Further, said little spademan is positioned at heat radiation main body upper end, and little spademan is the spill cavity, empty cavity in surrounding in the middle of the plural little spademan.
Further, the outside of said disjunctor lens is provided with protecgulum, and protecgulum is positioned at heat radiation main body top.
Further, said disjunctor lens body has plural lenses, lens of the corresponding disjunctor lens of each LED lamp.
Further, be the cavity of interior sky in the middle of the said little spademan, be provided with aluminium base, LED lamp, disjunctor lens in the cavity of little spademan, the top of little spademan is provided with protecgulum.
Further, said body inboard is provided with three connecting holes, and connecting hole connects the plastic cement base, and the plastic cement base is provided with power supply.
The utility model is reasonable in design; Little spademan, big spademan, inner chamber are set on radiator; The heat that the LED bulb lamp is produced is discharged by little spademan, big spademan, inner chamber through air stream, has improved the radiating effect of LED bulb lamp, greatly reduces the operating ambient temperature of led light source; Protect led chip effectively, prolonged the service life of LED bulb lamp.
