The present invention relates to a tunnel lamp using a fluorescent discharge lamp, and more particularly, to an improvement of a lamp installed in a tunnel or an underground roadway provided in a highway, a national road, and a city road.

In the case of highways and national roads, tunnels are formed in the rough mountainous terrain for straightening of the route, and in the case of downtown roads, underground is created by undergrounding the intersections of railways, highways, and boulevards without signal traffic. It is a driveway.

Since the tunnels and underground roads (hereinafter referred to as tunnels) are large in length, they do not have natural light and thus remain in a dark state, which causes considerable difficulty in driving a car. There is a problem such as leading up to.

In order to solve this problem, lights are installed on both sides of the upper part of the tunnel to brighten the inside of the tunnel, and these lamps brighten the entrance of the tunnel to prevent sudden darkening when entering the tunnel. It is installed to be able to adapt to the bright outside in a dark state as close to the exit.

Conventional lighting is installed in the tunnel as described above will be used a lot of sodium and fluorescent lamps mainly depending on the lighting method.

Since sodium lamps (or metal halide lamps) emit light when the consumable arc tube is burned, the life span ends when the arc tube is exhausted. The more often the lights are off, the shorter the lifespan will be.

In the fluorescent lamp (Hot Cathod Lamp), the electrode is filament-shaped, the filament is hot and the hot electrons come out, so the electrode of the fluorescent lamp is in a state of receiving heat continuously.

In addition, since the filament is repeatedly contracted and expanded due to the heat shrink expansion coefficient of the filament, the filament is cut off as time passes and the life of the fluorescent lamp is over.

As described above, sodium lamps or fluorescent lamps, which are commonly used as tunnel lighting lamps, often cause poor lighting due to ambient temperature and humidity, and may cause unlit lighting, resulting in frequent repairs. And inconveniences that must be followed by maintenance and replacement work.

When replacing the lamps at the end of life as described above, because the lamps are located at a considerable height, the elevator can be installed in the storage box of the freight car or a dedicated device is installed on the ground.

When replacing the tunnel lighting, it is necessary to block some lanes in the direction of the replacement, so that the operation is carried out with the vehicle control personnel in the early morning when the traffic volume is small. There are several problems, such as being exposed to a significantly higher risk of safety accidents due to speeding and drowsy driving.

Therefore, in the present invention to solve the problems described above, by using a cold fluorescent lamp (Cold Cathode Lamp) type discharge fluorescent lamp that does not generate heat to the electrode to configure the tunnel lighting lamp to ensure sufficient illumination inside the tunnel The main purpose is to brighten the vehicle for safe operation, reduce the cost of maintenance due to its semi-permanent life, and increase the convenience of tunnel holders and operators using the tunnel.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention for achieving the above object.

Tunnel lamp 30 to which the technology of the present invention is applied is configured to use tunnel lamps using a cold cathode lamp (Cold Cathode Lamp) type discharge fluorescent lamp to achieve a bright light while extending the life and the number of maintenance work In other words, it can contribute to cost reduction.

Tunnel lamp 30 of the present invention for this purpose, the receiving groove 31 is formed in a substantially rectangular box type having a lamp housing 32, for supplying power to the inner center of the lamp housing 32 Secure the transformer (33).

The transformer 33 has a built-in timer for setting the time of 24 hours to distinguish between day and night, it is preferable to change the voltage applied to the electrode according to the situation of day and night to automatically adjust the illuminance.

The sockets 37 formed on the ceramic sockets 35 and 36 are fixed to both sides of the lamp housing 32 by fixing the ceramic sockets 35 and 36 connected by a transformer 33 and a wire (wire) 34. The cup type copper contact 38 is provided.

The transformer 33 and the ceramic sockets 35 and 36 are fixed using the lamp housing 32 and conventional fixing means such as bolts or screws.

Above the transformer 33 and the ceramic sockets 35 and 36, a reflector 39 is formed to reflect light emitted from the lamp to increase illumination, and the reflector 39 efficiently reflects the lamp light. The reflective surface 40 of the concave-convex or semi-circular shape may be provided as many as the number of lamps so as to reflect.

The bent end 41 for fixing the lamp housing 32 to the lamp housing 32 is formed at both ends of the reflection shade 39 in the width direction, and the electrodes of the lamp are provided at the ceramic sockets 35 and 36 at both sides of the reflection surface 40 in the longitudinal direction. The lamphole 42 is formed to be combined.

The lamp hole 42 further includes an airtight packing 43 to hold the electrode portion of the lamp in a stable state without impact and to prevent the inflow of moisture or foreign substances into the lamp hole 42.

The lamp 45 inserted into the lamp hole 42 of the reflector 39 and coupled to the ceramic sockets 35 and 36 is provided with a long length and has a lamp tube in which neon or argon gas is mixed and injected therein. The electrode part 47 which protrudes by changing a direction in a 90 degree direction from the both ends of 46 is provided.

The lower end of the electrode portion 47 is provided with a cylindrical brass contact (48) to be coupled to the copper contact 38 of the ceramic socket (35, 36), the inside of the upper by the high voltage supplied A bell type electrode 49 emitting high voltage electrons is incorporated.

One side of the cover 51 having the tempered glass 50 is coupled to the upper side of the lamp 45 by a hinge so as to be opened and closed, and the cover 51 and the lamp housing 32 opposite to the hinge are hooked. It is configured so that it can be interrupted by conventional locking means such as hooks.

The present invention as described above,

After the transformer 33, the ceramic sockets 35 and 36, the reflector 39 and the lamp 45 are assembled in the lamp housing 32, the lamp 51 is completed by the cover 51 and installed in the tunnel. do.

The installed lamp 30 is a power supply supplied to the transformer 33 is applied to the copper contact 38 of the ceramic sockets 35 and 36 through the wire 34, the lamp 45 coupled with the copper contact 38 The final power is applied to the vertical electrode 49 through the brass point 48 of).

Then, the high pressure is conducted from the electrode 49 to emit high voltage electrons, and the light is generated by colliding with the fluorescent material colored on the inner wall of the lamp tube 46 by neon or argon gas injected into the lamp tube 46 to emit light. will be.

In particular, in the case of the present invention, the voltage of 220 volts is applied to the electrode 49 during the day and 140 volts is applied to the electrode 49 during the day by setting the timer provided in the transformer 33. Adjustments are made automatically, eliminating the need for separate power management.

Since the lamp 45 of the present invention does not generate heat at the electrode 49, it can theoretically maintain a semi-permanent lifespan, so that replacement work according to lamp life is unnecessary even in long-term use, thereby reducing the cost of replacement. Of course, the risk of a safety accident can be excluded.

The present invention as described above is maintained by a long life while using a cold cathode lamp (Cold Cathode Lamp) type discharge fluorescent lamp that does not generate heat to the tunnel to help safe operation with sufficient illumination to ensure safe operation It is an invention that has various effects, such as reducing the cost of repairs and eliminating the concern of safety accidents without frequent replacement.
