Description

A kind of semiconductor LED illumination lamp with radiator

Technical field

The utility model relates to a kind of illuminating lamp, especially a kind of semiconductor LED illumination lamp with radiator.

Background technology

At present, high-power and high-luminance semiconductor LED illumination lamp tool obtains use more and more widely, and the power circuit plate of Semiconductor light-emitting diode lamp inside radiating condition preferably just can reach the temperature stabilization state.The defective of existing heat radiation, heat insulating member is: the first, and area of dissipation is little, and volume is big, the cost height; The second, the preparation method of once-forming can't in the light of actual conditions change area of dissipation.

Summary of the invention

The purpose of this utility model provides a kind of semiconductor LED illumination lamp with radiator, and it has, and area of dissipation is big, and volume is little, the advantage that cost is low; And radiator forms by fin combination, and is for convenience detach, is easy to adjust area of dissipation, practical requirement.

In order to achieve the above object, the technical solution of the utility model is, a kind of semiconductor LED illumination lamp with radiator is provided, and comprises base, power circuit, and semiconductor light-emitting-diode, lampshade, radiator, characteristics are,

Described power circuit is fixed in the base.

Described semiconductor light-emitting-diode is arranged in the lampshade, and circuit connects power circuit.

Described radiator is arranged between base and the lampshade, and fixes with base and lampshade respectively.

Described radiator comprises fin, fin pad, fin connecting rod;

Described fin connecting rod is the pipe of hollow, and the connecting line of power circuit and semiconductor light-emitting-diode therefrom passes;

Through hole is set in the middle of described fin and the fin pad;

Several cooling fins and fin pad space overlay on the fin connecting rod, rivet into as a whole.

The semiconductor LED illumination lamp of above-mentioned band radiator, wherein, the internal diameter of the through hole on described fin and the fin pad and the external diameter of fin connecting rod are suitable.

The semiconductor LED illumination lamp of above-mentioned band radiator, wherein, there is projection at the edge that descends a slice most of described fin, fastens with base; There is projection at the edge of going up most a slice of described fin, fastens with lampshade.

Described fin pad is a small heat dissipating plate.

Described fin pad is the part of fin.

The semiconductor LED illumination lamp of the band radiator that the utility model provides, because radiator lumps together by a plurality of groups of fins, area of dissipation is big, has improved radiating efficiency; And little, the low cost of manufacture of radiator partial volume can be promoted the use of.

Fig. 2 is the ball bubble series structure schematic diagram of a kind of semiconductor LED illumination lamp with radiator of the utility model.

The specific embodiment

Following according to semiconductor LED illumination lamp shown in Figure 1 (belonging to shot-light series), specify better embodiment of the present utility model: semiconductor LED illumination lamp comprises base 10, power circuit 20, semiconductor light-emitting-diode 30, lampshade 50, radiator 40;

Power circuit 20 is fixed in the base 10.Semiconductor light-emitting-diode 30 is arranged in the lampshade 50, and circuit connects power circuit 20.Radiator 40 is arranged between base 10 and the lampshade 50, and fixing with base 10 and lampshade 50 respectively.

Radiator 40 comprises fin 41, fin pad 42, fin connecting rod 43; Fin connecting rod 43 is the pipe of hollow, and power circuit 20 therefrom passes with the connecting line of semiconductor light-emitting-diode 30; In the middle of fin 41 and the fin pad 42 through hole is set; Several cooling fins 41 overlays on the fin connecting rod 43 with fin pad 42 spaces, rivets into as a whole; The internal diameter of the through hole on fin 41 and the fin pad 42 and the external diameter of fin connecting rod 43 are suitable.There is projection at the edge that descends most a slice of fin 41, fastens with base 10; There is projection at the edge of going up most a slice of fin 41, fastens with lampshade 50.

In order further to increase area of dissipation, in the present embodiment, fin pad 42 is the part of fin 41, the once-forming manufacturing.

In order further to improve effect of heat insulation, in the present embodiment, between base 10 and radiator 40, increased a thermal insulation layer assembly.

Fig. 2 is another embodiment, belongs to the semiconductor LED illumination lamp of ball bubble series, and its characteristic parameter is identical with a last embodiment, and difference is: fin pad 42 is small heat dissipating plate.

In use, get final product according to common lighting use.Because the area of dissipation of this kind illuminating lamp is big, the radiator partial volume is little, and low cost of manufacture can be promoted the use of, and especially is fit to be applied in the illuminator of automobile, boats and ships, office buildings.

Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be conspicuous.Therefore, protection domain of the present utility model should be limited to the appended claims.
