groove 12b1 on part two of another group LED module 7, increased the bonding strength of two groups of LED modules 7, especially can prevent that two groups of LED modules 7 are subjected to displacement, affect the reliability that two groups of LED modules 7 are electrically connected to.The both sides that assemble electrical interface 121 on part 12 are respectively equipped with connecting hole 125, and connecting hole 125 is for assembly connection device 8.Heat sink 13 is polyliths of arrangement parallel to each other, heat sink 13 is divided into long heat sink 131 and short heat sink 132 by difference highly, the cross section of long heat sink 131 and short heat sink 132 is all up-narrow and down-wide shape, and the height of long heat sink 131 and thickness are all greater than short heat sink 132, the outermost heat sink in fixed panel top 11 is long heat sink 131, distance between adjacent heat sink 13 is 4-6MM, its objective is and increase as much as possible area of dissipation, because the distance between adjacent heat sink 13 is limit, all heat sinks 13 all cannot be adopted to long cooling plate structure, all heat sinks 13 all adopt long heat sink 131 cannot complete when making, add short heat sink 132 to increase to greatest extent area of dissipation in manufacturing enforceable scope.Lens face shield 6 is fixed on radiating block 1, and water-tight circle 5 is arranged between lens face shield 6 and radiating block 1.Lens face shield 6 shapes are the squares that mate with fixed panel 11, lens face shield middle part 61 convexes to form cavity volume downwards with respect to edge, the edge of lens face shield 6 is fixed on the edge of fixed panel 11 bottoms by screw 66, specifically the edge of lens face shield 6 bottoms is provided with the mount pad 62 of a plurality of regularly arranged and downward protrusions, mount pad 62 is connected as a single entity with the edge of lens face shield 6, screw 66 is fixed on fixed panel 11 through mount pad 62, while adjusting LED3 or lens 4, just lens face shield 6 need to be pulled down, therefore the fixing mode of screw 66 is the most applicable, for the fastness that guarantees to install, therefore adopted respective outer side edges screw 66 fixing of mount pad 62.On lens face shield 6, be provided with fixed panel 11 junctions the groove 65 that holds water-tight circle, water-tight circle 5 is stuck in groove 65, and the effect that water-tight infiltrates can better be played in the inner side of the position of water-tight circle 5 in screw 66.The equal rule of edge of 4 sides of lens face shield 6 is provided with air-flow breach 63, article 4, air-flow breach 63 quantity, shape and the residing position on side is all identical, when 7 docking of two groups of LED modules, two air-flow breach 63 corresponding to position shape have been connected to form fluid space 631, fluid space 631 is accelerated to heat radiation for cross-ventilation, and the edge of every side is at least provided with 2 air-flow breach 63, like this LED module connecting place have at least 2 local to fluid space 631, for product lamp affixed to the ceiling or body seal, more effective.Lens 4 are airtight to be arranged on lens face shield 6, lens face shield 6 is provided with 12 lens installing holes 64,12 airtight being fitted on lens installing hole 64 of lens 4,12 lens 4 are arranged in 4 curved lenses bands that length is identical, article 4, curved lenses band joins end to end, and every curved lenses band forms by 5 lens arrangement.On pcb board 2, the quantity of LED3 and arrangement position mate with lens 4, each lens 4 directly over a LED3 is set, 12 LED3 are arranged in 4 arc LED luminous zones that length is identical, every arc LED luminous zone is arranged and is formed by 5 LED3.Above-mentioned 12 LED3 are low-voltage direct LED.For realizing the unification of variety classes LED alignment placement, LED module 7 has become 4 arc LED luminous zones by 12 low-voltage direct LED form Designs, so that 4 high-voltage LEDs in equidistant arrange evenly can be for replacing above-mentioned low-voltage direct LED, the low-voltage LED of generally applying by existing market is done on the basis of alignment placement, considered that thereby with plus-minus connection wire, changing the LED relation of arranging realizes the layout that is suitable for high direct voltage LED work, when needs are used high direct voltage LED instead, enough with 4 LEDs, in impartial position, use this 4 LEDs, all the other are with pin leads or wire UNICOM circuit, every module 48V/DC power supply for example, drive 12 3V low-voltage direct LED that single power is 1W, its pass of arranging is 12 strings, when using the 54V high-voltage LED that single power is 3W instead and driving with alternating current 220V or direct current 220V, the quantity of every pack module LED has just become 4, and this 4 LEDs must conspire to create a string, it is suitable that its position also must be placed, otherwise, will affect the attractive in appearance and illumination of layout evenly.Under different voltage and different capacity class, the width of Copper Foil wire and spacing requirement are different, power hour, and because its load capacity is little, Copper Foil wire can be more carefully; When voltage is low, because of pressure reduction little, wire pitch also can be less, for accomplishing the compatibility of same pcb board to different voltage and different capacity class, LED module 7 special designs width and the gap of Copper Foil wire, the current-carrying capacity of Copper Foil wire is relevant with the thickness of Copper Foil, conductor width and operating temperature etc., and creep age distance is relevant with the dielectric constant of material with the spacing of wire.It for copper thickness, is the conventional pcb board of 1 ounce, when operating temperature is 20 degree, when Copper Foil conductor width is 0.254mm, can bear the electric current of about 1.2A, the electric current that for the benefit of many pack modules connection in series-parallel realizes the above power of whole lamp 120W bears, its the narrowest width of Copper Foil wire that LED module 7 is connected with power supply is all more than 2.5mm, can guarantee to bear the electric current of 4.5A left and right, as for creep age distance, to ordinary electronic circuit, it is less demanding, be greater than 0.2mm enough, creep age distance is 0.8mm, enough surpluses have been reserved, effectively avoided increasing the current overload causing and effectively having prevented because using AC LED and HVDC LED to cause the creepage risk that load voltage raises and produces because of module parallel combination.Above-mentioned special design has realized variety classes LED and has shared the compatibility imagination that a pcb board shares one group of lens outer cover, has facilitated production, has also reduced material cost.

When above-mentioned electrical interface 121 is not used in docking, opening generally seals up with capping, and the obsolete electrical interface 121 use capping sealings of especially corresponding threading via hole 112 can better promote IP degree of protection.The all position preventing dust water-based of LED module 7 is all very good, and IP degree of protection is high, reaches 66 grades, meets the condition of outdoor use completely, does not need to increase the shell that keeps off the rain and just can directly use out of doors.By the energising interface 21 on the pcb board 2 that assembles part 12 and mate with it of fixed panel 11 bottom surface side edges, realized in LED module surrounding and kept somewhere expansion edge, realize LED module 7 Combination conversions of different purposes, different capacity class, to facilitate consumer's multipurpose requirement, can easily a plurality of LED modules 7 be docked and be combined, simultaneously assembling part 12 and can fix for the installation of LED light fixture in docking position not.

Jockey 8 comprises the electric connector of fixture and process IP protective treatment, two groups of LED modules 7 are connected by fixture, fixture is connected to position on every group of LED module 7 all in assembling on part 12, and the pcb board 2 on two groups of LED modules 7 is realized electrical connection by electric connector.
