Abstract

PURPOSE:To divide the printed board in a stabilizer into two parts at the optimum condition by dividing it into a resonance circuit and the other part. CONSTITUTION:The part from a protective circuit 2 to an inverter circuit 6, and a load circuit 7 are divided, and the parts are mounted on a printed boards 1a and 1b respectively. By dividing the load circuit 7 from the other part, the wirings of the printed boards 1a and 1b can be made only by two crossovers 11. The number of parts on the load circuit 7 is few, but since L2, L3, C7, C8, and C9 are large size parts including choke coils and high voltage capacitors, the sizes are not short. Large (heavy) parts can be set on the short printed board 1b, a warp and a bending of the printed board 1b can be suppressed at the minimum, and it can bear a vibration and a drop.

The length L will be lengthened. In particular, in the case of a straight tube type fluorescent lamp, since the length L has a high degree of freedom, the length direction is often lengthened.

Since the printed circuit board is slender, it is easy to warp and is extremely vulnerable to vibration and drops. Even when components are mounted, the positional deviation occurs due to the warpage. The ballast has heavy parts such as choke transformers even though it is an electronic ballast, and solder cracks are likely to occur due to the deflection of the printed circuit board.

路が実装されるためである。The inverter circuit 6 converts the output of the smoothing circuit 5 into a high-frequency alternating current by turning on / off a switching element using a power source as a power source, and a load circuit (resonant circuit) turns on a lamp with a waveform close to a sine wave with little noise. It is what makes them. In particular, when it is used for a straight tube fluorescent lamp, it is generally arranged from the power source side to the lamp side with respect to the printed circuit board 1 as shown in FIG.

There is no distinction between the inverter circuit 6 and the inverter circuit 6. If the control unit is hybridized, it becomes complicated. On the other hand, in the case of the load circuit 7, only the resonance circuit is used, and the components are mainly choke coils or transformers and capacitors. Although a large space is required in terms of parts, in terms of wiring, the two lines from the inverter circuit 6 are the minimum required lines, and division is most efficient here.

In the case of dividing for mounting on the rectifier circuit 4, when dividing by the smoothing circuit 5, the inverter circuit 6, and the load circuit 7, the former becomes shorter than the length of the printed circuit board 1, and the latter becomes shorter. However, the printed circuit board 1 cannot solve the drawbacks caused by the warp of the printed circuit board 1 mentioned in the conventional example.

る。When the smoothing circuit 5 and the inverter circuit 6 are divided, the number of wirings such as the main circuit wiring, the control power supply, and the control wiring is large, and the wiring is close to the switching element. It is also susceptible to noise. Therefore, if the load circuit 7 is divided from the left side of the circuit diagram of FIG. 3 to the inverter circuit 6 as shown in FIG. 1, the wiring of the divided printed circuit boards 1a and 1b may be two by the crossover 11, It has the following advantages.

There is no. Large (heavy) components can be arranged on the short printed circuit board 1b, and warpage and deflection of the printed circuit board 1b can be reduced as much as possible, which is strong against vibration and dropping. FIG. 1 shows a layout diagram in which the printed circuit board 1 is divided into 1a and 1b in this manner and each component is mounted, and the illustrated component shows a large component in the circuit of FIG. Also, both printed circuit boards 1
The combined size of a and 1b is the length L of the ballast case.

Since the height H (FIG. 6) of the ballast is small, the electrolytic capacitor C 4 has an elongated dimension, and it is inefficient in terms of mounting to separate the smoothing circuit 5 from the inverter circuit 6. That is, the electrolytic capacitor C 4
