Abstract
The utility model discloses a structure improvement of a light-emitting diode (LED) lamp ceramic heat dissipating device, and relates to the field of ceramic heat dissipating devices, in particular to a heat dissipating structure of the LED lamp ceramic heat dissipating device. In the prior art, a ventilation channel of the ceramic heat dissipating device is not communicated totally, air convection is carried out inside a heat dissipating structure, and an LED lamp can not be cooled well. The structure improvement of the LED lamp ceramic heat dissipating device is characterized in that a substrate is provided with heat dissipating holes and contributes to ventilation, heat inside the LED lamp can be dissipated, and therefore the LED lamp can be cooled well.
Description
Technical field
The utility model relates to the ceramic heat sink field, relates to the radiator structure of LED lamp ceramic heat sink in particular.
Background technology
High temperature resistant, corrosion resistant characteristics that ceramic heat sink has, so the purposes scope of application of heat radiation is extensive, can be used in the conscientious heat radiation of fluid of various high temperature, high corrosion, good heat dissipation effect, on service life, ceramic heat sink is several times or tens times of metal heat sink under the square one.But the radiator structure of ceramic heat sink is a big factor that promotes radiating effect, so radiator structure decision radiating effect degree.
The current LED lamp that gains great popularity down, the quality of its radiating effect directly has influence on the service life of LED lamp, and the ceramic heat sink vent passages of the existing LED lamp of using always does not connect comprehensively, air is at the radiator structure internal convection, can better not be the cooling of LED lamp, influence the service life of LED lamp, thus ceramic heat sink to have what kind of radiator structure be the object that the researcher endeavours to research and develop.
Summary of the invention
The purpose of this utility model is to provide a kind of radiator structure can play the ceramic heat sink of better radiating effect.
For achieving the above object, the technical solution of the utility model is:
A kind of architecture advances of LED lamp ceramic heat sink comprises rounded pedestal and is formed on pedestal one lip-deep radiator structure, offers louvre on the pedestal.
Above-mentioned louvre is opened in the center of pedestal, above-mentioned radiator structure is for to extend upward the formation fin from louvre edge to susceptor edges on a surface of pedestal, this fin is furnished with a plurality of along louvre circumference average mark, form the sector channel that connects fully between each fin and the fin.
Between each fin and fin, also offer second louvre on the said base.
Also extend upward between each fin and fin on the said base and form second fin, second fin is divided into sector channel in the Y type passage of mutual perforation.
After adopting technique scheme, the beneficial effect of the architecture advances of a kind of LED lamp of the utility model ceramic heat sink is, compared with prior art, on pedestal, offered louvre more, the heat dissipation channel that connects fully in louvre and the radiator structure combines, help the circulation of air, the heat in the LED lamp is distributed, better be the cooling of LED lamp.
Description of drawings
Fig. 1 is the perspective view of the architecture advances of a kind of LED lamp of the utility model ceramic heat sink;
Fig. 2 is the perspective view of another angle of architecture advances of a kind of LED lamp of the utility model ceramic heat sink.
The specific embodiment
The specific embodiment below by the architecture advances of setting forth a kind of LED lamp of the utility model ceramic heat sink in conjunction with the accompanying drawings.
As Fig. 1, shown in Figure 2 is perspective view of the present utility model, comprise rounded pedestal 1 and be formed on pedestal 1 one lip-deep radiator structures 2, the screw hole 12 that offers lampshade hole clipping 11 in the position that keeps to the side and be used for locking on the pedestal 1 with miscellaneous part, be with part with the cloth of prior art, offer louvre 13 on the pedestal 1, this louvre 13 is opened in the center of pedestal 1, above-mentioned radiator structure 2 forms fin 21 for extending upward to pedestal 1 edge from louvre 13 edges on a surface of pedestal 1, this fin 21 is furnished with a plurality of along louvre 13 circumference average marks, form the sector channel 22 that connects fully between each fin 21 and the fin 21, for can being circulated, air can between each fin 21 and fin 21, offer second louvre 14 simultaneously, the louvre 13 and second louvre 14 help distributing of the interior heat of LED lamp, and the sector channel 22 that connects fully, air can be circulated in radiator structure, better be the cooling of LED lamp.
Radiator normally adopts the increase area of dissipation to realize better radiating effect, be similarly the radiating effect of realizing with good in the present embodiment, between each fin 21 and fin 21, also extend upward on the said base 1 and form second fin 23, second fin 23 is divided into sector channel 22 in the Y type passage of mutual perforation, also second louvre 14 is divided into two simultaneously, increasing by second fin 23 has also just increased the area of radiator structure 2 heat loss through conduction, and sector channel 22 is divided into the Y type passage of mutual perforation, air is circulated in radiator structure, the heat in the LED lamp is distributed.
The foregoing description and graphic and non-limiting product form of the present invention and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present invention to its suitable variation or modification of doing.
