In step S102, in the transient process after this HID lamp starts, measure the actual electric parameter value of this HID lamp, and produce the startup transient state electric characteristic value of this HID lamp in view of the above in this predetermined point of time.At present embodiment, this startup transient state electric characteristic value is measured actual electric parameter value.More particularly, the electric parameter value of this reality is the actual current parameter value, is designated as i (15).Then carry out step S103.
In step S103, judge whether this startup transient state electric characteristic value of measuring and obtaining falls into stored startup transient state electric characteristic value scope (promptly first starts the transient state electric characteristic value scope or the second startup transient state electric characteristic value scope), if then carry out step S104, (that is measure and the startup transient state electric characteristic value that obtains does not fall into stored arbitrary startup transient state electric characteristic value scope) if not then proceeds to step S109.
In step S104, judge whether this startup transient state electric characteristic value that measures falls into first and start transient state electric characteristic value scope, if first starts transient state electric characteristic value scope, then proceed to step S105, if not, represent that then this startup transient state electric characteristic value that measures is to fall into the second stored startup transient state electric characteristic value scope, then proceeds to step S107.
In step S105, according to data stored in step S100, hunt out from stored data should first starting first rated power of transient state electric characteristic value scope, at this moment, the rated power that promptly accurately picks out this HID lamp is first rated power.Then carry out step S106.
In step S106, according to the stored rated power and the corresponding incidence relation of ballast driven parameter value, from stored data, hunt out ballast driven parameter value that should first rated power, and export it to this ballast, so that the normally operation under first rated power of correspondence of this HID lamp, and finish this drive controlling process.
In step S107,, from stored data, hunt out should second starting second rated power of transient state electric characteristic value scope according to stored data in step S100.Then carry out step S108.
In step S 108, according to the stored rated power and the corresponding incidence relation of ballast driven parameter value, from stored data, hunt out ballast driven parameter value that should second rated power, and exported to this ballast, so that the normally operation under second rated power of correspondence of this HID lamp, and finish this drive controlling process.
In step S109, for example information such as sound or indicator light is provided, be not to be each stored in advance rated power with the rated power of pointing out current this HID lamp, thereby for the stored data of follow-up continual renovation.
See also Fig. 2, show the flow chart of another embodiment of operating procedure of the drive control method for ballast of high-intensity gas discharge lamp of the present invention.In the present embodiment, being respectively first, second, reaching the 3rd rated power with the rated power that prestores is that example describes.It should be noted that herein, the rated power kind that prestores is not limited to the foregoing description and present embodiment, certainly, prestore the rated power kind the more, then the attainable discriminating function of the present invention is more powerful, in addition, how many rated power kinds that no matter prestores has, and all do not break away from the described operational mode of the foregoing description and present embodiment.
Shown in Fig. 2 (A) and Fig. 2 (B), at first, execution in step S200 stores first, second, reaches the HID lamp startup transient state electric characteristic value scope of the 3rd rated power, a plurality of each rated power of correspondence and the ballast driven parameter value of a plurality of each rated power of correspondence.Wherein, in the present embodiment, first of each HID lamp starts transient state electric characteristic value and is respectively first predetermined point of time of the transient process after this HID lamp starts and the difference of the actual electric parameter value between second predetermined point of time; Second starts transient state electric characteristic value then is respectively first predetermined point of time of the transient process after this HID lamp starts and the difference of the actual electric parameter value between the 3rd predetermined point of time, and should the electric parameter value of reality be light tube electric voltage, electric current and/or performance number.At present embodiment, with this first, this second, and the 3rd rated power be respectively 20 watts (W), 35 watts (W), and 70 watts (W), and with the electric parameter value of reality is that the lamp current value is that example describes, and this first predetermined point of time and this second and third predetermined point of time are respectively and start back the 5th second, the 15th second, and the 35th second, and this first starts transient state electric characteristic value scope and exceed 1.5 amperes (A) for first of this HID lamp starts transient state electric characteristic value (the current parameters difference after promptly starting back the 5th second and starting between the 15th second); The second startup transient state electric characteristic value (the current parameters difference after startup back the 5th second and the startup between the 35th second) that this second startup transient state electric characteristic value scope is this HID lamp exceeds 1.5 amperes (A); The 3rd startup transient state electric characteristic value scope is that second of this HID lamp starts transient state electric characteristic value less than 1.5 amperes (A).Then the startup transient state electric characteristic value scope of the HID lamp correspondence of 20 watts of rated power is this first startup transient state electric characteristic value scope; The startup transient state electric characteristic value scope of the HID lamp correspondence of 35 watts of rated power is this second startup transient state electric characteristic value scope; It is the 3rd startup transient state electric characteristic value scope that the HID lamp of 70 watts of rated power starts transient state electric characteristic value scope.Then carry out step S201.
