When forming the external dimmer signal by the control signal of carrying out the conducting operating time according to the mode of general employing, the conducting operating time is 0%, and then the signal of telecommunication of external dimmer signal is 0 level.At this moment external dimmer signal reaches and does not have other state of external dimmer signal time zone for being difficult to.When this state, be not easy to discern the external dimmer signal, thereby under this situation, such as mentioned, preestablish microcomputer, so that be not identified as the external dimmer signal more than the signal of telecommunication not being comprised the minimum levels of 0 level.
Like this, among the present invention owing to utilize external signal to carry out the switching that initial stage illumination is proofreaied and correct control ignition mode and external control light modulation ignition mode, in the time of doing forming apparatus on the structure and import and equipment all can carry out above-mentioned switching the arbitrary period after importing.
When the external dimmer signal is used as external signal, dimmer for example is contained on the metope and makes between the light modulation terminal of dimmer and fluorescent lamp lighting apparatus and be connected with the external dimmer line, and operate this dimmer, the microcomputer of then controlling usefulness detects the external dimmer signal and supplies with the situation of adjusting control circuit and be controlled to initial stage illumination correction control circuit inoperative through the external dimmer line, thereby the microcomputer of control usefulness works as switch unit, carries out proofreading and correct the switching of control ignition mode to external control light modulation ignition mode from initial stage illumination.Therefore, fluorescent lamp lighting apparatus is set after, when fluorescent lamp lighting apparatus detects less than the external dimmer signal, initial start stage illumination correction control circuit automatically, the initial stage illumination of carrying out on the fluorescent lamp lighting apparatus monomer is proofreaied and correct control.
The light modulation of external dimmer signal can the person of being to use makes any in the fixing light modulation of illumination after light modulation, the initial stage illumination of operation are proofreaied and correct the light modulation of control usefulness and for example detected ambient light arbitrarily.
The fluorescent lamp lighting apparatus of the present invention the 3rd aspect, be aspect the present invention the 1st or the 2nd in the described fluorescent lamp lighting apparatus, switch unit is structurally made when formality makes on/off according to the rules, fluorescent lamp is switched to initial stage illumination proofread and correct the either party who controls in ignition mode and the external control light modulation ignition mode.
The invention provides and switch structure that ignition mode uses and easy to operate state.Promptly, fluorescent lamp lighting apparatus is being provided with afterwards or the desirable time after bringing into use, formality according to the rules makes its power supply, continuous 3 break-makes of for example AC power, and fluorescent lamp lighting apparatus is when detecting this break-make, with ignition mode from theretofore mode switch to another pattern.For example be that initial stage illumination is proofreaied and correct when controlling ignition mode, utilize aforesaid operations to switch to external control light modulation ignition mode.Equally, when being external control light modulation ignition mode, utilizing aforesaid operations to switch to initial stage illumination and proofread and correct the control ignition mode.The afore mentioned rules formality not only can be stipulated the number of times of switching, and can be defined as the relation of defined the time interval of switching.
In accordance with regulations whether the formality judgement of carrying out on/off can be carried out as follows.That is, for example make the microcomputer of control usefulness store the program of judging usefulness in advance, and carry out the comparison operation with detected make-and-break signal, thereby can make things convenient for and judge reliably, and according to its initial start stage illumination correction control circuit as a result.
Can be when formality make on/off in accordance with regulations, make the also break-make in linkage of power supply (Vdd) of the microcomputer of control usefulness, also can structurally make the power supply (Vdd) that makes microcomputer and keep conducting state between the time continuously at defined.In order to realize this point, can pre-configured storage battery and the back-up source of charging with compositions such as capacitors.
Also can be as indicated above, initial stage illumination correction control ignition mode and external control light modulation ignition mode are set up mark respectively, and store microcomputer into.
Like this, among the present invention, do not do special treatment when being provided with, carry out common construction, operating power switch only after the configuration just can switch to operating state with initial stage illumination correction control circuit, its processing ease, and structure is also simple simultaneously.
The fluorescent lamp lighting apparatus of the present invention the 4th aspect, be aspect the present invention the 1st in, switch unit is made up of console switch.
The invention provides switch unit simple in structure.That is, by console switch is operated, select initial stage illumination to proofread and correct control ignition mode or external control light modulation ignition mode, thereby can be regardless of and have non-transformer ground to carry out this operation.Console switch can be contained in fluorescent lamp lighting apparatus or the lighting.
Like this, among the present invention, the operation of console switch can be carried out before the lighting installation, after the construction, also can carry out before energized.Also can be according to required, switch to construction after.And, can obtain this console switch more at an easy rate.
The present invention the 5th aspect, be in the present invention the 1st to 4 in the described fluorescent lamp lighting apparatus of either side, when switch unit is structurally made high frequency points brightening circuit no-load condition, fluorescent lamp can be switched to initial stage illumination and proofread and correct the either party who controls in ignition mode and the external control light modulation ignition mode.
The present invention's regulation can be set for the ignition mode of the partial illumination light fixture in the illuminated space different with the pattern of all the other lightings.That is, fluorescent lamp is contained on the lighting, then fluorescent lamp connects the high frequency points brightening circuit, thereby from the high frequency points brightening circuit, is exactly load condition.Otherwise, when lighting unloads fluorescent lamp,, then become no-load condition from the high frequency points brightening circuit.Among the present invention, only when the high frequency points brightening circuit is no-load condition, can switch the illuminating state of fluorescent lamp.
So, only the fluorescent lamp lighting apparatus that will switch ignition mode is unloaded fluorescent lamp, be non-loaded.The fluorescent lamp that does not need to switch then still installs constant.Then, for example supply with the external dimmer signal, carry out handover operation simultaneously by fluorescent lamp lighting apparatus to whole illuminated space.As a result, only the fluorescent lamp lighting apparatus with no-load condition for example switches to external dimmer control ignition mode, remaining fluorescent lamp lighting apparatus is not switched.
Therefore, the present invention for example especially is fit to make on the structure by whole illuminated space and like that a plurality of fluorescent lamp lighting apparatus is for example supplied with the external dimmer signal the situation that can switch ignition mode simultaneously such as to switch.Yet, even under the situation of switching the monomer fluorescence lamp igniting device, feeling like doing precedent and do not carry out ignition mode as not noting when switching, the present invention is also effective.

Therefore, in the above-mentioned last structure, often carry out initial stage illumination and proofread and correct control, no matter have or not external dimmer control.The illumination that not only arbitrary ignition mode is all often kept the full light time of fluorescent lamp (being that light modulation is than 100%) is constant, and also makes the relation of light modulation degree and illumination keep constant during external dimmer.
Otherwise, under one situation of above-mentioned back, carry out initial stage illumination when only illumination is proofreaied and correct the control ignition mode in the early stage and proofread and correct control, do not carry out initial stage illumination during external control light modulation ignition mode and proofread and correct control.Therefore, fluorescent lamp in the full light time, be whole abilities that the illumination of light modulation than 100% o'clock can use fluorescent lamp at this moment to have, thereby can bring up to maximal illumination.Yet, after the external control light modulation ignition mode, switching to initial stage illumination again proofreaies and correct when controlling ignition mode, because the time of lighting in the external control light modulation ignition mode is added to initial stage illumination and proofreaies and correct in the cumulative time of control, also carry out initial stage illumination correction in the time with lighting in the external control light modulation ignition mode and control identical; Illumination when being transformed into initial stage illumination correction control ignition mode once more is with identical in the past.
Like this, among the present invention,, after fluorescent lamp is transformed into external control light modulation ignition mode halfway, returns initial stage illumination once more and proofread and correct when controlling ignition mode, also can carry out the constant illumination of illumination owing to have said structure.
The fluorescent lamp lighting apparatus of the 1st to 6 aspect according to the present invention, owing to can proofread and correct any that control in ignition mode and the external control light modulation ignition mode with switch unit selection and the initial stage of setting illumination, under situations such as setting and use, can select the ignition mode of wishing.
Therefore, the changed condition of not only being convenient to follow the lighting installation system to change after being provided with is finished renew bright lamp tool and/or fluorescent lamp lighting apparatus, and does not cause the quantity of product type to increase, and makes production management, stock control and sales management convenient.
The 2nd aspect according to the present invention, also structurally make switch unit when detecting external signal, switch to initial stage illumination and proofread and correct either party in control ignition mode and the external control light modulation ignition mode, therefore switch that ignition mode uses relatively simple for structure and fluorescent lamp lighting apparatus that it is easy to operate can be provided.
The 3rd aspect according to the present invention is also structurally made when formality makes on/off in accordance with regulations, fluorescent lamp is switched to initial stage illumination proofread and correct the either party who controls in ignition mode and the external control light modulation ignition mode.Therefore the fluorescent lamp lighting apparatus simple in structure of switch unit can be provided.
The 4th aspect according to the present invention also makes switch unit be made up of console switch, thereby can provide switch unit simple fluorescent lamp lighting apparatus.
The 5th aspect according to the present invention, also structurally make switch unit when Frequency point brightening circuit no-load condition, fluorescent lamp can be switched to initial stage illumination and proofread and correct the either party of control ignition mode and external control light modulation ignition mode, therefore the fluorescent lamp lighting apparatus that can be only the ignition mode of the partial illumination light fixture in illuminated space be switched can be provided.
The 6th aspect according to the present invention, when also structurally making initial stage illumination correction control circuit and externally controlling the light modulation ignition mode and light, also proceed fluorescent lamp accumulative total and light the timing of time, therefore can provide and return initial stage also identical fluorescent lamp lighting apparatus of illumination during the illumination correction mode once more.

Fig. 2 to Fig. 4 illustrates the mode 2 that fluorescent lamp lighting apparatus of the present invention is used of implementing, Fig. 2 is a circuit block diagram, Fig. 3 is the flow chart of switch unit when switching running, Fig. 4 is the oscillogram of relation that the waveform of on/off waveform and microcomputer supply voltage Vdd is shown, and the manner is structurally made the output control switch unit SM by on/off regulation formality testing circuit OND.
On/off regulation formality testing circuit OND and switch unit SM are made up of the microcomputer of the control of administering fluorescent lamp lighting apparatus, finish when switching cooperating with each other, and carry out the running shown in the flow chart of Fig. 3.
That is, in microcomputer inside initial stage illumination correction control ignition mode and external control light modulation ignition mode are set up mark in advance, and stored.So when switching ignition mode, after initialization, at first the verification status indication is any pattern to discern current ignition mode.
Secondly, the state of verification low-frequency ac power AC.This verification judges whether energized by low-frequency ac power AC conducting or blocking-up.If connect low-frequency ac power AC, proceed to next judgement.During access failure low-frequency ac power AC, the change status indication, thereby do not carry out the switching of ignition mode.In the manner, shown in Fig. 4 (b), apply the supply voltage of microcomputer continuously, thereby microcomputer is worked also during access failure low-frequency ac power AC from back-up source.
Then, microcomputer judges that the break-make number of times of low-frequency ac power AC is whether more than the stipulated number.During this judged, the break-make number of times of low-frequency ac power AC was equivalent to rectification and the number count of the interrupted waveform after being transformed into direct voltage shown in Fig. 4 (a).
Then, if the break-make number of times of low-frequency ac power AC is more than the stipulated number, the change status indication, thereby change ignition mode.For example, when low-frequency ac power break-make regulation formality testing circuit OND detected the on/off of regulation formality, making initial stage illumination correction control circuit ICC was operating state.
Otherwise above-mentioned break-make number of times is less than stipulated number, does not then change status indication.And microcomputer repeats the whether above judgement of stipulated number of break-make number of times of low-frequency ac power AC again.
Fig. 5 and Fig. 6 illustrate the mode 3 that fluorescent lamp lighting apparatus of the present invention is used of implementing, and Fig. 5 is the flow chart of switch unit when switching running, and Fig. 6 is the oscillogram of relation that the supply voltage Vdd of on/off waveform and microcomputer is shown.The difference of the manner and mode 2 is: make fluorescent lamp lighting apparatus on the structure and can change ignition mode when non-loaded.Below the different part of explanation and mode 2 only.
That is, after initialization and status check, verification has non-loaded.If fluorescent lamp lighting apparatus is a load condition, the change status indication does not switch thereby do not carry out ignition mode.Be no-load condition, whether the break-make number of times of then judging next low-frequency ac power AC is more than the stipulated number.Thereafter identical with mode 2.
In the manner, shown in Fig. 6 (b), form the supply voltage Vdd of microcomputer according to the voltage of low-frequency ac power AC, thereby Vdd becomes the voltage synchronous with the break-make of low-frequency ac power AC.Fig. 6 (a) illustrates the waveform of the low-frequency ac power voltage after the rectification.
Fig. 7 and Fig. 8 illustrate and implement the mode 4 that fluorescent lamp lighting apparatus of the present invention is used, and the circuit block diagram of the fluorescent lamp lighting apparatus when Fig. 7 is external control light modulation ignition mode, Fig. 8 illustrate some external dimmer signal waveforms.The manner is the fluorescent lamp lighting apparatus when being fit to external control light modulation ignition mode.Among Fig. 7, symbol l D is the light modulation line, and SW is a mains switch, and t a, t b are power input terminal, and t c, t d are the high frequency lead-out terminal, and t D is the light modulation terminal.
That is, fluorescent lamp lighting apparatus FOC has power input terminal t a and t b, high frequency lead-out terminal t c and t d and light modulation terminal t D.Power input terminal t a provides mains switch SW to be connected low-frequency ac power AC with t b.High frequency lead-out terminal t c is connected fluorescent lamp FL with t d.Light modulation terminal t D connects the end of light modulation line l D.
The other end of light modulation line l D connects the dimmer as external dimmer signal generating circuit ODS.As shown in Figure 8, the external dimmer signal was made up of than the voltage that changes with light modulation the operating time.
Fig. 8 (a) for light modulation than 100%, Fig. 8 (b) for light modulation than 50%, Fig. 8 (c) for light modulation than 5%, Fig. 8 (d) for light modulation than 0%.In the manner, light modulation is than the degree of lighting that fluorescent lamp FL is shown, and light modulation means that than 100% o'clock 100% lights, and light modulation meaned than 0% o'clock and do not form the external dimmer signal, meaned that also fluorescent lamp extinguishes simultaneously.With fluorescent lamp FL continuous light tuning to 0%, be actually difficulty, thereby the light modulation ratio of minimum level can be taken as 5%.
In the manner, make on the structure if the external dimmer signal that arrives the light modulation terminal for the minimum level light modulation than more than, switch unit is just discerned the external dimmer signal, and ignition mode is switched to external control light modulation ignition mode.
Fig. 9 illustrates the circuit block diagram of implementing the mode 5 that fluorescent lamp lighting apparatus of the present invention uses.The switch unit SM of the manner is made of console switch.In fluorescent lamp lighting apparatus or unshowned lighting, set up switch unit SM, operate this unit from the outside by for example workmen or user.
Therefore, in the manner, the switch unit SM that in the time of can be by for example room layout change after importing at equipment and importing etc. console switch be formed operates, and switches to initial stage illumination and proofreaies and correct the control ignition mode, or switch to external control light modulation ignition mode.
The curve shows of Figure 10 is implemented the effect of the initial stage illumination correction control circuit when the initial stage of fluorescent lamp length of life illumination is proofreaied and correct control ignition mode and external control light modulation ignition mode in the mode 6 that fluorescent lamp lighting apparatus of the present invention uses.Among the figure, transverse axis is represented to add up to light the time (1000 hours), and the longitudinal axis is represented light modulation than (%), makes on the manner structure when externally controlling the light modulation ignition mode, and the timing effect of initial stage illumination correction control circuit is continued.
Below, will with accumulative total light between 0～6000 hour time be initial stage illumination proofread and correct the control ignition mode, be external control light modulation ignition mode between 6000～9000 hours, 9000 hours be once more later mode that ignition mode is controlled in initial stage illumination correction light fluorescent lamp situation as an example, the manner is described.
Among Fig. 1, fluorescent lamp FL proofreaies and correct control when lighting mode circuit with initial stage illumination, initial stage illumination correction control circuit ICC control adjusting control circuit DCC.Therefore, fluorescent lamp FL is 0 to sentence light modulation and light than 70% the time of lighting in accumulative total, and the one side light modulation increases gradually than the growth along with the cumulative time then, and one side is lighted.Therefore, accumulative total before 6000 hours circuit time during, the illumination of fluorescent lamp FL is kept constant.
If the ignition mode of fluorescent lamp FL switched to initial stage illumination and proofreaied and correct the control ignition mode when becoming 6000 hours the cumulative time.Therefore, the external dimmer signal controlling adjusting control circuit ODS that utilizes external dimmer signal generating circuit ODS to send.
When becoming external control light modulation ignition mode, can make fluorescent lamp FL be illuminated to maximum level light modulation ratio and reach 100%.In other words, do not carry out initial stage illumination in the external control light modulation ignition mode and proofread and correct control.Yet, during the external control light modulation ignition mode in, initial stage illumination correction control circuit ICC also continues accumulative total is lighted the time timing.
When if the accumulative total time of lighting of fluorescent lamp FL is 9000 hours, returns initial stage illumination once more and proofread and correct the control ignition mode.At this moment, initial stage illumination correction control circuit ICC control adjusting control circuit DCC makes formation light the light modulation ratio of 9000 hours time as accumulative total.
As a result, carry out initial stage illumination and proofread and correct control, make the accumulative total time of lighting be 0～9000 hour during proofread and correct control with initial stage illumination and light mode continuous and light.Therefore, fluorescent lamp FL is often constant with initial stage illumination correction control ignition mode illumination in lighting.
