Please refer to Fig. 1, this driving chip IC1 is provided with DIM pin, Vs pin, COM1 pin, and this radio receiving transmitting module 40 is provided with DIM pin, Vcc pin and on/off pin.DIM pin on this radio receiving transmitting module 40 is for connecting with the DIM pin on this driving chip IC1.The exportable dim signal of DIM pin of this radio receiving transmitting module 40 gives this driving chip IC1 electric current exported to LED light source 60 to change secondary winding, thus controls the secretly bright of this LED light source 60, realizes the function of light modulation.This Vcc pin is for controlling the voltage of this first auxiliary winding (2,3).
On/off pin on this radio receiving transmitting module 40 is connected with this driving chip IC1 by this signal analyse block 30.This signal analyse block 30 comprises the first triode Q2, a second triode Q3 and two diode D5 in parallel.This on/off pin is connected with the base stage of this first triode Q2, and the emitter of this first triode Q2 is connected to the base stage of this second triode Q3.The collector electrode of this first triode Q2 is connected to the Vcc pin of this radio receiving transmitting module 40 by voltage-stabiliser tube ZD1.The collector electrode of this second triode Q3 is connected to the negative pole of these two diode D5 in parallel, on the Vs pin that the positive pole of this parallel diode D5 is connected respectively to this driving chip IC1 and COM1 pin.This radio receiving transmitting module 40, by being connected with RF antenna 50, is received and dispatched the wireless control signal that user sends.
The specific works flow process of this LED intelligent wireless drive circuit is introduced below in conjunction with Fig. 1 and Fig. 2.This rectification filtering module 10 connects civil power, and alternating current is converted to direct current.The driving chip IC1 of this LED isolation drive module 20 is directly started with high voltage direct current by this rectification filtering module 10.The Partial DC electricity that this rectification filtering module 10 exports directly transports to this transformer T1 elementary (4,5) 4 ends, this transformer T1 elementary (4,5) 5 ends are connected to switch mosfet Q1, control with square wave the HF switch that switch mosfet Q1 carries out about 50KHz after this driving chip IC1 starts, make this transformer T1 elementary (4,5) high frequency alternating current is produced in, thus can power to this LED light source 60 with electromagnetic energy conversion between this transformer T1 level (A, B); The wireless signal received is converted to level controling signal (TTL signal) by this radio receiving transmitting module 40, this level controling signal feeds back to this signal analyse block 30, by this signal analyse block 30, the level controling signal received is converted to the analog signal controlling this driving chip IC1 again, this driving chip IC1 adjusts this transformer T1 level (A according to this analog signal, B) output voltage or output current, to open and close this LED light source 60 or to regulate its brightness.
In this Wireless Light modulating drive circuit, its specific works principle controlling LED light source 60 by radio receiving transmitting module 40 is: when the on/off pin of this radio receiving transmitting module 40 is in high level on state, this first triode Q2, the second triode Q3 and parallel diode D5 are all switched on, and the Vs pin on this driving chip, the voltage of COM1 pin are dragged down accordingly.Meanwhile, the collector electrode of this first triode Q2 by the voltage clamp of this Vcc pin at low-pressure state.Because the voltage of the first auxiliary winding (2,3) is determined by Vcc, it is also in low-pressure state simultaneously, and this just makes secondary winding be in low-pressure state.When the voltage of the voltage on this secondary winding lower than this LED light source, the just not conducting of this LED light source 60.The voltage dragged down on Vs can reduce the frequency of oscillation of this driving chip IC1, to reduce stand-by power consumption.Drag down voltage and power that COM1 then reduces T1 the level output of this transformer, make this LED light source 60 not luminous.Otherwise, if the on/off pin output low level of this radio receiving transmitting module 40, then can draw high the level of Vs pin on this driving chip IC1 and COM1 pin, therefore improve the output voltage of this transformer T1 level, make this output voltage reach the starting resistor of this LED light source 60, this LED light source 60 is just luminous.
The effect of this second triode Q3 is to improve the level exported from the first triode Q2 further, guarantees that this two parallel diode D5 is switched on or close.Certainly, when rate is enough good respectively for the level signal that the first triode Q2 exports, this second triode Q3 also can not be set.
In sum, because this LED intelligent wireless drive circuit is provided with the first auxiliary winding (2 on this armature winding, 3), this first auxiliary winding is utilized to power to this radio receiving transmitting module 40, and this first auxiliary winding (2,3) number of turn on is adjustable, makes this radio receiving transmitting module 40 can obtain the suitable voltage and current of size, can not cause the power wastage of holding state because of the keying of this LED light source 60.Thus make this LED intelligent wireless drive circuit have the higher advantage of whole efficiency.Adopt this LED intelligent wireless drive circuit that whole efficiency can be made to be promoted to more than 85% from about 70%, complete machine stand-by power consumption is less than 0.5W, meets the requirement of up-to-date America and Europe about the standard of stand-by power consumption.In addition, this main drive IC 1 is powered by this second auxiliary winding (1,3) and also can be promoted whole efficiency.The signal that this radio receiving transmitting module can be sent by arranging this signal analyse block 30 is effectively changed and is exported to this driving chip IC1, makes this radio receiving transmitting module 40 can control Vs pin and the COM1 pin of this driving chip IC1.The frequency of oscillation of this driving chip IC1 can be reduced, to reduce stand-by power consumption by the voltage dragged down on Vs.
