The specific embodiment
LED lamp radiator profile of the present utility model is the three-dimensional shape of right prism, have a plurality of sides, be positioned in the radiator inner space and all be evenly equipped with many radiating fins 2 on each side, these radiating fins 2 are along radiator length direction extension and isometric with radiator, and all radiating fins 2 surround an air vent 8 with radiator inside.The contrast accompanying drawing also elaborates to the utility model in conjunction with the embodiments below.
The utility model is made of one section hard heat conduction section bar, as shown in Figure 1, directly be processed into the straightedge column by mould, and inside has many radiating fins 2, these radiating fins 2 are an integral body with radiator, along radiator length direction extension and isometric with radiator, all radiating fins 2 are isolated into a plurality of little spaces with the radiator inner space, and the top of radiating fin surrounds an air vent 8 at the radiator center; In addition the radiator local array be provided with a plurality of installing holes 7, these installing holes 7 are positioned at radiator inside, extend along the incline of right prism, also are all an overall structure with radiator.When making light fixture, intercepting needs the shaped material of radiator of length to be assembled into light fixture then to get final product.
The utility model also can be put together by the identical thermal column 1 of a plurality of shapes, radiator shape after the amalgamation still is a right prism, in order to simplify mould structure and production technology, radiator should adopt the regular prism shape, thermal column 1 also is to be made of one section hard heat conduction section bar, produce by the mould one-shot forming, the thermal column that intercepts several certain-lengths carries out promptly forming radiator after the amalgamation.Each thermal column 1 has one or more sides of regular prism, and the LED lamp plate can both be installed in each side.On thermal column 1, all be provided with installing hole 7 and radiating fin 2, installing hole 7 and radiating fin 2 all extend along thermal column 1 length direction, and it is isometric with thermal column 1, installing hole 7 and radiating fin 2 all are arranged in the radiator in array, make radiator stressed equiblibrium mass distribution in each position after installation but installing hole 7 is set like this; And the set-up mode that radiating fin 2 uniform arrays are arranged can make radiator each several part heat suitable, and can form an air vent 8 in the radiator center, can make the heat balance of each side of radiator, helps improving radiating efficiency.
The shape of radiator can be multiple profiles such as positive pentagonal prism, positive six prisms, positive seven prisms or positive eight prisms, constitute directly by the Mold Making moulding by one section hard heat conduction section bar, also can be put together by several thermal columns 1 with the one or more sides of regular prism radiator.Shape and amalgamation thereof to radiator describes with reference to the accompanying drawings.With reference to Fig. 2 and Fig. 3, the positive pentagonal prism that is put together by five thermal columns 1, thermal column 1 has a side of regular prism, two ends have grab 5 and the draw-in groove 6 that can work in coordination, five thermal column 1 end to end formation array axis, the draw-in groove 6 that grab 5 on the thermal column 1 is adjacent on the thermal column 1 is engaged, as shown in Figure 3, and five thermal columns 1 composition radiator that links together; As shown in Figure 4 and Figure 5, positive six prisms that are put together by three thermal columns 1, thermal column 1 has two sides of regular prism, two ends have grab 5 and the draw-in groove 6 that can work in coordination, six thermal column 1 end to end formation array axis, the draw-in groove 6 that grab 5 on the thermal column 1 is adjacent on the thermal column 1 is engaged, as shown in Figure 5, and six thermal columns 1 composition radiator that links together; As shown in Figure 6 and Figure 7, positive seven prisms that are put together by two thermal columns 1, thermal column 1 has 3.5 side of regular prism, thermal column 1 is provided with fixing hole 9, two thermal columns 1 are positioned at symmetric position, by screw 10 and brace 11 two thermal columns 1 are connected and fixed, as shown in Figure 7, the radiator of two thermal column 1 be combined intos; As Fig. 8 and shown in Figure 9, positive eight prisms that are put together by two thermal columns 1, thermal column 1 has four sides of regular prism, two ends have grab 5 and the draw-in groove 6 that can work in coordination, two thermal column 1 end to end formation array axis, the draw-in groove 6 that grab 5 on the thermal column 1 is adjacent on the thermal column 1 is engaged, as shown in Figure 5, and two thermal columns 1 composition radiator that links together.
By above-mentioned splitting mode as can be known, a plurality of thermal columns 1 can form array axis when arranging, and the mode that engages that can adopt grab 5 and draw-in groove 6 to be complementary between the thermal column 1 is connected and fixed; And a plurality of thermal columns 1 be when can only form symmetry arrangement, can only adopt the fixing hole of establishing in addition 9 sheet 11 that is connected to be connected and fixed between the thermal column 1, and when fixing hole 9 during in thermal column 1 side, brace 11 also can be substituted by the LED lamp plate.Also may adopt when certainly, a plurality of thermal column 1 can form array axis and arranges and establish fixing hole 9 sheet 11 that is connected in addition and be connected and fixed.With reference to Figure 10, it is the enlarged diagram of above-mentioned engagement connection mode, the hook portion of grab 5 is positioned at the groove of draw-in groove 6 fully, both are engaged to be connected and fixed two thermal columns 1, but grab 5 and draw-in groove 6 be one-shot forming processing when mould is produced thermal column 1, and they are all along thermal column 1 length direction extension and isometric with thermal column 1.
With reference to Figure 11, two side external surfaces of every radiating fin 2 are provided with a plurality of evenly distributed heat radiation ribs 3, and between two adjacent heat radiation ribs 3, be provided with radiating groove 4, heat radiation rib 3 epireliefs and radiating groove 4 is recessed, and heat radiation rib 3 all is a semi-circular shape with the cross sectional shape of radiating groove 4, making that like this surface area of radiating fin 2 is bigger, also is that area of dissipation is bigger, and radiating effect is more remarkable.In order to simplify follow-up manufacturing process, heat radiation rib 3 and radiating groove 4 all extend and isometric with thermal column 1 along thermal column 1 length direction, promptly by mould with thermal column 1 one-shot forming.
More easy for the production and the assembling that make radiator, in order to make light fixture can satisfy the brightness requirement of illumination, in above-mentioned several splitting modes, best mode is two thermal columns and forms positive eight prismatic radiator schemes simultaneously.Two the thermal column shapes and the material of the utility model radiator are identical, therefore adopt same mould to make thermal column.Behind the thermal column by light fixture requirement intercepting certain-length, the LED lamp radiator that can piece together various different sizes all needs the mould of supporting correspondence, helps the batch process of LED light fixture, can also reduce the production cost of light fixture to a certain extent.
