Abstract
An LED copper column provided in the utility model includes a cylindrical main part, an upper end part arranged over the cylindrical main part and a lower end part arranged below the cylindrical main part. The lower end part includes an external end surface and an inner end surface; the peripheral surface of the cylindrical main part is provided with lines; and the lines comprise crossingly arranged lines. Because the peripheral surface of the cylindrical main part is provided with lines, the combination force of the LED copper column and a plastic part is enforced after injection molding, the LED copper column is hard to separate from the plastic part, the combination is firm, simultaneously, the adaptation and air tightness of the LED copper and the plastic part are enhanced, and an extraneous foreign matter is prevented from filtering and influencing the usage life of a chip and the illuminant effect of the LED.
Description
Technical field
The utility model relates to a kind of LED copper post.
Background technology
In the prior art, led chip extensive use owing to have effect such as luminous efficiency height, environmental protection and energy saving, long service life is along with the application of great power LED; Higher because of high-power LED chip brightness, therefore, its heat of supervening is also more concentrated; Heat is high, if the untimely heat that produces is conducted distributes, not only can influence the useful life of led chip; And, each components and parts of LED lighting device are burnt out.The integrated form heat radiation copper post that wafer is installed generally need combine with plastic parts.Yet existing heat radiation copper post is generally smooth face, this heat radiation copper post when combining with plastic parts, in conjunction with dynamics and adaptation relatively poor, make heat radiation copper post and plastic parts combine firm inadequately.
Summary of the invention
The technical problem that the utility model will solve provide a kind of bond strength and adaptation better, excellent in heat dissipation effect, the LED copper post that radiating rate is fast.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: comprise the main part that is column type, and be arranged on the upper end of main part top, and be arranged on the bottom of main part below; Said bottom comprises outer face and inner face; Said main part peripheral surface is provided with lines, and said lines is that the line of cross arrangement is formed.
Further, the lines on the said main part is an inclined design.
Further, the lines on the said main part is perpendicular to the bottom.
Further, the lines on the said main part is a design levels.
Further, said upper end is provided with and the contacted groove of led chip.
The LED copper post of the utility model is because said main part peripheral surface is provided with lines, through the setting of lines; Strengthen the adhesion of LED copper post and plastic parts after the injection moulding; Make it be difficult for separating,, increase the adaptation and the air tightness of LED copper post and plastic parts simultaneously in conjunction with firmly with plastic parts; Prevent the infiltration of extraneous foreign matter, thereby have influence on the life-span and the luminous effect of LED of chip.
Description of drawings
Fig. 1 is the vertical view of the utility model LED copper post;
Fig. 2 is the front view of the utility model LED copper post.
Embodiment
In the present embodiment, referring to figs. 1 through Fig. 2, said LED copper post comprises the main part 1 that is column type, and is arranged on the upper end 2 of main part 1 top, and is arranged on the bottom 3 of main part 1 below; Said bottom 3 comprises outer face 30 and inner face 31; Said main part 1 peripheral surface is provided with lines 10, and said lines 10 is formed for the line of cross arrangement.Through the setting of lines, strengthen the adhesion of LED copper post and plastic parts after the injection moulding, make it be difficult for separating with plastic parts, adhesion is good, in conjunction with firmly, increases the adaptation and the air tightness of LED copper post and plastic parts simultaneously.
In the present embodiment, the lines on the said main part 1 is an inclined design.Certainly, the lines on the said main part 1 also can be design levels, and the lines on the perhaps said main part is perpendicular to the bottom.In addition, be provided with and the contacted groove 20 of led chip in said upper end 2.
The LED copper post of the utility model is because said main part peripheral surface is provided with lines, through the setting of lines; Strengthen the adhesion of LED copper post and plastic parts after the injection moulding; Make it be difficult for separating,, increase the adaptation and the air tightness of LED copper post and plastic parts simultaneously in conjunction with firmly with plastic parts.
Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
