The specific embodiment
Please refer to Fig. 2 to Fig. 5, an a kind of preferred embodiment of radiator,
Described a kind of radiator, it comprises the heat radiator body 100 of a strip, described heat radiator body 100 have one positive and one and the front opposing to the back side, the back side of described heat radiator body 100 is a plane.The back side of described heat radiator body is a plane, and this heat radiator body is simple in structure, and is not provided with radiating fin, greatly reduces the die sinking expense, shortens production technology, enhances productivity.In the present embodiment, described heat radiator body 100 offers three the first screws that are used for locking screw, and described the first screw runs through the positive back side of heat radiator body 100.
In the present embodiment, two sides are respectively equipped with a flanging 110 about the described heat radiator body 100, and described flanging 110 extends along heat radiator body 100 directions.Two sides are respectively equipped with flanging about the heat radiator body, and lamp plate directly is positioned between heat radiator body and two flangings, and it is spacing that two flangings play left and right directions to lamp plate, simple in structure.In the present embodiment, the described flanging 110 convex fronts that are located at described heat radiator body 100.
In the present embodiment, rear two sides are respectively equipped with a support chip 120 before the described heat radiator body 100.Two sides are respectively equipped with a support chip after before the heat radiator body so that this heat radiator body and lamp holder, when lampshade assembles, this support chip can will leave the space between heat radiator body and lamp holder, the lampshade, radiating effect is better.
In the present embodiment, described support chip 120 is convexly equipped with the back side in described heat radiator body 100 downwards.
In the present embodiment, described support chip 120 offers one for the second screw 121 that locks screw.
In the present embodiment, two sides of described support chip 120 and the junction of heat radiator body 100 are respectively equipped with a release groove 130.
As shown in Figure 2, be the installation diagram of this radiator and lamp plate 200, lamp plate 200 is provided with three the 3rd screws 210.During assembling, the back side of lamp plate 200 directly is positioned over the front of heat radiator body 100, and the first screw and the 3rd screw be for corresponding one by one, and lamp plate 200 and heat radiator body be fixed together in the first screw and the 3rd screw by three screw lockings.
