Abstract
The utility model relates to a lighting source, in particular to an LED point light which is improved in cooling performance. A highly efficient and cooling LED point light comprises a light transmission shade, an LED lamp panel, an upper cover, a lower cover and a cable, wherein the upper surface of the upper cover is a cooling surface closed with a side surface, a through hole penetrated by a wire is arranged in the middle of the cooling surface, and the lower surface of the LED lamp panel is closely attached to the cooling surface in a fixing mode. The highly efficient and cooling LED point light is used for nightscape lighting.
Description
Technical field
The utility model relates to lighting source, relates in particular to a kind of LED spot light, particularly about the improvement of heat dispersion.
Background technology
Development along with electronics technology; LED (Light Emitting Diode) is because can efficiently be converted into luminous energy with electric energy; So be that the application of display screen, nightscape lighting is very extensive, become a kind of trend, the LED light structures of variety of way is developed and is come into operation.
The patent of one patent publication No. CN201496923U discloses a kind of water proof type can plug the LED spot light; Comprise a diffuser, which is provided with pcb board, a loam cake, a lower cover and the cable of a plurality of LED; This pcb board is installed on this and covers; This cable is arranged in this lower cover, and this loam cake and this lower cover removably connect by a locking part and between the two, be provided with a sealing ring, and diffuser covers last by the self-tapping screw locking; And be provided with in the lower cover and be convenient to the guide groove that cable passes, and in this guide groove, irritate and be provided with glue, cable is provided with female inserted terminal stroma, with lamp socket on public inserted terminal stroma plug.
So the weak point that above-mentioned patent scheme exists exists: the formation in the space of ccontaining power supply is through loam cake and lower cover locking formation, installs like this that some is unfavorable, and also there is certain shortcoming in water proofing property.
Therefore, the applicant proposes a kind of improvement project and puts it into commercial operation.Consult illustrated in figures 1 and 2ly, loam cake 1 is the integrative-structure that directly forms the following concave space of a ccontaining power supply, then fixed L ED lamp plate 2 and diffuser 3 successively.
No matter be above-mentioned patent scheme also or commercial improvement technical scheme; The identical weak point that all exists: the contact area of the upper surface of loam cake and fixed L ED lamp plate is very little; The heat dispersion of LED lamp plate is restricted, and is unfavorable for the permanent use of spot light.
The utility model content
Therefore, the utility model proposes a kind of improved technical scheme, can improve the thermal diffusivity of LED lamp plate in the spot light greatly, thereby prolongs the service life of spot light.
The technical scheme of the utility model is:
A kind of high-efficiency heat radiating LED spot light comprises diffuser, LED lamp plate, loam cake, lower cover and cable.Wherein, the upper surface of described loam cake be one with the radiating surface of side-closed, the centre of this radiating surface is provided with the through hole that runs through lead, the lower surface of described LED lamp plate is close on the radiating surface fixing.
Further, the peripheral distribution of described radiating surface has the complex root reference column, and the LED lamp plate is provided with corresponding with it locating hole, makes the lower surface of described LED lamp plate be close to the auxiliary fixing on the radiating surface by the cooperation of locating hole and reference column.
Further, the peripheral distribution of described radiating surface has a plurality of screws, and the LED lamp plate is provided with corresponding with it screw, makes the lower surface of described LED lamp plate be close to the secure fixation on the radiating surface through screws.
The utility model adopts as above technical scheme, with loam cake make into upper surface be one with the cover shape structure of the radiating surface of side-closed.Loam cake can be by aluminium matter pressing and forming, so the upper surface of loam cake (being radiating surface) has good thermal conductivity, can heat that be close to LED lamp plate fixing on the radiating surface be taken away rapidly.Therefore, the LED lamp plate of the LED spot light of the utility model and the upper surface of loam cake are to contact fixingly fully, and the heat dispersion of LED lamp plate has essence to improve, greatly the service life of spot light.

The specific embodiment
Combine the accompanying drawing and the specific embodiment that the utility model is further specified at present.
Consult Fig. 3 and shown in Figure 4, the high-efficiency heat radiating LED spot light of present embodiment comprises diffuser 3, LED lamp plate 2, loam cake 1, lower cover 4 and cable (not shown).The upper surface of described loam cake 1 be one with the radiating surface 11 of side-closed, the centre of this radiating surface 11 is provided with the through hole 112 that runs through lead, the lower surface of described LED lamp plate 2 is close on the radiating surface 11 fixing.Diffuser 3 is placed on the loam cake 1 fixing, and loam cake 1 is fastened on the lower cover 4 fixing.Loam cake 1 can be by aluminium matter pressing and forming, so the upper surface of loam cake 1 is that radiating surface 11 has good thermal conductivity, can heat that be close to LED lamp plate 2 fixing on the radiating surface 11 be taken away rapidly.
Preferably; The peripheral distribution of described radiating surface 11 has complex root reference column 111; LED lamp plate 2 is provided with corresponding with it locating hole 201, makes the lower surface of described LED lamp plate 2 be close to the auxiliary fixing on the radiating surface 11 by the cooperation of locating hole 201 and reference column 111.The peripheral distribution of described radiating surface 11 has a plurality of screws 113, and LED lamp plate 2 is provided with corresponding with it screw 202, makes the lower surface of described LED lamp plate 2 be close to the secure fixation on the radiating surface 11 through screws.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection domain of the utility model.
