Abstract
The utility model discloses a finned radiator for a high-power LED lamp and belongs to the technical field of LED lamps. The finned radiator mainly solves the problem that the heat dissipation structure of an existing radiator can not be applied to high-power lamps. The finned radiator is mainly characterized by comprising a heat dissipation platform which can be used for fixing a light source substrate; cooling fins are distributed in a radial shape along the periphery of the heat dissipation platform; the surface of each cooling fin is provided with an edgefold; one side of the heat dissipation platform is provided with a threaded hole used for being connected with the light source substrate, and the other side of the heat dissipation platform is provided with fixing teeth capable of being connected with an attachment on the periphery of the lamp. The finned radiator has the advantages of being simple in structure, easy to manufacture, convenient to assemble, excellent in heat dissipation effect and capable of being used in cooperation with the high-power LED lamp to prolong the service life of the LED lamp.
Description
Technical field
The utility model belongs to LED technical field of lamps, particularly a kind of high-power LED radiator.
Background technology
LED light source develops new type light source rapidly as a kind of extensive use, and with the old-fashioned encapsulating structure light source comparison that just starts to occur, volume is less, heat dispersion is more excellent, light extraction efficiency is higher.
At present, in industry, occurred doing radiator, mfg. moulding die one-shot forming by die casting aluminium, pottery, engineering plastics etc., be difficult to carry out machining, excellent radiator structure cannot be realized, and because the restriction of radiator structure can only be for small-power type light fixture, range of application is less.
The high-power LED lamp fin type class light fixture that is widely used in throwing light on, is widely used in industrial light, road lighting and room lighting etc., for dwindling light fixture volume, having the meaning of particular importance for light fixture.
Summary of the invention
Goal of the invention of the present utility model is to overcome the above-mentioned deficiency of prior art and the high-power LED radiator that a kind of radiating effect is good, cost is low, structure is simplified that provides.
The technical solution of the utility model is: a kind of large-power LED light fixture finned radiator, is characterized in that: comprise a cooling platform that can be used for fixed light source substrate; The outer fin distributing radially that is arranged with along this cooling platform; Described fin surface is provided with flanging; One side of described cooling platform is provided with the screwed hole for being connected with light source substrate, and opposite side is provided with the fixed teeth that can be connected with light fixture peripheral accessory.
Cooling platform described in the technical solution of the utility model is circular; Described fin distributes radially along the cylindrical of cooling platform; Described fixed teeth in the form of sheets, is connected respectively the inner side at fin.Radiator described in the technical solution of the utility model is cylinder-like structure.
Fin described in the technical solution of the utility model is 40 to 80.
The utility model is owing to adopting the radiator being comprised of cooling platform, fin, fixed teeth, wherein, fin distributes radially along the periphery of cooling platform, fin surface is provided with flanging, form fin formula fin, one side of cooling platform is provided with the screwed hole for being connected with light source substrate, the opposite side of cooling platform is provided with the fixed teeth that can be connected with light fixture peripheral accessory, thereby, making radiator is tubular structure, and between fin, form the heat dissipation channel of up/down perforation, greatly increased the contact area of radiator and air, be beneficial to scattering and disappearing of heat.The utility model is simple in structure, easy to manufacture, easy to assembly, and radiating effect is splendid, can be used in conjunction with high-powered LED lamp, extends the service life of LED lamp.The utility model is mainly used in high-power LED radiator.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is the structural representation of looking up of the present utility model.
In figure: 1, fin, 2, power outlet hole, 3, fixed teeth, 4, cooling platform.
The specific embodiment
As shown in Figure 1.Cooling platform 4 is circular, by the material that thermal diffusivity is good, is made.Cooling platform 4 one sides are provided with screwed hole, for being connected with light source substrate.In the middle of cooling platform 4 opposite sides, be provided with power outlet hole 2, inside circumference is provided with fixed teeth 3, can be connected with light fixture peripheral accessory.Fin 1 is 60, and every fin surface is equipped with flanging, forms the fin formula fin with flanging.Fin 1 distributes radially along the cylindrical welding of cooling platform 4, makes radiator form cylinder-like structure, and between fin 1, forms the heat dissipation channel of up/down perforation.Fixed teeth 3 in the form of sheets, is connected respectively the inner side at fin 1.
