Description
Technical field
The present invention relates to a kind of light fixture, especially relate to a kind of LED light fixture and corresponding method for packing thereof with water-proof function.
Background technology
At present, the LED light fixture with good energy-saving effect starts progressively to promote, and LED light fixture generally includes LED lamp plate, is arranged on the heat sink at the LED lamp plate back side, in order to the drain pan of mounted LED lamp plate and heat sink and be located at the printing opacity cover cap on drain pan.When LED light fixture need to be installed to humidity or fish jar etc. while having in the environment of water, need to possess corresponding classification of waterproof, at present, conventional way is that waterproof coating is set on LED lamp plate surface, in the junction of diffuser lid and bottom shell, sealing ring is set simultaneously.
For example, a kind of disclosed in Chinese patent literature " waterproof LED lamp strip ", notification number is CN202302956U, includes the some LED luminescence units that are arranged on circuit base plate, at described circuit base plate and LED luminescence unit surface coverage, have watertight composition, described watertight composition is Parylene rete.This LED lamp bar has good insulation, waterproof and dustproof, corrosion resistance.Yet sealing method can only play basic moisture-proof role to LED lamp plate, cannot carry out whole sealing to housing, so its classification of waterproof is not high.
Another kind of disclosed in Chinese patent literature " the LED light fixture of waterproof ", publication No. is CN102086983A, and it comprises a radiator, and a LED lighting module is to be 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 this LED lighting module cover is established; And one electrical connector be fixed on this radiator, and be electrically connected to this LED lighting module.By the setting of this connecting ring, make this diffuser be able to effectively airtight this LED lighting module, to prevent that light fixture from infiltrating aqueous vapor.Because need to making by the structure of trip bolt one class diffuser conventionally, this type of encapsulating method compresses the connecting ring (being sealing ring) for sealing, therefore cause the complexity of its structure, particularly, between its two adjacent screws, there is certain interval, therefore, laminate pressure between housing and connecting ring is inhomogeneous, and between screw, the pressure at interval is less, thereby is difficult to adapt to the occasion that has higher level to require to waterproof.
Certainly, also there is people by applying fluid sealant to reach the effect of sealing between drain pan and printing opacity cover cap, yet, there are the following problems on the LED of existing strip light fixture, to adopt sealant sealing: first, due to the edge coating fluid sealant that need to close at diffuser lid and bottom shell joint, and printing opacity cover cap Zai edge is screwed on drain pan, the length that therefore need to apply fluid sealant is long, be difficult to guarantee that the coating of fluid sealant on whole sealing strips puts in place and uniformity, thereby 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, adopt after 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 being subject to the effect of above-mentioned escaping gas and the effect of screw, thereby occurs cracking.At present, one of countermeasure that people take is by changing repeatedly the different trades mark and different types of fluid sealant, observes its cracking situation, to select suitable fluid sealant after encapsulation a period of time again.Although by selecting suitable fluid sealant can improve to a certain extent the problem of Cracking of printing opacity cover cap, but cannot fundamentally effectively address this problem.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, 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 plate 2 and heat sink 3 in housing, on LED lamp plate, can apply electronic seal glue, housing wherein comprises that the printing opacity body 11 of tubular of a both ends open and shutoff are at the end cap 12 at printing opacity body two ends, between end cap and printing opacity body, by fluid sealant, be fixedly connected with, printing opacity body can adopt PC plastics to make, to make it have enough intensity and higher light transmission.Printing opacity body comprises a straight diapire 111, thereby is conducive to light fixture installation location in use, and the dual-side of diapire dual-side and a major arc post jamb 112 links into an integrated entity, and this major arc post jamb is the post jamb that a major arc stretches vertically and forms.In addition, we also need arrange axial arranged card article 113 in two inner sides of major arc post jamb, the both sides of heat sink correspondingly arrange the draw-in groove 31 with card article adaptation, thereby heat sink can be inserted from one end of printing opacity body, and draw-in groove is connected on card article, thereby heat sink is fixed, and should be guaranteed that the bottom surface of heat sink and diapire fit, so as by the heat of LED lamp plate by heat sink and the outside Quick diffusing of housing.
In order to facilitate processing and manufacturing, we also can make printing opacity body cylindrical shape as shown in Figure 3, certainly, also need axial arranged card article 113 be set in the both sides of printing opacity body medial surface, correspondingly, 3 of heat sinks are semi-cylindrical shaped, it comprises for the straight assembly wall 32 of mounted LED lamp plate and the heat radiation wall 33 of semicircle column type, as hereinbefore, heat sink can insert from one end of printing opacity body, the heat radiation wall of heat sink and the laminating of the inwall of printing opacity body, the assembly wall of heat sink is by the card article screens of both sides, thereby heat sink is fixed, and be also connected with reinforcement sheet 34 between the assembly wall of heat sink and heat radiation wall, both be conducive to improve the intensity of heat sink, the heat being 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 printing opacity body two ends, correspondingly, screw-shaped raised line 121 is set on the madial wall of end cap, thereby end cap can be screwed on printing opacity body, and raised line now fits in groove, between raised line and groove, be perfused with fluid sealant to realize sealing.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, thereby 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 to be positioned at end cap the end of printing opacity body reliably, just can guarantee all there is uniform gap between raised line and all surface of groove, for this reason, we can arrange respectively a dog screw 35 in the axial location of heat sink two ends correspondence printing opacity body, a positioning stud 122 is set in the bottom surface of end cap, and pitch and the rotation direction of dog screw and raised line are identical simultaneously, when end cap screws on printing opacity body, dog screw forms and is threaded with positioning stud.It should be noted that, the external diameter of dog screw should be large as far as possible, like this, between dog screw and positioning stud, can form comparatively closely and be threaded, make end cap printing opacity body axially and footpath upwards all located reliably.
As Figure 1 and Figure 4, in order to ensure the perfusion of fluid sealant, put in place, we can arrange at the edge of opening of end cap a sealing ring 4, and sealing ring has an annular slot 41, thereby its cross section is taken the shape of the letter U, and the edge of opening of end cap is connected in annular slot.In addition, the outer diameter that we can make printing opacity body be provided with the end of screw-like groove is less than the outer diameter of printing opacity body mid portion, thereby formation ladder, and establish between the outer wall of reeded end and the outer wall of mid portion with sealing cone 115 transition at printing opacity body, like this, when end cap screws in printing opacity 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 matching with sealing cone, thereby 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 near opening part at the sidewall of end cap, and like this, when we are during from fill orifice perfusion fluid sealant, fluid sealant is subject to not stopping of sealing ring and can overflows outward, thereby 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 perfusion fluid sealant, seal can first not be set in air-vent, like this, when having poured into the fluid sealant of housing one end and having started to pour into the fluid sealant of the other end, can avoid not occurring the perfusion difficulty of fluid sealant and flowing backwards because housing has venthole.In addition, after the perfusion that completes fluid sealant, we can place a period of time by housing, and like this, the escaping gas being produced by fluid sealant in housing can be released by the air-vent on the end cap of two ends.Air-vent is a stepped hole, its counterbore by the rounding taper type of outer end and be arranged on counterbore bottom surface and form with the elongated hole being communicated with in housing, and seal profile and counterbore are adaptive, cavity 51 is set on the inner face of seal, thereby can increase the elasticity of seal, and when the escaping gas in housing distributes complete need to sealing air-vent by air-vent, can be in air-vent drip irrigation fluid sealant, and seal is filled in counterbore, thereby make by fluid sealant, to be fixedly connected with between seal and air-vent.Certainly, we also can be in air-vent direct drip irrigation fluid sealant and without seal, form sealing after the sealing glue solidifying in air-vent.
Finally, as shown in Figure 1, we can arrange two installing racks 6 on printing opacity body, and with glue, cohere fixing so that the installation of light fixture is fixed.
An encapsulating method for waterproof LED lamp, as previously mentioned, its housing comprises the printing opacity body of a tubular and the end cap that is set in printing opacity body two ends to the structure of waterproof LED lamp, end cap is provided with air-vent, specifically comprises the steps:
A. first at LED lamp plate external coating electronic dampproof glue, further to improve classification of waterproof, then between end cap and printing opacity body, pour into fluid sealant and place at least two days, the air-vent of the gas that fluid sealant volatilizes in solidification process on end cap progressively discharges.Certainly, under the prerequisite of the conditions permits such as production site, standing time can be extended as far as possible, to make fluid sealant be volatilized fully and discharge.In addition, we can insert a gas tube air-vent of housing one end, and by gas tube to injecting compressed air in housing, thereby the escaping gas in housing is discharged from the air-vent of the housing other end, so that the escaping gas that housing is created in housing in the put procedure after the careful sealing of perfusion is thoroughly emptying fast.Or, as shown in Figure 5, we also can insert the air-vent of housing one end by a gas tube 7, in the air-vent of the housing other end, insert a blast pipe 8, then the two ends of having poured into the housing of 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, thereby housing is shelved on the constant temperature oven at two ends, gas tube and blast pipe should pass from the sidewall of constant temperature oven respectively, like this, in housing put procedure, we can be by gas tube to injecting compressed air in housing, thereby the escaping gas in housing is discharged from the blast pipe of the housing other end.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 of splicing up and down, it consists of the lower baking oven 91 of upper opening and 92 docking of the upper baking oven of lower openings, and at one group of relative edge of opening of lower baking oven, semicircle orifice is set respectively, and corresponding edge of opening arranges respectively semicircle orifice on upper baking oven, 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 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 completely curing, air-vent can be sealed.
Because housing of the present invention is without adopting screw to connect, and the escaping gas that fluid sealant produces can be released by air-vent, thereby can effectively solve the problem of Cracking of housing.It should be noted that, on the end cap of housing one side, need to arrange through wires hole, to connect the wire of power supply, can pass through wires hole, and be electrically connected to LED lamp plate, wire and through wires hole junction can arrange corresponding sealing sheath, and pay close attention to sealant sealing, above-mentioned steps can be used as one independently operation before seal casinghousing, complete so that the escaping gas of fluid sealant can distribute fully.
