Description

Description: TECHNICAL FIELD The present invention relates to a lighting device having a rapid start type discharge lamp ballast for two in-line lamps applied to a fluorescent lamp or the like.

[Background technology]

A typical example of a rapid start type discharge lamp lighting circuit for two series lights is shown in FIG. That is, L ₁ and L ₂ are fluorescent lamps connected in series, C ₁ is a phase advancing capacitor, C ₂ is a starting capacitor, C ₃ is a noise preventing capacitor, R is a resistor, and P is a thermal protector. , T is the ballast body.
Although the ballast body T is a single-winding type, it may be composed of a normal transformer.

As is clear from this circuit, the load is a fluorescent lamp
The L _1, L _2, to connecting leads (red line) 30 and 31 connected to the high voltage side lamp filament, lead (blue line) 32 and 33 connected to the low pressure side lamp filament, and a common lamp filament A total of six lead wires (yellow wires) 34 and 35 are required, and lead wires (white wire and black or brown wire) 36 and 37 for the power source which receives power from the power source are required.

Conventionally, there is built in integrally with the casing 5 diagram surrounded by a broken line portion ballast body T, the components such as a capacitor C ₁ -C ₃ as a serial 2 lamps rapid start type discharge lamp ballasts. FIG. 6 shows the first conventional example, in which lead wires 30 to 33, 36, 37 are drawn out from one end of the case 1 and lead wires 34, 35 are drawn out from the other end.

However, since the lead wires 30 to 37 drawn out from the case 1 hang around in a suspended state and their positions cannot be determined, the first conventional example has a drawback in that it is extremely difficult to automate the assembly into the instrument body. In addition, since it is necessary to prepare several types of lead wires 30 to 37 having different lengths depending on the location of the rapid start type discharge lamp ballast for two series lamps when assembled in the main body of the apparatus, the series 2 There is a drawback that the rapid start type discharge lamp ballast for lamps cannot be standardized. Further, when the device is arranged as shown in FIG. 8, in order to avoid the power supply hole 3 formed in the center of the device body 2 and the power supply terminal block 4 arranged in the vicinity thereof,
Case 1 of rapid start type discharge lamp ballast for two in-line lamps
Is deviated to one end side between the fluorescent lamps L ₁ and L ₂ arranged in parallel, and therefore four lead wires 30 to 33 are required to be longer than 1/2 of the total length of the device. In addition, 5 is a lamp socket. When arranged on the opposite side of the power supply hole 3 as shown in FIG. 9, the lead wires 34, 35 become long, and the lead wires 36, 37 are case 1 of the rapid start type discharge lamp ballast for two series lights. Since it goes to the opposite side, it requires an extra long ballast and the wiring becomes complicated.

On the other hand, as shown in FIG. 7, high-voltage terminals 6 and 7 are provided at both ends of the case 1 of the rapid start type discharge lamp ballast for two series lights.
(Corresponding to lead wires 30 and 31), low voltage terminals 8 and 9 (lead wires 32 and 3
3), common terminals 10 and 11 (corresponding to lead wires 34 and 35),
2nd with protruding power terminals 12 and 13 (corresponding to lead wires 36 and 37)
In the conventional example, compared to the first conventional example, since the lead wire is not suspended in the air, handling is easy and automation is relatively easy, and standardization of a rapid start type discharge lamp ballast for two series lights is possible. However, in addition to the drawback that the amount of the lead wires 30 to 37 used in the device arrangement shown in FIGS. 8 and 9 is wasted, there are 6 terminals 6 to 9, 12 and 13 on one end side. It is not easy to secure insulation between 6-9, 12, 13 and between case 1 and terminals 6-9, 12, 13 and it is difficult to automate soldering or assembly wiring on the device side.

As another conventional example, there is a bare series two-lamp rapid start discharge lamp ballast without case 1, but since it is necessary to attach a capacitor externally, it is necessary to separately provide a capacitor terminal, Therefore, the number of external terminals increases, and it is not easy to ensure insulation between terminals or between the case and terminals.

[Purpose of device]

An object of the present invention is to provide a lighting fixture that can easily secure insulation of a terminal group, reduce waste of the usage amount of lead wires, and can be easily automated.

7, a low voltage terminal 8, 9 and a common terminal 10, 11 and a lamp socket 5 connected by lead wires 30 to 35.

The rapid start type discharge lamp ballast for series 2 lights of this lighting equipment is constructed corresponding to the rapid start type discharge lamp lighting circuit for series 2 lights of FIG. 5, and includes the range shown by the broken line. Therefore, illustration of the ballast body and the capacitor is omitted. The case 1 is filled with a compound to fix the internal parts.

According to this embodiment, the power supply terminals 12 and 13 and the common terminals 10 and 11 are provided at one end of the ballast 1 ′ incorporating the rapid start type lighting circuit for series two lights including the capacitor, and the high voltage terminal 6 is provided at the other end. Since 7 and the low-voltage terminals 8 and 9 are provided, the terminal group is evenly distributed to both ends of the ballast 1 ', and the terminal group is not concentrated at one end, so that it is easy to secure the insulation of the terminal group. In addition, the ballast 1'is connected to the power source hole 3 at the center of the instrument body 2 and the instrument body 2
The power supply terminals 12 and 13 and the common terminals 10 and 11 toward the power supply hole 3, and the ballast 1 ′ and the power supply hole 3 are arranged.

Further, compared with the conventional case, the terminal group is evenly distributed to both ends of the ballast 1 ', and the wiring inside the device does not cross over or beside the ballast 1', which facilitates automation of the wiring inside the device.
Moreover, there is no fear of heat deterioration of the device wiring due to the ballast 1'which is a heating element, and the reliability of the device is enhanced.

That is, specifically explaining the function and effect of this embodiment, although FIG. 3 shows a state of being incorporated in the apparatus body, the high-voltage terminals 6 and 7 and the low-voltage terminals 8 and 9 at one end are a rapid start for two series lights. Type discharge lamp ballasts are located on one side of fluorescent lamps L ₁ and L ₂ arranged in parallel on both sides, and have common terminals 10 and 11 and power supply terminals.
12 and 13 are located on the other end side of the fluorescent lamps L ₁ and L ₂ and the power supply terminal block 4 side of the power supply hole 3, so that the lead wires 30 and 31 connected to the high voltage terminals 6 and 7, the low voltage terminal 8, Lead 3 connected to 9
2, 33, the lead wires 34, 35 connected to the common terminals 10, 11 and the lead wires 36, 37 connected to the power supply terminals 12, 13 are the lead wires 30 as compared with the case of FIG. 8 and FIG. ~ 37 wiring is minimized, the amount used is small and it is economical. High voltage terminal
By evenly distributing 6, 7, etc. to both ends of the case 1, it is possible to increase the terminal interval without increasing the size of the case 1, and it is easy to ensure insulation of the terminal group and facilitate automation. Further, since it is a terminal type, as compared with the method in which the lead wires 30 to 37 are drawn out from the case 1, it is possible to standardize a rapid start type discharge lamp ballast for two in-series lamps having different equipment arrangements.
Also not require an external capacitor C ₁ -C ₃ as compared to naked series 2 lamp rapid start type discharge lamp ballasts, also it becomes easy wiring work at the instrument in the integration.
