Description

가로등용 엘이디 등기구{The led lighting for street light}{LED lighting for street light}

본 발명은 가로등용 엘이디 등기구에 관한 것으로, 특히 엘이디모듈에서 방출되는 열에 SMPS가 영향을 받지 않으면서, SMPS에서 발생되는 열을 신속히 방출해주는 가로등용 엘이디 등기구에 관한 것이다.The present invention relates to an LED light fixture for a streetlight, and more particularly to an LED light fixture for a streetlight which rapidly dissipates heat generated in the SMPS without being affected by the SMPS in the heat emitted from the LED module.

일반적으로 가로등은 거리의 조명이나 교통의 안전을 위하여 보도나 차도를 따라 설치한 조명시설을 말한다. Generally, a streetlight is a lighting facility installed along a sidewalk or a roadway for the safety of street lighting or traffic.

즉, 매일 밤 특정한 시간대에 어두운 도로나 보도 같은 길에서 운전자나 보행자의 시야 확보를 통한 사고예방 및 범죄예방을 위해 길 가장자리에 높게 설치하는 등을 말하는 것이다.In other words, it means to prevent accidents by ensuring the visibility of drivers or pedestrians on dark roads or sidewalks at specific times every night, and to install them at the edge of the road for crime prevention.

종래의 가로등은 수은이나 형광 또는 나트륨 등을 광원으로 하는 등기구를 가로등 지주에 설치하여 사용하였지만, 최근에는 소비전력이 적게 소요되고 반영구적인 수명의 특성을 갖는 발광 다이오드(Light Emitting Diode; 이하,LED)를 조도 향상 및 소비전력 절감의 차원에서 등기구의 광원으로 많이 적용하고 있다.However, in recent years, light emitting diodes (hereinafter referred to as LEDs), which consume little power and have a semi-permanent lifetime, have been used as streetlights. However, Is widely applied as a light source of a luminaire in terms of improvement of illumination and reduction of power consumption.

이와 관련하여, 특허문헌1은 도로의 양측에 입설되는 지주의 상측에 설치되며, 내측에 엘이디모듈과 SMPS가 내설되어 빛을 조사하는 엘이디 가로등에 있어서, 외형은 유선형으로 형성되고 내측은 다각형상으로 형성되며 하측에 상기 엘이디모듈이 다수개 연결되는 프레임과; 프레임의 상면 전방에 길이방향으로 다수개의 방열핀이 돌출되어 엘이디모듈에서 발생되는 열을 방출하는 방열부와; 프레임의 상면 중앙부에 안착되어 SMPS에서 발생되는 열을 차단하는 장방형의 차단판과; 프레임의 하부를 감싸며 빛이 조사되도록 투명재질로 형성된 하부커버와; 프레임의 상면을 덮는 상부커버로 구성된 것을 특징으로 하는 엘이디 가로등을 제공하였다.In this connection, Patent Document 1 discloses an LED streetlight which is installed on the upper side of a pillar installed on both sides of a road and irradiates light with an LED module and an SMPS installed on the inside thereof. The LED streetlight has an outer shape formed in a streamline shape and an inner side formed in a polygonal shape A frame having a plurality of LED modules connected to a lower side thereof; A heat dissipating unit having a plurality of heat radiating fins protruded in the length direction in front of the upper surface of the frame to emit heat generated in the LED module; A rectangular blocking plate which is seated at the center of the upper surface of the frame to block heat generated in the SMPS; A lower cover formed of a transparent material so as to surround the lower portion of the frame and irradiate light; And an upper cover covering an upper surface of the frame.

하지만, 특허문헌1은 방열부에서 방출되는 열이 SMPS에 전달될 수 있었다.However, in Patent Document 1, heat emitted from the heat dissipating portion could be transferred to the SMPS.

또한, SMPS와 상부커버 사이에는 공간이 형성되어 있었기 때문에 SMPS에서 발생되는 열이 신속하게 상부커버 외부로 방출되기 어려웠었다.Also, since a space was formed between the SMPS and the upper cover, the heat generated from the SMPS was not easily released to the outside of the upper cover quickly.

이로 인해, SMPS의 온도가 상승하여 작동 오류가 발생할 수 있는 우려가 있었으며, 동시에 엘이디모듈에 대한 전원 공급 차질이 생길 수 있는 우려가 있었다.As a result, there is a concern that an operating error may occur due to an increase in the temperature of the SMPS, and there is a fear that power supply failure to the LED module may occur at the same time.

특허문헌1 : 국내 등록특허 제10-1132783호(2012. 05. 03. 등록공고)Patent Document 1: Domestic Registered Patent No. 10-1132783 (Registered on May 05, 2012)

이에 본 발명은, 엘이디모듈에서 방출되는 열에 SMPS가 영향을 받지 않으면서, SMPS에서 발생되는 열을 신속히 방출해주는 엘이디 등기구를 제공하는데 목적이 있다.Accordingly, it is an object of the present invention to provide an LED lamp that rapidly dissipates heat generated in the SMPS without being affected by the SMPS in the heat emitted from the LED module.

상기한 목적을 달성하기 위하여 본 발명은, 가로등 지주에 설치되는 가로등용 엘이디 등기구에 있어서, 내부에 구획단이 형성되고, 구획단 양측으로 각각 제1장착공간과 제2장착공간이 형성되며, 제1장착공간의 바닥면은 개방되고, 제2장착공간의 윗면은 개방되며 바닥면에는 발광구멍이 형성되고, 일측면에 가로등 지와 결합되는 지주연결부가 형성된 케이스와, 제1장착공간에 장착되는 SMPS와, 제2장착공간에 장착되고 SMPS로부터 전원을 공급받아 발광구멍으로 빛을 발광하는 엘이디모듈과, 제1장착공간을 마감하는 보호커버를 포함하되, 제1장착공간의 윗면에는 제1장착공간으로 함몰되어 SMPS와 밀착되는 방열단이 형성되고, 방열단의 내측에는 방열핀이 형성된 것을 특징으로 한다.According to an aspect of the present invention, there is provided an LED lighting device for a streetlight installed in a streetlight post, wherein a partition is formed in the interior, a first installation space and a second installation space are formed on both sides of the partition, A case having a bottom surface of the first mounting space opened, an upper surface of the second mounting space being open, a light emitting hole formed on the bottom surface, a case connecting portion being coupled to a street lamp on one side, An LED module mounted on the second mounting space and adapted to receive power from the SMPS to emit light into the light emitting hole, and a protective cover closing the first mounting space, wherein the first mounting space is provided with a first mounting And a heat dissipating step is formed in which the heat dissipating step is closely contacted with the SMPS, and a heat dissipating fin is formed inside the heat dissipating step.

본 발명은 구획단에 의해 엘이디모듈에서 방출되는 열이 SMPS에 전달되지 않는 효과가 있다.The present invention has the effect that the heat emitted from the LED module by the segment stage is not transmitted to the SMPS.

또한, 본 발명은 방열단이 SMPS에 밀착되기 때문에, 방열핀으로 SMPS에서 발생하는 열을 케이스 외부로 신속하게 방출해주는 효과가 있다.Further, since the heat dissipating end is closely attached to the SMPS, the present invention has an effect that the heat generated in the SMPS is rapidly discharged to the outside of the case with the heat dissipating fin.

더불어, 본 발명은 엘이디모듈의 열과 SMPS의 열이 구획단에 의해 서로 혼합되지 않고 각각 케이스 외부로 방출되는 효과가 있다.In addition, the present invention has the effect that the heat of the LED module and the heat of the SMPS are not mixed with each other by the divisional stages but are discharged to the outside of the case.

즉, 열에 의한 온도 상승에 의해 SMPS의 작동 오류를 막으면서, 동시에 엘이디모듈의 수명을 연장해주는 효과가 있다.That is, the temperature rise caused by the heat can prevent the operation error of the SMPS, and at the same time, the lifetime of the LED module can be extended.

다시 말해, 본 발명의 가로등용 엘이디 등기구의 수명을 연장하면서 교체비용을 줄일 수 있는 효과가 있는 것이다.In other words, it is possible to reduce the replacement cost while extending the service life of the streetlight lamp of the present invention.

그리고, 본 발명은 방열핀이 케이스의 외부로 돌출되지 않기 때문에, 외부에서 날아다니는 이물질의 걸림에 의한 방열핀의 손상을 막아주면서 동시에 SMPS의 열 방출을 방해하지 못하게 하는 효과가 있다.In addition, since the heat dissipation fins do not protrude to the outside of the case, the heat dissipation fins are prevented from damaging the heat dissipation fins due to the foreign matter flying from the outside, and at the same time, the heat dissipation of the SMPS can be prevented.

이때, 상기 지주연결부(14)는 가로등 지주(1)와 체결부재로 체결되는 체결구멍(14a)이 형성된다.At this time, the pillar connection part 14 is formed with a fastening hole 14a to be fastened by the fastening post 1 and the fastening member.

그리고, 상기 제1장착공간(12)의 윗면에는 제1장착공간(12)으로 함몰되어 바닥면이 SMPS(20)의 상면과 밀착되는 반시계 방향으로 90°로 기울어진 'ㄷ' 형태의 방열단(12a)이 형성되고, 상기 방열단(12a)의 내측에는 다수개의 방열핀(12a')이 돌출 형성된다.The upper surface of the first mounting space 12 is recessed into the first mounting space 12 so that the bottom surface of the SMPS 20 is in contact with the upper surface of the SMPS 20 in a counterclockwise direction, And a plurality of radiating fins 12a 'are protruded from the inside of the radiating end 12a.

여기서, 각 상기 방열핀(12a')은 케이스(10)의 외부로 돌출되지 않도록 형성된다.Here, each of the heat radiating fins 12a 'is formed so as not to protrude out of the case 10.

또한, 상기 방열단(12a)의 양측에는 체결단(12b)이 방열핀(12a')까지 돌출 형성되며, 상기 SMPS(20)의 양측에는 체결단(12b)과 함께 체결부재로 체결되는 체결단(20a)이 구비된다.A fastening end 12b is formed on both sides of the heat dissipating end 12a so as to protrude to the radiating fins 12a and fastened to both sides of the SMPS 20 with a fastening end 12b, 20a.

이때, 상기 SMPS(20)는 가로등 지주(1)를 통해 외부에서 전원을 공급받아 엘이디모듈(30)에 알맞는 전원으로 변환시켜 엘이디모듈(30)에 공급해준다.At this time, the SMPS 20 receives power from the outside through the streetlight post 1, converts the power into a power suitable for the LED module 30, and supplies the power to the LED module 30.

한편, 상기 제1장착공간(12)의 테두리 양측과 보호커버(40)의 테두리 양측에는 각각 체결부재로 체결되는 체결단(12c)과 체결구멍(41)이 각각 형성된다.On both sides of the rim of the first mounting space 12 and both sides of the rim of the protective cover 40, fastening ends 12c and fastening holes 41 are formed respectively by fastening members.

이때, 상기 보호커버(40)의 일단에는 끼움구멍(42)이 형성된다.At this time, one end of the protective cover 40 is formed with a fitting hole 42.

또한, 상기 지주연결부(14)가 형성된 케이스(10)의 일측면에는 고정단(10a)이 형성되며, 상기 고정단(10a)에는 일단이 보호커버(40)의 끼움구멍(42)에 끼움 결합되는 후크단(10b)의 타단이 회동되게 결합된다.A fixed end 10a is formed on one side of the case 10 having the support joint 14 and one end of the fixed end 10a is fitted into the fitting hole 42 of the protective cover 40 The other end of the hook end 10b is pivotally coupled.

한편, 상기 제2장착공간(13)이 형성된 케이스(10)의 일측면들은 제2장착공간(13)과 연통되는 방출구멍(10c)이 형성된다. On one side of the case 10, on which the second mounting space 13 is formed, a discharge hole 10c communicating with the second mounting space 13 is formed.

또한, 상기 구획단(11)은 제2장착공간(13)을 향해 보조구획단(11a)이 돌출 형성되며, 이때 상기 제2장착공간(13)은 2등분으로 구획된다.Also, the partitioning end 11 is formed with an auxiliary partitioning end 11a protruding toward the second mounting space 13, and the second mounting space 13 is divided into two equal parts.

더불어, 이등분으로 구획된 상기 제2장착공간(13)에는 엘이디모듈(30)의 체결구멍(31)과 함께 체결부재에 체결되는 체결단(13b)이 형성된다.In the second mounting space 13 defined by the bisector, a fastening end 13b fastened to the fastening member together with the fastening hole 31 of the LED module 30 is formed.

이때, 상기 엘이디모듈(30)은 방진방습 구조를 갖추고 있다.At this time, the LED module 30 has a dust-proof and moisture-proof structure.

다음은 상기와 같이 구성되는 본 발명의 작동 및 작용에 대해 살펴보기로 한다.Hereinafter, the operation and operation of the present invention will be described.

도 1 내지 도 5에 도시된 바와 같이, 상기 가로등용 엘이디 등기구(100)는 SMPS(20)의 체결단(20a)을 방열단(12a)에 형성된 체결단(12b)과 체결부재로 체결하여, 상기 SMPS(20)를 제1장착공간(12)에 장착하면서 SMPS(20)를 방열단(12a)에 밀착 고정한다.1 to 5, the LED lamp 100 for a streetlight is manufactured by fastening the fastening end 20a of the SMPS 20 with the fastening end 12b formed on the heat radiating end 12a and the fastening member, The SMPS 20 is closely fixed to the heat radiating end 12a while mounting the SMPS 20 in the first mounting space 12. [

그리고, 상기 보호커버(40)의 체결구멍(41)과 제1장착공간(12)의 체결단(12c)을 체결부재로 체결하고, 상기 고정단(10a)에 회동되게 결합된 후크단(10b)을 회동시켜 일단을 보호커버(40)의 끼움구멍(42)에 끼움 결합한다. The fastening hole 41 of the protective cover 40 and the fastening end 12c of the first mounting space 12 are fastened by a fastening member and the fastening end 10a is fastened to the hook end 10b So that one end is fitted in the fitting hole 42 of the protective cover 40. [

즉, 상기 보호커버(40)를 케이스(10)에 견고하게 고정 결합하여, 상기 제1장착공간(12)이 SMPS(20)을 위한 방진방습 구조로 갖추게 된다.That is, the protective cover 40 is firmly fixed to the case 10 so that the first mounting space 12 is provided with a dust-proof and moisture-proof structure for the SMPS 20.

그런 다음, 각 상기 엘이디모듈(30)의 체결구멍(31)과 제2장착공간(13)의 각 체결단(13b)을 체결부재로 체결하여, 상기 발광구멍(13a)으로 빛이 발광되도록 각 엘이디모듈(30)을 제2장착공간(13)에 장착한다. Then, the fastening holes 31 of the LED modules 30 and the fastening ends 13b of the second mounting space 13 are fastened with fastening members so that light is emitted to the light emitting holes 13a, And the LED module 30 is mounted in the second mounting space 13. [

그래서, 상기 가로등 지주(1)의 일단과 지주연결부(14)의 체결구멍(14a)을 체결부재 체결시켜, 상기 가로등용 엘이디 등기구(100)를 가로등 지주(1)에 고정 설치한다.One end of the streetlight column 1 and the fastening hole 14a of the column connecting portion 14 are fastened to each other to fix the streetlight lamp 100 to the streetlight column 1. [

그리고, 상기 SMPS(20)에서 엘이디모듈(30)에 전원을 공급하면, 상기 엘이디모듈(30)은 발광구멍(13a)으로 빛을 발광하여 도로나 보도를 비춘다.When power is supplied to the LED module 30 from the SMPS 20, the LED module 30 emits light to the light emitting hole 13a to illuminate the road or the sidewalk.

이때, 상기 엘이디모듈(30)은 제2장착공간(13)의 개방된 곳과 방출구멍(10c)으로 열이 방출하게 되면서, 상기 구획단(11)에 의해 SMPS(20)로 열이 전달되지 못하게 된다.At this time, as the LED module 30 emits heat to the open space of the second mounting space 13 and the discharge hole 10c, heat is not transferred to the SMPS 20 by the segment stage 11 I can not.

또한, 상기 보조구획단(11a)에 의해 제2장착공간(13)에 이등분으로 장착된 엘이디모듈(30)의 열은 서로 혼합되지 않고 케이스(10) 외부로 방출된다.In addition, heat of the LED module 30 mounted to the second mounting space 13 in a bisector by the auxiliary partitioning end 11a is discharged to the outside of the case 10 without being mixed with each other.

즉, 상기 보조구획단(11a)에 의해 엘이디모듈(30)의 열이 이등분으로 방출되는 것이다.That is, the heat of the LED module 30 is emitted by the auxiliary segment 11a.

한편, 상기 SMPS(20)에서 발생되는 열은 밀착된 방열단(12a)을 통해 다수개의 방열핀(12a')으로 용이하게 방출된다.On the other hand, the heat generated in the SMPS 20 is easily discharged to the plurality of heat dissipation fins 12a 'through the closely connected heat dissipation end 12a.
