Description
Technical field
The utility model relates to a kind of high-power LED street lamp radiator structure, and it belongs to LED lighting class.
Background technology
Along with the development of LED luminescent device, its cost progressively reduces, and application is more and more wideer, and the LED light fixture is very common at present in the application in street lamp field.Street lamp adopts the die casting structural member mostly as a kind of large-scale light fixture.The LED street lamp belongs to the large-power lamp class, and the principal element that influences its life-span is heat radiation.Accompanying drawing 1 has provided the typical normal form of existing LED road lamp cooling structure, and shown in accompanying drawing 1, the LED street lamp of prior art generally comprises structural member; Said structural member is provided with a LED mount pad, and said led light source body is seated on the mount pad, conducts the heat to structural member through mount pad and gets on; The structural member of said LED street lamp is a die-cast metal spare such as upper shell and lower house mostly, and volume is bigger; Certain thermal capacity is arranged, and this heat radiation to the led light source body has positive effect, but die-cast metal spare generally speaking thermal conductivity factor to be lower than fine copper or fine aluminium is much lower; For this reason, between led light source body and mount pad bigger thermal resistance will be arranged on the one hand, on the other hand; Accumulation of heat in the die casting structural member of LED street lamp arrives to a certain degree, and after thermograde diminishes, the temperature of the residing mount pad of led light source body position will maintain a higher level; Problem for bigger thermal resistance is arranged between led light source body and mount pad has the metal material that in mount pad, is embedded a high thermal conductivity coefficient in the prior art, solve such as pure copper material; But the accumulation of heat that this settling mode can not solve in the die casting structural member arrives to a certain degree; After thermograde diminished, the temperature maintenance of the residing mount pad of led light source body position was in the problem of a higher level, and obviously prior art has further improved necessity.
Summary of the invention
The purpose of the utility model is to provide a kind of high-power LED street lamp radiator structure, to overcome the problem that prior art exists.
A kind of high-power LED street lamp radiator structure that the utility model provides; Comprise the die-cast metal structural member; Said die-cast metal structural member is provided with mount pad; Said led light source body is seated on the mount pad, and inlay card has the high metallic object of thermal conductivity ratio die-cast metal structural member on the plane of said mount pad storing led light source body, it is characterized in that said metallic object comprises epitaxy part; Said epitaxy part is to extending away from the direction of mount pad, and the epitaxy part of said metallic object is fitted or inlay card on said die-cast metal structural member.
This a kind of high-power LED street lamp radiator structure of the utility model; Metallic object on the inlay card mount pad is provided with epitaxy part; Being arranged on the basis of possessing the advantage that less thermal resistance is arranged between led light source body and mount pad like this utilizes extension body thermal conductivity factor bigger, simultaneously to extending away from the mount pad direction; And fit or the such technical scheme of inlay card with the die-cast metal structural member; After having solved die-cast metal structural member thermal capacity and reaching to a certain degree, the temperature maintenance of the residing mount pad of led light source body position is in the problem of a higher level, test shows; Adopt the technical scheme of the utility model, the temperature of the led light source body installation surface on the mount pad is than more than low 1.4 degree of prior art.
As further improvement; The fitting area of locating portion of prolonging and die-cast metal structural member of said metallic object is more than three times of led light source body and mount pad contact area; The temperature of the led light source body installation surface on the mount pad has effect preferably than more than low 1.8 degree of prior art like this.
As further improving, it is more than five times of the arbitrary direction size of mount pad that the locating of said metallic object prolonged the distance of portion's distal-most end from the mount pad center, will further reduce the temperature of the led light source body installation surface on the mount pad like this.
As further improving, the not end of locating the portion of prolonging of said metallic object is provided with independently heat abstractor, can promote the thermal capacity of metallic object so on the one hand, also can further reduce the temperature of the led light source body installation surface on the mount pad.
