Description

[Technical field]

[0001] The present invention relates to a ground signal with a heating function, and more particularly to a ground signal with a heating function that is installed on the floor of a pedestrian crossing to display a traffic light signal to the outside and dissipates heat upward to melt ice, snow, etc. [Background technology]

[0002] Generally, pedestrian crossings allow pedestrians to cross roads safely, and are primarily found at road intersections and other locations with a large number of pedestrians.

[0003] At such crosswalks, crosswalk signals are usually installed to periodically display stop and crossing signals, and the crosswalk signals are installed at a certain height from the bottom of a pole.

[0004] The above-mentioned crosswalk signals are installed at eye level for pedestrians, but they cannot see the signal unless they look up. Therefore, for example, pedestrians who lower their heads to use their cell phones often fail to quickly recognize the change in the signal. In such cases, pedestrians are often unable to cross the street even though the signal is clear, or they recognize the signal too late and rush to cross, resulting in collisions with vehicles.

[0005] To solve the above problems, in recent years, floor-type pedestrian signal auxiliary devices that are linked to pedestrian crossing signals have been installed underground so that even pedestrians with their heads down can clearly and quickly recognize changes in the traffic light signals. However, because conventional floor-type pedestrian signal auxiliary devices are embedded into the slope of the ground at both ends of the crosswalk, it is difficult for pedestrians waiting for the light to easily identify the floor-type pedestrian signal auxiliary device, and the floor-type pedestrian signal auxiliary device is not able to faithfully perform its original function. Conversely, it is easy for drivers to identify the floor-type pedestrian signal auxiliary device, but there is a problem that the conflicting light of the traffic light the driver is looking at and the floor-type pedestrian signal auxiliary device interfere with safe driving.

[0006] To solve these problems, the standard guidelines for auxiliary devices for floor-type pedestrian traffic signals, which were approved by the National Police Agency in March 2019, state that the direction of the light must be designed to be tilted 10 degrees toward the sidewalk.

[0007] Meanwhile, in winter or in cold regions, when snow accumulates on the ground signal or ice freezes, there is a problem that the light emitted from the ground signal cannot be efficiently emitted to the outside. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Korean Patent No. 10-2210147 [Patent Document 2] Korean Patent Publication No. 10-2023-0021280 Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention has been made to solve the above-mentioned problems, and its object is to provide a ground signal having a heating function that can generate heat to melt the snow or ice accumulated on the top of the ground signal when snow or ice accumulates on the top of the ground signal, thereby allowing the light generated from the ground signal to be efficiently dissipated to the outside. [Means for solving the problem]

[0010] In order to achieve the above-mentioned object, the ground signal device with heating function of the present invention includes a lower housing with an open top; a circuit board arranged inside the lower housing and having a plurality of LEDs mounted on its top surface; an inner lens part arranged on the top of the circuit board; a heating member mounted on the inner lens part; and an outer lens part arranged to enclose the top and sides of the inner lens part and cover the top of the lower housing; and the heating member is heated by an externally approved power source and dissipates heat to the outside of the outer lens part.

[0011] The heating member is made of a hot wire and is electrically connected to the circuit board.

[0012] The heating member is disposed on an upper surface of the inner lens portion.

[0013] A direction-changing protrusion is formed on the side of the inner lens part, and the heating member installed long on the upper surface of the inner lens part has its installation direction changed by the direction-changing protrusion, and is then installed again on the upper surface of the inner lens part in a zigzag shape.

[0014] A seating line groove for seating the heating member is formed on the upper surface of the inner lens portion, and seating protrusions are formed to protrude from both sides of the seating line groove.

[0015] The heating member further includes a pin member that protrudes downward from the lower portion of the inner lens portion, and the tip of the heating member penetrates the inner lens portion and is then connected to the pin member, and the pin member to which the end of the heating member is connected is inserted and connected to a circuit board disposed at the lower portion of the inner lens portion. Effect of the Invention

[0016] The traffic light having a heating function according to the present invention as described above has the following advantages.

[0017] The present invention is equipped with a heating member installed in the inner lens portion, and heat generated from the heating member is dissipated to the outside of the outer lens portion, so that if there is water, ice, snow, etc. on top of the traffic light, it can automatically evaporate or melt it.

[0018] As a result, the light emitted from the LED can be effectively irradiated to the outside even in winter, bad weather, or cold regions, thereby further improving the effectiveness of the ground signal. [Brief description of the drawings]

[0020] As shown in Figures 1 to 6, the ground signal device with a heating function of the present invention includes a lower housing (10), a circuit board (20), an inner lens portion (30), a reflector (40), a heating member (50), an outer lens portion (60), and a fixed rim member (70).

[0021] The lower housing (10) is open at the top.

[0022] The circuit board (20) is disposed inside the lower housing (10) and has a number of LEDs (25) mounted on its upper surface.

[0023] The circuit board 20 is connected to an external power source.

[0024] The inner lens portion (30) is disposed on the upper portion of the circuit board (20).

[0025] A reflector (40) is disposed between the upper part of the circuit board (20) and the inner lens portion (30).

[0026] The reflector (40) reflects the light emitted from the LED (25) so that the light is more strongly irradiated upward.

[0027] The heating member (50) is attached to the inner lens portion (30).

[0028] The heating member (50) will be described later.

[0029] The outer lens portion (60) is disposed so as to enclose the upper and side surfaces of the inner lens portion (30) and covers the upper portion of the lower housing (10).

[0030] The fixed rim member (70) is coupled to the lower housing (10) while covering the periphery of the outer lens portion (60) to prevent the outer lens portion (60) from being separated.

[0031] The heating member (50) is heated by an external power source and dissipates heat to the outside of the outer lens part (60).

[0032] The heating element (50) can be made up of a variety of components.

[0033] As shown in FIGS. 3 to 5, in this embodiment, the heating member (50) is made of a hot wire and is electrically connected to the circuit board (20).

[0034] Therefore, the heating member (50) can be heated by supplying power to the heating member (50) through the circuit board (20) connected to an external power source.

[0035] The heating member (50) made of a heat wire is placed on the upper surface of the inner lens portion (30).

[0036] A number of direction-changing protrusions (33) are formed on the side surface of the inner lens portion (30).

[0037] The heating member (50), which is installed long on the upper surface of the inner lens portion (30), has its installation direction changed 360 degrees by the direction-changing protrusion (33), and is then installed again on the upper surface of the inner lens portion (30) in a zigzag shape.

[0038] The heating member (50) installed on the upper surface of the inner lens portion (30) has a number of heat rays which are redirected by the redirecting protrusions (33) and spaced apart.

[0039] The heating member (50) attached to the upper surface of the inner lens portion (30) transfers heat to the outer lens portion (60) when heated, and the outer lens portion (60) dissipates the heat generated from the heating member (50) upward, thereby heating and melting or evaporating water, snow, ice, etc. present on the upper surface of the outer lens portion (60).

[0040] A long seating line groove (31) for seating the heating member (50) is formed on the upper surface of the inner lens portion (30).

[0041] Further, seating protrusions (32) are formed on both sides of the seating line groove (31).

[0042] The heating member (50) placed on the upper surface of the inner lens portion (30) can be stably placed in the same position where it was originally installed without moving to another place due to the seating line groove (31) and the seating protrusion (32).

[0043] In addition, since the heating member (50) consisting of a hot wire is seated inside the seating line groove (31) and protected by the seating protrusion (32), the heating member (50) is prevented from being cut or damaged by other parts or tools.

[0044] The heating member 50, which is made of a hot wire, is electrically connected to the circuit board 20, and in this embodiment, a pin member 55 is used to make this connection more convenient and accurate.

[0045] The pin member (55) is made of metal and is attached to the lower part of the inner lens portion (30) so as to protrude downward.

[0046] The pin member (55) is made up of two pieces.

[0047] The heating member (50) has two ends which pass through the inner lens portion (30) and are then connected to the two pin members (55).

[0048] The pin members (55) to which the ends of the heating members (50) are connected are inserted into and connected to the circuit board (20) disposed under the inner lens portion (30).

[0049] Therefore, after the pin member (55) and the heating member (50) are first installed in the inner lens portion (30), when the inner lens portion (30) is attached to the lower housing (10), the pin member (55) protruding downward is automatically inserted into the circuit board (20) arranged below and electrically connected thereto.

[0050] As a result, electricity supplied from an external power source is transmitted to the heating member (50) through the circuit board (20) and the pin members (55), enabling the heating member (50) to heat up.

[0051] At this time, the heating member (50) can be operated manually or automatically.

[0052] In order for the heating member (50) to be automatically operated, a sensor is provided.

[0053] The sensors measure temperature, moisture, snowfall, rainfall, etc., and when the values ​​measured by the sensors exceed preset values, the heating member (50) is activated to generate heat.

[0054] As described above, the present invention is provided with a heating member (50) installed in the inner lens portion (30), and the heat generated from the heating member (50) is dissipated to the outside of the outer lens portion (60), so that if there is water, ice, snow, etc. on the ground signal, it can automatically evaporate or melt it.

[0055] As a result, the light emitted from the LEDs 25 can be effectively irradiated to the outside even in winter, in bad weather, or in cold regions, thereby further improving the effectiveness of the traffic light.

[0056] The ground signal device having a heating function according to the present invention is not limited to the above-described embodiment, but may be modified in various ways within the scope of the technical concept of the present invention. [Explanation of symbols]
