Description
Technical field
The present invention relates to illumination and the method for Intelligent housing field single fire line control illumination light modulation and switch.
Background technology
With the development of lighting field technology, the new product of lighting apparatus continues to bring out, simultaneously for the control of illuminating product
Method processed it is also proposed the requirement of renewal, and energy saving, intelligent wireless control illumination becomes the direction of Future Development.Existing comparison
The illumination light regulating technology of popularization mainly with the phase-cut dimming (also having referred to as chopper light modulation) of instantaneous trip Alternating Current Power Supply, that is, passes through
The method of some section of phase of instantaneous trip alternating current power supply achievees the purpose that to control brightness of illumination, before being divided into phase-cut dimming and
Phase-cut dimming afterwards.Light modulation of the method for resistive load (incandescent lamp) is highly effective, and light adjusting circuit is simple and reliable, cost
Cheap, popularity is wide；Due to only needing single firewire to connect, install and use very convenient, be current most popular dimming mode.
But the relatively new non-resistive load for occurring later, such as inductive load illumination (fluorescent lamp) and more novel appearance
Property load energy-saving light etc., due to containing nonlinear electronic circuit in lighting apparatus, cause the application of phase-cut dimmer
It is restricted.These illumination light modulation, it is necessary in the drive circuit of illumination design specialized light adjusting circuit, and need set up
Special brightness adjustment control end is controlled light modulator, at this time since dedicated electronic circuit needs to power, dedicated light modulation
Control terminal needs the problems such as in addition wiring so that the method that the light modulation of such illumination cannot continue to use phase-cut dimming merely.Originally can
In the method that brightness adjustment control is carried out by single firewire of simple realization, become extremely difficult and multiple after novel illumination has been used
It is miscellaneous, and cost is substantially increased compared with using silicon-controlled phase-cut dimmer, and the performance of light modulation also becomes excessively poor.Particularly
In recent years the popularization of LED illumination product, very excellent dimming behavior cannot play LED in itself, become energy-saving lighting and push away
Wide and popularization bottleneck.
By taking LED illumination as an example, the LED illumination being primarily present currently on the market dims product, substantially with compatible existing
Light modulator developed for thinking, its principle is using cut phase waveform caused by phase-cut dimmer light modulation, it is detected
After be converted to PWM dim signals and be controlled.AC power waveform is distorted during due to cut phase, can be produced serious electromagnetism and be done
Disturb；The state of power supply is highly unstable under cut phase power supply state, is needed particularly under small-power state during the silicon-controlled work of cut phase
There is a bigger maintenance electric current, can then produce glittering when controlled lighting current is less than the value, some products are
Avoid glittering, it is artificial to increase fictitious load to maintain the normal work of phase-cut dimmer.These factors result in shining for LED illumination
The problems such as efficiency declines, and needs to match between driver and phase-cut dimmer, and dimming scope is narrow and glitters, in order to solve this
A little problems add the auxiliary electron circuit of many again, the cost increase for causing LED illumination to dim, and make script excellent performance
LED illumination is severely limited in the application of adjustable optical arena.Correlation technique may be referred to CN02587532U, CN01827474A
Deng patent.
The present invention breaches the thinking for continuing to use existing light modulator, employs the side of active control switches on wall state-detection
Method, controls illumination driver, lighting apparatus and dimming loop can obtain surely by switch state for light modulation and switching signal
Fixed power supply, while single fire line control light modulation and switch (non-single live wire power getting pattern) can be realized again.Application should on this basis
Scheme can more realize the multiple spot brightness adjustment control that illumination brightness adjustment control can not be realized at present, breach traditional brightness adjustment control
Basic conception.
The content of the invention
The present invention is the principle that make use of the signal of different frequency that different impedances are presented when being transmitted on same line, is being supplied
Electricity control firewire on couple a upper frequency signal, by switch short or disconnect control whether to prevent this compared with
High-frequency signal reflects the virtual condition of switch, and is sent after being converted to control signal by electric circuit inspection to illumination driver
Control terminal to illumination carry out light modulation with switch control.
Two signals of height frequency share a control firewire, and are independent of each other, and are actually opened for brightness adjustment control
A dedicated frequency channel is warded off.
Fig. 1 is the principle of the present invention figure.By controlling switch (10), control terminal trap (11), load end trap (12),
Signal source generator (13), signal coupler (14), signal magnitude detector (15), control signal converter (16), power supply
(17), the compositions such as dimming driver (18), illumination (19), high pass low-cut filter (22), control firewire (21) are illuminated.Trap
Low pass high-cut filter can be used, it is desirable to low resistive state is presented to the 50HZ power frequencies of power supply, and is in another high-frequency signal
The high-impedance state now stopped.Alternating current 220V firewire is by control terminal trap (11), control firewire (21) and load end trap
(12) being connected directly between after ensures the normal power supply of electronic loop on illumination dimming driver (18) and power supply (17).Believe at this time
Number source generator (13) produces one and is far above the active detecting signal (F) of 50HZ work frequencies, and passes through signal coupler
(14) coupled on control firewire (21).And control terminal trap (11) and load end trap (12) then believe the active detecting
High-impedance state is presented in number (F).When controlling switch (10) disconnects, since active detecting signal (F) is closed in control terminal wave arrestment
Between device (11) and load end trap (12), the load condition of high resistant is presented, so being connected on signal coupler (14)
Signal magnitude detector (15) can detect the amplitude of higher active detecting signal (F)；When controlling switch (10) closes
Control terminal trap (11) short circuit is subjected to due to switching, so active detecting signal (F) is able to by controlling switch (10)
And firewire (L), and the high-pass filter (22) by being connected between firewire (L) and zero curve (N) is formed into a loop, and low-resistance is presented
Load condition, active detecting signal (F) will significantly be decayed, and signal magnitude detector (15) will detect that non-at this time
Often low signal amplitude, or even can't detect.Signal magnitude detector (15), which exports this variable signal to control signal, to be turned
Parallel operation (16), signal amplitude change and the length of duration of the converter by detection, is converted to illumination dimming driver
(18) dim signal and switching signal.Control signal realizes the control to illumination (19) by illuminating dimming driver (18).
The state of operation-control switch (10), it is this actively launch signal by way of detect signal amplitude, switch shape
State synchronous with detection signal amplitude in real time can almost change, and binary message, example can be transmitted using this synchronous change
Such as manual rotation encoder can be used to carry out increasingly complex control signal transmission.
The amplitude of the active detecting signal (F) used as light modulation and the change of amplitude duration, since control is opened
Clearly, this method is using directly detection signal transmission source end for the change of the two states impedance of pass (10) opening and closing
Amplitude, and the signal amplitude at signal transmission source end is under high resistance load environmental condition, even if signal source generator (13) is defeated
Go out interior anti-higher, under the low-down state of output power, can also obtain the high signal voltage amplitude of comparison.And in common electric power
Under thread environment, low-down state is nearly all presented in the impedance for active detecting signal (F), more by being connected to firewire
(L) and zero curve (N) end the high-pass filter (22) (or bandpass filter) for active detecting signal (F) frequency cause
The interference signal that same voltage amplitude is established in 220V AC powers is practically impossible to.And when controlling switch (10) closes
When, which is destroyed, and the output of signal source generator (13) causes to lead to since internal output impedance is higher
After crossing signal coupler (14), the voltage amplitude of signal is significantly decayed in signal magnitude detector (15).Its changing value holds very much
Easily detect and be not easily susceptible to the interference of other signals, detection mode is simple and reliable.
The signal that signal source generator (13) is sent is closed between two traps when controlling switch (10) disconnects,
It can select to be not easy the frequency (wavelength for being more than 4 times of command range length) to space radiation in command range length range.
Signal source generator (13) is operated in high-impedance state, with the internal resistance of promotion signal source it can be reduced output power, so both
After controlling switch (10) closure can be lifted, the amplitude of signal attenuation when high resistant environment resistant is destroyed so that signal amplitude detection
Device (15) is more prone to the change of discriminating state, while can suppress signal source again to exterior interference, it should be noted that signal
Source internal resistance cannot be lifted infinitely, it is necessary to be balanced with trap impedance.The similar MW receiver of signal source generator (13)
Local oscillator, can almost ignore to exterior interference.
It can be dimmed and be switched due to the use of the state of switch and the duration of state, can be directly using comparing
Simple Self-resetting contact switch is controlled.
This method, which completely avoid control circuit, needs single live wire power getting or the power supply of zero firewire and special light modulation of arranging
The requirement of control line, at the same can avoid again with after silicon-controlled phase-cut dimming circuit in series supply waveform distortion caused by it is various not
Sharp factor so that the performance of new Dimmable lighting is played completely.The mode of connection of single firewire has been continued to use in terms of wiring, has been made
New Dimmable lighting when having fitted up room and being replaced, can fully be sent out on the premise of without destroying finishing and increase wiring
Wave the excellent properties of illumination.
