Description

[Detailed description of the invention] [Technical field of the invention] The present invention relates to a flashing guide light, and more specifically, an emergency flashing light source that automatically flashes in response to a specific signal in conjunction with automatic fire alarm equipment. Concerning built-in flashing guide lights.

[Prior art]

Conventionally, this type of guide light was developed, for example, in the 1980s.
It is disclosed in Publication No. 183587. Conventional guide lights, including this known guide light, are formed in accordance with common technical standards in the guide light equipment industry, and their basic structure is shown in FIG. In FIG. 1, 1 is a fluorescent lamp, 2 is a guide light main body, 3 is a lighting window for the fluorescent lamp 1 provided on the bottom of the main body 2 and is covered with a transparent cover, and 4 is a window for the main body 2. A blinking light source is provided with an opening at the bottom and is installed to protrude outside the main body through the opening. Reference numeral 5 designates a cup-shaped transparent cover that covers the protruding blinking light source 4.

In this conventional flashing emergency exit light, the fluorescent lamp is normally lit by a normal power source via a normal lighting device, and in the event of a power outage, the fluorescent lamp 1 is lit by an emergency power source via an emergency lighting device to illuminate the display panel 7 and obtain the specified illuminance stipulated by the Fire Service Act and the like by the light irradiated from the light-receiving window 3. On the other hand, when a specific electrical signal is received in conjunction with an automatic fire alarm system, the flashing light source 4 is turned on by a flashing device (not shown).
The flashing light makes the emergency exit light easier to notice. Conventionally, the main body 2 is box-shaped with four flat sides, and the flashing light source protrudes from the flat bottom surface, making it easily visible from all visual angles from directly below the main body to the horizontal in both the horizontal and vertical directions.

However, in the conventional flashing guide light, since the flashing light source 4 is mounted so as to protrude from the main body 2 as described above, an opening in addition to the lighting window 3 must be formed on the bottom of the main body 2. Since the transparent cover 5 for protecting the protruding flashing light source 4 also had to be attached, a large number of processing steps and a large number of parts were required. Further, since the light-transmitting cover 5 protrudes greatly, special care must be taken in handling the instrument so as not to damage it, and furthermore, the packaging box for the instrument becomes larger than necessary. Flashing guide lights are usually installed above the evacuation exit, but if there is a protrusion on the bottom of the device, it may get in the way of opening and closing the evacuation exit door, and they have various drawbacks. Ta.

[Summary of the idea]

The present invention was made in order to eliminate the drawbacks of the conventional flashing guide lights as mentioned above, and its features are that the bottom of the main body is approximately U-shaped in cross section, and that there is a lighting hole in the curved bottom surface and a light hole close to the bottom. Lighting holes are also provided on the end face of the main body, and the flashing light source is installed inside the main body so that it can be seen from any direction from directly below the fixture to horizontally without protruding from the main body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the flashing guide light of the present invention will be described in more detail based on an embodiment shown in the accompanying drawings.

2 and 3 show a blinking guide light 10 according to a first embodiment of the present invention. This blinking guide light 10 has a main body 11 consisting of a box-shaped frame with one surface completely open, and the main body 11 has a completely open part on one surface, that is, an elevational opening, which is transparent to indicate an evacuation exit. A sexual guidance display panel 12 is provided. The main body 11 is closed by end plates disposed at both ends of the frame, and the bottom 11c of the main body 11 is closed by end plates disposed at both ends of the frame.
is formed into a substantially U-shaped cross section.

Inside this main body 11, a fluorescent lamp 13
is arranged slightly above the U-shaped curved bottom part 11c, and above it is a V-shaped reflection plate 1.
4 is fixed to the top plate of the frame and suspended. A large number of slits 15 extending in a direction perpendicular to the longitudinal direction of the bottom portion 11c of the main body 11, which is curved in a U-shape, are formed to form a lighting hole A. Further, in the center of the bottom 11c, a base 16 is disposed between the fluorescent lamp 13 and the bottom surface of the bottom, and the base 16 is fixed at both ends to the opposing wall across the inside of the frame 11. A blinking light source 17, such as a xenon lamp, is attached to the lower surface and placed in the bottom, so that it can blink in conjunction with automatic fire alarm equipment or the like. In addition, end surfaces 11a and 11b of the main body 11
On the surface, a lighting hole B consisting of a plurality of slits 18 is formed in the lower part near the bottom of the main body 11. The reference numeral 19 indicates a lighting device and flashing device group fixed to the top plate of the main body 11 inside the V-shaped reflector 14, and this lighting device and flashing device group 19 is connected to the fluorescent lamp 13 The light source 17 is turned on.

According to the flashing guide light 10 of this embodiment, a fluorescent lamp 13 is housed at the bottom of the bag-like main body with a U-shaped cross section, and a flashing light source 17 is housed below the fluorescent lamp 13. 14 illuminates the display panel 14, and at the same time obtains the illuminance specified by the Fire Service Act below the guide light from the lighting hole A, and functions as a guide light during normal times and during power outages. In addition, the flashing light source 1 is linked to automatic fire alarm equipment and receives a specific signal.
7 is a lighting hole A and a lighting hole B that emit flashing lights in almost all directions within a range of approximately 90 degrees from directly below the vertical guide light to the horizontal direction (angle range shown by arrow 20 in Figure 3). irradiate.

4 and 5 show a blinking guide light 10' according to another embodiment of the present invention. Components in this guide light 10' that are similar to those in the guide light 10 of the embodiment shown in FIGS. 2 and 3 are given the same reference numerals, and their explanations will be omitted.

In this blinking guide light 10', the blinking light source 17 is composed of a high brightness elongated lamp, and the lamp extends in the horizontal direction with an angle α of about 45 degrees with the long axis of the fluorescent lamp 13 in the horizontal direction. installed. The other points are the same as the first embodiment shown in FIG.

According to this second embodiment, the flashing light source 17 that is linked to an automatic fire alarm system or the like and receives a specific signal is provided by the lighting hole A and the lighting hole B from just below the guide light in the vertical direction to approximately in the horizontal direction. At the same time, since the flashing light source 17 is installed at an angle of about 45 degrees in the horizontal direction, the apparent light emitting area from the end surface of the guide light is
It can be larger than when arranged parallel to the longitudinal direction of the main body.

In addition, in each of the above-mentioned embodiments, the fluorescent lamp 1
Although the fluorescent lamp 13 is placed at the bottom of the main body 11, the fluorescent lamp 13 may be placed at any position within the main body 11 as long as it is placed below the guide light and can obtain the illuminance specified by the law. Although the lighting holes A and B are grouped as slits, if the bottom cross section is U-shaped, a large opening may be formed as in the conventional case and this may be covered with a light-transmitting cover.

Furthermore, in the second embodiment, the flashing light source was arranged at an angle of about 45 degrees with respect to the horizontal direction, but since the purpose was to increase the apparent light emitting area from the end face, the inclination angle was set to 45 degrees. It is not limited.

According to each of these embodiments, in addition to the effects described below, the fluorescent lamp is housed at the bottom of the main body, and the display panel is illuminated with even brightness by the reflector, so that it is not possible to use the conventional method. In order to equalize the brightness of the display panel with direct light, it is possible to prevent the phenomenon that the depth of the main body becomes thick as a result of placing the fluorescent lamps away from the display panel, and it also has a very thin design. Can form an excellent flashing guide light. As a result, even if a U-shaped bottom is formed on the main body to accommodate a fluorescent lamp or flashing light source, the volume of the main body as a whole becomes small, so the flashing light source and translucent cover are further protruded from the large volume main body. The packaging box for the conventional guide light was larger than necessary and also required parts to prevent breakage of the translucent cover, but in this embodiment, the main body volume is small and there is no protruding part, so the packaging box is small and prevents breakage. It has the advantage that no special parts are required, the packaging material is inexpensive, and distribution costs are also low.

[Effect of idea]

As explained above, according to the present invention, the flashing light source is housed at the bottom of the main body with a U-shaped cross section without protruding, and the flashing light is emitted from the lighting holes A and B, so that it does not flash like the conventional method. There is no need to provide a transparent cover to protect only the light source, which reduces the number of parts, and there is no need to additionally process a large opening for the flashing light source to protrude. Since there is no protrusion, there is no need to take special care in handling. As a result, it has the basic function of making the flashing light that makes guide lights more noticeable and visible from almost all viewing angles from directly below to the horizontal direction, while also offering excellent design, ease of handling, and workability. We can provide flashing guide lights.
