종래의 조명기구는 백열전구와 트랜스포머(transformer)와 스타터(starter)를 이용한 형광등 기구가 주로 이용되었으며, 최근에는 반도체소자를 이용한 전자식 안정기를 이용한 첨단 조명기구가 많이 사용되고 있다. 그런데, 조명기구의 점등 시에 아크 서어지(arc surge)와 전자파를 발생시켜 인접한 전자설비에 악영향을 미치는 경우가 있다. 따라서, 민감한 전자설비의 주위에 설치된 조명기구에 대해서는 전자설비에 악영향을 미치는 아크 서어지나 전자파를 방지할 필요성이 있다.Conventional lighting fixtures are mainly used incandescent lamps, fluorescent light fixtures using a transformer (transformer) and starter (starter), and recently, high-tech lighting fixtures using electronic ballasts using semiconductor devices have been used a lot. However, when the lighting device is turned on, arc surge and electromagnetic waves may be generated to adversely affect adjacent electronic equipment. Therefore, it is necessary to prevent the arc surge and the electromagnetic wave which adversely affect the electronic equipment with respect to the lighting fixture installed around the sensitive electronic equipment.

또한, 저전압으로 동작되는 반도체 소자로 구성된 전자식 안정기의 경우, 낙뢰 및 서어지와 같은 이상전압에 취약하여 잦은 고장과 파손으로 많은 피해가 발생 하고 있다. 특히, 우중이라도 조명기구가 고장이나 파손이 나면 큰 손해가 발생할 수 있는 극장이나 공연장의 경우, 낙뢰 및 서어지와 같은 이상전압에 따른 조명기구의 고장이나 파손을 절대 방지해야 하기 때문에 이를 해결해야 할 필요성이 있다.In addition, the electronic ballast composed of a semiconductor device operated at a low voltage is vulnerable to abnormal voltages such as lightning and surge, causing a lot of damage due to frequent failures and breakages. Especially, in the case of theaters or theaters where even if the lighting fixtures break down or break down even in the rain, the lighting fixtures must be prevented due to abnormal voltages such as lightning strikes and surges. There is a need.

따라서, 본 발명의 기술적 과제는, 전원공급선으로 유입되는 서어지와 같은 이상 전압을 제거하여 고장이나 손상을 방지하여 보다 안정적으로 조명을 확보하고 유지관리 비용을 절감할 수 있는 조명기구를 제공하는 것이다.Accordingly, the technical problem of the present invention is to provide a lighting fixture that can more stably secure lighting and reduce maintenance costs by removing abnormal voltages such as surges flowing into the power supply line to prevent breakdown or damage. .
