Description
Technical field
The utility model relates to a kind of LED Down lamp radiator structure.
Background technology
Now, because the continuous development of LED lighting engineering, the performance of LED has had remarkable lifting; Its cost of manufacture is also more and more lower simultaneously; Therefore the LED lighting just possibly get in the average family, and the LED illumination is with a wide range of applications, no matter be commercialization or home lighting field.In the room lighting field, Down lamp is a kind of more light fixture that uses.Existing LED Down lamp generally all is to adopt great power LED as light source, and the great power LED luminous efficiency is high, and the lighting source brightness ratio that provides is higher.But, radiator structure is arranged so adopt great power LED all must possess as the LED light fixture of light source because the caloric value of great power LED own is also very high.Existing LED Down lamp generally all is the more radiating fin of design on the lamp tube, and the outer surface that these radiating fins generally all must be positioned at Down lamp just can play the effect of good heat radiating.The flange-cooled LED Down lamp that designs like this, one has influenced the good looking appearance of Down lamp, and two because Down lamp need adopt embedded mounting means, and its surperficial fin seems when mounted and relatively is in the way that the radiating effect of three this radiator structures is also poor.
The utility model content
To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of LED Down lamp radiator structure, and it has the advantage of good looking appearance, good heat dissipation effect.
To achieve these goals, the technical scheme that the utility model adopted is: the LED Down lamp comprises the lamp tube; It is characterized in that; The bottom of said lamp tube has substrate, and the inner surface of said substrate has the LED lamp plate, and the outer surface of said substrate has radiator; Also comprise said LED lamp plate and said radiator are fixed in a plurality of screw rods on the said substrate, said screw rod passes said LED lamp plate, substrate and radiator successively.
Preferably, said radiator has the housing of barrel mast shape, and said inner walls is extended has a plurality of fin.
Preferably, said fin circumference array is arranged in said enclosure interior.
Preferably, the radical length of said fin is less than the internal diameter of said housing.
Preferably, said housing bottom sidewall offers air admission hole.
The utility model is compared the advantage that is had with prior art: through substrate is set in the lamp tube; In the substrate both sides LED lamp plate and radiator are installed respectively; Through screw rod LED lamp plate, substrate and radiator are connected into an overall structure; Make heat on the LED lamp plate mainly by heat sink radiates, needn't design numerous exposed conveying appliance radiating fins on the lamp tube, can not have influence on the appearance looks elegant degree of Down lamp; Have only a laminar substrate between LED lamp plate and the radiator, heat-conducting medium seldom, heat-conducting effect is good, can fast the heat on the LED lamp plate be conducted on the radiator to distribute, so the LED Down lamp radiating effect of the utility model is very good.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the heat spreader structures sketch map of the utility model.
Among the figure: 10, lamp tube; 20, substrate; 30, LED lamp plate; 40, radiator;
50, screw rod; 41, housing; 42, fin; 43, air admission hole.
The specific embodiment
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.
Embodiment, see illustrated in figures 1 and 2: the utility model is a kind of LED Down lamp radiator structure, comprises lamp tube 10; It is characterized in that; The bottom of said lamp tube 10 has substrate 20, and the inner surface of said substrate 20 has LED lamp plate 30, and the outer surface of said substrate 20 has radiator 40; Comprise also said LED lamp plate 30 and said radiator 40 be fixed in a plurality of screw rods 50 on the said substrate 20 that said screw rod 50 passes said LED lamp plate 30, substrate 20 and radiator 40 successively.The utility model is through being provided with substrate 20 in lamp tube 10; LED lamp plate 30 and radiator 40 are installed respectively in substrate 20 both sides; Through screw rod 50 LED lamp plate 30, substrate 20 are connected into an overall structure with radiator 40; Heat on the LED lamp plate 30 is mainly distributed by radiator 40, needn't design numerous exposed conveying appliance radiating fins on the lamp tube 10, can not have influence on the appearance looks elegant degree of Down lamp; Have only a laminar substrate 20 between LED lamp plate 30 and the radiator 40, heat-conducting medium seldom, heat-conducting effect is good, can fast the heat on the LED lamp plate 30 be conducted on the radiator 40 to distribute, so the LED Down lamp radiating effect of the utility model is very good.
In order to promote the efficient of radiator 40 heat radiations, said radiator 40 has the housing 41 of barrel mast shape, and said housing 41 inwalls extend has a plurality of fin 42, and fin 42 is positioned at housing 41 inside, can accelerate the speed that heat distributes better; Do not have a negative impact each other in order to make between numerous heat radiations, said fin 42 circumference array are arranged in said housing 41 inside, make between the fin 42 spacing identical, and it is faster that heat distributes speed; The making of radiator 40 for ease, it is mobile that heat on the fin 42 can be risen automatically, and the radical length of said fin 42 makes in the radiator 40 and is formed centrally pore less than the internal diameter of said housing 41, can promote the heat radiating rate; Likewise, flow quickly in order to make the hot-air in the radiator 40, said housing 41 side walls offer air admission hole 43, are formed centrally the air current flow passage in air admission hole 43 and the radiator 40, also can accelerate the speed that heat distributes.
The LED Down lamp radiator structure of utility model, it has the advantage of good looking appearance, good heat dissipation effect.
