Abstract
The utility model relates to an LED (light-emitting diode) curved-surface radiating structure. The LED curved-surface radiating structure comprises a cylindrical main radiator 1, wherein a plurality of curved-surface-shaped radiating fins 2 are distributed on the peripheral wall of the main radiator, and are distributed in a radial shape along the central axis of the main radiator; and each radiating fin 2 is an arc-shaped curved surface consisting of a plurality of small-arc-shaped curved surfaces. The LED curved-surface radiating structure has the advantages that the radiating area is enlarged, the radiating efficiency is increased, the requirement of an LED light source for radiation is guaranteed, and the service life is prolonged; and the LED curved-surface radiating structure can be widely applied in various LED lamps.
Description
Technical field
The utility model relates to LED heat radiation field, especially relates to a kind of LED curved surface radiator structure.
Background technology
Along with the LED Development of Packaging Technology, advantage obtains application more and more widely to great power LED because its light efficiency is high, and power is big, and volume is little etc.High-power LED illuminating lamp caloric value in use is bigger, usually corresponding heat abstractor need be set, to guarantee the normal use of LED illuminating lamp.How in the confined space, design enough efficiently radiates heat areas, become vital problem from the PN of LED thereby heat derived.At present, the LED heat spreader structures comprises that main radiator, main radiator outside are provided with strip fin (see figure 1), but its radiating effect in great power LED is not obvious.
The utility model content
The utility model technical problem to be solved provides a kind of LED curved surface radiator structure, overcomes the above-mentioned technical problem that exists in the prior art.
The utility model adopts following technical scheme:
A kind of LED curved surface radiator structure; Comprise columnar main radiator; Said main radiator periphery wall is distributed with polylith curved surface shape radiating fin, and said radiating fin radially distributes along the axis of main radiator, and every radiating fin is the arc-shaped surface of being made up of a plurality of little arc-shaped curved surfaces.
The arc opening direction of all radiating fins of the utility model is consistent.
The said radiating fin of the utility model is along main radiator circumferencial direction uniform array.
The extension starting point of all radiating fins of the utility model all is positioned on the same circumference.
The utility model is designed to curve form through the radiating fin on the main body periphery wall that will dispel the heat after adopting said structure, under traditional heat-dissipating structural volume same case, has increased area of dissipation greatly; Simultaneously because radiating fin is a uniform array, and extends starting point and all be positioned on the same circumference, guaranteed that the gas of up-down structure is unimpeded, and then improved radiating effect.The utility model radiating effect is desirable, and is simple in structure, can be through die casting or drawing process moulding, and select the conventional material aluminium for use, workable.
Description of drawings
The vertical view of the known LED curved surface of Fig. 1 radiator structure.
Fig. 2 is the vertical view of the utility model LED curved surface radiator structure;
Fig. 3 is the stereogram of the utility model LED curved surface radiator structure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
Like Fig. 2 and shown in Figure 3; A kind of LED curved surface of present embodiment radiator structure; Comprise main radiator 1, main radiator 1 is a cylindrical shape, and main radiator periphery wall is distributed with polylith curved surface shape radiating fin 2; Radiating fin 2 radially distributes along the axis of main radiator, and every radiating fin 2 is the arc-shaped surface of being made up of a plurality of little arc-shaped curved surfaces.Through the area of dissipation that arc-shaped surface increases radiating fin is set, and then increase the LED power that this LED radiator structure is suitable for.
Radiating fin 2 vertical main radiator horizontal planes in the present embodiment; And the extension starting point of all radiating fins is positioned on the same circumference; And uniform array is at main radiator 1 periphery wall, and the arc opening of all radiating fins 2 keeps same direction, effective like this area of dissipation that increased; Improve heat transmission, increase radiating effect.
More than LED curved surface radiator structure that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum; This description should not be construed as the restriction to the utility model, and all any changes of being made according to the utility model design philosophy are all within the protection domain of the utility model.
