The specific embodiment
The specific embodiment one
The LED shot-light that this specific embodiment provides comprises as shown in Figure 1: lamp socket 1, led chip 2, lens 4, cover plate 5, heat radiation Lamp cup 6 and heat conducting disk 7.Wherein lamp socket 1, led chip 2 and lens 3 are the outsourcing standard component.
Lamp socket 1 in this specific embodiment is common screw lamp holder, has two to be used for the electrode that is electrically connected with the city on it, and this two electrode is electrically connected with led chip 2, is led chip 2 power supplies.Comprise plurality of LEDs lamp 3 on the led chip 2, and every LED lamp 3 corresponding lens 4.LED shot-light foremost is covered with a cover plate 5, and the position of corresponding lens 4 offers loophole 51 on the cover plate 5.Heat conducting disk 7 is in the form of annular discs, comprises trying to get to the heart of a matter and the rim.Led chip 2 is close in trying to get to the heart of a matter of heat conducting disk 7.The heat that produces during led chip 2 work is transmitted to heat conducting disk 7, and gives heat radiation Lamp cup 6 by heat conducting disk 7 conduction, is distributed by heat radiation Lamp cup 6.Heat radiation Lamp cup 6 is made of multi-disc fin 60, have bigger area of dissipation, and made by heat conduction good metal thin plates such as aluminium or copper, thereby radiating effect is good.
Fin 60 in this specific embodiment, its structure comprises on it as shown in Figure 2: fitting part 61, Access Division 62 and four connecting portions 63.Wherein fitting part 61 is the close-fitting breach of a strip, and it is used for fin is connected with heat conducting disk 7.Assembling back fin 60 is with on this close-fitting breach rim that is stuck in heat conducting disk 7 tightly.Because cooperating between fin 60 and the heat conducting disk is tight fit, so heat-conducting effect is good.
As shown in Figure 4, each connecting portion 63 comprises breach 64 and the insertion section 65 that is used to insert adjacent fin 60 breach.During overlap joint, breach 64 on every fin 60 is inserted by the insertion section 65 of adjacent fin 60 correspondences of one side, insertion section 65 is overlapped fixing by bending after inserting, the adjacent breach 64 of its opposite side is inserted in 65 of corresponding its insertion sections, and bending and overlap fixingly, so two fin, 60 overlap joints that are adjacent of fin 60 are fixing.Some fin 60 head and the tail connect, and then can constitute heat radiation cup 6 shown in Figure 3.Insertion section 65 can be the bigger insertion sheet of a slice as shown in Figure 4, also can be divided into two less insertion sheets as shown in Figure 5, also can be divided into more than three even three as required certainly.The shape of breach 64 and size and insertion sheet are suitable, such as being square, semicircle etc., also can be other shapes such as shape as shown in Figure 5.The number of connecting portion 63 can need to be provided with as the case may be, in general with three or four for well.Every fin 60 is provided with four connecting portions 63 in this specific embodiment.
Lamp socket 1 is made for plastic material, non-scald on hand in the time of can guaranteeing this product is installed.Heat radiation Lamp cup 6 is overlapped mutually by tens fin 60 and forms, and compares the aluminium matter heat radiation Lamp cup that existing die casting mode is made, and area of dissipation increases greatly, and the airflow smooth in the gap between the fin 60, so radiating effect is obviously better.In addition, fin 60 can be accomplished very thin, so the weight of entire heat dissipation Lamp cup 6 generally has only about 1/3rd of existing die-cast product, has saved raw material greatly, has reduced material cost.The whole LED shot-light shows attractive in appearance lightly, outward.Fin 60 adopts highly heat-conductive materials by being stamped to form, good heat dissipation effect, production efficiency height, but anode handle and obtain multiple gay colours, it itself is exactly an art work that profile attractive in appearance makes.And the anode processing can not influence radiating effect.The LED lamp life-span is long and energy-efficient, power consumption ordinary incandescent lamp 1/3 to 1/10 between, and do not have ultraviolet ray and infrared ray in the spectrum of LED lamp, be typical green illumination light source.Not mercurous and other nuisance of product all material can reclaim fully.
The specific embodiment two
The heat radiation Lamp cup 6 of this specific embodiment as shown in Figure 6, fin 60 by seven annulars is formed by stacking, be symmetrically distributed with two connecting portions 63 on the annulus inner ring of every fin 60, identical with the principle of the specific embodiment one, connecting portion 63 comprises breach 64 and insertion section 65.Corresponding breach 64 on its adjacent fin 60 in top is inserted in the insertion section 65 of every fin 60, and bending and overlap fixingly then makes to keep certain interval and fixing between the fin 60, and the concrete structure of connecting portion 63 is referring to Fig. 5.And entire heat dissipation Lamp cup 6 tight fits are enclosed within heat conducting disk 7 peripheries.The heat conducting disk 7 of this specific embodiment is deep comparatively speaking, roughly be one cup-shaped, but its effect is identical with principle with the specific embodiment one, and its bottom also is to be close to led chip 2, and is used to fall the heat that led chip 2 produces and conducts to heat radiation Lamp cup 6.For unification, this place also is called heat conducting disk 7.This specific embodiment is compared the specific embodiment one, and is simple in structure, easy to assembly, is particularly suitable for the LED shot-light of single lamp.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
