Fig. 2 is standby electric member on printing distributing board 109 and function square 200 schematic diagrames of assembly of being loaded in the present embodiment.Moreover, as assembly system identical with Fig. 1 as rechargeable battery is used the symbol identical with Fig. 1.Sequentially from Fig. 2 left-hand side, describe, first city is to be directed into direct current converter section 202 from the joint 103 of LED lighting device 100 with power line.Direct current converter section 202 is the commutating circuit that comprises transformer, transistor etc., in order to convert city to direct current in predetermined or setting range with the alternating current of power supply.The output of direct current converter section 202 is to be directed into switch portion 201 afterwards.
Switch portion 201 assembly that possesses startup, closes the output of voltage comparing section 205 as described below.At least can the light a lamp switching of pattern and charge mode of the switch portion 201 of the present embodiment, if switch portion 201 when lighting a lamp pattern (being connected with the contact of graphic middle upside), city is to be directed into DC-DC converter section 203 with the alternating current of power supply.DC-DC converter section 203 is the driving voltage that generates driving LED array 208 use, and the LED drive current of operating voltage/controlling resistance being given by controlling resistance 204 is supplied to LED array 208, lights by this LED lighting device.In the pattern of lighting a lamp and electric light pattern, in order to charge to rechargeable battery 110 in the time that LED lighting device 100 is lit a lamp, the output of direct current converter section 202 is also supplied to charging control section 207.Moreover as shown in Figure 1, a LED array 208 coefficients LED105 is equipped on the array shape light source on printing distributing board 109.
On the other hand, if switch portion 201 is connected to the below in graphic, become electric light pattern, and city is circulated to charging control section 207 with power supply alternating voltage system.Charging control section 207 is to use its direct current of predetermined voltage receiving to control rechargeable battery 110 its chargings.Moreover, if charging control section 207 is controlled in and determines voltage, determines under electric current, be generation predetermined charge voltages, can control to avoid producing and overcharge etc.
The output system of charging control section 207 is supplied to rechargeable battery 110, and lies in when rechargeable battery is charged and use in the embodiment of explanation.Separately, the charging voltage system that charging control section 207 is exported inputs to voltage comparing section 205, is to judge opening circuit of city's power supply.Moreover as mentioned above, being output under the pattern of lighting a lamp and electric light pattern of direct current converter section 202, can be simultaneously for giving charging control section 207 and by city's power supply, rechargeable battery being charged.By this, can often charge to rechargeable battery 110, therefore more can really guarantee that in Emergency time LED drives electric power.
On the other hand, voltage comparing section 205 is connected with the output of rechargeable battery 110.Voltage comparing section 205 compares the voltage of charging voltage and rechargeable battery 110, and controls the drive current of the rechargeable battery 110 that is supplied to LED array 208.
Then the function of account for voltage comparing section 205, voltage comparing section 205 is comparison charging voltage (V
in) with the output voltage (V of rechargeable battery 110
ref), and in the output voltage V of rechargeable battery 110
refwhen higher, be judged as in non-charging.Separately, if voltage comparing section 205 judges V
inhigher than V
reftime, be judged as in charging or by city and use in power supply point lamp.Therefore, in for charging or while using the situation in power supply point lamp by city, output is set as to OFF(Low level), and the drive current that does not make rechargeable battery 110 export is supplied to LED array 208.
On the other hand, if V
refhigher, while using power supply in non-charging and without supply city, voltage comparing section 205 is output driving LED array 208 necessary driving voltages.The output voltage system of voltage comparing section 205 is delivered to second switch portion 209, and second switch portion 209 is except startup while using flashlight etc. being provided under the pattern of lighting a lamp, closing handoff functionality, separately under the electric light pattern of the present embodiment, use when moving LED lighting device 100.
Though second switch portion 209 can be shared Switch structure with switch portion 201, in specific embodiment, also can be other diverter switch and arrange in addition.More specifically prescribed voltage comparing section 205 and second switch portion 209 functions.If be judged as in non-charging, voltage comparing section 205 is the driving voltage of generation driving LED array 208 described above.The driving voltage system generating puts in second switch portion 209, if (close second switch portion 209) under electric light pattern, LED lighting device 100 has the pattern that replaces incandescent lamp function.Therefore, the driving voltage that rechargeable battery 110 is exported there is no and is supplied to LED array 208, so cannot make LED array 208 luminous.
On the other hand, mooring points lamp pattern in the time that second switch portion 209 starts, if detect city's power supply open circuit and non-charging in time, generate the driving voltage of driving LED array 208 use.The driving voltage generating is applied to second switch portion 209, and now because being the pattern of lighting a lamp, the driving voltage system that self-charging battery 110 is exported is supplied to LED array 208, makes LED array 208 luminous.
This state, under the pattern of lighting a lamp, in the time that LED lighting device 100 is connected to city and uses power connection, becomes the state as emergency lamp function.Separately, when LED lighting device 100 is after joint removes, make rechargeable battery as power supply and become, the state that LED lighting device 100 is moved as flashlight.
The driving voltage that is applied to second switch portion 209 is applied to LED array 208 via controlling resistance 204, the LED drive current system that operation voltage/controlling resistance is given is supplied to LED array 208, and LED lighting device is lighted.Moreover, controlling resistance 204 is relevant to the controlling resistance that is connected to DC-DC converter section 203 and can be identical or different with being connected to the controlling resistance of second switch portion 209, its object is to extend the operate time while driving with rechargeable battery 110, is therefore set to maximum resistance value compared with good system in response to the object of flashlight and emergency lamp.
Fig. 3 is the embodiment schematic diagram of voltage comparing section 205 its voltage comparison loop 300 of the present invention.Voltage comparison loop 300 can be the structure that comprises comparator 301, and operation voltage uses the output voltage of rechargeable battery 110, when being convenient to city and using electric power disconnection, also can successfully move by the rated output voltage of rechargeable battery 110.Separately, comparator 301 is counter-rotative type comparator configuration, and its negative input terminal (–) is with being input voltage, and positive input terminal (+) is with being reference voltage.
On the other hand, in negative input terminal (–), charging voltage (V
in) input by resistance 302, and in positive input terminal (+), be rechargeable battery 110 voltage (V
ref) input by resistance 304.Because comparator 301 is counter-rotative type comparator, work as V
in≤ V
reftime, be output as and close (Low Level), and work as V
in<V
reftime, output (rechargeable battery output voltage) starts, and the voltage that output equates with rechargeable battery 110 voltages.Moreover, 305 of the resistance that are connected with the lead-out terminal of comparator 301 on draw (Pull-up) resistance.
,, when charging voltage is, while having the meaningful numerical value that exceeds 0V, to be expressed as in charging, the charging voltage in charging is because of more than being at least the output voltage of rechargeable battery 110, therefore can not block city's power supply.Now, because supplying with electric power by self-charging battery 110, by the reversion judged result of comparator 301, comparator 301 becomes output closed condition.On the other hand, when charging voltage is 0V, 100 of LED lighting devices have following arbitrary state, and meet V simultaneously
in<V
ref: (1) city becomes power down mode with power supply; (2) user closes manipulation of switches state; (3) use as flashlight.
Now, while wanting to use as flashlight or emergency lamp, if without rechargeable battery 110 supply with electric power LED lighting device 100 cannot play a role, therefore comparator 301 is start output and generate and the voltage (V of rechargeable battery 110 in its outlet side terminal
ref) equal output voltage.If user sets second switch portion 209, charging voltage (V in response to its object
ineven if) presenting user and indicate the state of above-mentioned (2) of light-off, the electric power that rechargeable battery also can not carry out is for no reason supplied with, so rechargeable battery 110 does not have consumption.
On the other hand, in the situation of this above-mentioned (1) and (3), user starts after second switch portion 209, comparator 301 in its lead-out terminal by the voltage (V of rechargeable battery 110
ref) output, the therefore maximum Limited Current that can be supplied to comparator 301.In most cases, LED array 208, for moving 20mA left and right, therefore, if comparator 301 uses as power amplifier, can be applicable to be equipped with the large LED lighting device of most LED105.Another in response to necessary output current, can be in comparator 301 outlet side configuration transistors to strengthen output current.
Moreover, when switch portion 201 is set as charge mode, can, simultaneously by closing the switching mechanism of second switch portion 209, under charge mode, give LED array 208, the action of charging more efficiently by this without supplying with drive current.More in other embodiment, can form contacts in extension 112 upper ends, also form contacts in framework 101 enlarged portion downsides, to form the second switch portion 209 that starts, closes in response to its knee-action of those contacts or spinning movement.By this, in response to the use state of electric light, emergency lamp and flashlight, user is by switching second switch portion 209, and can the corresponding various actions of lighting a lamp.
By using above-mentioned voltage comparing section 205, LED lighting device 100 can be used as electric light, flashlight and emergency lamp and uses.
Fig. 4 is the second embodiment that shows LED lighting device 100 function squares.Moreover the assembly system identical with function shown in Fig. 2 marks with same-sign.In embodiment illustrated in fig. 4, the direct current converter section 202 of Fig. 2 is separated into direct current converter section 202a, the 202b of 2 series, separately in order to bring into play light a lamp pattern, electric light pattern and charge mode.
The deviation of corresponding this structure, directly input with power supply in switch portion 201Xi You city, if while being connected to graphic middle upside contact, LED lighting device 400 is brought into play pattern and the electric light pattern of lighting a lamp, if while being connected to graphic middle downside contact, can be under charge mode driving LED lighting device 400.In embodiment illustrated in fig. 4, voltage comparing section 205 is comparison charging voltage and rechargeable battery 110 its output voltages, and applies LED array 208 its driving voltages of rechargeable battery 110 sides in response to comparative result.
Fig. 5 system is by the output voltage V of action corresponding to comparator 301 of lighting a lamp of the charging action of the present embodiment, LED array 208
outkey diagram.The charging electric of LED lighting device 100 carries out while lighting a lamp with the energising of power supply as the charging in the time buying and city.The electric power system that self-charging battery 110 is supplied with during this period wastes.The present embodiment LED lighting device 100, it has a switching mechanism, this switching mechanism by city with power supply as lit a lamp as usually time, system charges to rechargeable battery simultaneously, therefore also can in the time buying, do not driven with charge mode, and while charging under charge mode, as above-mentioned, in the time that switch portion 201 is set to charge mode, second switch portion 209, through related and be closed, avoids carrying out the charging of rechargeable battery 110 in the time that LED array 208 is switched on by this switching mechanism.Moreover, be convenient to switching mechanism above-mentioned state occurs, do not affect the charged state of the pattern of lighting a lamp, therefore in fact without bringing inconvenience.
For example, the rechargeable battery of lithium ion battery, its rated output voltage is 3.7～3.8V, voltage reduces with electric discharge.On the other hand, charging action most of in the initial stage system by being at least that more than the output voltage of rechargeable battery charging voltage Vin carries out constant-current charge action, then carry out the constant-voltage charge of 4.1～4.2V, and invest the output voltage V of rechargeable battery
outwith V
refidentical numerical value.In embodiment shown in Fig. 5, in Fig. 5 (a) start to charge time, charging voltage V
insystem rises to V immediately
ref, therefore comparator 301 output voltage V

refcondition, so as shown in Fig. 5 (b), the output voltage of comparator 301 system moves to V
refstate.The action of this complete charge can be taken off with power supply from LED lighting device 100 city by diverter switch portion 201, by it and the timer of charge closing control part 207 etc. or blocking-up city power supply.Now, if close second switch portion 209, LED array 208 can not be lighted.Moreover this state is equivalent to flashlight pattern or electric light pattern.Under this state, if user is without deliberately operating second switch portion 209, LED array 208 can not be lighted and be extinguished.
Separately, during as emergency lamp, user need deliberately activate second switch portion 209.Under this state, in the time that charging voltage is 0V, system is applied to the driving voltage of rechargeable battery 110 LED array 208 immediately to light LED array 208, lights LED lighting device 100 when being opened circuit suddenly in the electricity consumption source of going on the market.Separately in other embodiment, if while use as emergency lamp, system connects extension 112 and enlarged portion in advance, while grade in having a power failure by this, bring into play the function of emergency lamp, if during without performance emergency lamp function, do not need to connect extension 112 and directly use with enlarged portion, can control and light a lamp more efficiently.
Fig. 6 is the functional block diagram of second embodiment of the present embodiment.Indoor illumination major part lies in the structure of lighting the lamp of low electric weight while light-off in order to indicate the position of the switch.In the second embodiment, when performance indoor illumination function, provide the function of automatically lighting a lamp while power failure., in Fig. 6, about direct current converter section 601, charging control section 602, DC-DC converter section 603, rechargeable battery 605 and LED array 610, be separately with identical described in the first embodiment.
In the second embodiment of Fig. 6, the voltage comparing section 604 of change in voltage when it comprises relatively to have a power failure, be judged as the power failure that can automatically light a lamp while power failure the light a lamp part in loop 608 of portion 606 and LED of automatically lighting a lamp and be different from the LED lighting device 100 shown in the first embodiment.Voltage comparing section 604 is voltage comparing component, with comparison detection voltage and charging voltage or detecting voltage and earthed voltage that rechargeable battery 110 is charged.
LED lighting device 610 its users use to be installed on being commonly called as fluorescent switch 611 is to control lighting a lamp of LED lighting device 610 of wall etc.Fluorescent switch 611 possesses the function of lighting a lamp under illumination body switch closed condition and extinguish after starting switch, is the structure that comprises the luminescence component such as internal resistance and LED (fluorescent lamp).When fluorescent switch 611 is OFF, electric current is via left-hand side path circulation in Fig. 6, and while being ON, electric current system is via right-hand side path circulation in Fig. 6.Though fluorescent switch 611 has weak current circulation while being OFF, be not enough to drive DC-DC converter section 603, so that cannot light LED.
Separately, LED lighting device 600 cordings are standby shows that fluorescent switch 611 is the fluorescence current potential generating unit 612 of closed condition.Moreover though the current potential of fluorescence shown in Fig. 6 generating unit 612 only lists most basic structure, without many speeches, it also can be used as in addition structure dress of the module such as plate body, IC.Fluorescence current potential generating unit 612 is to be made up of diode (also can be the diode bridge (diodebridge) of full-wave rectification), capacitor etc., system's circulation low current in the time that fluorescent switch 611 is OFF state, and fluorescent lamp bulb is position luminous and display switch.
Now, if with LED composition fluorescent lamp, number mA approximately circulates.Now, fluorescence current potential generating unit 612 cordings are for the capacitor of capacity C, and till the current potential of this capacitor after by divider resistance dividing potential drop roughly charge to the charge Q of relation as shown in following formula (1).
[formula 1]
Q＝∫CV(t)dt (1)
In this formula, V (t) is the current potential that puts on fluorescence voltage generating unit 612 its current capacity (capacitance) upstream sides, and its capacitor current potential of following formula (2) is fluorescence current potential HV.
[formula 2]
HV＝Q/C (2)
This fluorescence current potential HV is during the common start of LED lighting device 600, and no matter whether fluorescent lamp is lighted, and all applies fixing fluorescence current potential HV, provides and shows that city power supply VAC is for the normal current potential of surveying.This detection current potential system inputs to voltage comparing section 604.In the time of power failure time control stop electricity, automatically light a lamp portion 606 to switch to the supply access of LED array 610.By this, LED array 610 is luminous, makes the present embodiment LED lighting device 600 bring into play emergency lamp function.
Fig. 7 is the voltage comparing section 604 of the present embodiment and the loop structure example of the electric portion 606 of automatically lighting a lamp.The fluorescence current potential generating in order to light the weak current of luminescence component of the identification position of the switch when detecting voltage system is the output voltage of rechargeable battery or switch OFF.The fluorescence current potential HV system of detecting voltage respectively inputs by divider resistance via two OR locks.When fluorescence current potential (detection current potential) HV possesses the city power supply of demonstration and is normal current potential, OR lock 701 is to assert that (assert) is in L, if when fluorescence current potential HV is power failure current potential (as: earthing potential), assert in H, and those are all driven through rechargeable battery.
Automatically the portion 606 of lighting a lamp when power failure can be the composition that comprises transistor 703, inverter 704 and FET705.When fluorescence current potential HV is normal current potential, transistor 703 is OFF, and the LED loop 608 that lights a lamp is to receive the electric power that DC-DC converter section 603 is supplied with.Now, fluorescence current potential HV itself does not drive DC-DC converter section 603, and therefore DC-DC converter section 603, LED lamp circuit 608 do not produce action, causes LED array 610 also without bright light.
Separately, in the time having a power failure, react on and the comparison of detecting voltage, transistor 703 is set as ON.Result causes FET705 to close, and LED loop 608 self-charging batteries 605 of lighting a lamp are accepted electric power and supplied with, and LED array 610 will be lighted as emergency lamp.Separately, the switch 607 of the present embodiment ties up to the switch of bringing into play flashlight function in the time that joint takes off LED lighting device 600.During as indoor lamp or emergency lamp, be connection status if closing switch 607 is closed circuit, when normal with power supply in city, by the effect of fluorescence current potential HV, self-charging battery 605 is not supplied with electric power, but makes LED array 610 luminous by supplying with electric power from city with power supply.In addition, in the time having a power failure, city uses power supply without supplying with electric current, separately by the power failure of the fluorescence current potential HV automatic control of portion 606 in the time having a power failure of automatically lighting a lamp, self-charging battery 605 starts to supply with electric power, therefore all supply with without receiving electric power from both sides supply passageway, so can smooth and easy switching indoor lamp and emergency lamp two functions.
Fig. 8 is the state of lighting a lamp that arranges out the LED lighting device of the second embodiment.In the second embodiment, the state of LED lighting device exists three kinds, the action of light a lamp when (closing fluorescent switch) turned off the light (×), had a power failure when now the luminance of LED array 610 is lit a lamp (zero), turned off the light in the time lighting a lamp (zero).Therefore, when electricity failure at night or in tunnel, when the loss of power such as shopping street, it can be taken off and diverter switch from joint, use as flashlight immediately by this, thereby be convenient for carrying.Separately, by the present invention, be in the time having a power failure, (while stopping with power supply in city) no matter LED lighting device is the light a lamp/non-state of lighting a lamp, all can put the LED of bright light source.Therefore, by lighting LED, just can learn and have a power failure, therefore can appropriateness prepare to carry out the switching of emergency lamp etc.
As previously discussed, the present invention system provides a kind of LED lighting device and lighting control method thereof, can replace immediately conventional incandescent and in the time having a power failure, automatically bring into play emergency lamp function, more can bring into play portable electric light function.Moreover, that the LED lighting device of the present embodiment is not limited to is home-use, leisure use, also can stop with power supply because of city temporarily in possibility such as undergrond street, tube, tunnel, subway, airfield runway, helidromes and cause the lighting device use as low consumption electric power in the building of puzzlement or works.
