In order to overcome the above problems; The utility model provides a kind of LED lamp with radiator structure; Comprise LED illuminator, transparent top cover, bottom, base, electric wire and electronic devices and components, said top cover is installed on the base front end, and said LED illuminator is installed between top cover and the base; Said base comprise be provided with the LED illuminator before recessed dish and be provided with the recurve dish of electronic devices and components; Recessed dish and recurve dish carry out capping by top cover and bottom respectively before said, said before recessed dish and the recurve dish is parallel to each other and dorsad, be provided with between recessed dish and the recurve dish before said with before recessed dish and recurve the dish radiating fin and the open tubular column that are connected; Said open tubular column correspondence and conducting are in the center of preceding recessed dish and recurve dish; Said radiating fin is that direction is two-way in length and breadth arranges, and said radiating fin and open tubular column have a distance and form " well " font passage in the periphery of open tubular column, and said base is integrated.
The said open tubular column outside is square cylindricality.
The radiating fin at said each place, zone is divided into radiating fin and the non-radiating fin that is right against open tubular column that is right against open tubular column; It is plate shaped and consistent with the distance of open tubular column that the said radiating fin that is right against open tubular column is, and the orthogonal said non-radiating fin that is right against open tubular column intersects the L shaped bending of formation in twos.
The described LED lamp of the utility model with radiator structure, through being provided with radiating fin, and radiating fin is connected in LED illuminator installation place and electronic devices and components installation place simultaneously; Not only satisfied the heat radiation of LED illuminator but also satisfied the heat radiation of electronic devices and components, the big and radiating fin of radiating fin area forms a circle, the radiating fin intercommunication all around of a said circle; Ventilation effect is good; Good effect is played in heat radiation, and radiating fin intercommunication all around, be convenient to clean; Can residual moisture and dirty, its long-term thermal diffusivity that uses is unaffected.In addition, the described LED lamp of the utility model, its base is formed in one, and radiating effect further improves, and simple in structure, and cost is lower.

The specific embodiment
Below in conjunction with accompanying drawing a kind of LED lamp with radiator structure of the utility model is described further.
As shown in Figure 1, the LED lamp with radiator structure of present embodiment comprises LED illuminator, transparent top cover 3, bottom 1, base 2, electric wire and electronic devices and components; Top cover 3 is installed on base 2 front ends, and the LED illuminator is installed between top cover 3 and the base 2, base 2 comprise be provided with the LED illuminator before recessed dish 22 and be provided with the recurve dish 21 of electronic devices and components; Before recessed dish 22 and recurve dish 21 carry out capping by top cover 3 and bottom 1 respectively, preceding recessed dish 22 and recurve dish 21 is parallel to each other and dorsad, be provided with between preceding recessed dish 22 and the recurve dish 21 with before recessed dish 22 and recurve dish 21 radiating fin 23 and the open tubular column 25 that are connected; Open tubular column 25 correspondences and conducting are in the center of preceding recessed dish 22 and recurve dish 21; Said radiating fin 23 is that direction is two-way in length and breadth arranges, and in the present embodiment, open tubular column 25 profiles are rectangular column; Certainly; Also can be transformed to other quadrangles, even polygon, as long as the demoulding can satisfy mold injection the time requires.In the present embodiment; The radiation areas that the four sides lateral wall 252 equal corresponding of open tubular column 25 is dispersed outwardly; The radiating fin 23 at each place, radiation areas is perpendicular to this area relative lateral wall 252; Radiating fin 23 has a distance and forms " well " font passage in the periphery of open tubular column 25 with open tubular column 25, and base 2 is integrated.The LED lamp with radiator structure of present embodiment, circle radiating fin 23 intercommunication all around, its ventilation effect is good; Further improved heat dispersion; And base can be realized one-body molded, through mold injection molding the time, along four sides lateral wall 252 directions of vertical open tubular column 25; The outside demoulding respectively promptly can realize the demoulding.
In the present embodiment, said open tubular column 25 outsides are square cylindricality.This design makes more symmetry of lamp body, and structure is firm, said before recessed dish 22 and recurve dish 21 be circle, can be that lamp body volume when usable floor area is constant is littler, also more attractive in appearance, structure is more firm.
In the present embodiment, said LED lamp also is provided with the fixed cap 4 of hollow toroid, and fixed cap 4 is provided with the screw thread that matches with base 2, and top cover 3 fastens for flat board and through fixed cap 4 and is installed on base 2 tops.Can certainly be transformed to top cover 3 and make for the transparent material of one, be installed on the base 2 through threaded engagement again, or be to be fixedly installed on the base 2 through screw with fixed cap 4.
In the present embodiment; Said radiating fin 23 is divided into the radiating fin 231 and the non-radiating fin 232 that is right against open tubular column that is right against open tubular column; The radiating fin 231 that is right against open tubular column is plate shaped and consistent with the distance of open tubular column, and the orthogonal said non-radiating fin 232 that is right against open tubular column intersects the L shaped bending of formation in twos.The non-radiating fin 232 that is right against open tubular column intersects the L shaped bending of formation with adjacent and the perpendicular non-radiating fin 232 that is right against open tubular column.Described radiating fin 232 intersects and forms L shaped bending, makes it have stronger fastness, can resist certain external impacts and is not damaged.In addition, also be provided with erection column on the radiating fin 23, said erection column is provided with the handgrip 8 that is rotationally connected with it, is easy to carry.
The utility model is not limited to above embodiment and conversion.
