Description

{Floor lighting apparatus for walking direction at crosswalk}

The present invention relates to a floor lighting device for indicating pedestrian crossing, and more specifically, to a floor lighting device for indicating pedestrian crossing, which can drastically reduce power consumption by allowing the use of a smaller number of LEDs compared to the width of a crosswalk, and minimizes manpower, time, and costs required for construction work, maintenance, and management work, by eliminating the need for burying, etc.

In general, crosswalk floor-type pedestrian signal lights are LED lights installed on the floor at the boundary between the crosswalk and the sidewalk to ensure the safety of pedestrians and vehicles. The LED lights are embedded so that the light-emitting surface of the LED is visible to the outside, and are controlled to work in conjunction with the crosswalk signal lights.

This type of crosswalk floor-mounted pedestrian signal light selectively illuminates red and green lights to match the red and green signals of traffic lights used to indicate whether to cross the crosswalk, allowing pedestrians and drivers to easily check whether to cross the crosswalk.

As a technology related to a conventional crosswalk floor-type pedestrian signal light, Korean Patent Publication No. 10-2022-0038305, "Energy-saving crosswalk pedestrian floor signal light with optimized light loss", has been proposed, which includes the following contents in the configuration of a crosswalk pedestrian floor lamp in which an angle is formed, and the reflective member has a width of 19 mm and a reflective member bending surface element that prevents bending or twisting of the reflective plate by bending both ends of the reflective member, and the reflective member is bent in a V shape with one side 19 mm and the opposite side 18 mm eccentrically, and has an element that prevents bending or twisting of the reflective plate, and the reflective member is bent in a V shape with one side 19 mm and the opposite side 18 mm eccentrically, and has an element that prevents bending or twisting of the reflective plate, and the reflective member has a width of 19 mm and both ends of the reflective member are bent to prevent bending or twisting of the reflective plate, and It has a reflective member folded surface element that prevents distortion, and is equipped with components in which each of the reflective members has a different angle.

However, such conventional technologies had the following problems:

First, conventional technology had the problem that multiple units had to be installed along the boundary between the crosswalk and the sidewalk, which inevitably led to the use of a large number of LEDs, which limited the ability to reduce power consumption, and because they were installed on the floor, it was difficult to reduce the number of LEDs used, making it difficult to improve cost-effectiveness.

Second, the conventional technology had the problem of requiring a lot of manpower and time for construction work according to the burial, connecting power cables underground, and maintenance and management, as it was buried in large numbers along the boundary between the crosswalk and the sidewalk.

In order to solve the problems of the prior art as described above, the present invention provides an indication to pedestrians and drivers of vehicles as to whether or not to walk by illuminating the boundary between a crosswalk and a sidewalk, thereby enabling the use of a smaller number of LEDs compared to the width of the crosswalk, thereby drastically reducing power consumption, and minimizing the manpower, time and cost required for construction work, maintenance and management work, etc. by eliminating the need for burying, etc., and also utilizing it for advertising purposes by illuminating text or designs, and increasing visibility by using a reflector in the light irradiated area.

Other objects of the present invention will be readily understood through the description of the following embodiments.

In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a floor lighting device for indicating pedestrian crossing is provided, comprising: a casing fixed to a post installed as a signal light or separately from a signal light in the vicinity of a crosswalk; and a light emitting unit installed in the casing and irradiating light of the same color as the signal light of the crosswalk to a boundary portion between the crosswalk and the sidewalk in conjunction with the signal light of the crosswalk.

The casing may further include a light guide provided on a side where light is irradiated from the light-emitting unit, and guiding the light to form a light irradiation area in the shape of a band at the boundary between the crosswalk and the sidewalk.

The above light-emitting section includes a plurality of LEDs arranged at intervals from each other in a direction corresponding to the length of the boundary portion, and each of the LEDs can have higher illuminance as the distance from the boundary portion increases, or can have the interval decrease as the distance from the boundary portion increases, or can have a number of LEDs forming an assembly arranged at intervals from each other increase as the distance from the boundary portion increases, thereby reducing the difference in brightness of the light irradiated area due to the distance difference at the boundary portion.

The above casing may further include a high-level lighting unit that is installed and illuminates the boundary portion to display an advertising design or advertising text.

The method may further include: a paint layer on which paint is applied to indicate a light irradiation area where light is irradiated from the light-emitting portion at the boundary portion; and a reflector contained in the paint layer so as to reflect the light.

According to the crosswalk pedestrian guidance floor lighting device according to the present invention, by illuminating the boundary between a crosswalk and a sidewalk, an instruction can be given to pedestrians and drivers of vehicles as to whether or not to walk, and as a result, a smaller number of LEDs can be used compared to the width of the crosswalk, thereby drastically reducing power consumption, and since burying, etc. is unnecessary, the manpower, time and cost required for construction work, maintenance and management work, etc. can be minimized, and the device can also be used for advertising purposes by illuminating text or designs, and has the effect of increasing visibility through the use of a reflector in the light irradiated area.

The present invention can have various modifications and various embodiments, and specific embodiments are illustrated in the drawings and described in detail. However, this is not intended to limit the present invention to specific embodiments, but should be understood to include all modifications, equivalents, or substitutes included in the technical spirit and technical scope of the present invention, and can be modified in various other forms, and the scope of the present invention is not limited to the following embodiments.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. Regardless of the drawing symbols, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof will be omitted.

FIG. 1 is a perspective view illustrating a floor lighting device for indicating pedestrians on a crosswalk according to an embodiment of the present invention, and FIG. 2 is a bottom view illustrating a light emitting part of a floor lighting device for indicating pedestrians on a crosswalk according to an embodiment of the present invention.

Referring to FIGS. 1 and 2, a floor lighting device (100) for indicating pedestrian crossing according to one embodiment of the present invention may include a casing (110) and a light emitting portion (120).

The casing (110) is fixed to a post (200) installed for use as a traffic light or separately from a traffic light near a crosswalk (4). Accordingly, the post (200) is installed for use as a traffic light, so that the traffic light can be installed together with it or separately from the traffic light. However, the post (200) can be installed to one side to avoid interference with pedestrians so as to be away from the pedestrian's path of movement.

The casing (110) has an internal space for accommodating a light-emitting unit (120) on the inside, but may have a structure in which this internal space is opened downward, and for example, it may be installed so as to face the boundary between a crosswalk (4) and a sidewalk (1), but may be installed on a post (200) installed on one side of this boundary to avoid interference with pedestrians, so that the open lower side may be installed slanted toward the boundary between the crosswalk (4) and the sidewalk (1), and may be installed so as to have an appropriate direction and angle depending on the position of the post (200).

The light emitting unit (120) is installed in the casing (110) and can be linked to the traffic light of the crosswalk (4) to irradiate light of the same color as the signal to the boundary between the crosswalk (4) and the sidewalk (1). Here, the area irradiated with light by the light emitting unit (120) is the boundary between the sidewalk (1) and the crosswalk (4), which may be the upper side of the boundary block (3) indicating the boundary between the sidewalk (1) and the roadway (2), but, alternatively, as in the present embodiment, it may be a portion corresponding to a position that avoids the boundary block (3).

The light-emitting unit (120) may include a signal receiving unit for receiving an operation signal for a signal from a traffic light via a wired cable or wireless communication such as Bluetooth, Zigbee or Wi-Fi in order to be linked to a traffic light, a control unit for outputting a control signal according to the signal received by the signal receiving unit, and an LED (121, 122, 123, 124, 125, 126, 127) that emits red light or green light identical to the signal of the traffic light under the control of the control unit, and this may be applied to all embodiments of the light-emitting unit below. Here, each of the LEDs (121, 122, 123, 124, 125, 126, 127) may be formed by a combination of a red LED and a green LED, but is not limited thereto, and may be formed by a multi-color LED that selectively emits red light and green light.

The light-emitting unit (120) is arranged in a plurality of positions with LEDs (121, 122, 123, 124, 125, 126, 127) spaced apart from each other in a direction corresponding to the length of the boundary between the crosswalk (4) and the sidewalk (1). This can be applied to the following embodiments of the light-emitting unit. Since the light-emitting unit (120) is installed at a position biased to one side in order to avoid interference with pedestrians, it cannot help but have a difference in distance with respect to the boundary between the crosswalk (4) and the sidewalk (1). Due to this, the illuminance can be made higher as the distance from the boundary is farther, and thus the difference in brightness of the light-irradiated area (10) due to the difference in distance at the boundary can be reduced. That is, the light-emitting unit (120) can be arranged so that the LEDs (121, 122, 123, 124, 125, 126, 127) use products with higher illuminance the farther they are from the light-irradiated area (10).

According to one embodiment of the present invention, a floor lighting device (100) for indicating pedestrian crossing may additionally be provided with a light guide (130) for guiding the irradiation of light and a high-level auxiliary lighting unit (140) for advertising, and a power supply unit (not shown) for supplying power required for operation from an external source.

The light guide (130) is provided on the side of the casing (110) where light is irradiated from the light emitting unit (120), and can guide the light to form a band-shaped light irradiation area (10) at the boundary between the crosswalk (4) and the sidewalk (1). This light guide (130) can have a slit-shaped edge shape to guide the light irradiated from the light emitting unit (120) to form a band, and can be made of a light reflective material to efficiently guide the light.

The high-level illumination unit (140) can be installed in the casing (110) and illuminates the boundary between the crosswalk (4) and the sidewalk (1) to display an advertising design or advertising phrase. The operation of this high-level illumination unit (140) is controlled by a control unit (not shown) that receives an operating signal transmitted from an external terminal or an operating signal generated by the operation of an operating unit provided on the outside, and can project light from an LED onto the image glass to illuminate the desired advertising design or advertising phrase onto the boundary. With the advertising lighting of this high-level illumination unit (140), not only is there almost no maintenance cost, but also content requested by the government, local governments, or individual businesses can be clearly displayed.

Referring to FIG. 3, a paint layer (150) and a reflector (160) may be provided in advance at the above-mentioned boundary portion. The paint layer (150) is provided with paint that is provided to indicate a light irradiation area (10) where light is irradiated from a light-emitting unit (120) at the boundary portion. This paint may be, for example, white paint, but is not limited thereto, and paints of various colors that enable identification may be used. The reflector (160) may be included in the paint layer (150) to reflect light irradiated from the light-emitting unit (120), thereby enhancing the identification of the light irradiation area (10). For example, a reflective material of various particles including glass pieces may be used.

Referring to FIG. 4, in order to reduce the difference in brightness of the light irradiation area (10; see FIG. 1) due to the distance deviation at the boundary, the light emitting unit (220) according to another example may be arranged so that the distance between the LEDs (221) decreases as the distance from the boundary increases, thereby serving to increase the array density of the LEDs (221) as the distance from the boundary increases, thereby compensating for the difference in brightness of the light irradiation area (10) due to the distance deviation at the boundary. Here, the illuminance or output of each LED (221) may be configured to be the same.

Referring to FIG. 5, in order to reduce the difference in brightness of the light irradiated area (10) due to the distance deviation at the boundary, the number of LEDs (321) forming an assembly in which each LED (321) is arranged at a greater distance from the boundary may increase as the distance from the boundary increases, thereby increasing the array density of the LEDs (321) as the distance from the boundary increases, thereby compensating for the difference in brightness of the light irradiated area (10) due to the distance deviation at the boundary.

According to the floor lighting device for indicating walking on a crosswalk according to the present invention, it is possible to indicate to pedestrians and drivers of vehicles whether to walk or not by illuminating the boundary between the crosswalk and the sidewalk, and as a result, a smaller number of LEDs can be used compared to the width of the crosswalk, thereby drastically reducing power consumption.

In addition, according to the present invention, since landfill, etc. are unnecessary, the number of personnel, time and cost required for construction work, maintenance and management work, etc. can be minimized.

In addition, according to the present invention, it can be used for advertising purposes by examining text or designs, and visibility can be improved by using a reflector in the light irradiated area.

Although the present invention has been described with reference to the attached drawings, it is obvious that various modifications and variations can be made within the scope that does not depart from the technical spirit of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims described below but also by equivalents of these claims.
