Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an emergency lighting device installed on the lower surface of a ceiling in a long place such as a corridor.

[Prior Art] FIG. 6 shows a fixture body 1 of a conventional emergency lighting fixture, which is of a battery built-in type. A general light bulb (100V, 40 to 60W) that is lit by an AC power source connected to the terminal block 3 is used as the constant light 2, and the emergency light 4 is a battery lighting system with a low voltage such as 12V, and the lamp is 12V. I used a mini halogen lamp such as (20-40W). The power input is taken from the general power line circuit, and in an emergency, when the power is turned off, the emergency light 4 is turned on by the battery by the switching device 5 built in the instrument body 1 '. An inspection switch 6 is suspended in the instrument body 1 '.

The problems of the instrument body 1'include the following. That is, since the continuous lamp 2 is an incandescent lamp, it consumes a large amount of electric power and is not energy-saving, and it requires two kinds of lamps, which is uneconomical. Also, in maintenance management, 2
There was the problem of having to prepare different types of lamps.

Therefore, as shown in FIG. 7, a method has been developed in which a fluorescent lamp 7 is used and the fluorescent lamp 7 is turned on at all times and in an emergency. Of the many general lighting fixtures installed, there are many cases where emergency lighting fixtures are installed in this way and turned on. In FIG. 7, the instrument body 1'includes a ballast 8, a battery 9, a switching device 10 for switching between normal and emergency states, and the like.

Next, when the fluorescent lamp is used as an emergency light, there are the following problems. In other words, because the light source is larger than an incandescent emergency light, it is difficult to control the light with the reflector, and a wide range of lighting is needed (in the case of a fluorescent lamp, the floor illuminance is 21x. Good as an emergency light)
Is hard to do. That is, in the case of emergency lighting of a long place such as a corridor, the straight tube lamps may be arranged as shown in FIGS. 9 and 11. When the longitudinal direction of the straight tube type fluorescent lamp 7 is installed in the same direction as the longitudinal direction of the corridor as shown in FIG. 9, the device main body 1 is provided so that a light distribution curve that does not spread so much in both sides of the corridor is obtained. As shown in Fig. 8 (a), both inner surfaces of the instrument body 1'are formed as vertical surfaces, and as shown in Fig. 8 (b), both end inner surfaces of the instrument body 1'are R surfaces. The formed light is used, and the overall light distribution state is as shown in FIG.

Further, as shown in FIG. 11, when the straight tube type fluorescent lamp 7 is installed in a direction orthogonal to the longitudinal direction of the corridor, the main body of the device is provided so that a light distribution curve spreading in the longitudinal direction of the corridor is obtained. As 1 ', as shown in FIGS. 10 (a) and 10 (b), an instrument body 1'whereinside inner surfaces of both sides are formed by R surfaces, and both inner sides of the instrument body 1'are formed by vertical surfaces are used. The overall light distribution is as shown in FIG. However, since the fluorescent lamp 7 is large in both, the light distribution curve
The 21x range doesn't grow that much, so it's not very effective as an emergency light. Further, the installation interval of the instrument body 1'becomes shorter than the light distribution curve of the fluorescent lamp 7.

Here, when the mini halogen lamp 11 is used as an emergency light in consideration of such a form for a corridor light, the light distribution curve thereof extends considerably laterally as shown in FIG. 12 (a). This is because the mini-halogen lamp 11 is very small and therefore the light is controlled by the reflector 12. Therefore,
As shown in FIG. 13, if the apparatus main body 1'using the mini halogen lamp 11 is installed in the corridor, the number can be reduced as compared with the above case.

[Problems to be Solved by the Invention] The present invention has been provided in view of the above points, and is an emergency lighting system that makes use of both the energy saving feature of a fluorescent lamp and the light distribution feature of a mini halogen lamp. The purpose is to provide a device.

[Means for Solving the Problems] [Operation] The present invention is an emergency lighting fixture installed in a long place such as a corridor, and includes a plurality of bulbs for emitting light, and the bulbs are arranged in a line. The fluorescent lamp and the reflecting surface have a substantially arcuate cross-section and are arranged so that the reflecting surface faces the arrangement surface of the bulb. The light from the bulb is below the bulb and the arrangement surface of the bulb. Since a reflecting plate extending in a direction orthogonal to the above is installed in the main body of the fixture arranged on the lower surface of the ceiling at the above-mentioned longitudinal place, the reflecting plate faces the arrangement surface of the bulb to arrange the light from the bulb. The light distribution of the fluorescent lamp is extended to the side like a mini halogen lamp by reflecting the light toward the lower side in the direction orthogonal to the above.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 4, the fluorescent lamp 15 used in this embodiment has four cylindrical bulbs 17 standing on a base 16, and the bulbs 17 are arranged in a line. Base on both ends of valve 17
A filament 18 is provided on the 16 side, and both filaments
The inside of the bulb 17 between 18 is used as a zigzag discharge path. A lamp pin 19 is provided on the other side of the base 16. still,
The arrow in the bulb 17 in FIG. 4 indicates the direction of discharge. As shown in FIG. 3, a battery 21, a switching device 22, a ballast 23 and the like are arranged on the lower surface of the top plate of the case 20 of the instrument body 1 to which the fluorescent lamp 15 is attached. Further, a fixed base 24 is attached from approximately the center of the lower surface of the top plate, and a socket 25 for mounting the fluorescent lamp 15 is attached to the fixed base 24.
The reflector plate 26 that reflects the light from the fluorescent lamp 15 is a fluorescent lamp.
They are arranged so as to face the array surface of the 15 valves 17. That is, as shown in FIG. 3 (b), the bulb of the fluorescent lamp 15
The reflecting surface of the reflecting plate 26 on the side of the arrangement direction of 17 is parallel to the bulb 17, and is not a reflecting surface that allows light to have a desired light distribution curve. The reflection surface of the reflection plate 26 facing the arrangement surface of the bulbs 17 of the fluorescent lamp 15 has an arc-shaped cross section as shown in FIG. The light distribution curve is extended to the lower side of the direction.

The independent light distribution curve of the fluorescent lamp 15 is a curve as shown in FIG. 2, and naturally there are many light beams in the plane direction, that is, in the direction orthogonal to the array surface. That is, the characteristic of the fluorescent lamp 15, the direction of good light emission is the light control surface of the reflection plate 26,
The reflector plate 26 allows the light of the fluorescent lamp 15 to fly laterally as far as possible.

FIG. 1 shows the installation state of the fixture body 1, which is installed on the lower surface of the ceiling with the light distribution direction of the bulb 17 of the fluorescent lamp 15 orthogonal to the longitudinal direction of the corridor. Therefore, the light emitted from the fluorescent lamp 15 is laterally reflected by the reflecting plate 26, its light distribution characteristics substantially match the longitudinal direction of the corridor, and the light distribution is set at an interval longer than that of the mini halogen lamp. It is short, but longer than a straight tube fluorescent lamp.

FIG. 5 shows a case where the fluorescent lamp 15 is arranged sideways,
Even in this case, the same effect as above can be obtained. Further, by making the cross section of the reflection plate 26 substantially heart-shaped, the angle of light in the same direction can be obtained.

[Advantages of the Invention] As described above, the present invention is an emergency lighting device installed in a long place such as a corridor, which includes a plurality of bulbs for emitting light, and the bulbs are arranged in a row. , The cross-sectional shape of the reflecting surface is formed in a substantially arc shape, and the reflecting surface is arranged so as to face the array surface of the bulb, and the light from the bulb is below the bulb and is orthogonal to the array surface of the bulb. Since the reflecting plate extending in the direction is installed in the instrument main body arranged on the lower surface of the ceiling at the longitudinal place,
By reflecting the light from the bulb to the lower side in the direction orthogonal to the arrangement surface by facing the arrangement surface of the bulb by the reflection plate, the light distribution of the fluorescent lamp can be laterally extended like a mini halogen lamp, Further, by using the fluorescent lamp, it is possible to save energy.
Therefore, both the energy saving feature of the fluorescent lamp and the light distribution feature of the mini halogen lamp can be utilized.
