BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security light for illuminating and displaying a danger zone along a boundary line in a road construction or a construction site at night or in cloudy weather.

[0002]

2. Description of the Related Art Conventionally, a security light of this type is often connected with a large number of red light bulbs in series at an appropriate distance from each other, and alternately switches a power supply circuit for each of the electric wires to form a red light bulb. Flashing. In this conventional means, a large number of red light bulbs as light emitters are connected in series to electric wires, and the light emitters themselves have a high impedance. Can not be used for In addition, the red light bulb, which is a luminous body, is easily damaged by itself and is exposed to the outside, so care must be taken in handling, and since the service life of the red light bulb is short, the red light bulb must be frequently replaced. In view of the above, a tube-shaped security light in which light emitting diodes are incorporated at appropriate intervals in a transparent flexible tube has recently been used. This tubular security light has 12
Although it can be used for a long time with a V battery and has little damage to the luminous body, it is very convenient for portable use, but there is a drawback in terms of the illuminance of the luminous body. There are drawbacks such as the intensity of body brightness.

[0003]

Therefore, according to the present invention, a light-emitting element such as a light-emitting diode and a reflector for reflecting and diffusing the light source are housed in a tube to promote the brightness of the light-emitting element. It is a main object of the present invention to provide a tubular security light which can emit light in a predetermined wide range with the brightness of the luminous body.

[0004]

According to the security light of the present invention devised to achieve the above object, an electric wire inserted through a flexible tube inside a transparent flexible tube (1). A plurality of light-emitting bodies (3) such as light-emitting diodes are connected to (2) at appropriate intervals, and a plurality of light-emitting bodies (3) having a convex reflecting mirror surface (4a) toward each of the light-emitting bodies (3) are connected. Reflector (4)
Are arranged at appropriate intervals from the light-emitting body (3).

[0005]

The security light constructed as described above is used by hanging it on a fence (8) at a road construction site or the like as shown in FIG. When the illuminator is turned on, the light from the illuminator is reflected and diffused by the reflecting mirror surface (4a) of the reflector (4), and the illuminator
The tube between (3) and the reflector (4) emits light to enhance the effect as a security light that induces the attention of a pedestrian, and the light from each illuminant is reflected by the opposing reflector ( Since the light is reflected and diffused equally by 4), the brightness of each reflector 4 can be kept uniform.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show a typical embodiment of the present invention, in which reference numeral (1) indicates a transparent synthetic resin tube colored red. An electric wire (2) powered by a 12V battery is inserted through the inside of the flexible tube (1). And an appropriate spacing for this wire, for example 400-4
Multiple light emitters with light emitting diodes separated by 30mm
(3) are alternately connected to emit light by energization, and each of the light emitters (3) has a convex reflecting mirror surface (4a) facing the light source of each light emitter (3). A plurality of reflectors (4) are arranged at positions 100 to 130 mm apart from the respective light emitters (3).

In the embodiment shown in FIGS. 1 to 4, the reflector (4) has conical reflecting mirror surfaces (4a) with convex portions directed in the tube axis direction on both left and right sides, and one of the reflecting surfaces is provided. The light source of the luminous body (3) is directed toward the mirror surface (4a). The reflector (4) is provided with a through hole (4b) through which the electric wire (2) is inserted in the shaft core portion. The electric wire (2) is inserted into the through hole (4b), and the position is fixed by a plug (5). The reflector (4) is provided with a guide groove (4c) for fitting the electric wire (2) into the through hole (4a). In this way, the wire (2) with the light-emitting bodies (3) and the reflectors (4) attached alternately is inserted into the flexible tube (1), and both ends are fixed to the tube end. Thereby, a security light can be easily formed. In addition, as shown in FIG. 2, when the flexible tube (1) is inserted into the flexible tube (1), a large play is prevented from occurring between the outer peripheral surface of the reflector (4) and the inner surface of the flexible tube (1). Preferably, this allows the reflector to be used during use.
(4) and the luminous body (3) can be prevented from rattling in the flexible tube (1). In the figure, (9) and (10) show a female connector and a male connector for power connection.

A plurality of luminous bodies (3) connected to the electric wire (2)
Are formed so as to alternately flash every other. When the illuminator (3) is turned on, light from the illuminator is reflected and diffused by the reflecting mirror surface (4a) of the reflector (4), and the illuminator (3) and the reflector (4)
A portion between the two emits light, and the effect as a security light can be enhanced. The light emitting diode constituting the light emitting body (3) is preferably a standard type of 2.4 to 2.5 V which is generally commercially available.

FIGS. 5 to 7 show another embodiment.
5 and 6 show an embodiment in which the reflector (4) according to the present invention is slightly modified, and a fitting hole (4d) extending in the axial direction is formed on the opposite surface of the reflector (4a). Is provided, and the enlarged end portion (6b) of the branch line (6a) branched from the reflector holding line (6) inserted through the flexible tube (1) along the electric wire (2) is fitted. The fitting of the reflector (4) is performed by fitting into the hole (4d). At this time, the tip of the branch line (6a)
b) To prevent b) from falling out of the fitting hole (4d)
(7) is preferably pushed into the opening of the fitting hole (4d).
It is preferable that a groove (4e) for guiding the branch line (6a) is formed from the fitting hole (4d) toward the outer peripheral surface of the reflector (4). In this embodiment, each reflector (4) is arranged on both sides of each light emitter (3), and is arranged at a position spaced from the light emitter by 50 to 80 mm. Thus, the luminous body as in this embodiment
When the reflector (4) is distributed on both sides of (3), the luminous body (3)
Is suitable for those having multidirectional light emission without directivity.

The flexible tube shown in FIGS. 6 and 7

As a means for easily inserting (2) into the flexible tube (1), a part of the peripheral surface of the flexible tube (1) is divided along the axial direction, and The protruding portions (11a) and (11b), which are shaped like
2) to form an engaging projection (1a) and an engaging recess (1b) detachably engaged with each other on the outer end surface thereof, and accommodate the electric wire (2) in the space (12), Reflector (4) and luminous body (3)
After being stored in the flexible tube (1), the engaging uneven portion (1a)
(1b) is engaged.

In both of the above embodiments, the flexible tube
The diameter and length of (1) and the numbers and intervals of the light-emitting bodies (3) and the reflectors (4) can be arbitrarily selected and designed. Also, reflector (4)
