Description
Technical field
The present invention relates to a kind of inductive lightning light fixture and a kind of inductive lightning system employing this inductive lightning light fixture, be specifically related to a kind of the inductive lightning light fixture and the inductive lightning system that have normal lighting function and function of emergency illumination concurrently.
Background technology
The effect of emergency lighting is when running into the disaster such as fire, earthquake for fire-fighting and rescue work provide illumination, thus ensures the life security of personnel in building.Particularly for skyscraper increasing in city now, once there is disaster, the difficulty of its fire-fighting and rescue work is very large, to the lighting quality of illuminator and stability requirement high especially.
But emergency luminaire on the market and emergency lighting system, all not fully up to expectations in lighting quality, stability and maintenance cost etc. at present.
And the key reason producing various weak point is: what normal lighting and emergency lighting adopted is two overlaps independently system, has independently light source separately; Or the light source in two cover systems is installed together, it seems that appearance be the same lamp tool, but inside still comprises 2 independent light sources.Wherein, normal lighting system adopts high-power (40 ~ 60 watts, even higher) light fixture as light source usually, and this is to ensure brightness of illumination and adapt to alternating voltage, reducing costs simultaneously; Emergency lighting then must adopt comparatively energy-conservation small-power (about 5 ~ 20 watts) light source, otherwise cannot provide power supply supply enough for a long time as the battery of stand-by power supply.
Two shortcomings of overlapping independently system normal lighting and emergency lighting are divided into be mainly manifested in following several respects:
1, outside normal lighting system, additionally a set of emergency lighting system is installed again, will inevitably installation cost be increased.And emergency lighting system must carry out periodic detection, light source and battery also will be changed according to service life in time, and maintenance cost is very high.Even if regular on request, emergency lighting system is safeguarded, but due to its utilization rate low, also cannot Timeliness coverage even if there is light fixture to damage, there is potential safety hazard all the time.In addition, many builders respond with idea of leaving things to chance, only pursue lightweight at a low price, and ignore regular maintenance, the very easily generation accident when disaster occurs.
2, when switching to emergency lighting from normal lighting, can there is unexpected change in brightness of illumination, easily raise fear.The light-source brightness of emergency lighting is lower, is only 5% ~ 10% of normal lighting, and is usually located at the places such as staircase, turning, edge, corridor, and density of setting is much smaller than normal lighting.Particularly focus in artistry and building attractive in appearance at some, the light source position of emergency lighting will be more hidden.After there is disaster power-off, in building, a slice is dim, and only have corridor and staircase to appear faint light, people inevitably pour into light source position in a large number, easily occurs chaotic and tramples accident.
3, normal lighting and emergence lighting lamp all do not support Width funtion, and voltage pulsation amplitude is slightly large, just cannot light.According to security against fire standard, when the voltage of civil power is just considered as power-off lower than during 187V, must emergency power supply be enabled, and the startup of emergency power supply must be completed before voltage is down to 132V.So, in this voltage range of 187V ~ 132V, if switch not prompt enough, then probably occur that normal lighting system is extinguished due to undertension, and emergency lighting system does not also have enough time the phenomenon that starts, being referred to as illumination disconnects, and has a strong impact on safety.
4, conventional emergence lighting lamp and the life of storage battery all shorter, regular maintenance needs frequent replacing, and cost is higher.Such as, the light source of the emergency lighting quartz lamp of usually selecting the life-span lower or Halogen lamp LED; The nickel-cadmium cell even lead-acid accumulator of low performance then selected by battery.Although hydrogen battery long service life, its power reservoir capacity, not as traditional battery, cannot ensure long-time power supply, cannot be applied in emergency lighting system.

Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.Should be understood that following examples only for illustration of the present invention but not for limiting scope of the present invention.
Embodiment 1:
Accompanying drawing 1 is the module map of the inductive lightning light fixture 10 of the embodiment of the present invention 1.
As shown in Figure 1, inductive lightning light fixture 10 is made up of light source portion 11, power control module 37, induction control module 20, state setting module 30, switch module 40 and battery 50.
Wherein, what light source portion 11 adopted is low power LED 13.Normal power source 12 is the civil power of AC220V.
Power control module 37 is connected with civil power and battery 50 simultaneously, and possesses decision circuitry 31, ac-dc converter circuit 35 and charge-discharge protection circuit 34.Under normal lighting pattern, power control module 37 accepts the power supply of civil power, and civil power is converted to the low-voltage DC of 12V by an ac-dc converter circuit 35 thus powers to induction control module and light source portion 11, charges to battery 50 simultaneously.When decision circuitry detects under the voltage drop of civil power to certain critical value preset, be just judged as civil power power-off, make inductive lightning light fixture 10 proceed to emergency lighting pattern, power control module 37 automatically switches to the power supply accepting battery 50.The effect of charge-discharge protection circuit 34 is when battery 50 charging and discharging, prevents from respectively overcharging and crossing putting, thus protection battery 50, extend its service life.
Induction control module 20 is made up of DC voltage converting circuit 27, sensor circuit 24 and light-operated circuit 26, and its effect is under normal lighting pattern, generates induced signal, and this induced signal is sent to switch module 40 by induction outer signals.The 12V voltage transitions transported from power control module 37 is become to be suitable for the 5V voltage that sensor circuit 24 and light-operated circuit 26 use by DC voltage converting circuit 27.Sensor circuit 24 for by responding to extraneous infrared signal to have judged whether pedestrian's process, and generates induced signal accordingly.Light-operated circuit 26 is for responding to extraneous light intensity, if extraneous light intensity is more weak, then allow sensor circuit 24 that the induced signal of generation is sent to switch module, otherwise then no matter whether sensor circuit 24 has sensed infrared signal, does not export induced signal.Simple employing infrared induction can realize only having pedestrian through out-of-date ability bright light, thus saves electric energy; And infrared induction is combined with light-operated, then can lighting-off by day automatically, energy-conservation further.What the sensor circuit 24 in the present embodiment adopted is infrared sensor, also can be replaced sonic transducer etc.
The effect of state setting module 30 is under emergency lighting pattern, sends a lasting setting signal to switch module 40.

As shown in Figure 2, first, the decision circuitry 31 in power control module 37 detects the voltage of civil power, judges whether it is greater than 187V (step 1).
If line voltage is greater than 187V, then ac-dc converter circuit 35 accepts the electric power of civil power, the civil power of AC220V is converted to the low-voltage DC (step 2) of 12V, and this low-voltage DC is exported to induction module 20, switch module 40 and power supply unit 11 (step 3).
Induction module 20 responds to whether there is outer signals (step 4).
If sense outer signals, induction module 20 generates an induced signal, and this induced signal is sent to switch module 40 (step 5), switch module 40 receives this induced signal and conducting (step 6), thus making light source portion 11 luminescence (step 7), workflow terminates.
If induction module 20 does not sense outer signals, then attonity, workflow terminates.
On the other hand, if in step 1, decision circuitry 31 detects that line voltage is less than 187V, then power control module 37 switches to battery 50 to power (step 8), and the low-voltage direct electric power provided by battery 50 directly exports to state setting module 30, switch module 40 and power supply unit 11 (step 9).
State setting module, after receiving the electric power that battery 50 provides, can generate a setting signal (step 10), and this setting signal is sent to switch module 40 (step 11) constantly.
Switch module 40 receives conducting (step 12) after this induced signal, thus makes light source portion 11 continuous illumination (step 13), and workflow terminates.
Embodiment 2:
Accompanying drawing 3 is the circuit diagram of the inductive lightning system 60 of the embodiment of the present invention 2.Accompanying drawing 4-5 is the circuit diagram of an inductive lightning light fixture 10 in the inductive lightning system 60 of embodiment 2.Below with reference to accompanying drawing 3-5, the workflow of inductive lightning system 60 is described in detail.
As shown in Figure 3, identical with embodiment 1, every inductive lightning light fixture 10 in embodiment 2 comprises light source portion 11, power control module 37, induction control module 20, state setting module 30, switch module 40 and battery 50, and the 26S Proteasome Structure and Function of these parts is also substantially the same manner as Example 1.Many such inductive lightning light fixtures 10 are parallel with one another shares one group of power supply, namely constitutes inductive lightning system 60.
And embodiment 2 and the difference of embodiment 1 are, inductive lightning system 60 also comprises the generator 52 that can be served as emergency power supply.This generator 52 is held by L and N ' end is connected with power control module 37, is generally intracardiac in the fire-fighting being arranged on building.
Under normal lighting pattern, generator 52 does not work, and N ' holds power-off, and power control module 37 is subject to civil power through N, L termination.Once decision circuitry 31 judges civil power power-off, then power control module 37 first by automatic switchover for be powered by battery 50, then, staff's manual unlocking generator 52 at fire-fighting center, there is provided from N ' end and answer urgent telegram, so power control module 37 is from being switched to by storage battery power supply through N ' and L end by answering urgent telegram to power.Meanwhile, hold the state setting module 30 be connected to detect with N ' and L and answer urgent telegram, send a lasting setting signal to switch module 40, make power supply minister bright.
Accompanying drawing 4 is the power control module 37 of inductive lightning light fixture 10 and the circuit diagram of battery 50, and accompanying drawing 5 is the circuit diagram of the over-discharge protection circuit 33 of battery 50.
First, under normal lighting pattern, the circuit theory shown in accompanying drawing 4 is described.
As shown in Figure 4, the civil power of AC220V enters rectifier bridge through N, L end, then after bulky capacitor C2 filtering, enters the decision circuitry 31 be made up of resistance R2, resistance R3, resistance R4, resistance R5, electric capacity C3, triode Q1, triode Q2.This decision circuitry 31 to be sampled civil power by resistance R2, resistance R3, resistance R4, if the voltage of civil power is higher than critical value 160V, i.e. and civil power normal power supply, then triode Q1 conducting, triode Q2 ends, and the colelctor electrode of triode Q2 exports high potential, and power switch chip TNY280 works.Resistance R6 provides cut-in voltage for TNY280; Resistance R7, resistance R8, resistance R ', electric capacity C4, diode D8, diode D9, for absorbing primary back-emf, protect TNY280.
Power switch chip TNY280 starts working, then the civil power of A electric capacity C220V through ac-dc converter circuit 35, will be transformed into the constant voltage being about 12V, be delivered to circuit thereafter.Ac-dc converter circuit 35 is made up of following element: diode D11, R9, electric capacity C7 provide accessory power supply for TNY280; Diode D10, electric capacity C6, electric capacity C9, inductance L 1 form output filter circuit; Zener diode TL2, the photoelectrical coupler U3 of resistance R10, resistance R11, resistance R13, resistance R14, resistance R15, electric capacity C8, three end parallel connections form output feedack network, thus output voltage is adjusted to constant 12V.
This output voltage is held by BATTERY+ on the one hand and GND holds and powers to induction control module 20 and switch module 30, is also held by BATTERY+ on the other hand and E-POWER holds accumulators 50 to charge.
In accompanying drawing 4, under green light (GREEN) is lighted and is represented normal lighting pattern that inductive lightning light fixture 10 is in by mains-supplied.Now, output voltage charges through diode D13, triode Q7, resistance R31, diode D18 accumulators 50.Triode Q5 and resistance R23 belongs to overcharge protection circuit 32.When battery 50 charges, output voltage makes red light being lit through triode Q5 and resistance R23; When battery 50 is full of gradually, its voltage will rise to about 12.5V, be greater than the output voltage of 12V, between the base stage of triode Q5 and emitter-base bandgap grading, potential difference is more and more less, gradually exits conducting district, and red light extinguishes, representative charging stops, thus reaches the object preventing overcharge.
When inductive lightning light fixture 10 enters emergency lighting pattern, when battery 50 starts to discharge, the triode Q6 conducting in over-discharge protection circuit 33 as shown in Figure 5.The base stage of triode Q6 is connected to 3 pin of the three end shunt regulator diode TL431 being used to provide voltage reference by resistance R27, resistance R24 and resistance R25 dividing point are connected to 1 pin of three end shunt regulator diode TL431.If the voltage of battery 50 is greater than 10V, the 1 pin current potential of three end shunt regulator diode TL431 is greater than 2.5V, is in conducting state, and 3 pin are electronegative potential, and triode Q6 keeps conducting; If cell voltage is less than 10V, the 1 pin current potential of three end shunt regulator diode TL431 is less than 2.5V, be in cut-off state, 3 pin are high potential, triode Q6 becomes cut-off from conducting, then battery 50 BATTERY end and E-POWER hold between be disconnected, battery 50 stop discharge, reach the object preventing overdischarge.
Next, under emergent light illumination mode, the circuit theory shown in accompanying drawing 4 is described.
Once decision circuitry 31 detects that the voltage of civil power is lower than 187V, then triode Q1 ends, triode Q2 conducting, and the colelctor electrode of triode Q2 exports electronegative potential, and power switch chip TNY280 closes, no-output voltage.Now, the BATTERY+ terminal potential of battery 50 is higher than E-POWER terminal potential, and battery 50 starts electric discharge.Q6 conducting, amber light (YELLOW) is lit, and represents that light fixture is in emergency rating.
Meanwhile, the MOS-G be connected with battery 50 negative pole holds also has electric current to pass through by continuing, and this MOS-G end belongs to state setting module, once MOS-G end has electric current to pass through, then this electric current will be transported to switch module 40, play the effect of setting signal, make LED 13 long bright.
After power failure a period of time, the staff at fire-fighting center, by manual unlocking generator 52, holds via N ' and L and to provide to system that AC220V's answer urgent telegram.This answers urgent telegram to enter rectifier bridge from N ', L end, and its power supply flow process and common civil power, without two, are through decision circuitry 31 equally, power switch chip TNY280 is made to work, then be converted into the direct current of 12V through ac-dc converter circuit 35, be supplied to LED 13, and accumulators 50 charges.
Meanwhile, also can enter photoelectrical coupler PC817 through diode D7, resistance R1, electric capacity C1 from the urgent telegram of answering of N ' end supply, cause triode Q3 conducting, triode Q4 ends, and triode Q4 colelctor electrode exports high potential and enters MOS-G end.This photoelectrical coupler PC817 belongs to state initialization circuit equally.Now, lasting generation current is also transferred to switch module 40 by MOS-G end, plays the effect of setting signal, makes LED 13 long bright.
Further, under emergency lighting pattern, state setting module also comprises diode D12 and diode D12B.If by the negative pole short circuit of diode D13 and diode D12B, even if MOS-G will be made to hold under emergency lighting pattern, do not have electric current to flow through yet, thus do not generate setting signal.Now, switch module 40 can only receive the induced signal of self-induction control module 20, thus realizes inductive lightning.Pressure inductive mode under this emergency lighting pattern, can be applicable to the not disaster such as fire, earthquake and has a power failure and be only the occasion of common power failure, play energy-conserving action.Such as, a manual inductive mode switch can be set between diode D13 and the negative pole of diode D12B.After power failure, inductive lightning light fixture 10 enters long bright pattern first automatically, then, keeper judges this time to have a power failure to be only common power failure, with regard to this inductive mode switch of manual unlocking, inductive lightning light fixture 10 is switched to pressure inductive mode, economize energy, make the electric power in battery 50 can maintain more of a specified duration.
Although in the present embodiment, hold the emergency power supply be connected to be generator 52 with N ', urgent telegram that what it provided answer is the alternating current of 220V, and emergency power supply herein also can be the dc source of the battery of one group of centrally connected power supply and so on.But corresponding, if the emergency power supply that N ' holds is direct current, then the structure of power control module 37 must change, and N ' end is after judging link 31, ac-dc converter circuit 31 will be walked around, export the direct current of 12V directly to induction control module 20 and light source portion 11.Certainly, the structure be connected with state setting module 30 is still absolutely necessary.
Accompanying drawing 6 is the circuit diagram of the induction control module 20 of inductive lightning light fixture 10, switch module 40 and LED 13.
Under normal lighting pattern, power control module 37 holds the output voltage to responding to control module 20 and export an about 12V by BATTERY+ end and GND.After the DC voltage converting circuit 27 through being made up of electric capacity C15, resistance R14, resistance R15, triode Q2, diode D1, electric capacity C13, electric capacity C14, this output voltage is reduced to 5V, and is input to 11 pin of control chip CS9803.
As shown in Figure 6, induction control module 20 also possesses a sensor circuit 24, and this sensor circuit 24 comprises an an infrared sensor PIR and control chip CS9803.Infrared sensor PIR in the present embodiment is pyroelectric sensor, is used for responding to extraneous infrared signal.Belong to if receive human body release infra-red radiation (wavelength is about 10 microns) signal, then hold output one to be about 2 pin of micro voltage signal to control chip CS9803 of 250mV from S.This micro voltage signal is amplified by control chip CS9803, generates the induced signal of about 5V, exports switch module to.
Control chip CS9803 is built-in with two-level operating amplifier, and the micro voltage signal sent by infrared sensor PIR is amplified.But in amplification process, owing to there is noise jamming, be easy to misoperation occurs.Particularly the susceptibility of infrared sensor PIR is higher, and clutter is more, disturbs larger.Therefore, be provided with a misoperation at the output of second level operational amplifier and prevent loop, be provided with an electric capacity C9 in this loop, play filter action, interfering signal is filtered out, thus ensure that the operation amplifier signal exported is reliable.In addition, misoperation prevents the electric capacity C9 in loop also can be changed to the elements such as inductance, as long as possess filter action.
Meanwhile, induction control module 20 also possesses a light-operated circuit 26, and this light-operated circuit 26 one end input voltage of receiving 5V same with control chip CS9803, other end ground connection, is equivalent in parallel with control chip CS9803.Further, this light-operated circuit 26 is also connected to 9 pin of control chip CS9803 with current constant mode.This light-operated circuit 26 has been connected a photo resistance RG., and ambient light is higher, and the resistance value of this photo resistance is less.
If ambient light is very high, the resistance of photo resistance RG is very little, then the voltage of light-operated circuit 26 is very little, be equivalent to ground connection zero potential, control chip CS9803 then in parallel with it is also equivalent to zero potential, its 11 pin is closed, even if infrared sensor PIR has sensed infrared signal, control chip CS9803 also cannot export induced signal.Otherwise if ambient light turns dark, the resistance of photo resistance RG increases, then voltage also increases, and removes the blockade of 11 pin to control chip CS9803, and control chip CS9803 can generate according to the induction result of infrared sensor PIR and export induced signal thereupon.
In addition, also possess a delay circuit be made up of oscillating circuit 25 in sensor circuit 24, its effect makes induction control module 20 when infrared sensor PIR has responded to less than infrared signal, still continues generate and export induced signal in certain hour.So, LED 13 is just unlikely to pedestrian just past just extinguishing suddenly, humanized.
BATTERY+ end is held with GND and is also powered to switch module 40 and LED 13 simultaneously.Switch module 40 has a current constant control chip PT4115, and this current constant control chip PT4115, by conducting after 3 pin reception induced signals or setting signal, exports a constant current from 4 pin, LED 13 is lighted.Under normal lighting pattern, switch module 40 through diode D2 intermittent from induction control module 20 receive induced signal, then make LED 13 intermittence light; Under emergency lighting pattern, switch module 40 receives lasting setting signal through MOS-G end and D3, then make LED 13 long bright.If switch module 40 does not receive any signal of telecommunication, then stop the output of constant current, LED 13 is extinguished.
LED 13 is also contacted with inductance L 1 phase, and this inductance L 1 plays filter action, illumination is stablized and does not glimmer.
In the present embodiment, switch module 40 realizes the switch control rule to LED 13 by current constant control chip PT4115, but is not limited to this kind of switch control rule mode.As long as can ensure receive induced signal or setting signal season LED 13 light, also current constant control chip can be replaced with the elements such as such as FET.

And embodiment 3 and the difference of embodiment 2 are, in embodiment 3, the battery 50 as emergency power supply and the necessary artificial generator 52 opened is not comprised separately in every inductive lightning light fixture 10, but whole inductive lightning system 60 shares a ups power 51, with civil power and a group storage battery 50 while of this ups power 51.When civil power power-off, UPS will automatically switch to battery 50 via the power supply of N ' and L end, after state setting module 30 receives the electric current that N ' holds, export the status signal continued to switch module 40.
As embodiment 3, the inductive lightning system 60 only possessing the emergency power supply of centrally connected power supply is called as integrated system.The advantage of integrated system is that stand-by power supply only has one group, is convenient to administer and maintain.Weak point is then that the capacity of the battery in ups power 51 must be enough to meet the demand of all inductive lightning light fixtures 10, once this ups power 51 power-off, all inductive lightning light fixtures 10 will extinguish simultaneously.And for aedicula or residential houses, the cost building independently fire-fighting center is too high.
And if by the parallel connection of the inductive lightning light fixture 10 of many embodiments 1, the inductive lightning system formed 60 is called as independently formula system.Its advantage is that every inductive lightning light fixture 10 all has independently battery 50, can not produce interference each other.Even if there is the electricity of battery 50 in an inductive lightning light fixture 10 to use up, other inductive lightning light fixtures 10 also can not be affected.And battery 50 capacity does not need too large, the battery that lithium battery etc. is comparatively light can be adopted.But independently formula system also has its weak point, the cost being exactly every inductive lightning light fixture 10 is higher, economical not for very intensive, the total huge heavy construction of light fixture of illumination.
Embodiment 2 combines integrated system and the independently ambilateral advantage of formula system, can power separately, again can centrally connected power supply, and flexibility ratio and reliability are all quite high, but implementation cost is also higher.
In addition, in embodiment 3, between the switch module 40 and light source portion 11 of every inductive lightning light fixture 10, be equipped with an interlock terminal 61, this interlock terminal 61 can be connected with the interlock terminal of other inductive lightning light fixtures 10 in system, realizes the interlock of all inductive lightning light fixtures 10 in inductive lightning system 60.When a LED 13 any in system is lighted, all the other LED 13 be connected also will be lighted simultaneously; Only have when the induction control module 20 of all inductive lightning light fixtures 10 is all responded to less than signal, all LED 13 in whole system just can be extinguished simultaneously.This kind of linkage pattern is applicable to being applied in the broader space such as hall, tunnel.Such as, after vehicle enters tunnel, all LED in whole piece tunnel will be lighted simultaneously, there will not be the phenomenon making driver's fear because second half section tunnel is very dark, fully ensure that driving safety.
These interlock terminals 61 also can be unified to be connected to a control centre, then "ON", "Off" signal is directly sent by the operator being positioned at control centre, not receive induced signal or emergency parachute at switch module 40, but when operator judges to need illumination, artificial lightening LED lamp 13.
