Summary of the invention
The utility model provides a kind of LED electrical electrode structure, and object is that solving existing adopting surface mounted LED exists the problem being connected defective tightness between metal electrode with encapsulating shell.
The utility model adopts following technical scheme:
A kind of LED electrical electrode structure, comprise a positive electrode and a plurality of negative electrode, above-mentioned negative electrode is provided with negative pin, and above-mentioned positive electrode is rectangle, and one end of this positive electrode length direction is provided with a positive pin; The two ends of above-mentioned positive electrode Width are equipped with a plurality of being intervally arranged and L-shaped projecture, and a plurality of above-mentioned negative electrode is arranged at the two ends of positive electrode length direction with being intervally arranged, and is reserved with gap between negative electrode and positive electrode.
Further, the cross-sectional profiles in the gap between above-mentioned negative electrode and positive electrode is in falling convex shape.
Further, the upper surface of above-mentioned positive electrode is provided with a plurality of groove for placing wafer.
Further, the quantity of above-mentioned negative electrode and groove is 3, and one end that wherein above-mentioned positive electrode length direction is provided with positive pin is provided with a negative electrode, and the other end is provided with two negative electrodes.
Further, above-mentioned positive pin and negative pin include linkage section and welding section, and the junction of linkage section and welding section is provided with through hole.
From the above-mentioned description to the utility model structure, the utility model tool has the following advantages:
In one, the utility model, the two ends of positive electrode Width are equipped with a plurality of being intervally arranged and L-shaped projecture, a plurality of described negative electrode is arranged at the two ends of positive electrode length direction with being intervally arranged, and is reserved with gap between negative electrode and positive electrode.Projecture makes two end surfaces irregularities of positive electrode Width, strengthens the connection between positive electrode and encapsulating shell, prevents positive electrode from loosening.
Two, in the utility model, the cross-sectional profiles in the gap between negative electrode and positive electrode in falling convex shape, can overcome positive and negative electrode exposed in the light trough of encapsulating shell time easily tilt the problem causing positive and negative electrode and encapsulating shell to be separated.
Three, in the utility model, above-mentioned positive pin and negative pin include linkage section and welding section, and the junction of linkage section and welding section is provided with through hole, make the part that there is socket mutually between encapsulating shell and positive and negative electrode, slide to prevent positive and negative electrode; Through hole also makes pin easily bend in the junction of linkage section and welding section simultaneously, is conducive to pin forming.
