The LED lamp is popular in recent years a kind of illuminating lamp, along with the LED(light emitting diode) technology develops rapidly, led light source is increasing in the ratio that illumination market occupies, the LED lighting engineering has shown outstanding energy-saving effect through for many years development and accumulation, and led light source is as a kind of emerging semiconductor light-emitting elements, it is little to have volume, the advantages such as energy consumption is low, and caloric value is low, and the life-span is long.Although LED belongs to cold light source, when work, still can produce a large amount of heats, serious decay appears in the at high temperature brightness meeting of LED lamp, scatter if heat is untimely, often temperature raises rapidly in the short time, causes brightness to decay fast, and then also can have a strong impact on light source life.
LED lamp of the prior art, in order to allow the heat fast spread, usually near LED illuminating circuit place the heat dissipation metal post is being set, and the outer circumferential walls at the heat dissipation metal post is provided with compact arranged heat dissipation metal fin, by having strengthened metallic area, utilize metal guide hot, so that heat is derived, reach the heat radiation purpose with this, but the common metal radiating fin all is structure as a whole with the heat dissipation metal post, can not dismantle, after long-term the use, the impurity such as dust can be piled up and cover on heat dissipation metal fin and the heat dissipation metal post, can have a strong impact on the heat conduction and heat radiation of heat dissipation metal fin and heat dissipation metal post, reduce radiating effect, and since heat dissipation metal fin and heat dissipation metal post be structure as a whole, can not dismantle, center on the heat dissipation metal post and the heat dissipation metal fin is close-packed arrays, so well clean metal radiating fin and heat dissipation metal post, radiating effect is relatively poor, and service life is short; The dismountable structure of being located on the thermal column of fin is also arranged at present, general all is end setting " worker " font piece that connects thermal column at fin, offer the groove that matches with " worker " font piece at thermal column, reach the dismounting purpose with this, simple in structure, but, employing " worker " font piece cooperates with groove, the wider width that needs " worker " font piece, when like this fin being installed, could be comparatively firm, the area that " worker " font piece of every fin like this occupies is just for larger, so in the limited circumference range of thermal column, the fin quantity that can install is few, and radiating effect is not ideal enough.
The utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of simple in structurely, easy to clean, long service life effectively guarantees the LED radiator structure of radiating effect.
For realizing above-mentioned technical problem, the solution that the utility model is taked is: the LED radiator structure, comprise thermal column and fin, staggered positive triangle groove and the inverted triangle groove of being provided with on the outer circumferential walls of described thermal column, described fin comprises the first fin and the second fin, described the first fin is provided with positive triangle convex at the link with thermal column, and the quantity of positive triangle groove is consistent on the quantity of described the first fin and the thermal column, described the second fin is provided with the inverted triangle projection at the link with thermal column, and the quantity of inverted triangle groove is consistent on the quantity of described the second fin and the thermal column, and described the first fin and the second fin be cooperating and inverted triangle projection and dismountable being inserted on the thermal column of cooperating of inverted triangle groove by positive triangle convex and positive triangle groove respectively.
Further be: described positive triangle and inverted triangle are acute triangle.
Further be: the positive triangle groove on the described thermal column and the equal up/down perforation thermal column of inverted triangle groove.
Further be: on the sheet leaf of described the first fin and the second fin by being equipped with a plurality of diffuser vanes on the inside direction of free end.
Further be: described the first fin free end is provided with a diffuser vane, and namely the free end of the first fin is " T " word shape, and described the second fin free end is provided with a diffuser vane, and namely the free end of the second fin is " T " word shape.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: above-mentioned LED radiator structure, described the first fin and the second fin are respectively cooperating and inverted triangle projection and dismountable being inserted on the thermal column of cooperating of inverted triangle groove by positive triangle convex and positive triangle groove, just can firmly be arranged in the groove by leg-of-mutton three-legged structure characteristic fin, and do not need to use wider width, and limit and the angle of positive triangle and inverted triangle can be agreed with mutually, such fin dismountable being located on the thermal column firmly, simple in structure, be convenient to the dismounting cleaning, and the quantity of fin still can be guaranteed, good heat dissipation effect; By being provided with a plurality of diffuser vanes on the inside direction of free end, can strengthen the area of dissipation of fin on the sheet leaf of described fin, further improve radiating effect, integral heat sink is effective.
