2. Description of the Related Art Conventionally, as a starter for a metal vapor discharge lamp such as a high-pressure sodium lamp, a starter having a high-pressure pulse generation circuit using a glow lamp is used to solve problems such as stability of operation and life. The one using a non-linear ceramic capacitor made of a ferroelectric material mainly composed of barium titanate having a non-linear VQ characteristic has come to be used. This utilizes the saturation characteristic of a non-linear capacitor to generate a pulse voltage every half cycle by the inductance of a ballast connected in series with this non-linear capacitor, and apply this to a high pressure vapor discharge lamp to start it. Next, a configuration example of a metal vapor discharge lamp including such a starter will be described with reference to FIG.

In FIG. 3, 1 is a high-pressure sodium lamp arc tube, 2 is a starting auxiliary electrode having thermal response switches 3a and 3b at both ends, 4 is a non-linear ceramic capacitor, 5 is a current damper, and 6 is an SSS element. A semiconductor switch 7 is a resistor connected in parallel to the semiconductor switch 6 for stabilizing the ON phase of the semiconductor switch, and includes a starting auxiliary electrode 2, thermal response switches 3a and 3b, a non-linear ceramic capacitor 4, and a current damper 5. A series circuit of the semiconductor switches 6 constitutes a starter, which is connected in parallel with the arc tube 1 and accommodated in the outer bulb to constitute a high pressure sodium lamp. However, only the semiconductor switch 6 is not arranged in the outer bulb, but is arranged in the base portion.

Next, the operation of the high-pressure sodium lamp thus constructed will be described. When the AC power supply 8 is turned on, a positive half cycle voltage is applied to the starter through the ballast 9, and when the breakover voltage of the semiconductor switch 6 is exceeded, the nonlinear ceramic capacitor 4 is rapidly charged. Immediately reach the saturation voltage and cut off the current rapidly. At this time, a large positive pulse voltage is generated due to the inductance of the ballast 9, and is applied to the arc tube 1 together with the power supply voltage. In the next negative half cycle, negative pulse voltages are likewise generated, which start and ignite the lamp. After lighting, the heat-responsive switches 3a and 3b are opened by receiving heat from the arc tube 1, and the starter is disconnected from the circuit.

By the way, in a metal vapor discharge lamp having a built-in starter including a non-linear ceramic capacitor as described above, particularly in a high-pressure sodium lamp having a high starting voltage, a lamp defect may occur. Sometimes the built-in starter keeps generating pulses. If the pulse continues to be generated at the time of the lamp failure, the following problem occurs. Since the coil portion and the core portion of the ballast are capacitively coupled, the pulse energy generated by the inductance of the ballast leaks into the metal housing of the lighting equipment in which the ballast is installed. Therefore, if the housing is not grounded, the human body feels a shock. The pulse voltage is continuously applied to the base of the lamp or the metal part of the lamp holder, which is dangerous to humans. Insulation of ballasts and insulation deterioration of wiring cables and sockets are caused. The pulse energy is radiated into the space as high-frequency noise, causing interference with television and radio waves.

In order to improve this point, the applicant of the present invention has previously disclosed in Japanese Patent Laid-Open No. 5-290985 that a heating resistor is connected in parallel to a non-linear ceramic capacitor and arranged in proximity to the non-linear ceramic capacitor so that when a lamp is not operating, We proposed a method in which the non-linear ceramic capacitor is heated to a Curie temperature or higher by heat radiation from the heating resistor to make the non-linear ceramic capacitor paraelectric so that the switching characteristic disappears and pulse generation is stopped. .

By the way, in the metal vapor discharge lamp configured as described above, if the resistance value of the heating resistor for the non-linear ceramic capacitor is small, the calorific value is large at the time of a fault, and therefore the pulse stop time is increased. Becomes shorter, but the generated pulse voltage becomes smaller. On the other hand, when the resistance value of the heating resistor is large, the generated pulse voltage is large, but the amount of heat generated at the point of failure is small, so that the pulse stop time is long. Therefore, it is necessary to stop the pulse without lowering the pulse voltage so much that the lower limit of the resistance value of the heating resistor is usually 30 kΩ and the upper limit thereof is 100 kΩ.

Further, in the metal vapor discharge lamp configured as described above, the pulse voltage required for lighting varies depending on the type of lamp, wattage, ballast, and other conditions, and the higher the wattage, the more the same. The pulse voltage is reduced even if the characteristic nonlinear ceramic capacitor is used. Therefore, prepare multiple types of non-linear ceramic capacitors with different diameters (diameter of the electrode film), and set the resistance values of the non-linear ceramic capacitors and their heating resistors according to the conditions such as lamp type and wattage. There was a problem that it had to be selected and used.

From Tables 1 and 2 above, when the value of A, that is, the ratio of the volume of the non-linear ceramic capacitor and the power consumption of the heating resistor is 305 mm 3 / W or less, the pulse generation at the time of astigmatism is completely eliminated. You can see that it can be stopped. Further, when the value of A is less than 110 mm 3 / W, the resistance value of the heating resistor becomes small and the generated pulse voltage decreases,
Normal starting becomes difficult. Therefore, the value of A is 110 to 305.
It is necessary to specify mm 3 / W, and in the present invention, the value of A is set in this way.

In the present invention, the distance L between the terminal lead of the nonlinear ceramic capacitor and the end of the heating resistor is L.
Is 1 to 5 mm, if L is less than 1 mm, it will be difficult to weld the lead of the heating resistor to the terminal lead of the nonlinear ceramic capacitor, and the nonlinear ceramic capacitor may be damaged. If it exceeds, it takes more than 5 minutes at room temperature (25 ° C) until the opposing position shifts and the pulse stops. The stop of the pulse is aimed at within 5 minutes at room temperature. Also,
The reason why the distance D between the welding point of the terminal lead of the nonlinear ceramic capacitor and the lead of the heating resistor is 1 to 5 mm is that if the D is less than 1 mm, the welding of the terminal lead of the nonlinear ceramic capacitor and the lead of the heating resistor will not occur. It is difficult and may damage the non-linear ceramic capacitor, and if D exceeds 5 mm, the terminal lead of the non-linear ceramic capacitor may be bent if the lamp falls during transportation, etc. It is set within the above range.
