DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security light for displaying a dangerous area such as a construction site at night.

[0002]

2. Description of the Related Art Conventionally, there has been known a technique of blinking light with a security light in order to display a construction site, an accident site, traffic control, etc., and to show the existence of shops and facilities such as a drive-in. In order to make this light blink, a rotating light or a power source such as a neon lamp was turned on / off to make it appear to blink, but the light source has a service life and the rotating light drives the motor. Electric power is always required, and in consideration of these running costs, a light emitting diode (LED) has recently been used as a light source. As a technique using the light emitting diode, for example, there is a technique disclosed in Japanese Utility Model Laid-Open No. 4-117017, which inserts two power supply lines into a light-transmitting synthetic resin tube and emits light between the power supply lines. Diodes were connected and the polarity was switched on the power supply side to blink.

[0003]

Since the above-mentioned security light has a light-emitting diode housed in a tube, it can be turned on and off only at one place. It is necessary to arrange a large number of these tube-type security lights or lengthen the tubes, which increases costs. In the case where a light emitting diode is connected to the power supply line at regular intervals to form a tree of illuminations, one of them is, as shown in FIG.
・ Pull the cable sheath at the predetermined position of 1b to remove the conductor 4
a and 4b are connected to the lead wires 3a and 3b of the light emitting diode 2 by soldering, and this connection portion is integrally molded with a synthetic resin 5 to insulate and waterproof, and the light emitting diode 2 has directivity in the light emitting direction. Therefore, the light is covered with the translucent synthetic resin 6 so as to diffuse the light and scatter the light around. However, since the synthetic resin 5 for insulation is a hard resin, if the power supply line is pulled, it may be cracked or broken, and the insulation may be reduced. Is covered with the translucent synthetic resin 6, so that the number of assembling steps is increased.

[0004]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. That is, a light emitting diode is connected in parallel with a predetermined interval between two power supply lines, and the entire connection between the light emitting diode and the lead wire of the light emitting diode is connected in half.

Next, the operation will be described. That is, the entire connecting portion between the light emitting diode and the lead wire is made of a translucent light diffusing synthetic resin.
By the body to cover, performed insulating and waterproof simultaneously, semi
By covering the light emitting diode with the transparent light diffusing synthetic resin, the entire periphery of the light emitting diode can be illuminated, and the dangerous area at night can be easily recognized. Also hook
Depending on various places such as poles and fences
be able to.

[0006]

Next, an embodiment will be described. FIG. 1 is a perspective view of an embodiment in which a security light according to the present invention is connected to issue a warning at a fixed length, FIG. 2 is a front view of the security light of the present invention, and a partial plan view thereof, and FIG. FIG. 4 is a sectional view of an embodiment in which a light emitting diode and its periphery are covered with a light diffusing synthetic resin and further covered with a flexible synthetic resin, and FIGS. 5 to 7 show embodiments in which a security light of the present invention is provided. FIG.

Referring to the overall configuration in FIG. 1, a security lamp A, A... Of the present invention is connected to a pole 10 to distinguish it from a danger zone at a construction site or an accident site.
・ 10 ・ ・ ・ It is stretched between. The security light A is connected to the power supply line 11 in parallel at a predetermined interval.
Is connected to a power source 13 via a blinking device 12. The power source 13 is a battery or an AC power source,
When the security light A is an AC power supply using the light emitting diode 14 as a light source, the voltage is lowered so that a predetermined current flows. The blinking device 12 turns on and off the supplied power by a timer or the like at predetermined intervals to blink the power. When the light emitting diode 14 has a built-in blinking mechanism, the blinking device 12 is unnecessary. .

As shown in FIG. 2 and FIG. 3, the structure of the security light A is such that the cable sheath 11a is peeled off at predetermined positions of the two power supply lines 11, and the light emitting diode 14 is inserted between the conductors 11b. With the lead wires 15a and 15b of the light-emitting diode 14 spread out to both outsides, the main body of the light-emitting diode 14 is sandwiched between the conducting wires 11b and 11b, and while insulation is provided between the power supply lines having different polarities, The lead wires 15a and 15b are connected by solder 16. Actually, the light emitting diode main body is inserted by splitting a part of the two positive and negative bundled power supply wires, and the lead wires 15a and 15b are turned upside down on both side surfaces, and the main body and the conductive wire are adhered and fixedly connected. .
From the state in which the lead 15 of the light emitting diode 14 is connected to the power supply line 11, the light emitting diode 14 and the lead 1
5 and the conductors 11b and 11b are integrally covered with the light diffusing synthetic resin 20 or the flexible synthetic resin 21 at the same time, and at the same time, the security lights A are formed by providing the hooks 17 on the power supply lines 11 on both sides. The security light A is connected to a power supply line as shown in FIG.
11 are arranged at regular intervals .

The light diffusing synthetic resin 20 is a translucent resin, such as acrylic, polyethylene, polypropylene,
The light emitting diode 14 is made of polycarbonate or the like.
The light emitted from is diffused. The flexible synthetic resin 21 is a transparent resin and is made of vinyl chloride, a thermoplastic elastomer, or the like.
In the case of covering only with irregularities, as shown in FIG.
a is formed to have diffusivity. The light diffusing synthetic resin 20 and the flexible synthetic resin 21 are formed by injection molding, and the light diffusing synthetic resin 20 or the flexible synthetic resin 2 is formed.
1 is colored by mixing a coloring agent according to the application.

When the light-emitting diode 14 is covered only with the light-diffusing synthetic resin 20 depending on the shape and the size of the security light A, the lead wires 15a and 15b may be broken, or the lead wires 15a and 15b and the conductive wire 11b. 11b may be detached, and if it is configured to be covered with only the flexible synthetic resin 21, the light diffusion may be small. Therefore, as shown in FIG. Resin 2
0, the light emitting diode 14 and the lead wire 15 are covered and configured like a core, and further covered with a flexible synthetic resin 21, and the end of the light diffusing synthetic resin 20 covering the power supply line 11 is bent or the like. Cutting or chipping can be prevented.

As described above, there are various mounting methods for connecting security lights A, A,.
As shown in FIG.
As shown in FIG.
To fix the loop and hook it on the triangular pole 24 or the like, or as shown in FIG.
17, a loop-shaped power supply line is formed and fixed, and a security light A is attached to the loop through a bar 25, or
It is wound spirally, or a loop portion on both sides is inserted into the cylinder with a pole as shown in FIG. 1, or a hook 17 is hooked on the cylinder, and as shown in FIG. In the case of the fence 26, the security light A can be attached by hooking the end of the looped feeder wire into the net 26a and then hooking the hook 17.
In addition, the thing which connected security lights A and A in this way can also be electric decoration.
