PURPOSE: An LED bulb is provided to effectively dissipate heat by utilizing a housing which includes a fixing frame made of a heat dissipating material and heat dissipation fins. CONSTITUTION: A base(12) is installed at one side of a bulb body(10). A housing(20) includes multiple ventilation parts(24) and heat dissipation fins(26). A spherical light cover(30) is installed at the lower part of the housing. A fixing frame(40) is installed perpendicularly inside the light cover. The fixing frame is combined with the housing. White LED PCBs(54) and color LED PCBs(56) are installed alternately at a plural LED lighting component(50). A lighting selection control unit(60) selects white light from the white LED PCBs, or color light from the color LED PCBs for lighting. |
