Need the ginseng it is further noted that electronic circuit components and parts involved in above-mentioned each functional unit or module
Number, function, structure and operation principle etc. are all the technology known by those skilled in the art, and here will not be described in great detail.
The power supply 10 can be direct current after the conversion such as civil power, generating set etc., its as needed setting, at this
In embodiment, as the LED lamp group 13 is LED, so dc source of the power supply 10 for 24V.
The LED lamp group 13 includes the first contrary LED light group D1-Dn of least one set conducting voltage, and the second LED
Group Dn+1-D2n.First LED light group D1-Dn is arranged in parallel with second LED light group Dn+1-D2n.Many to it is well known that
A kind of light-emitting component of the LED for light emitting diode, i.e. one-way conduction, therefore when first LED light group D1-Dn and second
The conducting voltage of LED light group Dn+1-D2n in opposite direction when, when at a time for the LED lamp group 13 load one party
To voltage when, then a group in only described first, second LED light group can turn on luminous, and another group is turned off and does not light.
In the present embodiment, the LED lamp group 13 only includes two groups of LEDs, it is contemplated that the LED lamp group can be wrapped
Include multigroup, as long as it is reverse with the conducting voltage of other groups to have the conducting voltage of one group of LED.In order to reach colour temperature
Regulation and control, the colour temperature of first, second LED light group can be with difference, and such as one group colour temperature is the warm colour light of 2700K, and another group
Cool colour light of the colour temperature for 6500K.Certainly, their colour temperature can also be identical, but other parameters are different, such as light direction etc.,
It is set as desired.In order that the electric current being loaded in first, second lamp group D1-Dn, Dn+1-D2n meets its current ratings
Requirement, each group of LED light group can also be connected a current-limiting resistance respectively.In the present embodiment, the first, second lamp group
D1-Dn, Dn+1-D2n are connected resistance R7, a R8 respectively.
Described signal generator module 12A, 12B are respectively used to provide control for described two signal control modules 11A, 11B
Signal.It can be user's control that described signal generator module 12A, 12B can be single-chip microcomputer, timer or central processing unit etc.
Signal generation mechanism.In the present embodiment, described signal generator module 12A, 12B are single-chip microcomputer, and which is a kind of integrated circuit
Chip, its adopt very large scale integration technology the processor with data-handling capacity, random access memory, read-only storage
Device, multiple I/O mouths and interrupt system, the function such as timer and (may also include display driver circuit, pulse-width modulation circuit, simulation
The circuits such as multiplexer, A/D converter) it is integrated on one piece of silicon chip.Therefore, it can produce the signal according to actual conditions
Module 12A, 12B is programmed the programs such as control, such as system initialization, output level height, dutycycle.In the present embodiment,
Described signal generator module 12A, 12B export high level signal, or low level signal respectively according to the instruction or input of user, i.e.,
When signal generator module 12A exports high level signal according to the instruction of user, then signal generator module 12B then exports low level
Signal.Meanwhile, when high level signal is exported, first LED light group D1-Dn will be turned on and be lighted, and due to the second LED light group
Due to being reversely electrically connected with the first LED light group D1-Dn, therefore the second LED light group Dn+1-D2n will be cut off Dn+1-D2n.?
Therefore, user can by control the output of described signal generator module 12A, 12B come control the first LED light group D1-Dn with
The break-make of the second LED light group Dn+1-D2n, so that control the colour temperature of whole LED lamp group 13.It is understood, however, that the letter
Number generation module 12A, 12B can also pass through procedure auto-control.
Described two signal control modules 11A, 11B are respectively used to controlled loading to the electricity at 13 two ends of LED lamp group
The voltage direction of pressure, to control the break-make of first, second LED light group D1-Dn, Dn+1-D2n.Each signal control described
Molding block 11A, 11B include a PNP triode and a NPN triode.The PNP triode is arranged on the LED lamp
The high level end of regulator control system 100, and NPN triode is arranged on the low level end of the LED lamp regulator control system 100, and institute
State PNP triode, LED lamp group 13, NPN triode to be sequentially connected in series.Fig. 3 is refer to, the signal control module 11A bag
PNP triode Q1, and NPN triode Q4 is included, and signal control module 11B includes PNP triode Q2, and one
Individual NPN triode Q3, as PNP triode Q1, Q2, and the method for attachment of NPN triode Q3, Q4 should be this area skill
ABC known by art personnel, will not be described in detail herein.Referring to the circuit theory diagrams shown in Fig. 3, the LED is described
The operation principle of light fixture regulator control system 100.When the output signal of signal generator module 12A is high level, due to NPN triode
The characteristic of Q3, NPN triode Q3 will be turned on, and turn on PNP triode Q2 then, the output of synchronous signal generation module 12B
Signal is low level, then NPN triode Q4 will be closed, and PNP triode Q1 is closed then.Therefore, now the first LED light group
The two ends of D1-Dn are forward voltage, so that the conducting of the first LED light group D1-Dn, and the second LED light group Dn+1-D2n is closed.
And the output signal for working as signal generator module 12A is low level, when the output signal of signal generator module 12B is high level, electricity
The direction of pressure will switch over, i.e., the two ends of the second LED light group Dn+1-D2n are backward voltage, so that the first LED light group
D1-Dn is closed, and the conducting of the second LED light group Dn+1-D2n, and then realize that first, second LED light group D1-Dn, Dn+1-D2n exists
Switch between light on and off, so as to realize the regulation and control of light fixture colour temperature.It is understood that due to above-mentioned PNP triode, tri- poles of NPN
Pipe is used as a kind of switch, and which can also reach above-mentioned purpose using P-MOS pipes, N-MOS pipes, i.e., above-mentioned is all
PNP triode is replaced with P-MOS pipes, and NPN triode is replaced with N-MOS pipes, and its operation principle and effect are just as
's.
Compared with prior art, the LED lamp group 13 of the LED lamp regulator control system 100 by two groups in parallel first, the
The conducting voltage direction of two LED light groups is reverse, so as to the control signal for utilizing described signal generator module 12A, 12B to be exported,
And compiling of signal control module 11A, 11B to the control signal, and then can cause only just can be realized with two wires
The light on and off switching of first, second LED light group, it is achieved that the reduction of connecting wire, advantageously reduces cost and typesetting difficulty,
And reduce the structure of light fixture.
Presently preferred embodiments of the present invention is the foregoing is only, not in order to limit the present invention, all in essence of the invention
Interior made any modification of god and principle, equivalent and improvement etc., should be included in the interior of protection scope of the present invention.
