Description
Technical field
The present invention relates to a kind of LED drive device of LED daylight lamp field, particularly relate to the comprehensive complete compatible drive unit of a kind of low cost.
Background technology
There is no announced complete compatible fluorescent lamp drive scheme in the world, the known ET (electronic transformer) or the IT (inductive transformer) that only have compatible a certain type, and known compatible lines complexity very, cost is high, size is very large.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, one is provided neither to damage fluorescent tube, the compatible compatibility both having realized four types such as inductance type, couple electronic formula, ordinary electronic formula, preheating electronic type and the complete compatible drive unit directly inputted civil power when also not damaging ballast.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is: the comprehensive complete compatible drive unit of low cost, comprises intelligent control unit, current limit constant current unit, high-frequency constant current control IC, voltage monitoring unit, LED string, resistance R, diode D1, diode D2, diode D3, diode D4, diode D5, diode D6, diode D7, diode D8, diode D9, inductance L, electric capacity C, K switch 101, K switch 102, K switch 103, first inputs contact A, the second input contact B, the 3rd input contact C and the 4th input contact D; K switch 101, LED string, inductance L, K switch 103 and resistance R connect successively; Diode D1 anode is electrically connected with the first input point A, and negative electrode is electrically connected with K switch 101; Diode D2 anode is electrically connected with the second input point B, and negative electrode is electrically connected with K switch 101; Diode D3 negative electrode is electrically connected with the first input point A, and anode is electrically connected with resistance R; Diode D4 negative electrode is electrically connected with the second input point B, and anode is electrically connected with resistance R; Diode D5 anode is electrically connected with the 3rd input point C, and negative electrode is electrically connected with K switch 101; Diode D6 anode is electrically connected with the 4th input point D, and negative electrode is electrically connected with K switch 101; Diode D7 negative electrode is electrically connected with the 3rd input point C, and anode is electrically connected with resistance R; Diode D8 negative electrode is electrically connected with the 4th input point D, and anode is electrically connected with resistance R; Electric capacity C and LED connection in series-parallel, K switch 102 is in parallel with inductance L, and diode D9 is connected in parallel on K switch 101, between LED string and inductance L; Voltage monitoring unit: the magnitude of voltage detected also is flowed to high-frequency constant current control IC by terminal voltage on sense switch K103; High-frequency constant current control IC: judge whether to make K103 enter high frequency BUCK PWM or enter current limliting operational mode with the current value of the K switch 103 detected according to the magnitude of voltage that voltage monitoring unit exports; Current limit constant current unit: for being entered the pattern of current limliting constant current by K switch 103, to prevent electric current excessive by the peak current of monitoring resistor R; Intelligent control unit: the signal provided by electric current and current limit constant current unit on voltage monitoring unit, resistance R realizes the sequencing control to K101 by delta time delay method.
As further improved technical scheme of the present invention, described LED string comprises at least two LED component, and described LED component is single LED lamp pearl or LED string or LED strip and combines.
Whether when the present invention starts, K101 is open-minded, and K102 turns off, and K103 opens and current-limit mode is opened, be utility mode by terminal voltage on monitoring K103; If utility mode, then keep the state of K101 and K102, start high frequency and control to make K103 enter BUCK PWM operational mode; If not utility mode, then keeping the state of K101 and K103, open K102, is also short circuited inductance, by detecting main line current monitoring starting state; If do not started, then by turning off K101, then delay a period of time opens K101 again to realize delayed trigger.Specifically, the present invention can realize two kinds of judgements: be first judge whether civil power, then determining the end is electric ballast or Inductive ballast, judge here according to respectively:
First, the judgement of civil power is to the detection of the voltage of K103 upper end and judgement by voltage monitoring unit, when voltage on K103 is higher than a certain value, voltage monitoring unit just thinks that civil power has been come in, thus will judge that Signal transmissions is to high-frequency constant current control IC, this IC enters rapidly high frequency control K103, thus enters high frequency voltage descending control; In addition, when whether initial decision is civil power, pour in destruction components and parts in order to what prevent civil power, first K103 is the pattern being entered a kind of current limliting constant current by current limit constant current unit, prevents electric current excessive.
So second pair of electric ballast or Inductive ballast, carry out Based Intelligent Control K101 by the detection of the voltage for electric current on resistance bottom and voltage monitoring unit, because originally K101 is conducting, if this time, resistance below still do not have electric current, and magnitude of voltage on K103 is not high yet, illustrate it is not civil power, so, K101 will close by intelligent control unit, again K101 is opened after postponing a bit of time, if still cisco unity malfunction, then progressively will lengthen time of delay, until system worked well, this method can be called delta time delay method.
Input point A in the present invention, B, C and D are four input endpoints that can access arbitrarily, and current limit constant current unit is one and monitors and control the unit of peak current; High-frequency constant current control IC is a high frequency voltage descending current constant control chip; Voltage monitoring unit is to the detection of terminal voltage on K103; Intelligent control unit is one and realizes the intelligent control unit of sequential and pattern by signal monitoring.The present invention adopts intelligent decision and compensation to realize civil power and Inductive ballast/electric ballast is entirely compatible; Be utilize external inductors automatically to realize constant current when electronics and Inductive ballast pattern, and there is Current limited Control; Realize constant current by high-frequency PWM pattern during utility mode; And LED is directly as load, does not adopt Capacitor apart; The needs to different ET/IT are controlled by time delay process; According to the voltage of monitoring, current signal to input state intelligent decision.The present invention can realize pluggable, any electric ballast of any direction can compatible, arbitrarily Inductive ballast can compatible, civil power can compatible, arbitrarily pluggable (containing hot plug), by UL leakage tests.In a word, the present invention neither can damage fluorescent tube, the compatible compatibility both having realized four types such as inductance type, couple electronic formula, ordinary electronic formula, preheating electronic type and the full compatibility directly inputted civil power when also not damaging ballast.
