Description
Technical field
The present invention relates to a kind of inductive lightning light fixture and a kind of inductive lightning system that uses this inductive lightning light fixture, be specifically related to a kind of inductive lightning light fixture and inductive lightning system that has normal lighting function and function of emergency illumination concurrently.
Background technology
The effect of emergency lighting is to provide illumination for fire-fighting and rescue work when running into disaster such as fire, earthquake, thereby ensures the life security of personnel in the building.Particularly for increasing skyscraper in the city now, in case disaster takes place, the difficulty of its fire-fighting and rescue work is very big, and is high especially to the lighting quality and the stability requirement of illuminator.
Yet emergency luminaire and emergency lighting system on the market is all not fully up to expectations at aspects such as lighting quality, stability and maintenance costs at present.
And the key reason that produces various weak points is: normal lighting and emergency lighting are adopted is two to overlap 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 innerly still comprise 2 independent light sources.Wherein, that the normal lighting system usually adopts is high-power (40～60 watts, even higher) light fixture is as light source, this is in order to guarantee brightness of illumination and to adapt to alternating voltage, reducing cost simultaneously; Emergency lighting then must be adopted comparatively energy-conservation small-power (about 5～20 watts) light source, otherwise can't provide enough power supply supplies for a long time as the storage battery of stand-by power supply.
Normal lighting and emergency lighting are divided into two overlap independently that the shortcoming of system mainly shows following several respects:
1, a cover emergency lighting system additionally is installed again outside the normal lighting system, will inevitably be increased installation cost.And emergency lighting system must regularly detect, and light source and storage battery also will in time be changed according to useful life, and maintenance cost is very high.Even regularly emergency lighting system is safeguarded on request, but, also can't in time find, have potential safety hazard all the time even there is light fixture to damage because its utilization rate is low.In addition, many builders respond with idea of leaving things to chance, only pursue at a low price and lightweight, and have ignored regular maintenance, very easily generation accident when disaster takes place.
2, when when normal lighting switches to emergency lighting, unexpected variation can take place in brightness of illumination, raises fear easily.The light-source brightness of emergency lighting is lower, is 5%～10% of normal lighting only, and is usually located at staircase, turning, edge, corridor etc. and locates, and density is set much smaller than normal lighting.Particularly in some pays attention to artistry and building attractive in appearance, the light source position of emergency lighting will be more hidden.After the outage of generation disaster, a slice is dim in the building, only has corridor and staircase to appear faint light, and people inevitably pour into the light source position in a large number, confusion takes place easily and trample accident.
3, normal lighting and emergence lighting lamp are not all supported wide voltage, and the voltage fluctuation amplitude is big slightly, just can't light.According to the security against fire standard, when being lower than 187V, the voltage of civil power just is considered as outage, and emergency power supply must be enabled, and the startup of emergency power supply must be before voltage is reduced to 132V, finished.So, in this voltage range of 187V～132V,, then occur the normal lighting system probably, and also the do not have enough time phenomenon that starts of emergency lighting system is referred to as illumination to disconnect, and has a strong impact on safety because undertension extinguishes if switch not prompt enoughly.
4, the Chang Yong emergence lighting lamp and the life of storage battery are all shorter, and regular maintenance needs frequent the replacing, and cost is higher.Such as, the light source of emergency lighting is selected lower quartz lamp or Halogen lamp LED of life-span usually for use; Storage battery is then selected the nickel-cadmium cell even the lead acid accumulator of low performance for use.Though the hydrogen battery long service life, its electric power storage ability can't guarantee long-time power supply not as traditional storage battery, can't be applied in the emergency lighting system.

The setting state module can generate a setting signal (step 10), and this setting signal is sent to switch module 40 (step 11) constantly after receiving the electric power that storage battery 50 provides.
Embodiment 2:
Accompanying drawing 3 is the circuit diagram of the inductive lightning system 60 of the embodiment of the 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 among the embodiment 2 comprises light source portion 11, power supply control module 37, induction control module 20, setting state module 30, switch module 40 and storage 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 fixture 10 shared one group of power supply parallel with one another have promptly constituted inductive lightning system 60.
And the difference of embodiment 2 and embodiment 1 is that inductive lightning system 60 also comprises a generator 52 that can serve as emergency power supply.This generator 52 is connected with the control module 37 of powering by L end and N ' end, generally is arranged in the fire-fighting of building intracardiac.
Under the normal lighting pattern, generator 52 is not worked, and N ' holds outage, and power supply control module 37 is subjected to civil power through N, L termination.In case decision circuitry 31 is judged the civil power outage, the control module of then powering 37 at first will automatically switch to being powered by storage battery 50, then, staff's manual unlocking generator 52 at fire-fighting center, provide from N ' end and to answer urgent telegram, so power supply control module 37 is held by answering the urgent telegram power supply from being switched to by storage battery power supply through N ' and L.Simultaneously, the setting state module 30 that links to each other with N ' and L end detects answers urgent telegram, sends a lasting setting signal to switch module 40, makes that the power supply minister is bright.
Accompanying drawing 4 is the power supply control module 37 of inductive lightning light fixture 10 and the circuit diagram of storage battery 50, and accompanying drawing 5 is the circuit diagram of the over-discharge protection circuit 33 of storage battery 50.
At first, under the normal lighting pattern, the circuit theory shown in the accompanying drawing 4 describes.
As shown in Figure 4, the civil power of AC220V enters rectifier bridge through N, L end, after big capacitor C 2 filtering, enters the decision circuitry of being made up of resistance R 2, resistance R 3, resistance R 4, resistance R 5, capacitor C 3, triode Q1, triode Q2 31 again.This decision circuitry 31 is by resistance R 2, resistance R 3, resistance R 4 sampling civil powers, 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, the collector electrode output high potential of triode Q2, mains switch chip TNY280 work.Resistance R 6 provides cut-in voltage for TNY280; Resistance R 7, resistance R 8, resistance R ', capacitor C 4, diode D8, diode D9 be used to absorb the primary back-emf, protection TNY280.
Mains switch chip TNY280 starts working, and then the civil power of A capacitor C 220V will be transformed into the constant voltage that is about 12V through ac-dc converter circuit 35, be delivered to circuit thereafter.Ac-dc converter circuit 35 is made up of following element: diode D11, R9, capacitor C 7 provide accessory power supply for TNY280; Diode D10, capacitor C 6, capacitor C 9, inductance L 1 are formed output filter circuit; Voltage stabilizing didoe TL2, the photoelectrical coupler U3 of resistance R 10, resistance R 11, resistance R 13, resistance R 14, resistance R 15, capacitor C 8, three end parallel connections forms the output feedback network, thereby output voltage is adjusted to constant 12V.
This output voltage is held to induction control module 20 and switch module 30 power supplies by BATTERY+ end and GND on the one hand, on the other hand also by BATTERY+ end and 50 chargings of E-POWER end accumulators.
In the accompanying drawing 4, green light (GREEN) is lighted and is represented inductive lightning light fixture 10 to be under the normal lighting pattern by mains-supplied.At this moment, output voltage is through diode D13, triode Q7, resistance R 31,50 chargings of diode D18 accumulators.Triode Q5 and resistance R 23 belong to overcharge protection circuit 32.When storage battery 50 chargings, output voltage makes red light light through triode Q5 and resistance R 23; When storage battery 50 is full of gradually, its voltage will rise to about 12.5V, greater than the output voltage of 12V, potential difference is more and more littler between the base stage of triode Q5 and the emitter-base bandgap grading, withdraws from the conducting district gradually, and red light extinguishes, representative charging stops, and prevents the purpose of overcharging thereby reach.
When inductive lightning light fixture 10 enters the emergency lighting pattern, when storage battery 50 begins to discharge, the triode Q6 conducting in the 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 parallel voltage-stabilizing diode TL431 that are used to provide voltage reference by resistance R 27, and resistance R 24 and resistance R 25 dividing points are connected to 1 pin of three end parallel voltage-stabilizing diode TL431.If the voltage of storage battery 50 is greater than 10V, the 1 pin current potential of three end parallel voltage-stabilizing diode TL431 is in conducting state greater than 2.5V, 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 parallel voltage-stabilizing diode TL431 is less than 2.5V, be in cut-off state, 3 pin are high potential, triode Q6 is become by conducting and ends, then be disconnected between the BATTERY of storage battery 50 end and the E-POWER end, storage battery 50 stops discharge, reaches the purpose that prevents overdischarge.
Next, under emergent light illumination mode, the circuit theory shown in the accompanying drawing 4 describes.
Be lower than 187V in case decision circuitry 31 detects the voltage of civil power, then triode Q1 ends, triode Q2 conducting, and the collector electrode output electronegative potential of triode Q2, mains switch chip TNY280 closes, no-output voltage.At this moment, the BATTERY+ terminal potential of storage battery 50 is higher than the E-POWER terminal potential, and storage battery 50 begins discharge.The Q6 conducting, amber light (YELLOW) is lighted, and the expression light fixture is in emergency rating.
Simultaneously, the MOS-G end that links to each other with storage battery 50 negative poles also will continue have electric current to pass through, and this MOS-G end belongs to the setting state module, in case the 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 that LED lamp 13 is long bright.
After a period of time that has a power failure, the staff at fire-fighting center provides the urgent telegram of answering of AC220V with manual unlocking generator 52 to system via N ' and L end.This answers urgent telegram to enter rectifier bridge from N ', L end, and its power supply flow process and common civil power do not have two, is through decision circuitry 31 equally, make mains switch chip TNY280 work, be converted into the direct current of 12V then through ac-dc converter circuit 35, be supplied to LED lamp 13, and accumulators 50 chargings.
Simultaneously, answer urgent telegram also can pass through diode D7, resistance R 1, capacitor C 1 to enter photoelectrical coupler PC817, cause triode Q3 conducting from what N ' end was supplied with, triode Q4 ends, and triode Q4 collector electrode output high potential enters MOS-G and holds.This photoelectrical coupler PC817 belongs to the setting state circuit equally.At this moment, the MOS-G end also will continue to produce current delivery to switch module 40, play the effect of setting signal, make that LED lamp 13 is long bright.
Further, under the emergency lighting pattern, the setting state module also comprises diode D12 and diode D12B.If with the negative pole short circuit of diode D13 and diode D12B,, do not have electric current to flow through yet, thereby do not generate setting signal even will make the MOS-G end under the emergency lighting pattern.At this moment, switch module 40 can only receive the induced signal of self-induction control module 20, thereby realizes inductive lightning.Pressure inductive mode under this emergency lighting pattern, can be applicable to not is that disasters such as fire, earthquake have a power failure and only are the occasion of common power failure to play energy-conserving action.For example, a manual inductive mode switch can be set between the negative pole of diode D13 and diode D12B.After the power failure, inductive lightning light fixture 10 enters long bright pattern at first automatically, then, the keeper judges that this time having a power failure only is common power failure, just manually open this inductive mode switch, inductive lightning light fixture 10 is switched to the pressure inductive mode, and energy savings makes the electric power in the storage battery 50 can keep more for a long time.
Though in the present embodiment, the emergency power supply that is connected with N ' end is a generator 52, the urgent telegram of answering that it provides is the alternating current of 220V, and emergency power supply herein also can be the DC power supply of storage battery of one group of centrally connected power supply and so on.But corresponding, if the emergency power supply of N ' end is a direct current, the structure of the control module of then powering 37 must change, and N ' end is after connecting road 31 through judgement, to walk around ac-dc converter circuit 31, directly to the direct current of responding to control module 20 and light source portion 11 output 12V.Certainly, the structure that is connected with setting state module 30 still is absolutely necessary.
Accompanying drawing 6 is the circuit diagram of induction control module 20, switch module 40 and the LED lamp 13 of inductive lightning light fixture 10.
Under the normal lighting pattern, power supply control module 37 is by BATTERY+ end and the output voltage of GND end to about 12V of induction control module 20 outputs.After the process DC voltage converting circuit 27 that is made of capacitor C 15, resistance R 14, resistance R 15, triode Q2, diode D1, capacitor C 13, capacitor C 14, 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 infrared sensor PIR and a control chip CS9803.Infrared sensor PIR in the present embodiment is a pyroelectric sensor, is used for responding to extraneous infrared signal.If receive belong to that human body discharges infrared radiation (wavelength is about 10 microns) signal, then from 2 pin that are about the micro voltage signal of 250mV to control chip CS9803 of S end output.Control chip CS9803 amplifies this micro voltage signal, generates the induced signal about 5V, exports switch module to.
Control chip CS9803 is built-in with two-level operating amplifier, and the micro voltage signal that infrared sensor PIR is sent amplifies.But in amplification process,, be easy to take place misoperation owing to there is noise jamming.Particularly the susceptibility of infrared sensor PIR is high more, and clutter is many more, disturbs big more.Therefore, be provided with a misoperation at the output of second level operational amplifier and prevent the loop, be provided with a capacitor C 9 in this loop, play filter action, interference signal is filtered out, thereby the computing amplifying signal that guarantees output is reliable.In addition, misoperation prevents that the capacitor C 9 in the loop also can be changed to elements such as inductance, all can as long as possess filter action.
Simultaneously, induction control module 20 also possesses a light-operated circuit 26, and these light-operated circuit 26 1 ends and control chip CS9803 receive the input voltage of 5V equally, and other end ground connection is equivalent in parallel with control chip CS9803.And this light-operated circuit 26 also is connected to 9 pin of control chip CS9803 with current constant mode.The photo resistance RG. that on this light-operated circuit 26, connected, extraneous brightness is high more, and the resistance value of this photo resistance is more little.
If extraneous brightness 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 the ground connection zero potential, control chip CS9803 then in parallel with it also is equivalent to zero potential, its 11 pin is closed, even infrared sensor PIR has sensed infrared signal, control chip CS9803 also can't export induced signal.Otherwise dark if extraneous brightness is changeed, the resistance of photo resistance RG increases, and then voltage also increases thereupon, removes the blockade to 11 pin of control chip CS9803, and control chip CS9803 can generate and export induced signal according to the induction result of infrared sensor PIR.
In addition, also possess a delay circuit 25 that is made of oscillating circuit in the sensor circuit 24, its effect is to make induction control module 20 under infrared sensor PIR has responded to situation less than infrared signal, still continues in the certain hour to generate and the output induced signal.So, LED lamp 13 just is unlikely to the pedestrian just through just extinguishing suddenly, and is humanized.
The BATTERY+ end is also powered to switch module 40 and LED lamp 13 simultaneously with the GND end.Switch module 40 has a constant current control chip PT4115, and this constant current control chip PT4115 receives conducting behind induced signal or the setting signal by 3 pin, from constant current of 4 pin output, LED lamp 13 is lighted.Under the normal lighting pattern, switch module 40 receives induced signal through diode D2 is intermittent from induction control module 20, then makes LED lamp 13 intermittences light; Under the emergency lighting pattern, switch module 40 receives lasting setting signal through MOS-G end and D3, then makes LED lamp 13 long bright.If switch module 40 does not receive any signal of telecommunication, then stop the output of constant current, LED lamp 13 extinguishes.
In the present embodiment, switch module 40 is realized the switch of LED lamp 13 is controlled by constant current control chip PT4115, but is not limited to this a kind of switch control mode.As long as can guarantee to light receiving induced signal or setting signal LED lamp in season 13, also the constant current control chip can be replaced with such as elements such as field effect transistor.

And the difference of embodiment 3 and embodiment 2 is, among the embodiment 3, do not comprise separately in every inductive lightning light fixture 10 as the storage battery 50 of emergency power supply and the generator 52 that must manually open, but whole inductive lightning system 60 shared ups powers 51, this ups power 51 is simultaneously and a civil power and a group storage battery 50.When civil power cuts off the power supply, UPS will automatically switch to storage battery 50 via N ' and the power supply of L end, after setting state module 30 receives the electric current of N ' end, to the lasting status signal of switch module 40 outputs.
As embodiment 3, the inductive lightning system 60 that only possesses 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 has only one group, is convenient to administer and maintain.Weak point is that then the capacity of the storage battery in the ups power 51 must be enough to satisfy the demand of all inductive lightning light fixtures 10, in case these ups power 51 outages, all inductive lightning light fixtures 10 will extinguish simultaneously.And for aedicula or residential houses, the cost of building fire-fighting center independently is too high.
And if with inductive lightning light fixture 10 parallel connections of many embodiment 1,60 of formed inductive lightning systems are called as stand-alone system respectively.Its advantage is that every inductive lightning light fixture 10 all has independently storage battery 50, can not produce interference each other.Even have the electricity of storage battery 50 in the inductive lightning light fixture 10 to use up, also can not influence other inductive lightning light fixtures 10.And storage battery 50 capacity do not need too big, can adopt comparatively light storage batterys such as lithium battery.But stand-alone system also has its weak point respectively, and the cost that is exactly every inductive lightning light fixture 10 is higher, and is economical inadequately for very intensive, the total huge heavy construction of light fixture of illumination.
2 of embodiment combine integrated system and the ambilateral advantage of stand-alone system respectively, 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, among the 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 the system, realizes the interlock of all inductive lightning light fixtures 10 in the inductive lightning system 60.Any LED lamp 13 is lighted in system, and all the other LED lamps 13 that link to each other also will be lighted simultaneously; Have only when the induction control module 20 of all inductive lightning light fixtures 10 is all responded to less than signal, all the LED lamps 13 in the whole system just can extinguish simultaneously.This kind linkage pattern is fit to be applied in the broader space such as hall, tunnel.Such as, after vehicle entered the tunnel, all the LED lamps in the whole piece tunnel will be lighted simultaneously, the phenomenon owing to the very dark driver's of the order fear in second half section tunnel can not occur, have fully guaranteed driving safety.
These interlock terminals 61 also can unify to be connected to a control centre, directly send " opening ", " pass " signal by the operator who is positioned at control centre then, so that do not receive induced signal or emergency signal at switch module 40, but the operator judges when needing illumination, manually lights LED lamp 13.
