At the problems referred to above of prior art, the purpose of this utility model provides a kind of good looking appearance LED lamp with structure improved radiator of good heat dissipation effect simultaneously.

For achieving the above object, a kind of LED lamp of the present utility model with structure improved radiator, comprise lamp holder, radiator, LED and aluminium base, LED is arranged on the aluminium base, aluminium base is arranged at the radiator top, lamp holder is arranged at the radiator bottom, lamp holder is electrically connected with LED, radiator comprises aluminium inserts and heat-dissipating casing, heat-dissipating casing comprises internal layer shell and outer casing, internal layer shell is coated on the lateral surface of aluminium inserts, and the gap between internal layer shell and the outer casing is provided with radiating fin, and outer casing is provided with blow vent.

Wherein, blow vent is arranged on the top of outer casing and the bottom of outer casing.

Wherein, the aluminium inserts is the aluminium inserts of hollow, all is provided with fixing hole and cable-through hole on the end face of aluminium inserts and the aluminium base, and aluminium base is bolted on the end face of aluminium inserts by fixing hole.

Wherein, the LED lamp also comprises connector, lamp holder is the lamp holder of hollow, the medial surface of lamp holder and the lateral surface of lamp holder are provided with screw thread, internal layer shell is provided with screw thread, the two ends of connector are provided with screw thread, and an end of connector and the medial surface of lamp holder are spirally connected, and the other end and the internal layer shell of connector are spirally connected.

Wherein, the LED lamp also comprises lampshade, the top socket of lampshade and heat-dissipating casing.

Wherein, lampshade and outer casing socket.

Wherein, heat-dissipating casing is a plastic casing.

The beneficial effects of the utility model are: radiating fin is arranged on the radiator the inside, appearance looks elegant is generous, simultaneously on outer casing, have blow vent and be used for circulation of air, strengthened the heat loss through convection effect of radiator and air, the radiating effect of radiator is not affected because of radiating fin is arranged on the radiator the inside.
