Description

[Detailed Description of the Invention] This invention relates to a xenon lamp mounting structure, and more particularly to a xenon lamp mounting structure in a guide light device that provides emergency guidance by flashing light in conjunction with an alarm sound in the event of an emergency such as a fire.

Guide light devices for evacuating people in the event of an emergency such as an earthquake or fire have a visual arousal means using light as well as means for arousing an emergency situation using a warning sound.

However, in conventional emergency lighting systems, the visual arousal means is a constant light that does not flicker, such as an incandescent bulb or fluorescent light. There was a shortcoming that it was not sufficient to guide people safely and quickly when an emergency situation occurred. Furthermore, when an incandescent light bulb is used, a socket is required for the installation structure, making the entire device large, and the life of the light source is short due to the inherent characteristics of the light bulb, resulting in poor reliability.

This idea was made in view of the above circumstances,
To provide a xenon lamp mounting structure in a guide light device which employs a small and efficient xenon lamp as a light source of the guide light device, uses flash light as a visual arousal means, and improves heat dissipation effect.

This idea was developed by bending two highly rigid wires of different lengths to form electrode abutting parts on each conductive wire. Connect it upright to the output terminal on the board on which the drive circuit is mounted, and elastically sandwich both electrodes of the xenon lamp by the electrode contact portions of the two conductive wires, and solder both electrodes. The present invention is characterized in that a xenon lamp drive circuit and the xenon lamp electrode are connected.

Figure 1 is a diagram showing the xenon lamp mounting part that is an embodiment of this invention, Figure 2 is a diagram showing the conductive wires used in the above-mentioned mounting part, and Figure 3 is a guide lamp with a built-in board shown in Figure 1. FIG. 2 is an external view of the device.

The conductive wire 1 shown in FIG. 2 is formed from a single wire having a circular cross section that has high rigidity and good electrical and thermal conductivity. An electrode abutting portion 1a is formed by bending approximately the center of one wire into two halves with a curvature slightly smaller than that of a rod-shaped electrode of a xenon lamp. Two substrate standing portions 1B are formed at both ends of the wire by bending the wire to a length necessary to vertically stand the wire bent in half on the substrate. The electrode contact portion 1a of the conductive wire 1 and the substrate upright portion 1 formed in this way
The length b from the bending point is the separation distance between the center position of the xenon lamp, which is integrally fixed on the substrate, and the substrate surface.

Referring to FIG. 1, the xenon lamp installation procedure will be explained. First, two conductive wires 1 of different lengths are connected to two output terminals 2b on the back side of the board 2, which has a xenon lamp drive circuit (not shown) that operates in response to an emergency signal mounted on the front side. Standing part 1b
Attach by soldering. The reason for using the two conductive wires 1 having different lengths is to provide directionality to the flash light from the xenon lamp after mounting. Next, a xenon lamp 3, which is a generally cylindrical glass tube filled with xenon gas and equipped with rod-shaped electrodes 3a at both ends, is held between the electrode abutting portions 1a of the conductive wire 1. Conductive wire 1
Since the curvature of the electrode contact portion 1a is slightly smaller than that of the rod-shaped electrode 3a, elastic deformation occurs due to the contact of the electrode 3a, and a sufficient clamping force to hold the xenon lamp 3 is obtained. Further, this clamping force can also be obtained by making the distance between the two conductive wires 1 fixed on the substrate 2 slightly shorter than the distance between the electrodes 3a of the xenon lamp 3. Then, the sandwiched electrode 3a and electrode contact portion 1a are soldered. This means that the xenon lamp 3 is integrally fixed onto the substrate 2 and electrically connected to the xenon lamp drive circuit. Further, on the glass tube of the xenon lamp 3, a control line 3c is spirally wound between the tips of the two electrodes 3a for smoothing the transition from glow discharge to arc discharge at the time of starting. The control line 3c and the output line 2c of the xenon lamp drive circuit are connected after the xenon lamp 3 is integrally fixed to the substrate 2 and the work becomes easier.

The substrate 2 to which the xenon lamp 3 is fixed as described above is fitted into the case 4 of the guide light device as shown in FIG. 3, and fixed with screws or the like. The case 4 has a trapezoidal square shape as a whole, and has a small hole 4a in one place for emitting a warning sound such as an alarm.The protruding part of the xenon lamp 3 has a hemispherical protection colored in a danger display color. A cover 4b is attached. In addition to the board 2, the case 4 also includes electronic components (not shown) necessary for controlling the guide light device.

Therefore, in the guide light device having the above structure, even if the xenon lamp 3 is blinked for a long time in an emergency, the xenon lamp 3 is firmly fixed on the board 2 by the conductive wire 1 with an appropriate spacing. The heat dissipation effect is good and the solder joints will not melt. Therefore, there is no effect on electronic components that are sensitive to heat, and there is no decrease in reliability even if the emergency continues for a long time.

In addition to the conductive wire 1 shown in FIG. 2, the conductive wire 1 having a large rigidity used in the mounting portion of the mounting structure of this invention may have the shape shown in FIG. 4. Figure 4A shows the electrode contact area 1a after one rotation when bending the wire.
is made into a ring shape, and B is the board standing portion 1b.
C is only in one place, and C is the electrode contact part 1.
In order to make a into a ring shape and increase the heat dissipation effect, wire rods are folded and overlapped multiple times.

Since the conductive wire is a wire rod, it can be easily bent to form the electrode abutting portion, and has the advantage that material costs and processing costs can be reduced.

As described above, according to this invention, people can be guided safely and quickly in an emergency by using a powerful flash of light from a xenon lamp.
In addition, to attach a xenon lamp, two highly rigid wires are bent to form an electrode abutting part, and each electrode of the xenon lamp is elastically sandwiched between the electrode abutting parts and temporarily fixed. After this, the xenon lamp is fixed with solder, making it easy to perform soldering work, and the xenon lamp can be firmly fixed. Since the xenon lamp is securely fixed by the elastic force of the wire (conductive wire) and the solder, it has durability against large vibrations and shocks caused by earthquakes and the like. In addition, since the xenon lamp is fixed to the tips of two simple conductive wires that stand up on the board, there is no need for insulated lead wires or mounting hardware, and the heat dissipation effect is very good, making it ideal for guiding light devices. This has the advantage of improving overall reliability. Moreover, since it uses a xenon lamp as the light source,
Since the guide light device can be made smaller and the life of the light source is extended, maintenance of the guide light device becomes easier.
