DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to a first embodiment shown in FIGS.

FIG. 4 shows the entire lighting system for guiding the evacuation guidance route. In FIG. 4, reference numeral 50 denotes a corridor of a building designated as the evacuation guidance route. A large number of emergency evacuation guide lights 1 are buried along a guide direction A on a floor or a wall of the corridor 50 at predetermined intervals. Each of the guide light devices 1... Is sequentially blinked with a predetermined timing shifted in an emergency, and such blinking is displayed as if the light were traveling in the evacuation guidance direction.

Since such a guidance lighting system operates in an emergency, an external command signal transmitting device 60 for externally commanding the operation of the system in the event of an emergency is provided. In some cases, it is not expected to use a normal commercial power supply, so the emergency power supply 70 is used. The emergency power supply 70 is usually a battery and supplies a small power of, for example, about 12V.

Each of the guide light devices 1 is configured as shown in FIGS. That is, reference numeral 10 denotes a casing of the guide light device. The casing 10 is formed of a nonflammable material such as a metal plate, and is formed in a square box shape with an open upper surface. A front cover 11 is attached to the opening, and an opening for light transmission is formed in the center of the front cover 11.

The light diffusion layer 1 is provided at the opening of the casing 10.
A light-transmitting cover 12 made of a two-piece laminated glass having the number 3 is attached. The translucent cover 12 includes a holding frame 14.
The holding frame 14 is also formed of a nonflammable material such as metal. The light-diffusing layer 13 is provided on the upper surface (outer surface) of the light-transmitting cover 12, and the light-diffusing layer 13 is fitted into the light-transmitting opening of the front cover 11. In addition, 1
Reference numerals 5 and 16 denote rubber packings for sealing.

A reflecting plate 20 is provided at the center of the casing 10. As will be described later, the reflection plate 20 is formed in a substantially gutter shape by a high-purity aluminum plate or the like, and the upper end opening is fixed to the opening of the casing 10. In the reflection plate 20, for example, a U-shaped fluorescent lamp 30 is accommodated. The U-shaped fluorescent lamp 30 seals a filament electrode (not shown) at both ends of a U-shaped glass bulb 31, forms a phosphor coating on the inner surface of the bulb 31, and a predetermined amount of It is composed of mercury and a rare gas for starting.

Such a lamp 30 is provided in the casing 10.
It is arranged horizontally inside. That is, as shown in FIG. 2, the U-shaped fluorescent lamp 30 has a plane through which the central axis of the bulb 31 passes parallel to the bottom surface of the casing 10, and
As shown in the figure, the straight portions 32, 32 on both sides of the U-shaped fluorescent lamp 30 are installed so as to be in a posture perpendicular to the direction A of the guidance route.

Such a lamp 30 is provided in the casing 10.
Is electrically connected to a lighting control circuit housed in the lighting device. The lighting control circuit includes a starting circuit for the lamp 30 and a lighting stabilizing circuit 83 for stabilizing the lighting, a boosting circuit for controlling the boosting of the voltage supplied from the emergency power supply 70, and the boosting voltage to the lighting stabilizing circuit 83. There is provided a power supply circuit 82 for supplying and an operation command circuit 81 for controlling the lighting of the lamp 30 by operating the lighting stabilizing circuit 83 by a signal sent from the external command signal transmitting device 60.

In this embodiment, a printed circuit board 18 is provided on the bottom surface of the casing 10 with an insulating spacer 17 interposed therebetween.
A lighting control circuit such as a power supply circuit 82 and a lighting stabilization circuit 83 is mounted. In this case, these circuit components are arranged so as to surround other periphery except the end side of the lamp 30. That is, the power supply circuit 82 is arranged on one side of the lamp 30 as shown in FIG. 2, and the lighting stabilization circuit 83 is arranged on the other side of the lamp 30.
The operation command circuit 81 is arranged outside the bent portion of the lamp 30. For this reason, each component of the lighting control circuit is arranged so as to surround the lamp 30 in a dead space formed between the inner surface of the casing 10 and the outer surface of the reflector 20.

Such a guide light device 1 has a light source U
The use of the fluorescent lamp 30 in the shape of a letter makes it possible to obtain high luminous efficiency and high brightness while consuming a small amount of power, to irradiate a wider area, and to make the lamp smaller and more compact. Since the operation command circuit 81, the power supply circuit 82, the lighting stabilization circuit 83, and the like are accommodated in a dead space outside the reflection plate 20, the casing 10 can be reduced in size and size.

Incidentally, the reflection plate 20 has a configuration as shown in FIGS. That is, the reflection plate 20 is formed in a substantially gutter shape by a high-brightness aluminum plate or the like, and the reflection surface is divided into a plurality. That is, in the reflection plate 20, when the cross section is taken along a line parallel to the direction A of the guide path, as shown in FIG. 1, the first reflection surface 21 is formed in a portion close to the opening, and The second reflection surface 22 is formed in a region near the bottom following the second reflection surface.

The first reflecting surface 21 reflects the light emitted from the lamp 30 in an oblique direction with respect to the optical axis OO of the reflecting plate 20 as shown by an arrow a, and thus the opening of the casing 10 is formed. Then, the light is reflected so as to be directed diagonally forward, in other words, along the direction A of the guidance route. Further, the second reflection surface 22 reflects the light emitted from the lamp 30 in a direction parallel to the optical axis OO of the reflection plate 20 as shown by an arrow b, and straightly passes through the opening of the casing 10. The light is reflected so as to be directed forward, that is, in a direction perpendicular to the direction A of the guidance route.

FIG. 2 shows a cross section of the reflector 20 taken along a line BB perpendicular to the direction A of the guide path. That is, the end wall 25 of the reflection plate 20,
25 rises substantially vertically, so that the reflector 20
In the direction B perpendicular to the guiding direction A, the amount of light obliquely traveling is relatively small.

The operation of the guidance lighting system having such a configuration and the guidance light device 1 used therein will be described.
In the guidance lighting system shown in FIG. 4, when an emergency occurs, an operation command is issued from the external command signal transmitting device 60 to each of the guide light devices 1, and each of the guide light devices 1 is supplied from the emergency power supply 70. It flashes and lights according to the power that is applied. In this case, each of the guide light devices 1 is provided with an operation command circuit 81 by a command signal transmitted from the external command signal transmitting device 60.
Operates to operate the stable lighting circuit 83, so that the power of the emergency power supply 70 is supplied to the stable lighting circuit 83 via the power supply circuit 82, and thus the lamp 30 is turned on. Lamp 30
Is blinked by the control circuit incorporated in the power supply circuit 82 or the stable lighting circuit 83. When the lamp 30 lights up,
The light emitted from the lamp 30 is reflected directly and on the reflection plate 20 toward the opening, and is emitted to the outside through the translucent cover 12 and the light diffusion layer 13. At this time, the transmitted light is diffused by the light diffusion layer 13 to make the brightness of the entire surface of the transmission window substantially uniform.

A plurality of guide light devices 1 embedded in the floor or wall of the corridor 50 share a common emergency power source 7.
Since the light is flashed by the power of 0 and by the command signal sent from the external command signal transmitting device 60, the light flashes so that the light sequentially advances in the evacuation guidance direction A.
The guidance direction A is displayed. Therefore, a person who seeks evacuation is guided to a safe place by proceeding in the direction A in which the light moves.

In this case, the light emitted from the lamp 30
Is reflected in the direction shown by the arrow a, that is, obliquely along the guiding direction A through the opening of the casing 10. However, since the light diffusion layer 13 has a property of diffusing light to be transmitted, the light traveling in the above-described oblique direction is also diffused temporarily. The amount of light in the direction can be increased. Therefore, when the guide light device 1 is viewed obliquely from the front, the brightness is improved, and the guide light device 1 is easily found. Therefore, the guidance function is improved.

A part of the light emitted from the lamp 30 is reflected straight forward by the second reflecting surface 22 as shown by the arrow b. The evacuation person who is also guided at a high angle and reaches the front of the guide light device 1 by being guided obliquely from the front is
After confirming the guide light device 1, the user can head in the direction of the next guide light device 1, and the visibility is improved.

Further, as shown in FIG. 2, since the end walls 25, 25 of the reflecting plate 20 rise substantially vertically, in the direction B perpendicular to the guiding direction A, the amount of light obliquely traveling is relatively small. Is becoming less. In other words, even if light is emitted obliquely to the direction intersecting the guiding direction A, the guiding effect is small, so that the light amount in such a diagonal direction can be reduced and the light amount along the guiding direction A can be increased accordingly. Therefore, the induction effect is further enhanced.

The present invention is not limited to the first embodiment, and various modifications are possible. That is, in the case of the first embodiment, since the light traveling toward the rear side of the lamp 30 is reflected at the bottom of the reflector 20 and returned to the lamp 30, there is a problem that the light cannot be used effectively. On the other hand, in the second embodiment shown in FIG. 5, a third reflecting surface 23 is formed on the bottom of the reflecting plate 20 facing the rear surface of the lamp 30, and the light emitted from the lamp 30 is reflected by the third reflecting surface. The light is reflected by the surface 23 and is reflected toward the first reflecting surface 21 or the second reflecting surface 22 or both the reflecting surfaces 21 and 22.

In this manner, the light traveling toward the back side of the lamp 30 is reflected by the third reflecting surface 23, and as shown by the arrow c, the first reflecting surface 21 or the second reflecting surface 22 or these two. Since the light is reflected toward both reflecting surfaces 21 and 22,
The light reflected in the first reflection surface 21 or the second reflection surface 22 again can increase the amount of light traveling in the a direction or the direction of the b direction. Therefore, the luminance increases and the efficiency of the device improves.

The first embodiment and the second embodiment are as follows.
Although the example in which the U-shaped fluorescent lamp 30 is placed horizontally as the light source is shown, the present invention may use a straight tube-type fluorescent lamp as the light source, and such a straight tube-type fluorescent lamp is used. Examples are shown in FIGS. In other words, the third
In the embodiment, the straight fluorescent lamp 301 is disposed on the optical axis OO.
Are arranged such that the lamp axes intersect, and the reflecting plate 20 has a first reflecting surface 21 that reflects the reflected light obliquely with respect to the optical axis OO. In the case of such a configuration, a part of the light emitted from the lamp 301 is reflected by the reflection surface 21, travels in the direction of arrow a, and is emitted obliquely forward of the housing 10. Therefore, visibility from diagonally forward along the guidance direction A is improved. It should be noted that the light directly emitted from the lamp 301 goes straight to the front of the housing 10 and there is also light due to the diffusion effect of the light diffusion layer 13, so that the light does not become completely dark when viewed from the front. .

However, in order to supplement the brightness of the front, it is better to provide a second reflecting surface 22 in addition to the first reflecting surface 21 as in the fourth embodiment shown in FIG. The first reflecting surface 21 reflects light emitted from the lamp 301 in an oblique direction as indicated by an arrow a, and the second reflecting surface 22 reflects light toward the front as indicated by an arrow b. That is, this embodiment has the same function as the embodiment shown in FIG. 1, and the example of FIG. 1 is a case where the U-shaped fluorescent lamp 30 is placed horizontally, whereas the present embodiment is a straight tube. This is a case where the shaped fluorescent lamp 301 is placed horizontally.

Further, the fifth embodiment shown in FIG.
This is an example in which a third reflecting surface 23 is further added to the reflecting surface 21 and the second reflecting surface 22 of FIG. The third reflecting surface 23 is the lamp 3
01 is reflected toward the first reflecting surface 21 or the second reflecting surface 22 or both reflecting surfaces 21 and 22 as indicated by an arrow c. In this case, the same operation as in the second embodiment shown in FIG.

Further, the present invention can be implemented in a case like the sixth embodiment shown in FIG. This embodiment is based on U
The U-shaped fluorescent lamp 30 is disposed vertically, that is, a plane passing through the bulb axis of the lamp 30 is arranged perpendicular to the bottom surface of the casing 10, in other words, along the direction of the optical axis OO. The straight portions 32a and 32b of the lamp 30 are arranged so as to intersect with the direction of the guidance route,
0 has a first reflecting surface 21 and a second reflecting surface 22. Then, one straight portion 3 of the U-shaped fluorescent lamp 30
2a is reflected by the first reflecting surface 21 so as to face diagonally forward as indicated by an arrow a, and light emitted from the other linear portion 32b is reflected by the second reflecting surface 22. As shown by the arrow b, the light is reflected straight forward. In other words, the light of the two linear portions 32a and 32b of the U-shaped fluorescent lamp 30 is divided into functions in the oblique direction and the straight traveling direction, respectively, thereby equalizing the light amounts in the oblique direction and the front direction. .

In each of the above embodiments, the end walls 25, 25 of the reflecting plate 20 are made vertical, and the light radiated in an oblique direction included in a plane parallel to the direction A of the guide path and perpendicular to the installation surface. Of the light emitted in the diagonal direction included in the plane perpendicular to the installation surface in the direction B perpendicular to the guide path, but the present invention is not limited to this, and the light intensity along the direction A of the guide path is The luminous intensity of the light emitted obliquely may be higher than the luminous intensity of the light emitted only in a direction perpendicular to the guiding path A.

[0035]

According to the present invention as described above, according to the present invention, avoidance
In each of the guide light device for setting a difficult guide route and the lighting system for guide, the light emitted from the lamp is strongly reflected in the direction of the guide route by the reflector, so that the guide route The intensity of light radiated along the direction is higher than the luminous intensity of light radiated in other directions, and the brightness increases when the guide light device is viewed from a distance, so that visibility is improved. For this reason, the induction effect is improved.
