The present invention relates to a case of a lighting lamp used as a night light of a road, a tunnel, a plant, a construction site, a campsite, and more specifically, by installing an airtight packing having excellent elastic restoring force on the body and the cover, respectively. When the cover is closed to the main body, the two airtight packings are in close contact with each other, thereby double sealing by mutual restoring force, thereby preventing foreign matters and maintaining moistureproof and waterproofing more efficiently with high sealing force. For example, the present invention relates to a sealing device for a lamp case which is effectively used for a soot, fine dust and a humid tunnel.

In general, luminaires for irradiating the lamp light toward the front by a reflector are widely known.

In the above-mentioned general lighting fixture, the light emitted from the lamp illuminates a specific area of the roadway, sidewalk or work site, so that safety walking, driving and construction work can be easily performed. Due to its characteristics, it is installed and used at a high position from the ground.

However, the above-mentioned lighting fixtures are installed outdoors and are always exposed to rainfall, so it is necessary to consider the waterproofness of the inside of the main body.

In particular, in tunnel lighting, which is installed in a tunnel with a lot of smoke and dust and moisture of a car, it is installed to reduce the deterioration of traffic function in a narrow space unlike a road. Black hole phenomenon occurs when entering, that is, the moment when the vehicle enters the dark tunnel while the driver of the vehicle is adapted to the bright brightness outside the tunnel, and the black hole phenomenon occurs immediately after the vehicle enters the tunnel. Due to physiology, dark acclimation (어지는: light to dark acclimatization) occurs that slows eye adaptation.

This dark adaptation phenomenon causes temporary blindness for the driver and is a major cause of traffic accidents. Accordingly, it is necessary to install the lighting inside the tunnel so that the driver's vision does not suddenly decrease with respect to the dark adaptation phenomenon.

Conventional tunnel lighting fixtures installed inside the tunnel to prevent such dark adaptation is fixed to the main body made of synthetic resin material in the width direction or the longitudinal direction at regular intervals on the back of the main body and the main body Two brackets to fix the inner wall of the tunnel, a cover having a transparent glass on the front surface coupled to open and close to the main body, a lamp installed in the main body to emit light through the transparent glass of the cover, and It is composed of a reflecting plate provided in the main body to reflect the light of the lamp, and a rubber packing ring interposed between the main body and the cover to maintain airtightness.

However, since the general lighting fixtures or tunnel lighting fixtures as described above are mostly sealed by one rubber packing ring, when used for a long time, the elasticity and adhesiveness of the rubber packing ring decreases, and a gap is generated between the close contact surfaces. By soot, fine dust and moisture in the tunnel are introduced into the tunnel luminaire, it adheres to the reflector, lamp, and transparent glass, so that the lighting becomes dark and the metal parts such as the reflector and lamp socket are corroded. There was a problem of shortening the life.

Therefore, in recent years, double rubber packing rings are installed in casings such as tunnels installed on the ceiling or side walls of soot and fine dust tunnels to prevent the inflow of foreign substances such as smoke and dust and contaminants. As a method for preventing the corrosion of the lamp and the reflector according to use, it is known, for example, by Korean Utility Model Registration No. 225336 (name: double sealed structure of tunnel lamp case).

According to the Utility Model Registration No. 225336, a tunnel having insertion recesses alternately formed around the outer end of the bottom of the body and the inner end of the lower cover, and a sealing rubber packing ring inserted into the insertion recesses, respectively. The double sealing structure of the case is provided.

The double sealing structure of the case such as a tunnel is coupled to the cutting groove of the lower cover by fastening the clip fixed to the body to the incision groove of the lower cover, so that the sealing rubber packing ring indented into the insertion recess of the body and the lower cover is fixed in close contact with each other to prevent the release to the outside. When the body and the lower cover are in contact with each other, a constant pressure is evenly applied to the sealing rubber packing ring to double seal the case such as the tunnel.

However, the double sealing structure of the case, such as the tunnel is a method in which the two rubber packing ring having elastic force is in close contact with each other by the restoring force of each other, but in close contact with the contact surface of the body and the lower cover by the pressing force of the body and the lower cover. Therefore, the long term use of the case, such as tunnels, causes the elasticity and adhesion of each rubber packing ring to gradually deteriorate, resulting in the two contact surfaces of the rubber packing ring, that is, the rubber packing ring and the contact surface of the body and the rubber packing ring. A gap is generated between the contact surface and the lower cover, so that it is difficult to guarantee a perfect seal, thereby causing the soot, fine dust and moisture in the tunnel to be introduced into the case such as the tunnel.

Therefore, the object of the present invention is to prevent moisture and moisture from the outside with high sealing force and more effectively block the inflow of smoke and fine dust from the outside to prevent corrosion and degradation of the lamp and reflector due to long-term use of the lamp. It is to provide a sealing device of the lighting lamp case which can be installed, each of the airtight packing is installed on the rim of the body and the rim of the cover, each having a different airtight packing with excellent elastic resilience, when the cover is closed to the body This is achieved by allowing the two hermetic packings to have a double sealing action with each other's elastic restoring force in close contact with each other.

It is another object of the present invention to provide a sealing device for a lighting lamp case that is simple in structure and easy to disassemble and assemble, and the sealing device has a key groove having one side opened to face each other to the edge of the main body and the cover. Forming and elastically fitting the different hermetic packings to the keyways or disengaging therefrom.

Further objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

According to the sealing device of the lamp case according to the present invention for achieving the above objects, the foreign matter into the body by elastically sandwiching the different airtight packings respectively in the first and second key grooves formed on the edge surface of the cover and the body.

The other hermetic packing includes: (1) a second tube body having a rivet cross section as a whole, and having a second hollow portion to impart elastic restoring force therein; (2) a pair of protruding outwards along the longitudinal direction on both sides of the upper part of the second tube body to be in close contact with the rim surface of the main body when the lower part of the second tube body is fitted into the second key groove of the main body; A second locking protrusion; (3) a curved portion having a constant thickness and convexly connected to the pair of second locking protrusions to be in close contact with the pressing surface of the first tube body; And (4) protruding perpendicularly to the center of the second hollow portion at a predetermined distance from the curved portion, and pushing the curved portion upward with respect to the pressing surface of the first tube body when the cover is closed with respect to the main body. It includes a blotting protrusion for sealing.

Optionally, the inner surface of the pressing surface is characterized by consisting of a concave curved surface.

Optionally, the interval between the inner surface of the curved portion and the blotting protrusion is 1.5 mm.

As such, when the cover is closed with respect to the main body in a state in which different airtight packings having excellent elastic restoring force are installed on the rim of the main body and the rim of the cover, respectively, the pressing surface of the first tube body and the second tube body. The curved portions of the first and second hollow portions have an elastic restoring force with each other, and are primarily brought into close contact with each other, and the crushing protrusions formed on the second tube body secondary the pressing surface of the first tube body through the curved portions. It can be seen that by pressing the high double sealing effect is achieved.

As a result, different airtight packings with excellent elastic resilience prevent moisture, water resistance, and the inflow of smoke and fine dust from the outside more effectively, preventing corrosion and deterioration of lamps and reflectors due to long-term use of lighting. There is an advantage that can be prevented, and more quickly joining, detaching or replacing different hermetic packing.
