Description
Technical field
The present invention relates to emergency lighting or instruction equipment, in particular a kind of emergency light powered using capacitor and its confession
Method for electrically.
Background technology
Electric capacity, especially super capacitor, power supply effectiveness can be had by being verified.But because the off-capacity of electric capacity,
And electric discharge is too fast, is not that can be suitably used for most electric power thus supplied.But, the power supply needs of emergency set supply with general
Electric situation demand is precisely the presence of difference.For example, in the case where night powers off suddenly, emergency light enables capacitance module power supply, carries
For illumination；In the case where fire powers off, emergency light can also be powered using stand-by power supply, emitted beam and penetrated smog
Direction indication, outlet, position etc. function are provided.Based on security needs, many indoor and outdoor places are required for illuminator, and
Need the lighting apparatus being equipped with case of emergency.Emergency light can not only provide illumination, also provide the function of instruction.Moreover, city
Electric recovery that typically can be quickly, or uninterrupted power source, interim generator can all recover normally to power as soon as possible.It is so emergent
In the case of required for power supply need time do not grow.
One for traditional emergency light it is very unfavorable the defects of be that it is nickel that traditional emergency light, which uses emergency service source,
Cadmium cell or Ni-MH battery.Because nickel-cadmium cell or Ni-MH battery have memory effect, although recursive fill
Discharge of electricity, but because electric discharge can thoroughly not produce memory effect.Charge once, electricity will reduce once, until can not
Untill use.This is damage and the shortcoming not being avoided that for traditional emergency light.Emergency light is because of power failure and after use, no
Long time civil power will recover, and battery discharge is not completed just to start to charge up.Battery electric quantity can be in persistently to reduce
Trend, then the service life of traditional emergency light is just reduced always.Battery just necessarily needs if there is powerup issue, emergency light
Change battery.The life-span of emergency power supply can reach more than 5 years, and the nickel-cadmium cell and Ni-MH battery in traditional emergency light
Normal service life only has 2 years, and not only user is changed and brought inconvenience, and security risk be present.It is that is, because long-term
It is insufficient to nickel-cadmium cell or Ni-MH battery electric discharge, cell degradation in emergency light and cannot shine in the event of a loss of power
, very big security risk be present in bright or instruction.
At present, capacitor, especially capacitor bank can meet the needs of interim electric discharge power supply.And capacitor bank for
Technology on the control quantity of electric charge has tended to be ripe.Effective discharge and recharge number of capacitor is more, than nickel-cadmium cell or ni-mh
The charge and discharge cycles of battery are more reliable.But the capacity of capacitor can not directly meet the needs of light fixture.Moreover, charging
Do not limited with the process of electric discharge, it is all unfavorable for application that electric charge, which largely enters and released,.
More, traditional emergency light needs regularly to carry out functional test.To emergency light or the capacitance module of inside
Carry out manual inspection, the validity of assurance function.But not only labor intensive cost, but also meeting is regularly checked manually
In the presence of many factors of instability.For example, just having there is the problem of capacitance module aging before an examination, could not timely change
Etc..More, because destabilizing factor many in circuit, the feelings put are overcharged and cross to having in the use of capacitance module
Condition, this all has harmful effect to the service life of capacitance module.So, power failure telegram in reply how is overcome to the electric capacity mould in emergency light

According to detection of the detection module 31 for civil power situation, the control module 32 judges whether to need the electricity
Container group 220 is powered.When city's electrical anomaly, such as have a power failure, electric voltage exception is fluctuated, it is necessary to which the capacitor bank 220 is peremptorily
The lamp body 10 is powered.The control module 32 is changed the capacitance module 22 and powered into the lamp body 10.The detection module
The discharge scenario of 31 pairs of capacitor banks 220 monitors in real time.Until discharge voltage reaches certain threshold value, then foundation civil power situation
Determine whether, in switching power supply source is needed, to ensure being substantially discharged for the capacitor bank 220.That is, in the electricity
During container 220 discharges, civil power is just detected in real time, continues to be discharged to completion according to the capacitor bank 220,
The civil power for having switched to recovered again.
More, in the method for supplying power in this preferred embodiment, the processing and control element (PCE) 30 can be realized to institute
State the Autonomous test of capacitor bank 220.By detection of the detection module 31 to the situation of capacitor bank 220, and can be right
The detection of charge and discharge circuit, control by the control module 32 are carried out.The detection module 31 is to the capacitor
220 voltages of group, charging current and charging voltage are acquired, and the control module 32 decides whether according to certain cycle
Tested.Autonomous test is completed according to the circuit pattern in Fig. 5, then controls the AC/DC in the civil power module 21 to change
Contactor is in open circuit, charge management circuit does not work, inverter circuit work, the capacitances to supply power of the control module 32 and drive
The capacitance module 22 that dynamic power supply conversion is switched in said supply unit 20 supplies electricity to the LED lamp of the lamp body 110.It is described
Detection module 31, which coordinates, is verified the validity that the capacitance module 22 is in emergency circumstances powered.Certainly, the power supply
The execution cycle of the Autonomous test of method can artificially set, and can also be performed according to the state of the capacitor bank 220.
For example, the checking that every three months energize reliability can be set.For example, be able to may be had according to the capacitor bank 220
The testing result of damage, it is irregular to carry out energy supply checking.
The being controlled property of supply line is selected by the control module 32, to filling for the capacitor bank 220
Electricity and electric discharge manage with carrying out maintainability, and then ensure the use reliability of the capacitor bank 220 so that the emergency light
Using with certain stability.Preferably, the detection module 31 and the control module 32 cooperate to the electric capacity
The working environment of device group 220 provides the processing of unscheduled maintenance, avoids overcharging or putting excessively for the capacitor bank 220, subtracts
Harmful effect caused by the unstable power supply of few capacitor bank 220.For example, when the capacitor bank 220 charges pair
Every group of the capacitor bank 220 evenly distributes suitable electric current and charged, and ensures the charging of each capacitor bank 220
Time is equal, and capacity is consistent.When the capacitor bank 220 is discharged, ensure that external discharge time is consistent, electric current is consistent.According to
Need, the control module 32 carries out periodic functional test to the capacitor bank 220, ensures the capacitor bank 220
It can be that the lamp body 10 provides the energy under emergency conditions, improve the reliability of the capacitor emergency light.The detection mould
Block 31 detects to the charging and discharging of electric power thus supplied and the capacitor bank 220, collects data and by the communication module
33 pairs of external feedbacks, the luminous power supply in the case of emergent is effectively controlled.
Other side under this invention, the present invention further provides the method for supplying power to of a capacitor emergency light, including such as
Lower step：
