp is different from the control logic of R, G, B lamp, i.e. the 4th LED lamp is not appointed with R, G, B lamp
Meaning one is lit simultaneously, then linker connects the 4th LED lamp and the 4th output port of second selector, the 4th LED
Lamp and the first output port of second selector, second port and third port are to disconnect design；
Wherein for example: the first logical signal, the second logical signal, third logical signal and the 4th logical signal are right respectively
It should be 00,01,10 and 11 or first logical signal, the second logical signal, third logical signal and the 4th logical signal point
01,10,11 and 00 is not corresponded to.
2, linker refers to resistance, jumper cap or conducting wire；
3, R, G, B lamp respectively represent red light, green light, blue lamp；4th LED lamp (Bp lamp) represents second blue lamp.
4, first selector is the voltage signal that input voltage is 9V to 24V and the current signal that electric current is 0.1A to 16A
Chip, first selector is the logic input signal that can receive Master control chip output, and the telecommunications of output driving R, G, B lamp
Number.
5, second selector is the selection logic selection chip at least possessing the output of four tunnels.
Two, when linker connects the second selector and the 4th LED lamp but the 4th LED lamp can not be driven to work
When, then driving circuit is set between linker and the 4th LED lamp.The driving circuit that example is added as shown in figure 1.
Wherein, driving circuit are as follows: TPS92641 LED drive circuit or other can drive the scheme of great power LED；
When the level logic of the second selector and the opposite level logic of first selector, exported in second selector
End setting negater circuit.The negater circuit that example is added as shown in figure 1.
Such as: as shown in figure 1, logic input signal is input to first selector simultaneously, controls R, G, B lamp and the second selection
Device, because therefore selection level logic and the logic selector level logic of first selector in selector rear end on the contrary, be added
Negater circuit increases driving capability while adjusting logic.The control signal of 4th LED lamp is finally given to the 4th LED
Lamp drive circuit drives the 4th LED lamp (Bp lamp).
Three, the first selector is that m selects selector all the way；Second selector is n choosing selector all the way, wherein m is greater than
Equal to 3；N is more than or equal to 4；Wherein the control logic of three road output ports and three tunnels of second selector are defeated for certain first selector
The control logic of exit port is identical.
Specific embodiment one:
(first selector and R, G, B lamp are not shown) as shown in Figure 2, including second selector U1, transistor circuit Q9
Reversed and the 4th LED lamp of driving, resistance R750, R751, R752, R753 etc.；U1 receives the output signal of ray machine, passes through A, B
Two signal pins, can gate, any one in tetra- PIN feet of Y0 ~ Y3；As LED_SEL_0, LED_SEL_1 be [0,
When 0], Y0 is opened, and Y1 is opened when being [0,1], and Y2 is opened when being [1,0], and Y3 is opened when being [1,1]；Pass through again
The triode circuit of Q9 reversely and enhances driving capability.LED_SEL_0, LED_SEL_1 signal connect first choice simultaneously
Device controls the R of ray machine indispensability, and tri- lamps of G, B, R lamp is bright when [0,0], and G lamp is bright when [0,1], and B lamp is bright when [1,0].
In the design application, it can be selected (in four resistance positions by R750, R751, R752, the piece uploading of R753
Any one position connects device, remaining position position disconnects design), realize the 4th LED lamp and routine R, G, B tri- of ray machine
Any one synchronization of lamp, can also individually control the closing of the 4th LED lamp.Such as: R752 piece uploading, corresponding control signal are
[1,0], as synchronous with B lamp, R753 piece uploading, corresponding control signal are [0,0], as the 4th LED lamp independent control.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
