Refer to Fig. 2 and Figure 15, the glass lamp of the LED straight lamp proposed in this utility model one embodiment has knot Structure strengthening end, is described as follows.Glass fluorescent tube 1 includes body zone 102 and lays respectively at the end region at body zone 102 two ends 101, it is sheathed on the lamp holder outside end region 101 respectively.The external diameter of at least one end region 101 is less than the external diameter of body zone 102.This In embodiment, the external diameter arranging two end region 101 is respectively less than the external diameter of body zone 102, and the section of end region 101 is a plane And it is parallel with body zone 102.Specifically, intensive treatment is passed through at the two ends of fluorescent tube 1, and end region 101 forms strengthening section structure, lamp holder 3 are enclosed within the end region 101 after strengthening, and the difference of lamp holder 3 external diameter and lamp tube body district 102 external diameter diminishes, phase even completely Flat, i.e. lamp holder 3 external diameter is equal with body zone 102 external diameter and makes to have gap to produce between lamp holder 3 and body zone 102.This Sample arranges and is advantageous in that, in transportation, packaging support will not only contact lamp holder 3, and it can contact lamp holder 3 He simultaneously Fluorescent tube 1 so that whole LED straight lamp uniform force, without making lamp holder 3 become unique stress point, it is to avoid lamp holder 3 and fluorescent tube The position that end region 101 connects is concentrated due to stress and is ruptured, and improves the quality of product, and has effect attractive in appearance concurrently.
In one embodiment, lamp holder 3 external diameter is of substantially equal with body zone 102 external diameter, and tolerance is at positive and negative 0.2mm (millimeter) In, the most positive and negative 1mm.The purpose of substantially equal with body zone 102 external diameter in order to reach lamp holder 3 external diameter, according to difference The thickness of lamp holder 3, the end region 101 after strengthening can be 1mm to 10mm with the difference range of body zone 102 external diameter；Or Preferably, the end region 101 after strengthening can be relaxed to 2mm to 7mm with the difference range of body zone 102 external diameter.
With reference to Figure 15, seamlessly transit between end region 101 and the body zone 102 of fluorescent tube 1, form a transition region 103.One In embodiment, the two ends of transition region 103 are all in cambered surface, i.e. the two ends of transition region 103 section vertically is arc shaped.Further Ground, the cambered surface one at the two ends of transition region 103 connects body zone 102, and another connects end region 101.The arc angle of cambered surface is more than nine Ten degree, and the outer surface of end region 101 is a continuous surface and still remains parallel from profile view with the outer surface of body zone 102. In other embodiments, the profile of transition region 103 can not be bending or curved.The a length of 1mm to 4mm of transition region 103, If less than 1mm, then the insufficient strength of transition region；If greater than 4mm, then can reduce the length of body zone 102, reduce luminescence Face, simultaneously need to the length of lamp holder 3 increases to coordinate with body zone 102 accordingly, causes the material of lamp holder 3 to increase.Real at other Execute in example, then transition region 103 can not also be arc.
With reference to Fig. 5 and Figure 16, in the present embodiment, fluorescent tube 1 is employing glass lamp, between body zone 102 and end region Transition region 103 between 101, can slightly in by continuous two there is radius of curvature R 1, inverted S-shaped curved surface that the cambered surface of R2 is constituted, The cambered surface close to body zone 102 of transition region 103 is outside convex, and transition region 103 close to end region 101 cambered surface in Indent.It is said that in general, ratio R1:R2 that relation is R1 < R2, R1 and R2 between the radius of curvature R 1 and R2 of two cambered surfaces is 1: 1.5 to 1:10, preferably in the range of 1:2.5 to 1:5, most preferably in the range of 1:3 to 1:4, the present embodiment uses R1:R2 to be about 1: 3, consequently, it is possible near the transition region 103 of end region 101, after intensive treatment so that glass is in internal layer tension, outer layer The state of pressurized；And near the transition region 103 of body zone 102, after intensive treatment so that glass is in internal layer pressurized, outward The state of layer tension；Thus reach to increase the purpose of transition region 103 intensity of glass lamp 1.
As a example by the standard fluorescent tube of T8, the external diametrical extent of the end region 101 after strengthening is 20.9mm to 23mm, if less than 20.9mm, then the internal diameter of end region 101 is too small, causes power supply unit cannot insert in fluorescent tube 1.The external diametrical extent of body zone 102 For 25mm to 28mm, if less than 25mm, then with existing process conditions, it has not been convenient to its two ends are made strengthening section and processes, if More than 28mm, industry standard will not met.

With reference to Figure 17, 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 light source 202 produces passes fluorescent tube 1 by after diffusion barrier 13.Light source 202 is sent by diffusion barrier 13 Light play the effect of diffusion, therefore, as long as light can be made to pass fluorescent tube 1, the cloth of diffusion barrier 13 after passing through diffusion barrier 13 again Put and 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 is coated on light source Diffusion coating (not shown) on 202 surfaces, or (or covering) diffusion outside light source 202 is covered as an outer housing Diaphragm.
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 not Contact.The general term of diffusion barrier sheet is optical diffusion sheet or optical diffusing plate, generally by PS polystyrene, the poly-methyl-prop of PMMA The combination of one or more in e pioic acid methyl ester, PET (polyethylene terephthalate), PC (Merlon) is arranged in pairs or groups diffusion grain Son, a kind of composite formed, when light is through this composite, diffusion phenomenon can occur, light Cheng Jun can be revised Even area source finally makes 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 Any 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 of collocation The diffusion coating formed, will have excellent diffusion and the effect of printing opacity (having an opportunity to reach more than 90%).Additionally it was also found that Lamp holder in conjunction with strengthening section glass sometimes can be defective in quality, has a little ratio easily to come off, as long as and this diffusion being coated with Layer is also coated onto on the outer surface of end region 101 of fluorescent tube, can increase rubbing between lamp holder and fluorescent tube between diffusion coating and PUR 6 Wiping power so that the frictional force between diffusion coating and PUR 6 is more than the end face of the end region 101 being not coated with fluorescent tube during diffusion coating And the frictional force between PUR, therefore lamp holder 3 is through the frictional force between diffusion coating and PUR 6, and the problem that lamp holder 3 comes off is just Can significantly solve.
In the present embodiment, allotment time, the constituent of diffusion coating include calcium carbonate, strontium phosphate (such as CMS-5000, White powder), thickening agent, and ceramics activated carbon (such as ceramic active carbon SW-C, colourless liquid).Specifically, 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 to 30 μm.Use the diffusion barrier 13 that this material is formed, can have about The light transmittance of 90%, it is however generally that, the scope of light transmittance is about 85% to 96%.It addition, this diffusion barrier 13 is except having Outside the effect of diffusion light, moreover it is possible to play the effect of electric isolution, so that when glass lamp ruptures, reduce what user got an electric shock Risk；Meanwhile, this diffusion barrier 13, so that light source 202 is when luminescence, allows light produce diffusion, toward penetrating from all directions, from And the rear of light source 202 can be shone, i.e. near the side of bendable circuit soft board, it is to avoid form dark space in the lamp vessel 1, promote The illumination comfort in space.Additionally, when selecting the diffusion coating of different materials composition, have alternatively possible embodiment, Can use diffusion barrier thickness range be 200 μm to 300 μm, and light transmittance controls between 92% to 94%, also has another Kind effect.
In other embodiments, diffusion coating can also calcium carbonate be main material, and a small amount of reflecting material of arranging in pairs or groups is (such as strontium phosphate Or barium sulfate), thickening agent, ceramic active carbon and deionized water, be coated on after mixing on the inner peripheral surface of glass lamp, coating Average thickness falls between 20 to 30 μm.Owing to the purpose of diffusion barrier is to allow light produce diffusion, diffusion phenomenon, for microcosmic, is Light is through the reflection of granule, and the grain diameter size of the reflecting material such as strontium phosphate or barium sulfate can be much larger than the grain of calcium carbonate Footpath, therefore, selects to add a small amount of reflecting material in diffusion coating, 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, carbonic acid The particle diameter of the granule of calcium about falls between 2 to 4 μm, and the particle diameter of the granule of calcium halophosphate activated by antimony andmanganese and aluminium oxide about respectively falls in 4 Between 6 μm and between 1 to 2 μm, as a example by calcium carbonate, when the claimed range of light transmittance falls 85% to 92%, overall with Calcium carbonate be the average thickness that need to coat of the diffusion coating of main material about in 20 to 30 μm, in identical light transmittance requirement scope Under (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 at 25 to 35 μm, oxygen Changing aluminum is that the average thickness that the diffusion coating of main material need to coat can fall in 10 to 15 μm.If light transmittance demand is higher, example 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 then needs thinner.
It is to say, according to the use occasion of fluorescent tube 1, and select different light transmittance demands, i.e. optional expansion to be coated Dissipate the main material of coating, corresponding formation thickness etc..Need to remark additionally, the light transmittance of diffusion barrier is the highest, user See 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 being additionally provided with reflectance coating 12, reflectance coating 12 is located to be had Around the lamp plate 2 of light source 202, and circumferentially take the part inner peripheral surface of fluorescent tube 1.As shown in figure 17, reflectance coating 12 is lamp plate 2 liang Side is circumferentially extending along fluorescent tube, and lamp plate 2 is generally within reflectance coating 12 centre position circumferentially.The setting of reflectance coating 12 has two sides The effect in face, on the one hand, when seeing fluorescent tube 1 from side (X-direction in figure), owing to there being reflectance coating 12 to stop, will not be immediately seen Light source 202, 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 more towards be not coated with reflectance coating direction irradiate so that LED straight lamp obtains identical radiation response with lower power, improves energy saving.
Specifically, reflectance coating 12 is attached on the inner peripheral surface of fluorescent tube 1, and offers corresponding with lamp plate 2 on reflectance coating 12 Perforate 12a, the size of perforate 12a should be consistent with lamp plate 2 or slightly larger than lamp plate 2, for accommodating the lamp plate with light source 202 2.During assembling, first the lamp plate 2 (or bendable circuit soft board) with light source 202 is arranged on the inner peripheral surface of fluorescent tube 1, then will be anti- Penetrate film 12 and be sticked at fluorescent tube inner peripheral surface, wherein the perforate 12a of reflectance coating 12 and lamp plate 2 one_to_one corresponding, so that lamp plate 2 is exposed to instead Penetrate outside film 12.
In one embodiment, the reflectance of reflectance coating 12 is at least greater than 85%, and reflecting effect is preferable, typically more than 90% Time, it is therefore desirable to reach more than 95%, to obtain more preferably reflecting effect.Reflectance coating 12 is along the circumferentially extending length of fluorescent tube 1 Occupy the 30% to 50% of whole fluorescent tube 1 circumference, say, that along the circumferential direction of fluorescent tube 1, the circumferential lengths of reflectance coating 12 with Proportion between the girth of fluorescent tube 1 inner peripheral surface is 0.3 to 0.5.Spy gives explanation, and this utility model only sets with lamp plate 2 Put as a example by reflectance coating 12 medium position circumferentially, say, that lamp plate 2 both sides reflectance coating 12 has the face being substantially the same Long-pending, as shown in figure 17.The material of reflectance coating can be PET, strontium phosphate and barium sulfate any of which, or the most wantonly two kinds Combination, or the combination of three kinds, reflecting effect is more preferable, and thickness is between 140 μm to 350 μm, typically in 150 μm to 220 μm Between, better.As shown in figure 18, in other embodiments, reflectance coating 12 can only be located at the side of lamp plate 2, i.e. reflects Film 12 and the circumferential side contacts of lamp plate 2, the ratio that its circumference one side occupies fluorescent tube 1 circumference is similarly 0.3 to 0.5.Or, such as figure 19, shown in 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, The most again the lamp plate 2 with light source 202 is fixed on reflectance coating 12, herein reflectance coating 12 can also in the side of lamp plate 2 or Both sides are circumferentially extending along fluorescent tube respectively.
All kinds reflectance coating 12 described in the above-described embodiments can arbitrarily be arranged in pairs or groups with all kinds diffusion barrier 13, and Can realization individually reflect, independent diffusion or realization reflection simultaneously and the optical effect spread.For example, it is possible to only arrange reflectance coating 12, it is 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 ink material The circuit protecting layer of material, and ink material has the effect of reflection light, therefore at the position widened, circuit board itself is the most permissible Play such as the effect of reflectance coating 12 function.Preferably, bendable circuit soft board is along the circumferentially extending length of fluorescent tube 2 and described fluorescent tube Proportion between the girth of 2 inner peripheral surfaces is 0.3 to 0.5.A circuit protecting layer, circuit can be coated with outside bendable circuit soft board Protective layer can be a kind of ink material, has the function increasing reflection, and the bendable circuit soft board widened is with light source as starting point To circumferentially extending, the light of light source can make light more concentrate by the position widened.
In other examples, on the inner peripheral surface of glass tubing, can all coat diffusion coating, or part is coated Diffusion coating (is not coated with in place of having reflectance coating 12), but the most any mode, the end of diffusion coating fluorescent tube to be coated onto 1 On the outer surface of petiolarea, so that the gluing between lamp holder 3 and fluorescent tube 1 is more firm.
Need to supplement, in this utility model above-described embodiment, all can be selected for by diffusion coating, diffusion barrier sheet, reflection One in the group that film and adhesive film are formed, is applied to the optical treatment of this utility model light source emitted light.
Continuing referring to Fig. 2, in this utility model one embodiment, LED straight lamp also includes that bonding agent sheet 4, lamp plate insulate 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 Thinking silica gel, its form does not limits, and can be several sections shown in figure, or a section in strip.Various forms of bonding agents Sheet 4, various forms of lamp plate insulation film 7 and various forms of light source film 8 can combine each other and constitute this utility model it Different embodiments.
