As further describing the aforementioned techniques scheme: aforesaid minor axis is located at the central authorities of disk sealed end, and the circular hole of minor axis and radiator is an interference fit.Minor axis and circular hole directly are connected in the mode that axle cooperates, not only firmly but also convenient.In addition, also can realize fixedlying connected of disk and radiator with another way, be specially: aforesaid disk minor axis is provided with external screw thread, and the radiator circular hole is provided with the internal thread that cooperates with disk minor axis external screw thread.With the mode that is threaded the two fixing, not only firm of disk and radiator of practising, disk and radiator are cooperated well, it is invisible also to make disk and radiator be connected rear thread, does not influence to put in order the attractive in appearance of lamp.
Aforesaid radiator is the integrated radiating sheet that the center is the scattering proterties with the circular hole.Fin adopts the material of aluminium matter or steel, and the integral structure of fin is convenient for production, and the attaching parts of having saved other connect.
Aforesaid aperture is horn-like, and reflector layer is layed in the inner wall surface of aperture.The inner wall surface that aperture is horn-like and aperture is laid the light that reflector layer sends LED can concentrate ejaculation, and make light can mistake to transmit to greatest extent.
As the further design again to the aforementioned techniques scheme: aforesaid substrate back is extended with the disk of one, and disk cooperates with disk to be fixed, and disk is provided with sunk screw, and the aperture correspondence is passed disk and substrate; The disk sealed end is provided with the screw with the sunk screw secure fit; Sunk screw is located in disk and the screw, does not see sunk screw from the surface of substrate.Sunk screw and screw all adopt concealed installation setting, when disk combines installation with substrate, do not see the connection that sunk screw is arranged fully from the outward appearance of whole base plate.
The aforesaid disk outside is provided with through hole, is provided with the sunk head rivet of fixed L ED wiring board in the through hole.Utilize simple sunk head rivet etc. just the LED wiring board to be fixed, directly simple.
In addition, the disk sealed end also is provided with the opening that can make lead be connected with the LED wiring board.Opening can make between LED wiring board and the LED power supply lead by and hide and whole lamp in.
Comprehensive above-mentioned design, LED lamp of the present utility model LED lamp compared to existing technology, the attaching parts such as having saved screw that are connected of the disk of high-powered LED lamp of the present utility model and radiator, utilize the design feature of oneself that disk and radiator are coupled together, its sunk screw also adopts concealed method that substrate and disk are fixed simultaneously, and it is attractive in appearance that the whole LED lamp is rich in.In addition, LED lamp part of the present utility model is less, is made up of 3-4 parts substantially, and is simple in structure, and the LED power supply also possesses good radiating condition, guaranteed that service life of LED power supply and LED's is normally luminous.
