Description
본 고안은 광원인 램프의 방열에 의한 세트의 온도 상승의 억제에 관한 화상투영장치에 관한 것이다.The present invention relates to an image projection apparatus relating to suppression of temperature rise of a set by heat radiation of a lamp which is a light source.
종래의 화상투영장치의 방열 및 단열 구조는 도1과 도2와 같이 하우징(1)으로 찬공기를 흡입되는 흡입팬(8)과, 상기 흡입팬(8)에서 흡입된 찬공기로 냉각되는 램프(4)와, 상기 램프(5)를 램프홀더(4)에 탄성력을 이용하여 고정되는 스프링(6)과, 상기 램프홀더(4)가 삽입되어 결합 고정되는 램프케이스(2)가 구비되였다.The heat dissipation and heat insulating structure of the conventional image projection apparatus has a suction fan 8 that sucks cold air into the housing 1 as shown in FIGS. 1 and 2, and a lamp that is cooled by cold air sucked by the suction fan 8. (4), a spring 6 for fixing the lamp 5 to the lamp holder 4 by using an elastic force, and a lamp case 2 for inserting and fixing the lamp holder 4 is provided.
그리고, 상기 램프케이스(2)의 후면에는 흡입팬(8)에서 흡입되어 램프(5)를 냉각시킨 공기를 배출할 수 있도록 횡방향으로 구성된 공기배출구멍(3)과, 상기 공기배출구멍(3)으로 배출되는 공기를 강제로 배출하는 냉각팬(7)이 구비되였다.On the rear surface of the lamp case 2, an air discharge hole 3 formed in a horizontal direction so as to discharge air cooled by the suction fan 8 and cooling the lamp 5, and the air discharge hole 3 Cooling fan 7 for forcibly discharging the air discharged to the) was provided.
이상과 같이 구성된 화상투영장치의 방열 및 단열 구조는 램프(5)에서 발생되는 고온의 열을 흡입팬에서 흡입된 찬공기로 냉각시켜 램프의 열을 최대한 억제시켜 주어야 한다.The heat dissipation and heat insulation structure of the image projection apparatus configured as described above should cool the high temperature heat generated from the lamp 5 with cold air sucked from the suction fan to suppress the heat of the lamp as much as possible.
그런데, 흡입팬(8)에서 흡입된 찬공기가 램프(5)로 이동되는 동안 찬공기의 상태를 유지하지 못한다.However, while the cold air sucked in the suction fan 8 is moved to the lamp 5, the cold air cannot be maintained.
그러므로, 램프(5)의 직접적인 발열부인 아이크(9)와 반사경(10)을 냉각시키기 때문에 램프(5)에서 발생되는 열이 제대로 냉각되지 못하고, 램프케이스(2)의 후면에 있는 공기배출구멍(3)으로 배출된 공기를 냉각팬(7)에 의해 강제로 배출되므로 램프(5)로부터 발생하는 열을 충분히 냉각시키지 못하는 문제점이 있었다.Therefore, since the heat generated from the lamp 5 is not properly cooled because the ike 9 and the reflector 10, which are the direct heating parts of the lamp 5, are cooled, the air discharge hole at the rear of the lamp case 2 ( Since the air discharged to 3) is forcibly discharged by the cooling fan 7, there is a problem that the heat generated from the lamp 5 cannot be sufficiently cooled.
따라서, 램프(5)로부터 발생되는 열이 하우징 내로 방사됨으로 인해 세트 내부온도의 상승 및 기타 부품에 영향을 줌으로서 전체적으로 열에 의한 피해가 발생하는 문제점이 있었다.Therefore, the heat generated from the lamp 5 is radiated into the housing, thereby causing an increase in the internal temperature of the set and other components, thereby causing damage due to heat as a whole.
그리고, 램프케이스(2)에서 열을 효과적으로 차단하여 주지 못함으로서 보다 많은 방열이 발생하며 램프케이스(2)의 공기배출구멍(3)이 횡방향으로 되어 있고 냉각팬(7)이 원형으로 되어있기 때문에 공기 흐름이 맞지 않아 효과적인 냉각이 이루어지지 않는 문제점이 있었다.In addition, the heat dissipation occurs more effectively by not blocking heat in the lamp case 2, and the air discharge hole 3 of the lamp case 2 is in the lateral direction, and the cooling fan 7 is circular. Due to the air flow does not fit there was a problem that the effective cooling is not made.
본 고안은 이러한 점을 감안하여 고안한 것으로서, 램프케이스의 양측면과 하면을 단열부로 구성하고, 램프홀더의 상면을 단열부로 구성하며, 하우징에 공기유도관을 설치하여 흡입팬에서 흡입된 찬공기를 공기유도관을 통과하여 램프의 발열부인 아이크 및 반사경에 직접 전달하여 냉각 효과를 좋게하고, 하우징내의 온도 상승 및 기타 부품에 대한 온도의 영향을 최소화하여 온도에 대한 안전성과 하우징의 신뢰성 확보에 그 목적이 있다.The present invention has been devised in view of the above points, and both sides and the bottom of the lamp case are composed of a heat insulating part, the upper surface of the lamp holder is composed of a heat insulating part, and an air induction pipe is installed in the housing to suck the cold air sucked from the suction fan. Passes through the air induction pipe directly to the heat generating part of the lamp and reflector to improve the cooling effect, and to minimize the effect of temperature rise on the housing and the temperature of the other parts to ensure the safety of the temperature and the reliability of the housing There is this.
