With reference to Fig. 4, in the glass lamp of the present embodiment 1, except being close to the lamp plate 2 (or bendable circuit soft board) of glass lamp 1, also comprises diffusion barrier 13, the light that light source 202 produces passes glass lamp 1 after by diffusion barrier 13. The light that diffusion barrier 13 sends light source 202 plays the effect of diffusion, therefore, as long as pass again glass lamp 1 after making light see through diffusion barrier 13, the layout of diffusion barrier 13 can have various ways, for example: diffusion barrier 13 can apply or be covered on the inner peripheral surface of glass lamp 1, or be coated on the lip-deep diffusion coating (not shown) of light source 202, or cover (or covering) diffusion barrier sheet outside light source 202 as an outer cover.

Please, referring again to Fig. 4, in the time that 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, conventionally with the diffusion particle of arranging in pairs or groups of one or more the combination in PS polystyrene, PMMA polymethyl methacrylate, PET (PET), PC (Merlon), a kind of composite forming, in the time that light sees through this composite, can there is diffusion phenomenon, can revise light and become uniform area light source finally to make to be uniformly distributed from the brightness of glass lamp with the effect that reaches optics diffusion.

In the time that diffusion barrier 13 is diffusion coating, its main component can be wherein any of calcium carbonate, calcium halophosphate activated by antimony andmanganese and aluminium oxide, or the wherein combination of wantonly two kinds, or the combination of three kinds. When the diffusion coating that utilizes calcium carbonate to form for the solution that it is suitable that main material is arranged in pairs or groups, the effect of excellent diffusion and printing opacity (having an opportunity to reach more than 90%) will be there is.

In the present embodiment, in the time of allotment, the constituent of diffusion coating comprises calcium carbonate, strontium phosphate (for example CMS-5000, white powder), thickener, and ceramic active carbon (for example ceramic activated carbon SW-C, colourless liquid). Particularly, when diffusion coating is taking calcium carbonate as main material, collocation thickener, ceramic activated carbon and deionized water, be coated on after mixing on the inner peripheral surface of glass glass lamp, and the average thickness of coating drops between 20 to 30 μ m. The diffusion barrier 13 that adopts this material to form, can have approximately 90% light transmittance, and generally speaking, the scope of light transmittance is about 85% to 96%. In addition, this diffusion barrier 13, except the effect with diffused light, can also play the effect of electricity isolation, thereby make in the time that glass lamp breaks, and reduces the risk that user gets an electric shock; Meanwhile, this diffusion barrier 13 can make light source 202 when luminous, allows light produce diffusion, toward penetrating, thereby can shine the rear of light source 202 from all directions, near a side of bendable circuit soft board, avoid forming dark space in glass lamp 1 the illumination comfort of room for promotion. In addition, in the time selecting the diffusion coating of different materials composition, have another kind of possible embodiment, can adopt diffusion barrier thickness range is 200 μ m to 300 μ m, and light transmittance is controlled between 92% to 94%, also has another kind of effect.

In other embodiments, diffusion coating can calcium carbonate be also main material, arrange in pairs or groups a small amount of reflecting material (as strontium phosphate or barium sulfate), thickener, pottery activated carbon and deionized water, after mixing, be coated on the inner peripheral surface of glass lamp, the average thickness of coating drops between 20 to 30 μ m. Because the object of diffusion barrier is to allow light produce diffusion, diffusion phenomenon is at microcosmic, the reflex of light through particle, the grain diameter size of the reflecting material such as strontium phosphate or barium sulfate can be much larger than the particle diameter of calcium carbonate, therefore, be chosen in diffusion coating and add a small amount of reflecting material, can effectively increase the diffusion effect of light.

Certainly, in other embodiment, also can select calcium halophosphate activated by antimony andmanganese or aluminium oxide is the main material of diffusion coating, the particle diameter of the particle of calcium carbonate approximately drops between 2 to 4 μ m, and the particle diameter of the particle of calcium halophosphate activated by antimony andmanganese and aluminium oxide drops on approximately respectively between 4 to 6 μ m and between 1 to 2 μ m, taking calcium carbonate as example, in the time that the claimed range of light transmittance drops on 85% to 92%, the average thickness that the diffusion coating of entirety taking calcium carbonate as main material need apply is about 20 to 30 μ m, 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 apply can drop on 25 to 35 μ m, aluminium oxide is that the average thickness that the diffusion coating of main material need apply can drop on 10 to 15 μ m. if when light transmittance demand is higher, for example more than 92%, the diffusion coating thickness taking calcium carbonate, calcium halophosphate activated by antimony andmanganese or aluminium oxide as main material needs thinner.

That is to say, according to the use occasion of glass lamp 1, and select different light transmittance demands, can select institute's wish to apply the main material of diffusion coating, corresponding formation thickness etc. Need supplementary notes, the light transmittance of diffusion barrier is higher, and user sees that the granular sensation of light source can more show.

Continue with reference to Fig. 4, further, be also provided with reflectance coating 12 on the inner peripheral surface of glass lamp 1, reflectance coating 12 is located at around the lamp plate 2 with light source 202, and along the part inner peripheral surface that circumferentially takies glass lamp 1. As shown in Figure 4, reflectance coating 12 circumferentially extends along glass lamp in lamp plate 2 both sides, and lamp plate 2 is positioned at reflectance coating 12 substantially along circumferential centre position. The setting of reflectance coating 12 has the effect of two aspects, on the one hand, when (directions X in figure) sees glass lamp 1 when from the side, owing to there being reflectance coating 12 to stop, can directly not see light source 202, thereby reduces the visual discomfort that granular sensation causes; On the other hand, the light that light source 202 sends, through the reflex of reflectance coating 12, can be controlled the angle of divergence of glass lamp, and light is irradiated towards the direction that does not scribble reflectance coating more, make LED straight lamp obtain identical radiation response with lower power, improve energy saving.

Particularly, reflectance coating 12 is attached on the inner peripheral surface of glass lamp 1, and on reflectance coating 12, offers the perforate 12a corresponding with lamp plate 2, and the size of perforate 12a should be consistent with lamp plate 2 or be slightly larger than lamp plate 2, for holding the lamp plate 2 with light source 202. When assembling, first the lamp plate with light source 202 2 (or bendable circuit soft board) is arranged on the inner peripheral surface of glass lamp 1, again reflectance coating 12 is sticked at glass lamp inner peripheral surface, wherein the perforate 12a of reflectance coating 12 is corresponding one by one with lamp plate 2, so that lamp plate 2 is exposed to outside reflectance coating 12.

In one embodiment, the reflectivity of reflectance coating 12 is at least greater than 85%, and reflecting effect is better, generally, preferably can reach more than 95%, to obtain more preferably reflecting effect when above 90%. The length that reflectance coating 12 circumferentially extends along glass lamp 1 occupies 30% to 50% of whole glass lamp 1 circumference, that is to say, along the circumferential direction of glass lamp 1, the proportion between the circumferential lengths of reflectance coating 12 and the girth of glass lamp 1 inner peripheral surface is 0.3 to 0.5. Spy gives explanation, and the present invention is only arranged on reflectance coating 12 along circumferential medium position as example taking lamp plate 2, that is to say, lamp plate 2 both sides reflectance coatings 12 have identical in fact area, as shown in Figure 4. The material of reflectance coating can be PET, strontium phosphate and barium sulfate wherein any, or the wherein combination of wantonly two kinds, or the combination of three kinds, reflecting effect is better, thickness range is between 140 μ m to 350 μ m, and generally, between 150 μ m to 220 μ m, effect is better. As shown in Figure 5, in other embodiments, reflectance coating 12 can be only located at a side of lamp plate 2, i.e. the circumferential side contacts of reflectance coating 12 and lamp plate 2, and its circumferential one-sided ratio that 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 offered perforate, when assembling, directly reflectance coating 12 is sticked on the inner peripheral surface of glass lamp 1, and then the lamp plate with light source 202 2 is fixed on reflectance coating 12, reflectance coating 12 also can circumferentially extend along glass lamp respectively in the one or both sides of lamp plate 2 herein.

Described all kinds reflectance coating 12 can be arranged in pairs or groups arbitrarily with all kinds diffusion barrier 13 in the above-described embodiments, and can realize reflection separately, spreads separately or realize simultaneously the optical effect of reflection and diffusion. For example, reflectance coating 12 can be only set, diffusion barrier 13 be set, as shown in Fig. 6, Fig. 7 and Fig. 8.

In other embodiments; the width of bendable circuit soft board can be widened, and because circuit board surface comprises the circuit protecting layer of ink material, and ink material has the effect of reflection ray; therefore at the position of widening, just circuit board itself can play as the effect of reflectance coating 12 functions. Preferably, the proportion between bendable circuit soft board circumferentially extends along glass lamp 2 length and the girth of described glass lamp 2 inner peripheral surfaces is 0.3 to 0.5. Bendable circuit soft board is outer can be coated a circuit protecting layer; circuit protecting layer can be a kind of ink material; have the function that increases reflection, the bendable circuit soft board of widening is taking light source as starting point to circumferential extension, and the light of light source can make light more concentrated by the position of widening.

In other embodiment, on the inner peripheral surface of glass tube, can all coat diffusion coating, or part is coated diffusion coating (having reflectance coating 12 parts not to be coated with), but no matter be any mode, diffusion coating preferably all will be coated onto on the outer surface of end region of glass lamp 1, to make the gluing between lamp holder 3 and glass lamp 1 more firm.

Need to supplement, in the above embodiment of the present invention, all can select by the one in diffusion coating, diffusion barrier sheet, reflectance coating and group that adhesive film formed, be applied to the optical treatment of light source emitted light of the present invention.

Continue referring to Fig. 2, in one embodiment of the invention, LED straight lamp also comprises 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, and can be several sections shown in figure, or is a section of 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 form the present invention's different embodiment.

Lamp plate insulation film 7 is applied to lamp plate 2 on the surface of light source 202, lamp plate 2 is not exposed, thereby play the insulating effect that lamp plate 2 is isolated from the outside. When gluing, reserve the through hole corresponding with light source 202 71, light source 202 is located in through hole 71. The constituent of lamp plate insulation film 7 comprises vinyl polysiloxanes, hydrogen based polysiloxane and aluminium oxide. The thickness range of lamp plate insulation film 7 is 100 μ m to 140 μ m (micron). If be less than 100 μ m, do not have enough insulating effects, if be greater than 140 μ m, 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. Be coated to behind light source 202 surfaces, the shape of light source film 8 can be graininess, strip or sheet. Wherein, the parameter of light source film 8 has refractive index, thickness etc. The scope that the refractive index of light source film 8 allows is 1.22～1.6, if the refractive index of light source film 8 is the radical sign of opening of light source 202 housing refractive indexes, or the refractive index of light source film 8 be light source 202 housing refractive indexes open the positive and negative 15% of radical sign, light transmittance is better. The light source shell here refers to the housing that holds LED crystal 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 be less than 1.1mm, will cover incessantly light source 202, and poor effect, if be greater than 1.3mm, can reduce light transmittance, also can increase material cost simultaneously.

When assembling, first light source film 8 is applied to the surface of light source 202; Then the film 7 that lamp plate insulated 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 to the inner peripheral surface that is fixed on glass lamp 1 by bonding agent sheet 4; The last end region of again lamp holder 3 being fixed on to glass lamp 1 is electrically connected light source 202 simultaneously with power supply 5. Or as shown in Figure 9, utilize bendable circuit soft board 2 to weld through a free 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, lamp plate 2 is sticked on the inner peripheral surface of glass lamp 1, can increase like this lighting angle of whole LED straight lamp, expand angle of visibility, arrange like this and generally can make angle of visibility can exceed 330 degree. By be coated with lamp plate insulation film 7 at lamp plate 2, on light source 202, be coated with the light source film 8 of insulation, realize the insulation processing to whole lamp plate 2, like this, even if glass lamp 1 breaks, can there is not electric shock accidents yet, improve security.

Further, on glass lamp 1 inner peripheral surface or outer peripheral face, can be coated with adhesive film (not shown), isolate for outside and the inside to glass lamp 1 after breaking at glass lamp 1. The present embodiment is coated in adhesive film on the inner peripheral surface of glass lamp 1.

The constituent of adhesive film comprises vinyl-terminated silicone fluid, containing hydrogen silicone oil, dimethylbenzene and calcium carbonate. Wherein dimethylbenzene is complementary material, and after adhesive film is coated in glass lamp 1 inner peripheral surface and solidifies, dimethylbenzene can vapor away, and its effect is mainly adjusting viscosity, and then regulates the thickness of adhesive film.

In one embodiment, the thickness range of adhesive film is 100 μ m to 140 μ m. If adhesive film thickness is less than 100 μ m, explosion-proof performance is inadequate, and when glass breaking, whole glass lamp can split, and is greater than 140 μ m and can reduces light transmittance, and increase material cost. If explosion-proof performance and light transmittance requirement are looser, the thickness range of adhesive film also can relax to 10 μ m to 800 μ m.

In the present embodiment, because glass lamp inside scribbles adhesive film, after the fragmentation of glass glass lamp, adhesive film can be by fragment adhesion together, and can not form and connect the inside and outside through hole of glass lamp, thereby prevent that user from touching the electrical body of glass lamp 1 inside, to avoid occurring electric shock accidents, adopt the adhesive film of said ratio also to there is the effect of diffused light, printing opacity simultaneously, improve 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 8 collocation of light source film, and forms various different embodiment of the present invention. It should be noted that when lamp plate 2 is for bendable circuit soft board, adhesive film also can be set.

Further, the lamp plate 2 of the present embodiment adopts bendable circuit soft board, after glass lamp 1 breaks, cannot support the glass lamp 1 breaking and continue to remain straight tube state like this, to inform that user LED straight lamp can not use, and avoids the generation of electric shock accidents. Therefore,, when adopting after bendable circuit soft board, can alleviate to a certain extent due to the broken electric shock problem causing of glass tube. Described lamp plate 2 is a bendable circuit soft board and is the double-decker that a single layer pattern metallic circuit layer structure or a single layer pattern metallic circuit layer are added one dielectric layer.

Please refer to Figure 10, in one embodiment, comprise that as the bendable circuit soft board of lamp plate 2 one deck has the single layer pattern metallic circuit layer 2a of conductive effect, it is upper that light source 202 is located at single layer pattern metallic circuit layer 2a, and by single layer pattern metallic circuit layer, 2a is communicated with power sourced electric. With reference to Figure 10, in the present embodiment, bendable circuit soft board can also comprise one dielectric layer 2b, 2a is overlapped with single layer pattern metallic circuit layer, dielectric layer 2b equates with the area of single layer pattern metallic circuit layer 2a, and single layer pattern metallic circuit layer 2a is being used for arranging light source 202 with the opposing surface of dielectric layer 2b. Single layer pattern metallic circuit layer 2a is electrically connected to power supply 5 in order to allow DC current pass through. Dielectric layer 2b is being adhered on the inner peripheral surface of glass lamp 1 by bonding agent sheet 4 with the opposing surface of single layer pattern metallic circuit layer 2a.

In other embodiments, the outer surface of single layer pattern metallic circuit layer 2a and dielectric layer 2b can be coated a circuit protecting layer, and described circuit protecting layer can be a kind of ink material, has welding resistance and increases the function reflecting. Or bendable circuit soft board can be one deck structure, only formed by one deck single layer pattern metallic circuit layer 2a, can be then coated the circuit protecting layer of the above-mentioned ink material of one deck or do not have on the surface of single layer pattern metallic circuit layer 2a. No matter be that one deck single layer pattern metallic circuit layer 2a structure or two-layer structure (one deck single layer pattern metallic circuit layer 2a and one dielectric layer 2b) can coupled circuit protective layers. Circuit protecting layer also can be in a side surface setting of bendable circuit soft board, for example, only circuit protecting layer is set having one of light source 202 side. It should be noted that, bendable circuit soft board is one deck single layer pattern metallic circuit layer structure 2a or is two-layer structure (one deck single layer pattern metallic circuit layer 2a and one dielectric layer 2b), obviously have more pliability and flexibility than three layers of general flexible base, board (pressing from both sides one dielectric layer in two sandwich circuit layers), therefore, can arrange in pairs or groups (for example: non-straight lamp) with thering is special formed glass lamp 1, and bendable circuit soft board is close on glass lamp 1 tube wall. In addition, bendable circuit soft board is close to glass lamp tube wall for preferably configuration, and the number of plies of bendable circuit soft board is fewer, and radiating effect is better, and material cost is lower, more environmental protection, and pliable and tough effect also has an opportunity to promote.

In other embodiments, be greater than the length of glass lamp as the length of the bendable circuit soft board of lamp plate 2.

Continue referring to Fig. 2, lamp plate 2 is provided with some light sources 202, is provided with power supply 5 in lamp holder 3, passes through 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 (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 also can be divided into two parts, be called two individual (all power supply modules are separately positioned in two parts), and two parts be located at respectively in the lamp holder 3 at glass lamp two ends.

No matter be single body or two individuality, the generation type of power supply can have Mutiple Choice, for example, power supply can be the module after a kind of embedding moulding, particularly, uses a kind of silica gel (thermal conductivity factor >=0.7w/mk) of high heat conduction, by mould, power supply module is carried out to embedding moulding, obtain power supply, the power supply that this mode obtains has advantages of that high insulation, height dispel the heat, profile is more regular, and can coordinate with other structural members easily. Or power supply also can, for not doing casting glue moulding, directly be inserted lamp holder inside by exposed power supply module, or after exposed power supply module is encased with traditional heat-shrink tube, then insert lamp holder 3 inside. In other words, in various embodiments of the present invention, power supply 5 can be the form appearance of carrying as shown in Figure 9 power supply module with monolithic printed circuit board (PCB), and the form with single module as shown in figure 25 that also can be occurs.

Please refer to Fig. 2 and in conjunction with Figure 25, in an embodiment, one end of power supply 5 has male plug 51, 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 adapter, for power supply 5 and lamp plate 2 are electrically connected. When metal ferrule 52 insert hollow conductive pin 301 interior after, impact hollow conductive pin 301 through outside stamping tool, make hollow conductive pin 301 that slight distortion occur, thereby fix the metal ferrule 52 on power supply 5, and realize electrical connection. When energising, electric current arrives lamp plate 2 by hollow conductive pin 301, metal ferrule 52, male plug 51 and female plug 201 successively, and arrives light source 202 by lamp plate 2. But the structure of power supply 5 is not limited to modular sample state shown in Figure 25. Power supply 5 can be one to be loaded with the printed circuit board (PCB) of 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 for 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 connected mode and the lamp plate of female plug, male plug again.

In other embodiments, electric connection between power supply 5 and the lamp plate 2 of any pattern also can replace above-mentioned male plug 51 and female plug 201 by conventional wires routing mode, adopt a traditional plain conductor, one end of plain conductor is electrically connected with power supply, the other end is electrically connected with lamp plate 2. Further, plain conductor can be coated an insulating 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 poor qualitatively.

In other embodiment, the electric connection between power supply 5 and lamp plate 2 can directly link together by rivet nail joint, tin cream gluing, welding or the mode with wire binding. Consistent with the fixed form of aforementioned lamp plate 2, a side surface of bendable circuit soft board is adhesively fixed in the inner peripheral surface of glass lamp 1 by bonding agent sheet 4, and the two ends of bendable circuit soft board can be selected 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, pay the utmost attention to female plug 201 is set on bendable circuit soft board, then the male plug of power supply 5 51 is inserted to female plug 201 and realize electrical connection.

If lamp plate 2 is not fixed on the inner peripheral surface of glass lamp 1 along the axial two ends of glass lamp 1, if adopt wire to connect, move in process follow-up, because two ends are free, easily shake in moving process follow-up, thereby likely make wire rupture. Therefore lamp plate 2 is preferentially chosen as welding with the connected mode of power supply 5. Particularly, with reference to Fig. 9, after can directly lamp plate 2 being got over, be welded on the output of power supply 5, remove the use of wire from, the stability of improving the quality of products. Now lamp plate 2 does not need to arrange female plug 201, and the output of power supply 5 does not need to arrange male plug 51 yet.

As shown in figure 11, the concrete practice can be that the output of power supply 5 is reserved to power pad a, and on power pad a, stay tin, with make the tin on pad thickness increase, convenient welding, accordingly, on the end of lamp plate 2, also reserve light source pad b, and the light source pad b of the power pad a of power supply 5 outputs and lamp plate 2 is welded together. The plane at pad place is defined as to front, lamp plate 2 docks the most firm with the connected mode of power supply 5 with the pad in both fronts, but at the back side that when welding is welded pressure head and must be pressed in lamp plate 2, come to scolding tin heating, than the problem that is easier to occur reliability across lamp plate 2. If as shown in figure 17, in the middle of light source pad b that will lamp plate 2 fronts, output hole, then the superposition that faced up welds on the power pad a in power supply 5 fronts, weld that pressure head can directly heating melts to scolding tin, to comparatively easily realizing on Practical Operation.

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, only not to be 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 free portion 21, and lamp plate 2 is fixed on the inner peripheral surface of glass lamp 1. Free portion 21 has above-mentioned pad b. In the time of assembling, one end that free portion 21 and power supply 5 weld can drive free portion 21 to glass lamp 1 internal contraction. As the bendable circuit soft board of lamp plate 2 can also not possess free portion and see through double-decker that a single layer pattern metallic circuit layer structure or a single layer pattern metallic circuit layer add one dielectric layer directly and power supply 5 be electrically connected. In the present embodiment, in the time that lamp plate 2 and power supply 5 connect, light source 202 surfaces, place on pad b and a and lamp plate, and are formed with through hole e as shown in figure 17 on pad b on lamp plate 2 in the same direction, and pad b and pad a are interconnected. When the free portion 21 of lamp plate 2 is towards the internal contraction of glass lamp 1 and while being out of shape, there is the pulling force of a side direction in the portion that is welded to connect between the printed circuit board (PCB) of power supply 5 and lamp plate 2 to power supply 5. Further, the pad b on pad a and the lamp plate 2 of power supply 5 is aspectant situation, and the portion that is welded to connect between printed circuit board (PCB) and the lamp plate 2 of the power supply 5 here also has a downward pulling force to power supply 5. This downward pulling force comes from the scolder in through hole e and between power supply 5 and lamp plate 2, forms more strengthening and a firmly electric connection.

As shown in figure 12, the light source pad b of lamp plate 2 is two unconnected pads, and with light source 202 both positive and negative polarity electrical connections, the size of pad is about 3.5 × 2mm respectively², on the printed circuit board (PCB) of power supply 5, also there is pad corresponding thereto, the top of pad is for ease of welding board automatic welding and have reserved tin, and the thickness of tin can be 0.1 to 0.7mm, and preferred values is 0.3 to 0.5mm comparatively appropriate, taking 0.4mm as best. One insulation hole c can be set between two pads, avoid two pads to cause electrical short circuit because scolding tin is welded together in the process of welding, the rear of this external insulated hole hole c also can arrange locating hole d, is used for allowing automatic welding board can correctly judge the tram of light source pad b.

The light source pad b of lamp plate has one at least, respectively with light source 202 both positive and negative polarity electrical connections. In other embodiments, in order to reach the extendibility in compatible and follow-up use, the quantity of light source pad b can have more than one, for example 2,3, more than 4 or 4. In the time that pad only has 1, corresponding two ends of lamp plate all can be electrically connected with power supply respectively, to form a loop, and the mode that now can utilize electronic building brick to replace, for example: replace electric capacity with inductance and be used as current stabilization assembly. As shown in Figure 13 to 27, in the time that pad is 3, the 3rd pad can use as ground connection, and in the time that pad is 4, the 4th pad can be used for signal input end. Accordingly, power pad a is also identical with light source pad b quantity. When pad is when more than 3, the arrangement between pad can be row side by side or line up two row, the accommodating size during according to actual use configure in position, needs only and is not electrically connected and causes short circuit each other. In other embodiments, if partly circuit production is 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, is preferably 1.2 to 1.8mm, and the best is 1.5mm, and the too little tin that welds use is difficult for passing through. In the time that the power pad a of power supply 5 and the light source pad b of lamp plate 2 weld together, the tin of welding use can be through described welding perforation e, then be deposited in cooling the condensing in welding perforation e top, formation has the ball structure g that is greater than welding perforation e diameter, it similarly is the function of nail that this ball structure g can play, except the tin through between power pad a and light source pad b is fixing, more can strengthen because of the effect of ball structure g the firm fixed of electric connection.

As shown in Figure 18 to Figure 19, in other embodiments, when the welding perforation e of light source pad b is during apart from the Bian Yuan≤1mm of lamp plate 2, the tin of welding use can be deposited in hole top edges through described hole e, too much tin also can reflux toward below from the edge of lamp plate 2, then, together with condensing in the tin on power pad a, its structure similarly is that a rivet is followed closely lamp plate 2 on the circuit board of power supply 5 firmly, has reliable electricity connection function. As shown in Figure 20 and Figure 21, in other embodiments, welding breach f has replaced welding perforation e, the welding perforation of pad is at edge, the tin of welding use sees through described welding breach f fixing to power pad a and light source pad b electrical connection, tin is more easily climbed up light source pad b and is deposited in around welding breach f, has when having more tin formation after cooling condensing the soldered ball that is greater 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 similarly is the function of C staple that the tin of welding use plays.

Please refer to Figure 22 and Figure 23, in other embodiment, above-mentioned fixing lamp plate 2 and the power supply 5 of welding manner that see through can replace with the circuit board group component 25 that is equipped with power supply module 250. Circuit board group component 25 has a long circuit plate 251 and a short circuit board 253, and long circuit plate 251 and short circuit board 253 are fitted each other and fixed through gluing mode, and short circuit board 253 is positioned near long circuit plate 251 peripheries.
