Detailed description of the invention

In order to more clearly state the utility model, below in conjunction with accompanying drawing, the utility model is further described.

Refer to Fig. 1, the dichotomous radiator structure of the LED lamp that the utility model provides, comprise lamp plate 10 and the inner thermal column 11 in hollow structure, thermal column 11 is formed by integrated aluminium limit turnup, this thermal column 11 is fixed on both after in lamp body 12 and encloses a container cavity, and driving power 13 is fixed in this container cavity; The top of thermal column 11 forms multiple equally distributed staggered form fin 111 after the outside flanging in periphery of this thermal column 11, a back-up ring 112 is enclosed between multiple fin 111, lamp plate 10 to be placed on this back-up ring 112 and to be electrically connected with driving power 13, and this lamp plate 10 is placed in after on back-up ring 112, container cavity forms a heat dissipation channel.The back-up ring utilizing fin to be formed in this structure, to lay lamp plate, not only increases the contact area of lamp plate and thermal column, strengthens the stability of structure between the two; And increase area of dissipation, make radiating effect better.

Compared to the situation of prior art, the dichotomous radiator structure of the LED lamp that the utility model provides, directly formed the thermal column 11 of hollow structure inside by integrated aluminium limit turnup, and the top of this thermal column 11 forms multiple equally distributed staggered form fin 111 after the outside flanging in periphery of this thermal column; The design of this flanging and bead structure, not only increases area of dissipation, improve radiating effect, and utilizes the hollow structure of thermal column to install driving power, Appropriate application space; Meanwhile, adopt aluminium limit turnup, not only save material, and aluminium limit have certain elasticity more easily and miscellaneous part fit, strengthen the stability of structure.The features such as the utility model has that reasonable in design, area of dissipation is large, good heat dissipation effect, saving material and Appropriate application space.

In the present embodiment, often form a trigonometric expression between adjacent two fin 111 and intersect passage of heat 113, the heat produced when lamp plate 10 works with driving power 13 is intersected passage of heat 113 conducted by this.The surface of thermal column 11 evenly offers multiple thermal vias 115 communicated with hollow structure, the heat produced when lamp plate 10 and driving power 13 work is shed by each thermal vias 115.The shape of each intersection passage of heat is equilateral triangle formula, because the shape size of each fin 111 is identical, therefore, the intersection passage of heat formed is equilateral triangle formula, and non-acute angle equilateral triangle, certainly, can also be the equilateral equilateral triangle in obtuse angle, can improve the shape of fin according to the actual needs.Because lamp plate and driving power are all operationally produce heat, and lamp plate is placed on back-up ring, therefore the heat that the part that lamp plate is placed in back-up ring operationally produces is conducted by intersection passage of heat 113, and the heat of driving power 13 in container cavity sheds by thermal vias 115, the heat between both and the air of outside carry out intersection heat conduction by this intersection passage of heat 113.

In the present embodiment, the inwall of thermal column 11 is the transition of inner circle arcuation, and the two crimping ends on aluminium limit form the jointing edge of this thermal column 11, and the gap of this jointing edge forms a heat radiation gap 114.The design in heat radiation gap 114, increases area of dissipation further; Because inside is the transition of inner circle arcuation, therefore the structure of whole light fixture is more reliable and more stable.Lamp body 12 is made up of heat radiation plastics, certainly, makes material and does not limit to, as long as be made up of heat radiation material.Radiator structure of the present utility model can be used in various dissimilar light fixture.

Be only several specific embodiment of the present utility model above, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
