Abstract
The invention relates to a heat radiating device, in particular to a heat radiating device for a high-power LED street lamp, which comprises a plurality of mounting bases and a plurality of heat radiating fins, wherein the front surface of each mounting base is the mounting surface for each LED lamp, the heat radiating fins are fixed on the back surfaces of the mounting bases, the mounting bases are arranged at intervals, the heat radiating fins are in a multi-row structure, and the heat radiating fins are fixedly connected with the mounting bases to form the heat radiating device; the heat radiating device of the high-power LED lamp adopting the technical scheme not only can carry out heat conduction and heat radiation, but also can carry out heat convection, is reliable in heat radiation and has good heat radiation effect.
Description
Technical field
The present invention relates to a kind of heat abstractor, be specifically related to a kind of heat abstractor that is used for high-power LED street lamp.
Background technology
In today of country's call energy-saving and emission-reduction, carry out energy-saving and emission-reduction in the public utilities field and have very important exemplary role, the LED electricity saving of road lamp is outstanding, and colourity is good, non-maintaining, the life-span is long, is the optimal selection that substitutes conventional road lamp.Existing high-power LED street lamp mainly is made of lamp cap box and the LED light pearl that is arranged on the lamp cap box the inside, because power is bigger, the LED street lamp need increase heat abstractor, existing LED heat sink for lamp mainly is divided into two kinds, comprise passive heat radiation and active heat radiation, all there is certain defective in these two kinds of LED road lamp cooling modes: 1, passive heat radiation mainly is on the LED street lamp fin to be set, there is not hollow structure, not only accumulate dust and greasy dirt easily, and can only dispel the heat to the LED street lamp by heat conduction and heat radiation, but a large amount of LED lamp pearls all is sealed in the limited space of lamp cap box, a large amount of heat energy that a large amount of LED light pearl produces can't in time be dredged and get rid of by the heat exchange of fin and air, cause light source hot polymerization effect easily, cause that the LED junction temperature raises, and quickens the light decay of LED, influence operating efficiency efficient and the reliability of LED, and the LED lamp life-span is reduced; 2, in order to improve radiating efficiency, the large power road lamp that has has been taked active heat abstractor, by fan heat radiation, though the active radiating mode radiating effect of this kind is better, exists and takes up room greatly, and fan is fragile, the shortcoming of poor reliability.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of and not only can carry out heat conduction and heat radiation is dispelled the heat, and can carry out thermal convection current, heat radiation reliably, the good high-power LED heat sink for lamp of radiating effect.
In order to solve the problems of the technologies described above, the invention provides heat radiating device for high-power LED street lamp, include several mounting bases and some fin, the front of mounting base is the installed surface of LED lamp, be fixed with fin on the back side of mounting base, described several mounting bases are spaced, and described fin is many row's structures, and fin is fixedly connected with several mounting bases and constitutes a heat abstractor.
Adopt the heat radiating device for high-power LED street lamp of technique scheme to have following advantage: 1, to be installed on the mounting base owing to the LED lamp, and mounting base keeps at a certain distance away, fin combines a plurality of mounting bases, not only can realize common heat conduction and heat radiation heat radiation, and the space between fin with and mounting base between the formed passage in space can make air realize convection current up and down, improve radiating effect, can also prevent the accumulation of dust and greasy dirt simultaneously; 2, owing to taked the mode of passive heat radiation, remove the radiator fan of poor reliability, when improving radiating effect, also guaranteed the reliability of heat radiation.
Further, limit the scope of the spacing distance of mounting base, make heat radiation and volume all reach comparatively ideal situation, the spaced distance of described mounting base is 5～100mm.
Further, the mounting base spacing distance of selecting an optimum is convenient to industrial production as production standard, and the spaced distance of described mounting base is 15mm.
Further, limit the spacing distance of fin, make radiating effect and production cost reach an all more satisfactory situation, being spaced apart from being 5～100mm of described fin.
Further, the fin spacing distance of selecting an optimum is convenient to suitability for industrialized production as production standard, and the distance that is spaced of described fin is 13mm.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 be Fig. 1 A to structural representation.
The specific embodiment
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
As depicted in figs. 1 and 2, the invention provides a kind of heat radiating device for high-power LED street lamp, include five mounting bases 1 and some fin 2, the front of mounting base 1 is the installed surface of LED lamp, is fixed with fin on the back side of mounting base, and five mounting bases 1 are spaced, fin 2 is many row's structures, fin 2 is fixedly connected with five mounting bases 1 and constitutes a heat abstractor, and wherein the spacing distance of adjacent mounting base is 15mm, and the spacing distance of adjacent fin is 13mm.
Because the LED lamp is installed on the mounting base 1, and adjacent mounting base 1 at interval certain distance, the fin 2 of many row's structures has connected five all mounting bases 1, so not only can realize common heat conducting and radiating, and the space between the fin 2 with and mounting base 1 between the formed hollow structure in space can make air realize convection current up and down, improved radiating effect greatly.
The heat radiating device for high-power LED street lamp of embodiment 2 and embodiment 1 described structure are basic identical, and its distinctive points is: the spacing distance of adjacent mounting base is 5mm, and the spacing distance of adjacent fin is 100mm.
Embodiment 3
The heat radiating device for high-power LED street lamp of embodiment 3 and embodiment 1 described structure are basic identical, and its distinctive points is: the spacing distance of adjacent mounting base is 100mm, and the spacing distance of adjacent fin is 5mm
Above-described only is preferred implementation of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not influence effect of the invention process and practical applicability.
