にくくなっている。By the way, as shown in FIG. 4, in the lighting circuit, after the direct current, which is the output of the rectifying and smoothing circuit 21 that rectifies and smoothes the commercial power source, is interrupted by the switching circuit section 22, the lighting circuit is connected to the resonant circuit section 2.
3, the inverter-type lighting circuit is configured to obtain a high-frequency output by inputting an input signal to the lamps 1 and 2, and includes a preheating circuit section 24 that preheats the lamps 1 and 2, and a preheating control circuit section 25 that controls the preheating circuit section 24. It is equipped with The rectifying and smoothing circuit section 21 has a smoothing capacitor C at the output end, and the resonant circuit section 2
3 has a capacitor 26 and a choke coil 27. When the board 6 is divided into four sections by a straight line passing through the center of the board 6 and running in the longitudinal direction of the notch window 7 and a straight line passing through the center of the board 6 and running in the longitudinal direction of the notch 10, the rectifying and smoothing circuit section is divided into four sections. 21 and a switching circuit section 22 is provided on the opposite side of the output terminal 11 with the cutout window 7 in between. Further, the rectifying and smoothing circuit section 21 and the switching circuit section 22 are arranged in different sections. The smoothing capacitor C of the rectifying and smoothing circuit section 21 is arranged so as to straddle both sides, and as the distance between the rectifying and smoothing circuit section 21 and the switching circuit section 22 is close in this way, noise is generated. It's getting harder to do.

The choke coil 26 and the capacitor 27 are arranged in different sections. Furthermore, the preheating control circuit section 25 is arranged as a high-prip 1' integrated circuit so as to straddle both sides where the choke coil 26 and the capacitor 27 are arranged.
Since the Chiroku coil 26 and the capacitor 27 of the resonance circuit section 23 on the 1 side are arranged in a well-balanced manner,
The wiring pattern from the resonant circuit section 23 to the output terminal 11 is not crowded, and the wiring pattern can be easily formed. Further, the power terminal 12 is provided in the center of the board 6, and the output terminal 11
are provided on the periphery of the board 6, the power supply line is formed on the inner periphery of the board 6, and the output power line is formed on the outer periphery of the board 6, thereby distributing the power lines. This makes it easier to form wiring patterns for power supply lines.
