Description

발광, 반사 겸용 표지판Luminous, reflective signs
본 발명은 발광, 반사 겸용 표지판에 관한 것으로서, 더욱 상세하게는 검정색 숫자의 테두리부분과 빨간색 원부분만 빛이 투과되도록 하고, 나머지는 빛을 차단하거나 빛이 조사되지 않도록 함으로써 원거리에서도 정확하게 식별할 수 있도록 한 발광, 반사 겸용 표지판에 관한 것이다.The present invention relates to a light emitting and reflective signage, and more particularly, only the edge of the black number and the red circle can transmit light, and the rest can be accurately identified even from a long distance by blocking light or preventing light from being radiated. So it relates to a luminous, reflective and combined sign.
일반적으로 도로의 표지판 시설물에는 규제, 지시, 주의 및 보조표지에 해당하는 교통안전표지판과 도로의 현황을 안내하는 도로표지판 등이 있으며, 이들 기존의 표지판은 통상 알루미늄 재질의 베이스판재 위에 재귀반사지를 부착하여 문자나 도형을 표현하는 구조로 구성되어 있으며, 자동차의 전조등 불빛의 재귀반사를 통해 야간에도 표지판 상에 도안화된 문자나 도형의 식별이 용이하도록 되어 있다.In general, road signage facilities include traffic safety signs that correspond to regulations, directives, cautions, and supplementary signs, and road signs that provide information on the current state of the road. It is composed of a structure that expresses a character or a figure, it is easy to identify the character or figure drawn on the sign at night through the retroreflection of the headlights of the car.
그러나 상기와 같은 종래의 표지판들은 주변이 밝은 주간에는 비교적 표지판의 내용 식별이 용이하지만 야간과 같이 어두운 때에는 재귀반사에 의한 식별가능범위가 좁은 각도로 제한되고, 특히 산악도로, 급커브길, 공사구간 또는 고속주행을 위한 도로 등에 있어서는 운전자가 인지하는 거리가 짧기 때문에 비교적 근거리에 접근해야만 식별이 가능하게 되어 교통사고 발생의 위험성이 대단히 높다.However, the conventional signs as described above are relatively easy to identify the contents of the signs in the bright daytime, but in the dark, such as nighttime, the identifiable range by the retroreflective is limited to a narrow angle, especially mountain roads, sharp curve roads, construction sections. Alternatively, in the road for high speed driving, the driver perceives a short distance, so that identification is possible only when the driver approaches a short distance, and thus there is a high risk of a traffic accident.
특히 일교차가 큰 지역에서는 기온 차에 의해 표지판의 표면에 결로 현상이 발생하여 재귀반사의 특성을 완전히 상실하게 되어 도로표지판의 본연의 정보전달 기능을 전혀 수행하지 못하는 경우가 빈번하게 발생하기 때문에 이에 대한 대책 마련이 심각하게 요구되고 있는 실정이다.In particular, in areas with large crossovers, condensation occurs on the surface of the sign due to temperature differences, which completely loses the characteristics of retroreflective, and thus often fails to perform the original information transmission function of road signs. There is a serious demand for provision.
이러한 문제점을 일부 개선한 발명으로서 표지판의 내부에 형광등을 적용함으로써 피동적인 재귀반사의 한계를 벗어나 능동적인 발광이 가능한 내부조명식 도로표지가 제안된 바 있다.As an improvement to some of these problems, an internally illuminated road sign capable of actively emitting light has been proposed by applying a fluorescent lamp to the inside of a sign, thereby avoiding the limitation of passive retroreflection.
표지판의 내부에 형광등을 적용한 내부조명방식 표지판은 플렉스 재질 위에 실사출력 또는 칼라시트로 구성한 표지면을 발광 표시하기 위하여 그 내부에 조명장치를 내장하여 표지판 자체에서 빛이 발광하도록 구성되어 있다.The internal lighting method using fluorescent lamps inside the signboard is configured to emit light from the sign itself by incorporating a lighting device therein in order to display the cover surface composed of real output or color sheets on the flex material.
이와 같은 방식은 조명장치로서 20W 또는 40W의 삼파장 형광등을 사용하기 때문에 전력 소비가 비교적 높고, 잦은 형광등 교체 주기와 정기적인 표지면 세척이 요구되는 등의 별도의 유지관리가 추가된다는 단점이 있고, 시인성이 좋지 않아 원거리에서 정확하게 식별하지 못하는 문제점이 있었다. 따라서 초기에 몇몇 지역에서 시행된 이후 현재에 이르러서는 거의 사용되지 않고 있는 실정이다.This method has the disadvantage that the power consumption is relatively high because of the use of three-wavelength fluorescent lamps of 20 W or 40 W as the lighting device, and additional maintenance such as frequent replacement of the fluorescent lamp and the need for regular cleaning of the cover surface is added. This was not good, there was a problem that can not accurately identify from a distance. Therefore, since it was implemented in some areas at the beginning, it is rarely used at present.
한편, 외부에서 별도의 외부조명을 설치하여 표지판 전체를 비춰주는 외부조명방식도 안출되었으나 이 또한 조사되는 빛의 각도에 따라 식별성이 향상되는 범위가 좁은 각도로 제한되고, 오히려 조명강도를 높일수록 표지판 자체의 인지성은 높아지는 반면 과다한 반사로 인해 내용의 식별성은 떨어지게 되는 등의 문제가 있었다.On the other hand, the external lighting method that illuminates the entire sign by installing a separate external light from the outside has also been devised, but this is also limited to a narrow angle in which the identification is improved according to the angle of light to be irradiated, but rather the higher the intensity of the sign While there is a problem that the perception of the contents increases, the recognizability of the contents decreases due to excessive reflection.
또한, 상기 방식들의 표지판 외에 표지판의 문자 또는 도형의 윤곽을 따라 LED가 돌출식으로 부착된 표지판이 제안되기도 했는데, 이 기술은 표지면에 문자나 표시도형이 페인트 등으로 표시되고 그 표시도형을 발광 표시하기 위하여 표시도형의 형태를 따라 다수의 LED를 설치하여 발광 표시하도록 구성되어 있다.In addition, in addition to the signs of the above manner, there have been proposed signs in which LEDs are protruded along the outline of letters or figures of the signs, and this technology displays the letters or signs on the cover surface as paint and emits the signs. In order to display, a plurality of LEDs are provided along the shape of the display diagram to emit light.
LED를 설치하는 기술은 여러 구조로 개시되고는 있으나, LED 보호용 캡이나 커버들을 설치하여야 함에 따라 조도가 낮아진다는 단점이 있고, 이를 극복하기 위하여 고휘도 LED를 사용하는 경우 빛의 산란으로 인하여 원거리 식별이 거의 불가능하다는 단점이 있었다.Although LED installation technology has been disclosed in a number of structures, there is a disadvantage that the illuminance is lowered by installing caps or covers for protecting the LED, and in order to overcome this problem, when using high-brightness LEDs, remote identification is difficult due to scattering of light. The disadvantage was that it was almost impossible.
본 발명은 상기한 문제점을 해결하기 위하여 창안된 것으로, 본 발명의 목적은 검정색 숫자의 테두리부분과 빨간색 원형띠 부분만 빛이 투과되도록 하고, 나머지는 빛을 차단하거나 빛이 조사되지 않도록 함으로써 검정색 숫자와 빨간색 원의 시인성을 높여 원거리에서도 선명하고 정확하게 식별할 수 있도록 한 발광, 반사 겸용 표지판을 제공하는 데 있다.The present invention was devised to solve the above problems, and an object of the present invention is to allow light to pass through only the edge portion and the red circular band portion of the black number, and the rest to block the light or not to irradiate the black number. Its purpose is to provide a luminous and reflective sign that increases the visibility of the and red circles so that it can be clearly and accurately identified from a distance.

상기 도 1 내지 도 6b에 도시된 바와 같이, 본 발명에 따른 발광, 반사 겸용 표지판은 표시판 본체(10)와, 재귀반사시트(20)와, 제1엘이디모듈(30) 및 제2엘이디모듈(35)과, 교통표시 안내부(40)와, 커버판(50)과, 전원공급수단(60)으로 이루어져 있다.As shown in FIG. 1 to FIG. 6B, the light-emitting and reflective signs according to the present invention include a display panel body 10, a retroreflective sheet 20, a first LED module 30 and a second LED module ( 35), a traffic sign guide portion 40, a cover plate 50, and a power supply means 60.
상기 표시판 본체(10)는 확산판(11)과, 그 확산판(11)의 후면 가장자리에 원주를 따라 일정 높이로 돌출된 외측판(12)과, 그 외측판(12)의 안쪽으로 일정 거리 이격된 위치에 돌출된 중간구획판(13)과, 그 중간구획판(13)의 안쪽에 이격되어 돌출되는 내측구획판(14)으로 구성된다.The display panel main body 10 includes a diffuser plate 11, an outer plate 12 protruding at a predetermined height along a circumference at a rear edge of the diffuser plate 11, and a predetermined distance inward of the outer plate 12. An intermediate block plate 13 protruding at a spaced position and an inner compartment plate 14 spaced apart from the inside of the intermediate block plate 13 to protrude.
상기 확산판(11)은 빛의 확산을 위한 것으로, 공지의 확산판을 사용할 수 있고, 상기 외측판(12)과 중간구획판(13) 및 내측구획판(14)은 빛이 투과되지 않는 재질로 형성되거나 표면에 빛이 투과하지 못하는 재질로 된 시트가 부착될 수 있다.The diffusion plate 11 is for diffusion of light, and a known diffusion plate may be used, and the outer plate 12, the intermediate block plate 13, and the inner block plate 14 may not transmit light. Sheets made of a material or a material that does not transmit light to the surface may be attached.
따라서, 상기 외측판(12)과 중간구획판(13) 및 내측구획판(14)에 의해 구획된 각각의 공간은 서로 빛이 차단됨에 따라 인접되는 공간이 조명되더라도 그 조명빛이 전달되지 않게 된다.Therefore, the respective spaces partitioned by the outer plate 12, the intermediate partition plate 13, and the inner partition plate 14 are blocked from each other, so that the illumination light is not transmitted even if adjacent spaces are illuminated. .
상기 재귀반사시트(20)는 상기 확산판(11)의 전면 가장자리에 부칙되는 원형띠로 된 빨간색 반사시트(21)와, 그 빨간색 반사시트(21)의 안쪽 공간을 커버하도록 부착되는 하얀색 반사시트(22)와, 그 하얀색 반사시트(22)의 중앙부분에 교통표시를 안내하기 위해 부착되는 검정색 반사시트(23)로 구성된다.The retroreflective sheet 20 includes a red reflective sheet 21 having a circular band attached to the front edge of the diffuser plate 11 and a white reflective sheet attached to cover the inner space of the red reflective sheet 21. 22) and a black reflective sheet 23 attached to guide the traffic sign in the central portion of the white reflective sheet 22.
상기 재귀반사시트(20)는 통상의 교통표지판에 부착되는 반사시트와 동일규격으로 된 반사시트로서, 본 발명의 재귀반사시트는 빛의 반사는 물론, 빛의 투과가 가능한 것을 사용한다.The retroreflective sheet 20 is a reflective sheet having the same standard as a reflective sheet attached to a general traffic sign plate, and the retroreflective sheet of the present invention uses a light that can transmit light as well as reflect light.
빛을 투과시키는 이유는, 내부의 제1엘이디모듈과 제2엘이디모듈에서 조사되는 빛이 확산판을 투과하여 상기 재귀반사시트(20)의 중앙부분에 표기된 교통표시가 외부로 표출될 수 있도록 하기 위함이다.The reason for transmitting light is to allow the light emitted from the first LED module and the second LED module to pass through the diffuser plate so that the traffic sign displayed at the center of the retroreflective sheet 20 can be displayed to the outside. For sake.
본 발명은 재귀반사시트(20)의 부착으로 인해, 제1엘이디모듈과 제2엘이디모듈로 전원이 공급되지 않은 경우라도 교통표지판 본연의 기능을 수행할 수 게 된다.In the present invention, due to the attachment of the retroreflective sheet 20, even if power is not supplied to the first LED module and the second LED module, the traffic sign can perform its original function.
상기 빨간색 반사시트(21)는 확산판의 전면 가장자리에 부착되어 지되, 상기 확산판(11)의 후면에 설치되는 상기 외측판(12)과 중간구획판(13)의 사이부분을 커버하도록 부착되어지도록 하여 상기 제1엘이디모듈(30)의 엘이디 발광시 그 빛에 의해 표시판 본체의 전면 가장자리에 빨간색으로 된 원형띠가 표출되도록 한다.The red reflective sheet 21 is attached to the front edge of the diffuser plate, but is attached to cover the portion between the outer plate 12 and the intermediate compartment plate 13 installed on the rear of the diffuser plate 11. When the LED of the first LED module 30 emits light, a circular band of red color is displayed on the front edge of the display panel body by the light.
한편, 본 발명은 교통표시, 예로서 첨부 도면과 같이 제한속도를 표시하는 경우, 제한속도표시에 빛을 조사하여 그 제한속도가 표출되도록 하는 것이 아니라, 제한속도표시부분의 테두리부분이 조명되도록 하여 제한속도가 선명하게 식별될 수 있도록 한 것이다.On the other hand, in the present invention, when displaying the speed limit as shown in the traffic display, for example, the accompanying drawings, the speed limit display is not irradiated with light so as to express the speed limit, so that the edge portion of the speed limit display portion is illuminated The speed limit can be clearly identified.
구체적인 설명은 후술하기로 한다.Detailed description will be described later.
상기 제1엘이디모듈(30)은 상기 외측판(12)과 중간구획판(13)의 사이공간에 빛을 조사하도록 상기 중간구획판(13)의 외측면에 둘레를 따라 설치되는 것이고, 상기 제2엘이디모듈(35)은 상기 내측구획판(14)의 내측공간에 빛을 조사하도록 내측구획판(14)의 내측면에 둘레를 따라 설치되는 것이다.The first LED module 30 is installed along the circumference of the outer surface of the intermediate block plate 13 so as to irradiate light into the space between the outer plate 12 and the intermediate block plate 13, the first 2 LED module 35 is installed along the circumference on the inner surface of the inner partition plate 14 to irradiate light to the inner space of the inner partition plate (14).
상기 제1엘이디모듈과 제2엘이디모듈은 모두 기판과 그 기판에 설치된 엘이디로 구성되어 있고, 상기 전원공급수단(60)에 전선 연결되어 전원을 공급받아 발광하도록 구성되어 있다.The first LED module and the second LED module are both composed of a substrate and an LED installed on the substrate, is connected to the power supply means 60 is configured to emit light by receiving power.
이러한 상기 제1엘이디모듈(30)과 제2엘이디모듈(35)은 중간구획판(13)과 내측구획판(14)의 둘레를 따라 빙둘러 설치되거나, 첨부 도면과 같이 각각 선택된 간격으로 상호 이격된 채로 설치될 수 있다.The first LED module 30 and the second LED module 35 are installed around the middle compartment plate 13 and the inner compartment plate 14 around each other, or spaced apart from each other at selected intervals as shown in the accompanying drawings. Can be installed.
상기 전원공급수단(60)에는 전원의 공급을 제어하기 위해 스위치가 구비됨은 당연하다.Of course, the power supply means 60 is provided with a switch to control the supply of power.
상기 교통표시 안내부(40)는 상기 내측구획판(14)의 내측에 설치되는 것으로, 상기 제2엘이디모듈(35)의 빛이 확산판을 통해 투과되지 않도록 하기 위해 마련되어 지되, 상기 검정색 반사시트(23)의 부착부분과 대응되는 확산판(11)의 후면 해당 대응부분과 그 대응부분의 테두리를 따라 일정 거리 이격된 부분에 설치되어 진다.The traffic display guide portion 40 is installed inside the inner partition plate 14, and is provided to prevent the light of the second LED module 35 from being transmitted through the diffusion plate. A corresponding portion of the back side of the diffusion plate 11 corresponding to the attachment portion of the 23 and the portion spaced apart a predetermined distance along the edge of the corresponding portion.
즉, 상기 교통표시 안내부(40)는 상기 제2엘이디모듈(35)의 엘이디 발광시 상기 검정색 반사시트(23)의 테두리를 따라서만 빛이 투과되면서 조명될 수 있도록 안내하게 되는 것이고, 확산판을 투과하여 표시판 본체 정면으로 표출되는 빛에 의해 검정색 반사시트의 교통표시가 선명하게 식별될 수 있는 것이며, 원거리에서도 시인성을 유지할 수 있게 되는 것이다.That is, the traffic display guide portion 40 is to guide the light so as to transmit light only along the edges of the black reflective sheet 23 when the LED of the second LED module 35 emits light. The traffic display of the black reflective sheet can be clearly identified by the light that is transmitted through the front of the main body of the display panel, and visibility can be maintained even at a long distance.
이때, 상기 교통표시 안내부(40)는 상기 확산판(11)의 후면에 면접되게 형성될 수도 있고, 상기 확산판(11)의 전면에 상기 재귀반사시트(20)와 확산판(11) 사이에 위치하도록 형성될 수도 있는 것으로, 첨부도면에서는 확산판의 후면에 형성하였다.In this case, the traffic display guide part 40 may be formed to be interviewed on the rear surface of the diffusion plate 11, and between the retroreflective sheet 20 and the diffusion plate 11 on the front surface of the diffusion plate 11. It may be formed to be located in, in the accompanying drawings was formed on the back of the diffusion plate.
여기서, 교통표시를 안내하기 위해 부착되는 상기 검정색 반사시트(23)는 검정색이므로 빛의 투과가 거의 이루어지지 않기 때문에, 그 검정색 반사시트(23)와 대응되는 확산판의 후면 대응부분에 별도로 빛 차단을 위해 플레이트를 구비하지 않더라도 크게 문제가 되지 않을수도 있다.Here, since the black reflective sheet 23 attached to guide the traffic sign is black and thus hardly transmits light, the black reflective sheet 23 separately blocks light on the corresponding portion of the rear side of the diffuser plate corresponding to the black reflective sheet 23. Even if you do not have a plate for this may not be a big problem.
또한, 검정색 반사시트만을 빛이 투과되지 않은 시트로 마련하여 검정색 반사시트 부분은 빛의 투과가 이루어지지 않도록 하면서 그 검정색 반사시트의 테두리 외측부분만이 빛이 투과될 수 있도록 형성할 수도 있다.In addition, only the black reflective sheet may be provided as a sheet that does not transmit light, and thus the black reflective sheet portion may be formed such that only the outer portion of the edge of the black reflective sheet may transmit light while preventing light from being transmitted.
상기 커버판(50)은 상기 외측판(12)에 결합되어 상기 표시판 본체(10)의 내부를 폐쇄하도록 커버하는 구성이고, 상기 전원공급수단(60)은 상기 제1엘이디모듈(30)과 제2엘이디모듈(35)에 전원을 공급하기 위한 구성으로 상기 표시판 본체(10) 내부에 설치되거나 상기 커버판(50)에 설치될 수 있고, 또한 교통표지판과 인접하는 특정위치에 설치될 수 있다.The cover plate 50 is coupled to the outer plate 12 to cover the inside of the display panel body 10 so as to cover the inside, and the power supply unit 60 includes the first LED module 30 and the first unit. The 2 LED module 35 may be installed in the display panel body 10 or installed on the cover plate 50 to supply power to the LED module 35, and may be installed at a specific position adjacent to the traffic sign plate.
한편, 상기 중간구획판(13)과 내측구획판(14)의 사이 공간에는 빛의 차단을 위해 빛 차단판(70)이 설치된다.On the other hand, the light blocking plate 70 is installed in the space between the middle compartment plate 13 and the inner compartment plate 14 to block the light.
상기 빛 차단판(70)을 설치한 이유는, 상기 중간구획판(13)과 내측구획판(14)의 사이 공간에는 엘이디모듈이 설치되지 않음에 따라 그 공간과 인접된 확산판을 통해 빛이 투과되는 경우가 발생하지 않으나, 상기 중간구획판(13) 및 내측구획판(14)과 커버판(50) 사이의 틈새를 통해 인접 공간의 빛이 유입되는 경우가 발생될 수 있음에 따라 그 유입된 빛이 상기 확산판(11)을 투과하여 외부로 조사될 가능성이 있기 때문에 이를 차단하기 위함이다.The light blocking plate 70 is installed because the LED module is not installed in the space between the middle compartment plate 13 and the inner compartment plate 14. Although it does not occur, the inflow of light in the adjacent space may occur through the gap between the middle compartment plate 13, the inner compartment plate 14, and the cover plate 50. This is to block the light since the light may pass through the diffusion plate 11 and be irradiated to the outside.
상기와 같이 구성된 본 발명의 교통표지판이 설치된 상태에서, 주간에는 도 5와 같이 운전자의 육안확인으로 교통표시를 확인할 수 있다.In the state in which the traffic sign of the present invention configured as described above is installed, the traffic display can be confirmed by visual confirmation of the driver as shown in FIG.
그리고 야간에는 차량의 헤드라이트 빛이 교통표지판에 비춰지는 경우에 제1엘이디모듈과 제2엘이디모듈의 엘이디 발광유무에 상관없이 확산판 전면에 부착된 재귀반사시트(20)에 그 빛이 반사됨에 따라 운전자는 쉽게 교통표시를 식별하여 인지할 수 있게 된다(도 6a 참조).And at night, when the headlights of the vehicle are reflected on the traffic signs, the light is reflected on the retroreflective sheet 20 attached to the front of the diffuser plate regardless of whether the first LED module and the second LED module emit light. Accordingly, the driver can easily identify and recognize the traffic sign (see FIG. 6A).
또한, 차량의 헤드라이트 빛이 교통표지판에 비춰지지 않는 경우에는 제1엘이디모듈과 제2엘이디모듈의 엘이디 발광시 제1엘이디모듈의 빛에 의해 빨간색 반사시트(21)가 조명되고, 제2엘이디모듈의 빛에 의해 검정색 반사시트의 테두리부분이 조명되어 지는 것이고, 운전자는 원거리에서도 교통표시를 선명하게 식별할 수 있게 된다(도 6b 참조).In addition, when the headlight light of the vehicle is not illuminated on the traffic sign, the red reflective sheet 21 is illuminated by the light of the first LED module when the LEDs of the first LED module and the second LED module emit light, and the second LED The edge of the black reflective sheet is illuminated by the light of the module, and the driver can clearly identify the traffic sign even at a long distance (see FIG. 6B).
이와 같이, 본 발명은 확산판 전체에 빛을 투과시켜 빨간색과 하얀색 및 검정색의 모든 반사시트를 통해 빛이 조명되도록 하는 것이 아니라, 빨간색과 검정색 반사시트의 테두리부분만을 조명시키도록 하여 교통표시를 선명하게 식별할 수 있도록 한 것으로, 시인성의 향상으로 원거리에서도 정확하게 교통표시를 식별하여 인지할 수 있게 된다.As such, the present invention transmits light through the entire diffuser plate so that the light is not illuminated through all of the red, white, and black reflective sheets, and only the edges of the red and black reflective sheets are illuminated to make the traffic display clear. In order to be able to easily identify, it is possible to identify and recognize traffic signs accurately even at a long distance due to improved visibility.
