Description

High pressure discharge lamp lighting apparatus and ligthing paraphernalia
Technical field
The present invention relates to a kind of high pressure discharge lamp lighting apparatus that all can light for the high-pressure discharge lamp that contains mercury and not mercuric high-pressure discharge lamp and the ligthing paraphernalia that has used this high pressure discharge lamp lighting apparatus.
Background technology
A kind of high pressure discharge lamp lighting apparatus had before been arranged, can light the high-pressure discharge lamp that contains mercury of a plurality of rated power (rated power), and differentiate the rated power of this high-pressure discharge lamp automatically, and make high-pressure discharge lamp lighting with the rated power that is determined.This high pressure discharge lamp lighting apparatus, it is difference according to the rising characteristic of the modulating voltage of the evaporation of caused mercury after following the lamp startup, differentiate the rated power of high-pressure discharge lamp, thus, when lamp starts and all can differentiate the rated power (for example, opening 2005-310677 communique (the 9th～10 page, Fig. 9～12)) of high-pressure discharge lamp under arbitrary situation of lamp when restarting with reference to the Japan Patent spy.
In recent years, from considering the viewpoint of carrying capacity of environment, carrying out the not research of the commercialization of mercuric high-pressure discharge lamp.This not mercuric high-pressure discharge lamp, though rated power is identical with the high-pressure discharge lamp that contains mercury, but it is different with the high-pressure discharge lamp that contains mercury to light characteristic, therefore be difficult to dual-purpose and contain the high pressure discharge lamp lighting apparatus that the high-pressure discharge lamp of mercury is used, the high pressure discharge lamp lighting apparatus that needs not mercuric high-pressure discharge lamp to use.
And, containing in the high-pressure discharge lamp of mercury and the not mercuric high-pressure discharge lamp under the general or similar situation at size and lamp socket, even if contain the high pressure discharge lamp lighting apparatus of the high-pressure discharge lamp special use of mercury, also might load onto not mercuric high-pressure discharge lamp, thereby might utilize script and inappropriate control to make high-pressure discharge lamp lighting.
Summary of the invention
The present invention researches and develops in view of these problems, and its purpose is to provide a kind of can differentiate the high-pressure discharge lamp that contains mercury and the not high pressure discharge lamp lighting apparatus of the kind of mercuric high-pressure discharge lamp and the ligthing paraphernalia that has used this high pressure discharge lamp lighting apparatus.
The present invention's aforesaid (being that claim 1 is described) high pressure discharge lamp lighting apparatus comprises: modulating voltage testing agency, detect modulating voltage; Lamp kind mechanism for identifying, according to when lamp starts by the detected modulating voltage of modulating voltage testing agency, differentiate the high-pressure discharge lamp or the not mercuric high-pressure discharge lamp that contain mercury; And the lamp powered controls, control lamp power corresponding to the lamp kind that lamp kind mechanism for identifying is determined.
In the present invention and following invention, as long as limit especially, then the definition of term and art-recognized meanings are as follows.
High-pressure discharge lamp for example comprises metal halide lamp (metal halide lamp) or high-pressure sodium lamp (High Pressure Sodium Lamp) etc., is enclosing the discharge medium that contains metal halide or rare gas in the high-pressure discharge lamp.In high-pressure discharge lamp, the high-pressure discharge lamp and not mercuric high-pressure discharge lamp that contain mercury are arranged.What is called does not contain mercury, is meant not contain mercury fully or do not contain mercury in fact.
As the high-pressure discharge lamp that contains mercury, when lamp starts, at first rare gas can discharge and produce fixing modulating voltage, and then along with the rising of temperature, the mercury accelerated evaporation, when mercury after evaporation and modulating voltage sharply increase fully sharp, because mercury evaporates fully, thereby the rising of the modulating voltage mitigation that becomes sharp.That is the flex point (inflection point) of rapid minimizing has taken place in the rising of modulating voltage when mercury evaporates fully.After this flex point, modulating voltage rises gently, and then along with the rising of temperature, the evaporation of metal halide increases, though when degree was evaporated fully not as good as mercury, modulating voltage still increased relatively more sharp, modulating voltage becomes stable afterwards.And, containing the high-pressure discharge lamp of mercury and compare with not mercuric high-pressure discharge lamp, the rising of the modulating voltage when having the lamp startup is fast, the characteristic that the modulating voltage when stablizing is high.
For not mercuric high-pressure discharge lamp, it mainly is the influence that evaporation brought that is subjected to rare gas and metal halide, therefore when lamp starts, modulating voltage rises gently, and can be as the described high-pressure discharge lamp that contains mercury, the flex point that the rising of the time point generation modulating voltage that evaporates fully at mercury sharply reduces.And not mercuric high-pressure discharge lamp is compared with the high-pressure discharge lamp that contains mercury, and the rising with modulating voltage is slow and mild, the characteristic that the modulating voltage when stablizing is low.
When so-called lamp starts, be meant from glow discharge (glow discharge) and transfer to the later situation of arc discharge (arc discharge), maximum comprise from begin after lamp starts to modulating voltage rise and stable till during, but also can from begin after lamp starts to modulating voltage rise and stable till during a part.
Modulating voltage testing agency can detect modulating voltage directly or indirectly and get final product, and is not limited to specific circuit and constitutes.And, the control the when detected value of modulating voltage testing agency also can be used for stable the lighting of high-pressure discharge lamp.
Lamp kind mechanism for identifying utilizes the different of the rising characteristic contain the high-pressure discharge lamp of mercury and the modulating voltage of not mercuric high-pressure discharge lamp when lamp starts, differentiates the lamp kind.
The lamp powered controls can switch to control with the lighting the corresponding lamp power of characteristic of high-pressure discharge lamp that determined and get final product, are not limited to specific circuit formation.
High pressure discharge lamp lighting apparatus of the present invention can the two be lighted to the high-pressure discharge lamp that contains mercury and not mercuric high-pressure discharge lamp.At this moment, the nearer relatively high-pressure discharge lamp of wattage that for example to be 20W wait to about the 70W.
And form is preferably, as the lower high-pressure discharge lamp of the wattage of object.Reason is, if the high-pressure discharge lamp of high wattage, then the time till determining the lamp kind is longer relatively, so also might be because of high-pressure discharge lamp being imported high power to differentiate generation deteriorations such as causing electrode, but if the high-pressure discharge lamp of low wattage, the time that then is used for differentiating the lamp kind is shorter relatively, thereby can suppress the load to high-pressure discharge lamp.
And, because (for example, arc light shifted the back 0～5 second) is easy to generate modulating voltage moment and uprises the wild effect that waits after starting, thus the moment (timing) of the kind of lamp kind mechanism for identifying differentiation lamp be preferably the change that does not comprise after the startup.This is because following phenomenon: attached to micro-medicine or the mercury on the electrode of high-pressure discharge lamp, discharge impact in the time of can shifting because of insulation breakdown or arc light and thermal shock moment disperse or evaporate, thereby float in luminous tube, thus, these drifts have the phenomenon that produces voltage (electric potential gradient (potential gradient)).If there is not this phenomenon, only present roughly the modulating voltage that discharge produced after then starting by the rare gas of being enclosed, subsequently, till the time that mercury or medicine fully evaporate (for example 15～60 seconds), modulating voltage can take place roughly not rise during.Relative therewith, if produce described phenomenon, then for example after startup 0～1 second, have that voltage when starting stable after 10 seconds is compared and the burr shape voltage crest (voltage peak) (is that time, the longitudinal axis are in the chart of modulating voltage at transverse axis) that reaches 1.5 to 3 times of voltages.This crest also presents a plurality of or mild overlapping situation of peak shape mostly.In most cases, after 2～15 seconds, phenomenon and the material of the evaporation of dispersing thus, even on the tube wall that temperature is very low comparatively speaking fluidized solidization once more, therefore described spread of voltage rises and finishes.Therefore,, differentiate the lamp kind, can differentiate with higher precision thus by no longer producing the later modulating voltage of instability rising of voltage.
And, high pressure discharge lamp lighting apparatus, modulating voltage when starting according to lamp is differentiated the high-pressure discharge lamp and not mercuric high-pressure discharge lamp that contains mercury, and control lamp power corresponding to the lamp kind that is determined, under arbitrary situation of the high-pressure discharge lamp that contains mercury and mercuric high-pressure discharge lamp not, all can prevent the generation of problem thus.

Secondly, the action to the 1st execution mode describes.
At first, in Fig. 1, the circuit operation of high pressure discharge lamp lighting apparatus 15 is described.
By energized, utilize diode bridge 21 to come the voltage of commercial ac power source e is carried out full-wave rectification.Control circuit 24, detect input side and the voltage of outlet side and the voltage or the electric current that detects above-mentioned detecting element Z1 of boost chopper 22, field-effect transistor Q1 is carried out conducting, disconnects control, with the power factor (PF) of improvement, and boost from the direct voltage of diode bridge 21.
And control circuit 24 makes ignitor circuit 26 actions, utilizes described ignitor circuit 26 that the secondary coil Tr2 of transformer Tr is gone up and produces high-voltage pulse.
And, the field-effect transistor Q2 and the field-effect transistor Q3 of control circuit 24 controls one adjuster circuit 25.
That is, when field-effect transistor Q2 conducting, in the closed circuit of secondary coil Tr2, high-pressure discharge lamp 13, detecting element Z2 and the capacitor C2 of capacitor C2, field-effect transistor Q2, inductor L3, transformer Tr, there is electric current to flow.
When field-effect transistor Q2 disconnects, be accumulated in the electric current among the inductor L3, in the closed circuit of secondary coil Tr2, high-pressure discharge lamp 13, detecting element Z2, capacitor C3, diode D6 and the inductor L3 of transformer Tr, flow.

And, in the control circuit 24,, and the conducting of controlling filed effect transistor Q2 and field-effect transistor Q3, disconnect action from the detected value of each detecting element Z2, Z3 input lamp current and modulating voltage.
Like this, by the conducting of field-effect transistor Q2 and field-effect transistor Q3, the action of disconnection, and high-pressure discharge lamp 13 is applied square-wave voltage, and on described square-wave voltage overlapping high-voltage pulse from ignitor circuit 26, high-pressure discharge lamp 13 is started light.
In addition, after high-pressure discharge lamp 13 starts, corresponding to by the detected lamp current of detecting element Z2, the output of ignitor circuit 26 stop pulses.
Then, the high-pressure discharge lamp 13 that utilizes high pressure discharge lamp lighting apparatus 15 to differentiate to contain mercury and not mercuric high-pressure discharge lamp 13 and the situation of carrying out the bright control of optimum are described.
Among Fig. 2, expression utilizes high pressure discharge lamp lighting apparatus 15, the voltage-current characteristic when starting light with the high-pressure discharge lamp 13 corresponding lamp power that contain mercury.
Among Fig. 3, expression utilizes high pressure discharge lamp lighting apparatus 15, with voltage-current characteristic shown in Figure 2, and the time of the lighting-modulating voltage characteristic the when high-pressure discharge lamp 13 that contains mercury and not mercuric high-pressure discharge lamp 13 are started light respectively, that is the rising characteristic of modulating voltage.
The high-pressure discharge lamp 13 that contains mercury is when lamp starts, at first, noble gas discharge and produce fixing modulating voltage, and then along with the rising of temperature, the mercury accelerated evaporation, evaporate fully sharp by mercury modulating voltage is increased sharp with the climbing of maximum after the rising of modulating voltage becomes mild sharp because mercury evaporates fully, that is, the flex point P of rapid minimizing has taken place in the rising of the time point modulating voltage that evaporates fully at mercury.After this flex point P, modulating voltage gently rises, and then along with the rising of temperature, the evaporation of metal halide increases, though when degree was evaporated fully not as good as mercury, modulating voltage still increased relatively more sharp, modulating voltage becomes stable afterwards.And the high-pressure discharge lamp 13 that contains mercury is compared with not mercuric high-pressure discharge lamp 13, and the rising with lamp modulating voltage when starting is very fast, and the higher characteristic of modulating voltage when stable.
Not mercuric high-pressure discharge lamp 13, the influence of no mercury steam, and mainly be the influence that evaporation brought that is subjected to rare gas and metal halide, therefore, when lamp starts, modulating voltage gently rises, and can be as the described high-pressure discharge lamp 13 that contains mercury, and the flex point P that sharply reduces can not take place in the rising of the time point modulating voltage that evaporates fully at mercury.And not mercuric high-pressure discharge lamp 13 is compared with the high-pressure discharge lamp 13 that contains mercury, and the rising with modulating voltage is slow and mild, and the lower characteristic of modulating voltage when stable.
And the lamp kind mechanism for identifying of control circuit 24 utilizes the different of the rising characteristic contain the high-pressure discharge lamp of mercury and the modulating voltage of not mercuric high-pressure discharge lamp when lamp starts, differentiates the lamp kind.As lamp kind method of discrimination, the 1st to the 4th lamp kind method of discrimination shown below is for example arranged.
In the 1st lamp kind method of discrimination, according to the detection of modulating voltage, the modulating voltage when detecting the lamp startup has or not flex point P, differentiates the high-pressure discharge lamp 13 or the not mercuric high-pressure discharge lamp 13 that contain mercury thus.Particularly, when lamp starts, begin in stipulated time about 100 seconds for example from energized, the variation of the variable quantity (gradient) when the monitoring modulating voltage rises, when described variation presents when reducing, and the maximum of the variable quantity that is reduced is differentiated the high-pressure discharge lamp 13 that contains mercury for being during greater than predetermined reference value, and, differentiate for being not mercuric high-pressure discharge lamp 13 when the maximum of the described variable quantity that reduces during less than predetermined reference value.
Represent among Fig. 4, under the situation of the high-pressure discharge lamp 13 that contains mercury, the variation of the variable quantity the when modulating voltage that rises when lamp starts rises.When mercury evaporated fully, when promptly the variation of the rising of modulating voltage reduced sharp after flex point P, the maximum that becomes the variable quantity of negative value became big when lamp starts.On the other hand, represent among Fig. 5, under the situation of not mercuric high-pressure discharge lamp 13, the variation of the variable quantity the when modulating voltage that rises when lamp starts rises.When starting, lamp can not produce the flex point P that causes because of the complete influence of evaporation of mercury, so it is less to become the maximum of variable quantity of negative value.Thus, fiducial value be the maximum that is set at the variable quantity that becomes negative value of the described high-pressure discharge lamp 13 that contains mercury, with the value of the peaked centre of the variable quantity that becomes negative value of not mercuric high-pressure discharge lamp 13.
Under the situation of the high-pressure discharge lamp 13 that contains mercury, when lamp starts, the time point that evaporates fully at mercury produces the flex point P of the rapid minimizing of rising of modulating voltage, can differentiate and be, the variation of the variable quantity when modulating voltage rises after this flex point P reduces, and therefore the maximum of the described variable quantity that becomes negative value can differentiate the high-pressure discharge lamp 13 that contains mercury for being greater than predetermined reference value.
Under the situation of not mercuric high-pressure discharge lamp 13, when lamp starts, can be as the high-pressure discharge lamp 13 that contains mercury, the flex point P that sharply reduces can not take place in the rising of modulating voltage, but modulating voltage gently rises, thereby can differentiate is, when modulating voltage begins to stablize etc., the variation of the variable quantity when modulating voltage rises reduces, and therefore the maximum of the described variable quantity that becomes negative value can be differentiated for being not mercuric high-pressure discharge lamp less than predetermined reference value.
And, in the 2nd lamp kind method of discrimination,, detect high-pressure discharge lamp 13 beginning stable status according to the detection of modulating voltage, and detect modulating voltage under this state, differentiate high-pressure discharge lamp 13 or not mercuric high-pressure discharge lamp 13 thus for containing mercury.Particularly, variable quantity when the modulating voltage that monitoring is risen when lamp starts rises, variable quantity when modulating voltage rises becomes less than predetermined variation value when modulating voltage begins to stablize, and when modulating voltage is higher than predetermined reference value, differentiate is to be the high-pressure discharge lamp that contains mercury, and when modulating voltage is lower than predetermined reference value, then differentiate for being not mercuric high-pressure discharge lamp.
For example, detect modulating voltage with 1 second interval, current modulating voltage and the modulating voltage before 5 seconds are compared, if poor (displacement) of voltage is in the 0.5V at predetermined displacement value place, then differentiation has begun to stablize for modulating voltage.When the modulating voltage of this moment is higher than predetermined reference value, differentiates the high-pressure discharge lamp that contains mercury for being, and when modulating voltage is lower than predetermined reference value, then differentiate for being not mercuric high-pressure discharge lamp.
Perhaps, detect modulating voltage with 1 second interval, storage calculates mean value and standard deviation from current lamp voltage value till before 10 seconds.When with standard deviation divided by the value (displacement) of mean value gained smaller or equal to 0.005 (promptly 0.5%) at predetermined displacement value place when following, differentiate for modulating voltage and begin to stablize.When the modulating voltage of this moment is higher than predetermined reference value, differentiates the high-pressure discharge lamp that contains mercury for being, and when modulating voltage is lower than predetermined reference value, then differentiate for being not mercuric high-pressure discharge lamp.
In these cases, the variable quantity in the time of the modulating voltage after the flex point P must being risen is during less than predetermined variation value, and the variable quantity the when modulating voltage when beginning stablize with modulating voltage rises is distinguished during less than the variation value be scheduled to.At this moment, for example continue about 30 seconds stipulated time, the variable quantity when modulating voltage rises is during less than the variation value be scheduled to, just can differentiate for modulating voltage to begin to stablize.When the variable quantity the when modulating voltage after the flex point P rises becomes less than predetermined variation value,, so can differentiate for being not that modulating voltage is when beginning to stablize because the variable quantity when modulating voltage rises at the appointed time becomes greatly once more.
With regard to fiducial value, when the modulating voltage that rises begins to stablize, the modulating voltage of high-pressure discharge lamp 13 that contains mercury is higher, and the modulating voltage of not mercuric high-pressure discharge lamp 13 is lower, therefore fiducial value is set at the modulating voltage of the described high-pressure discharge lamp 13 that contains mercury and the value of the centre of the modulating voltage of not mercuric high-pressure discharge lamp 13, for example is set at 60V.
And, under the situation of the high-pressure discharge lamp 13 that contains mercury, variable quantity when the modulating voltage that rises when lamp starts rises becomes less than predetermined variation value when modulating voltage begins to stablize, described modulating voltage is higher than predetermined reference value, therefore can differentiate the high-pressure discharge lamp 13 that contains mercury for being.
Under the situation of not mercuric high-pressure discharge lamp 13, variable quantity when the modulating voltage that rises when lamp starts rises becomes less than predetermined variation value when modulating voltage begins to stablize, described modulating voltage is lower than predetermined reference value, therefore can differentiate for being not mercuric high-pressure discharge lamp.
And, in the 3rd lamp kind method of discrimination, the variable quantity of unit interval when the modulating voltage that will rise when lamp starts rises to compare with predetermined reference value, when variable quantity surpasses fiducial value, differentiate is to be the high-pressure discharge lamp 13 that contains mercury, and when variable quantity does not surpass fiducial value, then differentiate for being not mercuric high-pressure discharge lamp 13.
The variable quantity of unit interval for example is the variable quantity that was made as for 3 seconds.
Represent among Fig. 6, under the situation of the high-pressure discharge lamp 13 that contains mercury, the variable quantity of the unit interval the when modulating voltage that rises when lamp starts rises.When lamp started, when mercury evaporated sharp fully, modulating voltage increased sharp towards flex point P, and the variation quantitative change of the unit interval of this moment is big.On the other hand, represent among Fig. 7, under the situation of not mercuric high-pressure discharge lamp 13, the variable quantity of the unit interval the when modulating voltage that rises when lamp starts rises.When lamp starts, can not produce the flex point P that is brought by the complete influence of evaporation of mercury, but modulating voltage increases gently, the variable quantity of unit interval is less.Thus, with regard to fiducial value, the value of the centre of the variable quantity of the unit interval that to be the modulating voltage that is made as the high-pressure discharge lamp 13 that contains mercury gently increase towards the variable quantity of the unit interval that flex point P sharply increases, with the modulating voltage of not mercuric high-pressure discharge lamp 13, for example, the variable quantity in 3 seconds of modulating voltage is set at 4.05V (1.35V/sec).
Under the situation of the high-pressure discharge lamp 13 that contains mercury, when lamp starts, rising along with temperature, the mercury accelerated evaporation, mercury sharp fully the evaporation and modulating voltage increases sharp towards flex point P, thus, the variable quantity of the unit interval when described modulating voltage rises surpasses predetermined reference value, therefore can differentiate the high-pressure discharge lamp 13 that contains mercury for being.
Under the situation of not mercuric high-pressure discharge lamp 13, when lamp starts, situation as the high-pressure discharge lamp that contains mercury " mercury sharp fully the evaporation and modulating voltage sharply increase towards flex point P " can not take place, but modulating voltage can gently rise, thus, the variable quantity of unit interval when described modulating voltage rises does not surpass predetermined reference value, therefore can differentiate for being not mercuric high-pressure discharge lamp 13.
Herein, the result of test is implemented in expression at the rising of the modulating voltage of high-pressure discharge lamp 13.
At first, power is the special high-pressure lighting apparatus for discharge lamp of 15W when utilizing rated power for 35W, startup, (the CDM 35W that makes of Philips company for example that makes that bulb thermal capacity is big, temperature rises to minimum condition, it is cylinder type heavy wall type aluminium oxide bulb, to enclose about 0.2 atmospheric pressure metal halide medicine, mercury, Ar gas are arranged in the bulb) the high-pressure discharge lamp that contains mercury when vertically lighting, the maximum variable quantity of modulating voltage in 3 seconds is 5.22V (1.74V/sec).The value of described 5.22V (1.74V/sec) surpasses predetermined reference value 4.05V (1.35V/sec), therefore can differentiate the high-pressure discharge lamp 13 that contains mercury for being.
On the other hand, power is the high pressure discharge lamp lighting apparatus 15 of 35W when utilizing rated power for 35W, startup, bulb thermal capacity minimum, temperature are risen, and (bulb is the bulb of the oxidation aluminum of long 34mm and wall thickness 0.5mm to bigger condition, be to have ID 6mm ball and have the integrally formed bulb of ID0.7mm tubule at two ends in central authorities, and then, enclose the TmI that 4mg is arranged with 13 atmospheric pressure in the bulb 3The ZnI of-NaI (60: 40 percentage by weights (wt%)), 0.2mg 2, and Xe gas) the maximum variable quantity of not mercuric high-pressure discharge lamp 13 when vertically lighting be 1.5V (0.5V/sec).And, power is the high pressure discharge lamp lighting apparatus 15 of 35W when utilizing rated power for 35W, startup, bulb thermal capacity minimum, temperature are risen, and (bulb is the bulb of the oxidation aluminum of long 34mm and wall thickness 0.5mm to also maximum condition, be to have ID 6mm ball and have the integrally formed bulb of ID 0.7mm tubule at two ends in central authorities, and then, enclose the TmI that 4mg is arranged with 0.2 atmospheric pressure in the bulb 3-NaI (60: 40wt%), the ZnI of 0.2mg 2, and Ar gas) the maximum variable quantity of not mercuric high-pressure discharge lamp 13 when vertically lighting be 2.85V (0.95V/sec).The value of described 1.5V (0.5V/sec) or 2.85V (0.95V/sec), fully, therefore can differentiate for being not mercuric high-pressure discharge lamp 13 less than the variable quantity 5.22V (1.74V/sec) and the fiducial value 4.05V (1.35V/sec) of the high-pressure discharge lamp 13 that contains mercury.
In the not mercuric high-pressure discharge lamp 13, the medicine that forms modulating voltage is that voltage forms with medicine (ZnI 2Deng) and main light emission medicine (TmI 3, HoI 3Deng) the two, in the two, ZnI 2Relatively low less than 500 ℃ temperature under fusion and vapour pressure improves, thereby evaporation fully sometimes in lighting process.Therefore, enclosing more ZnI 2Kind in, though voltage rise to increase, far above the rapid temperature of evaporation of mercury, so, also do not reach the variable quantity under the minimum of the high-pressure discharge lamp 13 that contains mercury even if under the situation of the variable quantity maximum of not mercuric high-pressure discharge lamp 13.
Therefore can learn, be that differentiate and has or not mercury on the boundary with fiducial value 4.05V (1.35V/sec), also can differentiate exactly.
In addition, fiducial value is according to the wattage (Watt) of the high-pressure discharge lamp 13 that is suitable for and difference, be preferably set to the modulating voltage that contains the high-pressure discharge lamp 13 of mercury in each the lamp wattage (W) that is suitable for, with the median of the modulating voltage of not mercuric high-pressure discharge lamp 13.And the lamp wattage is big more, and then fiducial value has more little tendency.
It is unstable that high-pressure discharge lamp 13 rarely becomes sometimes, thereby produce paroxysmal change in voltage in the several seconds in the interior short time randomly, must eliminate this paroxysmal change in voltage.At this moment, when in 3 seconds, detecting paroxysmal change in voltage, differentiation 3 seconds before this with originally 3 seconds in totally 6 seconds modulating voltage whether change continuously, if change continuously, then differentiate is to be the high-pressure discharge lamp 13 that contains mercury, and if change discontinuously, then can be considered as is paroxysmal change in voltage and with its elimination.
And, in the 4th lamp kind method of discrimination, the rising of the modulating voltage when the lamp of the high-pressure discharge lamp 13 that contains mercury starts becomes mild and the moment (timing) before and after beginning to stablize, that is, the moment after from energized to stipulated time about 100 seconds for example is if modulating voltage is higher than predetermined reference value, then differentiate for containing the high-pressure discharge lamp 13 of mercury, on the contrary, if modulating voltage is lower than predetermined reference value, then differentiation is not mercuric high-pressure discharge lamp 13.Fiducial value as the benchmark of this differentiation, in the moment that the rising of the modulating voltage the when lamp that is preferably set at the high-pressure discharge lamp 13 that contains mercury starts finishes, contain the median between the modulating voltage of the modulating voltage of high-pressure discharge lamp 13 of mercury and not mercuric high-pressure discharge lamp 13.
And, utilize any or several combination in the 1st to the 4th lamp kind method of discrimination of lamp kind mechanism for identifying of control circuit 24, can differentiate the lamp kind exactly, therefore the lamp powered controls of control circuit 24 are controlled with the corresponding lamp power of characteristic of lighting of the high-pressure discharge lamp 13 that switches to and determined.
Like this, high pressure discharge lamp lighting apparatus 15, it still is not mercuric high-pressure discharge lamp 13 that modulating voltage when starting according to lamp is differentiated the high-pressure discharge lamp 13 that contains mercury, and control lamp power corresponding to the lamp kind that is determined, therefore all can light for any of high-pressure discharge lamp 13 that contains mercury and not mercuric high-pressure discharge lamp 13 by Optimal Control, thus can dual-purpose high pressure discharge lamp lighting apparatus 15.
And expression contains the voltage-power characteristic of the high-pressure discharge lamp 13 and the not mercuric high-pressure discharge lamp 13 of mercury among Fig. 8.The load lamp voltage of described high-pressure discharge lamp 13 has nothing in common with each other, but has constant output characteristic near load lamp voltage separately.And the high-pressure discharge lamp 13 that contains mercury is compared with not mercuric high-pressure discharge lamp 13, and the modulating voltage uphill process that begins after lamp starts, power is relatively low.
Therefore, the modulating voltage uphill process that after lamp starts, begins, utilize with as shown in Figure 8 as the corresponding lamp power of characteristic of the relatively low high-pressure discharge lamp that contains mercury 13 of power control, thus, the rising of modulating voltage that contains the high-pressure discharge lamp 13 of mercury becomes obvious, and the difference of the modulating voltage of easy and not mercuric high-pressure discharge lamp 13 is come, thereby can improve the discrimination precision of lamp kind.
And control circuit 24 possesses: storing mechanism, the lamp kind that is determined by lamp kind mechanism for identifying during storage the lighting for the first time of high-pressure discharge lamp 13; And replacement mechanism, institute's canned data in the described storing mechanism is reset, and then, the lamp powered controls of control circuit 24, to control with the corresponding lamp power of lamp kind that is determined by lamp kind mechanism for identifying when the lighting for the first time of high-pressure discharge lamp 13, and when next later the lighting of high-pressure discharge lamp 13, then with storing mechanism in the corresponding lamp power of lamp kind stored control.Replacement mechanism for example can utilize the operation of replacement button to reset, and also can perhaps the detecting of electric connection state etc. automatically be reset by the detecting of transducer to the loading and unloading of high-pressure discharge lamp.
And, control circuit 24 can be controlled by following mode, if the lamp kind that is: is determined is in beyond the suitable lamp kind of described high pressure discharge lamp lighting apparatus 15, does not then supply with lamp power, thereby can prevent to load onto suitable lamp kind lamp in addition by mistake.
By storing and utilize the lamp kind that is determined by this way, can when lamp starts, begin just to utilize with the corresponding suitable lamp power of lamp kind and control high-pressure discharge lamp 13.Therefore, the rising that can prevent light beam when lamp the starts problem that electrode extremely slow or high-pressure discharge lamp 13 bears burdens and so on that becomes.
Secondly, Figure 10 to Figure 13 represents the 2nd execution mode, Figure 10 is the circuit diagram of high pressure discharge lamp lighting apparatus, Figure 11 utilizes high pressure discharge lamp lighting apparatus, the chart of the voltage-current characteristic when starting light with the corresponding lamp power of not mercuric high-pressure discharge lamp, Figure 12 utilizes the high pressure discharge lamp lighting apparatus with voltage-current characteristic shown in Figure 11, the chart of the time of the lighting-modulating voltage characteristic the when high-pressure discharge lamp that contains mercury and not mercuric high-pressure discharge lamp are started light respectively, Figure 13 are the tables of the normal range (NR) of the modulating voltage of expression high pressure discharge lamp lighting apparatus in high-pressure discharge lamp that contains mercury and not mercuric high-pressure discharge lamp.
