Abstract

PROBLEM TO BE SOLVED: To provide a protective lighting fixture that does not cause an electric leak and any other obstacles even when it is used on a rainy day for being excellent in waterproofness and can be simply fitted to a barricade stand and removed therefrom. SOLUTION: A plurality of security lamps 3 electrically connected to an electric wire 2 at certain intervals are inserted into a lengthy transparent pipe 1 including sufficient strength as a connecting pipe for a barricade stand 4. Both ends of the transparent pipe 1 are provided with a freely detachable blocking means 5. The end of the electric wire 2 can be provided with an electrical connection means 8.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a construction site,
The present invention relates to a security lighting device used for ensuring safety at a road construction site or the like.

[0002]

2. Description of the Related Art Conventionally, this kind of security lighting equipment has a wire 2
A plurality of security lights 3 are electrically connected at regular intervals, and as shown in FIG. 3, a steel pipe as a connecting pipe of a barricade stand 4 installed at a building construction site, a road construction site, or the like. 11, it was attached to the barricade stand 4. As the security light 3, an incandescent bulb, a flashing incandescent bulb, or the like has been used.

[0003]

However, the above-mentioned conventional security lighting device is inferior in waterproofness even when an incandescent bulb or an automatic flashing incandescent bulb is used as the security lamp 3 because it is exposed. Therefore, when used in rainy weather, there is a problem that an electric leakage and other obstacles occur.

In addition, when the conventional security lighting device is mounted on the barricade stand 4, it is troublesome to route the electric wire 2 to the steel pipe 11 of the barricade stand 4, and it takes time to mount and remove. Had issues.

Accordingly, the present invention provides excellent waterproofness even when used in rainy weather, without causing electric leakage and other obstacles, and without troublesome work such as routing of the electric wire 2. The purpose is to provide a security lighting device that can be easily attached to and detached from the barricade stand 4.

[0006]

Therefore, the security lighting device of the present invention includes a wire 2 in a long translucent pipe 1 having sufficient strength as a connecting pipe for a barricade stand 4. A plurality of security lights 3 electrically connected are inserted at regular intervals.

In the security lighting device of the present invention, detachable sealing means 5 is provided at both ends of the light-transmitting pipe 1.

Further, an electric connection means 8 may be provided at an end of the electric wire 2 in the security lighting device of the present invention.

[0009]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a security lighting device according to an embodiment of the present invention.

In the security lighting device of the present invention, a plurality of security lamps 3 electrically connected to the electric wires 2 at predetermined intervals are inserted into a long translucent pipe 1.

The light-transmitting pipe 1 is made of a high-strength synthetic resin such as polycarbonate, for example, and has sufficient strength as a connecting pipe for the barricade stand 4 as shown in FIG. . At both ends of the light-transmitting pipe 1, sealing means 5 such as a detachable cap is provided. The inside of the light-transmitting pipe 1 is waterproofed by the sealing means 5, so that the security lighting device of the present invention does not cause a short circuit or other trouble even when used in rainy weather.

Further, the translucent pipe 1 is generally used as a connecting pipe for a barricade stand 4.
A pipe diameter of 8.6 mm is preferable because it can be easily attached to the barricade stand 4 using the clamp 6 of the connection pipe.

The security light 3 may be an incandescent light, a flashing incandescent light, or a light emitting diode (LED). For example, in the case of an LED, a plurality of electric wires are electrically connected in parallel to the electric wire 2 at regular intervals, and a battery, an AC power supply, etc. And the security light 3 is turned on or off. Further, an electrical connection means 8 such as an outlet and a plug may be provided at one end or both ends of the electric wire 2. By using the electric connection means 8, if the security lighting device of the present invention is used as a connecting pipe of the barricade stand 4, the security lighting device is not limited to two as shown in FIG. Therefore, it is possible to illuminate an appropriate place such as a construction site or a road site in an appropriate range.

[0014]

As described above, the security lighting device of the present invention has excellent waterproofness because it is constructed as described above. Even when the lighting device is used in rainy weather, electric leakage and other troubles occur. It can be easily attached to and detached from the barricade stand 4 without any troublesome work such as routing of the electric wire 2.
