The present invention relates to a sealed structure of tunnel lighting fixtures installed at regular intervals on the ceiling or sidewalls of highways or general roads, and in detail, prevents the efficiency of the lighting fixtures due to leakage and soot from the tunnel lighting fixtures to maintain the lighting efficiency. In order to reduce maintenance costs, and to improve durability and safety, the structure of inserting the packing between the main body and the cover improves the structure of the tunnel luminaire to effectively prevent the inflow of foreign substances into the luminaire.

In general, tunnel luminaires not only generate a lot of vortices due to the movement of automobiles, but also corrode well due to various exhaust gases. Particularly, the use of calcium chloride in winter causes severe corrosion of the coupling part of the luminaire. In addition, the environment where the tunnel luminaire is installed is not only humid, but also has a lot of dust and dust, so that when they stick to the inside and outside of the luminaire, the cleaning cycle is shortened, thereby increasing the maintenance cost and causing trouble. The back remains.

In Korean Utility Model Registration No. 20-0313767, a double rubber packing is installed on the edge of the body to increase the sealing effect. However, there is not enough groove formed in the main body, so rubber packing is not easy and there is a problem of slipping out. Rather, rubber packing having a wide width is safe, but conventional rubber packing has a wider width than the edge of the main body. There is a problem that the rubber packing is squeezed sideways by the pressure of the cover by packing high.

The present invention is to solve the above problems, and to improve the hermetic structure of the body and the cover to reduce the maintenance cost of the tunnel luminaires and to aim for durability.

In order to achieve the above object, the present invention, in the closed structure of the tunnel luminaire consisting of a main body is installed, the associated parts such as lamps, ballasts, shielding plate, and the cover coupled to the main body, the frame of the main body According to the present invention, a packing member is included, and the packing member is accommodated in the packing member receiving groove of the main body, and is formed lower than the packing supporting member located at the outer portion of the main body of the main body. The sealing structure of the tunnel luminaire, which abuts inside the packing support member and compresses the packing member is formed along the edge of the corresponding portion of the cover in contact with the packing member. In addition, the main body and the cover are made of aluminum die-cast casting, so that the simplicity of manufacturing, the thermal conductivity, the durability, and the like can be pursued.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, it should be noted that the same elements in the drawings represent the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted so as not to obscure the subject matter of the present invention.

1 is an exploded perspective view showing an embodiment of the present invention. The main body 10 is a place for receiving various devices such as a shielding plate 30, a ballast 51, a lamp 52, a PCB substrate, a reflecting plate, and the cover 20 is coupled to the main body 10 to provide the devices. It protects and serves to illuminate the light of the lamp 52 through the transparent member (53). Since the luminaire is installed on the ceiling or sidewall of the tunnel with the main body 10 located above and the cover 20 located below, the coupling of the main body 10 and the cover 20 is very important. Chlorine ion of calcium chloride (CaCl ₂ ), a snow remover in winter, severely corrodes metals, and sulfur oxides contained in the fumes of automobiles react with moisture in the air to form sulfuric acid droplets and adhere to the packing parts of the body and cover. Proceed faster corrosion of the packing. When sulfur oxide penetrates into the tunnel luminaire, damage of internal parts occurs, which greatly shortens the life of the luminaire. Therefore, the sealing work of the main body and cover should be made thoroughly. In general, such a sealing operation is a packing such as rubber is inserted along the outer periphery of the main body 10 and is pressed into a cover.

FIG. 2 is a detailed view for explaining a coupling relationship between portion A of FIG. 1. A packing member accommodating groove 44 having a sufficient size is formed along the rim of the main body 10 so that the packing member 41 is inserted therein and the outer portion of the groove is called the packing supporting member 42. , The packing supporting member 42 is formed higher than the packing member 41, and the outer circumference of the edge of the corresponding portion of the cover 20 in contact with the packing member 41 abuts inwardly of the packing supporting member 42. The compression protrusion 43 is formed along the edge of the corresponding portion of the cover 20 in contact with the packing member 41 to press the packing member 41. In some cases, it is possible to increase the degree of sealing by forming another compression protrusion. On the other hand, the compression protrusion 43 is slightly different depending on the type of the packing member 41, but is most preferably 1 to 2 mm. In this case, since the compression protrusion 43 is pressed into the packing member 41 by being pressed into the packing member 41, the outer periphery of the cover 20 is also in close contact with the packing member 41 to increase the sealing efficiency. to be.

Conventionally, there is a problem that the packing member 41 is not properly formed to accommodate the packing member 41 or the depth thereof is not deep, and in the present invention, a sufficient packing member accommodation groove 44 is formed. In addition, in the related art, when the packing member 41 is formed higher than the packing supporting member 42 to be compressed by the corresponding portion of the cover 20, the packing member 41 is protruded or distorted. Rather, it was directly exposed to various materials and exposed to corrosion. On the other hand, the use of a non-thick packing member (in the case of O-ring) forms a large number of small grooves and is inserted therein and pressed into the cover, but in the case of tunnel luminaires, the main body 10 and the cover 20 closely adhere to each other. It is believed that sufficient packing member 41 having sufficient deformation force is more efficient because it is closed. In addition, since the main body 10 faces the upper portion, it is preferable that the outer circumference of the rim of the cover is inserted into the inner circumference of the rim of the main body.

The packing member 41 may be inserted into the packing member accommodating groove 44 as it is, but more preferably, it may be firmly fixed by a separate adhesive or attachment means.

On the other hand, it is important to release the heat of the tunnel luminaire sufficiently to protect various related parts in the main body and to prevent the shortening of its life. To this end, in the present invention, the main body and the cover are made of aluminum die casting. When the temperature is based on 20 ℃, aluminum has 14 times better thermal conductivity than stainless steel, and is 2.5 times lighter in specific gravity, so durability and safety are excellent. It is also desirable to coat the body and cover as a whole.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

The present invention improves the packing coupling method between the main body and the cover of the tunnel luminaire, so that moisture or impurities do not penetrate into the tunnel luminaire and short circuit or short circuit does not occur, and corrosion does not occur in related parts inside the product, thereby ensuring a high service life. It works. In addition, the dust is not accumulated in the transparent member there is an effect that the safety is maintained by maintaining the degree of illumination.
