Refer to Fig. 1 and Fig. 2, the present invention provides a kind of LED straight lamp in an embodiment, comprising: a glass lamp 1, is located at the lamp plate 2 in glass lamp 1, and is respectively arranged on two lamp holders 3 at glass lamp 1 two ends.The size of described lamp holder is identical or different.Refer to Figure 1A, in the embodiment that the size of described lamp holder differs, it is preferable that described less lamp holder is of a size of the 30% to 80% of relatively headlight area of bed.Further, described glass lamp and lamp holder can use the silica gel of a kind of high heat conduction to fix, the silica gel heat conductivity >=0.7w/m.k (not shown) of described high heat conduction.
Optionally, described glass lamp can also encase glass lamp with heat-shrink tube, and glass lamp is carried out insulation processing.Optionally, the thickness range of described heat-shrink tube is 20 μm to 200 μm, and good thickness range is 50 μm to 100 μm (not shown).
Optionally, the inwall of described glass lamp forms a rough surface, the smooth outer surface face of glass lamp, it is, the roughness of glass lamp inwall glass lamp outer surface is big.The roughness Ra 0.1-40 micron of glass lamp inwall, good, the roughness Ra 1-20 micron of glass lamp inwall.Surface roughness can use tool processing method or change method to be formed, tool processing method, when such as, in course of processing friction between cutter with piece surface, chip separate, the dither etc. in the plastic deformation of surface layer metal and process system, changes rule as changed rotten method.Different processing methods and the difference of workpiece material, the depth, density, shape and texture that surface to be machined is left a trace have difference, it is possible to according to the light required for LED.
Refer to Fig. 2,3, in other embodiments, lamp holder provided by the present invention is provided with the hole 304 for dispelling the heat.Thereby, make way for the heat that power supply module within lamp holder produces and can leave and be in the condition of high temperature inside lamp holder without causing, to avoid the reliability of lamp holder inner member to decline.Further, hole lamp holder being used for dispelling the heat is arc.Further, hole lamp holder being used for dispelling the heat is three camber lines not of uniform size.Further, hole lamp holder being used for dispelling the heat is ascending three camber lines gradually changed.Further, on lamp holder, the hole for dispelling the heat can be above-mentioned arc, and the arbitrarily collocation of camber line is constituted.
In other embodiments, lamp holder includes one for installing the power supply slot (not shown) of power supply module.
With reference to Fig. 4, in the glass lamp 1 of the present embodiment except the lamp plate 2 (or bendable circuit soft board) being close to glass lamp 1, also including diffusion barrier 13, the light that light source 202 produces passes glass lamp 1 by after diffusion barrier 13.The light that light source 202 sends is played the effect of diffusion by diffusion barrier 13, therefore, as long as glass lamp 1 is passed after making light therethrough diffusion barrier 13 again, the layout of diffusion barrier 13 can have various ways, such as: diffusion barrier 13 can be coated or covered with on the inner peripheral surface of glass lamp 1, or it is coated on the diffusion coating (not shown) on light source 202 surface, or covers (or covering) diffusion barrier sheet outside light source 202 as an outer housing.
Referring once again to Fig. 4, when diffusion barrier 13 is diffusion barrier sheet, it can cover on outside light source 202, and does not contact with light source 202.The general term of diffusion barrier sheet is optical diffusion sheet or optical diffusing plate, arrange in pairs or groups diffusion particle typically by the combination of one or more in PS polystyrene, PMMA polymethyl methacrylate, PET (polyethylene terephthalate), PC (Merlon), a kind of composite formed, diffusion phenomenon can be there is when this composite of light therethrough, light uniformly area source can be revised and finally make to be distributed from the brightness uniformity of glass lamp with the effect reaching optics diffusion.
When diffusion barrier 13 is diffusion coating, its main component can be calcium carbonate, calcium halophosphate activated by antimony andmanganese and aluminium oxide wherein any one, or the wherein combination of wantonly two kinds, or the combination of three kinds.When the diffusion coating utilizing calcium carbonate to be formed for the main material suitable solution of collocation, will there is excellent diffusion and the effect of printing opacity (having an opportunity to reach more than 90%).
In the present embodiment, when allotment, the constituent of diffusion coating includes calcium carbonate, strontium phosphate (such as CMS-5000, white powder), thickening agent and ceramics activated carbon (such as ceramic active carbon SW-C, colourless liquid).Specifically, when diffusion coating is with calcium carbonate for main material, arrange in pairs or groups thickening agent, ceramic active carbon and deionized water, it is coated on the inner peripheral surface of glass glass fluorescent tube after mixing, the average thickness of coating drops between 20 to 30 μm.Adopt the diffusion barrier 13 that this material is formed, it is possible to there is the light transmittance of about 90%, it is however generally that, light transmittance range from about 85% to 96%.It addition, this diffusion barrier 13 is except having the effect of diffusion light, moreover it is possible to play the effect of electric isolution, so that when glass lamp breaks, reduce the risk that user gets an electric shock；Meanwhile, this diffusion barrier 13 so that light source 202 is when luminescence, can allow light produce diffusion, toward penetrating from all directions such that it is able to shine the rear of light source 202, namely near the side of bendable circuit soft board, avoid formation dark space, the illumination comfort of room for promotion in glass lamp 1.Additionally, when selecting the diffusion coating of different materials composition, have alternatively possible embodiment, it is possible to adopting diffusion barrier thickness range is 200 μm to 300 μm, and light transmittance controls between 92% to 94%, also has another kind of effect.
In other embodiments, diffusion coating can also calcium carbonate be main material, the reflecting material (such as strontium phosphate or barium sulfate) of arranging in pairs or groups a small amount of, thickening agent, ceramic active carbon and deionized water, being coated on after mixing on the inner peripheral surface of glass lamp, the average thickness of coating drops between 20 to 30 μm.Owing to the purpose of diffusion barrier is to allow light produce diffusion, diffusion phenomenon is at microcosmic, it it is the light reflection through granule, the grain diameter size of the reflecting material such as strontium phosphate or barium sulfate can much larger than the particle diameter of calcium carbonate, therefore, select in diffusion coating, add a small amount of reflecting material, can effectively increase the diffusion effect of light.
Certainly, in other embodiments, can also select calcium halophosphate activated by antimony andmanganese or aluminium oxide is the main material of diffusion coating, the particle diameter of the granule of calcium carbonate about drops between 2 to 4 μm, and the particle diameter of the granule of calcium halophosphate activated by antimony andmanganese and aluminium oxide about respectively falls between 4 to 6 μm and between 1 to 2 μm, for calcium carbonate, when the claimed range of light transmittance drops on 85% to 92%, the average thickness that the diffusion coating that entirety is main material with calcium carbonate need to be coated with is about 20 to 30 μm, under identical light transmittance requirement scope (85% to 92%), calcium halophosphate activated by antimony andmanganese is that the average thickness that the diffusion coating of main material need to be coated with can drop on 25 to 35 μm, aluminium oxide is that the average thickness that the diffusion coating of main material need to be coated with can drop on 10 to 15 μm.If light transmittance demand is higher, for instance more than 92%, then the diffusion coating thickness being main material with calcium carbonate, calcium halophosphate activated by antimony andmanganese or aluminium oxide then needs thinner.
It is to say, according to the use occasion of glass lamp 1, and select different light transmittance demands, i.e. optional formation thickness being intended to the main material of coating diffusion coating, correspondence etc..Need to remarking additionally, the light transmittance of diffusion barrier is more high, and user sees that the granular sensation of light source can be more significant.
With continued reference to Fig. 4, further, the inner peripheral surface of glass lamp 1 being additionally provided with reflectance coating 12, reflectance coating 12 is located to be had around the lamp plate 2 of light source 202, and circumferentially takies the part inner peripheral surface of glass lamp 1.As shown in Figure 4, reflectance coating 12 is circumferentially extending along glass lamp in lamp plate 2 both sides, and lamp plate 2 is generally within reflectance coating 12 centre position circumferentially.The setting of reflectance coating 12 has the effect of two aspects, on the one hand, when when from the side, (in figure X-direction) sees glass lamp 1, stops with reflectance coating 12, will not be immediately seen light source 202, thus reducing the visual discomfort that granular sensation causes；On the other hand, the light that light source 202 sends is through the reflection of reflectance coating 12, it is possible to control the angle of divergence of glass lamp so that light irradiates more towards the direction being not coated with reflectance coating, make LED straight lamp obtain identical radiation response with less power, improve energy saving.
Specifically, reflectance coating 12 is attached on the inner peripheral surface of glass lamp 1, and offers the perforate 12a corresponding with lamp plate 2 on reflectance coating 12, and the size of perforate 12a should be consistent with lamp plate 2 or slightly larger than lamp plate 2, for holding the lamp plate 2 with light source 202.During assembling, first the lamp plate 2 (or bendable circuit soft board) with light source 202 is arranged on the inner peripheral surface of glass lamp 1, reflectance coating 12 is sticked at glass lamp inner peripheral surface again, wherein the perforate 12a of reflectance coating 12 and lamp plate 2 one_to_one corresponding, outside lamp plate 2 is exposed to reflectance coating 12.
In one embodiment, the reflectance of reflectance coating 12 is at least greater than 85%, and reflecting effect is better, when being typically in more than 90%, it is therefore desirable to reach more than 95%, to obtain more preferably reflecting effect.Reflectance coating 12 occupies the 30% to 50% of whole glass lamp 1 circumference along the length that glass lamp 1 is circumferentially extending, that is, along the circumferential direction of glass lamp 1, the proportion between circumferential lengths and the girth of glass lamp 1 inner peripheral surface of reflectance coating 12 is 0.3 to 0.5.Spy gives explanation, and the present invention is only arranged on reflectance coating 12 medium position circumferentially for lamp plate 2, say, that lamp plate 2 both sides reflectance coating 12 has the area being substantially the same, as shown in Figure 4.The material of reflectance coating can be PET, strontium phosphate and barium sulfate any of which, or the wherein combination of wantonly two kinds, or the combination of three kinds, reflecting effect is better, thickness range, between 140 μm to 350 μm, is typically between 150 μm to 220 μm, and effect is more preferably.As it is shown in figure 5, in other embodiments, reflectance coating 12 can only be located at the side of lamp plate 2, i.e. reflectance coating 12 and the circumferential side contacts of lamp plate 2, and the ratio that its circumference one side occupies glass lamp 1 circumference is similarly 0.3 to 0.5.Or, as shown in Figure 6, Figure 7, reflectance coating 12 can not offer perforate, directly reflectance coating 12 is sticked on the inner peripheral surface of glass lamp 1 during assembling, then being fixed on reflectance coating 12 by the lamp plate 2 with light source 202 again, reflectance coating 12 can also be circumferentially extending along glass lamp respectively in the one or both sides of lamp plate 2 herein.
All kinds reflectance coating 12 described in the above-described embodiments and all kinds diffusion barrier 13 can arbitrarily be arranged in pairs or groups, and can realize individually reflection, individually the optical effect of diffusion or realization reflection simultaneously and diffusion.For example, it is possible to only arrange reflectance coating 12, it is not provided with diffusion barrier 13, as shown in Fig. 6, Fig. 7 and Fig. 8.
In other embodiments; the width of bendable circuit soft board can be widened, and owing to circuit board surface includes the circuit protecting layer of ink material, and ink material has the effect of reflection light; therefore at the position widened, circuit board itself just can play such as the effect of reflectance coating 12 function.Preferably, bendable circuit soft board is 0.3 to 0.5 along the proportion between circumferentially extending length and the girth of described glass lamp 2 inner peripheral surface of glass lamp 2.A circuit protecting layer can be coated with outside bendable circuit soft board; circuit protecting layer can be a kind of ink material; having the function increasing reflection, the bendable circuit soft board widened is with light source for starting point to circumferentially extending, and the light of light source can make light more concentrate by the position widened.
In other examples, on the inner peripheral surface of glass tubing, can all coat diffusion coating, or partly coat diffusion coating (having reflectance coating 12 part not to be coated with), but no matter it is any mode, diffusion coating to be preferably both coated onto on the outer surface of end region of glass lamp 1, so that the gluing between lamp holder 3 and glass lamp 1 is more firm.
Need to supplement, in the above embodiment of the present invention, all can be selected for the one in the group being made up of diffusion coating, diffusion barrier sheet, reflectance coating and adhesive film, be applied to the optical treatment of light source emitted light of the present invention.
Continuing referring to Fig. 2, in one embodiment of the invention, LED straight lamp also includes bonding agent sheet 4, lamp plate insulation film 7 and light source film 8.Lamp plate 2 is pasted on the inner peripheral surface of glass lamp 1 by bonding agent sheet 4.Shown in figure, bonding agent sheet 4 can be silica gel, and its form is not limit, it is possible to be several sections shown in figure, or a section in strip.Various forms of bonding agent sheets 4, various forms of lamp plate insulation film 7 and various forms of light source film 8 can combine each other and constitute the difference embodiment of the present invention.
Lamp plate insulation film 7 is applied to lamp plate 2 on the surface of light source 202 so that lamp plate 2 does not expose, thus playing the insulating effect being isolated from the outside by lamp plate 2.Reserving the through hole 71 corresponding with light source 202 during gluing, light source 202 is located in through hole 71.The constituent of lamp plate insulation film 7 includes vinyl polysiloxane, hydrogen-based polysiloxanes and aluminium oxide.The thickness range of lamp plate insulation film 7 is 100 μm to 140 μm (micron).If less than 100 μm, then do not have enough insulating effects, if greater than 140 μm, then can cause the waste of material.
Light source film 8 is applied to the surface of light source 202.The color of light source film 8 is transparent color, to ensure light transmittance.Coating is to light source 202 surface, and the shape of light source film 8 can be graininess, strip or lamellar.Wherein, the parameter of light source film 8 has refractive index, thickness etc..What the refractive index of light source film 8 allowed ranges for 1.22～1.6, if the radical sign of opening that the refractive index of light source film 8 is light source 202 housing refractive index, or the refractive index of light source film 8 be light source 202 housing refractive index open positive and negative the 15% of radical sign, then light transmittance is better.Here light source shell refers to the housing holding LED grain (or chip).In the present embodiment, the ranges of indices of refraction of light source film 8 is 1.225 to 1.253.The thickness range that light source film 8 allows is 1.1mm to 1.3mm, if less than 1.1mm, it will lid is light source 202 incessantly, and poor effect if greater than 1.3mm, then can reduce light transmittance, also can increase material cost simultaneously.
During assembling, first light source film 8 is applied to the surface of light source 202；Then the film 7 that insulated by lamp plate is applied on the side surface on lamp plate 2；Again light source 202 is fixed on lamp plate 2；Then a side surface opposing to lamp plate 2 and light source 202 is pasted by bonding agent sheet 4 inner peripheral surface being fixed on glass lamp 1；The last end region that lamp holder 3 is fixed on glass lamp 1 again, electrically connects light source 202 with power supply 5 simultaneously.Or as it is shown in figure 9, utilize bendable circuit soft board 2 to weld through a freedom portion 21 and power supply 5, or take the mode of conventional wires routing to allow lamp plate 2 and power supply 5 be electrical connected, form a complete LED straight lamp.
In the present embodiment, lamp plate 2 is fixed on the inner peripheral surface of glass lamp 1 by bonding agent sheet 4 so that lamp plate 2 is sticked on the inner peripheral surface of glass lamp 1, so can increase the lighting angle of whole LED straight lamp, expanding angle of visibility, so arranging generally can so that angle of visibility can more than 330 degree.By being coated with lamp plate insulation film 7 at lamp plate 2, light source 202 being coated with the light source film 8 of insulation, it is achieved the insulation processing to whole lamp plate 2, such that make glass lamp 1 break, without there is electric shock accidents, improving safety.
Further, glass lamp 1 inner peripheral surface or outer peripheral face can be coated with adhesive film (not shown), for outwardly and inwardly isolating glass lamp 1 after glass lamp 1 breaks.Adhesive film is coated on the inner peripheral surface of glass lamp 1 by the present embodiment.
The constituent of adhesive film includes vinyl-terminated silicone fluid, containing hydrogen silicone oil, dimethylbenzene and calcium carbonate.Wherein dimethylbenzene is auxiliary agents, and after adhesive film is coated in glass lamp 1 inner peripheral surface and solidifies, dimethylbenzene can vapor away, and its effect mainly regulates viscosity, and then regulates the thickness of adhesive film.
In one embodiment, the thickness range of adhesive film is 100 μm to 140 μm.If adhesive film thickness is less than 100 μm, explosion-proof performance is inadequate, and during glass breaking, whole glass lamp can split, and then can reduce light transmittance more than 140 μm, and increase material cost.If explosion-proof performance and light transmittance requirement are relatively loose, then the thickness range of adhesive film can also be relaxed to 10 μm to 800 μm.
In the present embodiment, owing to scribbling adhesive film inside glass lamp, after glass glass fluorescent tube is broken, adhesive film can by fragment adhesion together, and the through hole that through glass lamp is inside and outside will not be formed, thus preventing user from touching the electrical body within glass lamp 1, to avoid electric shock accidents, the adhesive film simultaneously adopting said ratio also has the effect of diffusion light, printing opacity, improves Luminescence Uniformity and the light transmittance of whole LED straight lamp.The adhesive film of the present embodiment can use with aforesaid bonding agent sheet 4, lamp plate insulation film 7 and light source film 8 collocation, and constitutes the various different embodiments of the present invention.It should be noted that when lamp plate 2 is bendable circuit soft board, it is also possible to be not provided with adhesive film.
Further, the lamp plate 2 of the present embodiment adopts bendable circuit soft board, so after glass lamp 1 breaks, namely cannot support the glass lamp 1 broken and continue to remain straight tube state, to inform that user LED straight lamp can not use, it is to avoid the generation of electric shock accidents.Therefore, after adopting bendable circuit soft board, it is possible to alleviate electric shock problem that is broken due to glass tubing and that cause to a certain extent.Described lamp plate 2 is a bendable circuit soft board and is a single layer patterning metallic circuit Rotating fields or the single layer patterning metallic circuit layer double-decker of adding one dielectric layer.
Refer to Figure 10, in one embodiment, bendable circuit soft board as lamp plate 2 includes one layer of single layer patterning metallic circuit layer 2a with conductive effect, and light source 202 is located on single layer patterning metallic circuit layer 2a, is connected with power sourced electric by single layer patterning metallic circuit layer 2a.With reference to Figure 10, in the present embodiment, bendable circuit soft board can also include one dielectric layer 2b, overlapped with single layer patterning metallic circuit layer 2a, the area equation of dielectric layer 2b and single layer patterning metallic circuit layer 2a, single layer patterning metallic circuit layer 2a is used for arranging light source 202 on the surface opposing with dielectric layer 2b.Single layer patterning metallic circuit layer 2a is electrically connected to power supply 5 in order to allow DC current pass through.Dielectric layer 2b is then being adhered on the inner peripheral surface of glass lamp 1 by bonding agent sheet 4 with single layer patterning surface opposing for metallic circuit layer 2a.
In other embodiments, the outer surface of single layer patterning metallic circuit layer 2a and dielectric layer 2b can be coated with a circuit protecting layer, and described circuit protecting layer can be a kind of ink material, has welding resistance and increases the function of reflection.Or, bendable circuit soft board can be a Rotating fields, is namely only made up of one layer of single layer patterning metallic circuit layer 2a, and then the surface at single layer patterning metallic circuit layer 2a can be the circuit protecting layer of one layer of above-mentioned ink material of cladding or not have.Whether one layer of single layer patterning metallic circuit layer 2a structure or two-layer structure (one layer of single layer patterning metallic circuit layer 2a and one dielectric layer 2b) can coupled circuit protective layers.Circuit protecting layer can also in the side surface configuration of bendable circuit soft board, for instance only arrange circuit protecting layer in the side with light source 202.It should be noted that, bendable circuit soft board is one layer of single layer patterning metallic circuit Rotating fields 2a or is two-layer structure (one layer of single layer patterning metallic circuit layer 2a and one dielectric layer 2b), substantially ratio general three layers flexible base board (pressing from both sides one dielectric layer in two sandwich circuit layers) more pliability and flexibility, therefore, can arrange in pairs or groups (such as: non-straight lamp) with having special formed glass lamp 1, and bendable circuit soft board is close on glass lamp 1 tube wall.Additionally, bendable circuit soft board is close to glass lamp tube wall for preferably to configure, and the number of plies of bendable circuit soft board is more few, then radiating effect is more good, and material cost is more low, more environmental protection, and pliable and tough effect also has an opportunity to promote.
In other embodiments, as the length of the bendable circuit soft board of lamp plate 2 length more than glass lamp.
Continuing referring to Fig. 2, lamp plate 2 is provided with some light sources 202, is provided with power supply 5 in lamp holder 3, by lamp plate 2 electrical communication between light source 202 and power supply 5.In various embodiments of the present invention, power supply 5 can be single body (namely all power supply modules are all integrated in parts), and is located in the lamp holder 3 of glass lamp 1 one end；Or power supply 5 can also be divided into two parts, it is called double; two individual (namely all power supply modules are separately positioned in two parts), and two parts is respectively arranged in the lamp holder 3 at glass lamp two ends.
No matter it is single body or double; two individuality, the generation type of power supply can have Mutiple Choice, such as, power supply can be the module after a kind of embedding molding, specifically, uses the silica gel (heat conductivity >=0.7w/m k) of a kind of high heat conduction, by mould, power supply module is carried out embedding molding, obtain power supply, the advantage that the power supply that this mode obtains has high insulation, height dispels the heat, profile is more regular, and can coordinate with other structural members easily.Or, exposed power supply module for not do casting glue molding, directly can also be inserted inside lamp holder by power supply, or after the exposed power supply module conventional thermal draw is encased, then it is internal to insert lamp holder 3.In other words, in various embodiments of the present invention, power supply 5 can be the form appearance carrying power supply module as shown in Figure 9 with monolithic printed circuit board (PCB), also can be occur with the form of single module as shown in figure 25.
Refer to Fig. 2 and in conjunction with Figure 25, in an embodiment, one end of power supply 5 has male plug 51, and the other end has metal ferrule 52, and the end of lamp plate 2 is provided with female plug 201, and lamp holder 3 is provided with the hollow conductive pin 301 for connecting external power source.The male plug 51 of power supply 5 is inserted in the female plug 201 of lamp plate 2, and metal ferrule 52 is inserted in the hollow conductive pin 301 of lamp holder 3.Now male plug 51 and female plug 201 are equivalent to adaptor, for power supply 5 and lamp plate 2 being electrically connected.When metal ferrule 52 inserts after in hollow conductive pin 301, impact hollow conductive pin 301 through outside stamping tool so that slight deformation occurs hollow conductive pin 301, thus the metal ferrule 52 fixed on power supply 5, and realize electrical connection.During energising, electric current passes sequentially through hollow conductive pin 301, metal ferrule 52, male plug 51 and female plug 201 and arrives lamp plate 2, and arrives light source 202 by lamp plate 2.But, the structure of power supply 5 is then not limited to modular pattern shown in Figure 25.Power supply 5 can be a printed circuit board (PCB) being loaded with power supply module, then is electrically connected with connected mode and the lamp plate 2 of male plug 51, female plug 201.Vice versa for it, can be that one end of power supply has female plug in another embodiment, and the end of lamp plate is provided with male plug, and power supply is electrically connected with lamp plate by the connected mode of female plug, male plug again.
In other embodiments, electric connection between power supply 5 and the lamp plate 2 of any pattern can also replace above-mentioned male plug 51 and female plug 201 by conventional wires routing mode, namely adopting a traditional plain conductor, electrically connected with power supply one end of plain conductor, the other end electrically connects with lamp plate 2.Further, plain conductor can be coated with an insulated sleeve to protect user to avoid getting an electric shock.But the mode that wire routing connects likely has the problem of fracture in transportation, slightly worse in quality.
In other embodiments, the electric connection between power supply 5 with lamp plate 2 can by rivet nail joint, tin cream gluing, weld or by wire binding in the way of be directly linked together.Consistent with the fixed form of aforementioned lamp plate 2, a side surface of bendable circuit soft board is bonded and fixed to the inner peripheral surface of glass lamp 1 by bonding agent sheet 4, and the two ends of bendable circuit soft board can select fixing or not be fixed on the inner peripheral surface of glass lamp 1.
If the two ends of bendable circuit soft board are fixed on the inner peripheral surface of glass lamp 1, then pay the utmost attention to and female plug 201 is set on bendable circuit soft board, then the male plug 51 of power supply 5 is inserted female plug 201 and realizes electrical connection.
If lamp plate 2 is not fixed on the inner peripheral surface of glass lamp 1 along the two ends that glass lamp 1 is axial, if adopting wire to connect, move in process follow-up, due to two ends freely, process is susceptible to rock in follow-up moving, thus makes it possible to wire and rupture.Therefore lamp plate 2 with the connected mode prioritizing selection of power supply 5 for welding.Specifically, with reference to Fig. 9, it is possible to be welded on the outfan of power supply 5 after directly being got over by lamp plate 2, remove the use of wire from, improve the stability of product quality.Now lamp plate 2 need not arrange female plug 201, and the outfan of power supply 5 is also without arranging male plug 51.
As shown in figure 11, the concrete practice can be that the outfan of power supply 5 is reserved power pad a, and on power pad a, stay stannum so that the thickness of stannum on pad increases, convenient welding, accordingly, the end of lamp plate 2 also reserves light source pad b, and the light source pad b of the power pad a of power supply 5 outfan Yu lamp plate 2 is welded together.It is front by the plane definition at pad place, then lamp plate 2 docks the most firm with the connected mode of power supply 5 with the pad in both fronts, but welding pressure head must be pressed in the back side of lamp plate 2 when welding, scolding tin is heated across lamp plate 2, the problem being easier reliability occurs.If as shown in figure 17, will output hole in the middle of the light source pad b in lamp plate 2 front, then the superposition that faced up welds on the power pad a in power supply 5 front, then scolding tin heating can directly be melted by welding pressure head, to being relatively easy on Practical Operation realize.
As shown in figure 11, in above-described embodiment, bendable circuit soft board major part as lamp plate 2 is fixed on the inner peripheral surface of glass lamp 1, it is be not only fixed on the inner peripheral surface of glass lamp 1 at two ends, the lamp plate 2 not being fixed on glass lamp 1 inner peripheral surface forms a freedom portion 21, and lamp plate 2 is fixed on the inner peripheral surface of glass lamp 1.Freedom portion 21 has above-mentioned pad b.When assembling, one end of freedom portion 21 and power supply 5 welding can drive freedom portion 21 to glass lamp 1 internal contraction.Bendable circuit soft board as lamp plate 2 can not also possess freedom portion and pass through a single layer patterning metallic circuit Rotating fields or a single layer patterning metallic circuit layer is added the double-decker of one dielectric layer and is directly electrically connected with power supply 5.In the present embodiment, when lamp plate 2 and power supply 5 connect, the surface, light source 202 place on pad b and a and lamp plate in the same direction, and is formed with through hole e as shown in figure 17 on the pad b on lamp plate 2 so that pad b and pad a is interconnected.When the freedom portion 21 of lamp plate 2 deforms towards the internal contraction of glass lamp 1, power supply 5 is had a lateral pulling force by the welded connection between printed circuit board (PCB) and the lamp plate 2 of power supply 5.Further, compared to the aspectant situation of pad b system on the pad a of power supply 5 and lamp plate 2, power supply 5 is also had a downward pulling force by the welded connection between printed circuit board (PCB) and the lamp plate 2 of power supply 5 here.This downward pulling force comes from the solder in through hole e and forms one between power supply 5 and lamp plate 2 and more strengthen and be firmly electrically connected.
As shown in figure 12, the light source pad b of lamp plate 2 is two unconnected pads, electrically connects with light source 202 both positive and negative polarity respectively, and the size of pad is about 3.5 × 2mm2, the printed circuit board (PCB) of power supply 5 also has pad corresponding thereto, being arranged above of pad is easy to welding board automatic welding and is had reserved stannum, and the thickness of stannum can be 0.1 to 0.7mm, it is advantageous to value is that 0.3 to 0.5mm is comparatively appropriate, with 0.4mm for the best.One insulation hole c can be set between two pads, two pads are avoided to cause electrical short in the process of welding because scolding tin is welded together, the rear of this external insulated hole hole c also can arrange location hole d, is used for the tram allowing automatic welding board can correctly judge light source pad b.
The light source pad b of lamp plate has at least one, electrically connects with light source 202 both positive and negative polarity respectively.In other embodiments, in order to be able to reach the extendibility in compatible and follow-up use, the quantity of light source pad b can have more than one, for instance 2,3,4 or more than 4.When pad only has 1, corresponding two ends of lamp plate all can electrically connect with power supply respectively, to form primary Ioops, and the mode that now available electronic building brick replaces, for instance: replace electric capacity with inductance and be used as current stabilization assembly.If Figure 13 is to shown in 17, when pad is 3, the 3rd pad can serve as ground connection and use, and when pad is 4, the 4th pad can be used to make signal input end.Accordingly, power pad a is also identical with light source pad b quantity.When pad is more than 3, the arrangement between pad side by side or can line up two row for string, configuring in position according to accommodating size time actually used, causing short circuit as long as not electrically connecting each other.In other embodiments, if by part circuit production on bendable circuit soft board, light source pad b can be independent one, and number of pads is fewer, more saves flow process in technique；The more, the electrical connection of bendable circuit soft board and power output end is fixing more to be strengthened number of pads.
As shown in figure 17, in other embodiments, the inside of light source pad b can have the structure of welding perforation e, and the diameter of welding perforation e can be 1 to 2mm, it is advantageous to being 1.2 to 1.8mm, the best is 1.5mm, too little, and the stannum welded not easily passes through.When the power pad a of the power supply 5 and light source pad b of lamp plate 2 welds together, the stannum of welding can pass described welding perforation e, then it is deposited in cooling above welding perforation e to condense, form the ball structure g having more than welding perforation e diameter, it seems the function of nail that this ball structure g can play, except fixing through the stannum between power pad a and light source pad b, more can strengthen the firm fixed of electric connection because of the effect of ball structure g.
As shown in Figure 18 to Figure 19, in other embodiments, as the edge 1mm of the welding perforation e distance lamp plate 2 of light source pad b, the stannum of welding can pass described hole e and be deposited in hole top edges, too much stannum also can reflux from the edge of lamp plate 2 toward lower section, then, together with condensing in the stannum on power pad a, its structure similarly is that lamp plate 2 is followed closely on the circuit board of power supply 5 by a rivet firmly, has reliable electricity connection function.As shown in Figure 20 and Figure 21, in other embodiments, welding breach f instead of welding perforation e, the welding perforation of pad is at edge, the stannum of welding electrically connects power pad a and light source pad b fixing through described welding breach f, stannum is easier to climb up light source pad b and is deposited in around welding breach f, forms, when cooling has more stannum after condensing, the soldered ball having more than welding breach f diameter, and this ball structure can allow the crystallized ability of electric connection structure strengthen.In the present embodiment, because the design of welding breach, it seems the sub function of C staple that the stannum of welding plays.
