Fig. 2 is that the breathing equipment of large-power lamp is arranged on STRUCTURE DECOMPOSITION schematic diagram on the light fixture in the embodiment of the invention;
Fig. 3 is the local enlarged diagram of Fig. 2.
The specific embodiment
As shown in Figure 1 be the external structure schematic diagram of the breathing equipment of a kind of large-power lamp of the present invention.The breathing equipment of large-power lamp of the present invention is installed on the lamp casing 400, and preferred embodiment is arranged on the evagination circular arc place, back of lamp casing 400 for this breathing equipment.The pressing plate 100 of breathing equipment is fixed on the lamp casing 400, pressing plate 100 with other each parts of breathing equipment cover, be fixed on pressing plate 100 below.See hereinafter further specifying Fig. 2 and Fig. 3 for details.
Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of the breathing equipment of a kind of large-power lamp of the present invention, and Fig. 3 is the local enlarged diagram of Fig. 2.Referring to figs. 2 and 3, breathing equipment of the present invention comprises the through hole 420 that is arranged on the lamp casing 400, be arranged on the waterwall that has breach 411 410 around the through hole 420, the permission gas of blocking through hole 420 by but the intransitable breathable barrier thing 300 of dust also comprises the seal cover 200 that is sealed on the waterwall 410.Seal cover 200 is fixed on waterwall 410 tops by a pressing plate 100.Pressing plate 100 covers seal cover 200 tops, offers corresponding hole in the both sides of pressing plate 100, seal cover 200, is provided with screw hole column 430 in the corresponding position of lamp casing 400, by screw pressing plate 100, seal cover 200 is fixed on the lamp casing 400.Through hole 420 is so that be interlinked to the outside in the lamp casing 400.It is circular that waterwall 410 is in the present embodiment, around through hole 420, to avoid rainwater to enter through hole or to soak into breathable barrier thing 300.Breach 411 on the waterwall 410 can be so that breathable barrier thing 300 communicates with outside air, so that lamp casing 400 inside and outside air pressure can be balanced by the permeation functions of breathable barrier thing 300.
When in the lamp casing 400 owing to work long hours temperature raise, during pressure rises, the higher air of pressure in the light fixture will overflow in lamp casing 400 by breathable barrier thing 300, and the air pressure in the lamp casing 400 just gradually equates with lamp casing 400 air pressure outward.When light fixture quits work, lamp casing 400 interior temperature reduce, when the air pressure in the lamp casing 400 is low, the air of lamp casing 400 outsides will be under atmospheric effect, enter lamp casing 400 from breathable barrier thing 300, the air pressure in the lamp casing 400 just gradually equates with lamp casing 400 air pressure outward.What this had just reached the light fixture breathing equipment plays the technique effect of balanced action to the lamp casing inner and outer air pressure.
Above-mentioned breathable barrier thing 300 can be selected metallic particles agglomerate or sponge or fiber block or the inner wrappage that active carbon is arranged when implementing, obviously, all can be used for enforcement of the present invention as long as can play the barrier of ventilation dustproof effect.In addition, for the barriering effect to dust that makes breathable barrier thing 300 better, breathable barrier thing 300 place waterwall 410 centers and through hole 420 over against and prop up through hole 420, and the height of breathable barrier thing 300 preferably is not higher than the top of waterwall 410, breathable barrier thing 300 is provided with for the lug boss 301 that embeds in the through hole 420, makes breathable barrier thing 300 seal more closely through hole 420.
In a preferred embodiment of the invention, seal cover 200 is rubber gasket, closely is sealed on the top of waterwall 410, plays to prevent that the top current from leaking into the effect of breathable barrier thing 300.
In a preferred embodiment of the invention, the both sides of pressing plate 100 are provided be used to the kink 110 that blocks waterwall 410 and offset with lamp casing 400, kink 110 actual and pressing plate 100 integrated formations, the extension perpendicular with the main body of pressing plate 100, the kink 110 of both sides is trapped among waterwall 410 wherein, makes the water resistance of breathing equipment of the present invention better.The bottom surface that offsets with lamp casing 400 of the kink 110 and outer surface of lamp casing 400 is adaptive coincide like this, can make the rainwater on the lamp casing 400 be difficult for directly being washed into waterwall 410.
Among Fig. 2 and the embodiment illustrated in fig. 3, waterwall 410 has two-layer.During enforcement, also the number of plies of waterwall 410 can be increased, and on every layer of waterwall 410 breach 411 is set all, breach 411 on every layer of waterwall 410 is staggered with the breach on other layers waterwall 410, then multilayer waterwall 410 namely forms mazy waterwall, is conducive to more prevent that rain drop erosion from arriving waterwall 410 circumjacent breathable barrier things 300.
Be provided with the screw hole column 430 for fixation clip 100 on the lamp casing 400, the screw on the screw hole column 430 is used for holding the screw of fixation clip 100.Screw hole column 430 is positioned at the both sides of waterwall 410, and this screw hole column 430 is provided be used to the extension 431 that blocks the breach on the outermost layer waterwall 410.Be respectively arranged with the screw corresponding with the screw on the screw hole column 430 on pressing plate, the seal cover 200.During installation, breathable barrier thing 300 is placed in the through hole 420, seal cover 200 covers the top of waterwall 410, and make screw on the seal cover 200 and the screw on the pressing plate 100 over against, breathing equipment of the present invention can be installed on the lamp casing of large-power lamp with screw.
Structure of the present invention can realize through hole 360 ° of water resistancees that scope is interior all around, the current of any direction of this breathing equipment of process can be drained by the kink 110 on waterwall 410 and the pressing plate 100, seal cover 200 can play the top and prevent that current from leaking into the effect of breathable barrier thing 300, current and long-term breathable barrier thing 300 places that keep that this invention can withstand any one angle are not had by water logging, the long-term drying that keeps breathable barrier thing 300, breach 411 on the waterwall 410 can guarantee that outer gas stream is smooth and easy identical with lamp interior by breathable barrier thing 300, reaches the effect of air pressure balance.
Above embodiment has only expressed preferred embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention; Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention; Therefore, all equivalents and modifications of doing with claim scope of the present invention all should belong to the covering scope of claim of the present invention.
