For enabling above-mentioned purpose of the present utility model, feature and advantage more become apparent, and are described in detail specific embodiment of the utility model below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of LED daylight lamp, with reference to Fig. 1-2, comprising: fluorescent tube 1, the lamp plate 2 be located in fluorescent tube 1, and two lamp holders 3 being located at fluorescent tube 1 two ends respectively.Wherein fluorescent tube 1 can adopt plastics fluorescent tube or glass lamp, and the present embodiment adopts the glass lamp of tool strengthening section, easily breaks and the electric shock accidents caused because of electric leakage that breaks to avoid traditional glass fluorescent tube, and the problem that plastics fluorescent tube is easily aging.
The mode of fluorescent tube strengthening can make chemically or physics mode does secondary operations strengthening to glass, the general principle of chemical mode improves the intensity of glass, the Na ion with other alkali metal ion and surface layer of glass that its method is or K ion exchange, surface forms ion exchange layer, after being cooled to normal temperature, glass is in internal layer tension, the state of outer pressurized, thus reach the object of gaining in strength, include but not limited to high temperature modification ion-exchange, low form ion-exchange, dealkalize method, surface crystallization method, sodium metasilicate reinforcement etc.
1, high temperature modification ion-exchange
In the temperature province between the softening point and transition point of glass, containing Na
2o or K
2the glass of O invades in the fused salt of lithium, Na ion in glass or the Li Ion Phase in the fused salt little with their radiuses are exchanged, are then cooled to room temperature, due to containing Li ion top layer with contain Na ion or K ion inner layer expansion coefficient different, surface produces residual pressure and strengthens, simultaneously; Glass neutralization is containing Al
2o3, TiO
2deng composition time, by ion-exchange, can produce the crystallization that the coefficient of expansion is extremely low, cooled glass surface will produce very large pressure, can obtain the glass of intensity up to 700MPa.
2, low form ion-exchange
Low-temperature ion exchange process is in the humidity province lower than strain point of glass, do ion-exchange with monovalent cation (as K ion) and Na ion than top layer basic ion (as Na ion) also larger ionic radius, make K ion enter the method on top layer.Such as Na
2o+CaO+SiO
2system glass, can flood tens hours in the fuse salt of degree more than 400.Low form ion-exchange can be easy to obtain high strength, has processing method and simply, does not damage the features such as the glass surface transparency, constant row.
3, dealkalize method
Dealkalize method is in the high-temperature atmosphere containing sulphurous acid gas and moisture, utilizes Pt catalyst treatment glass, Na+ ion is oozed out from surface layer of glass and reacts with sulfurous acid, thus superficial layer becomes rich SiO
2layer, its result becomes low expansion glass due to top layer, produces compression during cooling
4, surface crystallization method
Surface crystallization method is different from high temperature modification ion-exchange, but forms low-expansion microcrystal by means of only heat treatment on top layer, thus makes it the method for strengthening.
5, sodium metasilicate reinforcement
Sodium metasilicate reinforcement processes in the aqueous solution of sodium metasilicate (waterglass) under several atmospheric pressure more than 100 degrees Celsius, thus obtain the high strength glass being difficult to scuffing top layer.
Physics mode does glass to be strengthened, and can include but not limited to, uses the mode of coating or changes the structure of article.The matrix that coating sprays as required determines kind and the state of coating, can be ceramic tile strengthened coat, acrylic coating or glass coating etc., can be liquid or gaseous state coating when being coated with.Change the structure of article, such as, do structural strengthening design in part of easily breaking.No matter be that chemical mode or physics mode are not limited to single mode and implement above, any one that can mix in physics mode or in chemical mode does any matched combined.
The present embodiment explains with structure-reinforced design, and fluorescent tube 1 comprises main body 102 and lays respectively at the end 101 at main body 102 two ends, and lamp holder 3 is sheathed on outside end 101.Wherein, the external diameter of at least one end 101 is less than the external diameter of main body 102.In the present embodiment, the external diameter arranging two ends 101 is all less than the external diameter of main body 102.Particularly, the two ends of fluorescent tube 1 are by strengthening section process, and end 101 forms strengthening section structure, lamp holder 3 is enclosed within the end 101 after strengthening, the difference of lamp holder 3 external diameter and lamp tube main body 102 external diameter can be made like this to diminish, and even completely equal, namely lamp holder 3 external diameter is equal with main body 102 external diameter.The benefit of such setting is, in transportation, packaging support only can not contact lamp holder 3, it can contact lamp holder 3 and fluorescent tube 1 simultaneously, making whole LED daylight lamp uniform force, and lamp holder 3 can not be made to become unique stress point, concentratedly to break due to stressed in the position avoiding lamp holder 3 to be connected with lamp tube end 101, improve the quality of product, and have effect attractive in appearance concurrently.
In the present embodiment, lamp holder 3 external diameter is substantially equal with main body 102 external diameter, and tolerance is in positive and negative 0.2mm (millimeter), is no more than at most positive and negative 1mm.
In order to reach the lamp holder 3 external diameter object substantially equal with main body 102 external diameter, according to the thickness of different lamp holders 3, the end 101 after strengthening can be 1mm ~ 10mm with the difference range of main body 102 external diameter; Or preferred, the end 101 after strengthening can be relaxed to 2mm ~ 7mm with the difference range of main body 102 external diameter.
In the present embodiment, with reference to Fig. 3, seamlessly transit, form a transition part 103 between the end 101 of fluorescent tube 1 and main body 102, transition part 103 is in cambered surface, and namely transition part 103 section is vertically arc shaped.
The length of transition part 103 is 1mm ~ 4mm, if be less than 1mm, then and the insufficient strength of transition part; If be greater than 4mm, then can reduce the length of main body 102, reduce light-emitting area, need the corresponding increase of the length of lamp holder 3 to coordinate with main body 102 simultaneously, cause the material of lamp holder 3 to increase.In other embodiments, then transition part 103 also can not be arc.
For the standard fluorescent tube of T8, the external diametrical extent of the end 101 after strengthening is 20.9mm ~ 23mm, if be less than 20.9mm, then the internal diameter of end 101 is too small, causes power supply unit cannot insert in fluorescent tube 1.The external diametrical extent of main body 102 is 25mm ~ 28mm, if be less than 25mm, then with existing process conditions, inconvenience does strengthening section process to its two ends, if be greater than 28mm, will not meet professional standard.
Continue with reference 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.
Wherein, 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 also can be divided into two parts, be called two individual (namely all power supply modules are separately positioned in two parts), and two parts be located at respectively in the lamp holder 3 of lamp tube ends.If when fluorescent tube 1 only has one end to do strengthening section process, power supply prioritizing selection is single body, and be located in the lamp holder 3 corresponding to the end after strengthening 101.
No matter be single body or two individuality, the generation type of power supply can have Mutiple Choice, such as, power supply can be a kind of embedding shaping after module, particularly, use a kind of silica gel (thermal conductivity factor >=0.7w/mk) of high heat conduction, by mould, embedding is carried out to power supply module shaping, obtain power supply, the power supply that this mode obtains has the advantage that height insulate, height dispels the heat, profile is more regular, and can coordinate with other structural members easily.Or power supply also can be shaping for not making casting glue, directly exposed power supply module inserted lamp holder inside, or after being encased with traditional heat-shrink tube by exposed power supply module, then insert lamp holder 3 inside.
In general, with reference to Fig. 2 composition graphs 4-6, one end of power supply 5 has male plug 501, and the other end has metal ferrule 502, 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 501 of power supply 5 is inserted in the female plug 201 of lamp plate 2, and metal ferrule 502 is inserted in the hollow conductive pin 301 of lamp holder 3.Now male plug 501 and female plug 201 are equivalent to adapter, for power supply 5 and lamp plate 2 being electrically connected.When metal ferrule 502 inserts after in hollow conductive pin 301, impact hollow conductive pin 301 through outside stamping tool, make hollow conductive pin 301 that slight distortion occur, thus fix the metal ferrule 502 on power supply 5, and realize electrical connection.
During energising, electric current arrives lamp plate 2 by hollow conductive pin 301, metal ferrule 502, male plug 501 and female plug 201 successively, and arrives light source 202 by lamp plate 2.In other embodiments, the connected mode of male plug 501, female plug 201 can not be adopted, and can replace by conventional wires routing mode, namely the plain conductor that traditional is adopted, one end of plain conductor is connected with power electric, the other end is electrically connected with lamp plate 2, but the mode that wire routing connects is likely in the problem having fracture in transportation, slightly poor qualitatively.
Conveniently being connected and fixed of lamp holder 3 and fluorescent tube 1, the present embodiment improves for lamp holder 3.
With reference to Fig. 4-5 composition graphs 7-9, lamp holder 3 be sheathed on fluorescent tube 1 outer time, lamp holder 3 is sheathed on outside end 101, and extends to transition part 103, partly overlaps with transition part 103.
Lamp holder 3, except hollow conductive pin 301, also comprises insulation tube 302, and is fixedly arranged on the heat-conducting part 303 on insulation tube 302 outer peripheral face, and its hollow core conductive pin 301 is located on insulation tube 302.Insulation tube 302 one end towards fluorescent tube is stretched out in one end of heat-conducting part 303, bonding by PUR 6 between the extension (stretching out the part of insulation tube) of heat-conducting part 303 and fluorescent tube 1.In the present embodiment, lamp holder 3 extends to transition part 103 by heat-conducting part 303, and insulation tube 302 does not extend to transition part 103 towards one end of fluorescent tube 1, and namely insulation tube 302 has interval towards between one end and transition part 103 of fluorescent tube.
PUR 6 (comprising a kind of material be commonly called as welding powder) composition is mainly: phenolic resins 2127#, shellac, rosin, calcite in powder, zinc oxide, ethanol etc.PUR 6 can occur significantly to expand under the condition of high-temperature heating, adds the stickiness of material own, thus can make lamp holder 3 and fluorescent tube 1 close contact, is convenient to LED daylight lamp and realizes automated production.In addition, because PUR 6 is thermosetting cement, reliability decrease can not be caused because the heating element heatings such as power supply module form hot environment, can prevent fluorescent tube 1 and the adhesive property of lamp holder 3 in LED daylight lamp use procedure from reducing, improve long-term reliability.
Particularly, between PUR 6 inner surface that is filled in heat-conducting part 303 extension and the outer peripheral face of fluorescent tube 1 (in figure position shown in dotted line B).PUR 6 coating thickness can be 0.2mm ~ 0.5mm, and after solidification, PUR 6 can expand, thus contacts with fluorescent tube 1 and lamp holder 3 is fixed on fluorescent tube 1.And between outer peripheral face due to both end 101 and main body 102, there is difference in height, PUR therefore can be avoided to spill in main body 102 part of fluorescent tube, remove follow-up manual wipping process from, improve the output of LED daylight lamp.
Add man-hour, by external heat equipment by heat conduction to heat-conducting part 303, and then conduct to PUR 6, make PUR 6 expansion curing, thus lamp holder 3 is fixedly bonded on fluorescent tube 1.
In the present embodiment, insulation tube 302 comprises the first pipe 302a and the second pipe 302b that connect vertically, and the external diameter of the second pipe 302b is less than the external diameter of the first pipe 302a, and the external diameter difference range of two pipes is 0.15mm ~ 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 is concordant with the outer peripheral face of the first pipe 302a, makes the outer surface flat smooth of lamp holder 3, ensures whole LED daylight lamp uniform force in packaging, transportation.Wherein, heat-conducting part 303 compares for 1:2.5 ~ 1:5, i.e. heat-conducting part length along the length of lamp holder axial direction and the axial length of insulation tube 302: insulation tube length is 1:2.5 ~ 1:5.
In order to ensure bonding fastness, the present embodiment arranges the second pipe 302b and is sheathed on outside fluorescent tube 1 at least partly, PUR 6 have be partially filled in overlapped (in figure position shown in dotted line A) between the second pipe 302b and fluorescent tube 1, between the two also by PUR 6 bonding.During manufacture, when during coating hot-melt adhesive 6, the amount of PUR suitably can be increased between heat-conducting part 303 and end 101, make in the process of subsequent heat, PUR can flow to due to expansion between the second pipe 302b and end 101, and then both are bonded connection.
Wherein, after the end 101 of fluorescent tube 1 is inserted in lamp holder 3, the axial length that lamp holder 3 part is inserted in the end 101 of fluorescent tube 1 account for heat-conducting part 303 axial length 2/1 to three/3rds between, such benefit is: on the one hand, ensure 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, the creep age distance between hollow conductive pin 301 and heat-conducting part 303 being strengthened, getting an electric shock and the test of initiation potential more easily by making people during high voltage.
Further, PUR 6, the second pipe 302b for the second pipe 302b inner surface 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.Therefore, with reference to Fig. 5, the present embodiment arranges multiple breach 302c 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, being beneficial to heat conducts to PUR 6 from heat-conducting part 303 fast, accelerates the solidification 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, can not get an electric shock because fluorescent tube 1 has breakage.
Wherein, heat-conducting part 303 can be the material of various easy heat conduction, is sheet metal, and has consideration attractive in appearance concurrently, such as aluminium alloy in the present embodiment.Heat-conducting part 303 is (or claiming ring-type) in a tubular form, is set in outside the second pipe 302b.Insulation tube 302 can be various insulating materials, but is good to be not easy heat conduction, avoid heat conduction on the power supply module of lamp holder 3 inside, affect the performance of power supply module, the insulation tube 302 in the present embodiment is plastic tube.
In other embodiments, heat-conducting part 303 can also be made up of along the second pipe 302b circumference interval or not spaced sheet metal multiple.

Light source glue 8 is applied to the surface of light source 202.The color of light source glue 8 is Transparent color, to ensure light transmittance.After being coated to light source 202 surface, the shape of light source glue 8 can be graininess, strip or sheet.Wherein, the parameter of light source glue 8 has refractive index, thickness etc.The scope that the refractive index of light source glue 8 allows is 1.22 ~ 1.6, if the refractive index of light source glue 8 be light source 202 housing refractive index open radical sign, or the refractive index of light source glue 8 be light source 202 housing refractive index open positive and negative 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 glue 8 is 1.225 ~ 1.253.The thickness range that light source glue 8 allows is 1.1mm ~ 1.3mm, if be less than 1.1mm, will cover incessantly light source 202, poor effect, if be greater than 1.3mm, then can reduce light transmittance, also can increase material cost simultaneously.
During assembling, first light source glue 8 is applied to the surface of light source 202; Then lamp plate insulating cement 7 is applied to side on lamp plate 2 on the surface; 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 4 inner peripheral surface being fixed on fluorescent tube 1; The last end again lamp holder 3 being fixed on fluorescent tube 1, is electrically connected light source 202 with power supply 5 simultaneously.Or utilize flexible base board to get over transition part 103 and power solder (namely welding with power supply 5 through transition part 103) as Figure 10, or take the mode of conventional wires routing to allow lamp plate 2 and power supply 5 be electrical connected, last lamp holder 3 is connected on the transition part 103 at strengthening section place by the mode of Fig. 7 (structure with Fig. 4-5) or Fig. 8 (structure with Fig. 9), forms a complete LED daylight lamp.
In the present embodiment, lamp plate 2 is fixed on the inner peripheral surface of fluorescent tube 1 by bonding agent 4, makes light source 202 be sticked on the inner peripheral surface of fluorescent tube 1, can increase the lighting angle of whole LED daylight lamp like this, expand angle of visibility, arrange like this and generally can make angle of visibility can more than 330 degree.By being coated with lamp plate insulating cement 7 at lamp plate 2, light source 202 being coated with the light source glue 8 of insulation, realizing the insulation processing to whole lamp plate 2, like this, even if fluorescent tube 1 breaks, also electric shock accidents can not occur, improve security.
Further, lamp plate 2 can be any one in flexible base board, strip aluminium base or FR4 plate.Because 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 still can remain the state of straight tube, at this moment user likely can think that LED daylight lamp can also use and go to install voluntarily, easily causes electric shock accidents.Therefore the lamp plate of the present embodiment adopts flexible base board, like this after fluorescent tube breaks, because flexible base board is flexible state, the fluorescent tube broken cannot be supported and continue to remain straight tube state, to inform that user's LED daylight lamp can not use, avoid the generation of electric shock accidents.Therefore, when after employing flexible base board, the contact problems caused due to glass tube fragmentation can be alleviated to a certain extent.Namely following examples explain using flexible base board as the utility model lamp plate 2.
Wherein, can be connected by wire routing between flexible base board and the output of power supply 5, or connect through male plug 501, female plug 201, or, by being welded to connect.Consistent with the fixed form of aforementioned lamp plate 2, a side surface of flexible base board is bonded and fixed to the inner peripheral surface of fluorescent tube 1 by bonding agent 4, and the two ends of flexible base board can be selected fixing or not be fixed on the inner peripheral surface of fluorescent tube 1.
If the two ends of flexible base board are not fixed on the inner peripheral surface of fluorescent tube 1, if adopt wire to connect, move in process follow-up, because two ends are free, easily shake in follow-up moving in process, thus likely make wire rupture.Therefore flexible base board and the connected mode prioritizing selection of power supply are for welding, particularly, with reference to Figure 10, be welded on the output of power supply 5 after directly flexible base board can being got over the transition part 103 of strengthening section structure, remove the use of wire from, the stability of improving the quality of products.Now flexible base board does not need to arrange female plug 201, the output of power supply 5 does not need to arrange male plug 501 yet, the concrete practice can be that the output of power supply 5 is reserved pad a, and on pad a, stay tin, to make the thickness of the tin on pad increase, convenient welding, accordingly, the end of flexible base board also reserves pad b, and the pad a of power output end and the pad b of flexible base board is welded together.
The pad b of flexible base board has two unconnected weld pads, is electrically connected respectively with light source 202 both positive and negative polarity.In other embodiments, in order to the extendibility in compatible and follow-up use can be reached, the quantity of pad b can have plural weld pad, such as 3, more than 4 or 4, when weld pad is 3,3rd weld pad can be used as ground connection use, and when weld pad is 4, the 4th weld pad can be used for signal input end.Accordingly, pad a also leaves the weld pad identical with pad b quantity.When weld pad is more than 3, the arrangement between weld pad can be row side by side or line up two row, according to accommodating size configuration during actual use in position, cause short circuit as long as be not electrically connected each other.In other embodiments, if by part circuit production on flexible substrates, pad b only can have an independent weld pad, and weld pad quantity is fewer, and technique is more saved flow process; The more, the electrical connection of flexible base board and power output end is fixing more to be strengthened weld pad quantity.
In other embodiments, the inside of pad b weld pad can have perforation, when the pad b of pad a and flexible base board welds together, the tin of welding can pass described perforation, when tin passes perforation, perforation can be deposited in around, when after cooling, can form the soldered ball having and be greater than penetration hole diameter, it similarly is the function of nail that this ball structure can play, except fixing through the tin between pad a and pad b, more can form the fixing enhancing of structural electrical connection because of the effect of soldered ball.
In other embodiments, the perforation of weld pad is at edge, namely weld pad has a breach, and the tin of welding is electrically connected pad a and pad b fixing through described breach, and tin can be deposited in perforation around, when after cooling, can form the soldered ball having and be greater than penetration hole diameter, this ball structure can form the fixing enhancing of structural electrical connection, in the present embodiment, because the design of breach, it similarly is the function of ㄇ staple that the tin of welding plays.
No matter the perforation of weld pad is first formed, or in the process of welding, direct pressure-welding head is punched, and can reach the structure described in the present embodiment.Its surface contacted with scolding tin of described pressure-welding head can be plane or the surface with recess and protuberance, protuberance can be strip or latticed, perforation not exclusively covers by described protuberance, guarantee that scolding tin can pass from perforation, when scolding tin pass perforation be deposited in perforation around time, recess can provide the accommodating position of soldered ball.In other embodiments, flexible base board has a locating hole, can locate accurately when welding through the weld pad of locating hole by pad a and pad b.
In above-described embodiment, flexible base board major part is fixed on the inner peripheral surface of fluorescent tube 1, only be not fixed on the inner peripheral surface of fluorescent tube 1 at two ends, the flexible base board be not fixed on fluorescent tube 1 inner peripheral surface forms a freedom portion, when assembling, one end of freedom portion and power solder can drive freedom portion to fluorescent tube internal contraction, the freedom portion of flexible base board can be out of shape because of contraction, use the above-mentioned flexible base board with perforation weld pad, the pad a of side and power solder that flexible base board has light source is towards the same side, when the freedom portion of flexible base board is out of shape because of contraction, one end of flexible base board and power solder is the pulling force having a side direction to power supply, pad a compared to side and power solder that flexible base board has light source is towards the welding of not the same side, one end of flexible base board and power solder also has a downward pulling force to power supply, use the above-mentioned flexible base board with perforation weld pad, formed structural electrical connection fix strengthen there is better effect.
If the two ends of flexible base 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 flexible substrates, then the male plug 501 of power supply 5 is inserted female plug 201 and realize electrical connection.
Wherein, flexible base board comprises at least one conductive layer, and light source is located on conductive layer, is communicated with power sourced electric by conductive layer.With reference to Figure 11, in the present embodiment, flexible base board comprises stacked conductive layer 2a and dielectric layer 2b, and conductive layer 2a is used for arranging light source 202 on the surface opposing with dielectric layer 2b, and dielectric layer 2b is then adhered to by bonding agent 4 on the inner peripheral surface of fluorescent tube 1 on the surface opposing with conductive layer 2a.Wherein, conductive layer 2a can be metal level, or is furnished with the bus plane of wire (such as copper cash).
Flexible base board also can be stacked three-decker, three-decker comprises two conductive layers, and the dielectric layer between two conductive layers, now only need wherein to be used for arranging light source by one deck conductive layer, another layer of conductive layer is fixed on the inner peripheral surface of fluorescent tube.In other embodiments, under the anticreep measure of guarantee meets the requirements of situation, the setting of dielectric layer can be saved, directly conductive layer is adhered on the inner peripheral surface of fluorescent tube.In other embodiments, can a coated circuit protecting layer outside conductive layer and dielectric layer, described circuit protecting layer can be a kind of ink material, has welding resistance and increases the function of reflection.No matter be one deck conductive layer, two-layer structure, three-decker can coupled circuit protective layer.Circuit protecting layer also can be arranged in the side of flexible base board, such as, only arrange circuit protecting layer in the side with light source 202.It should be noted that in the present embodiment, flexible base board is close to tube wall for preferably to configure, and the number of plies of flexible base board is fewer, then radiating effect is better, and material cost is lower.
Further, fluorescent tube 1 inner peripheral surface or outer peripheral face are coated with adhesive film (not shown), for isolating the outside of fluorescent tube 1 and inside after fluorescent tube 1 breaks.Adhesive film is coated on the inner peripheral surface of fluorescent tube 1 by the present embodiment.

Wherein dimethylbenzene is auxiliary agents, and after adhesive film is coated in fluorescent tube inner peripheral surface and solidifies, dimethylbenzene can vapor away, and it acts on mainly adjusting viscosity, and then regulates the thickness of adhesive film.
In the present embodiment, the thickness range of adhesive film is 100 μm ~ 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 is greater than 140 μm and then can reduces light transmittance, and increases material cost.If explosion-proof performance and light transmittance requirement are comparatively loose, then the thickness range of adhesive film also can relax to 10 μm ~ 800 μm.
In the present embodiment, because fluorescent tube inside scribbles adhesive film, after glass lamp fragmentation, adhesive film can by fragment adhesion together, and the through hole that through fluorescent tube is inside and outside can not be formed, thus prevent user from touching the electrical body of fluorescent tube inside, to avoid electric shock accidents occurs, adopt the adhesive film of said ratio also to have the effect of diffused light, printing opacity simultaneously, improve Luminescence Uniformity and the light transmittance of whole LED daylight lamp.
It should be noted that because the lamp plate in the present embodiment is flexible base board, therefore also can not adhesive film be set.
In order to improve the light efficiency of LED daylight lamp further, the present embodiment also improves LED daylight lamp, respectively for fluorescent tube and light source from two aspects.
(1) to the improvement that fluorescent tube is done
With reference to Figure 12, except the lamp plate 2 (or flexible base board) being close to fluorescent tube 1 also comprises diffusion layer 13 in the fluorescent tube 1 of the present embodiment, the light that light source 202 produces is by passing fluorescent tube 1 after diffusion layer 13.
The light that diffusion layer 13 pairs of light sources 202 send plays the effect of diffusion, therefore, as long as pass fluorescent tube 1 again after light therethrough diffusion layer 13 can be made, the layout of diffusion layer 13 can have various ways, such as: diffusion layer 13 can apply or be covered on the inner peripheral surface of fluorescent tube 1, or coating or the diffusion coating (not shown) be covered on light source 202 surface, or cover (or covering) diffusion barrier sheet outside light source 202 as an outer cover.
As Figure 12, diffusion layer 13 is diffusion barrier sheet, and covers 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, the combination of one or more in usual PS polystyrene, PMMA polymethyl methacrylate, PET (PET), PC (Merlon) is arranged in pairs or groups diffusion particle, a kind of composite formed, can diffusion be there is when this composite of light therethrough, can revise light uniformly area source with reach optics diffusion effect finally make to distribute from the brightness uniformity of fluorescent tube.
When diffusion layer 13 is diffusion coating, its composition can comprise at least one in calcium carbonate, strontium phosphate.When the diffusion coating utilizing the suitable solution of calcium carbonate or strontium phosphate or both mix and match to be formed, will there is the effect of excellent diffusion and printing opacity (having an opportunity to reach more than 90%).In addition, also find through the creative work of tool, 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 101 of fluorescent tube, can increase the frictional force between lamp holder and fluorescent tube between diffusion coating and PUR 6, 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 allocating, the constituent of diffusion coating comprises calcium carbonate strontium phosphate (such as CMS-5000, white powder), thickener (such as thickener DV-961, milky white liquid), and ceramics activated carbon (such as ceramic active carbon SW-C, colourless liquid).Wherein, the chemistry of thickener DV-961 is called colloidal silica denaturing acrylamide resin, and its component comprises acrylic resin, silica gel and pure water; The component of ceramic active carbon SW-C comprises succinate sulfonate sodium, isopropyl alcohol and pure water, and wherein the chemical formula of succinate sulfonate sodium is:
Particularly, diffusion coating with calcium carbonate strontium phosphate for main material, collocation thickener, ceramic active carbon and deionized water, be coated on after mixing on the inner peripheral surface of glass lamp, the average thickness of coating drops between 20 ~ 30 μm, and last deionized water will vapor away, only remaining calcium carbonate, thickener and ceramic active carbon three kinds of materials.Adopt the diffusion layer 13 that this material is formed, the light transmittance of about 90% can be had.In addition, this diffusion layer 13, except the effect with diffused light, can also play the effect of electric isolution, thus makes when glass lamp breaks, and reduces the risk that user gets an electric shock; Meanwhile, this diffusion layer 13 can make light source 202 when luminescence, allows light produce diffusion, toward penetrating, thus the rear of light source 202 can be shone, namely near the side of flexible base board from all directions, avoid forming dark space in the lamp vessel 1, the illumination comfort of room for promotion.

In the present embodiment, the reflectivity of reflectance coating 12 is at least greater than 85%, and reflecting effect is better, time generally more than 90%, preferably can reach more than 95%, to obtain more preferably reflecting effect.The length that reflectance coating 12 extends along fluorescent tube 1 circumference occupies 30% ~ 50% of whole fluorescent tube 1 circumference, and that is, along the circumferential direction of fluorescent tube 1, the proportion between the circumferential lengths of reflectance coating 12 and the girth of fluorescent tube 1 inner peripheral surface is 0.3 ~ 0.5.Spy gives explanation, and the utility model is only arranged on reflectance coating 12 medium position circumferentially for light source 202, as shown in figure 12.The material of reflectance coating can be PET, and thickness is between 140 μm ~ 350 μm, and generally between 150 μm ~ 220 μm, effect is better.
In other embodiments, reflectance coating 12 also can adopt other forms to arrange, and such as, along the circumferential direction of fluorescent tube 1, reflectance coating 12 can be located at the one or both sides of light source 202, and its ratio occupying fluorescent tube 1 circumference is identical with the present embodiment.Or as Figure 13, reflectance coating 12 can not offer perforate, directly reflectance coating 12 is sticked on the inner peripheral surface of fluorescent tube 1 during assembling, and then the lamp plate 2 with light source 202 is fixed on reflectance coating 12.
In other embodiments, can reflectance coating 12 be only set, diffusion layer 13 is not set, as Figure 14.
In other embodiments, the width of flexible base board can be widened, the position widened, if the effect that can play reflectance coating function.As in the prior embodiments; can a coated circuit protecting layer outside flexible base board, circuit protecting layer can be a kind of ink material, has the function increasing reflection; the flexible base board widened is that starting point extends to circumference with light source, and the light of light source can make light more concentrated by the position widened.
In the embodiment of aforesaid Figure 12-14, on the inner peripheral surface of glass tube, all can coat diffusion coating, or part coats diffusion coating (having reflectance coating part not to be coated with), but no matter be any mode, diffusion coating preferably all will be coated onto on the outer surface of end of fluorescent tube 1, to make the gluing between lamp holder 3 and fluorescent tube 1 more firm.
(2) to the improvement that light source is done
With reference to Figure 15, it is comprise the support 202b with groove 202a that light source 202 can be improved further, and is located at the LED grain 18 in groove 202a.Be filled with fluorescent material in groove 202a, fluorescent material covers LED grain 18, to play the effect of Color Conversion.In a fluorescent tube 1, light source 202 has multiple, and multiple light source 202 is arranged into row or multiple row, and often row light source 202 is arranged along the axis (Y-direction) of fluorescent tube 1.Groove 202a in each support 202b can be one or more.
Wherein, the support 202b of at least one light source 202 has the first side wall 15 along the arrangement of fluorescent tube length direction, and along the second sidewall 16 that fluorescent tube width is arranged, the first side wall 15 is lower than the second sidewall 16.Or the support 202b of at least one light source 202 has the second sidewall 16 extended along fluorescent tube length direction, and along the first side wall 15 that fluorescent tube width extends, the first side wall 15 is lower than the second sidewall 16.The first side wall herein, the second sidewall refer to the sidewall surrounding groove 202a.
In the present embodiment, each support 202b has a groove 202a, corresponding, each support 202b has two the first side walls, 15, two the second sidewalls 16.
Wherein, two the first side walls 15 are along fluorescent tube 1 length direction (Y-direction) arrangement, and two the second sidewalls 16 are arranged along fluorescent tube 1 width (X-direction).The first side wall 15 extends along the width (X-direction) of fluorescent tube 1, and the second sidewall 16 extends along the length direction (Y-direction) of fluorescent tube 1, surrounds groove 202a by the first side wall 15 and the second sidewall 16.In other embodiments, in a row light source, allow the arrangement or the extension mode that wherein have the sidewall of the support of one or more light source to adopt other.
When user is from the side of fluorescent tube, such as, when observing fluorescent tube in X direction, the second sidewall 16 can stop that the sight line of user directly sees light source 202, to reduce the discomfort of particle.Wherein, the first side wall 15 " width along fluorescent tube 1 " extends, as long as it is substantially identical with the width of fluorescent tube 1 to meet extension trend, do not require strict parallel with the width of fluorescent tube 1, such as, the first side wall 15 can have a little differential seat angle with the width of fluorescent tube 1, or the first side wall 15 also can be the various shapes such as fold-line-shaped, arc, waveform; Second sidewall 16 " length direction along fluorescent tube 1 " extends, as long as it is substantially identical with the length direction of fluorescent tube 1 to meet extension trend, do not require strict parallel with the length direction of fluorescent tube 1, such as, second sidewall 16 can have a little differential seat angle with the length direction of fluorescent tube 1, or the second sidewall 16 also can be the various shapes such as fold-line-shaped, arc, waveform.
In the present embodiment, the first side wall 15 is lower than the second sidewall 16, light can be made easily can to cross support 202b exhale, through the line space design that density is moderate, the discomfort of particle can not be produced in the Y direction, in other embodiments, if the first side wall is not less than the second sidewall, then often between row light source 202 will arrange tightr, could reduce granular sensation, raising usefulness.
Wherein, the inner surface 15a of the first side wall 15 is domatic, and relative to the form be set to by inner surface 15a perpendicular to diapire, domatic is arranged so that light more easily passes domatic exhaling.Domaticly can comprise plane or cambered surface, adopt plane in the present embodiment, and the gradient of this plane be between 30 degree ~ 60 degree.That is, the angular range between the diapire of plane and groove 202a is between 120 degree ~ 150 degree.
In other embodiments, the gradient of plane can also between 15 degree ~ 75 degree, and that is, the angular range between the diapire of plane and groove 202a is between 105 degree ~ 165 degree.Or domatic can be the combination of plane and cambered surface.
In other embodiments, if light source 202 is multiple row, and arrange along the axial direction (Y-direction) of fluorescent tube 1, the support 202b of outermost two row light source 202 (i.e. two row light sources 202 of adjacent lamp tube tube wall) is only wanted to have two the first side walls 15 of arranging along fluorescent tube 1 length direction (Y-direction) and two second sidewalls 16 of arranging along fluorescent tube 1 width (X-direction), that is, the support 202b of outermost two row light source 202 has the first side wall 15 that the width (X-direction) along fluorescent tube 1 extends, and along the second sidewall 16 that the length direction (Y-direction) of fluorescent tube 1 extends, the support 202b orientation of other row light sources 202 between this two row light source 202 does not then limit, such as, the support 202b of middle column (the 3rd row) light source 202, each support 202b can have two the first side walls 15 of arranging along fluorescent tube 1 length direction (Y-direction) and two second sidewalls 16 of arranging along fluorescent tube 1 width (X-direction), or each support 202b can have two the first side walls 15 of arranging along fluorescent tube 1 width (X-direction) and two second sidewalls 16 of arranging along fluorescent tube 1 length direction (Y-direction), or be staggered etc., as long as when user is from the side of fluorescent tube, such as, when observing fluorescent tube in X direction, second sidewall 16 of outermost two row light source 202 medium-height trestle 202b can stop that the sight line of user directly sees light source 202, the discomfort of particle can be reduced.Identical with the present embodiment, for outermost two row light sources, allow the arrangement or the extension mode that wherein have the sidewall of the support of one or more light source to adopt other.
As can be seen here, when multiple light source 202 is arranged into the row along fluorescent tube length direction, in the support 202b of multiple light source 202, all second sidewalls 16 of the same side are positioned on same straight line along fluorescent tube width, namely the second sidewall 16 of homonymy forms the structure being similar to a face wall, to stop that light source 202 is directly seen in the realization of user.
When multiple light source 202 is arranged into the multiple row along fluorescent tube length direction, multiple row light source 202 distributes along the width of fluorescent tube, and for being positioned at along the outermost two row light sources of fluorescent tube width, in the support 202b of the multiple light sources 202 often arranged, be positioned at all second sidewalls 16 of the same side on same straight line along fluorescent tube width.This is because: when user observes fluorescent tube in the width direction from the side, as long as second sidewall 16 of outermost two row light source 202 medium-height trestle 202b can stop that user's sight line directly sees light source 202, then what just can reach reduction particle is not the object of comfort.And one of centre is arranged or several row light source 202, requirement is not done in the arrangement of its sidewall, extension mode, can be identical with outermost two row light sources 202, can adopt other arrangement modes yet.
