Background technology

Warning lamp plays admittedly important function, such as the warning of construction site hazardous location, road in numerous occasions Construction temporary-warning, offshore lighthouse warning etc.；Underpass needs illuminate for 24 hours, and some residential quarters street lamps need whole at night Evening illumination, these illumination measures are all particularly important to the life of the mankind and the safety of property, are not allow for any interruption.

But good again, expensive again illumination measures may also be out of order, or loose contact or the rupture of light fixture fracture of wire.Normally The light fixture of work can not make a reservation for the life-span of oneself, the joint of light fixture due to rainwater corrosion possible loose contact at any time, once There is any above-mentioned failure, very big inconvenience will be caused to the normal life of the mankind, at this moment can enable emergency light electricity Road, but emergency light accumulator capacity is too small, typically can not adhere to how long illuminating.

For such case, a kind of illuminator is designed, although this illuminator can not prevent burning for light fixture, When can accomplish that king light tool does not work regardless of reason, as long as supply voltage is normal, standby warning lamp energy turn on automatically, keep shining It is bright, and start audible alarm, prompt administrative staff to change damage light fixture.In addition, standby warning lamp needs also may be used when actively lighting To light manually, to represent that equipment is out of order.The thinking is totally different from the design of emergency light circuit, is another direction Emergency lighting theory.

The content of the invention

The design technical problem to be solved be to provide it is a kind of it is simple in construction, cheap, using it is reliable, can protect automatically The illuminator of the long-term continuous illumination of Special zone is held, when the damage of king light tool, standby light fixture are lighted, sound can be simultaneously emitted by Sound is alarmed, and reminds staff to change the king light tool of damage in time.

The thinking is totally different from the design of emergency light circuit, is the emergency lighting theory in another direction.

Emergency light is in normal illumination power failure, effectively can illuminate and show fire escape, or energy Persistently illuminate and a kind of light fixture of non-stop run, be widely used in public place and be unable to the place of intermittent illumination, emergency light mould The shortcomings that formula is that emergency light accumulator capacity can not be done too big, therefore typically can not adhere to how long illuminating.

Automatic spare device illuminating alarm lamp can not be lighted for various reasons in king light tool, may cause unsafe factor In the case of, another emergency lighting design concept of proposition.General thought be king light tool loop can not turn in the case of, The standby light fixture of turn on automatically, in terms of this respect, automatic spare device illuminating alarm lamp design concept is managed with emergency light emergency lighting design The thinking of thought is different.

Automatic spare device illuminating alarm lamp design electrical principle it is very simple, as shown in Figure 2, except king light tool and it is standby With outside light fixture the two illuminators, also a set of control circuit, including low-tension supply generation circuit, sample circuit, anti-phase electricity Road, current amplification circuit, relay circuit；Power frequency 220V AC powers are sequentially connected in series structure with king light tool LAMP1, inductance L Into the main lamp circuit；Same power frequency 220V AC powers and relay J normally opened end, standby light fixture LAMP2 are sequentially connected in series The standby lamp circuit is connected and composed, main lamp circuit is connected with standby light fixture circuit in parallel；Low-tension supply generation circuit produces Raw 12V DC voltage-stabilized power supply and resistance R1, tongue tube K, resistance R2, publicly it is sequentially connected in series composition detection king light tool and is The sample circuit of no normal work；Transistor Q1 forms the negative circuit, the tongue tube K and resistance R2 of sample circuit Connection end connect transistor Q1 base stage in addition, provide positive working bias voltage for transistor Q1 emitter junction；Transistor Q2 structures Into the current amplification circuit, transistor Q1 C poles connection transistor Q2 base stage, 12V DC voltage-stabilized power supply with resistance R3, often Make and break close SW2, transistor Q1 C-E poles, be publicly sequentially connected in series, for transistor Q2 emitter junction, to provide forward bias electric Pressure；Relay J coil windings are connected in parallel with diode D1 forms the relay circuit, and 12V DC voltage-stabilized power supply, after Appliance circuit, transistor Q2 C-E poles, be publicly sequentially connected in series, provide operating current for relay J windings；Piezoelectricity honeybee Ring device is connected in parallel with relay J coil windings and forms the warning circuit.

The king light tool and standby light fixture, LAMP1 are main illuminator, and normal condition illumination is provided by it, LAMP2 For standby lighting light fixture, when king light tool does not work regardless of reason, stand-by lamp must be lighted, to ensure that people's lives are pacified Entirely.

The low-tension supply, it is 12V DC power supply, is exchanged by 220V, transformer T, bridge heap B, electric capacity C₁And voltage stabilizing two Pole pipe D₂Produce, as low-voltage circuit power supply.

The sample circuit, refer to the on off operating mode that king light tool is judged by a certain sample devices, so as to realize major and minor lamp Has the switching of illumination；Tongue tube can realize this function, a tongue tube inherently change-over switch, when permanent magnet leans on When the magnetic field that nearly tongue tube or the coil electricity being wound on tongue tube are formed magnetizes reed, the contact part of reed will be by magnetic Gravitational attraction, when attraction is more than the elastic force of reed, normal opened contact will adhesive；When magnetic force reduces to a certain extent, contact Opened by the elastic force of reed, as shown in Figure 3, king light tool supply line can seal in an inductance coil（5 circles）, will be dry Reed pipe is inserted perpendicularly into inductance coil center.

The negative circuit, by triode Q₁To realize, triode Q₁Work in common emitter amplifier state, power supply 12V passes through triode Q₁The biasing resistor R of base stage₁、R₂For triode Q₁Base stage provides bias voltage, by designing suitably just Make Q to bias voltage₁Saturation conduction, now triode Q₁Equivalent to one phase inverter.

The current amplification circuit is by triode Q₂Realize, if main bulb is normally lighted, triode Q₂Base voltage is changed into Level "0", Q₂End because B-E forward bias voltages are less than 0.7V, now Q₂C-E electrode currents be 0, relay J winding End loses power supply, and its normally opened proper normal off is opened, and spare bulb is not powered and is in OFF state；Direct current buzzer loses power supply not Ring.

If being out of order because king light has LAMP1 loose contacts or bulb such as have broken at the reason, no current flows through in inductance L, does Reed pipe disconnects dry reed demagnetization, the two poles of the earth due to losing magnetic fields, triode Q₁Base stage loses bias voltage, is changed into ending State, power supply 12V pass through resistance R₃It is added to triode Q₂In base stage, make Q₂Saturation conduction immediately, now Q₂Put for an electric current Big device, relay J wind electric normally opened end adhesive, spare bulb are lighted, and direct current buzzer alarm sounds.

Switch SW₂Opening can artificially light spare bulb, be designed as special requirement.The face of spare bulb and main bulb Color can be distinguished slightly, for example main bulb normal color, spare bulb show slightly yellow, are shown with warning.

Brief description of the drawings

Accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 are used for providing further understanding the design, form the present utility model application and hair A part for bright application, accompanying drawing 1 are the electrical schematic diagrams of emergency light circuit, by the contrast of both schematic diagrams, embody the design Particularity；Accompanying drawing 2 is the electrical schematic diagram of the design automatic spare device illuminating alarm lamp；Accompanying drawing 3 is the critical elements of the design One of tongue tube fundamental diagram.

Embodiment

Accompanying drawing 1 is the electrical schematic diagram of the contrast design circuit emergency light of the design, and emergency light is in normal illumination During power failure, fire escape effectively can be illuminated and shown, or can continue to illuminate and a kind of light fixture of non-stop run. It is widely used in public place and is unable to the place of intermittent illumination.

For the emergency lighting system that the country uses based on self-powered independent control type, normal power source is connected to general lighting confession In electrical circuit, usually emergency light battery is charged, when normal power source is cut off, stand-by power supply（Battery）Automatic power.This The each lamp interior of emergency light of kind form has the substantial amounts of electronic component such as transformation, voltage stabilizing, charging, inversion, battery, should Anxious lamp using, maintenance, failure when battery be both needed to discharge and recharge.

Another kind is centrally connected power source centralized Control type, without independent current source in emergency luminaire, during normal illumination power failure, by Central power supply system is powered, and in the emergency lighting system of this form, the complicated electronic circuit of all lamp interiors is saved , emergence lighting lamp is no different with common light fixture, and central power supply system is arranged in special room, and Fig. 1 is a simple Emergency light circuit figure, principle is simple, no longer illustrates, but this is the emergency light of a LED illumination, if using civil power 220V Lighting bulb becomes the more of complexity it is necessary to consider inverter circuit.

By described above as can be seen that emergency light pattern realizes that the essence of continuous illumination is to be used as to answer using battery Anxious mains lighting supply, then it the shortcomings that just it is obvious that emergency light accumulator capacity can not do too big, therefore general emergency light illumination It can not adhere to illuminating for a long time, this is to have run counter to the light illumination mode demand required for us.

Different from emergency light light illumination mode, automatic spare device illuminating alarm lamp for various reasons can not in king light tool Light, in the case of unsafe factor may being caused, another emergency lighting design concept of proposition.General thought is in king light The standby light fixture of turn on automatically, it is different from the thinking that emergency light designs from emergency lighting in the case that tool loop can not turn on.

The electrical principle of the design is very simple, as shown in Figure 2, except king light tool and standby light fixture the two illumination Outside light fixture, also a set of control circuit, including low-tension supply generation circuit, sample circuit, negative circuit, current amplification circuit, The partial circuit of relay circuit five, is explained in detail below.

LAMP1 is main illuminator, and normal condition illumination is provided by it, and LAMP2 is standby lighting light fixture, once king light When tool does not work regardless of reason, stand-by lamp must be lighted, to ensure people's lives safety.In addition, standby warning lamp（It is exactly Standby light fixture）Need it artificially to be lighted when actively lighting, to represent that equipment is out of order, be achieved in that and opened normally closed Close SW₂Open, you can artificially light spare bulb.In a word no matter that situation, at the time of spare bulb is lighted, it is necessary to while companion There is sound warning, remind holdee to pay attention to Environmental security, the color of spare bulb should be otherwise varied with main bulb color.

Low pressure 12V DC power supply is exchanged by 220V, transformer T, bridge heap B, electric capacity C₁And voltage-regulator diode D₂Produce, make For low-voltage circuit power supply.

A tongue tube inherently change-over switch, when permanent magnet leads to close to tongue tube or the coil being wound on tongue tube When the magnetic field of electric forming magnetizes reed, the contact part of reed will be magnetically attracted, when attraction is more than the elastic force of reed When, normal opened contact will adhesive；When magnetic force reduces to a certain extent, contact is opened by the elastic force of reed, as shown in Figure 3.

In circuit accompanying drawing 2, inductance L and tongue tube K co-ordinations, inductance L are connected in king light tool loop, and tongue tube is vertical Inductance L centers are inserted, have no current by the way that main bulb is bright, inductance L produces magnetic field, then dry spring to sense king light tool loop Pipe K is connected, and main bulb does not work, inductance L loses magnetic field, then tongue tube K disconnects.This partial circuit needs specially one inductance of design Be connected on king light tool loop in, pays attention to that the inductance number of turn should not be too many, 5 circles or so, the number of turn easily cause too much generate heat and Eddy-current loss increases；Or simply should not inductance, by king light have return lead on tongue tube loosely around upper 5 circle, with replace Inductance, reason are the same.

If main bulb is normally lighted, tongue tube is magnetized so as to connect by conductive coil, triode Q₁Work in common emitter Amplifier status, power supply 12V pass through triode Q₁The biasing resistor R of base stage₁、R₂For triode Q₁Base stage provides biased electrical Pressure, makes Q by the forward bias voltage for designing appropriate₁Saturation conduction, now triode Q₁Equivalent to one phase inverter；Triode Q₂Base voltage is changed into level "0", Q₂End because B-E forward bias voltages are less than 0.7V, relay J winding end loses Power supply, its normally opened proper normal off are opened, and spare bulb is not powered and is in OFF state；Direct current buzzer loses power supply and not rung.

If being out of order because king light has LAMP1 loose contacts or bulb such as have broken at the reason, no current flows through in inductance L, does Reed pipe disconnects dry reed demagnetization, the two poles of the earth due to losing magnetic fields, triode Q₁Base stage loses bias voltage, base level For 0, Q₁End because B-E poles forward bias voltage is less than 0.7V；Power supply 12V passes through resistance R₃It is added to triode Q₂Base On extremely, make Q₂Saturation conduction immediately, now Q₂For a current amplifier, relay J winds to obtain electric normally opened end adhesive, spare bulb Light, and direct current buzzer alarm sounds.Because lighting apparatus is in PE, alarm not adjusted too high, if hidden If now hearing, in order to avoid cause the public chaotic.

Switch SW₂Opening can artificially light spare bulb, be designed as special requirement.The face of spare bulb and main bulb Color can be distinguished slightly, for example main bulb normal color, spare bulb show slightly yellow, are shown with warning.

This automatic spare device warning lamp is not our common emergency light patterns, passes through the comparison with emergency light circuit, sense Feel that it provides a thinking from other side to us, the illuminator of public place is if important, Ke Yitong Cross automated back-up lighting installation, there is provided continuous illumination.Humanized service is provided with this, is more convenient to resident, it is right The life of the people provides higher safety assurance.If theory overall planning together with emergency light technology, if more humane.

The shortcomings that design is separately to add a set of illuminator as backup, and a set of control circuit of increase, is being shone No small increase is had in bright cost, it is also more more complex than general illumination in maintenance.But for some special lighting locations Special lighting, for people's lives conveniently, safely, the increase of these illumination costs is negligible.

The automatic spare device warning light circuit is simple in construction, thinking is ingenious, and cost of manufacture is very cheap, is quite suitable for public affairs Garden, building site, plant area, underpass, offshore lighthouse etc. need the region of special lighting pattern to use.
