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 fluorescent tube 1 of the present embodiment in addition to the lamp plate 2 (or bendable circuit soft board) being close to fluorescent tube 1, Also including diffusion barrier 13, the light that LED light source 202 produces passes fluorescent tube 1 by after diffusion barrier 13.Diffusion barrier 13 is to LED The light that light source 202 sends plays the effect of diffusion, therefore, as long as light can be made to pass fluorescent tube 1 again after passing through diffusion barrier 13, 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 it is coated on the diffusion coating (not shown) on LED light source 202 surface, or cover as an outer housing (or hide Lid) diffusion barrier sheet outside LED light source 202.

Referring once again to Fig. 4, when diffusion barrier 13 is diffusion barrier sheet, it can cover on outside LED light source 202, and and LED light source 202 do not contact.The general term of diffusion barrier sheet is optical diffusion sheet or optical diffusing plate, generally with PS (polystyrene), PMMA The group of one or more in (polymethyl methacrylate), PET (polyethylene terephthalate), PC (Merlon) Incompatible collocation diffusion particle, a kind of composite formed.When light is through this composite, diffusion phenomenon can occur, Light uniformly area source can be revised finally make to be distributed from the brightness uniformity of fluorescent tube 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 appoint One, or the combination of the most wantonly two kinds, or the combination of three kinds.When utilizing calcium carbonate for the main material suitable solution institute shape of collocation The diffusion coating become, will have excellent diffusion and the effect of printing opacity (having an opportunity to reach more than 90%).

It is also preferred that the left diffusion barrier can be made up of calcium carbonate, strontium phosphate.Wherein, the expansion being made up of calcium carbonate, strontium phosphate Dissipate the preferable beneficial effect that film will make LED straight lamp can have transmittance and diffusibility concurrently.Meanwhile, current diffusion barrier is Keep preferable transmittance and diffusibility, its thickness generally in 200 μm to 300 μm, not only thickness is big but also cost is the highest；And The diffusion barrier of the application can obtain preferable transmittance and diffusibility under the thickness of 20 μm to 30 μm, and thickness is little, system Make technique simple and cost-effective.

In the present embodiment, allotment time, the constituent of diffusion coating include calcium carbonate, strontium phosphate (such as CMS-5000, in vain Color powder), thickening agent, and ceramics activated carbon (such as ceramic active carbon SW-C, colourless liquid).Specifically, it is coated with when diffusion Layer with calcium carbonate as main material, arrange in pairs or groups thickening agent, ceramic active carbon and deionized water, be coated on the interior of glass lamp after mixing On side face, the average thickness of coating falls between 20 μm to 30 μm.Use the diffusion barrier 13 that this material is formed, can have There is the light transmittance of about 90%, it is however generally that, the scope of light transmittance is about 85% to 96%.It addition, this diffusion barrier 13 except Have outside the effect of diffusion light, moreover it is possible to play the effect of electric isolution, so that when fluorescent tube ruptures, reduce what user got an electric shock Risk；Meanwhile, this diffusion barrier 13, so that LED light source 202 is when luminescence, allows light produce diffusion, toward from all directions Injection such that it is able to shine the rear of LED light source 202, i.e. near the side of bendable circuit soft board, it is to avoid in the lamp vessel 1 Form dark space, the illumination comfort of room for promotion.Additionally, when selecting the diffusion coating of different materials composition, have the another kind can Can embodiment, can use diffusion barrier thickness range be 200 μm to 300 μm, and light transmittance controls 92% to 94% Between, also have another kind of effect.

In other embodiments, diffusion coating can also calcium carbonate be main material, and the reflecting material arranging in pairs or groups a small amount of is (such as strontium phosphate or sulfur Acid barium), thickening agent, ceramic active carbon and deionized water, be coated on after mixing on the inner peripheral surface of fluorescent tube, coating average thick Degree falls between 20 μm to 30 μm.Owing to the purpose of diffusion barrier is to allow light produce diffusion, diffusion phenomenon, for microcosmic, is Light can be much larger than the particle diameter of calcium carbonate through the reflection of granule, the grain diameter size of the reflecting material such as strontium phosphate or barium sulfate, Therefore, select 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 selecting calcium halophosphate activated by antimony andmanganese or aluminium oxide is the main material of diffusion coating, calcium carbonate The particle diameter of granule about falls between 2 μm to 4 μm, and the particle diameter of the granule of calcium halophosphate activated by antimony andmanganese and aluminium oxide about respectively falls in 4 μm is between 6 μm and between 1 μm to 2 μm.As a example by calcium carbonate, when the claimed range of light transmittance falls 85% to 92% Time, the average thickness that the overall diffusion coating with calcium carbonate as main material need to coat is about in 20 μm to 30 μm, identical Under 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 coat can fall 25 μm to 35 μm, aluminium oxide is that the average thickness that the diffusion coating of main material need to coat can fall in 10 to 15 μm.If thoroughly When light rate demand is higher, such as more than 92%, then the diffusion coating with calcium carbonate, calcium halophosphate activated by antimony andmanganese or aluminium oxide as main material is thick Degree then needs thinner.

It is to say, according to the use occasion of fluorescent tube 1, and selecting different light transmittance demands, i.e. optional desire coats diffusion painting The main material of layer, corresponding formation thickness etc..Need to remark additionally, the light transmittance of diffusion barrier is the highest, and user is seen The granular sensation of LED light source can be the most significant.

In the present embodiment, scribbling adhesive film owing to fluorescent tube 1 is internal, after the fluorescent tube 1 of glass material is broken, adhesive film can be by broken Sheet adhesion together, and will not form the through hole that through fluorescent tube 1 is inside and outside, thus prevents user from touching in fluorescent tube 11 The electrical body in portion, to avoid electric shock accidents, uses the adhesive film of said ratio also to have diffusion light, the effect of printing opacity simultaneously, Improve Luminescence Uniformity and the light transmittance of whole LED straight lamp.The adhesive film of the present embodiment can with aforesaid bonding agent sheet 4, Lamp plate insulation film 7 and light source film 8 collocation use, and constitute the various different embodiments of the application.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 uses bendable circuit soft board, so after fluorescent tube 1 ruptures, i.e. cannot support The fluorescent tube 1 ruptured continues to remain straight tube state, to inform that user LED straight lamp can not use, it is to avoid electric shock accidents Generation.Therefore, after using bendable circuit soft board, can alleviate to a certain extent and cause owing to glass tubing crushes Electric shock problem.Described lamp plate 2 is a bendable circuit soft board and is a single layer patterning metallic circuit Rotating fields or a monolayer figure Case metallic circuit layer adds the double-decker of one dielectric layer.

Refer to Figure 10, in one embodiment, the bendable circuit soft board as lamp plate 2 includes one layer of list with conductive effect Pattern layers metallic circuit layer 2a, LED light source 202 is located on single layer patterning metallic circuit layer 2a, by single layer patterning Metallic circuit layer 2a connects with power sourced electric.The described line layer having conductive effect in this description can be described as again conductive layer. With reference to Figure 10, in the present embodiment, bendable circuit soft board can also include one dielectric layer 2b, with single layer patterning metal wire Floor 2a is overlapped on road, 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 LED light source 202 on the surface opposing with dielectric layer 2b.Single layer patterning metallic circuit layer 2a is electrically connected to Power supply module 5 passes through in order to allow DC current.Dielectric layer 2b is then leading to single layer patterning surface opposing for metallic circuit layer 2a Cross bonding agent sheet 4 to be adhered on the inner peripheral surface of fluorescent tube 1.

In other embodiments, the outer surface of single layer patterning metallic circuit layer 2a and dielectric layer 2b can be coated with a circuit protection Layer, 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 i.e. only made up of, then at single layer patterning metal one layer of single layer patterning metallic circuit layer 2a The surface of line 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 monolayer figure Case metallic circuit layer 2a structure or two-layer structure (one layer of single layer patterning metallic circuit layer 2a and one dielectric layer 2b) all may be used With coupled circuit protective layer.Circuit protecting layer the most only can also have LED in the side surface configuration of bendable circuit soft board The side of light source 202 arranges circuit protecting layer.It should be noted that bendable circuit soft board is one layer of single layer patterning metal wire Road Rotating fields 2a or be two-layer structure (floor single layer patterning metallic circuit floor 2a and one dielectric layer 2b), hence it is evident that than general Three layers of flexible base board (in two sandwich circuit layers press from both sides one dielectric layer) more pliability and flexibility, therefore, can with have special The fluorescent tube 1 of moulding is arranged in pairs or groups (such as: non-straight lamp), and is close to by bendable circuit soft board on fluorescent tube 1 tube wall.Additionally, Bendable circuit 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 radiating effect The best, and material cost is the lowest, and more environmentally friendly, pliable and tough effect also has an opportunity to promote.

In other embodiments, the length as the bendable circuit soft board of lamp plate 2 is more than the length of fluorescent tube.

Continuing referring to Fig. 2, lamp plate 2 is provided with some (at least one) LED light source 202, in lamp holder 3 (lamp adapter assembly) It is provided with power supply module 5, by lamp plate 2 electrical communication between LED light source 202 and power supply module 5.In each embodiment of the application, Power supply module 5 can be single body (the most all power supply modules are all integrated in parts), and is located at the lamp of fluorescent tube 1 one end In 3；Or power supply module 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.

No matter being single body or double individuality, the generation type of power supply module can have Mutiple Choice, and such as, power supply module can Think the module after a kind of embedding molding, specifically, use the silica gel (heat conductivity >=0.7w/m k) of a kind of high heat conduction, logical Crossing mould and power supply module is carried out embedding molding, obtain power supply, the power supply that this mode obtains has high insulation, height dispels the heat, outward The advantage that shape is more regular, and can coordinate with other structural members easily.Or, power supply module can also be for not making casting glue Type, directly inserts exposed power supply module inside lamp holder, or after the exposed power supply module conventional thermal draw is encased, then Insert lamp holder 3 internal.In other words, in each embodiment of the application, power supply module 5 can be as shown in Figure 9 with monolithic printed circuit Plate carries the form of power supply module to be occurred, also can be to occur with the form of single module as shown in figure 25.

Refer to Fig. 2 and combine Figure 25, in an embodiment, one end of power supply module 5 has male plug 51, and the other end has Metal ferrule 52, 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, As pin.The male plug 51 of power supply module 5 is inserted in the female plug 201 of lamp plate 2, and metal ferrule 52 is inserted in lamp holder 3 In hollow conductive pin 301.Now male plug 51 and female plug 201 are equivalent to adaptor, for by power supply module 5 and lamp plate 2 electricity Connect.After metal ferrule 52 inserts in hollow conductive pin 301, impact hollow conductive pin 301 through outside stamping tool, make Obtain hollow conductive pin 301 and slight deformation occurs, thus fix the metal ferrule 52 on power supply module 5, and realize electrically connecting Connect.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 arrive LED light source 202 by lamp plate 2.But, the structure of power supply module 5 is then not limited to modular pattern shown in Figure 25. Power supply module 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 are electrically connected with.Vice versa for it, can be that one end of power supply has female plug in another embodiment, and the end of lamp plate 2 is provided with Male plug, power supply is electrically connected with lamp plate by the connected mode of female plug, male plug again.

In other embodiments, the electric connection between power supply module 5 and the lamp plate 2 of any pattern can also be beaten by conventional wires Line mode replaces above-mentioned male plug 51 and female plug 201, i.e. uses a traditional plain conductor, by one end of plain conductor and electricity Source electrically connects, and the other end is electrically connected with lamp plate 2.Further, plain conductor can be coated with an insulated sleeve to protect user 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 module 5 and lamp plate 2 can pass through rivet nail joint, tin cream gluing, Weld or be directly linked together in the way of wire binding.Consistent with the fixed form of aforementioned lamp plate 2, bendable circuit One side surface of 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 are permissible Select fixing or be not 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 on bendable circuit soft board Female plug 201 is set, then the male plug 51 of power supply module 5 is inserted female plug 201 and realizes being electrically connected with.

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, if using wire to connect, rear Continuous move during, due to two ends freely, be susceptible to rock during follow-up moving, thus make it possible to wire and send out Raw fracture.Therefore lamp plate 2 with the connected mode prioritizing selection of power supply module 5 for welding.Specifically, with reference to Fig. 9, Ke Yizhi Connect on the outfan being welded in power supply module 5 after 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 module 5 is also without arranging male plug 51.

As shown in figure 11, the concrete practice can be that the outfan of power supply module 5 reserves power pad a, and at power pad a On 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 module 5 outfan with lamp plate 2 is welded together.By pad institute Plane definition be front, then lamp plate 2 docks the most firm with the connected mode of power supply module 5 with the pad in both fronts, But welding pressure head must be pressed in the back side of lamp plate 2 when welding, to heat scolding tin across lamp plate 2, being easier appearance can Problem by degree.If as shown in figure 17, in the middle of the light source pad b in lamp plate 2 front, output hole, then it is just faced Upper superposition welds on the power pad a in power supply module 5 front, then scolding tin heating can directly be melted by welding pressure head, right It is relatively easy on Practical Operation realize.

As shown in figure 11, in above-described embodiment, the bendable circuit soft board major part as lamp plate 2 is fixed in fluorescent tube 1 On side face, being only not to be fixed on the inner peripheral surface of fluorescent tube 1 at two ends, the lamp plate 2 not being fixed on fluorescent tube 1 inner peripheral surface is formed One freedom portion 21, and lamp plate 2 is fixed on the inner peripheral surface of fluorescent tube 1.Freedom portion 21 has above-mentioned pad b.When assembling, One end of freedom portion 21 and power supply module 5 welding can drive freedom portion 21 to fluorescent tube 1 internal contraction.Flexible as lamp plate 2 Formula circuit soft board can not also possess freedom portion and pass through a single layer patterning metallic circuit Rotating fields or a single layer patterning gold Genus line layer is added the double-decker of one dielectric layer and is directly electrically connected with power supply module 5.In the present embodiment, lamp is worked as When plate 2 and power supply module 5 connect, the surface, LED light source 202 place on pad b and a and lamp plate in the same direction, and lamp Through hole e as shown in figure 17 it is formed with so that pad b and pad a is interconnected on pad b on plate 2.When lamp plate 2 Freedom portion 21 when deforming towards the internal contraction of fluorescent tube 1, the weldering between printed circuit board (PCB) and the lamp plate 2 of power supply module 5 Connection section has a lateral pulling force to power supply module 5.Further, compared to pad a and the lamp plate 2 of power supply module 5 On the aspectant situation of pad b system, the welded connection pair between printed circuit board (PCB) and the lamp plate 2 of power supply module 5 here Power supply module 5 also has a downward pulling force.This downward pulling force come from the solder in through hole e and in power supply module 5 and Form one between lamp plate 2 more strengthen and be firmly electrically connected with.

As shown in figure 12, the light source pad b of lamp plate 2 is two unconnected pads, respectively with LED light source 202 both positive and negative polarity Electrical connection, the size of pad is about 3.5 × 2mm², the printed circuit board (PCB) of power supply module 5 also has pad corresponding thereto, Being arranged above of pad is easy to weld board automatic welding and have reserved stannum, and the thickness of stannum can be 0.1 to 0.7mm, and preferred values is 0.3 to 0.5mm is more appropriate, is optimal with 0.4mm.One insulation hole c can be set between two pads, it is to avoid two Pad causes electrical short, the rear of this external insulated hole hole c also can arrange because scolding tin is welded together during welding 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 2 at least one, electrically connects with LED 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, such as 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 with shape Become primary Ioops, now may utilize the substituted mode of electronic building brick, such as: replace electric capacity as current stabilization assembly with inductance.Say at this In bright book, the meaning of " inductance " contains " inducer ", and the meaning of " electric capacity " contains " capacitor ", and the meaning of " resistance " Contain " resistor ".As shown in Figure 13 to Figure 16, when pad is 3, the 3rd pad can serve as ground connection and use, When pad is 4, the 4th pad can be used to make signal input end.Accordingly, power pad a also with light source pad b Quantity is identical.When pad is more than 3, the arrangement between pad can be that string side by side or lines up two row, according to actually used Time accommodating size configure in position, cause short circuit as long as the most not electrically connecting.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 the fewest, in work More flow process is saved in skill；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, welding The diameter of perforation e can be 1 to 2mm, preferably 1.2 to 1.8mm, most preferably 1.5mm, and the least, the stannum welded is not Easily pass through.When the power pad a of the power supply module 5 and light source pad b of lamp plate 2 welds together, the stannum of welding is permissible Through described welding perforation e, be then deposited in cooling above welding perforation e and condense, formed have straight more than welding perforation e It seems the function of nail that the ball structure g in footpath, this ball structure g can play, except through power pad a and light source pad Outside stannum between b is fixing, 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, when the welding perforation e of light source pad b is apart from the edge of lamp plate 2 During 1mm, the stannum of welding can be deposited in hole top edges through described hole e, and too much stannum also can be from lamp plate 2 Edge toward lower section reflux, be then coagulated together with the stannum on power pad a, its structure similarly is that a rivet is by lamp plate 2 Follow closely firmly on the circuit board of power supply module 5, there is reliable electricity connection function.As shown in Figure 20 and Figure 21, at it In his embodiment, welding breach f instead of welding perforation e, and the welding perforation of pad is at edge, and the stannum of welding is through institute The welding breach f stated electrically connects power pad a and light source pad b fixing, and stannum is easier to climb up light source pad b and be deposited in Around welding breach f, after cooling condenses, have more stannum form the soldered ball having more than welding breach f diameter, this weldering Spherical structure can allow the crystallized ability of electric connection structure strengthen.In the present embodiment, because the design of welding breach, the stannum of welding Playing seems the function of C-shaped nail.
