(circuit for lamp)
(circuit structure)
Fig. 3 is the figure of the circuit that the lighting device 10 employing the ceramic metal helide lamp shown in Fig. 2 is shown.Compared with the circuit of the ceramic metal halide lamp illumination device 100 in the past of Fig. 1, difference is, is provided with excess current control unit (is also called " fuse " for luminous tube 12.）24。
As shown in Figure 3, for commercial ac power source 2, the ceramic metal helide lamp 8 shown in stabilizer 6 and Fig. 2 is connected in series.In ceramic metal helide lamp 8, luminous tube 12 and excess current control unit 24 are connected in series, and be connected in parallel the series circuit of nonlinear ceramic capacitor FEC22 and resistance Rs28, be connected in parallel resistance Rc26 equally with this series circuit.Represent that the entrance of the dotted line frame of ceramic metal helide lamp 8 is equivalent to the cap part of lamp.
About excess current control unit (fuse) 24, will be described hereinafter.
When starting, applying alternating voltage to FEC22, utilizing its characteristic, produce pulse voltage as switch element.That is, every half period produces curent change (dI/dt) sharply and produces pulse voltage.By the effect of FEC22, the high voltage pulse produced in starting circuit is from pillar 18(reference Fig. 2) be applied to luminous tube 12.Cause insulation breakdown in the inside of the luminous tube 12 being applied in high voltage pulse, produce arc discharge and luminous tube 12 is lighted.
[excess current control unit]
(lamp current and excess current control unit)
Stabilizer 6, based on choke 6a, is arranged between 1 side (commercial ac power source) and 2 sides (lamp side) and controls the electric current flowing through lamp 8.In order to make stabilizer (being specially choke) 6 miniaturizations/low price, need lamp current I to suppress little.But, as lamp current I hour, in lamp side, need to improve modulating voltage V to obtain required performance number, but when modulating voltage V too high and close to supply voltage time, oneself such as to go out at the problem to there will be lamp.
On the other hand, in lamp side, want on the contrary to improve lamp current I, but in this case, the maximization/high price of the coil of stabilizer 6 can be caused to format.
Therefore, according to the difference of the design philosophy of ceramic metal halide lamp illumination device, even identical rated lamp power P
0, also there is multiple " nominal lamp current I
0× load lamp voltage V
0combination ".Such as, for the lamp that rated lamp power is 150W, there is the lamp that load lamp voltage is 130V specification, 90V specification, 70V specification etc., correspondingly, nominal lamp current becomes the so different current value of 1.15A, 1.67A, 2.14A.
As the fuse of excess current control unit (also referred to as " fuse wire ".) 24 can be single line or the twisted wire of the good nickel, nickel alloy, nichrome etc. of operating chacteristics.In the present embodiment, Ni line is used.
Excess current control unit 24 is according to by Joule heat I
2the temperature that R causes rises and fuses.That is, what temperature rose with electric current (that is, the actual lamp current the flowing through lamp) I that flows through in fuse is square proportional.Therefore, with rated lamp power P
0for benchmark carry out regulation blow-out current value time, owing to there is multiple " nominal lamp current I corresponding with this rated lamp power
0× load lamp voltage V
0combination ", therefore there is the unfixed problem of lamp current I.Nominal lamp current I
0the current value flowing through lamp when lamp is normal condition, at nominal lamp current I
0in large lamp, the lamp current I flow through time abnormal also becomes large.
Therefore, about the operating chacteristics of fuse 24, be necessary with nominal lamp current I
0for benchmark specifies.
(characteristic of fuse)
Please refer to Fig. 4 A ~ 4C.As the characteristic of fuse 24, require to cut off instantaneously to cause luminous tube 12 to damage such excessive lamp current I.In addition, as the characteristic of fuse 24, require that the excessive lamp current I for causing luminous tube 12 to damage cuts off instantaneously, and the fluctuation maintenance lamp of general lamp current I is lighted.
At first, in order to specify the characteristic of fuse 24, obtain the minimum electric current that breaks that luminous tube 12 is broken by experiment.For this reason, the experiment of two kinds of situations has been carried out.1st is flow through overcurrent in the lamp 8 in specified shown in Fig. 4 A is lighted, and makes the experiment that luminous tube 12 breaks.2nd is flow through overcurrent in the lamp 8 of when the starting shown in Fig. 4 B (when temperature is low), makes the experiment that luminous tube 12 breaks.About each rated current each lamp by electric current, respectively 10 lamps are tested.Experiment as a result, all there occurs breaking of luminous tube between 1 ~ 2 second.In conjunction with the experimental result of Liang Zhong Zhuan Condition, obtain the minimum electric current (▲) that breaks and (enclosed data with zero in Fig. 4 A and 4B.), describe in the chart of Fig. 4 C.
Then, to maintain the mode that lamp is lighted for the fluctuation of general lamp current I, obtained in luminous tube 12 without exception, but there is the maximum normal current of the possibility flowing through luminous tube 12.The maximum current flow through in luminous tube 12 is " during starting the electric current " that flow through when the starting of lamp.This is the value close to stabilizer second short circuit electric current.In lamp specification, the maximum fluctuation of supply voltage be defined as rated supply voltage ± 6%.Therefore, 1.06 times of stabilizer second short circuit electric current are described in the graph as maximum normal current (◆).
Its result is known, as long as carry out the characteristic of regulation fuse 24 according to minimum break electric current (▲) characteristic and maximum normal current (◆).
Specifically, causing luminous tube 12 to damage the characteristic of such excessive lamp current I as cutting off instantaneously, defining the fusing limiting behaviour of the fuse corresponding with the lamp current I lower than the minimum electric current (▲) that breaks.
And, cut off instantaneously as causing luminous tube 12 to damage such excessive lamp current I, and the fluctuation for general lamp current I maintains the characteristic that lamp is lighted, as long as specify the fusing limiting behaviour of the fuse corresponding with the lamp current I lower than the minimum electric current (▲) that breaks, and regulation and the misoperation limiting behaviour higher than fuse corresponding to the lamp current I of maximum normal current (◆).
Flow through the fuse of lamp current I exceeding fusing limiting behaviour and require to possess the characteristic that instantaneous (such as lower than 1 second) fuse.This is because breaking of luminous tube occurred between 1 ~ 2 second, therefore by making fuse blows before breaking at luminous tube, breaking of luminous tube is prevented trouble before it happens.Carried out the experiment of fusing response (response) confirming fuse as a result, when flowing through certain electric current, successfully confirm exist multiple response good, i.e. instantaneous (such as lower than 1 second) fuse of fusing.
The fuse flowing through the lamp current I not reaching misoperation limiting behaviour requires to possess the characteristic do not fused for more than 60 seconds.If this is because lamp and stabilizer are normal state, then the starting current close to stabilizer second short circuit electric current can not flow through more than 60 seconds.
At this, about the actual Ni fuse that can commercially obtain, it is known that fuse by multiple manufacturer carries out investigation, according to the deviation etc. in the difference of the purity of the material of fuse, manufacture, has 4 times (4 σ) the i.e. deviation of maximum ± 20% of standard deviation.Therefore, even the fusing limiting behaviour of fuse 24 is defined as (the fusing limit+20%) also lower than the minimum electric current (▲) that breaks.Even the misoperation limiting behaviour of fuse is defined as (the misoperation limit-20%) also exceed maximum normal current (◆).
Its result, when flowing through the lamp current I of the fusing limit exceeding regulation in (formula 1), fuse 24 instantaneous fuse, luminous tube 12 can not break.
Fusing limiting behaviour: I=6.0(I
0)
0.5+ 4 ... (formula 1)
At this, I
0: nominal lamp current
I: lamp current (the actual electric current flowing through lamp)
In addition, even if flow through the lamp current I of the misoperation limit of regulation in (formula 2), the misoperation that fuse 24 fuses can not also be there is.
Misoperation limiting behaviour: I=5.2(I
0)
0.5(formula 2)
At this, I
0: nominal lamp current
I: lamp current (the actual electric current flowing through lamp)
The meaning shown in (formula 1) and (formula 2) is, such as, at nominal lamp current I
0when=2.00A, obtain I=12.5A by (formula 1) by fusing limiting behaviour.Possess following feature: when flowing through lamp current (electric current more than I=12.5A) that exceed this fusing limiting behaviour, this fuse 24 instantaneous (such as lower than 1 second) fuses.
In addition, I=7.4A is obtained by (formula 2) by misoperation limiting behaviour.Possesses following characteristic: even if flow through the lamp current (electric current less than I=7.4A) not reaching this misoperation limiting behaviour, fuse 24 can keep more than 60 seconds and not fuse, and its result can not fuse.
In region (that is, the scope of lamp current I=12.5 ~ 7.4A) between (formula 1) and (formula 2), for the characteristic of fuse 24, do not specify especially.
In addition, for for reference, (the fusing limit+20%) and (the misoperation limit-20%) is also depicted in chart.Known (the fusing limit+20%), lower than the minimum electric current (▲) that breaks, on the other hand, (the misoperation limit-20%) is higher than maximum normal current (◆).
