Description

Floor traffic light module with improved construction convenience {GROUND SIGNAL LIGHT MODULE WHICH CAN BE CONSTRUCTED EASILY}

The present invention relates to a method of constructing a floor traffic light module and a floor traffic light with improved construction convenience.

Recently, as the use of smartphones increases, traffic accidents caused by Smombie (Smart-phone + Zombie = Smombie), who do not look at the surrounding environment by lowering their head and focusing on the smartphone screen, are also increasing.

Accordingly, in order to prevent such traffic accidents of smombies, a technology capable of recognizing the current crosswalk signal without raising a head is being developed by installing a floor traffic light on the entrance of a crosswalk.

Such a floor traffic light is configured to install the LED inside a transparent or semi-transparent case, and to emit red or green light from the LED to indicate the current pedestrian signal of the crosswalk.

Usually, such a floor traffic light is installed in front of a crosswalk, and the process of removing the sidewalk block in order to bury the floor traffic light in the ground must be preceded, and the floor traffic light must be reclaimed by aligning it in a line in the width direction of the crosswalk.

If multiple floor traffic lights are installed side by side in the width direction of a crosswalk, you must fix one floor traffic light on the ground, place neighboring floor traffic lights side by side, and check that each floor traffic light is positioned on a straight line. . This process is repeated to install a plurality of floor traffic lights side by side in the width direction of the crosswalk.A lot of effort and time are required for the construction of the floor traffic lights, and even if a lot of effort and time are invested, the floor traffic lights are in line. There is a problem that cannot be guaranteed to be aligned with.

In addition, when any one of a plurality of floor traffic lights buried adjacent to each other is broken or repair or replacement is required, the above-described process must be repeated again, and a simple construction method is required.

Meanwhile, electronic components including LEDs are installed inside the floor traffic lights, and various places are waterproofed in case rainwater flows in.

In addition, if necessary, by constructing a drainage channel at the location where the floor traffic lights are buried, or by separately installing a sidewalk block with excellent permeability around the permeable sidewalk block, and by constructing a drainage channel around such a permeable sidewalk block, rainwater can be prevented from falling into the floor signal light. It also prevents it from entering.

However, even if various places are waterproofed or a drainage channel or a permeable sidewalk block is separately constructed in case of rain, there is always the possibility of failure due to rainwater from the landfill area such as floor traffic lights, and the construction is complicated. Exists.

The matters described as the background art are only for enhancing an understanding of the background of the present invention, and should not be taken as acknowledging that they correspond to the prior art already known to those of ordinary skill in the art.

In order to install the LED 50 through the guide hole 24, the height of the coupling protrusion 12 must be formed to be smaller than the depth of the guide hole 24. That is, as the LED 50 approaches the end of the coupling protrusion 12, the illumination of light emitted to the outside through the upper cover 10 is improved, so that the LED 50 is maximally coupled through the guide hole 24. It is preferable to install it close to the protrusion 12, and for this purpose, a space for installing the LED 50 must be provided inside the guide hole 24.

In this way, light transmission efficiency is maximized due to the configuration of the convex shape of the end of the coupling protrusion 12, the lens L formed on the surface of the upper cover 10, and the reflective coating layer C on the inner circumferential surface of the guide hole 24, thereby maximizing the light transmission efficiency. Visibility is improved.

The guide hole 24 may be formed by being divided into a lower section 24a, a guide section 24b, and an upper section 24c.

The lower section 24a is for preventing the mounted LED 50 from being separated from the guide hole, the guide section 24b is for efficiently guiding the light irradiated from the LED 50, and the upper section 24c ) Is to efficiently expand and irradiate the transmitted light to pedestrians.

The dehumidifying member 30 is configured to remove moisture generated inside the floor traffic light G, and may be made of various materials such as silica gel.

According to the present invention, a heat dissipation unit 40 is installed on the bottom of the substrate P to dissipate heat generated from a floor signal lamp. The heat dissipation unit 40 is configured to be installed at the lowest part of a traffic light on the floor, and is installed so as to face the base plate 72 of the base rail 70.

The heat dissipation unit 40 may include a first heat dissipation plate 42 and a first heat dissipation fin 42a.

The first heat dissipation plate 42 is bonded to the bottom surface of the substrate P and is made of a material having excellent thermal conductivity and heat dissipation performance such as aluminum and copper, and a plurality of the first heat dissipating plate 42 is provided on the bottom surface of the base plate 72 in the direction of the base plate 72. Four first heat dissipation fins 42a may be protruded.

It is preferable that the first heat dissipation fin 42a be installed at a position corresponding to the position where the LED 50 is mounted in consideration of heat dissipation efficiency.

In order to solve this problem, a watertight member 60 that is advantageous for shock absorption and excellent in corrosion resistance may be embedded in the space formed between the first heat dissipating plate 42 and the second heat dissipating plate 44.

In the present invention, the watertight member 60 may be provided in a multilayer structure, and more specifically, it is provided in a solid first watertight layer 62 adjacent to the base plate 72, and a curable gel or sol. It may be made of one or more second watertight layers 64 stacked on top of the first watertight layer 62.

The floor traffic light G may generate a crack R between the inner wall of the guide cover 20 and the first watertight layer 62 due to an impact transmitted from the ground as the usage period elapses. 20) When a crack (R) or the like occurs between the inner wall and the first watertight layer 62, the second watertight layer in the form of a gel or sol, which was sealed by the guide cover 20 and the first watertight layer 62 ( 64) is discharged through the cracks (R) and hardened while in contact with the atmosphere to improve watertightness.

More preferably, the second watertight layer 64 of the present invention may be provided with a plurality of layers, and it is preferable to use a resin having a slower curing speed as it goes upward.

Accordingly, when a defect occurs in the first watertight layer 62, the second watertight layer 64 stacked thereon is cured to compensate for the defect, and then a defect occurs in the cured second watertight layer 64. If the second watertight layer 64 disposed thereon is cured, the defects are compensated, so that the watertightness can be improved drastically and the lifespan can be extended.

In addition, the watertight member 60 may further include one or more boundary films F having a plurality of flow holes H disposed between each layer.

The boundary film (F) improves productivity by facilitating manufacturing by making the boundary between layers smoothly formed when the second watertight layer 64 is filled, and the first watertight layer 62 or the second watertight layer ( When a defect occurs in 64), the second watertight layer 64 in the form of a gel or sol is gradually discharged to the crack R through the flow hole H, thereby securing a time for curing by filling the defect area.

It can also perform the function of the hole (H).

It is preferable that a predetermined space is formed between the bottom of the second heat dissipation plate 44 and the guide plate 72 so that the incoming rainwater flows through the bottom traffic light G. For this purpose, the outermost part of the upper cover 10 It is preferable to form a pair of coupling protrusions 12 positioned on the side to protrude further toward the base plate 72 than the bottom surface of the second heat dissipation plate 44.

Accordingly, a predetermined flow path is formed between the second heat dissipating plate 44 and the base plate 72, and rainwater absorbed into the ground flows through the flow path when it rains, so that heat can be radiated by water cooling. Of course, it is also possible to artificially adopt a water-cooled heat dissipation type by supplying fluid to the flow path as necessary. It is preferable that a drain hole 10b is formed at the lower end of the upper cover 10 so that rainwater and fluid can flow.

Meanwhile, as for the floor traffic light G, the substrate P may be formed to be inclined upward from the sidewalk toward the roadway so as to prevent the light irradiated from the LED 50 from obstructing the driver's view.

It is preferable that the inclined angle of inclination of the substrate P is formed to be 5 to 15° based on the ground. If the inclination angle is less than 5°, the effect of improving the visibility of pedestrians and reducing the fatigue of the vehicle driver is insignificant, and if it exceeds 15°, there is a problem that it becomes difficult for pedestrians adjacent to the floor traffic lights to recognize the signal.
