Abstract
The utility model relates to a novel light-emitting diode (LED) heat dissipating section structure which comprises a rectangular or cylindrical LED space which is used for fixing an LED lamp, a main heat dissipating surface which surrounds the LED space, and lateral heat dissipating surfaces which are adjacent to the main heat dissipating surface. Heating dissipating ribs are usually arranged on the main heat dissipating surface and the lateral heat dissipating surfaces. A slope structure is arranged at the position where the lateral surfaces of the LED space and the bottom surface of the LED space intersects in an inwardly convex mode, the heat dissipating ribs are formed at the outer portion where the main heat dissipating surface and the lateral heat dissipating surfaces intersect, and the outer portion corresponds to the slope structure, and the curvature of a preset curve is the same as the curvature of an optical lens. The novel LED heat dissipating section structure is capable of greatly increasing overall heat dissipating area, and greatly enhancing heat dissipating effects.
Description
Technical field
The utility model relates to a kind of heat abstractor, has the New LED heat sink section bar structure of better radiating effect after espespecially a kind of improvement.
Background technology
Along with popularizing gradually of various high-powered LED lamps, the application of LED lamp is more and more extensive, but because LED etc. exist the shortcoming that caloric value can not in time shed, therefore in order to make these LED lamp normal operations, must the temperature of various auxiliary radiating devices when reducing LED work be set at the LED lamp, common way is that great power LED is welded with copper base or aluminium base first at present, then with the heat sink section bar of copper base or aluminium base and more cheap bulk normally aluminium section bar fix, reach the purpose of good heat radiation by larger area of dissipation, the radiating effect of aluminium section bar fundamentally is the total surface area that depends on heat-delivery surface, the total surface area of heat radiation is larger on the whole, the effect of heat radiation is also better, the size of heat radiation total surface area, normally determined together by the quantity of the length of radiating ribs and radiating ribs, radiating ribs is longer, more heat radiations of radiating ribs total surface area is just larger, be subjected to the restriction of volume, the length of radiating ribs can not be oversize, therefore, in the use of reality, the quantity that as far as possible increases often radiating ribs increases the total surface area of dispelling the heat, at present common heat-dissipation aluminum sectional material all is that main radiating surface and side radiating surface at aluminium section bar arranges radiating ribs usually, and at corner location place that main radiating surface and side radiating surface cross owing to exist the structure at right angle, heat-conducting effect is relatively poor so radiating ribs is not set usually, this has just caused the heat radiation total surface area by arranging to increase the heat radiation total surface area at the corner location place, not limited the performance of section bar radiating effect.
The utility model content
New LED heat sink section bar structure of the present utility model, comprise the rectangle that is used for fixed L ED lamp of setting/columniform LED space, surround the main radiating surface in this LED space and the side radiating surface adjacent with this main radiating surface, on main radiating surface and the side radiating surface radiating ribs is set usually, the side in the LED space in this New LED heat sink section bar structure and bottom surface intersection have inwardly protruded into ramp structure along predetermined curve, and the outside that the corresponding main radiating surface of this ramp structure and side radiating surface cross is formed with radiating ribs.
In New LED heat sink section bar structure of the present utility model, described predetermined curvature of a curve is identical with the curvature of optical lens.
In New LED heat sink section bar structure of the present utility model, the material of described heat sink section bar structure is metal.
In New LED heat sink section bar structure of the present utility model, the material of described heat sink section bar structure is red copper or bronze.
In New LED heat sink section bar structure of the present utility model, the material of described heat sink section bar structure is aluminium.
New LED heat sink section bar structure of the present utility model, owing between the bottom surface in LED space and side, be provided with suitable ramp structure, therefore increased thermal conductivity herein, and increased corresponding intensity, on this basis can be by the radiating ribs of some be set in main radiating surface and side radiating surface intersection, thereby greatly increased the heat radiation gross area, radiating effect is strengthened greatly, it is to be noted the ramp structure of establishing in bottom surface and the place, side in LED space, its radian can be common circular arc, also can determine by the radian of optical lens the size of fixed this gradient herein.
Relevant detailed content of the present utility model and technology just cooperate description of drawings as follows hereby.
Description of drawings
Fig. 1, be the cross section structure figure of New LED heat sink section bar structure of the present utility model;
Fig. 2, be the cross section structure figure of existing LED heat sink section bar structure.
The specific embodiment
Please refer to shown in Figure 1, cross-sectional view for a kind of preferred embodiment of New LED heat sink section bar structure of the present utility model, in the present embodiment, this New LED heat sink section bar structure 1 comprises the rectangle that is used for fixed L ED lamp of setting/columniform LED space, surround the main radiating surface 10 in this LED space and the side radiating surface 11 adjacent with this main radiating surface, on main radiating surface and the side radiating surface radiating ribs 15 is set usually, the side 13 in the LED space in this New LED heat sink section bar structure has inwardly protruded into ramp structure 18 with bottom surface 12 intersections along predetermined curve, the outside that the corresponding main radiating surface of this ramp structure and side radiating surface cross is formed with radiating ribs, further, described predetermined curvature of a curve is identical with the curvature of optical lens.
Further, the material of described heat sink section bar structure is metal, normally adopts the hot good metal of comparatively economic incisal guide, for example adopts red copper or bronze, and usually, the material of the heat sink section bar structure that adopts is comparatively cheap aluminium.
