Description
Technical field
The present invention relates to lamp decoration field, refers in particular to the driving power for driving the double-colored lamp strings of LED or light bar to work.
Background technology
It is known that dual-colored LED lamp band has a more preferable decorative lighting effect, the LED used on current bi-colour light band is double
Color full power, all it is to use dual drive circuit realiration, this causes the cost of driving power slightly higher.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of more reasonable structure, production cost are lower
Double power flow increasing type LED drive powers.
In order to solve above-mentioned technical problem, the present invention uses following technical proposals：
A kind of double power flow increasing type LED drive powers, including the MCU chip of interconnection, power module and output control
Circuit, wherein：
The power module includes IC1 and metal-oxide-semiconductor Q1；The metal-oxide-semiconductor Q1 exports for double electric current, its G pole and MCU core
Piece corresponding pin connects；
The output control circuit includes controllable silicon SC1, SC2, controls the three of respective controllable silicon SC1, SC2 break-make respectively
Pole pipe Q2, Q3；Described triode Q2, Q3 base stage are connected with MCU chip corresponding pin respectively, emitter stage simultaneously with metal-oxide-semiconductor Q1
S poles connection after be grounded, colelctor electrode is connected with controllable silicon SC1, SC2 G poles respectively；Described controllable silicon SC1, SC2 A poles difference
It is connected with the negative terminal of positive and negative lamp string LED1, LED2, for controlling forward and reverse energization of lamp string.
In the improvement project to above-mentioned double power flow increasing type LED drive powers, the model of the MCU chip is
MK6A12P。
In the improvement project to above-mentioned double power flow increasing type LED drive powers, the model of the IC1 is S5133D.
Compared with prior art, beneficial effects of the present invention：Because power module only can be achieved with two strings with single drives
Double power outputs of lamp string, therefore the more reasonable structure of the present invention, production cost are lower.
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
【Brief description of the drawings】
Fig. 1 is the circuit block diagram of the embodiment of the present invention；
Fig. 2 is the circuit theory schematic diagram of the embodiment of the present invention.
【Embodiment】
A kind of double power flow increasing type LED drive powers, as shown in Figure 1, 2, including the MCU chip 1 of interconnection, power supply mould
Block 2 and output control circuit 3, wherein：
The power module 2 includes IC1 and metal-oxide-semiconductor Q1；The metal-oxide-semiconductor Q1 exports for double electric current, i.e., when it is turned on
Realize increase electric current（Abbreviation flow increasing）, its G pole is connected with the corresponding pin of MCU chip 1；
The output control circuit 3 includes controllable silicon SC1, SC2, controls respective controllable silicon SC1, SC2 break-make respectively
Triode Q2, Q3；Described triode Q2, Q3 base stage are connected with MCU chip corresponding pin respectively, emitter stage while and metal-oxide-semiconductor
It is grounded after Q1 S poles connection, colelctor electrode is connected with controllable silicon SC1, SC2 G poles respectively, controllable when triode Q2 is not turned on
Silicon SC1 is turned on；And when triode Q2 is turned on, controllable silicon SC1 is not turned on；Equally, when triode Q3 is not turned on, controllable silicon
SC2 is turned on；And when triode Q3 is turned on, controllable silicon SC2 is not turned on；Described controllable silicon SC1, SC2 A poles respectively with it is positive and negative
The negative terminal connection of lamp string LED1, LED2, for controlling forward and reverse energization of lamp string；The anode of positive and negative lamp string LED1, LED2
It is connected with the corresponding pin of power module.
The present invention so works：
When MCU chip 1 controls triode Q2 to be not turned on, controllable silicon SC1 conductings, the output current of power module 2 is about
240MA, LED1 lamp strings is powered and light；And when MCU chip 1 controls triode Q3 to be not turned on, controllable silicon SC2 conductings,
The output current about 240MA of power module 2, at this moment LED2 lamp strings energization are lighted, and are so achieved that single power of driving power is defeated
Going out --- LED1, the alternating of 2 lamp strings are lighted；
When MCU chip 1 controls triode Q2, Q3 to be all not turned on, controllable silicon SC1, SC2 are then simultaneously turned on, and then make MOS
Pipe Q1 is turned on, and power module 2 exports double electric current to LED1,2 lamp strings while lighted, so as to realize double power flow increasings.
From the aforegoing it can be seen that only with a metal-oxide-semiconductor, this list drive can be achieved with forward and reverse input to the power module of the present invention
Lamp string double power outputs, therefore more reasonable structure, production cost it is lower.
Specifically, the MCU chip 1（That is IC1）Model can be MK6A12P etc..
The IC1 models of the power module 2 can be S5133D etc..
It is only preferred embodiments of the present invention in summary, is not used for limiting the practical range of the present invention.That is Fan Yiben
The equivalence changes and modification that the content of patent application the scope of the claims is made, it should all belong to the technology category of the present invention.
