Description

[Detailed Description of the Invention] This invention relates to a circular hanging type fluorescent light fixture that is also equipped with an emergency power supply unit that uses a storage battery as an emergency power supply.

Conventionally, there has been no circular hanging type fluorescent light fixture that can be used in conjunction with a fluorescent lamp that is turned on for general illumination during normal times, but also turned on for emergency purposes in the event of a power outage. Built-in type lamps are generally used, which turn on an incandescent lamp as an emergency light source using a built-in storage battery in the event of a power outage.

This invention can be applied to both the above-mentioned combined type and built-in type fluorescent lamp equipment, and includes an emergency lighting unit, that is, an emergency power supply unit in the combined type, and an emergency power supply unit and an emergency lighting unit in the built-in type. An object of the present invention is to provide a circular hanging type fluorescent lamp fixture that allows an emergency lighting unit to work efficiently by reducing adverse thermal effects on incandescent light bulbs and lamp sockets, and that makes the structure of the fixture easy to process and assemble. It is.

Conventionally, there was no circular hanging type fluorescent light fixture that was combined with a built-in battery, so we will introduce an example of a built-in type with a built-in battery.
This will be explained based on FIG.

In the device shown in FIG. 1, a star socket 2, a charger 3, a ballast 4, a socket stand 5, and a lamp socket 6 are housed in a case 1 of a device body 23, and these are covered with a reflective plate 9 that has been greatly drawn. A battery case 8 is attached to the lower surface of the reflector 9, and a storage battery 7 is housed within this case 8.

Furthermore, a fluorescent lamp 1 disposed on the outer periphery of the instrument body 23
The periphery of 2.13 is covered with a shade 10 fixed to the instrument body 23 and made of a translucent material, and the lower part thereof is open.

With this configuration, the heat Q generated in the ballast 4
4 increases the temperature of the air inside the case 1 and heats the charger 3 along with heat radiation.

Also, the heat generated from the fluorescent lamps 12.13 Q12. q
13 heats the reflector 9 and enters the case 1,
This causes the temperature of the internal air to rise.

The amount of heat generated from the ballast 4 and the fluorescent lamp 12.13 is finally combined with the combined amount of heat Q released from the surface of the case 1, and the amount of heat generated from the fluorescent lamp 12.13 directly flowing out of the case from the shade 10. The amount of heat is QL.

However, the charger 3, which constitutes a part of the emergency lighting means, has a built-in relay that has a power failure detection function, and placing it in a high temperature atmosphere is not desirable in order to efficiently demonstrate its performance. .

Therefore, it is better to prevent the charger 3 from being affected by the heat Q4 of the ballast 4 and the heat Q1 and Q13 of the fluorescent lamps 12 and 13 as much as possible.

In addition, in the structure of the device shown in FIG. 1, the reflector 9 is processed to be large by deep drawing, and a large number of parts are housed inside the case 1 and the reflector 9, and the heat capacity inside the case 1 is increased. Therefore, a large amount of materials and processing costs are required due to the shape of the reflector plate 9.

The device shown in FIG. 2 has a case 1 that is wider and larger than the one shown in FIG. In addition to being stored at a height, the battery case 8 and storage battery 7 are also stored together.

This arrangement is less thermally efficient than the apparatus of FIG.

That is, since the case 1 is made wider, the reflector plate 9 must also be made wider, and the heat Q12. of the fluorescent lamps 12.13.
The area that absorbs Q13 increases, and not only the charger 3 but also the storage battery 7 is heated.

This type of storage battery 7 is usually a nickel cadmium storage battery, and due to its chemical properties, it
They are designed to be used within a certain range of temperatures, and if they are exposed to higher temperatures, their lifespan will be extremely shortened or they will no longer function properly.

Thermal protection of the battery 7 is therefore much more expensive in the construction of the device of FIG. 2, since the battery 7 is much more sensitive to heat than the charger 3.

FIG. 3 shows a fluorescent light fixture previously proposed by this inventor, which is an improvement over the ones shown in FIGS. 1 and 2.

This device stores only a ballast 4 and a starter socket 2 inside a case 1 like a general lighting device of this kind, and a charger 3 can be attached to the bottom surface of a reflector 9 by making a charger case 11 separately. be.

The charger case 11 also serves as a socket stand 5, and a storage battery 7 is arranged around the charger case 11 and covered with a battery case 8.

In the structure of the device shown in FIG. 3, the charger 3 is connected to the ballast 4.
This is advantageous because it is hardly affected by the heat of fluorescent lamps or fluorescent lamps.

However, although the amount of heat from ballast 4 is not large,
A transformer built into the charger 3 also generates heat, and this heat Q3 warms the surrounding storage battery 7.

Also, since the storage battery 7 is located around the charger 3,
As the storage battery 7 becomes closer to the fluorescent lamp 13, the influence of its heat Q13 increases.

Therefore, in the structure of the device shown in FIG. 3, the reflector plate 9 is not particularly large and the workability has been improved, but the above-mentioned thermal problem has not yet been satisfactorily solved.

In addition, in the fluorescent lamp equipment shown in Figures 1 to 3,
Thermal problems are compared for cases in which case 1, reflector 9, and shade 10 are all provided with heat countermeasures such as ventilation holes.

Therefore, in this invention, we have further improved the idea previously proposed by the creator of this invention, shown in Figure 3, by optimizing the positions of the charger, storage battery, and fluorescent lamp, and reducing the amount of heat exerted on the charger and storage battery. This is to ensure that they operate efficiently by eliminating negative effects on the environment.

Examples of this invention will be described below with reference to the drawings.

FIG. 4 shows an embodiment of this invention, in which this invention is applied to a combination type fluorescent lamp device that uses an inverter to turn on the same fluorescent lamp as normally used during a power outage.

In this device, the case 1 of the device main body 23 is the same size as that of a general fluorescent lamp device of this type, and houses a ballast 4, a starter socket 2, and a pull switch 17 inside. The lower surface of the case 1 is covered with a reflector 9 having the same size as that of the light fixture.

An inverter 15 and an inspection switch 1 are provided on the bottom surface of the reflector 9.
A power supply case 16 having a built-in power supply unit 4 is configured separately from the reflector plate 9 and fixed therein.

In addition, the internal wiring to the ballast 4 and power supply is connected to the connector 20.
It is possible to connect with.

The storage battery 7 is housed in a battery case 8 and is detachably fixed to the lower surface of the power supply case 16.

The power supply case 16 and the inverter 15 built therein constitute a power supply device 21, and this device 21, the storage battery 7, and the storage battery case 8 constitute an emergency lighting unit 22.

As is clear from the comparison with the one in FIG. 3, the heat flow of the fluorescent lamp apparatus constructed as described above is the
is the fluorescent lamp 1 from the case 1 of the fixture body 23 to the ceiling side.
The heat Q1□ of 2 passes through the reflector 9 and the shade 10 and goes out of the device.
Part of the heat Q13 of the fluorescent lamp 13 flows into the case 1 through the reflector 9, and the rest flows out of the appliance through the reflector 9 and the shade 10, and the heat Q15 of the transformer in the inverter 15 is reflected directly above. Warm the plate 9 and move it into the case 1.

Therefore, the adverse thermal effects of the ballast 4 and the fluorescent lamps 12, 13 are hardly exerted on the emergency lighting unit 22, that is, the inverter 15 constituting the emergency power supply unit.

Furthermore, compared to the one in FIG. 3, the storage battery 7 is located below the power supply case 16, so it does not receive heat from the transformer of the inverter 15, and is located at a greater distance from the fluorescent lamp 13. , which also reduces the amount of heat being heated.

In this embodiment, the reflector 9, the power supply case 1
By making holes 9a, 16a, and 8a in the center of the battery case 6 and the battery case 8, and passing the pull ring 19 of the pull switch 17 and the pull ring 18 of the inspection switch 14 through these holes, air circulation is improved and heat is removed. conditions are even better.

In particular, since a hole 9a passing through the center of the reflector plate 9 is provided, the inside of the power supply case 16 is communicated with the interior surrounded by the case 1 and the reflector plate 9 through this hole 9a, and the heated air is directed upward. As a result, even if the air inside the power supply case 16 is heated by the heat of the transformer of the inverter 15, this air flows into the interior surrounded by the case 1 and the reflector 9, and the gap between these joints etc. is discharged to the outside from
The ambient temperature of the inverter 15 is kept low, and the influence of the heat of the inverter 15 is eliminated.

Figure 5 shows another embodiment of this invention, in which this invention is applied to a built-in fluorescent light fixture in which an incandescent light bulb for emergency lighting and a lamp socket are built into the power supply unit. .

In this embodiment, a charger 3 is housed in the power supply case 16, and a lamp socket 6 is provided on the bottom surface of the power supply case 16.
It has been established.

The embodiment shown in FIG. 5 configured as described above can obtain almost the same effect as that shown in FIG. 4 only by replacing the inverter 15 of the embodiment shown in FIG. 4 with the charger 3. .

That is, the charger 3 is equipped with a ballast 4 and a fluorescent lamp 12.1.
The thermal influence of 3 is almost gone, and storage battery 7
is located below the charger 3, the adverse effects of the heat from the transformer of the charger 3 and the heat from the fluorescent lamp 12. As the heated air inside flows upward through the hole 9a of the reflector 9, the ambient temperature of the charger 3 is kept low, and the adverse effects of the heat of the charger 3 are eliminated.

In addition, except for the above-mentioned in the embodiment shown in FIG.
Since the structure is substantially the same as that shown in FIGS. 3 to 3, the same or corresponding parts are given the same reference numerals in FIG. Since it has the same configuration as that shown in FIG. 4, the same or corresponding parts are given the same reference numerals in FIG. 5, and their explanations will be omitted.

In this invention, as shown in FIG. 6, the power supply case 16 and the battery case 8 are integrated, and the storage battery 7
It is also possible to form an opening large enough to allow the battery to pass through, fit a shallow lid 24 thereon, and place the storage battery 7 on top of this lid 24 for storage. You can expect it.

As explained above, according to this invention, the lower surface of the instrument body that houses the ballast is covered with a reflector having a through hole in the center, and a separate emergency lighting unit is attached to the lower surface of this reflector. Since the storage battery of this unit is installed below the power supply device that has an inverter or charger, the inverter or charger is hardly exposed to the heat of the ballast or fluorescent lamp, and the ambient temperature of the inverter or charger is lower than that of the inverter or charger. It is possible to suppress high temperatures caused by the heat of the transformer, etc., and the storage battery is not exposed to the heat of the transformer of the inverter or charger, and is less likely to be heated by the fluorescent lamp. This allows the emergency lighting unit to operate reliably and efficiently, and there is no need to increase the size of the case or reflector of the device itself. This has the effect of providing a lowered type fluorescent device.
