The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.

The specific embodiment

Refer to 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 pedestal 10.

Pedestal 10 adopts highly heat-conductive material (as metal) to make, thereby can absorb the heat from LED source (not shown).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 along the barricade 13 extending 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 jointly surround one for accommodating the storage tank 14 of LED source.

In the present embodiment, the bearing of trend of barricade 13 is vertical with second surface 12, and understandably, the bearing of trend of barricade 13 and second surface 12 also can out of plumb, and barricade 13 is also not limited to the edge that is arranged on second surface 12, barricade 13 is also 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 first surface 11 and the second surface 12 of pedestal 10, it is for the LED source that is positioned at storage tank 14 inside is formed and is electrically connected to by electric wire with external power source, and can make a part of heat in storage tank 14 directly by through hole 15, be distributed in ambient air.

The edge, the left and right sides of the first surface 11 of pedestal 10 is respectively provided with some clamping parts 16, these some clamping parts 16 are for matching with the cover plate (not shown) of pedestal 10 belows, thereby LED source is enclosed in storage tank 14, to avoid LED source to suffer erosion, the damage of external environment, extend 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 and formed by some radiating fins space.In the present embodiment, along radiating fin group 20 on the width of pedestal 10, be arranged as three row, two row that are positioned at both sides are crisscross arranged and are formed by some the first radiating fins 21 and some the second radiating fin 22 spaces, and this two row is symmetrical arranged along the axis of the length direction of pedestal 10; Middle row is spaced and is formed by some the 3rd radiating fins 23, 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 the second radiating fin 22.The size of relative one end away from first surface 11 of the first radiating fin 21, the second radiating fin 22 and the 3rd radiating fin 23 is little compared with the size of one end of relatively close first surface 11, so can make heat can be too unconcentrated near first surface 11 places, equably by the dissipation of heat absorbing to ambient air.The cross section of the first radiating fin 21 and the 3rd radiating fin 23 is all roughly the strip that middle part is outwards circular-arc projection, so can make the cooling surface area of the first radiating fin 21 and the 3rd radiating fin 23 increase, and improves radiating efficiency; The cross section of the second radiating fin 22 is roughly rectangular.

Understandably, the shape of radiating fin group 20 is not limited to the situation of enumerating in the present embodiment, and it is other shapes such as prismatic or circle that its radiating fin also can be cross section, and its arrangement mode does not also limit, and visual actual conditions are adjusted.

Fixing arm 30 is for fixing LED lamp radiator 100 and lamp stand (not shown).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 is roughly L-type, and two fixed parts 32 of 32, two fixing arms 30 of a fixed part that the vertical support portion 31 that it comprises that first surface 11 from pedestal 10 extends and self-supporting portion 31 tops extend to form to one end of pedestal 10 are back to setting.The outer shape of support portion 31 is roughly cuboid, and it is highly 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 to having formed a groove 311 on support portion 31, when not affecting the support strength of support portion 31, alleviated the weight of LED lamp radiator 100.It is rectangular-shaped that fixed part 32 is roughly, and is formed with two fixing holes 321 that run through fixed part 32 upper and lower surfaces on it, and for fixing with lamp stand, fixing hole 321 can be screwed hole or through hole etc.

LED lamp radiator 100 by arranging a groove 311 on its fixing arm 30, when not affecting fixing arm 30 support strengths, alleviated the weight of LED lamp radiator 100, thereby make LED lamp radiator 100 more light, and saving material, cost-saving; And the flat structure of the some radiating fins in radiating fin group 20 has increased total area of dissipation of LED lamp radiator 100, 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 may 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.
