At first, connect successively decrease switch 500b and connect power supply of secondary coil, open bulb 200, the S61 lamp is bright.
Then, open the bulb switching device and make the power supply supply discontinuity, cause that thus bulb 200 is switched off (light-off) S62.
Through confirming after this process that bulb restarts switching device and whether starts S64.
Through confirming that ignition device starts again,, can judge the whether fully cooling of bulb 200 and variable high-voltage generator 500 and magnetron 100, S65 according to cooling device 700.
If fully cooled off, bulb 200 can reopen, and not so opens secondary coil and successively decreases behind the switch 500b, connects power supply to transformer, reopens bulb 200, S66 according to being incorporated into secondary voltage.
After after a while, connect the secondary coil switch 500b that successively decreases, continue to connect power supply, start bulb 200, S68.
Have the primary and secondary coil switch 500a that successively decreases simultaneously, the example of 500b has demonstration in Fig. 8 and Fig. 9.Promptly open the primary coil switch 500a that successively decreases, connect the secondary coil switch 500b that successively decreases, connect power supply, open bulb 200, S81.
Turn off bulb 200, interrupt the power supply supply, turn off bulb 200, S82, S83.
Open bulb 200 again, confirm cooling time,, just connect the primary coil switch 500a that successively decreases, open the secondary coil switch 500b that successively decreases, reopen bulb 200, S84～S86 if confirm to cool off.
After operation above-mentioned action of a period of time, open the primary coil switch 500a that successively decreases, connect the secondary coil switch 500b that successively decreases, continue to connect power supply then, open bulb 200, S87, S88.
Therefore, the present invention increases the secondary voltage of transformer from the transformer increase and decrease primary coil and the secondary coil number of turns of variable high-voltage generator 500, the voltage that is applied to magnetron 100 is risen, increase the microwave amount, the certain hour required according to cooling makes bulb 200 luminous.
