With reference to Figure 17, except being close to lamp plate 2 (or the bendable electricity of fluorescent tube 1 in the fluorescent tube 1 of the present embodiment Road soft board) outward, also include diffusion barrier 13, the light that light source 202 produces passes fluorescent tube by after diffusion barrier 13 1.The light that light source 202 sends is played the effect of diffusion by diffusion barrier 13, therefore, as long as light can be made saturating Passing fluorescent tube 1 after crossing 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 fluorescent tube 1, or the diffusion being coated on light source 202 surface is coated with Layer (not shown), or (or covering) diffusion barrier sheet outside light source 202 is covered as an outer housing.

Referring once again to Figure 17, when diffusion barrier 13 is diffusion barrier sheet, it can cover on outside light source 202, and with Light source 202 does not contacts.The general term of diffusion barrier sheet is optical diffusion sheet or optical diffusing plate, generally uses PS Polystyrene, PMMA polymethyl methacrylate, PET (polyethylene terephthalate), PC (gather Carbonic ester) in the combination of one or more arrange in pairs or groups diffusion particle, a kind of composite formed, when When light is through this composite, diffusion phenomenon can occur, light uniformly area source can be revised to reach light The effect learning diffusion finally makes to be distributed from the brightness uniformity of fluorescent tube.

When diffusion barrier 13 is diffusion coating, its main component can be calcium carbonate, calcium halophosphate activated by antimony andmanganese and oxidation Aluminum wherein any one, or the combination of the most wantonly two kinds, or the combination of three kinds.It is main when utilizing calcium carbonate The diffusion coating that the suitable solution of material adapted is formed, will have excellent diffusion and printing opacity (has an opportunity to reach To more than 90%) effect.Additionally it was also found that the lamp holder combining strengthening section glass sometimes has quality asks Topic, has a little ratio easily to come off, as long as and this diffusion coating being also coated onto the end region 101 of fluorescent tube On outer surface, the frictional force between lamp holder and fluorescent tube between diffusion coating and PUR 6, can be increased so that diffusion is coated with Frictional force between layer and PUR 6 is more than end face and the heat of the end region 101 being not coated with fluorescent tube during diffusion coating Frictional force between melten gel, therefore lamp holder 3 takes off through the frictional force between diffusion coating and PUR 6, lamp holder 3 The problem fallen just can significantly solve.

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, nothing Color liquid).Specifically, when diffusion coating is with calcium carbonate as main material, arrange in pairs or groups thickening agent, ceramic active carbon with And deionized water, be coated on after mixing on the inner peripheral surface of glass lamp, the average thickness of coating fall 20 to Between 30 μm.Use the diffusion barrier 13 that this material is formed, can have the light transmittance of about 90%, typically For, the scope of light transmittance is about 85% to 96%.It addition, this diffusion barrier 13 is except having diffusion light Effect outside, moreover it is possible to play the effect of electric isolution, so that when glass lamp ruptures, reduce user The risk got an electric shock；Meanwhile, this diffusion barrier 13, so that light source 202 is when luminescence, allows light produce diffusion, Toward penetrating from all directions such that it is able to shine the rear of light source 202, i.e. near the one of bendable circuit soft board Side, it is to avoid form dark space in the lamp vessel 1, the illumination comfort of room for promotion.Additionally, when selecting different material During the diffusion coating of material composition, there is alternatively possible embodiment, can use the diffusion barrier thickness range to be 200 μm are 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 of arranging in pairs or groups a small amount of (as Strontium phosphate or barium sulfate), thickening agent, ceramic active carbon and deionized water, be coated on glass lamp after mixing Inner peripheral surface on, the average thickness of coating falls between 20 to 30 μm.Owing to the purpose of diffusion barrier is to allow Light produces diffusion, and diffusion phenomenon, for microcosmic, is the light reflection through granule, strontium phosphate or sulphuric acid The grain diameter size of the reflecting materials such as barium can be much larger than the particle diameter of calcium carbonate, therefore, selects in diffusion coating Add a small amount of reflecting material, can effectively increase the diffusion effect of light.

Certainly, in other embodiments, it is also possible to selection calcium halophosphate activated by antimony andmanganese or the main material that aluminium oxide is diffusion coating Material, the particle diameter of the granule of calcium carbonate about falls between 2 to 4 μm, and calcium halophosphate activated by antimony andmanganese and the granule of aluminium oxide Particle diameter about respectively fall between 4 to 6 μm and between 1 to 2 μm, as a example by calcium carbonate, work as printing opacity The claimed range of rate falls when 85% to 92%, and the overall diffusion coating with calcium carbonate as main material needs coating Average thickness about in 20 to 30 μm, under identical light transmittance requirement scope (85% to 92%), halogen phosphorus Acid calcium is that the average thickness that the diffusion coating of main material need to coat can fall in 25 to 35 μm, and aluminium oxide is main The average thickness wanting the diffusion coating of material to coat can fall in 10 to 15 μm.If light transmittance demand is higher, Such as more than 92%, then the diffusion coating thickness with calcium carbonate, calcium halophosphate activated by antimony andmanganese or aluminium oxide as main material is then Need thinner.

It is to say, according to the use occasion of fluorescent tube 1, and select different light transmittance demands, i.e. may select institute The main material of diffusion coating to be coated, corresponding formation thickness etc..Need to remark additionally, diffusion barrier Light transmittance the highest, user sees that the granular sensation of light source can be the most significant.

With continued reference to Figure 17, further, the inner peripheral surface of fluorescent tube 1 is additionally provided with reflectance coating 12, reflectance coating 12 It is located at and has around the lamp plate 2 of light source 202, and circumferentially take the part inner peripheral surface of fluorescent tube 1.Such as Figure 17 Shown in, reflectance coating 12 is circumferentially extending along fluorescent tube in lamp plate 2 both sides, and lamp plate 2 is generally within reflectance coating 12 edge The centre position of circumference.The setting of reflectance coating 12 has both sides effect, on the one hand, when from side (figure Middle X-direction) when seeing fluorescent tube 1, owing to there being reflectance coating 12 to stop, light source 202 will not be immediately seen, thus Reduce the visual discomfort that granular sensation causes；On the other hand, the light that light source 202 sends is through reflectance coating 12 Reflection, the angle of divergence of fluorescent tube can be controlled so that light is more towards the side being not coated with reflectance coating To irradiation so that LED straight lamp obtains identical radiation response with lower power, improve energy saving.

Specifically, reflectance coating 12 is attached on the inner peripheral surface of fluorescent tube 1, and offers and lamp on reflectance coating 12 The perforate 12a of plate 2 correspondence, the size of perforate 12a should be consistent with lamp plate 2 or slightly larger than lamp plate 2, uses In accommodating the lamp plate 2 with light source 202.During assembling, first by (or bendable for the lamp plate 2 with light source 202 Circuit soft board) it is arranged on the inner peripheral surface of fluorescent tube 1, then reflectance coating 12 is sticked at fluorescent tube inner peripheral surface, wherein The perforate 12a of reflectance coating 12 and lamp plate 2 one_to_one corresponding, outside being exposed to reflectance coating 12 by lamp plate 2.

In one embodiment, the reflectance of reflectance coating 12 is at least greater than 85%, and reflecting effect is preferable, typically exists When more than 90%, it is therefore desirable to reach more than 95%, to obtain more preferably reflecting effect.Reflectance coating 12 edge The circumferentially extending length of fluorescent tube 1 occupies the 30% to 50% of whole fluorescent tube 1 circumference, say, that along fluorescent tube 1 Circumferential direction, the proportion between circumferential lengths and the girth of fluorescent tube 1 inner peripheral surface of reflectance coating 12 is 0.3 To 0.5.Spy gives explanation, and this utility model is only arranged on reflectance coating 12 middle part circumferentially with lamp plate 2 As a example by position, say, that lamp plate 2 both sides reflectance coating 12 has the area being substantially the same, such as Figure 17 Shown in.The material of reflectance coating can be PET, strontium phosphate and barium sulfate any of which, or wherein appoints The combination of two kinds, or the combination of three kinds, reflecting effect is more preferable, thickness between 140 μm to 350 μm, General between 150 μm to 220 μm, better.As shown in figure 18, in other embodiments, instead Penetrate film 12 and can only be located at the circumferential side contacts in the side of lamp plate 2, i.e. reflectance coating 12 and lamp plate 2, its week The ratio occupying fluorescent tube 1 circumference to one side is similarly 0.3 to 0.5.Or, as shown in Figure 19, Figure 20, Reflectance coating 12 can not offer perforate, is directly sticked on the inner peripheral surface of fluorescent tube 1 by reflectance coating 12 during assembling, Being fixed on reflectance coating 12 by lamp plate 2 with light source 202, reflectance coating 12 can also be herein the most again The one or both sides of lamp plate 2 are circumferentially extending along fluorescent tube respectively.

All kinds reflectance coating 12 described in the above-described embodiments can be any with all kinds diffusion barrier 13 Collocation, and individually reflection can be realized, individually spread or realize reflection and the optical effect of diffusion simultaneously.Such as, Reflectance coating 12 can be only set, be not provided with diffusion barrier 13, as shown in Figure 19, Figure 20 and Figure 21.

In other embodiments, the width of bendable circuit soft board can be widened, 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 along lamp Proportion between length and the girth of described fluorescent tube 2 inner peripheral surface that pipe 2 is circumferentially extending is 0.3 to 0.5. Can be coated with a circuit protecting layer outside bendable circuit soft board, circuit protecting layer can be a kind of ink material, tool Have increase reflection function, the bendable circuit soft board widened with light source for starting point to circumferentially extending, light source Light 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 Part coats diffusion coating (not being coated with in place of having reflectance coating 12), but the most any mode, diffusion coating On the outer surface of the end region of fluorescent tube 1 to be coated onto, so that the gluing between lamp holder 3 and fluorescent tube 1 More firm.

Need to supplement, in this utility model above-described embodiment, all can be selected for by diffusion coating, diffusion barrier One in the group that sheet, reflectance coating and adhesive film are formed, is applied to this utility model light source and is sent The optical treatment of light.

Continue referring to Fig. 2, in this utility model one embodiment, LED straight lamp also include 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 fluorescent tube 1 by bonding agent sheet 4. Shown in figure, bonding agent sheet 4 can be silica gel, and its form does not limits, and can be several sections shown in figure, or Person is a section of strip.Various forms of bonding agent sheets 4, various forms of lamp plate insulation film 7 and various The light source film 8 of form can combine each other and constitute the difference embodiment of this utility model.

Lamp plate insulation film 7 is applied to lamp plate 2 towards on the surface of light source 202 so that lamp plate 2 does not exposes, Thus play the insulating effect being isolated from the outside by lamp plate 2.Lead to corresponding with light source 202 is reserved during gluing Hole 71, light source 202 is located in through hole 71.The constituent of lamp plate insulation film 7 includes the poly-silica of vinyl Alkane, hydrogen-based polysiloxanes and aluminium oxide.The thickness range of lamp plate insulation film 7 is that 100 μm are to 140 μm (micron).If less than 100 μm, then do not have enough insulating effects, if greater than 140 μm, then The waste of material can be caused.

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 thoroughly Light rate.Coating to light source 202 surface, 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..The scope that the refractive index of light source film 8 allows Be 1.22～1.6, if the refractive index of light source film 8 be light source 202 housing refractive index open radical sign, or light The refractive index of source film 8 be light source 202 housing refractive index open positive and negative the 15% of radical sign, then light transmittance is preferable. Here light source shell refers to accommodate the housing of LED grain (or chip).In the present embodiment, light source film The ranges of indices of refraction of 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 incessantly light source 202, poor effect, if greater than 1.3mm, then can reduce Light transmittance, the most also can increase material cost.

During assembling, first light source film 8 is applied to the surface of light source 202；Then insulate film 7 by lamp plate It is applied on the side surface on lamp plate 2；Again light source 202 is fixed on lamp plate 2；Then by lamp plate 2 with The opposing side surface of light source 202 pastes the inner peripheral surface being fixed on fluorescent tube 1 by bonding agent sheet 4；The most again Lamp holder 3 is fixed on the end region of fluorescent tube 1, light source 202 is electrically connected with power supply 5 simultaneously.Or such as Shown in Figure 22, utilize bendable circuit soft board 2 to get over transition region 103 and power supply 5 welds (i.e. through transition District 103 welds with power supply 5), or take the mode of conventional wires routing allow lamp plate 2 phase electrical with power supply 5 Even, last lamp holder 3 is by the way of Fig. 5 (by the structure of Fig. 3-Fig. 4) or Fig. 7 (by the structure of Fig. 6) It is connected on the transition region 103 of intensive treatment, forms a complete LED straight lamp.

In the present embodiment, lamp plate 2 is fixed on the inner peripheral surface of fluorescent tube 1 by bonding agent sheet 4 so that lamp plate 2 Being sticked on the inner peripheral surface of fluorescent tube 1, so can increase the lighting angle of whole LED straight lamp, expansion can Visual angle, so arranges general so that angle of visibility can be more than 330 degree.Exhausted by being coated with lamp plate at lamp plate 2 Edge film 7, is coated with the light source film 8 of insulation on light source 202, it is achieved the insulation processing to whole lamp plate 2, Such that make fluorescent tube 1 rupture, electric shock accidents also will not occur, improve safety.

Further, fluorescent tube 1 inner peripheral surface or outer peripheral face can be coated with adhesive film (not shown), at lamp Pipe 1 rupture after outwardly and inwardly isolating fluorescent tube 1.Adhesive film is coated in fluorescent tube 1 by the present embodiment On inner peripheral surface.

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 fluorescent tube 1 inner peripheral surface and solidifies, dimethylbenzene can volatilize Falling, its effect mainly regulates viscosity, and then regulates the thickness of adhesive film.

In one embodiment, the thickness range of adhesive film is that 100 μm are to 140 μm.If adhesive film thickness is little Inadequate in 100 μm then explosion-proof performance, during glass breaking, whole fluorescent tube can split, and then can more than 140 μm Reduce light transmittance, and increase material cost.If explosion-proof performance and light transmittance requirement are relatively loose, then adhesive film Thickness range can also be relaxed to 10 μm to 800 μm.

In the present embodiment, owing to scribbling adhesive film inside fluorescent tube, after glass lamp is broken, adhesive film can be by Fragment adhesion together, and will not form the through hole that through fluorescent tube is inside and outside, thus prevents user from contacting To the electrical body within fluorescent tube 1, to avoid electric shock accidents, use the adhesive film of said ratio also simultaneously There is diffusion light, the effect of printing opacity, improve Luminescence Uniformity and the light transmittance of whole LED straight lamp.This reality The adhesive film executing example can use with aforesaid bonding agent sheet 4, lamp plate insulation film 7 and light source film 8 collocation, And constitute various different embodiments of the present utility model.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, appointing during lamp plate 2 can be strip aluminium base, FR4 plate or bendable circuit soft board Meaning one.Owing to the fluorescent tube 1 of the present embodiment is glass lamp, if lamp plate 2 uses the strip aluminum base of rigidity Plate or FR4 plate, then when fluorescent tube ruptures, such as after breaking in two, whole fluorescent tube is still able to remain The state of straight tube, at this moment user likely will be considered that LED straight lamp can also use and go to install voluntarily, It is easily caused electric shock accidents.Owing to bendable circuit soft board has stronger pliability and flexible characteristic, Solve the situation that rigid strip aluminium base, FR4 plate pliability and bendability are not enough, the therefore lamp of the present embodiment Plate 2 uses bendable circuit soft board, so after fluorescent tube 1 ruptures, i.e. cannot support the fluorescent tube 1 ruptured and continue Continue and remain straight tube state, to inform that user LED straight lamp can not use, it is to avoid electric shock accidents Occur.Therefore, after using bendable circuit soft board, can alleviate to a certain extent owing to glass tubing breaks Broken and the electric shock problem that causes.Following example i.e. explain using bendable circuit soft board as lamp plate 2.

Refer to Figure 23, the bendable circuit soft board as lamp plate 2 includes one layer of circuit with conductive effect Layer 2a, light source 202 is located on line layer 2a, is connected with power sourced electric by line layer 2a.With reference to Figure 23, In the present embodiment, bendable circuit soft board can also include one dielectric layer 2b, overlapped with line layer 2a, is situated between Electric layer 2b and the area equation of line layer 2a, line layer 2a is used for arranging on the surface opposing with dielectric layer 2b Light source 202.Line layer 2a is electrically connected to power supply 5 in order to allow DC current pass through.Dielectric layer 2b with line Surface opposing for road floor 2a is then adhered on the inner peripheral surface of fluorescent tube 1 by bonding agent sheet 4.Wherein, line layer 2a can be metal level, or is furnished with the bus plane of wire (such as copper cash).

In other embodiments, the outer surface of line layer 2a and dielectric layer 2b can be coated with a circuit protecting layer, Described circuit protecting layer can be a kind of ink material, has welding resistance and increases the function of reflection.Or, can The formula circuit soft board of scratching can be a Rotating fields, is i.e. only made up of, then at line layer 2a a sandwich circuit layer 2a The circuit protecting layer of one layer of above-mentioned ink material of Surface coating.Whether a sandwich circuit layer 2a structure or two layers Structure (a sandwich circuit layer 2a and one dielectric layer 2b) can coupled circuit protective layer.Circuit protecting layer is also The most only electricity can be set in the side with light source 202 in the side surface configuration of bendable circuit soft board Road protective layer.It should be noted that bendable circuit soft board is a sandwich circuit Rotating fields 2a or is two-layer structure (a sandwich circuit layer 2a and one dielectric layer 2b), hence it is evident that than three layers of general flexible base board (in two sandwich circuit layers Folder one dielectric layer) more pliability and flexibility, therefore, can arrange in pairs or groups with having special formed fluorescent tube 1 (such as: non-straight lamp), and bendable circuit soft board is close on fluorescent tube 1 tube wall.Additionally, bendable electricity Road soft board is close to tube wall for preferably to configure, and the number of plies of bendable circuit soft board is the fewest, then dispel the heat Effect is the best, and material cost is the lowest, more environmentally friendly, and pliable and tough effect also has an opportunity to promote.

Certainly, bendable circuit soft board of the present utility model is not limited in one layer or double layer circuit plate, at it In his embodiment, bendable circuit soft board includes multilayer line layer 2a and multilayer dielectric layer 2b, dielectric layer 2b Can sequentially interlock overlapped with line layer 2a and be located at the line layer 2a side opposing with light source 202, light source 202 It is located at the last layer of multilayer line layer 2a, is connected with power sourced electric by the last layer of line layer 2a.? In other embodiments, as the length of bendable circuit soft board of lamp plate 2 more than the length of fluorescent tube.

Refer to Figure 48, in one embodiment, as lamp plate 2 bendable circuit soft board the most sequentially Including a first line layer 2a, a dielectric layer 2b and one second line layer 2c, the thickness of the second line layer 2c More than the thickness of first line layer 2a, the length of lamp plate 2 is more than the length of fluorescent tube 1, wherein at lamp plate 2 not It is provided with light source 202 and protrudes from the stub area of fluorescent tube 1, first line layer 2a and the second line layer 2c Respectively through two through hole 203 and 204 electrical communication, but through hole 203 and 204 the most do not connect with Avoid short circuit.

Thereby mode, owing to the second line layer 2c thickness is relatively big, can play support first line layer 2a and dielectric The effect of layer 2b, allows lamp plate 2 be not likely to produce skew or deformation when being attached on the inner tubal wall of fluorescent tube 1 simultaneously, To promote fine ratio of product.Additionally, first line layer 2a and the second line layer 2c is electrically connected logical so that first Circuit layout on line layer 2a can extend to the second line layer 2c, allows the circuit layout on lamp plate 2 more Polynary.Furthermore, circuit location wiring originally becomes double-deck from monolayer, the line layer monolayer face on lamp plate 2 Long-pending, that is the size on width, can reduce further, allow batch carry out the lamp plate quantity of die bond permissible Increase, promote productivity ratio.

Further, lamp plate 2 it is not provided with light source 202 and protrudes from first in the stub area of fluorescent tube 1 Line layer 2a and the second line layer 2c, also can directly be utilized to realize the circuit layout of power supply module, and allow Power supply module is directly arranged on bendable circuit soft board and is achieved.

Continuing referring to Fig. 2, lamp plate 2 is provided with some light sources 202, is provided with power supply 5, light source in lamp holder 3 By lamp plate 2 electrical communication between 202 and power supply 5.In each embodiment of this utility model, power supply 5 can be Single body (the most all power supply modules are all integrated in parts), and be located in the lamp holder 3 of fluorescent tube 1 one end； Or power supply 5 can also be divided into two parts, (the most all power supply modules are separately positioned on two to be referred to as double individuality In parts), and two parts are respectively arranged in the lamp holder 3 of lamp tube ends.Make strong if fluorescent tube 1 only has one end When change portion processes, power supply prioritizing selection is single body, and is located at the lamp corresponding to the end region after strengthening 101 In 3.

No matter being single body or double individuality, the generation type of power supply can have Mutiple Choice, such as, electricity Source can be the module after a kind of embedding molding, specifically, uses the silica gel (heat conductivity of a kind of high heat conduction >=0.7w/m k), by mould, power supply module is carried out embedding molding, obtain power supply, this mode obtains Power supply there is the advantage that high insulation, high heat radiation, profile are more regular, and can easily with other structural members Coordinate.Or, exposed power supply module directly can also be inserted lamp holder for not make casting glue molding by power supply Inside, or after the exposed power supply module conventional thermal draw is encased, then it is internal to insert lamp holder 3.Change speech It, in each embodiment of this utility model, power supply 5 can be to carry electricity with monolithic printed circuit board (PCB) as shown in figure 23 The form of source module occurs, also can be to occur with the form of single module as shown in figure 38.

Refer to Fig. 2 and combine Figure 38, in an embodiment, one end of power supply 5 has male plug 51, another 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 for connecting outside The hollow conductive pin 301 of power supply.The male plug 51 of power supply 5 is inserted in the female plug 201 of lamp plate 2, and metal is inserted Pin 52 is inserted in the hollow conductive pin 301 of lamp holder 3.Now male plug 51 and female plug 201 are equivalent to switching Head, for electrically connecting power supply 5 and lamp plate 2.After metal ferrule 52 inserts in hollow conductive pin 301, Hollow conductive pin 301 is impacted so that hollow conductive pin 301 occurs slight deformation through outside stamping tool, Thus fix the metal ferrule 52 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 arrive lamp plate 2, and pass through lamp plate 2 arrive light source 202.But, the structure of power supply 5 is then not limited to modular pattern shown in Figure 38.Power supply 5 Can be a printed circuit board (PCB) being loaded with power supply module, then with male plug 51, the connected mode of female plug 201 and lamp Plate 2 is electrically connected with.

In other embodiments, the electric connection between power supply 5 and the lamp plate 2 of any pattern can also be with passing System wire routing mode replaces above-mentioned male plug 51 and female plug 201, i.e. uses a traditional plain conductor, Being electrically connected with power supply one end of plain conductor, the other end electrically connects with lamp plate 2.Further, plain conductor An insulated sleeve can be coated with avoid getting an electric shock with protection user.But the mode that wire routing connects is likely in fortune The problem having fracture during defeated, slightly worse in quality.

In other embodiments, the electric connection between power supply 5 and lamp plate 2 can pass through rivet nail joint, tin cream sticks Connect, weld or be directly linked together in the way of wire binding.Fixed form with aforementioned lamp plate 2 Unanimously, a side surface of bendable circuit soft board is bonded and fixed to the inner peripheral surface of fluorescent tube 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 fluorescent tube 1.

If the two ends of bendable circuit soft board are fixed on the inner peripheral surface of fluorescent tube 1, then pay the utmost attention to flexible Female plug 201 is set on formula circuit soft board, then the male plug 51 of power supply 5 is inserted female plug 201 and realize electrically connecting Connect.

If lamp plate 2 is not fixed on the inner peripheral surface of fluorescent tube 1 along the two ends that fluorescent tube 1 is axial, lead if used Line connects, and during follow-up moving, due to two ends freely, is susceptible to shake during follow-up moving Dynamic, thus make it possible to wire and rupture.Therefore lamp plate 2 and the connected mode prioritizing selection of power supply 5 For welding.Specifically, with reference to Figure 22, directly lamp plate 2 can be got over the transition region 103 of strengthening section structure After be welded on the outfan of power supply 5, 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.
