Abstract

본 고안은 열 방출이 용이한 구형 조명등에 관한 것으로, 각각 다수의 엘이디가 실장되는 하부기판 및 상부기판과, 상기 하부기판과 상기 상부기판이 각각 하부와 상부에 결합 고정되는 판상의 기판지지부와, 상기 기판지지부의 하부와 상부에 각각 고정되며, 각각이 반구형인 하부커버 및 상부커버와, 상기 기판지지부의 상부 중앙부에 연결되며, 상기 상부커버의 중앙부를 통해 외부로 노출되는 지지부와, 상기 지지부의 끝단이 삽입 고정되는 결합부가 저면에 마련되는 방열판을 포함한다. 본 고안은 다수의 엘이디를 포함하는 기판을 지지하는 기판지지부의 측면부를 구형 커버의 외측으로 노출시킴과 아울러 상부측으로 열전달이 가능한 지지부를 사용하여 엘이디에서 발생된 열을 구형 커버의 상부외부로 전달하고, 그 지지부에 방열판을 결합하여, 엘이디에서 발생된 열을 방열시킴으로써, 구형 커버를 사용하는 조명등에서 엘이디의 방열효과를 높여, 엘이디의 수명 단축을 방지할 수 있는 효과가 있다.
