Particularly, described son lures the length of rail 51 can be according to actual needWant and determine, not repeating them here.
Further, during Fig. 4 shows according to a preferred embodiment of the present invention, with luring railThe structure that lures rail of LED lamp. Preferably, as shown in Figure 4, described multiple sons lure rail 51Junction has stop part 52. The object that designs described stop part 52 is to prevent that son from luring between railInterconnect, lure the submounts 6 in rail 51 mutually to touch thereby prevent from stretching into described son, therebyAvoid the interference between submounts 6. Further, it will be appreciated by those skilled in the art that stop part52 set-up mode has multiple, for example, if described son lures rail and bulb housing 1 one, canUtilization lures the cross section of rail 5 top self-assembling formations as stop part 52, described in generating, lures rail 5Time, multiple sons are not lured between rail 51 and got through at its head portion, but reserve enough materialsMaterial, for example, while luring rail 51 by son described in etched mode carve on described bulb housing 1,Lure rail 51 part that crosses not carve at multiple sons, thereby form described stop part 52. AgainFor example, in the time suppressing described bulb housing 1 by mould one-shot forming, described mould is corresponding to instituteStating and luring the head portion of rail 5 is hollow, thereby this part can nature in the time luring rail 5 described in compactingForm described stop part 52. Further, it will be appreciated by those skilled in the art that described stop part 52All be positioned at the top of bulb housing 1. And change in example at another, if described in lure rail 5 to be and lampCell-shell 1 separates, and conventionally can adopt independent mould to lure rail described in generating, similarly,Described mould is set to the structure that lures tread end to be divided into hollow corresponding to described, thereby forms toolWhat have described stop part 52 lures rail 5, does not repeat them here. Correspondingly, those skilled in the art's reasonSeparate, in such variation example, described stop part 52 is preferably arranged on son and lures the top of rail 51,Shape can be circle or rectangle, takes the mode of bonding to be fitted in son and to lure the top of rail 51.
Further, in conjunction with above-mentioned Fig. 3 and embodiment illustrated in fig. 4, those skilled in the art's reasonSeparate, preferably, described son lures the length of rail 51 to be less than the length of described submounts 6. This designObject be to ensure submounts 6 can possess can be movable part, extend at submounts 6Son lures in the process of rail 51, prevents that son from luring rail 51 that submounts 6 is blocked, and causes submounts distortion.Further, it will be appreciated by those skilled in the art that as fruit lures rail 51 and bulb housing be one,Son lures the size of rail 51 length directly to have influence on the intensity of bulb housing and the difficulty of moulding so,It is the length that is less than described submounts 6 that son is lured to the Design of length of rail 51, can more convenient moulding.
Further, it will be appreciated by those skilled in the art that described son lures end and the described son of rail 51The part that substrate 6 attaches is the acclive structure of tool. For example, adopt etched mode to form and lure rail,Can in the time that luring rail 51 end, engraving take the method that changes gradually the etched degree of depth to form necessarilyThe gradient. Again for example, adopt the mode of mold pressing to produce while luring rail, lure rail 51 ends corresponding at sonMould part is designed to be with acclive structure. The advantage of this design is, described son lures rail 51Tip designs be that gradient structure can make described submounts 6 more easily stretch into, and at submounts6 extend into son completely lures after rail 51, can have certain move place, prevents that submounts quilt from luringRail 51 pushes and is out of shape.
Preferably, as shown in Figure 5, what described son lured rail 51 is shaped as groove shape. This area skillArt personnel understand, and the track in industrial design is generally all designed to groove shape, and groove is easy to processing,And can control the stability of its size, also more easily match with the shape of submounts 6. ExampleAs, in the time that the shape of submounts 6 is comparatively complicated, can make son lure the size of rail 51 to be a bit larger tham sonThe size of substrate 6, ensures that submounts 6 is well contained in son and lures in rail 51. By suchGroove shape design, while making described submounts 6 insert described son to lure rail 51, described submounts 6Can insert described son along described groove and lure rail 51, thereby be more prone to control described insertionJourney, does not repeat them here.
Further, described in it will be appreciated by those skilled in the art that, lure the molding mode of rail 5 to have multiple,For example, can be formed at by surface etching or pressing process the inner surface of described LED bulb housing 1,No matter adopt which kind of technique, all do not affect essentiality content of the present invention, its final purpose all makesLure rail 5 to be depressed in the inner surface of described LED bulb housing 1, do not repeat them here.
Further, lure described in it will be appreciated by those skilled in the art that described in the thickness of rail 5 is preferably50% of the thickness of LED bulb housing 1. Lure the thickness of rail 5 unsuitable blocked up or excessively thin, blocked up meetingAffect the intensity of bulb housing 1 own, mistake is thin is unfavorable for that submounts 6 is in the movement luring in rail 5.
Change in example at another, as shown in Figure 6, described in lure rail 5 to can be designed as individual components,Be separated with bulb housing 1, so more easily independent processing and forming. For example,,, lureRail 5 can be designed as the mechanism of rectangular band groove, and material can be selected glass or plastics etc., adoptsWith the mode moulding of mold pressing, be attached to the inwall of bulb housing 1 by the mode of bonding.
Further, described in it will be appreciated by those skilled in the art that, lure rail 5 to be designed to independently parts,The described each son that lures rail 5 lures between rail 51 and can each other independently, be fixed on separately respectively lampThe inwall of cell-shell 1; Also can interconnect each other, make the as a whole bulb housing that is fixed onWhich kind of mode no matter 1 inwall, adopt, and all do not affect flesh and blood of the present invention, at this no longerRepeat.
