An LED bulb is provided to effectively radiate the generated heat to the outside by employing a lens receiving hole on the surface of a front cover. A front cover(6) includes a lens hole and a bolt fixing stand(6-1) arranged on the rear side of the front cover. A main body(7) consists of a bolt fixing hole, a plurality of side ventilation openings(8), a heat radiating groove, a socket joining hole, a thermally conductive substrate(9), a lens(4,19) and a electric wire passage. The main body is made of thermal conductive metals. The heat radiating groove is formed clockwise or counterclockwise. The cross section of the side ventilation opening is square or oval. A socket(12) is comprised of a drive substrate(13), an electrode hole, a guide unit(10) and a fastening part. |
