Description
Technical field
The utility model is related to the spherical LED lamp radiators that LED lamp heat sink more particularly to a kind of multidimensional radiate.
Background technology
As incandescent lamp is gradually backed out the arena of history, people are more and more urgent for the demand of new type light source, and LED light by
In its high life, high response speed, it is environmentally protective the advantages that be increasingly valued by the people.LED is working as temperature-sensitive element
The heat as fruit chip generates cannot effectively shed in the process, the junction temperature for leading to PN junction be increased, and then seriously affect its work
Performance.The heat dissipation of LED light have become influence its performance and restrict its development key factor, be current research hot spot and
One of difficult point.
In recent years to LED heat dissipation generally use parallel fins construction, also someone it is transformed, such as on fin
Newly crack gap or the corresponding grid of setting in face, and the optimization in flow field is realized with this, enhances thermal convection current, improves its heat dissipation performance.
Current techniques have the following problems and defect：1st, existing parallel fins are due to its form limitation, to wandering
Hot stage effectiveness is general；2nd, current radiators are usually designed around appearance, have ignored the optimization of internal conductive structure and micro-
See the analysis of flow mechanism.
Utility model content
For defect in the prior art or deficiency, technical problem to be solved in the utility model is：There is provided one
The spherical LED lamp radiator of kind multidimensional heat dissipation, that takes into account interior microscopic flowing, the heat dissipating method based on free convection can have
Effect improves the heat dissipation performance of high-powered LED lamp.
To achieve these goals, the technical solution that the utility model is taken is to provide a kind of spherical LED of multidimensional heat dissipation
Lamp radiator, the barrel-shaped radiator which divulges information for hollow one end, vertically sets in the outside wall surface of the radiator
There are several heat dissipation forks, heat dissipation fork is overhanging, and is decomposed into two pillars, and vent rib, the radiator are set on each pillar
Bottom is provided with the heat emission hole that cold air is facilitated to enter.
As further improvement of the utility model, the heat emission hole is 2-4.
It is V-arrangement between the heat dissipation fork as further improvement of the utility model.
As further improvement of the utility model, the vent rib on the pillar is two, in F types.
As further improvement of the utility model, the lumen of radiator bottom is equipped with LED chip.
The beneficial effects of the utility model are：The utility model compares the advantage of prior art：1. heat dissipation fork and cooling fin
Item can increase heat dissipation area, realize multidimensional heat dissipation, improve radiating efficiency；2. can be directly used for spherical LED lamp, collect practicability
With thermal diffusivity in one；3. compared to the LED light better economy of active heat removal form.

Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the rearview of the utility model；
Fig. 3 is the side view of the utility model；
Wherein digital representation：1st, heat dissipation fork；2nd, pillar；3rd, vent rib；4th, heat emission hole.
Specific embodiment
Explanation and specific embodiment further illustrate the utility model below in conjunction with the accompanying drawings.
As shown in Figures 1 to 3, the utility model provides a kind of spherical LED lamp radiator of multidimensional heat dissipation, LED light heat dissipation
The barrel-shaped radiator that device is divulged information for hollow one end is vertically equipped with several heat dissipation forks 1, the heat dissipation in the outside wall surface of the radiator
Pitch 1 overhanging, and be decomposed into two pillars 2, vent rib 3 is set on each pillar 2, the radiator bottom be provided with facilitate it is cold
The heat emission hole 4 that air enters.
The heat emission hole 4 is 2-4.
As shown in Figures 1 to 3, it is V-arrangement between the heat dissipation fork 1.
Vent rib 3 on the pillar 2 is two, in F types.
The lumen of radiator bottom is equipped with LED chip.
The above content is combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, several simple deduction or replace can also be made, should all be regarded
To belong to the scope of protection of the utility model.
