Abstract
The utility model relates to the technical field of lighting, in particular to an LED lamp cooling device. The LED lamp cooling device comprises a metal cooling body and a plurality of groups of cooling fins. The metal cooling body and the cooling fins are integrally formed. The LED lamp cooling device is characterized in that the metal cooling body is a cylinder with a closed end, the cooling fins are arc-shaped bent pieces and are equidistantly arranged on the outer wall of the metal cooling body to form a tapered cooling body with big end up, and the upper end and the lower end of the tapered cooling body are of a fillet and a chamfer respectively. The cooling fins of special arc-shaped bent structures form the tapered cooling body with big end up, and natural convection is formed between the upper portion and the lower portion of the tapered cooling body, so that ventilating and cooling are facilitated, heat generated during lighting of an LED lamp can be quickly carried away, and cooling efficiency is high.
Description
Technical field
The utility model relates to lighting technical field, is specifically related to a kind of LED heat sink for lamp.
Background technology
Along with the continuous reinforcement of people's energy-conserving and environment-protective theory, solid state lighting industry also has the lighting source of the advantages such as environmental protection, energy-conservation, long service life in continuous exploitation.LED lighting engineering is utilized electroluminescence, and the advantage such as have that light efficiency is high, radiationless, the life-span is long is thought in the industry progressively to replace the third generation light source of conventional light source, but heat and high temperature that LED lamp produces while sending out, becomes the important bottleneck of restriction LED development.For solving the heat dissipation problem of LED lamp, there is on the market multiple heat abstractor, as Chinese invention patent application, (application number is: 201210006539.9) disclosed combined type LED radiator, comprise aluminum member bodies, member bodies has a base plate, and base plate periphery extends upward and forms a tapered hollow housing, and this hollow housing is a hollow cylinder with upper shed, hollow cylinder outside is attached with one-body molded, and is the multi-disc heat radiation thin slice that grid type is interspersed.Existing LED radiator not only complex structure, production cost is high, and still inadequate for its radiating effect of high-powered LED lamp.
Utility model content
For overcoming deficiency of the prior art, the utility model provides a kind of LED heat sink for lamp of simple in structure, perfect heat-dissipating, comprise heat dissipation metal matrix, with the integrated many group radiating fins of heat dissipation metal matrix, it is characterized in that: described heat dissipation metal matrix is the cylinder of one end sealing, radiating fin is arc fold bending part, and described radiating fin equidistant placement forms a up big and down small taper radiator on heat dissipation metal matrix outer wall and upper end and the bottom of taper radiator is formed with respectively fillet chamfering.
Further, the fillet chamfering that the junction of taper radiator end face and sidewall forms is 80-90 °.
Further, the fillet chamfering that the junction of taper radiator bottom surface and sidewall forms is 50-60 °.
Further, heat dissipation metal matrix adopting aluminium is made.
From above-mentioned to description of the present utility model, the LED heat sink for lamp that the utility model provides, radiating fin adopts unique arc fold bending structure, and many group radiating fins form taper radiator little under size, make taper radiator form between the upper and lower free convection, be conducive to circulation of air and heat radiation, the heat, the radiating efficiency that in the time of taking away rapidly the illumination of LED lamp, produce are high.
