The beneficial effect of LED of the present invention is：Its structure design is simple, good heat dissipation effect, advantageously ensures that production
Product use reliability, extend product service life, meet market use demand, be advantageous to product promotion.
Brief description of the drawings
Fig. 1 is the sectional view of LED of the present invention；
Fig. 2 is the rearview of the heat sink of LED of the present invention.
Embodiment
Preferred embodiment of the invention is described in further detail below.
As shown in Figure 1-2, in embodiment of the present invention, the LED, including LED chip 1, ceramics seat 2, outer cover 3, dissipate
LED core is fixed in hot plate 4, fin 5, insulation plate 6, substrate 7, through hole 8, electrode wires 9, mesopore 10, described one end of ceramics seat 2
Piece 1, the outside of the ceramics seat 2 socket heat sink 4 close to installation LED chip 1 one end, the heat distributed for absorbing LED chip 1,
Heat dispersion is improved, the edge cover of heat sink 4 buckles outer cover 3, in the cover of LED chip 1 is buckled in by outer cover 3, improves the peace of product
Full property and life-span, the downside of heat sink 4 are provided with insulation plate 6, improve the security of product, the insulation plate 6
Downside is provided with substrate 7, for fixing whole LED.
In the application, heat dispersion, the downside of heat sink 2 are provided with raised fin 5 in order to better improve.
The fin 5 is the structure extended laterally by middle part so that is formed between fin 5 and insulation plate 6
The heat dissipation channel to stretch out, further improve the thermal diffusivity of product.
The middle part of heat sink 4 is provided with mesopore 10, the inwall of mesopore 10 parcel ceramics seat 2.
In the application, product uses in order to better improve convenience, the middle part of ceramics seat 2 is provided with through hole 8, LED
The electrode wires 9 of chip 1 are stretched out by through hole 8.
Above content is to combine the further description that specific preferred embodiment is done to the present invention, is easy to the skill
The technical staff in art field is understood that and using the present invention, it is impossible to assert that the specific implementation of the present invention is confined to these explanations.
For general technical staff of the technical field of the invention, it can also make without departing from the inventive concept of the premise
Some simple deduction or replace, without by performing creative labour.Therefore, those skilled in the art's taking off according to the present invention
Show, the simple modifications made to the present invention all should be within protection scope of the present invention.
