Description
본 발명은 딥 드로잉 방식을 이용한 벌브형 등기구에 관한 것으로, 더욱 상세하게는 벌브형 등기구의 제작시 등기구를 구성하는 램프 몸체를 딥 드로잉 방식으로 일체로 제작하여 이음매가 생기지 않도록 함으로써 발광체인 LED모듈로부터 발생되는 열을 방열체인 램프 몸체로 효과적으로 전달하여 방열효율을 극대화 할 수 있도록 함과 아울러 외관미를 향상시킬 수 있도록 하는 딥 드로잉 방식을 이용한 벌브형 등기구에 관한 것이다.The present invention relates to a bulb-type luminaire using a deep drawing method, and more particularly, to fabricate the lamp body constituting the luminaire when the bulb-type luminaire is manufactured in a deep drawing method to prevent the seam from being produced from the LED module which is a light emitting body. The present invention relates to a bulb-type luminaire using a deep drawing method that effectively transfers generated heat to a lamp body, which is a heat sink, to maximize heat dissipation efficiency and to improve appearance.
조명등으로서 오랜동안 필라멘트를 채용한 램프를 사용하여 오다가 반도체 기술의 발달로 반도체에 전압을 가할 때 발생되는 발광현상을 이용한 광원인 LED(light emitting diode; 발광다이오드)로 빠르게 대체되고 있다.As a lamp, a lamp employing a filament for a long time is used, and the semiconductor technology is rapidly being replaced by a light emitting diode (LED), which is a light source using a light emitting phenomenon generated when a voltage is applied to a semiconductor.
이러한 LED를 이용한 램프는 기존 백열전구에 비해 전력 소모량은 적고, 수명은 길면서 밝고 선명하며, 색상과 휘도에 따라 다양한 조명연출이 가능하여, 신호등, 조명스탠드, 간판, 손전등, 소형램프 등과 같이 다양한 분야에서 일반 조명용으로 사용이 확산될 전망이다.Lamps using these LEDs consume less power than conventional incandescent bulbs, have a long life, and are bright and clear, and are capable of producing a variety of lights according to color and brightness, and can be used for various purposes such as traffic lights, lighting stands, signs, flashlights, and small lamps. In the field, it is expected to be used for general lighting.
LED 램프에 사용되는 LED 소자는 종래의 필라멘트 광원에 비해 발열량이 적고, 소비전력이 적으며, 긴 수명과 내충격성을 갖고 있다. 또한, 제조과정에서 형광등과 같이 수은이나 방전용 가스를 사용하지 않으므로 환경오염을 유발하지 않는 장점이 있다.The LED element used in the LED lamp has less heat generation, less power consumption, and longer life and impact resistance than the conventional filament light source. In addition, since mercury or a discharge gas is not used, such as a fluorescent lamp, the manufacturing process has an advantage of not causing environmental pollution.
그러나, 고휘도 고출력의 광원을 얻기 위하여 LED 소자에 구동전류를 증가시키게 되면, LED 소자의 전력손실이 증가 되어 대부분의 전기에너지가 열로 변환되고 LED 소자의 접합부분이 고온상태로 된다. LED 소자는 흐르는 전류가 일정하더라도 접합부분의 온도가 높아지면 광출력과 광효율이 저하될 뿐만 아니라 동작 수명도 줄어드는 특성이 있다. 따라서, 조명성능과 동작수명을 향상시키기 위해서는 LED 소자의 접합부분에서 발생 되는 열을 최대한 빠르게 외부로 방출해 주어야 한다. However, when the driving current is increased in the LED device to obtain a light source of high brightness and high power, the power loss of the LED device is increased, so that most of the electric energy is converted into heat and the junction of the LED device is in a high temperature state. Even if the current flowing through the LED is constant, if the junction temperature rises, the light output and the light efficiency are not only reduced, but the operating life is also reduced. Therefore, in order to improve lighting performance and operation life, the heat generated at the junction of the LED device should be discharged to the outside as soon as possible.
