Embodiment
Please refer to shown in Fig. 1 to Fig. 9, that show the concrete structure of the preferred embodiment of the utility model, it is a kind of high-brightness LED support, its structure comprises two conductive feet 10 and the insulating base 20 with this two conductive feet 10 one produced by insert molding, the recessed formation of end face of this insulating base 20 is for installing the reflector 30 of LED wafer, when making finished product, by LED chip die bond in this reflector 30, recharge fluorescent material.
Wherein, as shown in Figures 1 to 5, this reflector 30 is polygon, and the rim of a cup of reflector 30 has the first reflective surface 31, the lighting angle α of this first reflective surface 31
1it is 20 °.There is the second reflective surface 32, the lighting angle α of this second reflective surface 32 at the bottom of the cup of reflector 30
2it is 20 °.The lighting angle α of the 3rd reflective surface the 33, three reflective surface 33 is formed between the first and second reflective surfaces 31,32
3be 115.66 °, and the area of the 3rd reflective surface 33 is greater than the area of the first and second reflective surfaces 31,32.Because cup causes along there being excessive glue the phenomenon that product light efficiency reduces when this kind of structural design can prevent product from lighting; In the reflector 30 of another product, there is multiple lighting angle, the refraction of light can be increased, product brightness is improved.
The reflector 30 of LED support of the present utility model has the two long inclined-planes 34 arranged face-to-face, the two short inclined-planes 35 arranged face-to-face, connects four intermediate incline 36 between this two long and short inclined-plane 34,35 respectively.This long inclined-plane 34, short inclined-plane 35 and intermediate incline 36 are trapezoidal.From size, the length L1 of reflector 30 rim of a cup is 2.85mm, and the width L2 of rim of a cup is 2.5mm, and the length L3 at the bottom of reflector 30 glasss is 2mm, and the width L4 at the bottom of cup is 1.65mm.
As shown in Figure 6 and Figure 7, described two conductive feet 10 surfaces thin with the binding site of insulating base 20 groove 11 formed for biting plastic cement.The outside of conductive feet 10 is provided with groove 12 and protruding 13, so that be combined with insulating base 20 better in place outside.In addition, the bottom surface periphery of described two conductive feet 10 is arranged with the hanging platform 14 for biting insulating base 20.So, two conductive feet 10 are firmly together with insulating base 20 produced by insert molding, the effective minimizing below plastics of punch press process to insulating base 20 pulls, groove 11 can effectively prevent red ink from testing infiltration, groove 12, projection 13 and hanging platform 14 bite insulating base 20, fix the geometric position of two conductive feet 10, prevent two conductive feet 10 from freely pulling and cause processing difficulties and quality problems.
As shown in Figure 7, the bottom surface of described two conductive feet 10 is one-body molded fin 15, and this fin 15 flushes with the bottom surface of insulating base 20.The separate type of traditional heat-dissipating copper coin is become integral type by this kind of design, the design of tradition separate type, its heat radiation copper coin and conductive feet respectively open one set of die, again heat radiation copper coin and conductive feet are stacked in plastic mould with insulating base produced by insert molding, there is Mould Machining cost undoubtedly expensive, mould processing technology is complicated, the series of problems such as assembling difficulty and tolerance value complexity.Now fin 15 and conductive feet 10 are set to one, at same set of in-mold molding, conductive feet 10 directly stamping-out and without the need to bending, this structure comparatively before the processing charges of bending structure mould low, tool mould-forming process is simple.
As shown in Figure 8 and Figure 9, described conductive feet 10 is by a copper coin punch forming, and on the copper coin support 40 after shaping, often row has 14 groups of conductive feet 10, and the PIN distance between two adjacent groups conductive feet 10 is 5.2mm, this kind of arrangement has compact conformation, the advantage of conservation.
In sum, design focal point of the present utility model is, reflector 30 is set to polygon, and the light-emitting area of multiple different angles is set in reflector 30, because cup causes along there being excessive glue the phenomenon that product light efficiency reduces when this kind of structural design can prevent product from lighting; In the reflector 30 of another product, there is multiple lighting angle, the refraction of light can be increased, product brightness is improved.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
