Description
Technical field
A kind of LED lamp structure is the utility model is related to, more particularly to a kind of radiator structure of LED.
Background technology
Existing heat dissipation structure of LED lamp includes heat dissipation metal cup and the covered plastics layer being coated on the outside of heat dissipation metal cup mostly
Lamp body shell, by the inside punching press of jatharapanvartanasana side wall of heat dissipation metal cup, form an annular step surface, then by LED light source board
The step surface is installed on by taking, realizes fixed and radiating.Due to the groove that the surface of heat dissipation metal cup sets to the concave and formed, make
Obtain lamp body shell and be vertically followed successively by thin-thick-thin structure, when shrink effect occurs for the lamp body shell, due to answering
Power is uneven, and the thicker part of lamp body side wall of outer shell, which is shunk, exceedes relatively thin part, and then forms an annular sunk structure.
The outward appearance of product is greatly affected, the yields of commodity is affected.
Utility model content
The purpose of this utility model is the deficiency for overcoming prior art, there is provided a kind of radiator structure of LED, solves
The problem of lamp body shell shrinks, greatly improves the overall appearance of product, improves product yield, while ensure heat dispersion.
Technical scheme is used by the utility model solves its technical problem：
A kind of radiator structure of LED, including heat dissipation metal cup and LED light source board, the outer injection of the heat dissipation metal cup
It is formed with lamp body shell；The heat dissipation metal cup has jatharapanvartanasana side wall, and the jatharapanvartanasana side wall inwardly convexes into a plurality of positioning
Boss, the cooperation plane of the upper surface composition interruption of a plurality of positioning boss；The LED light source board is mutually leaned on the cooperation plane
Connect, and form conductive structure.
As a preferred embodiment, the positioning boss is uniformly distributed circumferentially, its quantity is 8~30.
As a preferred embodiment, the quantity of the positioning boss is 10,11 or 12.
As a preferred embodiment, the upper surface of the positioning boss is fan shape, and the upper surface of a plurality of positioning boss
The cooperation plane of composition is the annular shape of interruption；Center of circle angular region corresponding to the positioning boss is 15 °~36 °.
As a preferred embodiment, the width of the positioning boss is thick 1.5 times~8 times of heat dissipation metal wall of cup.
As a preferred embodiment, the wall thickness range of the heat dissipation metal cup is 0.1mm~0.5mm.
The beneficial effects of the utility model are：Optimize the structure of heat dissipation metal cup, and then change injection molded in the gold
Belong to the shape of the lamp body shell on heat radiating cup surface.The step surface of heat dissipation metal cup surface punching press is changed into a plurality of interruptions to set
Positioning boss, its size and quantity pass through optimization design, after the injection molded lamp body shell of heat dissipation metal cup surface, outside lamp body
Shell is correspondingly formed a plurality of boss.When shrinking deformation occurs for the lamp body shell, the larger part surrounding of wall thickness is and wall thickness
Relatively thin part is adjacent, and each stress is balanced, will not produce the situation of a Direction distortion thereto, greatly improve product
Overall appearance, improve product yield.Simultaneously because the size and quantity of boss calculate by optimization, ensure heat dispersion.
The utility model is described in further detail below in conjunction with drawings and Examples；But one kind of the present utility model
The radiator structure of LED is not limited to embodiment.
Brief description of the drawings
Fig. 1 is exploded perspective view of the present utility model；
Fig. 2 is cross-sectional view of the present utility model；
Fig. 3 is top view of the present utility model.
Embodiment
Embodiment：
Include LED light source board 2 referring to a kind of LED product that shown in Fig. 1 to Fig. 2, the utility model is applied, metal dissipates
Hot cup 1, lamp body shell 3, lampshade 4, driving plate 6 and lamp holder 5.The LED light source board 2 connects fixation with the heat dissipation metal cup 1,
And radiated by heat dissipation metal cup 1.The driving plate 6 is installed on inside the heat dissipation metal cup 1, and with the LED light source board 2
It is connected.The injection molded of lamp body shell 3 forms modeling alclad structure in the surface of heat dissipation metal cup 1.The lampshade 4 with
The top phase interlocking of the lamp body shell 3, the bottom phase interlocking of the lamp holder 5 and lamp body shell 3.The heat dissipation metal cup 1 is adopted
Use aluminum.
The radiator structure of LED of the present utility model, including heat dissipation metal cup 1, the outer injection of the heat dissipation metal cup 1 into
Shape has lamp body shell 3；The heat dissipation metal cup 1 has jatharapanvartanasana side wall, and the jatharapanvartanasana side wall inwardly convexes into a plurality of positioning
Boss 11, the cooperation plane of the upper surface composition interruption of a plurality of positioning boss 11；The LED light source board 2 is put down with the cooperation
Face is mutually abutted against, and is radiated by the cooperation plane.
The injection molded of lamp body shell 3 is when 1 surface of heat dissipation metal cup, the part of the corresponding positioning boss 11
Platform shape portion 31 is formed, the surrounding in this shape portion 31 connects with the thin-walled of uniform thickness, and each stress is balanced, is not likely to produce depression and becomes
Shape.
The upper surface of the positioning boss 11 is fan shape, and the cooperation of the upper surface composition of a plurality of positioning boss 11
Plane is the annular shape of interruption.
Shown in Figure 3, the width of the positioning boss 11 contacted with LED light source board 2 is D, and the wall thickness of heat dissipation metal cup 1 is
E；Overall center of circle angle corresponding to positioning boss 11 is B, and the center of circle angle not comprising wall thickness is A.Then have, the positioning boss 11
Total angle with hollow out interval is C, and is met Cn=360 ° (n is integer), and nA is total shrink angle.
NA is that total shrink angle is smaller, and outward appearance pit defect gets over unobvious.
(B-A) central angle corresponding to heat dissipation metal wall of cup thickness E, generally 2 ° or so, D width ranges are (1.5-
8) E is preferable；In view of the cost and difficulty of mould punching, the smaller punching press difficulty of B is bigger, so B can not be too small.
LED light source board 2 is arranged on boss, it is contemplated that and heat dissipation problem, the more radiating effects of the quantity of positioning boss 11 are better,
So n quantity can not be very few.Calculated by optimization, preferably, n quantity is 8-30, most preferably 10-12；B angle model
The angular range enclosed for (0.1-0.8) C, A is (0.1-0.95) B.Preferably, B scope is 15 °~36 °
Above-described embodiment is only used for further illustrating a kind of radiator structure of LED of the present utility model, but this practicality is new
Type is not limited to embodiment, every any simply to be repaiied according to what the technical essence of the utility model was made to above example
Change, equivalent variations and modification, each fall within the protection domain of technical solutions of the utility model.
