Abstract
Description
[Technical field]
[0001] The present invention relates to a pedestrian crossing lighting bollard, and more particularly to a pedestrian crossing lighting bollard that is equipped with lighting and can irradiate light onto the pedestrian crossing. [Background technology]
[0002] Bollards are generally installed at the boundary between the roadway and the sidewalk to ensure the safety of pedestrians by blocking vehicles from entering the sidewalk and to prevent vehicles from parking or stopping on the sidewalk without permission.
[0003] Generally, bollards installed near pedestrian crossings are required to be constructed to withstand the impact of a vehicle collision and to prevent injury to pedestrians. Therefore, the inside of the bollard is usually constructed of a steel structure and the outside is made of urethane material, and reflective paper that reflects the light of vehicle headlights is attached to the body to improve visibility for vehicle drivers.
[0004] On the other hand, roads with little traffic are equipped with pedestrian crossings, but may not have crosswalk traffic lights. In particular, in areas with poor surrounding lighting, drivers may be careless and fail to notice pedestrians on the crosswalk. If drivers continue to drive their vehicles in this condition, there is a high risk of fatal accidents.
[0005] To solve this problem, technology has been developed that attaches lamps to bollards to shine light in the direction of the crosswalk.
[0006] However, bollards equipped with conventional lighting devices did not shine light onto the crosswalk for a long distance or over a wide area, making it difficult to ensure the safety of pedestrians. In addition, the LED light source was shone directly onto drivers and pedestrians, causing photophobia. [Prior art documents] [Patent documents]
[0007] [Patent Document 1] Korean Patent Publication No. 10-2013-0075160 [Patent Document 2] Korean Patent No. 10-1131851 Summary of the Invention [Problem to be solved by the invention]
[0008] The present invention is made to solve the above-mentioned problems, and aims to provide a pedestrian crossing lighting bollard that illuminates the crosswalk for a longer and wider distance, thereby ensuring pedestrian safety and preventing drivers and pedestrians from experiencing photophobia. [Means for solving the problem]
[0009] In order to achieve the above object, the present invention provides a crosswalk lighting bollard that includes: a main body that is long in the vertical direction and has a see-through window formed on a lower outer circumferential surface in the crosswalk direction; and a lower lighting member that is attached inside the main body and has a front portion disposed in the see-through window and irradiates light to the outside through the see-through window. The lower lighting member includes a first support plate that is coupled to and supported inside the main body; a first circuit board that is disposed on an upper portion of the first support plate; a first LED that is attached to an upper surface of the first circuit board so as to emit light upward from the upper surface of the first circuit board; a reflecting member that is disposed on an upper portion of the first LED and reflects the light emitted from the first LED forward in the direction of the see-through window; and a first cover lens that is coupled to the first support plate while covering the first circuit board, the first LED, and the reflecting member and has a front portion disposed in the see-through window. The light emitted upward from the first LED is reflected forward by the reflecting member, passes through the first cover lens, and is irradiated to the outside through the see-through window.
[0010] The reflective member has a semi-dome shape with an open front where the viewing window is located, and its lower part is fixed to the first support plate. The first LED is disposed inside the semi-dome shaped reflective member.
[0011] The first support plate has a blocking protrusion protruding from an upper portion of the first circuit board, the blocking protrusion protruding higher than the first LED, and the first LED is disposed rearward of the blocking protrusion.
[0012] The blocking protrusion prevents the first LED from being seen through the viewing window.
[0013] The blocking protrusion has a center portion facing the first LED, the center portion being recessed in a direction opposite to the first LED compared to both sides.
[0014] The light reflected by the reflecting member is irradiated toward a position lower than the middle of the viewing window.
[0015] The lower lighting member further includes a first inner lens that is disposed in front of the reflective member and is detachably attached to the inside of the first cover lens, and the first inner lens irradiates the light reflected through the reflective member more widely forward in the left and right directions.
[0016] The first inner lens has long embossed protrusions formed in the vertical direction and continuous in the horizontal direction on the front side, and the multiple embossed protrusions irradiate the light reflected by the reflective member widely forward in the horizontal direction.
[0017] the second circuit board is coupled to an upper part of the main body; a plurality of second LEDs arranged in a radial shape from an upper surface of the second circuit board and emitting light in an outer circumferential direction of the second circuit board; a second cover lens covering the circuit board and the second LEDs; a plurality of second inner lenses attached from an outer surface of the second cover lens along an outer circumferential surface of the second cover lens; and a cap covering the second cover lens and the second inner lens, the cap having a plurality of through holes formed at positions where the second inner lenses are arranged, the second inner lens being exposed to the outside through the through holes when the cap is attached, and light emitted laterally from the second LEDs passes through the second cover lens and the second inner lens and is then irradiated to the outside in a radial shape.
[0018] A hook is formed on the outer peripheral surface of the second cover lens, and a flange portion is formed protrudingly around the second inner lens, with the lower portion of the second inner lens seated on the hook and the flange portion being formed larger than the through hole. When the cap is attached, the second inner lens is inserted and positioned in the through hole, and the flange portion hooks onto the inner surface of the cap to fix the second inner lens. Effect of the Invention
[0019] As described above, the pedestrian crossing lighting bollard of the present invention has the following effects.
[0020] In the present invention, the lower lighting member can project light long and wide in front of the crosswalk to brightly illuminate the area, and the upper lighting member can project light laterally along the perimeter of the bollard to make the position of the bollard easily noticeable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0022] As shown in Figs. 1 to 8, the pedestrian crossing lighting bollard of the present invention comprises a main body (10), a lower lighting member (20), and an upper lighting member (30).
[0023] As shown in Figs. 1 and 2, the main body (10) is formed long in the vertical direction, and a viewing window (11) is formed in the outer peripheral surface of the lower part in the direction of the crosswalk.
[0024] The lower illumination member (20) is mounted inside the main body (10) and has a front surface facing the viewing window. (11) and irradiates light to the outside, i.e., the crosswalk, through the viewing window (11).
[0025] As shown in Figures 3 to 5, the lower illumination member (20) includes a first support plate (21), a first circuit board (22), a first LED (23), a reflective member (24), a first cover lens (25), etc.
[0026] The first support plate (21) is coupled to and supported within the body (10).
[0027] The first circuit board (22) is disposed on the upper part of the first support plate (21).
[0028] The first LED (23) is mounted on the top surface of the first circuit board (22) so as to radiate light upward.
[0029] The first support plate (21) is made of metal and has a function of dissipating heat generated from the first LED (23) and the first circuit board (22).
[0030] The reflecting member (24) is disposed above the first LED (23) and reflects the light emitted from the first LED (23) forward toward the viewing window (11).
[0031] The reflecting member (24) has a semi-dome shape with an open front where the viewing window (11) is disposed, and its lower portion is fixedly connected to the first support plate (21).
[0032] The first LED (23) is disposed inside the reflecting member (24) having a half-dome shape.
[0033] Therefore, the light emitted upward from the first LED (23) is reflected by the inner surface of the reflective member (24) having a semi-dome shape, and then is irradiated forward where the viewing window (11) is located.
[0034] At this time, the shape and structure of the reflecting member (24) are such that the light reflected by the reflecting member (24) is irradiated toward a position lower than the middle of the viewing window (11).
[0035] As a result, the light irradiated from the lower illumination member (20) through the viewing window (11) is not irradiated upward but only downward, thereby preventing photophobia.
[0036] The first cover lens (25) covers the first circuit board (22), the first LED (23) and the reflective member (24), and is coupled to the first support plate (21).
[0037] The first cover lens (25) has a front surface disposed in the viewing window (11).
[0038] Therefore, the light emitted upward from the first LED (23) is reflected forward by the reflective member (24), passes through the first cover lens (25), and penetrates the viewing window (11) to be irradiated to the outside.
[0039] The first support plate (21) has a blocking protrusion (21a) protruding from an upper portion of the first circuit board (22) so as to be higher than the first LED (23).
[0040] The first LED (23) is disposed rearward of the blocking protrusion (21a).
[0041] As described above, since the blocking protrusion (21a) is positioned forward of the first LED (23), when the lower lighting member (20) is viewed through the viewing window (11) positioned forward, the first LED (23) is hidden by the first blocking protrusion (21a) and cannot be seen.
[0042] Therefore, when the first LED (23) emits light, the bright light source point of the first LED (23) cannot be seen directly from the outside, so that photophobia and the like can be prevented.
[0043] The blocking protrusion (21a) is formed such that a center portion facing the first LED (23) is recessed from both sides in a direction opposite to the first LED (23).
[0044] As described above, the center of the blocking protrusion (21a) is formed concave and the blocking protrusion (21a) is spaced far away from the first LED (23), so that when the first LED (23) emits light, heat is directly transferred to the blocking protrusion (21a) to prevent deformation or short circuit.
[0045] The lower illumination member (20) may further include a first inner lens (26) disposed in front of the reflecting member (24) and detachably coupled to the inside of the first cover lens (25).
[0046] The first inner lens (26) expands the light reflected by the reflecting member (24) in the left-right direction and irradiates it forward.
[0047] For this reason, in this embodiment, the first inner lens (26) has an embossed protrusion (26a) that is long in the up-down direction and is continuously formed in the left-right direction on the front side.
[0048] The numerous embossed protrusions (26a) expand the light reflected by the reflecting member (24) in the left and right directions and irradiate it forward.
[0049] FIG. 9 is a diagram showing the results of an optical experiment when the first inner lens (26) was removed from a pedestrian crossing lighting bollard according to an embodiment of the present invention, and FIG. 10 is a diagram showing the results of an optical experiment when the first inner lens (26) was attached to a pedestrian crossing lighting bollard according to an embodiment of the present invention.
[0050] 9(a) and 10(a) show the state in which light is irradiated onto a pedestrian crossing.
[0051] FIG. 9(b) and FIG. 10(b) are plan views in a state where light is irradiated.
[0052] FIG. 9(c) and FIG. 10(c) are front views in a state where light is irradiated.
[0053] Comparing Figures 9(b) and 10(b) in detail, the length of the light shown in Figure 9(b), which is a drawing of the state in which the first inner lens (26) is removed, is longer than the length of the light shown in Figure 10(b), which is a drawing of the state in which the first inner lens (26) is attached, and the width of the light shown in Figure 9(b), which is a drawing of the state in which the first inner lens (26) is removed, is narrower than the width of the light shown in Figure 10(b), which is a drawing of the state in which the first inner lens (26) is attached.
[0054] In particular, looking closely at Figures 9(c) and 10(c), it can be seen that the width of the light in Figure 10(c) where the first inner lens (26) is attached is clearly wider than the width of the light shown in Figure 9(c) where the first inner lens (26) is removed.
[0055] Also, by looking closely at FIG. 9(c) and FIG. 10(c), it can be seen that in the present invention, light is irradiated toward a position lower than the center line, i.e., the middle of the viewing window (11).
[0056] As described above, the present invention makes it possible to vary the length or width of the light depending on whether the first inner lens (26) is attached or not, and it is possible to choose to project the light long or wide in the left and right directions depending on the environment in which the bollard is installed.
[0057] The upper illumination member (30) is attached to the upper part of the body (10).
[0058] As shown in Figures 6 and 8, the upper lighting member (30) includes a second circuit board (32), a second LED (33), a second cover lens (35), a second inner lens (36), a cap (37), etc.
[0059] The second circuit board (32) is coupled to the upper part of the body (10).
[0060] The second LEDs (33) are multiple and arranged in a radial pattern from the upper surface of the second circuit board (32), thereby emitting light in the outer periphery of the second circuit board (32).
[0061] The second cover lens (35) covers the second circuit board (32) and the second LED (33).
[0062] As shown in the drawings of this embodiment, a solar cell 38 or the like may be disposed between the second cover lens 35 and the second circuit board 32 .
[0063] The second inner lens (36) is made up of a plurality of lenses and is attached to the outer surface of the second cover lens (35) along the outer circumferential surface of the second cover lens (35).
[0064] The cap (37) covers the second cover lens (35) and the second inner lens (36).
[0065] The cap (37) has a number of through holes (37a) formed at positions where the second inner lens (36) is disposed.
[0066] With the cap (37) attached, the second inner lens (36) is exposed to the outside through the through hole (37a).
[0067] A catch (35a) is formed on the outer circumferential surface of the second cover lens (35), and a flange portion (36a) is formed to protrude from the periphery of the second inner lens (36).
[0068] The second inner lens (36) has a lower portion seated on the catch (35a).
[0069] The flange portion (36a) formed on the second inner lens (36) is larger than the through hole (37a).
[0070] With the cap (37) attached, the second inner lens (36) is inserted into the through hole (37a), and the flange portion (36a) is hooked onto the inner surface of the cap (37), thereby fixing the second inner lens (36).
[0071] With the above-mentioned structure, the light emitted laterally from the second LED (33) passes through the second cover lens (35) and the second inner lens (36) and is then irradiated to the outside in the form of radial rays.
[0072] As described above, the present invention is capable of illuminating a long and wide area in front of a crosswalk by using the lower lighting member (20), and illuminating the area brightly by using the upper lighting member (30) to illuminate the area laterally along the perimeter of the bollard, making it easy to identify the position of the bollard.
[0073] The pedestrian crossing lighting bollard of the present invention is not limited to the above-described embodiment, and may be modified in various ways within the scope of the technical concept of the present invention. [Explanation of symbols]
