More particularly, the present invention relates to a locking device for a tunnel luminaire for preventing falling and dropping, and more particularly, to a locking device for a tunnel luminaire, which comprises a body and a cover, To a locking device for a tunnel luminaire for preventing fall-off of the cover by preventing the lock ring from coming off, and preventing traffic accident in the tunnel due to falling or dropping of the lock ring.

Generally, the inside of a tunnel is provided with a lighting lamp for the safety of a vehicle or a pedestrian passing through the tunnel. An apparatus installed on the inner wall of the tunnel for installing such a lighting lamp is called a tunnel lamp. At this time, LEDs having long lifetime and low power consumption are mainly used as illumination lamps for tunnels.

Meanwhile, Korea Highway Corporation has a lock ring and a hinge for easy opening and closing for the maintenance of the LED lighting fixture used in tunnels and the like, and the lock ring and the hinge are not welded. This is because in the case of welding, the lock rings or hinges may fall due to corrosion on the welds.

And the lighting lamp installed in the tunnel is always exposed to foreign matter such as soot emitted from the vehicle or dust in the air, so that it is easily dirty and is exposed to moisture caused by water sprayed when the water is cleaned or the air in the tunnel is cleaned. Therefore, the tunnel luminaire in which the tunnel light is installed is made of aluminum or stainless steel which is not easily damaged by rusting even when exposed to moisture or moisture.

When the tunnel luminaire is made of aluminum, it is easily corroded by the calcium chloride sprayed on the road for safe driving on snowy roads and ice roads in winter. Of course, the surface of aluminum is painted to prevent corrosion, but depending on the installation location of the tunnel luminaire, the corrosion is severe and the coating of the tunnel luminaire is peeled off and partly corroded. If the tunnel luminaire is corroded like this, it loses its dustproof and waterproof function, and the hinge or the lock ring is dropped and falls, thereby increasing the risk of car accidents and fire.

Accordingly, recently, stainless steel is mainly used as a material for a tunnel luminaire than aluminum. The tunnel luminaire made of stainless steel is not easily corroded due to its excellent corrosion resistance, and has high strength and high durability. Also, the locking ring for fixing the cover of the tunnel lighting fixture is also made of stainless steel, and an embossed portion is formed at a position where the hinge is provided for positioning the hinge.

However, one or two locking rings provided in the conventional tunnel luminaire are not provided with separate structures for preventing fall-off and fall-off, but are fixed only to the body through the embossing structure, There is a problem that traffic accident in the tunnel is caused by falling off parts constituting the lock ring from the vehicle.

Meanwhile, as a result of investigation of the prior art related to the present invention, a large number of patent documents have been searched and some of them will be described as follows.
