Description

The led lamp radiator

Technical field

The present invention relates to a kind of radiator, relate in particular to a kind of radiator for the led lamp heat radiation.

Background technology

Now, (Light Emitting Diode LED) has been widely applied to a lot of fields to light emitting diode, especially is widely used in light fixture.Along with the power and the brightness of led lamp are increasing, the heat of its generation also increases day by day.Present industry is provided with a radiator usually in this light fixture be this light fixture heat radiation; Yet traditional radiator is generally all very heavy and area of dissipation is limited; Requiring at present under the environment that led lamp is light and radiating efficiency is high, this light fixture is difficult in the lighting field to be applied.

Summary of the invention

Given this, be necessary in fact to provide a kind of in light weight and led lamp radiator that area of dissipation is big.

The specific embodiment

See also Fig. 1 to Fig. 3, the led lamp radiator 100 that embodiment of the present invention provides comprises a pedestal 10, is located at radiating fin group 20 and two fixing arms 30 on the pedestal 10.

Pedestal 10 adopts highly heat-conductive material (like metal) to process, thereby can absorb from the LED source heat of (figure does not show).Pedestal 10 comprises a first surface 11 and a second surface 12 relative with first surface 11.

Second surface 12 edges of pedestal 10 are formed with the barricade 13 that extends along away from first surface 11 directions.Barricade 13 surrounds the ring-type of a sealing along the edge of second surface 12, thereby makes barricade 13 and second surface 12 surround a storage tank 14 that is used to accommodate LED source jointly.

In the present embodiment; The bearing of trend of barricade 13 is vertical with second surface 12, is appreciated that ground, but also out of plumb of the bearing of trend of barricade 13 and second surface 12; And barricade 13 also is not limited to be arranged on the edge of second surface 12, and barricade 13 also is not limited to surround the ring-type of sealing.

One end of pedestal 10 is provided with through hole 15; Through hole 15 runs through the first surface 11 and second surface 12 of pedestal 10; It is used for being electrically connected through electric wire formation with external power source being positioned at storage tank 14 inner LED sources, and a part of heats in the storage tank 14 directly are distributed in the ambient air through through hole 15.

The edge, the left and right sides of the first surface 11 of pedestal 10 respectively is provided with some clamping parts 16; These some clamping parts 16 are used for matching with the cover plate (figure does not show) of pedestal 10 belows; Thereby LED source is enclosed in the storage tank 14; To avoid LED source to suffer erosion, the damage of external environment, prolong the life-span of LED source.

Radiating fin group 20 is arranged on the first surface 11 of this pedestal 10 and extends upward, and radiating fin group 20 is arranged by some radiating fins space and formed.In present embodiment; Be arranged as triplex row along radiating fin group 20 on the width of pedestal 10; Two row that are positioned at both sides are crisscross arranged with some second radiating fins 22 spaces by some first radiating fins 21 and form, and the axis of these two capable length directions along pedestal 10 is symmetrical set; Middle row is spaced by some the 3rd radiating fins 23 and forms, and on the length direction of pedestal 10, each the 3rd radiating fin 23 is positioned in the middle of the first adjacent radiating fin 21 and second radiating fin 22.First radiating fin 21, second radiating fin 22 and the 3rd radiating fin 23 the size near an end of first surface 11 is little relatively away from the size of an end of first surface 11 relatively; So can make heat can be too unconcentrated, equably the heat that absorbs is distributed in the ambient air near first surface 11 places.The cross section of first radiating fin 21 and the 3rd radiating fin 23 all is roughly the strip that the middle part outwards is circular-arc convexity, and the cooling surface area of first radiating fin 21 and the 3rd radiating fin 23 is increased, and improves radiating efficiency; The cross section of second radiating fin 22 is roughly rectangular.

Be appreciated that ground, the situation that the shape of radiating fin group 20 is not limited to enumerate in the present embodiment, it is that prismatic or circle wait other shape that its radiating fin also can be cross section, and its arrangement mode does not limit yet, and visual actual conditions are adjusted.

Fixing arm 30 is used for led lamp radiator 100 fixing with lamp stand (figure does not show).Two fixing arms 30 are located at the two ends of pedestal 10, and are positioned at the two ends of radiating fin group 20, and its first surface 11 from pedestal 10 extends along the direction away from first surface 11.Fixing arm 30 roughly is the L type, and they two fixed parts 32 that comprise 32, two the fixing arms 30 of a fixed part that extend to form to an end of pedestal 10 from a vertical support portion 31 that the first surface of pedestal 10 11 extends and self-supporting portion 31 tops are back to setting.The outer shape of support portion 31 roughly is cuboid, and its height is greater than the height of radiating fin group 20, and its side direction sunken inside away from radiating fin group 20 forms a groove 311.Owing on support portion 31, formed a groove 311, in the support strength that does not influence support portion 31, alleviated the weight of led lamp radiator 100.It is rectangular-shaped that fixed part 32 roughly is, and is formed with two fixing holes 321 that run through fixed part 32 upper and lower surfaces on it, fixes with lamp stand being used for, and fixing hole 321 can be screwed hole or through hole etc.

Led lamp radiator 100 is through being provided with a groove 311 on its fixing arm 30; When not influencing fixing arm 30 support strengths; Alleviated the weight of led lamp radiator 100; Thereby make led lamp radiator 100 more light, and save material, practice thrift cost; And the flat structure of the some radiating fins in the radiating fin group 20 has increased total area of dissipation of led lamp radiator 100, has improved the radiating efficiency of led lamp radiator 100.

Technology contents of the present invention and technical characterstic disclose as above, yet those skilled in the art still maybe be based on teaching of the present invention and announcements and made all replacement and modifications that does not deviate from spirit of the present invention.Therefore, protection scope of the present invention should be not limited to the content that embodiment discloses, and should comprise various do not deviate from replacement of the present invention and modifications, and is contained by appended claim.
