Description

전등의 기밀 유지장치{omitted}Light-retaining device {omitted}

본 발명은 수중등, 가로등, 투광기 등 빛을 비추는 전등의 내부가 기밀을 유지하도록 하는 전구의 기밀 유지장치에 관한 것으로써, 좀더 구체적으로는 램프의 구동 유무에 따라 하우징의 내부에 온도 편차가 발생하더라도 기밀을 유지하는 패킹(packing)이 변형되지 않도록 하여 전등의 내부 기밀이 유지되도록 하는 전구의 기밀 유지장치에 관한 것이다.The present invention relates to an airtight holding device of a light bulb to keep the inside of a light that illuminates a light such as a submersible lamp, a street lamp, a floodlight, and more specifically, a temperature deviation occurs inside the housing depending on whether the lamp is driven. Even if the airtight packing (packing) to maintain the confidentiality of the light bulb so that the internal airtightness of the lamp is maintained so as not to be deformed.

일반적으로 빛을 비추는 수중등, 가로등, 투광기 등(이하 '전등'이라 함)을 구성하는 하우징의 내부에는 빛을 발광하는 램프가 설치되어 있고 상기 램프가 설치된 기판에는 전원을 인가하는 케이블이 연결되어 있다.In general, a lamp that emits light is installed in a housing constituting an underwater light, a street lamp, a floodlight (hereinafter, referred to as a “light”) that emits light, and a cable for applying power is connected to the board on which the lamp is installed. have.

이러한 전등은 외부에 설치되거나, 수중에 설치됨에 따라 누전(漏電)이 발생되지 않도록 하우징의 내부가 항상 기밀을 유지하고 있어야만 된다.Such a lamp must be kept airtight inside the housing so that no electric leakage occurs due to the external installation or the underwater installation.

도 1은 종래 수중등의 일 실시예를 나타낸 종단면도로써, 하우징(1)의 내부에 기판(2)이 스크류(3)에 의해 고정 설치되어 있고 상기 기판에는 케이블(4)을 통해 인가되는 전원에 의해 빛을 발광하는 적어도 1개 이상의 램프(5)가 설치되어 있으며 하우징(1)과 케이블(4)의 사이에는 기밀을 유지하기 위한 패킹(6)이 설치되어 있다.1 is a longitudinal sectional view showing an embodiment of a conventional underwater light, the substrate 2 is fixed to the inside of the housing 1 by a screw (3) and the power applied to the substrate through a cable (4) At least one lamp 5 for emitting light is provided, and a packing 6 for maintaining airtightness is provided between the housing 1 and the cable 4.

그리고 하우징(1)의 상부에는 램프(5)에서 발광된 빛을 외부로 투광하는 렌즈(7)가 설치되어 있고 상기 하우징(1)과 렌즈(7)의 접속면에는 기밀을 유지하기 위한 패킹(8)이 설치되어 있으며 상기 렌즈(7)는 커버(9)에 의해 덮어져 보울트(10)로 고정되어 있다.And the upper part of the housing (1) is provided with a lens (7) for transmitting the light emitted from the lamp (5) to the outside and the packing for maintaining airtightness on the connection surface of the housing (1) and the lens (7) 8) is installed and the lens 7 is covered by a cover 9 and fixed with a bolt 10.

따라서 케이블(4)을 통해 기판(2)에 전원이 인가됨에 따라 램프(5)가 발광하면 발광된 빛이 렌즈(7)를 통해 외부로 투광되므로 전등으로써, 역할을 하게 된다.Therefore, when the lamp 5 emits light as power is applied to the substrate 2 through the cable 4, the emitted light is transmitted through the lens 7 to the outside, thereby serving as a lamp.

그러나 이러한 종래의 전등은 하우징(1)의 내부가 패킹(6)(8)에 의해 기밀을 유지하는 과정에서 램프의 구동 유무 또는 외기의 온도 변화에 따라 하우징(1)의 내부에 있던 공기가 팽창되거나, 수축될 때 기밀을 유지하는 패킹(6)(8)이 하우징(1)의 내부 압력 변화에 따라 함께 그 형상이 변형되어 파손되므로 하우징(1)의 내부로 습기가 들어와 누전을 일으키는 원인으로 작용되었다.However, in the conventional lamp, the air inside the housing 1 expands according to whether the lamp is driven or the temperature of the outside air is changed while the inside of the housing 1 is kept airtight by the packings 6 and 8. Or the packing (6) (8), which keeps airtight when it shrinks, is deformed and damaged together with the change in the internal pressure of the housing (1), causing moisture to enter the interior of the housing (1) and cause a short circuit. It worked.

즉, 외기의 온도가 높은 하절기 낮 또는 램프(5)가 발광하면 하우징(1)의 내부 온도가 급격히 상승되므로 기밀을 유지하는 패킹(6)(8)이 팽창되었다가 외기의 온도가 낮은 밤이나, 램프가 점멸되면 하우징(1)의 내부 온도가 떨어짐에 따른 압력 저하로 패킹(6)(8)이 수축하는 작용이 반복적으로 이루어짐에 따라 하우징(1)의 내부 기밀을 유지하는 패킹(6)(8)이 찢어지거나, 변형되어 결국 하우징(1)의 내부에 습기가 들어와 누전을 일으키게 된다.That is, when the temperature of the outside air is high during the summer or when the lamp 5 emits light, the internal temperature of the housing 1 is rapidly increased, so that the packing (6) 8 which maintains airtightness is expanded and then the night when the outside temperature is low. When the lamp flashes, the packing 6 for maintaining the airtightness of the housing 1 as the packing 6 and 8 shrinks repeatedly due to a pressure drop as the internal temperature of the housing 1 drops. (8) is torn or deformed, and moisture eventually enters the interior of the housing 1, causing a short circuit.

본 발명은 이와 같은 종래의 문제점을 해결하기 위해 안출한 것으로써, 그 구조를 개선하여 램프의 구동 유무 또는 외기의 온도 편차에 따라 하우징의 내부 온도가 변화되더라도 하우징의 공기 압력을 항상 일정하게 유지하여 기밀을 유지하는 패킹이 훼손되는 현상을 미연에 방지할 수 있도록 하는데 그 목적이 있다.The present invention has been made to solve such a conventional problem, by improving the structure, even if the internal temperature of the housing changes depending on whether the lamp is driven or the temperature deviation of the outside air to maintain a constant air pressure of the housing at all times The purpose of this is to prevent the phenomenon that the packing to maintain the airtight damage in advance.

상기 목적을 달성하기 위한 본 발명의 형태에 따르면, 하우징의 내부에 케이블을 통해 전원이 인가됨에 따라 발광하는 적어도 1개 이상의 램프가 설치되고 상기 하우징의 상부에는 투광을 위한 렌즈가 설치된 것에 있어서, 하우징에 공기통과공을 형성하고 상기 공기통과공의 내 측에 위치하는 하우징에는 하우징의 내부 공기 압력에 의해 변형되는 캡을 씌워 하우징의 내부를 실링하도록 된 것을 특징으로 하는 전등의 기밀 유지장치가 제공된다.According to an aspect of the present invention for achieving the above object, at least one lamp which emits light when power is applied through a cable is installed in the housing, and a lens for light transmission is installed on the housing. The airtight hole is formed in the housing located on the inner side of the air through hole is provided with an airtight holding device of the lamp characterized in that the cap is deformed by the internal air pressure of the housing to seal the inside of the housing. .

본 발명은 하우징에 공기통과공이 형성되어 있고 공기통과공의 내 측으로는 하우징의 내부에 존재하는 공기의 압력 변화에 따라 함께 변형되면서 내부에 존재하는 공기를 하우징의 외부로 배출하거나, 흡입하는 캡이 설치되어 있어 하우징의 내부 기밀을 유지하는 패킹에 가해지는 압력을 항상 일정하게 유지하게 되므로 하우징의 내부로 습기가 유입되는 현상을 근본적으로 차단할 수 있게 되고, 이에 따라 누전에 따른 전등의 파손은 물론이고 인명피해를 줄일 수 있게 되는 효과를 얻게 된다.The present invention is formed with an air through hole in the housing and the inner side of the air through the deformed together in accordance with the pressure change of the air present in the interior of the air discharged inside the outside of the housing, or the cap for suction Since the pressure applied to the packing that maintains the inside airtightness of the housing is kept constant at all times, it is possible to fundamentally block the inflow of moisture into the inside of the housing. The effect is to reduce the casualties.

이하, 본 발명을 일 실시예로 도시한 도 2를 참고하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to FIG. 2 as an embodiment.

도 2는 본 발명의 구성을 나타낸 종단면도로써, 본 발명의 구성 중 종래의 전등 구조와 동일한 부분은 그 설명을 생략하고 동일 부호를 부여하기로 한다.Figure 2 is a longitudinal sectional view showing a configuration of the present invention, the same parts as the conventional light structure of the configuration of the present invention will be omitted with the same reference numerals will be given.

본 발명은 하우징(1)의 내부에 기판(2)이 설치되어 있고 상기 기판(2)에는 케이블(4)을 통해 전원이 인가됨에 따라 발광하는 적어도 1개 이상의 램프(5)가 설치되어 있으며 하우징(1)의 상부에는 투광을 위한 렌즈(7)가 설치되어 있는데, 상기 케이블(4) 및 렌즈(7)는 각각 패킹(6)(8)에 의해 하우징(1)과 기밀을 유지하도록 되어 있다.According to the present invention, a substrate 2 is installed inside the housing 1, and the substrate 2 is provided with at least one lamp 5 that emits light when power is applied through the cable 4, and the housing 2 is installed. The upper part of the (1) is provided with a lens (7) for light transmission, the cable (4) and the lens (7) is to maintain the airtight with the housing (1) by the packing (6) (8), respectively. .

그리고 하우징(1)에 공기통과공(11)이 형성되어 있고 상기 공기통과공(11)의 내 측에 위치하는 하우징(1)에는 하우징(1)의 내부 공기 압력에 의해 변형되는 캡(12)이 씌워져 하우징(1)의 내부를 실링(sealing)하도록 되어 있다.An air passage hole 11 is formed in the housing 1, and a cap 12 deformed by the internal air pressure of the housing 1 is disposed in the housing 1 located inside the air passage hole 11. This cover is made to seal the inside of the housing 1.

이 때, 상기 캡(12)은 공기통과공(11)의 내 측에 위치됨과 동시에 기밀이 유지되도록 설치 고정하면 되지만, 본 발명의 일 실시예로 도시한 도 2에서는 하우징(1)의 내부에 위치하는 공기 압력에 의해 캡(12)이 팽창, 수축되는 과정에서 보다 안정적으로 기밀을 유지하도록 공기통과공(11)의 내 측으로 돌출봉(13)을 형성하여 상기 돌출봉(13)에 캡(12)을 씌워 실러(14)로 이들 사이의 기밀을 유지하도록 되어 있는데, 이 때 돌출봉(13)에 캡(12)을 씌운 다음 스냅 링(도시는 생략함) 등의 고정부재로 캡(12)을 고정한 다음 실러(14)로 견고히 고정하는 것이 보다 바람직하다.At this time, the cap 12 is located on the inner side of the air passage hole 11 and at the same time it may be installed and fixed to maintain the airtight, in Figure 2 of the embodiment of the present invention in the interior of the housing (1) The cap 12 is formed on the protruding rod 13 by forming a protruding rod 13 inwardly of the air passage hole 11 to maintain the airtightness more stably in the process of expanding and contracting the cap 12 by the air pressure. 12) to seal the airtight between them with the sealer 14, in which the cap 12 is put on the protruding rod 13, and then the cap 12 with a fixing member such as a snap ring (not shown). ) Is more preferably fixed firmly with the sealer 14.

상기 하우징(1)의 내부 압력에 의해 변형되는 상기 캡(12)의 크기(용적률)는 하우징(1)의 내부 온도변화에 따라 압력의 변화에 차이가 발생되므로 전등의 용도 및 크기에 따라 적절한 크기로 설계하는 것이 바람직하며, 그 재질은 고무재질이면 어떠한 재질이라도 무관하나, 온도 및 압력 변화에 따른 내구성을 고려하여 실리콘재질로 하는 것이 보다 바람직하다.The size (volume rate) of the cap 12, which is deformed by the internal pressure of the housing 1, may vary depending on the change in pressure according to the internal temperature change of the housing 1, and thus may be appropriately sized according to the use and size of the lamp. It is preferable to design the material, and the material may be any material as long as it is a rubber material, but it is more preferable to use a silicon material in consideration of durability according to temperature and pressure changes.

따라서 하우징(1)의 내부에 설치된 램프(5)가 발광하지 않거나, 외기의 온도가 그다지 높지 않을 경우에는 하우징(1)의 내부 압력이 거의 대기압(1kg/㎠) 상태를 유지하게 되므로 도 2에 나타낸 바와 같이 캡(12)이 원형상태를 유지하고 있다.Therefore, when the lamp 5 installed inside the housing 1 does not emit light or the temperature of the outside air is not very high, the internal pressure of the housing 1 is maintained at almost atmospheric pressure (1 kg / cm 2). As shown, the cap 12 remains in a circular state.

그러나 케이블(4)을 통해 램프(5)에 전원을 인가하여 점등시키거나, 외기의 온도가 높은 하절기 낮에는 램프(5)의 발광에 따른 열 또는 외기의 온도에 따라 하우징(1)의 내부 온도가 급격히 상승하므로 하우징(1)의 내부에 존재하는 공기의 압력 또한 급격히 상승하게 된다.However, the internal temperature of the housing 1 may be turned on by applying power to the lamp 5 through the cable 4, or depending on the heat or the temperature of the outside air caused by light emission of the lamp 5 during the summertime when the temperature of the outside air is high. Since the temperature rises sharply, the pressure of air existing inside the housing 1 also rises rapidly.

이와 같이 하우징(1)의 내부에 존재하는 공기 압력이 상승하여 팽창하면 공기통과공(11)의 내부에 위치되어 있던 캡(12)이 공기의 팽창량만큼 수축하면서 캡(12)의 내부에 있던 공기를 공기통과공(11)을 통해 하우징(1)의 외부로 배출하면서 찌그러져 하우징(1)의 내부 용적률을 증대시키게 되므로 하우징(1)의 내부 압력은 상승하지 않게 된다.As such, when the air pressure existing inside the housing 1 rises and expands, the cap 12 positioned inside the air passage hole 11 contracts by the amount of air expansion, and thus the inside of the cap 12 Since the air is crushed while the air is discharged to the outside of the housing 1 through the air passage 11, the internal volume ratio of the housing 1 is increased, so that the internal pressure of the housing 1 does not increase.

따라서 하우징(1)과 케이블(4)의 사이, 그리고 하우징(1)과 렌즈(7)의 사이에 설치되어 이들 사이의 기밀을 유지하는 패킹(6)(8)은 램프(5)의 구동 유무 또는 외기의 온도 변화에 관계없이 변형되지 않고 이들 사이에서 실링(sealing)을 유지 하게 된다.Therefore, the packings 6 and 8, which are installed between the housing 1 and the cable 4 and between the housing 1 and the lens 7 and maintain the airtight therebetween, are driven by the presence of the lamp 5. Or it does not deform regardless of the temperature change of the outside air to maintain a sealing (sealing) between them.

한편, 점등되어 있던 램프(5)가 점멸되거나, 외기의 온도가 떨어지면 하우징(1)의 내부 온도가 떨어지게 되므로 하우징(1)의 내부에 존재하는 공기의 압력 또한 떨어지게 된다.On the other hand, when the lamp 5 that is lit flashes or the temperature of the outside air falls, the internal temperature of the housing 1 drops, so that the pressure of air existing inside the housing 1 also drops.

이에 따라, 하우징(1) 내의 압력이 떨어져 공기의 부피가 줄어들게 됨에 따라 공기의 부피가 줄어드는 양만큼 외부의 공기가 공기통과공(11)을 통해 캡(12)의 내부로 유입되면서 캡(12)을 본래의 형태로 복원시키게 되므로 패킹(6)(8)이 수축되는 현상을 방지하게 된다.Accordingly, as the pressure in the housing 1 drops and the volume of air is reduced, the outside air flows into the inside of the cap 12 through the air passage hole 11 by the amount of the volume of the air, thereby reducing the cap 12. By restoring the original form to prevent the phenomenon that the packing (6) (8) shrinks.

이러한 동작은 램프(5)의 동작 유무, 그리고 외기의 온도 변화에 따라 반복적으로 진행되면서 하우징(1)의 내부 압력을 항상 일정하게 유지하게 되므로 패킹(6)(8)이 변형되거나, 훼손되는 현상을 방지하게 되는 것이다.This operation is repeatedly performed according to the operation of the lamp 5 and the temperature change of the outside air, and thus the packing 6 and 8 are deformed or damaged since the internal pressure of the housing 1 is always kept constant. Will be prevented.

본 발명의 기술사상은 상기한 바람직한 실시예에 따라 구체적으로 기술되었으나, 전술한 실시예들은 그 설명을 위한 것이며, 그 제한을 위한 것이 아님을 주의하여야 한다.Although the technical spirit of the present invention has been described in detail according to the above-described preferred embodiment, it should be noted that the above-described embodiments are for the purpose of description and not of limitation.

또한, 본 발명의 기술분야에서 통상의 전문가라면 본 발명의 기술사상의 범위 내에서 다양하게 변화하여 실시할 수 있음은 이해 가능한 것이다.In addition, it will be understood by those skilled in the art that various changes can be made within the scope of the technical idea of the present invention.
