Fig. 5 is an application schematic diagram of the control system of the light-emitting component of one embodiment of the invention.The present invention does not limit
The application field of control system of the invention.Any need provides the electronic device of lighting effects, and control of the invention can be used
System processed.In a possible embodiment, control system 100 is applied in a host system 500.As shown, host system 500
With multiple display cards, such as 510 and 530, and the bridge 520 being coupled between display card.In the present embodiment, host system
System 500 supports multiple display card technique, such as SLI (Scalable Link Interface: scalable connecting interface).
Display card 510 has mixer 511, to AC-battery power source ingredient and signal component.Due to moving for mixer 511
Make the mixer 110 of similar 1st figure of principle, so it will not be repeated.In the present embodiment, due to 511 AC-battery power source ingredient of mixer
And signal component, therefore show that card 510 only needs that mixed result can be exported using single pin.
Bridge 520 is to couple multiple display cards.In the present embodiment, bridge 520 has separator 521, control
Device 522, light-emitting component 523 and 524.The present invention does not limit the quantity of light-emitting component.In other embodiments, bridge 520
Light-emitting component with other quantity.By the luminance of light-emitting component 523 and 524, the beauty of bridge 520 can be increased.
Separator 521 isolates power supply ingredient and signal component from the mixed signal that display card 510 is exported, and will
Result after separation is supplied to controller 522.Operation power of the power supply ingredient as controller 522.Controller 522 is according to signal
Ingredient generates corresponding control signal, to control luminescent color and the light on and off time of light-emitting component 523 and 524.
In other embodiments, display card 510 has mixer 511, but bridge 520 does not have separator 521, only has
There are controller 522 and light-emitting component 523,524.In this instance, controller 522 directly receives the mixed signal of mixer 511.By
There is flip-flop in the mixed signal of mixer 511, therefore still can normally drive control device 522.In this instance, controller
522 control light-emitting component 523 and 524 according to the pre-set programs stored by itself.
In another possible embodiment, display card 510 may not have mixer, but bridge 520 has separator
521, controller 522, light-emitting component 523 and 524.In this instance, display card 510 still only passes through single pin out-put supply ingredient
To bridge 520, with drive control device 520.In this instance, controller 522 controls hair according to the pre-set programs stored by itself
Optical element 523 and 524.
In some embodiments, display card 510 does not have mixer, and bridge 520 does not have separator 521.Though
Right bridge 520 only has controller 522 and a light-emitting component 523 and 524, but because display block 510 still transmit power supply ingredient to
Bridge 520, therefore, controller 522 can be acted according to power supply ingredient.In this instance, controller 522 is according to stored by itself
Pre-set programs control light-emitting component 523 and 524.
Using the control system of previous embodiment, although what is transmitted on cable is the mixing of power supply ingredient and signal component
Signal, but because supply voltage is constant, can equally be transmitted to the mixed signal in traditional equipment (such as SLI bridge joint card)
Light-emitting component, to light the light-emitting component in traditional equipment, i.e. the control system of the embodiment of the present invention can be with compatible traditional equipment.
Furthermore the control system of the light-emitting component based on above embodiments, one embodiment of the invention also provide a kind of member that shines
