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, the LED module special design of this patent 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 multimode connection in series-parallel realizes the above power of whole lamp 120W bears, its the narrowest width of Copper Foil wire that the LED module of this patent 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, the creep age distance of this patent 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.
Above-mentioned electrical interface 121 is through IP protective treatment, IP protective treatment refers to the processing that meets IP degree of protection, the IP protective treatment mode of electrical interface 121 is a lot, conventional for example in the surrounding of electrical connector, set up water-tight packing ring, or arrange the closing cap of electrical interface 121 sealings at the outer of electrical interface 121, and above-mentioned by impact, be the IP protective treatment mode that transparent threading screens groove 111 structures all belong to electrical interface 121, adopt the LED module IP degree of protection of technique scheme at least to reach 66.When above-mentioned electrical interface 121 is not used in docking, its opening generally seals up with capping, and the obsolete electrical interface 121 of especially corresponding threading via hole 112 need to be used capping sealing.The kind of above-mentioned electrical connector is a lot, and conventional is binding post.
LED module as shown in Figure 8, other structure is identical with the LED module of embodiment 1, and part-structure and function on the basis of embodiment 1, have been increased, heat sink 13 is specifically provided with the erection column 133 with screw being connected as a single entity with it, screw opening upwards, connecting plate 134 is installed on erection column 133, and mounting screw is fixed on erection column 133 through connecting plate 134, and connecting plate 134 can be fixed for the installation of whole LED module.For docking assembling of LED module, electrical connector 124 is set on part 12, through IP, protective treatment all arranges water-tight packing ring at electrical connector 124 to electrical connector 124 up and down, being not used in the assembling on part 12 of joint, with capping 122, clog electrical interface 121 in addition.
LED module as shown in Figure 9, other structure is identical with the LED module of embodiment 1, and part-structure and function on the basis of embodiment 1, have been increased, specifically assemble on part 12 and arrange connecting plate 123 is installed, screw is fixed in connecting hole 125 through connecting plate 123 is installed, and perforate on connecting plate 123 is installed.This assembles that part 12 does not rise connection function and works the function of installing, and by connecting plate 123 is installed, can fix for the installation of whole LED module.Heat sink 13 is in addition provided with the erection column 133 with screw being connected as a single entity with it, screw opening upwards, and erection column 133 can fixing for LED module alternate manner.For docking assembling on part 12 of LED module, electrical connector 124 is set, through IP, protective treatment all arranges water-tight packing ring at electrical connector 124 to electrical connector 124 up and down.
Above-mentioned 3 embodiment are only preferably embodiment of this patent, and the shape of fixed panel can be adjusted variation, such as regular hexagon, octagon, semicircle etc., and best mode is square.Variation can be adjusted in the quantity that assembles part and position on fixed panel, the quantity that assembles part can be 1, just can only realize the connection of 2 LED modules, assemble part and on electrical interface 121 can be a plurality of, such as 2,3,5 or 6 etc., the energising interface quantity on pcb board be need to the reserved electrical interface that can switch on 121 quantity Matching.In addition, in embodiment 1,4 threading positions can be all threading via holes 112, can be partly also threading via holes 112.The all position preventing dust water-based of LED module in above-described embodiment is all very good, and IP degree of protection is high, reaches 66, 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 the Combination conversion of different purposes, different capacity class, to facilitate consumer's multipurpose requirement, can easily a plurality of LED modules be docked and be combined, simultaneously assembling part and can fix for the installation of LED module in docking position not.
When LED module is used separately, by switch and the brightness regulation of the IC chip controls LED3 on pcb board 2, the light scioptics 4 that LED3 sends penetrate, the heat producing during LED3 work is dissipated by radiating block 1, IC chip 22 on pcb board 2 is controlled the operating current of LED and the work calories of LED by pulse width modulating technology, by changing dutycycle, carry out the adjustment of voltage stabilizing and constant current, by pulse width modulating technology PWM, realize voltage stabilizing and constant current, by IC chip monitoring LED operating temperature, realize temperature protection function, when surpassing setting index, automatically reduces internal temperature the stable work in work that electric current guarantees LED, by changing the method for dutycycle, implement voltage stabilizing, effectively lowered the fluctuation of voltage, improve LED constant current and driven effect, specifically at IC chip internal, be integrated with overheat protector device, even connected triode conducting after its temperature sensor is experienced temperature to surpass a certain value, by shunting, lower operating current, thereby realize desuperheat effect, pulse width modulating technology PWM regulates the biasing of transistor base or metal-oxide-semiconductor grid and then realizes transistor or a kind of analog control mode of metal-oxide-semiconductor ON time change according to load change, and this mode can make the output voltage of power supply remain constant when operation conditions change.When two or more sets LED module docking, adjacent LED modules connects at part 12 places that assemble separately by connector, by connector and electrical interface, adjacent LED modules is electrically connected, and gets final product the independent assortment of utility modules.
