Description

환기구를 가지는 엔벨로프를 포함하는 램프Lamp including envelope with vent
본 발명은 환기구를 가지는 엔벨로프를 포함하는 램프에 관한 것으로, 구체적으로는 램프 내외부의 공기를 순환시킬 수 있는 환기구를 가지는 엔벨로프를 포함하여 구성되는 램프에 관한 것이다.The present invention relates to a lamp comprising an envelope having a vent, specifically relates to a lamp comprising an envelope having a vent that can circulate air inside and outside the lamp.
램프 기술의 지속적인 발전에도 불구하고, 전기 에너지의 빛으로의 전환에 따른 물리적 한계에 의하여, 램프의 광효율은 그 램프의 종류에 따라 달라질 수 있으나, 통상적으로 5 ~ 20% 수준에 그친다. 이에 따라 램프에서 상기 전기 에너지의 상당 부분은 열로 소모되어 버릴 뿐만 아니라, 이로 인하여 발열에 의한 이차적인 문제까지 야기하게 된다.Despite the continuous development of lamp technology, due to the physical limitations of the conversion of electrical energy to light, the light efficiency of the lamp may vary depending on the type of lamp, but typically only 5-20%. As a result, not only a large portion of the electrical energy in the lamp is consumed as heat, but also causes secondary problems due to heat generation.
램프의 온도가 올라갈 경우, 램프의 성능을 열화시키거나 고장의 원인이 될 수 있는데, 예를 들어 CFL(Compact Fluorescent Lamp)의 경우, 고온으로 인하여 효율이 낮아질 수 있고, 더 나아가 장시간 고온 점등 상태가 지속될 경우 광속이 감퇴되거나 흑화 현상이 나타날 수 있다. 또한 LED의 경우, 고온에 노출됨으로써 발광 효율이 낮아질 수 있고, 더 나아가 접합부 온도(junction temperature)가 내구 온도 이상으로 상승할 경우, LED 구조가 손상을 입을 수 있다.If the temperature of the lamp rises, it may deteriorate the lamp performance or cause a failure. For example, in case of CFL (Compact Fluorescent Lamp), the efficiency may be lowered due to the high temperature. If it persists, the luminous flux may be reduced or blackening may occur. In addition, in the case of LED, the light emission efficiency may be lowered by being exposed to high temperature, and further, when the junction temperature rises above the endurance temperature, the LED structure may be damaged.
따라서, 램프의 성능과 안정성을 위하여 온도 상승을 효과적으로 억제할 수 있는 구조가 요구되지만, 외부로부터 발광체 및 구동회로 등을 보호하거나, 사용자가 매우 밝은 발광체를 직시하는 것을 방지하기 위한 엔벨로프(envelope)가 그 내외부 공기의 순환을 방해하는 구조적인 문제점이 해결되지 못하고 있어, 램프의 온도 상승을 효율적으로 억제할 수 있는 구조가 구현되지 못하고 있다.Therefore, a structure capable of effectively suppressing the temperature rise is required for the performance and stability of the lamp. However, an envelope is provided to protect the light emitter and driving circuit from the outside, or to prevent the user from facing the bright light emitter. The structural problem that hinders the circulation of the internal and external air has not been solved, and a structure capable of effectively suppressing a temperature rise of the lamp has not been implemented.
종래 램프의 발열에 의한 문제를 해결하기 위해서는 방열판 등을 이용한 방법이 많이 이용되었다. 대한민국 등록특허 제10-1052894(2011. 7. 25. 등록)에서는 LED 램프용 히트 싱크 등을 개시하고 있는데, 이는 도 1에서 볼 수 있는 바와 같이, 발광체 등을 보호하기 위한 엔벨로프에 대한 개선이 아닌 방열을 위한 방열핀(100)를 포함하는 방열 박스(110) 구조를 개시하고 있다. 그러나, 이러한 구조만으로 엔벨로프 내부의 뜨거워진 공기의 온도를 충분히 낮출 수 있다고 말하기 어렵다. 발광체 등에서 발산되는 열은 엔벨로프 내부의 공기 온도를 크게 상승시킬 수 있으므로 엔벨로프 내부 공기의 온도를 보다 근본적으로 낮출 수 있도록, 엔벨로프 내부와 외부의 공기를 순환시켜 램프의 온도를 효율적으로 낮출 수 있는 구조를 가지는 램프가 필요하다.In order to solve the problem caused by the heat generation of the conventional lamp, a method using a heat sink and the like has been used a lot.

또한, 플라스틱 재질로 상기 엔벨로프(240)를 구성할 경우, 유리에 비해 훨씬 적은 열전도도를 가지는 플라스틱의 특성상 엔벨로프(240) 내부의 온도가 유리에 비해 훨씬 높고, 그 결과로 엔벨로프(240) 자체의 온도도 유리의 경우보다 높아질 수 있는데, 상기와 같이 상당한 크기의 환기구(250)를 포함함으로 인하여 내부의 온도를 밀폐된 유리를 사용할 때보다 훨씬 낮게 유지할 수 있고, 엔벨로프(240) 재질의 내열성 밀 열변색의 문제도 억제할 수 있게 된다.In addition, when the envelope 240 is formed of a plastic material, the temperature inside the envelope 240 is much higher than that of the glass due to the characteristics of the plastic having much less thermal conductivity than the glass, and as a result, the envelope 240 itself. The temperature may also be higher than that of glass, and by including the ventilation holes 250 of a considerable size as described above, the internal temperature may be kept much lower than when using the closed glass, and heat-resistant mill heat of the envelope material 240 may be used. The problem of discoloration can also be suppressed.

As can be seen here, the envelope 240 may include a top cover 310, a side cover 320, and a base cover 330, and vent holes through which air may enter or exit between the covers. 250 may be present, and each cover may be superimposed so that the user cannot directly contact the light emitting unit 210 inside the lamp from the outside through the ventilation hole 250. Through this structure, a path through which air inside and outside the lamp circulates is secured, thereby effectively suppressing a temperature increase of the lamp.

Lamp using a stem-branch structure according to an embodiment of the present invention, a plurality of light emitting unit 210, including a cover containing a LED, a substrate and an LED mounted on the substrate, fixed to the lamp base lamp A stem structure part 410 forming a central axis shape of the branch structure part connecting the plurality of light emitting parts 210 and the stem structure part 410 to fix the plurality of light emitting parts 210 at predetermined positions ( 420 and a driving unit 220 including a circuit for driving the light emitting unit 210. In addition, the branch structure part 420 provides a passage for wiring between the light emitting part 210 and the driving part 220, and the plurality of light emitting parts 210 are fixed at respective predetermined positions to thereby emit adjacent light. The ventilation port 250 is formed between the parts 210, thereby forming the shape of the envelope 240 including the ventilation port 250.
상기와 같은 구조를 통하여 상기 램프 내외부의 공기가 순환될 수 있게 함으로써, 상기 LED를 포함하여 구성되는 발광부(210) 또는 상기 LED에 대한 구동 회로가 포함된 구동부(220)의 발열에 의한 램프 내부의 온도 상승을 효과적으로 억제할 수 있게 된다.By allowing the air inside and outside the lamp to circulate through the structure as described above, inside the lamp due to heat generated by the light emitting unit 210 including the LED or the driving unit 220 including the driving circuit for the LED. It is possible to effectively suppress the temperature rise.
이때, 상기 LED가 장착되는 기판으로 투광성 기판을 사용함으로써 LED 후면으로 방사되는 빛의 손실을 줄일 수 있고, LED 발광 효율을 개선하기 위하여 사용하는 반사경을 적용하는 경우와 비교하더라도 LED 발광 효율을 더욱 개선할 수 있게 된다. 또한, 더 바람직하게는 알루미나를 비롯한 세라믹 계통의 투광성 기판을 사용함으로써 열전도성 특성도 함께 개선할 수 있다. 또한, 여기서 더 나아가, 상기 LED와 상기 커버를 이용하여 리포트 포스퍼(remote phosphor) 구조를 형성하도록 구성하는 것도 가능하다.At this time, by using a light-transmissive substrate as the substrate on which the LED is mounted, it is possible to reduce the loss of light radiated to the back of the LED, and further improve the LED luminous efficiency even when applying a reflector used to improve the LED luminous efficiency. You can do it. In addition, more preferably, by using a ceramic-based light-transmissive substrate including alumina, the thermal conductivity can be improved. It is also possible to further configure here to form a report phosphor structure using the LED and the cover.
여기서, 리모트 포스퍼(remote phosphor) 구조라 함은 일반적으로 LED 칩을 패키징할 때 베이스에 칩을 실장하고 그 칩 위에 형광체를 도포하여 백색 LED를 만드는 것과 달리, 청색 LED 칩을 칩 베이스, 또는 기판 위에 직접 실장하고 플라스틱 계열의 커버를 사출할 때 형광체를 함께 섞어 사출하여 LED 칩으로부터 발생한 청색광을 형광체에서 적색, 또는 녹색광으로 변환하는 과정을 거치도록 만드는 구조를 말한다. 다시 말하면, 백색광을 만드는 형광체를 패키징 단위에서 도포하고 그 위에 커버를 씌우는 것이 아니라 커버 자체에 형광체를 포함시키는 구조이다. 이를 통해 LED와 형광체 사이의 거리를 이격하여 형광체의 열화를 방지하고 발광 면적을 넓힘으로써 광효율을 개선할 수 있게 된다.Here, the remote phosphor structure refers to a blue LED chip on a chip base or a substrate, in contrast to mounting a chip on a base and applying a phosphor on the chip when the LED chip is packaged. It is a structure that makes the process of converting the blue light generated from the LED chip from phosphor to red or green light by directly mixing and ejecting the phosphor together when ejecting the plastic cover. In other words, the phosphor which produces white light is not applied to the packaging unit and covered with the cover, but the phosphor is included in the cover itself. Through this, it is possible to improve the light efficiency by separating the distance between the LED and the phosphor to prevent deterioration of the phosphor and widen the light emitting area.
이와 함께, 상기 발광부(210)의 하부 즉, 상기 LED가 장착되는 기판의 하부에 방열판 등의 방열 구조를 추가로 사용함으로써 발광부(210)의 발열을 도와 상기 램프의 성능을 개선하고 안정성을 높일 수도 있다.In addition, by using a heat dissipation structure such as a heat sink in the lower portion of the light emitting unit 210, that is, the lower portion of the substrate on which the LED is mounted, it helps to generate heat of the light emitting unit 210 to improve the performance of the lamp and improve stability.

As shown in FIGS. 9A and 9B, the light emitting unit 210 is positioned below the driving unit 220, and the envelope 240 includes the light emitting unit 210 and includes an envelope high. It is fixed to the driving unit 220 by using the government 910, based on the vertical axis of the light emitting unit 210 and the driving unit 220, the lower ventilation hole 920 is provided in the lower portion of the envelope 240 The upper ventilation hole 930 may exist at the upper portion of the envelope 240.
보다 구체적으로, 상기 구동부(220)는 외부 전원과의 연결 수단을 제공하는 전원연결부(230)로부터 전원을 공급받아 상기 발광부(210)를 구동하여 소정의 빛을 발광시키게 된다. 예를 들어, 상기 발광부(210)가 CFL(Compact Fluorescent Lamp) 등 형광 램프인 경우, 상기 구동부(220)는 안정기 회로를 포함하여 구성될 수 있고, 상기 발광부(210)가 LED 발광 소자를 이용하여 구성되는 경우에는, LED 구동 회로를 포함하여 상기 구동부(220)를 구성할 수 있다.More specifically, the driving unit 220 receives power from the power connection unit 230 providing a connection means with an external power source to drive the light emitting unit 210 to emit a predetermined light. For example, when the light emitting unit 210 is a fluorescent lamp such as a compact fluorescent lamp (CFL), the driving unit 220 may include a ballast circuit, and the light emitting unit 210 may include an LED light emitting device. In the case of using the LED driver circuit, the driver 220 may be configured to include an LED driver circuit.
