Background technology
At present, the LED lamp with good energy-saving effect starts progressively to promote, and LED lamp generally includes LED lamp panel, is arranged on the heat sink at the LED lamp panel back side, in order to the drain pan of mounted LED lamp plate and heat sink and the printing opacity cover cap that is located on drain pan.When LED lamp need to be installed to humidity or fish jar etc. have in the environment of water time, need to possess corresponding classification of waterproof, at present, conventional way arranges waterproof coating on LED lamp panel surface, arranges sealing ring in the junction of diffuser lid and bottom shell simultaneously.
Such as, a kind of in Chinese patent literature disclosed " waterproof LED lamp strip ", notification number is CN202302956U, includes the some LED luminescence units be arranged on circuit base plate, have watertight composition at described circuit base plate and LED luminescence unit surface coverage, described watertight composition is Parylene rete.This LED lamp bar has good insulation, waterproof and dustproof, corrosion resistance.But sealing method can only play basic moisture-proof role to LED lamp panel, cannot carry out overall sealing to housing, therefore its classification of waterproof is not high.
Another kind of in Chinese patent literature disclosed " LED lamp of waterproof ", publication No. is CN102086983A, and it comprises a radiator, and a LED lighting module is fixed on this radiator; One connecting ring is surrounded on the periphery of this LED lighting module, and its end face is formed with a junction; One diffuser is fixed on the connecting portion of this connecting ring, and is established by this LED lighting module cover; And one electrical connector be fixed on this radiator, and to be electrically connected with this LED lighting module.By the setting of this connecting ring, make this diffuser be able to this LED lighting module effectively airtight, infiltrate aqueous vapor to prevent light fixture.Because this type of encapsulating method needs to make the connecting ring (i.e. sealing ring) of diffuser compression for sealing by the structure of trip bolt one class usually, therefore the complexity of its structure is caused, particularly, between its two adjacent screws, there is certain interval, therefore, laminate pressure between housing and connecting ring is uneven, and between screw, the pressure at interval is less, thus be difficult to adapt to have higher level to require to waterproof occasion.
Certainly, also someone passes through between drain pan and printing opacity cover cap, to apply fluid sealant to reach the effect of sealing, but, the LED lamp of existing strip adopts sealant sealing, and there are the following problems: first, owing to needing the edge coating fluid sealant closed at diffuser lid and bottom shell joint, and printing opacity cover cap is screwed on drain pan in edge again, therefore need the length applying fluid sealant long, be difficult to ensure that the coating of fluid sealant on whole sealing strip puts in place and uniformity, thus very easily leave the hidden danger of leaking; Secondly, existing printing opacity cover cap generally all adopts PC plastics to make, it has higher intensity and good light transmission, but, after adopting sealant sealing, the gas that fluid sealant volatilizes can fill in whole housing, and printing opacity cover cap easily brings out its internal stress afterwards in the effect of the effect and screw that are subject to above-mentioned escaping gas, thus occurs cracking.At present, one of countermeasure that people take is by changing the different trade mark and different types of fluid sealant repeatedly, after encapsulation a period of time, observe its cracking situation again, to select suitable fluid sealant.Although by the problem of Cracking selecting suitable fluid sealant can improve printing opacity cover cap to a certain extent, but cannot fundamentally effectively address this problem.
Summary of the invention

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention will be further described.
In embodiment as shown in Figure 1 and Figure 2, a kind of waterproof LED lamp, comprise housing 1, be arranged on LED lamp panel 2 in housing and heat sink 3, LED lamp panel can apply electronic seal glue, housing wherein comprises transparent body 11 and the end cap 12 of shutoff at transparent body two ends of the tubular of a both ends open, be fixedly connected with by fluid sealant between end cap with transparent body, transparent body can adopt PC plastics to make, to make it have enough intensity and higher light transmission.Transparent body comprises a straight diapire 111, thus be conducive to light fixture in use installation location, the dual-side of diapire dual-side and a major arc post jamb 112 links into an integrated entity, this major arc post jamb be a major arc stretch vertically formation post jamb.In addition, we also need arrange axial arranged card article 113 inside two of major arc post jamb, the both sides of heat sink then correspondingly arrange the draw-in groove 31 with card article adaptation, thus heat sink can be inserted from one end of transparent body, and make draw-in groove be connected on card article, thus heat sink is fixed, and should guarantee that the bottom surface of heat sink and diapire fit, so that by the heat of LED lamp panel by heat sink and the outside Quick diffusing of housing.
Conveniently processing and manufacturing, transparent body also can be made cylindrical shape as shown in Figure 3 by us, certainly, also axial arranged card article 113 need be set in the both sides of transparent body medial surface, correspondingly, heat sink 3 is in semi-cylindrical shaped, it comprises the heat radiation wall 33 of straight assembly wall 32 for mounted LED lamp plate and semicircle column type, as hereinbefore, heat sink can insert from one end of transparent body, the heat radiation wall of heat sink and the inwall laminating of transparent body, the assembly wall of heat sink is then by the card article screens of both sides, thus heat sink is fixed, and between the assembly wall and heat radiation wall of heat sink, be also connected with reinforcement sheet 34, both the intensity improving heat sink had been conducive to, the heat be conducive to again on assembly wall transmits fast to heat radiation wall.
Further, as shown in Figure 4, we also can arrange screw-shaped groove 114 at the lateral wall at columnar transparent body two ends, correspondingly, the madial wall of end cap is arranged screw-shaped raised line 121, thus end cap can be screwed in transparent body, raised line now fits in groove, is then perfused with fluid sealant to realize sealing between raised line and groove.The cross section of groove can be rectangle, and the cross section of raised line is rectangle equally, and becomes similar fitgures with the cross section of groove, thus makes to be formed with gap between raised line and groove, and certainly, the fluid sealant between raised line and groove should be poured in gap.Be understandable that, we need end end cap being reliably positioned at transparent body, just can guarantee, between raised line and all surface of groove, all there is uniform gap, for this reason, we the axial location of corresponding transparent body can arrange a dog screw 35 respectively at heat sink two ends, arrange a positioning stud 122 in the bottom surface of end cap simultaneously, and the pitch of dog screw and raised line and rotation direction identical, when end cap screws in transparent body, dog screw forms with positioning stud and is threaded.It should be noted that, the external diameter of dog screw should be large as far as possible, like this, can be formed and be threaded comparatively closely between dog screw with positioning stud, end cap is located all reliably in the axis and radial direction of transparent body.
As Figure 1 and Figure 4, the perfusion in order to ensure fluid sealant puts in place, and we can arrange a sealing ring 4 at the edge of opening of end cap, and sealing ring has an annular slot 41, thus makes its U-shaped profile, and the edge of opening of end cap is connected in annular slot.In addition, the outer diameter that we can make transparent body be provided with the end of thread-like groove is less than the outer diameter of transparent body mid portion, thus formation ladder, and establish between the outer wall of reeded end and the outer wall of mid portion with the transition of a sealing cone 115 in transparent body, like this, when end cap screws in transparent body end, the sealing ring on end cap just arrives the position of sealing cone, and the medial surface of sealing ring is just fitted with sealing cone.Be understandable that, the medial surface of sealing ring should be the taper seat matched with sealing cone, thus can utilize the effect of taper seat that sealing ring and sealing cone are fitted tightly.Further, we also need arrange a fill orifice 123 at the sidewall of end cap near opening part, and like this, when we are from fill orifice perfusion fluid sealant, the stop that fluid sealant is subject to sealing ring can not be overflowed outward, thus can guarantee that the perfusion of fluid sealant puts in place.Certainly, after the careful sealing of perfusion, we can fill in a flexible stopper in fill orifice, to avoid the refluence of fluid sealant.
Further, we also need arrange air-vent 124 on the end face of end cap, seal 5 is set in air-vent, when pouring into fluid sealant, seal can first not be set in air-vent, like this, when having poured into the fluid sealant of shell one end and having started the fluid sealant pouring into the other end, the perfusion difficulty and the refluence that occur fluid sealant because housing does not have venthole can be avoided.In addition, after the perfusion completing fluid sealant, housing can be placed a period of time by us, and like this, the escaping gas produced by fluid sealant in housing is released by the air-vent on the end cap of two ends.Air-vent is a stepped hole, its by the rounding taper type of outer end counterbore be arranged on counterbore bottom surface and form with the elongated hole be communicated with in housing, and seal profile and counterbore adaptation, the inner face of seal is arranged cavity 51, thus the elasticity of seal can be increased, and when the escaping gas in housing by air-vent distribute complete need to seal air-vent time, can in air-vent drip irrigation fluid sealant, and seal is filled in counterbore, thus make to be fixedly connected with by fluid sealant between seal and air-vent.Certainly, we also can in air-vent direct drip irrigation fluid sealant and without seal, when forming sealing after the sealing glue solidifying in air-vent.
Finally, as shown in Figure 1, we can arrange two installing racks 6 in transparent body, and blend compounds water coheres fixing, so that the installation of light fixture is fixed.
An encapsulating method for waterproof LED lamp, as previously mentioned, its housing comprises the transparent body of a tubular and is set in the end cap at transparent body two ends the structure of waterproof LED lamp, and end cap is provided with air-vent, specifically comprises the steps:
A. first at LED lamp panel external coating electronic dampproof glue, to improve classification of waterproof further, then between end cap and transparent body, pour into fluid sealant and place at least two days, the air-vent of gas on end cap that fluid sealant is volatilized in the curing process progressively discharges.Certainly, standing time can be extended under the prerequisite of the conditions permits such as production site, to make fluid sealant be volatilized fully and discharge as far as possible.In addition, a gas tube can be inserted the air-vent of shell one end by us, and by gas tube to injecting compressed air in housing, thus the air-vent of the escaping gas in housing from the housing other end is discharged, so that thoroughly emptying fast by producing escaping gas in housing in the put procedure of housing after the careful sealing of perfusion.Or, as shown in Figure 5, a gas tube 7 also can be inserted the air-vent of shell one end by us, a blast pipe 8 is then inserted in the air-vent of the housing other end, then the two ends of the housing pouring into fluid sealant are heated with a constant temperature oven 9 respectively, this constant temperature oven sidewall arranges through hole, the end cap of housing stretches in constant temperature oven through through hole, thus make housing be shelved on the constant temperature oven at two ends, gas tube and blast pipe then should pass from the sidewall of constant temperature oven respectively, like this, in housing put procedure, we by gas tube to injecting compressed air in housing, thus the blast pipe of the escaping gas in housing from the housing other end is discharged.For the ease of the processing of constant temperature oven and the placement of housing, constant temperature oven can be made into the cube structure spliced up and down, it is docked by the lower baking oven 91 of upper opening and the upper baking oven 92 of lower openings and forms, and the edge of opening relative in one group, lower baking oven arranges semicircle orifice respectively, and edge of opening corresponding on upper baking oven arranges semicircle orifice respectively, like this, as shown in Figure 6, the shell end of having poured into fluid sealant can first be shelved in the semicircle orifice of lower baking oven one lateral edges, gas tube or blast pipe are then shelved in the semicircle orifice of a relative lateral edges, when upper and lower baking oven is docking integrally, the semicircle orifice of upper and lower baking oven splices conglobate through hole, make end and the gas tube of housing, blast pipe screens is in through hole,
B. drip irrigation fluid sealant in air-vent, and with a seal, air-vent is sealed, wait the fluid sealant in air-vent to solidify completely, air-vent can be sealed.
Because housing of the present invention connects without the need to adopting screw, and the escaping gas that fluid sealant produces is released by air-vent, thus effectively can solve the problem of Cracking of housing.It should be noted that, the end cap of housing side needs to arrange through wires hole, so that the wire connecting power supply can pass through wires hole, and be electrically connected with LED lamp panel, wire and through wires hole junction then can arrange corresponding sealing sheath, and pay close attention to sealant sealing, above-mentioned steps can be used as one independently operation complete before seal casinghousing, so that the escaping gas of fluid sealant can distribute fully.
