The invention discloses a fixing structure for an LED lighting lens and a PCB. The fixing structure comprises the PCB where LED lamp beads are welded and the plastic lens covering the LED lamp beads. Surface-mounted metal buckles used for being connected with the plastic lens in a buckling mode are welded on the surface of the PCB, and the PCB is connected with the plastic lens in a buckling mode through the surface-mounted metal buckles of the PCB. The fixing structure for the LED lighting lens and the PCB is more concise in assembling and higher in efficiency and precision.
Description
Technical field
The present invention relates to the fixed structure of LED illumination lens and pcb board.
Background technology
LED illumination lens of the prior art and the cooperation between circuit board adopt following several mode substantially: 1) lens are screwed on radiator together with pcb board, 2) lens utilize buckle by pcb board pressure holding on radiator, 3) lenslet of individual particle formula directly coordinates with the buckle on great power LED, or the lenslet of individual particle formula is received on pcb board by gluing, 4) also have and lens are fixed to pcb board by additional parts as support or both is fixed on radiator together.3) fixed form packaging efficiency is too low and cost is high, will be substituted by monoblock type lens gradually.And 1), 2), 4) mode adds error accumulation between lens and light source.
Summary of the invention
The object of the present invention is to provide the fixed structure of a kind of LED illumination lens and pcb board, its assembling is more succinct, and efficiency is higher, and precision is higher.
For achieving the above object, technical scheme of the present invention is the fixed structure of a kind of LED illumination lens of design and pcb board, comprising: the pcb board being welded with LED lamp bead, and for covering the plastic lens of LED lamp bead;
Described pcb board surface soldered has the SMD metal card fastener connecting plastic lens for buckle;
Described pcb board is connected with plastic lens buckle by its SMD metal card fastener.
Preferably, described pcb board surface is provided with the pad for soldering surface mounted formula metal card fastener, described SMD metal card fastener by Placement on pad.
Preferably, the circuit of described pad and pcb board is isolated.
Preferably, described SMD metal card fastener adopts coiled strip packaging.
Preferably, the material of described plastic lens is PC or PMMA.
Preferably, the sheet material of described pcb board is FR4, CEM1, CEM3 or aluminium base.
Preferably, described plastic lens comprises: for the panel on the pcb board surface that reclines, and by panel outwardly convex, for covering the lens cap of lamp pearl group; Described SMD metal card fastener is connected with panel fastener.
Preferably, described panel is provided with multiple buckling grooves of outwardly convex; Described SMD metal card fastener coordinates with buckling groove one_to_one corresponding; Single SMD metal card fastener snaps in corresponding buckling groove, and forms buckle with this buckling groove and be connected; Described panel is connected with the buckle of SMD metal card fastener by above-mentioned buckling groove and fixes with pcb board.
Preferably, described buckling groove is located at the edge of panel, and every bar edge is at least provided with two buckling grooves.
Advantage of the present invention and beneficial effect are: the fixed structure providing a kind of LED illumination lens and pcb board, and its assembling is more succinct, and efficiency is higher, and precision is higher.
Lens and PCB lamp board are formed stand-alone assembly, makes final lamp installation more flexible.
SMD metal card fastener is applicable to the making technology of paster, and can increase production efficiency, cost is lower, is more easily formed as a kind of industry universal specification.
Fixed structure of the present invention has certain universal significance to be also, has the different luminous intensity distribution of requirement, and will become very convenient for replacing lens, need not consider that other additional elements affects in different practical application.Because present most situation adopting screw mode fixing, screw torsion size to be considered during replacing, waterproof etc. requirement, fixed structure of the present invention by they with realize light distribution requirements and separate completely.
The present invention also has following features:
(1) effect of lens is by the light-ray condensing of LED light source to the place required, dimension chain can be made the shortest with the pcb board at LED place is directly fixing, between lens and light source, precision can reach the highest, and the luminous intensity distribution of different product is more consistent.In actual design scheme, because lens should consider light distribution requirements, consider waterproof again, easy assembling, easy processing and being connected etc. with other parts, dimension chain design can be very complicated, especially on z direction and height, required precision is very high, because any height error slightly will be completely different to luminous intensity distribution, fixed form of the present invention just in time can make dimension chain between lens and lamp pearl reduce to almost minimum, the light distribution requirements of all is only relevant with the relative position of the SMD metal card fastener that pcb board welds with lens, make assembling more succinct, efficiency is higher, precision is more increased.
(2) lens and pcb board is easily made, and SMD metal card fastener becomes individual components, thus can modular small be realized, development is in the future applicable to becoming core standard parts to ensure product quality more, the more important thing is, along with the universal of this mode will obtain than existing any fixed form higher price-performance ratio advantage.
(3) fixed structure of the present invention's design is with certain universal significance, application not only out of doors in light fixture, luminous intensity distribution, waterproof etc. can be made to utilize this fixed form to solve, and in indoor lamp, the plastic lens of the extrusion moulding of panel light and the combination of paster hardware can bring the benefit described in above 2, in the individual particle lens application of taking the photograph lamp, same fixed form also can be used to do overall lens and improve efficiency of assembling and properties of product, improving product cost and competitiveness simultaneously.
