In the present embodiment, in order to solve the long-time easily defect of bulging deformation of rear its middle part of using of existing LED set of lenses, this set of lenses 1 has been re-started to the optimal design of structure, on lens pedestal 11, be provided with some reinforcements 111, referring to Fig. 1, those reinforcements comprise five cross reinforcings that are parallel to LED lens group leader limit, wherein one is arranged between two row's lens, in addition four are divided into two groups, and two every group, those group cross reinforcings are separately positioned on the both sides of LED set of lenses; Reinforcement on lens pedestal 11 also comprises nine walings that are arranged between set of lenses and are parallel to the minor face of LED set of lenses, those walings intersect mutually with three cross reinforcings that close on lens setting, and, in each crosspoint except arranging screw accommodating hole 13, be equipped with the circular structure of strengthening, with the fault of construction that prevents from adopting square chi structure to bring; And, on the two groups of cross reinforcings of both sides that are arranged on LED set of lenses, be also respectively equipped with one group of short reinforcement, in those groups, each short reinforcement is all vertical with cross reinforcing, and one end of each short reinforcement connects that cross reinforcing that lens arrange that closes on of every group of cross reinforcing, and the other end of each short reinforcement stretches out outside another cross reinforcing of respective sets; Above LED lens group structure, for rectangle set of lenses, can effectively prevent the long-time bulging deformation phenomenon of using rear generation in set of lenses middle part.In other embodiment of the present utility model, reinforcement also can only be parallel to the long limit of lens pedestal or only be parallel to the minor face of lens pedestal, or part reinforcement is parallel to the long limit of lens pedestal, and another part reinforcement is parallel to the minor face of lens pedestal.The intensity that reinforcement can significantly improve set of lenses is set on lens pedestal, prevents its intermediate projections after long-time use, produce distortion.
In addition, in order to reach the effect that better prevents set of lenses 1 intermediate projections distortion, will be set to for connecting some buckles 6 of set of lenses 1 and radiator 4: the buckle that the buckle quantity arranging at the middle part, long limit of lens pedestal 11 arranges than other positions is more intensive.In the present embodiment, the both sides in the middle part of the long limit of lens pedestal 11 respectively arrange 4 buckles, and at the minor face of lens pedestal 11,2 buckles are set, and the edges at two ends on each long limit respectively arranges 1 buckle, referring to Fig. 1 and Fig. 2.The advantage of this structure is: at lens pedestal middle part, more buckle is set, is fitted more closely with radiator in its middle part, due to the fixation of a plurality of buckles in the middle part of lens pedestal, can more effectively prevent the bulging deformation at set of lenses middle part.
Conventionally in the set of lenses 1 of LED module, be all provided with and keep away wire casing 10 for accommodating electric wire, due to existing, be provided with cross to keep away the LED module integral width of wire casing wider, so need more raw material, caused the rising of cost, in the present embodiment, the shape of keeping away wire casing 10 is redesigned, keep away wire casing 10 and be designed to bar shaped, its area occupied is reduced, arranging of lens adjusted simultaneously, all lens are divided into two rows to be arranged, wherein a row middle part is available, the part being available is kept away wire casing 10 for arranging, for example, referring to Fig. 1 and Fig. 2, lens add up to 18, wherein a row arranges 10 lens, another row arranges 8 lens, wire casing 10 is kept away for arranging in the middle position of vacating two lens of a row that 8 lens are set, and two row's lens adopt symmetrical mutually mode to arrange.Above, 10 and 8 quantity is only a concrete example, is not used in and limits protection domain of the present utility model.And, because the set of lenses that makes set of lenses 1 keep away wire casing than original use cross by above-mentioned setting obviously narrows down, correspondingly, circuit board 3 and radiator 4 also narrow down, originally need to could fixing circuit boards and radiator with four screws, after design improvement, circuit board and radiator obviously narrow down in the present embodiment, therefore use two screws just can very firmly circuit board 3 and radiator 4 be fixed, in set of lenses 1, only need to arrange two screw storage tanks 13 for the end of accommodating screw simultaneously.Material has not only been saved in such Optimal Structure Designing, and the while is the corresponding number that has reduced the screw storage tank being arranged on lens pedestal also, and the decreased number of screw storage tank is more conducive to the design that narrows of set of lenses and LED module.
Embodiment bis-
Referring to Fig. 7 and Fig. 8, the lens in the present embodiment and comparing in embodiment mono-, have following distinctive points:
The distance at the lens in set of lenses 1 ' and lens pedestal 11 ' edge is narrower, is convenient to so the narrow type of set of lenses and LED module, more saves raw material; Circuit board, radiator be corresponding narrowing down also, to mate with set of lenses;
The arrangement mode of set of lenses 1 ' upper lens is different: lens 12 are divided into two rows and arrange, and at the two ends of these two rows lens, lens is set respectively again, keeps away wire casing 10 and is arranged on the wherein middle part of row's lens.For example, in Fig. 7, lens numbers is 16, wherein 8 set of lenses are in a row, another 6 lens form another row, two remaining lens are arranged on the both ends of two row's lens, and wire casing 10 is kept away for arranging in the position of vacating two lens in the middle of that row who comprises 6 lens, wherein two row's lens adopt symmetrical mutually mode to arrange.Above, 8,6 and 16 etc. quantity is only a concrete example, for limiting protection domain of the present utility model.
The shape of set of lenses 1 ' upper liquid silicon cushion rubber groove 112 ', in embodiment 1 due to set of lenses wider width, the edge of the more close lens pedestal of liquid silicon cushion rubber groove setting, thereby in the position that buckle 6 is set, liquid silicon cushion rubber groove narrows down, in the present embodiment, the whole medial movement to LED set of lenses of liquid silicon cushion rubber groove 112 ' a little, thereby the width that makes liquid silicon cushion rubber groove remains unanimously, does not also narrow down, referring to Fig. 8 in the placement of buckle 6.Width is consistent and can better keeps intensity.
