Source.
Background technology
It is known that dual-colored LED light bar has more preferable decorative lighting effect, the LED that current double-colored light bar uses is double
Color full power, is all to use Dual Drive circuit realiration, and this causes the cost driving power supply slightly higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of more reasonable structure, production cost
Lower double power incremental type LED drive power.
In order to solve the technical problem of above-mentioned existence, this utility model employing following technical proposals:
A kind of double power incremental type LED drive power, controls including interconnective MCU chip, power module and output
Circuit, wherein:
Described power module includes IC1 and metal-oxide-semiconductor Q1；Described metal-oxide-semiconductor Q1 exports for double electric current, its G pole and MCU core
Sheet corresponding pin connects；

Pole pipe Q2, Q3；The base stage of described audion Q2, Q3 is connected with MCU chip corresponding pin respectively, with metal-oxide-semiconductor Q1 while of emitter stage
S pole connect after ground connection, colelctor electrode is connected with the G pole of controllable silicon SC1, SC2 respectively；The A pole of described controllable silicon SC1, SC2 is respectively
It is connected with the negative terminal of positive and negative lamp string LED1, LED2, for controlling forward and reverse energising of lamp string.
In the improvement project to above-mentioned pair of power incremental type LED drive power, the model of described MCU chip is
MK6A12P。
In the improvement project to above-mentioned pair of power incremental type LED drive power, the model of described IC1 is S5133D.
Compared with prior art, the beneficial effects of the utility model: only singly drive with due to power module and can be achieved with
Double power output of two cluster of lamps, ornamental strings, more reasonable structure the most of the present utility model, production cost are lower.
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
[accompanying drawing explanation]
Fig. 1 is the circuit block diagram of this utility model embodiment；
Fig. 2 is the circuit theory schematic diagram of this utility model embodiment.
[detailed description of the invention]
A kind of double power incremental type LED drive power, as shown in Figure 1, 2, including interconnective MCU chip 1, power supply mould
Block 2 and output control circuit 3, wherein:
Described power module 2 includes IC1 and metal-oxide-semiconductor Q1；Described metal-oxide-semiconductor Q1 exports for double electric current, i.e. during its conducting
Realizing increasing electric current (being called for short incremental), its G pole is connected with the corresponding pin of MCU chip 1；
Described output control circuit 3 includes controllable silicon SC1, SC2, controls respective controllable silicon SC1, SC2 break-make respectively
Audion Q2, Q3；The base stage of described audion Q2, Q3 is connected with MCU chip corresponding pin respectively, and emitter stage is simultaneously and metal-oxide-semiconductor
Ground connection after the S pole connection of Q1, colelctor electrode is connected with the G pole of controllable silicon SC1, SC2 respectively, when audion Q2 is not turned on, controlled
Silicon SC1 turns on；And when audion Q2 turns on, controllable silicon SC1 is not turned on；Equally, when audion Q3 is not turned on, controllable silicon
SC2 turns on；And when audion Q3 turns on, controllable silicon SC2 is not turned on；The A pole of described controllable silicon SC1, SC2 is respectively with positive and negative
The negative terminal of lamp string LED1, LED2 connects, for controlling forward and reverse energising of lamp string；The anode of described positive and negative lamp string LED1, LED2
It is connected with the corresponding pin of power module.
This utility model is so work:
When MCU chip 1 control audion Q2 be not turned on time, controllable silicon SC1 turn on, power module 2 exports electric current about
240MA, at this moment makes LED1 lamp gang up electricity and lights；And when MCU chip 1 control audion Q3 be not turned on time, controllable silicon SC2 turn on,
Power module 2 exports electric current about 240MA, and at this moment LED2 lamp is ganged up electricity and lighted, and thus achieves and drives single power of power supply defeated
Go out LED1, alternately the lighting of 2 lamp strings；
When MCU chip 1 control audion Q2, Q3 be all not turned on time, controllable silicon SC1, SC2 then simultaneously turn on, and then make MOS
Pipe Q1 turns on, and power module 2 exports double electric current and lights to LED1,2 lamp strings simultaneously, thus it is incremental to realize double power.
From the aforegoing it can be seen that power module of the present utility model only with a metal-oxide-semiconductor this singly drive can be achieved with forward and reverse
Double power output of the lamp string of input, more reasonable structure, production cost therefore are lower.
Specifically, described MCU chip 1(i.e. IC1) model can be MK6A12P etc..
The IC1 model of described power module 2 can be S5133D etc..
It is only this utility model preferred embodiment in sum, is not used for limiting practical range of the present utility model.
The most all equivalence changes made according to the content of this utility model claim and modification, all should belong to skill of the present utility model
Art category.
