Abstract
The utility model relates to the technical field of heat dissipation devices, in particular to a heat dissipation device for an LED spot lamp, comprising a cup-shaped heat dissipation body, wherein the outer side of the heat dissipation body is provided with a first heat dissipation fin group and a second heat dissipation fin group; the first heat dissipation fin group is formed by a plurality of first heat dissipation fins, and the first heat dissipation fin is in a circular radial shape; the second heat dissipation fin group is formed by a plurality of second heat dissipation fins, and the second heat dissipation fin is in an arch shape; and since the contact area of the radial shape first heat dissipation fin and the arch shape second heat dissipation fin with air is larger, i.e. the heat dissipation area is larger, the accumulated heat can be quickly dissipated with high heat dissipation efficiency, thereby, the utility model can quickly dissipate the heat generated during the LED working process when being installed in an LED spot lamp.
Description
Technical field:
The utility model relates to the heat abstractor technical field, relates in particular to a kind of heat abstractor of LED shot-light.
Background technology:
Because long service life, the energy consumption of LED (Light Emitting Diode, light emitting diode) are low, energy savings is remarkable, LED has been widely used in the daily life as light source, and as the LED shot-light, it is low in energy consumption, irradiation distance is far away, long service life.Yet along with the increase of LED quantity in the LED shot-light and high-power, high-brightness LED etc. are developed successively, the heat that is produced during the work of LED shot-light is just progressively upwards soaring.Therefore, the heat that how the LED shot-light is produced looses rapidly, becomes the significant problem that present LED shot-light technology must solve.
The radiator structure of existing LED shot-light, mainly the shell by the aluminium base that installs and fixes LED, aluminium alloy manufacturing constitutes, and aluminium base and shell utilize the heat conductivility of self, and the heat that produces when LED is worked is led away, but, because the volume of aluminium base is less, area of dissipation is little, causes radiating efficiency not high, and the shell of LED shot-light, because be subjected to the restriction of face shaping, its radiating effect is relatively poor, a large amount of heats that produce in the time of can not in time promptly LED being worked are led away.
The utility model content:
The purpose of this utility model is exactly the heat abstractor that the LED shot-light that a kind of area of dissipation is big, radiating efficiency is high is provided at the deficiency of prior art existence.
To achieve these goals, the technical solution adopted in the utility model is:
It comprises cup-shaped heat radiator body, the lateral surface of described heat radiator body forms the first radiating fin group and the second radiating fin group, the first radiating fin group is made of a plurality of first radiating fins, rounded radial of first radiating fin, the second radiating fin group is made of a plurality of second radiating fins, the curved shape of second radiating fin.
Described second radiating fin is made up of support portion, the radiating part that is connected the support portion outside, and support portion and radiating part are arc shape.
The outside of described radiating part is connected with the retainer plate of annular.
The radiating part of described second radiating fin is no less than two.
The bottom of described heat radiator body offers the inner fovea part that is used to place power pack, and the top of described heat radiator body offers the disposal area that is used to place aluminium base.
Described heat radiator body is provided with the through hole that inner fovea part can be communicated with the disposal area.
The bottom of described disposal area offers first screw that is used for fixing aluminium base.
The inwall of described inner fovea part is provided with second screw.
The utility model beneficial effect is:
The heat abstractor of a kind of LED shot-light that the utility model provides comprises cup-shaped heat radiator body, the lateral surface of described heat radiator body forms the first radiating fin group and the second radiating fin group, the first radiating fin group is made of a plurality of first radiating fins, rounded radial of first radiating fin, the second radiating fin group is made of a plurality of second radiating fins, the curved shape of second radiating fin, because second radiating fin of radial first radiating fin and curved shape and the contact area of air are bigger, be that area of dissipation is bigger, the heat of assembling promptly can be distributed the radiating efficiency height.Therefore, the utility model is installed in the LED shot-light, a large amount of heats that produce in the time of can in time promptly LED being worked are led away.
