Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a bridge illumination device using an FDL fluorescent lamp as a light source.

[0002]

2. Description of the Related Art When illuminating a bridge mainly at night, a wire is suspended from the bridge along the position of the illumination, and an illumination device is attached to the wire. Conventionally, the light source used for this purpose has been a small fluorescent lamp, such as a small incandescent light bulb or a small light bulb.

However, conventional illumination devices have poor visibility from a distance because the light intensity of the light source is small. In the case of a long bridge, it is inevitably visible from a distance, so conventional light sources are not enough.

Accordingly, the present inventor has conceived of using a relatively small FDL fluorescent lamp having a large total luminous flux.

The FDL fluorescent lamp is a compact fluorescent lamp in which four straight tube portions are bundled so as to be positioned at each corner of a regular square, and a bent arc tube is formed as a whole. . Although this fluorescent lamp is compact, it has a large total luminous flux and is capable of producing white light, so it is used in various lighting equipment. It is devised from. For example, Japanese Utility Model Laid-Open Publication No. 3-127713 discloses that when an FDL fluorescent lamp is mounted on a downlight in a horizontal direction, the four arc tubes of the FDL fluorescent lamp are arranged so that the diagonal directions are horizontal and vertical. Thus, there is described a lighting apparatus that effectively uses light from four arc tubes.

[0006]

SUMMARY OF THE INVENTION The above prior art is based on FD.
Attention is focused exclusively on combining L fluorescent lamps with reflectors.

However, the illumination device does not illuminate the surroundings like a lighting device, but uses a convex lens to condense the light of the light source in a specific direction so that the light can be easily viewed from a distance. Therefore, the conventional technology of the lighting fixture cannot be used.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a bridge illumination device in which the amount of condensed light is increased by specifying an optimal direction for condensing light by combining an FDL fluorescent lamp with a convex lens.

[0009]

According to the present invention, there is provided a bridge illumination device comprising: a box-shaped device main body; and a plurality of FDL-type fluorescent lamps protruding substantially perpendicularly from a front surface of the device main body and mounted on the device main body. A lamp; and a globe provided with a convex lens portion surrounding each FDL-type fluorescent lamp and attached to the apparatus body so as to be able to see three straight tubes of the arc tube of the FDL-type fluorescent lamp; And a wire attachment device for projecting from both sides of the instrument body so that the wire is located behind the instrument body and attaching the instrument body to the wire.

The FDL fluorescent lamp is arranged so that four straight tube portions are located at each corner of a regular square, and the discharge tube is bent so as to form one discharge path.
One discharge pipe is formed by connecting two straight pipes with a connecting pipe. The FDL fluorescent lamp is mounted on the fixture body via a socket, and the socket is provided on the front face of the fixture body. The FDL fluorescent lamp is arranged so that three straight pipes can be seen from the convex lens part of the globe.

The plurality of FDL fluorescent lamps may have the same color or different emission colors. In order to make the emission colors different, the phosphors may be of the respective emission colors, a color filter film may be formed on a fluorescent lamp emitting white light, or a cylindrical color filter body may be attached. If necessary, any two or more of the above may be used in combination.

According to a second aspect of the present invention, in the illumination device for a bridge according to the first aspect, the plurality of FDL fluorescent lamps are linearly arranged along the length direction of the wire. It is characterized by having.

In the present invention, since the FDL fluorescent lamps are arranged along the length direction of the wire, all the FDL fluorescent lamps can be viewed well from the general viewing direction of the bridge. Also, the number of FDL fluorescent lamps can be selected according to the intended illumination effect.

According to a third aspect of the present invention, in the illumination device for a bridge according to the first or second aspect, the plurality of FDL fluorescent lamps are divided into red, green and blue light emission; Is characterized in that a ballast for each FDL fluorescent lamp and a flicker control device for the FDL fluorescent lamp are housed.

In the present invention, since the blinking control device is built in the apparatus main body, the illumination effect can be emphasized by switching the fluorescent lamp of each color for each luminescent color or remotely switching each luminescent color simultaneously. .

According to a fourth aspect of the present invention, there is provided the illumination device for a bridge according to any one of the first to third aspects, wherein the wire mounting device has an intermediate portion fixed to a side surface of the device body. One end has a first arm extending forward from the glove, and the other end has a second arm extending rearward of the instrument body, and further projects outward from tips of the first and second arms. It is characterized by forming a wire attachment part.

According to the present invention, the structure of the wire attachment device is simple, and the illumination device can be easily attached between the two wires.

According to a fifth aspect of the present invention, there is provided the illumination device for a bridge according to the fourth aspect, wherein the front plate and the glove of the device main body can be divided into two along the wire.

In the present invention, since the front plate of the glove and the instrument main body can be divided into two parts, the instrument main body is not detached from the wire when replacing the FDL fluorescent lamp and inspecting or exchanging parts housed in the instrument main body. You may.

The instrument body only needs to be able to divide the front plate at least into two parts. If necessary, by forming one side plate integrally with the front plate, the workability in the instrument body can be further improved. .
