Radiator 30 comprises a substrate 32, a plurality of radiating fin 34 and a hollow cylinder 36.Described substrate 32 comprises relative upper surface and lower surface, and upper surface is away from resettlement section 11.Substrate 32 adopts high heat conduction and electrically insulating material to make, as pottery etc.Preferably, described pottery is selected from aluminium oxide, aluminium nitride or the mixture of the two.The upper surface of substrate 32 is formed with a mounting groove 321 around described light emitting diode module 40, and this mounting groove 321 is used to install described lampshade 50.Also be formed with at least one through hole that runs through upper and lower surface 322 on the described substrate 32, so that light emitting diode module 40 is electrically connected with power supply module 20.
Radiating fin 34 and hollow cylinder 36 are arranged on the lower surface of substrate 32.These a plurality of radiating fins 34 are provided with around hollow cylinder 36, and all link to each other with hollow cylinder 36 outer surfaces.Hollow cylinder 36 is fixedlyed connected with the upper end of the insulation division 12 of resettlement section 11 away from an end of substrate 32.Power supply module 20 can be contained in the hollow cylinder 36, thereby reduces the volume of whole light fixture.In the present embodiment, described a plurality of radiating fins 34 and hollow cylinder 36 are one-body molded with substrate 32, and described a plurality of radiating fin 34, hollow cylinder 36 and substrate 32 adopt same material to make.
Lampshade 50 adopts transparent material to make, as glass, plastics etc.Lampshade 50 is positioned on the lamp socket 10 and is connected the common receiving space 60 that forms with lamp socket 10.Lampshade 50 comprise one with fixedly connected fixed part 52 of radiator 30 and the portion that is covered with 54 that is connected with fixed part 52.Fixed part 52, be covered with portion 54 and make by the method for injection mo(u)lding is separate respectively.The bottom of fixed part 52 is provided with an abutting end 523, and a plurality of lugs 524 are extended in the level bending on the abutting end 523.Abutting end 523 and lug 524 are arranged in the mounting groove 321 of radiator 30, and fixed form can be card and establishes, screw lock etc.In the present embodiment, abutting end 523 is circular, and lug 524 is four, and is symmetricly set on the bottom of abutting end 523.Be appreciated that ground, also can on abutting end 523, offer recess and make it be discontinuous plates, also visual real needs of the quantity of lug 524 and changing.On an end opposite of fixed part 52, be provided with one first location structure 521 with abutting end 523.First location structure 521 in the present embodiment is in the form of a ring a projection.
Be covered with portion 54 and roughly be the hemisphere shelly.The portion that is covered with 54 of lampshade 50 has incidence surface 542 and the exiting surface 543 that is oppositely arranged.Incidence surface 542 is positioned at the inboard of the portion of being covered with 54 and towards radiator 30, incidence surface 542 is handled by atomizing and formed some micro-structurals 70, and exiting surface 543 is positioned at the outside of the portion of being covered with 54 and directly contacts with the external world, and exiting surface 543 is smooth.Be covered with portion 54 and form one second location structure 541 with corresponding first location structure 521 in position that fixed part 52 engages.Second location structure 541 is in the form of a ring a groove in the present embodiment.Thereby first, second location structure 521,541 engaged can fixedly connected fixed part 52, be covered with portion 54.Certainly, first, second location structure 521,541 also can only play the effect of location, adopt then the ultrasonic fusion techniques with fixed part 52, be covered with portion 54 and link together.Through the fixed part 52 after the ultrasonic welding, be covered with the intensity that portion 54 can reach integrated lampshade 50.And lampshade 50 is divided into two, and adopt the method for injection mo(u)lding to make, compared to the lampshade of traditional blow molding, can improve the yield of lampshade 50, thereby save production cost.Because fixed part 52 can be adaptive with the difform portion 54 that is covered with, when assemble, finished product can increase more elasticity, can make the difform portion 54 that is covered with according to consumer demand, for example round table-like, American football shape etc., thereby the inventory risk of reduction lampshade 50.
Above-mentioned first, second location structure 521,541 is not limited to ring-type, also can be other alternative form such as the block-shaped protrusion that is disconnected from each other, block groove.It is projection that other first location structure 521 also is not limited to, and can be other structures such as groove for example; Second location structure 541 of Pei Heing also can be that projection waits other structures equally, with it.
Light emitting diode module 40 is positioned on the radiator 30 and is contained in receiving space 60.Light emitting diode module 40 is towards the incidence surface 542 of lampshade 50, and the light that light emitting diode module 40 is sent is injected lampshade 50 via the incidence surface 542 of lampshade 50, and final exiting surface 543 ejaculation lampshades 50 via lampshade 50.Because the incidence surface 542 of lampshade 50 has some micro-structurals 70, reduce the total reflection probability of light of the incidence surface of directive lampshade 50, improve the light extraction efficiency of whole light fixture, reduce light loss.
In the present embodiment, light emitting diode module 40 has five light emitting diodes.The quantity that is appreciated that the light emitting diode in the light emitting diode module 40 is not limited to present embodiment.Furthermore, light emitting diode module 40 is installed on the upper surface of substrate 32, is formed with circuit on this upper surface and is electrically connected with light emitting diode module 40.Preferably, this circuit is formed on this upper surface by electric plating method.
