管支持構体を示す。Next, a resistor 4 connected in parallel with SSS 3 stabilizes the phase of the breakover voltage of the starter, and
A resistor having a resistance value of 20 to LookΩ is used depending on the magnitude of polarization of EC2. A feature of the present invention is that, for example, when an attempt is made to start a discharge lamp in a low temperature atmosphere, the coercive voltage of FEC2 increases and SSS3 becomes ONL with respect to the input voltage.
When not in use, a series circuit of the FEC 2 and the resistor 4 is formed, current flows through the circuit, and the resistor 4 generates heat. In Figure 7, 1/4W-P type is used for resistor 4, Ω is used for 30, and FEC
2 is a temperature rise curve of the resistor 4 in vacuum when a resistor 4 having a diameter of 16.5 mm and a thickness of 0.6511I11 is used. According to this, the temperature rise after 100 seconds has passed is about 150 degrees, and the FEC 2 is heated by heat radiation and/or heat conduction from the heating resistor. This lowers the coercive voltage of FEC2, so SSS3 is easily turned on. Therefore, the breakover voltage of SSS 3 can be set relatively high in advance. FIG. 8 shows a modification of the circuit shown in FIG. 1, in which a starting auxiliary conductor 13 is provided along the arc tube 5, and an FEC
A discharge resistor 14 is connected in parallel with 2 to discharge a pyroelectric current when the FEC is depolarized. FIG. 9 also shows a modified example of the circuit, in which the starting auxiliary conductor 13 is separated from the circuit by two thermally responsive switches 1 and 1', and a discharge resistor 14 is connected in parallel with the series circuit of FEC 2 and SSS 3. It is connected. FIG. 10 shows an arc tube support structure in which the circuit configuration shown in FIG. 9 is applied to a 360 W high-pressure sodium lamp lit by a 400 W mercury lamp ballast.

When cooled to ℃ and applied an AC power supply voltage of 188 ■,
The lamp started after about 40 seconds. This indicates that the temperature of the FEC, which was cooled to 40° C., rose due to heat radiation and conduction from the resistor 4, and its coercive voltage decreased.

できる。Further, when the lamp is restarted, the ambient temperature around the FEC is extremely high, and the nonlinear characteristics of the FEC are degraded, so a higher pulse voltage can be generated by combining it with SSS, which has a high breakover voltage. This leads to shortening the return time of the thermally responsive switch.
As a result, the lamp restart time can be shortened. Furthermore, according to the present invention, the lamp can be started satisfactorily even in a low temperature atmosphere of -40° C. or lower. Furthermore, the present invention can be applied not only to high-pressure sodium lamps but also to other metal vapor discharge lamps such as metallurgical lamps.
