After the utility model adopts said structure, the fast characteristic of outer logical heat dissipation channel heat loss through conduction of radiator, and form the heat radiation that some heat radiation page or leaf sheets increase area of dissipation along inwall.Radiator fan realizes accelerating the mobile technique effect of air of heat dissipation channel; The radiator radiator that said radiator is the polygon cylinder is arranged on the middle part of lamp body; Each side correspondence of radiator is provided with aluminium base and lamp pearl; But each face all luminous lighting is realized the technique effect that many light-emitting areas are shone, and improves the utilization rate illumination effect whole with increasing lamp body of light fixture.Lampshade is olivary revolution makes the peripheral technique effect of realizing the uniformly light-emitting illumination of lamp body.Through heat dissipation channel logical outside in radiator, being provided with; The heat of circuit board is directly transferred in the radiator; Making full use of the heat dissipation channel heat radiation of outwards circulating realizes making the fluorescent tube internal heat negotiable; Each several part is distribute heat evenly, the gathering of a certain specified point heat can not take place, thereby has prolonged the service life of light fixture.
The further improvement project of the utility model:
The above-mentioned high effect radiator of a kind of used for large power LED lamp flow type, described heat dissipation channel is rounded or polygonal.
Above-mentioned a kind of heat dissipation LED lamp with many light-emitting areas, the bottom of described radiator is provided with the link, the upper end that are connected with cap screw thread and is provided with the buckle end that is connected with the lampshade buckle.Snaps into position between locating ring limit and the lamp holder is established in the upper end of lampshade and radiator, has technique effect simply and easily is installed.
The above-mentioned high effect radiator of a kind of used for large power LED lamp flow type, described heat radiation page or leaf sheet free end are reversed into arc simultaneously forward or backwards along the axle center.Further increase heat radiation page or leaf sheet and increase the technique effect of the heat radiation of area of dissipation.
The above-mentioned high effect radiator of a kind of used for large power LED lamp flow type, described radiator be two symmetrical merging the branch radiator constitute, its merging face is on the wherein diagonal of radiator.Realize the technique effect of split assembling, and realize processing, simplify the difficulty of process heat dissipation channel with the heat radiation page or leaf sheet at radiator middle part.Divide radiator to merge buckle that can be through two ends or clench nail is fixed or viscose glue is fixed.Its merging face is on the wherein diagonal of radiator, realizes can not impacting the technique effect of Homogeneouslly-radiating.
