Technical field

This utility model relates to field of lighting appliances, is specifically related to a kind of LED straight lamp and comprises light source, electronic building brick and lamp holder with its element。

Background technology

LED illumination technology is just fast-developing and instead of traditional electric filament lamp and fluorescent lamp。Compared to the fluorescent lamp being filled with noble gas and hydrargyrum, LED straight lamp is without filling hydrargyrum。Therefore, various by seem the tradition illumination domestic dominated of option such as fluorescent bulbs and fluorescent tube or working space illuminator in, LED straight lamp is it is hardly surprising that be increasingly becoming the illumination option that people highly expect。The advantage of LED straight lamp comprises the ruggedness of lifting and life-span and relatively low power consuming。Thus it is contemplated that after all factors, LED straight lamp would is that the illumination option of escapable cost。

Known LED straight lamp generally comprises fluorescent tube, be located at fluorescent tube in and with the circuit board of light source, and be located at the lamp holder of lamp tube ends, be provided with power supply in lamp holder, be electrically connected by circuit board between light source and power supply。But, existing LED straight lamp still has following a few class quality problems to need to solve:

First, circuit board is generally rigid plate, and after fluorescent tube breaks, especially when partial fracture, whole LED straight lamp remains in the state of straight tube, and user can think that fluorescent tube can also use by mistake, thus going to install voluntarily, it is easy to cause occurring to leak electricity and electric shock accidents。

Second, in existing LED straight lamp, it is generally adopted plain conductor between rigid circuit board and lamp holder and realizes electrical connection through the mode of routing, in the manufacture of LED straight lamp, transport and use procedure, plain conductor routing easily damages owing to moving even rupture, and causes LED straight lamp to use。

3rd, in existing LED straight lamp, time bonding between lamp holder with fluorescent tube, generally use PUR or silica gel, after it is directly socketed lamp holder, wayward viscose glue overflow situation, if not removing unnecessary viscose glue, then affect attractive in appearance, cause Problem of Shading；If removing unnecessary viscose glue, then need to employ substantial amounts of artificial in manufacture process wiping, cause production obstacle and poor efficiency。In addition, the heat radiation of the source element in lamp holder is bad to be easily caused in lamp holder and forms hot environment, and then the service life reducing PUR reduces the cementability between fluorescent tube and lamp holder simultaneously, causes that the reliability of LED straight lamp declines。

4th, the fluorescent tube of prior art is generally uniform cylinder, and lamp sleeve is located at outside fluorescent tube and bonding by viscose glue with between fluorescent tube, and therefore, the external diameter of lamp holder is greater than the external diameter of fluorescent tube。During packaging, owing to packaging support is typically also the box body in Cylindrical Homogeneous, thus can only contact with lamp holder so that lamp holder becomes unique stress point, causing in transportation, the connecting portion of lamp holder and fluorescent tube is easily broken。The straight lamp being disclosed in the U.S. patent application case that publication number is US2014226320A is an example。Furthermore, publication number is the disclosed straight lamp of the Chinese patent application case of CN102518972 is another example。For this part, the U.S. patent application case that publication number is US20100103673A discloses a kind of LED straight lamp, its fluorescent tube is glass lamp, and is filled in by lamp holder in glass lamp so that the two ends of glass lamp are born internal stress and suffered at two ends to be easier to break during additional strength。This will cause product defect and quality problem。

5th, in existing LED straight lamp, visual granular sensation often occurs。The multiple LED grain being positioned on the circuit board within fluorescent tube to arrange belong to point source, because the characteristic of its point source, without suitable optical treatment, the uneven illumination in whole fluorescent tube is even。Therefore for the observer of LED straight lamp, whole fluorescent tube presents the effect with granular sensation or non-uniform illumination, affects the comfort level of vision, even the angular field of view of the emergent ray that narrowed。Stated differently, the quality of ordinary consumer and aesthetic will be unable to be satisfied。For this problem, application number is the Chinese patent application case of CN201320748271.6, discloses and is positioned among glass tubing by an anemostat, to reducing visual granular sensation。But, the setting of anemostat makes to add an interface in the propagation path of light, and probability of total reflection occurs increasing light when propagating for this so that the delivery efficiency of light reduces。Additionally, the suction optical activity of anemostat, the delivery efficiency causing light is reduced。

Because the problems referred to above, this utility model set forth below and embodiment。

1, high temperature modification ion exchange

In the temperature province between the softening point and transition point of glass, containing Na₂O or K₂The glass of O invades in the fused salt of lithium, make the Na ion in glass or the Li ion in the fused salt little with they radiuses be exchanged, be subsequently cooled to room temperature, owing to the top layer containing Li ion is different from containing Na ion or K ion inner layer expansion coefficient, surface produces residual pressure and strengthens, simultaneously；Glass neutralizes containing Al₂O₃、TiO₂Deng composition time, exchanged by ion, the crystallization that the coefficient of expansion is extremely low can be produced, the glass surface after cooling will produce very big pressure, can obtain the glass of intensity up to 700MPa。

2, low form ion exchange

Low-temperature ion exchange process, in the humidity province lower than strain point of glass, does ion exchange with the monovalent cation (such as K ion) than top layer basic ion (such as Na ion) also larger ionic radius with Na ion, makes the method that K ion enters top layer。Such as Na₂O+CaO+SiO₂System glass, can impregnate tens hours in the fuse salt of degree more than 400。Low form ion exchange can be readily attained high intensity, has processing method and simply, does not damage the features such as glass surface is transparent, indeformable。

3, dealkalize method

Dealkalize method is in the high-temperature atmosphere containing sulphurous acid gas and moisture, utilizes Pt catalyst treatment glass, makes Na+ ion ooze out from surface layer of glass and react with sulfurous acid, thus surface layer becomes rich SiO₂Layer, its result becomes low expansion glass due to top layer, produces compressive stress during cooling。

4, surface crystallization method

The exchange of surface crystallization method and high temperature modification ion is different, but only forms low-expansion microcrystal on top layer by heat treatment, thus so as to the method strengthened。

5, sodium silicate reinforcement

Sodium silicate reinforcement is will to process under the several of the above atmospheric pressure of 100° centigrade in the aqueous solution of sodium silicate (waterglass), thus obtaining the high strength glass being difficult to scratch top layer。

Use physics mode that glass does the mode strengthened, it is possible to include but not limited to, use the mode of coating or change the structure of article。The substrate that coating sprays as required determines kind and the state of coating, it is possible to be ceramic tile strengthened coat, acryl coating or glass coating etc., can be liquid or gaseous state coating when coating。Change the structure of article, for instance do structural strengthening design in easily rupturable part。

Below whether chemical mode or physics mode are not limited to single mode and implement, it is possible to any one in mixing physics mode or in chemical mode does any matched combined。

Refer to Fig. 2 and Figure 15, the glass lamp of LED straight lamp proposed in this utility model one embodiment has structure-reinforced end, illustrates as follows。Glass fluorescent tube 1 includes body zone 102 and lays respectively at the end region 101 at body zone 102 two ends, 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。In the present 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 parallel with body zone 102。Specifically, intensive treatment is passed through at the two ends of fluorescent tube 1, end region 101 forms strengthening section structure, lamp holder 3 is 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, even completely equal, namely lamp holder 3 external diameter is equal with body zone 102 external diameter and make to have gap to produce between lamp holder 3 and body zone 102。So arrange and be advantageous in that, in transportation, packaging support will not only contact lamp holder 3, it can contact lamp holder 3 and fluorescent tube 1 simultaneously, make whole LED straight lamp uniform force, without making lamp holder 3 become unique stress point, it is to avoid the position that lamp holder 3 is connected with fluorescent tube end region 101 is concentrated due to stress and broken, improve the quality of product, and have 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 in positive and negative 0.2mm (millimeter), no more than positive and negative 1mm。The purpose of substantially equal in order to reach lamp holder 3 external diameter and body zone 102 external diameter, the thickness according to different lamp holders 3, end region 101 and the difference range of body zone 102 external diameter after strengthening can be 1mm to 10mm；Or preferred, end region 101 and the difference range of body zone 102 external diameter after strengthening can be relaxed to 2mm to 7mm。

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。In one embodiment, the two ends of transition region 103 are all in cambered surface, and namely the two ends of transition region 103 section vertically is arc shaped。Further, 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 90 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 length of transition region 103 is 1mm to 4mm, if less than 1mm, then and the insufficient strength of transition region；If greater than 4mm, then can reduce the length of body zone 102, reduce light-emitting area, simultaneously need to the length of lamp holder 3 increases to coordinate with body zone 102 accordingly, cause the material of lamp holder 3 to increase。In other embodiments, 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, transition region 103 between body zone 102 and end region 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 the cambered surface close to end region 101 of transition region 103 is in concaving。Generally speaking, relation between radius of curvature R 1 and the R2 of two cambered surfaces is R1 < R2, the ratio R1:R2 of R1 and R2 is 1:1.5 to 1:10, it is advantageous to range for 1:2.5 to 1:5, best ranges for 1:3 to 1:4, the present embodiment adopts R1:R2 to be about 1:3, consequently, it is possible near the transition region 103 of end region 101, after intensive treatment, glass is made to be in internal layer tension, the state of outer layer pressurized；And near the transition region 103 of body zone 102, after intensive treatment so that glass is in internal layer pressurized, the state of outer layer tension；Thus reaching to increase the purpose of transition region 103 intensity of glass lamp 1。

For the standard fluorescent tube of T8, the external diametrical extent of the end region 101 after strengthening is 20.9mm to 23mm, and if less than 20.9mm, then the internal diameter of end region 101 is too small, causes that power supply unit cannot insert in fluorescent tube 1。The external diametrical extent of body zone 102 is 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 greater than 28mm, will not meet industry standard。

Refer to Fig. 3 and Fig. 4, in this utility model one embodiment, the lamp holder 3 of LED straight lamp includes an insulation tube 302, and one is fixedly arranged on the heat-conducting part 303 on insulation tube 302 outer peripheral face and two the hollow conductive pins 301 being located on insulation tube 302。Described heat-conducting part 303 can be the becket of a tubulose。

Refer to Fig. 5, in an embodiment, insulation tube 302 one end towards fluorescent tube is stretched out in one end of heat-conducting part 303, bonding by a PUR 6 between extension (stretching out the part of insulation tube) and the fluorescent tube 1 of heat-conducting part 303。Further, lamp holder 3 extends to transition region 103 by heat-conducting part 303, contact closely with transition region 103 by heat-conducting part 303 so that heat-conducting part 303 and fluorescent tube 1 by PUR 6 bonding time, do not have the subject ontology district 102 that PUR 6 overflows lamp holder 3 and remains to fluorescent tube 1。Additionally, insulation tube 302 does not extend to transition region 103 towards one end of fluorescent tube 1, namely insulation tube 302 keeps certain intervals between one end and transition region 103 of fluorescent tube。In the present embodiment, the material of insulation tube 302 does not limit the use material such as plastics, pottery, is not mainly the good conductor of electricity under general state。

Furthermore, PUR 6 is a kind of constituent, comprises a kind of material for welding powder, and composition is preferably: phenolic resin 2127#, Lac, Colophonium, calcite in powder, zinc oxide, ethanol etc.。In the present embodiment, Colophonium is a kind of tackifier, has and is dissolved in ethanol, but water-fast characteristic。This PUR 6 when high-temperature heating, can change its physical state and occur significantly to expand, reach the effect solidified, add the stickiness of material own, such that it is able to make lamp holder 3 and fluorescent tube 1 be in close contact, it is simple to LED straight lamp realizes automated production。In an embodiment, PUR 6 can present expansion after high-temperature heating and flow, and cools down the effect that namely can reach to solidify subsequently, and when PUR 6 is heated to the temperature of 200 to 250 degree Celsius from room temperature, the volume of PUR will expand to original 1 to 1.3 times。Certainly, the selection of this utility model PUR composition is not limited to this, also can be selected for the composition that high-temperature heating solidifies to predetermined temperature。Owing to this utility model PUR 6 will not form hot environment due to the heating of the heating element such as power supply module and cause reliability decrease, it is possible to prevent the adhesive property of fluorescent tube 1 and lamp holder 3 in LED straight lamp use procedure from reducing, raising long-term reliability。

Further, being formed with an accommodation space between the inner peripheral surface and the outer peripheral face of fluorescent tube 1 of heat-conducting part 303 extension, PUR 6 is filled in this accommodation space, position shown in dotted line B in Fig. 5。In other words, the position that PUR 6 is filled is passed through by the first virtual plane (plane crossed drawn by dotted line B in Fig. 5) axially vertical with fluorescent tube 1: direction radially inward, in the position of the first virtual plane, sequential is the outer peripheral face of heat-conducting part 303, PUR 6 and fluorescent tube 1。PUR 6 coating thickness can be 0.2mm to 0.5mm, and PUR 6 can solidify after expanding, thus contacting with fluorescent tube 1 and lamp holder 3 being fixed on fluorescent tube 1。And owing to having difference in height between the outer peripheral face of both end region 101 and body zone 102, PUR therefore can be avoided to spill in body zone 102 part of fluorescent tube, remove follow-up manual wipping process from, improve the yield of LED straight lamp。Add man-hour, conduct heat to heat-conducting part 303 by external heat equipment, then conduct again to PUR 6, make PUR 6 expand after cooling curing, thus lamp holder 3 is fixedly bonded on fluorescent tube 1。

Refer to Fig. 5, in an embodiment, insulation tube 302 includes the first pipe 302a and the second pipe 302b that connect vertically, and the external diameter of the second pipe 302b external diameter less than the first pipe 302a, the external diameter difference range of two pipes is 0.15mm to 0.3mm。Heat-conducting part 303 is located on the outer peripheral face of the second pipe 302b, and the outer surface of heat-conducting part 303 and the outer peripheral face of the first pipe 302a are concordant so that the outer surface flat smooth of lamp holder 3, it is ensured that whole LED straight lamp is uniform force in packaging, transportation。Wherein, heat-conducting part 303 along the axial length of length and the insulation tube 302 of lamp holder axial direction than for 1:2.5 to 1:5, i.e. heat-conducting part length: insulation tube length is 1:2.5 to 1:5。

In one embodiment, in order to ensure bonding fastness, the second pipe 302b is sheathed on outside fluorescent tube 1 at least partly, and accommodation space also includes the space between the inner surface of the second pipe 302b and end region 101 outer surface of fluorescent tube。PUR 6 has between the second pipe 302b and the fluorescent tube 1 being partially filled in mutually overlap (in Fig. 5 position shown in dotted line A), and namely part holt melt glue 6 is between the inner surface and the outer surface of end region 101 of the second pipe 302b。In other words, PUR 6 is filled in the position of described accommodation space to be passed through by the second virtual plane (plane crossed drawn by dotted line A in Fig. 5) that one and fluorescent tube are axially vertical: direction radially inward, in the position of the second virtual plane, sequential is heat-conducting part the 303, second pipe 302b, PUR 6 and end region 101。

In the present embodiment, PUR 6 is not required to be fully filled with above-mentioned accommodation space (accommodation space can also include the space between heat-conducting part 303 and the second pipe 302b in figure)。During manufacture, when coating hot-melt adhesive 6 between heat-conducting part 303 and end region 101, it is possible to suitably increase the amount of PUR so that in the process of subsequent heat, PUR can flow to due to expansion between the second pipe 302b and end region 101, bonds connection after cooling curing and then by both。

When making LED straight lamp, after the end region 101 of fluorescent tube 1 is inserted in lamp holder 3, the end region 101 of fluorescent tube 1 insert the axial length of lamp holder 3 part account for heat-conducting part 303 axial length 2/1 to three/3rds between, such benefit is: on the one hand, ensureing that hollow conductive pin 301 has enough creep age distances with heat-conducting part 303, both during energising, not easily short circuit makes people get an electric shock and initiation potential；On the other hand, due to the insulating effect of insulation tube 302 so that the creep age distance between hollow conductive pin 301 and heat-conducting part 303 strengthens, it is easier to make people get an electric shock and the test of initiation potential during by high voltage。

Further, for the PUR 6 of the second pipe 302b inner surface, the second pipe 302b is interposed between PUR 6 and heat-conducting part 303, and the effect that therefore heat conducts to PUR 6 from heat-conducting part 303 can be given a discount。For solving this problem, with reference to Fig. 4, the present embodiment arranges multiple breach 302c circumferentially arranged at the second pipe 302b towards one end (namely away from one end of the first pipe 302a) of fluorescent tube 1, increase the contact area of heat-conducting part 303 and PUR 6, it is beneficial to heat quickly conduct to PUR 6 from heat-conducting part 303, accelerates the solidification process of PUR 6。Meanwhile, when user touches heat-conducting part 303, due to the insulating effect of PUR 6 between heat-conducting part 303 and fluorescent tube 1, breakage will be had to get an electric shock because of fluorescent tube 1。

In other embodiments, lamp holder includes one for installing the power supply slot (not shown) of power supply module。

With reference to Figure 17, in the fluorescent tube 1 of the present embodiment except 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。The light that light source 202 sends is played the effect of diffusion by diffusion barrier 13, therefore, as long as fluorescent tube 1 is passed after making light therethrough diffusion barrier 13 again, the layout of diffusion barrier 13 can have various ways, such as: diffusion barrier 13 can be coated or covered with on the inner peripheral surface of fluorescent tube 1, or it is coated on the diffusion coating (not shown) on light source 202 surface, or covers (or covering) diffusion barrier sheet outside light source 202 as an outer housing。

Referring once again to Figure 17, when diffusion barrier 13 is diffusion barrier sheet, it can cover on outside light source 202, and does not contact with light source 202。The general term of diffusion barrier sheet is optical diffusion sheet or optical diffusing plate, arrange in pairs or groups diffusion particle typically by the combination of one or more in PS polystyrene, PMMA polymethyl methacrylate, PET (polyethylene terephthalate), PC (Merlon), a kind of composite formed, diffusion phenomenon can be there is when this composite of light therethrough, light uniformly area source can be revised and finally make to be distributed from the brightness uniformity of 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 wherein combination of wantonly two kinds, or the combination of three kinds。When the diffusion coating utilizing calcium carbonate to be formed for the main material suitable solution of collocation, will there is excellent diffusion and the effect of printing opacity (having an opportunity to reach more than 90%)。Additionally it have also been found that, lamp holder in conjunction with strengthening section glass sometimes can be defective in quality, a little ratio is had easily to come off, as long as and this diffusion coating is also coated onto on the outer surface of end region 101 of fluorescent tube, the frictional force between lamp holder and fluorescent tube can be increased between diffusion coating and PUR 6, make frictional force between diffusion coating and PUR 6 more than the end face of the end region 101 of fluorescent tube when being not coated with 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 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, colourless liquid)。Specifically, when diffusion coating is with calcium carbonate for main material, arrange in pairs or groups thickening agent, ceramic active carbon and deionized water, it is coated on after mixing on the inner peripheral surface of glass lamp, the average thickness of coating drops between 20 to 30 μm。Adopt the diffusion barrier 13 that this material is formed, it is possible to there is the light transmittance of about 90%, it is however generally that, light transmittance range from about 85% to 96%。It addition, this diffusion barrier 13 is except having the effect of diffusion light, moreover it is possible to play the effect of electric isolution, so that when glass lamp breaks, reduce the risk that user gets an electric shock；Meanwhile, this diffusion barrier 13 so that light source 202 is when luminescence, can allow light produce diffusion, toward penetrating from all directions such that it is able to shine the rear of light source 202, namely near the side of bendable circuit soft board, avoid being formed in the lamp vessel 1 dark space, the illumination comfort of room for promotion。Additionally, when selecting the diffusion coating of different materials composition, have alternatively possible embodiment, it is possible to adopting diffusion barrier thickness range is 200 μm to 300 μm, and light transmittance controls between 92% to 94%, also has another kind of effect。

In other embodiments, diffusion coating can also calcium carbonate be main material, the reflecting material (such as strontium phosphate or barium sulfate) of arranging in pairs or groups a small amount of, thickening agent, ceramic active carbon and deionized water, being coated on after mixing on the inner peripheral surface of glass lamp, the average thickness of coating drops between 20 to 30 μm。Owing to the purpose of diffusion barrier is to allow light produce diffusion, diffusion phenomenon is at microcosmic, it it is the light reflection through granule, the grain diameter size of the reflecting material such as strontium phosphate or barium sulfate can much larger than the particle diameter of calcium carbonate, therefore, select in diffusion coating, add a small amount of reflecting material, can effectively increase the diffusion effect of light。

Certainly, in other embodiments, can also select calcium halophosphate activated by antimony andmanganese or aluminium oxide is the main material of diffusion coating, the particle diameter of the granule of calcium carbonate about drops between 2 to 4 μm, and the particle diameter of the granule of calcium halophosphate activated by antimony andmanganese and aluminium oxide about respectively falls between 4 to 6 μm and between 1 to 2 μm, for calcium carbonate, when the claimed range of light transmittance drops on 85% to 92%, the average thickness that the diffusion coating that entirety is main material with calcium carbonate need to be coated with is about 20 to 30 μm, under identical light transmittance requirement scope (85% to 92%), calcium halophosphate activated by antimony andmanganese is that the average thickness that the diffusion coating of main material need to be coated with can drop on 25 to 35 μm, aluminium oxide is that the average thickness that the diffusion coating of main material need to be coated with can drop on 10 to 15 μm。If light transmittance demand is higher, for instance more than 92%, then the diffusion coating thickness being main material with calcium carbonate, calcium halophosphate activated by antimony andmanganese or aluminium oxide then needs thinner。

It is to say, according to the use occasion of fluorescent tube 1, and select different light transmittance demands, i.e. optional formation thickness being intended to the main material of coating diffusion coating, correspondence etc.。Need to remarking additionally, the light transmittance of diffusion barrier is more high, and user sees that the granular sensation of light source can be more significant。

With continued reference to 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 takies the part inner peripheral surface of fluorescent tube 1。As shown in figure 17, 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 centre position circumferentially。The setting of reflectance coating 12 has the effect of two aspects, on the one hand, when when from the side, (in figure X-direction) sees fluorescent tube 1, stops with reflectance coating 12, will not be immediately seen light source 202, thus reducing the visual discomfort that granular sensation causes；On the other hand, the light that light source 202 sends is through the reflection of reflectance coating 12, it is possible to control the angle of divergence of fluorescent tube so that light irradiates more towards the direction being not coated with reflectance coating, make LED straight lamp obtain identical radiation response with less power, improve energy saving。

Specifically, reflectance coating 12 is attached on the inner peripheral surface of fluorescent tube 1, and offers the perforate 12a corresponding with lamp plate 2 on reflectance coating 12, and the size of perforate 12a should be consistent with lamp plate 2 or slightly larger than lamp plate 2, for holding the lamp plate 2 with light source 202。During assembling, first the lamp plate 2 (or bendable circuit soft board) with light source 202 is arranged on the inner peripheral surface of fluorescent tube 1, reflectance coating 12 is sticked at fluorescent tube inner peripheral surface again, wherein the perforate 12a of reflectance coating 12 and lamp plate 2 one_to_one corresponding, outside lamp plate 2 is exposed to reflectance coating 12。

In one embodiment, the reflectance of reflectance coating 12 is at least greater than 85%, and reflecting effect is better, when being typically in more than 90%, it is therefore desirable to reach more than 95%, to obtain more preferably reflecting effect。Reflectance coating 12 occupies the 30% to 50% of whole fluorescent tube 1 circumference along the length that fluorescent tube 1 is circumferentially extending, say, that along the circumferential direction of fluorescent tube 1, 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 medium position circumferentially for lamp plate 2, say, that lamp plate 2 both sides reflectance coating 12 has the area being substantially the same, as shown in figure 17。The material of reflectance coating can be PET, strontium phosphate and barium sulfate any of which, or the wherein combination of wantonly two kinds, or the combination of three kinds, and reflecting effect is better, and thickness, between 140 μm to 350 μm, is typically between 150 μm to 220 μm, and effect is more preferably。As shown in figure 18, in other embodiments, reflectance coating 12 can only be located at the side of lamp plate 2, i.e. reflectance coating 12 and the circumferential side contacts of lamp plate 2, and the ratio that its circumference one side occupies fluorescent tube 1 circumference is similarly 0.3 to 0.5。Or, as shown in Figure 19, Figure 20, reflectance coating 12 can not offer perforate, directly reflectance coating 12 is sticked on the inner peripheral surface of fluorescent tube 1 during assembling, then being fixed on reflectance coating 12 by the lamp plate 2 with light source 202 again, reflectance coating 12 can also be circumferentially extending along fluorescent tube respectively in the one or both sides of lamp plate 2 herein。

All kinds reflectance coating 12 described in the above-described embodiments and all kinds diffusion barrier 13 can arbitrarily be arranged in pairs or groups, and can realize individually reflection, individually the optical effect of diffusion or realization reflection simultaneously and diffusion。For example, it is possible to only arrange reflectance coating 12, it is not provided with diffusion barrier 13, as shown in Figure 19, Figure 20 and Figure 21。

In other embodiments; the width of bendable circuit soft board can be widened, and owing to circuit board surface includes the circuit protecting layer of ink material, and ink material has the effect of reflection light; therefore at the position widened, circuit board itself just can play such as the effect of reflectance coating 12 function。Preferably, bendable circuit soft board is 0.3 to 0.5 along the proportion between circumferentially extending length and the girth of described fluorescent tube 2 inner peripheral surface of fluorescent tube 2。A circuit protecting layer can be coated with outside bendable circuit soft board; circuit protecting layer can be a kind of ink material; having the function increasing reflection, the bendable circuit soft board widened is with light source for starting point to circumferentially extending, and the light of light source can make light more concentrate by the position widened。

In other examples, on the inner peripheral surface of glass tubing, can all coat diffusion coating, or partly coat diffusion coating (having reflectance coating 12 part not to be coated with), but no matter it is any mode, diffusion coating to be preferably both coated onto on the outer surface of end region of fluorescent tube 1, so that the connection 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 the one in the group being made up of diffusion coating, diffusion barrier sheet, reflectance coating and adhesive film, be applied to the optical treatment of this utility model light source emitted light。

Continuing referring to Fig. 2, in this utility model one embodiment, LED straight lamp also includes bonding agent sheet 4, lamp plate insulation film 7 and light source film 8。Lamp plate 2 is pasted on the inner peripheral surface of fluorescent tube 1 by bonding agent sheet 4。Shown in figure, bonding agent sheet 4 can be silica gel, and its form is not limit, it is possible to be several sections shown in figure, or a section in strip。Various forms of bonding agent sheets 4, various forms of lamp plate insulation film 7 and various forms of light source film 8 can combine each other and constitute the difference embodiment of this utility model。

Lamp plate insulation film 7 is applied to lamp plate 2 on the surface of light source 202 so that lamp plate 2 does not expose, thus playing the insulating effect being isolated from the outside by lamp plate 2。Reserving the through hole 71 corresponding with light source 202 during gluing, light source 202 is located in through hole 71。The constituent of lamp plate insulation film 7 includes vinyl polysiloxane, hydrogen-based polysiloxanes and aluminium oxide。The thickness range of lamp plate insulation film 7 is 100 μm to 140 μm (micron)。If less than 100 μm, then do not have enough insulating effects, if greater than 140 μm, then can cause the waste of material。

Light source film 8 is applied to the surface of light source 202。The color of light source film 8 is transparent color, to ensure light transmittance。Coating is to light source 202 surface, and the shape of light source film 8 can be graininess, strip or lamellar。Wherein, the parameter of light source film 8 has refractive index, thickness etc.。What the refractive index of light source film 8 allowed ranges for 1.22～1.6, if the radical sign of opening that the refractive index of light source film 8 is light source 202 housing refractive index, or the refractive index of light source film 8 be light source 202 housing refractive index open positive and negative the 15% of radical sign, then light transmittance is better。Here light source shell refers to the housing holding LED grain (or chip)。In the present embodiment, the ranges of indices of refraction of light source film 8 is 1.225 to 1.253。The thickness range that light source film 8 allows is 1.1mm to 1.3mm, if less than 1.1mm, it will lid is light source 202 incessantly, and poor effect if greater than 1.3mm, then can reduce light transmittance, also can increase material cost simultaneously。

During assembling, first light source film 8 is applied to the surface of light source 202；Then the film 7 that insulated by lamp plate is applied on the side surface on lamp plate 2；Again light source 202 is fixed on lamp plate 2；Then a side surface opposing to lamp plate 2 and light source 202 is pasted by bonding agent sheet 4 inner peripheral surface being fixed on fluorescent tube 1；The last end region that lamp holder 3 is fixed on fluorescent tube 1 again, electrically connects light source 202 with power supply 5 simultaneously。Or as shown in figure 22, utilize bendable circuit soft board 2 to get over transition region 103 and power supply 5 welds (namely welding with power supply 5 through transition region 103), or the mode taking conventional wires routing allows lamp plate 2 and power supply 5 be electrical connected, last lamp holder 3 is connected on the transition region 103 of intensive treatment by the mode of Fig. 5 (structure with Fig. 3-Fig. 4) or Fig. 7 (by the structure of Fig. 6), 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 is sticked on the inner peripheral surface of fluorescent tube 1, so can increase the lighting angle of whole LED straight lamp, expanding angle of visibility, so arranging generally can so that angle of visibility can more than 330 degree。By being coated with lamp plate insulation film 7 at lamp plate 2, light source 202 being coated with the light source film 8 of insulation, it is achieved the insulation processing to whole lamp plate 2, such that make fluorescent tube 1 break, without there is electric shock accidents, improving safety。

Further, fluorescent tube 1 inner peripheral surface or outer peripheral face can be coated with adhesive film (not shown), for outwardly and inwardly isolating fluorescent tube 1 after fluorescent tube 1 breaks。Adhesive film is coated on the inner peripheral surface of fluorescent tube 1 by the present embodiment。

The constituent of adhesive film includes vinyl-terminated silicone fluid, containing hydrogen silicone oil, dimethylbenzene and calcium carbonate。Wherein dimethylbenzene is auxiliary agents, and after adhesive film is coated in fluorescent tube 1 inner peripheral surface and solidifies, dimethylbenzene can vapor away, and its effect mainly regulates viscosity, and then regulates the thickness of adhesive film。

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

In the present embodiment, owing to scribbling adhesive film inside fluorescent tube, after glass lamp is broken, adhesive film can by fragment adhesion together, and the through hole that through fluorescent tube is inside and outside will not be formed, thus preventing user from touching the electrical body within fluorescent tube 1, to avoid electric shock accidents, the adhesive film simultaneously adopting said ratio also has the effect of diffusion light, printing opacity, improves Luminescence Uniformity and the light transmittance of whole LED straight lamp。The adhesive film of the present embodiment can use with aforesaid bonding agent sheet 4, lamp plate insulation film 7 and light source film 8 collocation, and constitutes 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, lamp plate 2 can be any one in strip aluminium base, FR4 plate or bendable circuit soft board。Owing to the fluorescent tube 1 of the present embodiment is glass lamp, if lamp plate 2 adopts strip aluminium base or the FR4 plate of rigidity, so when fluorescent tube breaks, 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 easy to causes 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, therefore the lamp plate 2 of the present embodiment adopts bendable circuit soft board, so after fluorescent tube 1 breaks, namely cannot support the fluorescent tube 1 broken to continue to remain straight tube state, to inform that user LED straight lamp can not use, it is to avoid the generation of electric shock accidents。Therefore, after adopting bendable circuit soft board, it is possible to alleviate electric shock problem that is broken due to glass tubing and that cause to a certain extent。Namely following example 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 line layer 2a with conductive effect, and 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, stacked with line layer 2a, and the area equation of dielectric layer 2b and line layer 2a, line layer 2a is used for arranging light source 202 on the surface opposing with dielectric layer 2b。Line layer 2a is electrically connected to power supply 5 in order to allow DC current pass through。Dielectric layer 2b is then adhered on the inner peripheral surface of fluorescent tube 1 by bonding agent sheet 4 on the surface opposing with line layer 2a。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, and described circuit protecting layer can be a kind of ink material, has welding resistance and increases the function of reflection。Or, bendable circuit soft board can be a Rotating fields, is namely only made up of a sandwich circuit layer 2a, then in the circuit protecting layer of one layer of above-mentioned ink material of Surface coating of line layer 2a。Whether a sandwich circuit layer 2a structure or two-layer structure (a sandwich circuit layer 2a and one dielectric layer 2b) can coupled circuit protective layers。Circuit protecting layer can also in the side surface configuration of bendable circuit soft board, for instance only arrange circuit protecting layer in the side with light source 202。It should be noted that, bendable circuit soft board is a sandwich circuit Rotating fields 2a or is two-layer structure (a sandwich circuit layer 2a and one dielectric layer 2b), substantially ratio general three layers flexible base board (pressing from both sides one dielectric layer in two sandwich circuit layers) more pliability and flexibility, therefore, can arrange in pairs or groups (such as: non-straight lamp) with having special formed fluorescent tube 1, and bendable circuit soft board is close 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 more few, then radiating effect is more good, and material cost is more low, more environmental protection, and pliable and tough effect also has an opportunity to promote。

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

Refer to Figure 48, in one embodiment, bendable circuit soft board as lamp plate 2 from top to bottom sequentially includes a first line layer 2a, one dielectric layer 2b and one second line layer 2c, the thickness of the second line layer 2c thickness more than first line layer 2a, the length of lamp plate 2 is more than the length of fluorescent tube 1, wherein it is not provided with light source 202 at lamp plate 2 and protrudes from the stub area of fluorescent tube 1, first line layer 2a and the second line layer 2c is respectively through two through hole 203 and 204 electrical communication, but through hole 203 and 204 does not connect to avoid short circuit each other。

Thereby mode, owing to the second line layer 2c thickness is relatively big, can play the effect supporting first line layer 2a and dielectric 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, to promote fine ratio of product simultaneously。Additionally, first line layer 2a and the second line layer 2c is electrically connected logical so that the circuit layout on first line layer 2a can extend to the second line layer 2c, make the circuit layout on lamp plate 2 more polynary。Furthermore, circuit location wiring originally becomes double-deck from monolayer, and batch lamp plate quantity carrying out die bond can be increased for the line layer monolayer area on lamp plate 2, that is the size on width, it is possible to reduce further, promotes productivity ratio。

Further, lamp plate 2 is not provided with light source 202 and the first line layer 2a protruding from the stub area of fluorescent tube 1 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 directly be arranged on bendable circuit soft board and be achieved。

Continuing referring to Fig. 2, lamp plate 2 is provided with some light sources 202, is provided with power supply 5 in lamp holder 3, by lamp plate 2 electrical communication between light source 202 and power supply 5。In each embodiment of this utility model, power supply 5 can be single body (namely all power supply modules are all integrated in parts), and is located in the lamp holder 3 of fluorescent tube 1 one end；Or power supply 5 can also be divided into two parts, it is called double; two individual (namely all power supply modules are separately positioned in two parts), and two parts is respectively arranged in the lamp holder 3 of lamp tube ends。If strengthening section process is done in fluorescent tube 1 only one end, power supply prioritizing selection is single body, and is located in the lamp holder 3 corresponding to the end region after strengthening 101。

No matter it is single body or double; two individuality, the generation type of power supply can have Mutiple Choice, such as, power supply can be the module after a kind of embedding molding, specifically, uses the silica gel (heat conductivity >=0.7w/m k) of a kind of high heat conduction, by mould, power supply module is carried out embedding molding, obtain power supply, the advantage that the power supply that this mode obtains has high insulation, height dispels the heat, profile is more regular, and can coordinate with other structural members easily。Or, exposed power supply module for not do casting glue molding, directly can also be inserted inside lamp holder by power supply, or after the exposed power supply module conventional thermal draw is encased, then it is internal to insert lamp holder 3。In other words, in each embodiment of this utility model, power supply 5 can be the form appearance carrying power supply module as shown in figure 23 with monolithic printed circuit board (PCB), also can be occur with the form of single module as shown in figure 38。

Refer to Fig. 2 and in conjunction with Figure 38, in an embodiment, one end of power supply 5 has male plug 51, and the other end has metal ferrule 52, and the end of lamp plate 2 is provided with female plug 201, and lamp holder 3 is provided with the hollow conductive pin 301 for connecting external power source。The male plug 51 of power supply 5 is inserted in the female plug 201 of lamp plate 2, and metal ferrule 52 is inserted in the hollow conductive pin 301 of lamp holder 3。Now male plug 51 and female plug 201 are equivalent to adaptor, for power supply 5 and lamp plate 2 being electrically connected。When metal ferrule 52 inserts after in hollow conductive pin 301, impact hollow conductive pin 301 through outside stamping tool so that slight deformation occurs hollow conductive pin 301, thus the metal ferrule 52 fixed on power supply 5, and realize electrical connection。During energising, electric current passes sequentially through hollow conductive pin 301, metal ferrule 52, male plug 51 and female plug 201 and arrives lamp plate 2, and arrives light source 202 by lamp plate 2。But, the structure of power supply 5 is then not limited to modular pattern shown in Figure 38。Power supply 5 can be a printed circuit board (PCB) being loaded with power supply module, then is electrically connected with connected mode and the lamp plate 2 of male plug 51, female plug 201。

In other embodiments, electric connection between power supply 5 and the lamp plate 2 of any pattern can also replace above-mentioned male plug 51 and female plug 201 by conventional wires routing mode, namely adopting a traditional plain conductor, electrically connected with power supply one end of plain conductor, the other end electrically connects with lamp plate 2。Further, plain conductor can be coated with an insulated sleeve to protect user to avoid getting an electric shock。But the mode that wire routing connects likely has the problem of fracture in transportation, slightly worse in quality。

In other embodiments, the electric connection between power supply 5 with lamp plate 2 can be bondd by rivet nail joint, tin cream, welds or be directly linked together in the way of wire binding。Consistent with the fixed form of aforementioned lamp plate 2, a side surface of bendable circuit soft board is bonded and fixed to the inner peripheral surface of 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 and female plug 201 is set on bendable circuit soft board, then the male plug 51 of power supply 5 is inserted female plug 201 and realizes electrical connection。

If lamp plate 2 is not fixed on the inner peripheral surface of fluorescent tube 1 along the two ends that fluorescent tube 1 is axial, if adopting wire to connect, moving in process follow-up, due to two ends freely, process being susceptible to rock in follow-up moving, thus making it possible to wire and rupture。Therefore lamp plate 2 with the connected mode prioritizing selection of power supply 5 for welding。Specifically, with reference to Figure 22, it is possible to be welded on the outfan of power supply 5 after directly lamp plate 2 is got over the transition region 103 of strengthening section structure, remove the use of wire from, improve the stability of product quality。Now lamp plate 2 need not arrange female plug 201, and the outfan of power supply 5 is also without arranging male plug 51。

As shown in figure 24, the concrete practice can be that the outfan of power supply 5 is reserved power pad a, and on power pad a, stay stannum so that the thickness of stannum on pad increases, convenient welding, accordingly, the end of lamp plate 2 also reserves light source pad b, and the light source pad b of the power pad a of power supply 5 outfan Yu lamp plate 2 is welded together。It is front by the plane definition at pad place, then lamp plate 2 docks the most firm with the connected mode of power supply 5 with the pad in both fronts, but welding pressure head must be pressed in the back side of lamp plate 2 when welding, scolding tin is heated across lamp plate 2, the problem being easier reliability occurs。If as shown in figure 30, will output hole, then weld on the power pad a being superimposed upon power supply 5 front that faced up in the middle of the light source pad b in lamp plate 2 front, then scolding tin heating can directly be melted by welding pressure head, to being relatively easy on Practical Operation realize。

As shown in figure 24, in above-described embodiment, bendable circuit soft board major part as lamp plate 2 is fixed on the inner peripheral surface of fluorescent tube 1, it is be not only 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 forms a 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 5 welding can drive freedom portion 21 to fluorescent tube 1 internal contraction。It should be noted that, when the bendable circuit soft board as lamp plate 2 has two sandwich circuit layer 2a and the 2c structure pressing from both sides a dielectric layer 2b as shown in figure 48, aforementioned lamp plate 2 is not provided with light source 202 and protrudes from the stub area of fluorescent tube 1 and as freedom portion 21, and freedom portion 21 can be allowed to realize the connection of two sandwich circuit layers and the circuit layout of power supply module。

In the present embodiment, when lamp plate 2 and power supply 5 connect, the surface, light source 202 place on pad b and a and lamp plate in the same direction, and is formed with through hole e as shown in figure 30 on the pad b on lamp plate 2 so that pad b and pad a is interconnected。When the freedom portion 21 of lamp plate 2 deforms towards the internal contraction of fluorescent tube 1, power supply 5 is had a lateral pulling force by the welded connection between printed circuit board (PCB) and the lamp plate 2 of power supply 5。Further, compared to the aspectant situation of pad b system on the pad a of power supply 5 and lamp plate 2, power supply 5 is also had a downward pulling force by the welded connection between printed circuit board (PCB) and the lamp plate 2 of power supply 5 here。This downward pulling force comes from the solder in through hole e and forms one between power supply 5 and lamp plate 2 and more strengthen and be firmly electrically connected。

As shown in figure 25, the light source pad b of lamp plate 2 is two unconnected pads, electrically connects with light source 202 both positive and negative polarity respectively, and the size of pad is about 3.5 × 2mm², the printed circuit board (PCB) of power supply 5 also has pad corresponding thereto, being arranged above of pad is easy to welding board automatic welding and is had reserved stannum, and the thickness of stannum can be 0.1 to 0.7mm, it is advantageous to value is that 0.3 to 0.5mm is comparatively appropriate, with 0.4mm for the best。One insulation hole c can be set between two pads, two pads are avoided to cause electrical short in the process of welding because scolding tin is welded together, the rear of this external insulated hole hole c also can arrange location hole d, is used for the tram allowing automatic welding board can correctly judge light source pad b。

The light source pad b of lamp plate has at least one, electrically connects with light source 202 both positive and negative polarity respectively。In other embodiments, in order to be able to reach the extendibility in compatible and follow-up use, the quantity of light source pad b can have more than one, for instance 2,3,4 or more than 4。When pad only has 1, corresponding two ends of lamp plate all can electrically connect with power supply respectively, to form primary Ioops, and the mode that now available electronic building brick replaces, for instance: replace electric capacity with inductance and be used as current stabilization assembly。If Figure 26 is to shown in 28, when pad is 3, the 3rd pad can serve as ground connection and use, and when pad is 4, the 4th pad can be used to make signal input end。Accordingly, power pad a is also identical with light source pad b quantity。When pad is more than 3, the arrangement between pad side by side or can line up two row for string, configuring in position according to accommodating size time actually used, causing short circuit as long as not electrically connecting each other。In other embodiments, if by part circuit production on bendable circuit soft board, light source pad b can be independent one, and number of pads is fewer, more saves flow process in technique；The more, the electrical connection of bendable circuit soft board and power output end is fixing more to be strengthened number of pads。

As shown in figure 30, in other embodiments, the inside of light source pad b can have the structure of welding perforation e, and the diameter of welding perforation e can be 1 to 2mm, it is advantageous to being 1.2 to 1.8mm, the best is 1.5mm, too little, and the stannum welded not easily passes through。When the power pad a of the power supply 5 and light source pad b of lamp plate 2 welds together, the stannum of welding can pass described welding perforation e, then it is deposited in cooling above welding perforation e to condense, form the ball structure g having more than welding perforation e diameter, it seems the function of nail that this ball structure g can play, except fixing through the stannum between power pad a and light source pad b, more can strengthen the firm fixed of electric connection because of the effect of ball structure g。

As shown in Figure 31 to Figure 32, in other embodiments, as the edge≤1mm of the welding perforation e distance lamp plate 2 of light source pad b, the stannum of welding can pass described hole e and be deposited in hole top edges, too much stannum also can reflux from the edge of lamp plate 2 toward lower section, then, together with condensing in the stannum on power pad a, its structure similarly is that lamp plate 2 is followed closely on the circuit board of power supply 5 by a rivet firmly, has reliable electricity connection function。As shown in Figure 33 and Figure 34, in other embodiments, welding breach f instead of welding perforation e, the welding perforation of pad is at edge, the stannum of welding electrically connects power pad a and light source pad b fixing through described welding breach f, stannum is easier to climb up light source pad b and is deposited in around welding breach f, forms, when cooling has more stannum after condensing, the soldered ball having more than welding breach f diameter, and this ball structure can allow the crystallized ability of electric connection structure strengthen。In the present embodiment, because the design of welding breach, it seems the sub function of C staple that the stannum of welding plays。

The welding perforation of pad is whether initially formed, or directly punches with welding pressure head as shown in figure 40 or title thermal head in the process of welding, can reach the structure described in the present embodiment。Described welding its surface contacted with scolding tin of pressure head can be plane, concave surface, convex surface or these combinations；And described welding pressure head can for strip or latticed for limiting the surface being intended to welding object such as lamp plate 2, perforation is not exclusively covered by the described surface contacted with scolding tin, guarantee that scolding tin can pass from perforation, when scolding tin pass welding perforation be deposited in welding perforation around time, recess is provided that the accommodating position of soldered ball。In other embodiments, the bendable circuit soft board as lamp plate 2 has a hole, location, can pass through hole, location when welding and be positioned accurately by the pad of power pad a and light source pad b。

Refer to Figure 40, in above-described embodiment, the light source pad b of the lamp plate 2 and power pad a of power supply 5 can pass through welding manner and fixes, and the perforation of pad is whether initially formed, or is directly punch with welding pressure head 41 in the process of welding。As shown in figure 40, described welding pressure head 41 is substantially divided into four regions: pressure welding face 411, guiding gutter 412, stannum grooving 413 and press face 414, pressure welding face 411 is the surface that contacts actual in scolding tin, pressure when welding and heating source are provided, its shape can be plane or concave surface or convex surface or above combination, press face 414 is the surface contacted with welding object such as lamp plate 2 reality, it can be strip or latticed, hole on pad will not be covered by described pressure welding face 411 completely, part at the welding pressure head 41 intermediate pressure face of weld 411 lower edge has the guiding gutter 412 that a plurality of circular arc is recessed, namely its major function is to ensure that the scolding tin that 411 heating melt through pressure welding face can flow through hole or the breach of pad from recessed diversion space, therefore, guiding gutter 412 has water conservancy diversion and the function of backstop (stopper), when scolding tin passes hole or breach is deposited in around its surface, it is positioned at stannum grooving 413 more recessed than guiding gutter 412 below guiding gutter 412 and is the accommodating position providing scolding tin to condense into soldered ball。It is additionally then press face 414 in the plane that grooving 413 periphery is slightly lower than pressure welding face 411, its height thickness difference with pressure welding face 411 is the thickness of lamp plate 2, and major function is exactly can really lamp plate 2 compacting be fixed on the printed circuit board (PCB) of power supply 5 in the process of welding。

Refer to Figure 41, Figure 25 and Figure 40, lamp plate 2 and the printed circuit board (PCB) of power supply 5 also there is pad corresponding thereto, being arranged above of pad is easy to welding board automatic welding and is had reserved stannum, it is however generally that the thickness preferred values of stannum is that lamp plate 2 then can be firmly welded on the printed circuit board (PCB) of power supply 5 by 0.3 to 0.5mm。If occurring as shown in Figure 41; when on two pads, the thickness difference of reserved stannum is too big; welding pressure head 41 presses through in journey in weldering; the a pad reserved stannum of first contact will be occurred to add heat fusing; another reserved stannum just can start fusing after waiting aforementioned reserved stannum to be melted to identical height and being soldered pressure head 41 contact, so, and that pad that reserved stannum thickness is relatively low; often can there is the situation that not prison welding is leaned on, and then the printed circuit board (PCB) having influence on lamp plate 2 and power supply 5 is electrically connected。Therefore, the present embodiment is applied dynamically balanced principle and is solved this situation。In the present embodiment, can arranging an interlinked mechanism on the equipment of welding pressure head 41, initiating welding pressure head 41 is a rotating mechanism, when weld pressure head 41 contact and detect on two pads the force value of reserved stannum identical time, bestow again and press through journey, above-mentioned situation can be solved。

In above-described embodiment, it is motionless with the printed circuit board (PCB) of power supply 5 with lamp plate 2, and the dynamic balance principle rotating the welding pressure head 41 of welding board presses through journey reaching weldering, in other embodiments, as shown in figure 42, it is then that to weld pressure head 41 motionless, and the dynamic balance principle rotating lamp plate 2 presses through journey to reach weldering。First, first the printed circuit board (PCB) of lamp plate 2 with power supply 5 is positioned in a carrier device (or claiming to weld carrier) 60, carrier device 60 includes a lamp plate carrier (or claiming rotation platform) 61 in order to carry the printed circuit board (PCB) of lamp plate 2 and power supply 5, and a carrier support 62 is in order to carry lamp plate carrier 61。Lamp plate carrier 61 includes a rotation axle 63 and two elastic partss 64 are respectively arranged on rotation axle two side in order to keep lamp plate carrier 61 to be the level of state when lamp plate carrier 61 is unloaded。In the present embodiment, elastic parts 64 is spring, and one end of spring is respectively arranged on carrier support 62 as fulcrum, when having the lamp plate 2 of reserved stannum of two limit variable thickness shown in Figure 42 and being placed on lamp plate carrier 61, lamp plate carrier 61 can be subject to rotate axle 63 and drive and rotate, until welding pressure head 41 detect the pressure of the reserved stannum in two limits equal time, just can start to perform weldering and press through journey, as shown in figure 43, a now pulling force and a pressure after elastic parts 64 difference of rotation axle two side, when weldering presses through after journey completes, namely the driving force rotating axle 63 can remove, and make lamp plate carrier 61 be returned to original level by the restoring force of elastic parts 64 rotating axle 63 2 side。

Certainly, the lamp plate carrier 61 of the present embodiment can also the mechanism of other modes be reached, and not necessarily need to rotate axle 63 and elastic parts 64, such as in the built-in driving motor of lamp plate carrier 61, active rotating mechanism etc., now carrier support 62 (effect of fixed elastic parts 64) also inessential assembly, all utilize dynamically balanced principle and drive the mode that lamp plate 2 rotates to reach weldering and press through the change case of journey, all without departing from the category of this utility model, then repeat no more below。
