Specific implementation mode

To keep the purpose, technical scheme and advantage of the application clearer, below in conjunction with the application specific embodiment and Technical scheme is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the application one Section Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing Go out the every other embodiment obtained under the premise of creative work, shall fall in the protection scope of this application.

Below in conjunction with attached drawing, the technical solution that each embodiment of the application provides is described in detail.

The embodiment of the present application discloses a kind of Projecting Lamp, as shown in Figures 1 to 4, Projecting Lamp include shell 10, lampshade 11, Light source module group 12 and waterproof ventilated membrane 13.Shell 10 generally use opaque material, mainly shield, shell 10 with Lampshade 11 surrounds assembly cavity 14 jointly, and light source module group 12 is arranged in the inside of assembly cavity 14.

Light source module group 12 includes light source board 120 and luminescence unit 122, and luminescence unit 122 is arranged in the side of light source board 120 Surface, and luminous energy can be converted electrical energy into.Lampshade 11 is manufactured using translucent material, and effect is produced by making luminescence unit 122 Light can be irradiated to the external world.It under normal conditions can also be between lampshade 11 and light source module group 12 in order to improve light utilization Reflector 18 is set.

Gas-permeable channels 100 are provided on shell 10, assembly cavity 14 is connected by gas-permeable channels 100 with the external world, while waterproof Ventilated membrane 13 covers gas-permeable channels 100, that is, all gases by gas-permeable channels 100 also will all pass through assembly cavity 14, lead to Crossing this mode waterproof ventilated membrane 13 can be by the moisture barrier entered by the external world in the air inside assembly cavity 14 outside.

Due to the presence of gas-permeable channels 100, the gas inside and outside Projecting Lamp can mainly be circulated by gas-permeable channels 100, Although gas circulation, for gas-permeable channels 100, gap may also be had at the gap of shell 10 and lampshade 11 The gas circulation very little at place.This also means that the steam that can enter assembly cavity 14 from gap is seldom, gas-permeable channels 100 It is only the main thoroughfare of air and steam.Therefore, waterproof ventilated membrane 13 lives the moisture barrier in this partial air, Bian Ke great The moisture content being lowered into amplitude inside assembly cavity 14 leads to the several of charging member damage to also reduce condensation vapor Rate.

In the present embodiment, waterproof ventilated membrane 13 can be arranged in the outside of shell 10, can also be arranged in assembly cavity 14 Inside.When waterproof ventilated membrane 13 is arranged in the outside of shell 10, air can first by waterproof ventilated membrane 13, later again into Enter in gas-permeable channels 100.And when waterproof ventilated membrane 13 is arranged in the inside of assembly cavity 14, air can first pass through gas-permeable channels Then 100 pass through waterproof ventilated membrane 13 again.Two ways does not have apparent difference on effect.It is contemplated that waterproof ventilated membrane 13 Protection, preferably by waterproof ventilated membrane 13 be arranged in assembly cavity 14.

In order to adjust direction of illumination, usually can also have holder 15 and screw 16.Correspondingly, can also be arranged on the housing 10 In the screw hole 102 that screw 16 coordinates.The both ends of screw hole 102 are connected to assembly cavity 14 and the external world respectively, can on holder 15 The structures such as mounting hole 150 are arranged, and it is articulated on shell 10 by the screw-thread fit of screw 16 and screw hole 102.

For Projecting Lamp, the sizes of gas-permeable channels 100 compared to be for the structures such as screw hole 102 it is fairly small, It is easy to if being separately provided on the housing 10 by blockings such as dusts.In such a case, it is possible to consider gas-permeable channels 100 Integral structure is formed with screw hole 102.Specifically, as shown in figure 4, gas-permeable channels 100 include ventilating groove 100a, ventilating groove 100a It is opened on the inner surface of screw hole 102, in order to meet ventilative needs, one end of ventilating groove 100a extends to assembly cavity 14, thoroughly The other end of air drain 100a extends to the external world.Ventilating groove 100a in the present embodiment can be in that oblique line, curve etc. extend mode, very Extremely directly the internal thread of screw hole 102 can be used as ventilating groove 100a.However, in aforesaid way ventilating groove 100a path Longer, the gas resistance suffered in ventilating groove 100a internal circulations is larger.In a preferred approach, ventilating groove 100a can edge The axial direction for screw hole 102 is extended with form of straight lines, and the path of such ventilating groove 100a is most short, minimum to the resistance of gas.It is anti- Water ventilated membrane 13 covers one end that ventilating groove 100a extends to assembly cavity 14 at this time.

In this way, gas-permeable channels 100 just form integral structure with screw hole 102.Since Projecting Lamp when in use can be through Often rotation, therefore screw hole 102 is nearby hardly formed stable dust adhesive layer, to ensure that the unobstructed of gas-permeable channels 100.

Under normal conditions, holder 15 is understood apart from the outer surface of shell 10 very after 102 coordination hinge of screw 16 and screw hole Close even to directly fit together, if gasket is arranged, gasket also can be close to shell 10 instead of holder 15.Such case Under, one end that ventilating groove 100a is in communication with the outside is possible to be blocked by holder 15 or gasket, causes gas circulation difficult.For Such case is avoided, can also include outer rim 104 on the housing 10, outer rim 104 surrounds one that screw hole 102 be in communication with the outside End and radially extending along screw hole 102.At the same time, gas-permeable channels 100 further include epitaxial bath 100b, and epitaxial bath 100b is opened It is located in outer rim 104, one end of epitaxial bath 100b is connected to ventilating groove 100a, and the other end of epitaxial bath 100b extends to outer rim 104 edge.

In this way, will not block epitaxial bath 100b holder 15 or gasket are fitted in outer rim 104, air is still It so can enter epitaxial bath 100b by the edge of outer rim 104, and eventually enter into ventilating groove 100a.Epitaxial bath 100b can edge Radially extending for screw hole 102, can also be extended along the tangential or even helical manner of such as screw hole 102.And it compares In other manner, the mode path radially extended is most short, also minimum to the resistance of air.

Multiple gas-permeable channels 100 can be arranged in each screw hole 102 simultaneously, these gas-permeable channels 100 can be along screw Hole 102 is circumferentially arranged, such as four gas-permeable channels 100 shown in Fig. 4 are arranged in a manner of an angle of 90 degrees of interval, so as to so that gas Body dispersion circulation, reduces the entirely ineffective probability of gas-permeable channels 100.

Waterproof ventilated membrane 13 can cover gas-permeable channels 100 by way of bonding, however under the influence of environment, bonding Adhesive may aging and lose viscosity, cause waterproof ventilated membrane 13 to be no longer able to closely cover gas-permeable channels 100.This When, the air in gas-permeable channels 100 is just possible to just enter the inside of assembly cavity 14 without waterproof ventilated membrane 13, to shadow The control effect of Xiangshui County's vapour.

In order to ensure that waterproof ventilated membrane 13 closely covers gas-permeable channels 100 always, bullet can be set in assembly cavity 14 Property support element 17, while fixed part 106 is provided in assembly cavity 14, fixed part 106 can be directly integrally formed with shell 10, Fixed part 106 is oppositely arranged with waterproof ventilated membrane 13, elastic supporting member for supporting optical member 17 just setting waterproof ventilated membrane 13 and fixed part 106 it Between and using the elastic force of itself waterproof ventilated membrane 13 and 10 moment of shell are compressed, ensure waterproof ventilated membrane 13 and gas-permeable channels 100 tight connection status.

Any component for having elasticity may be used in elastic supporting member for supporting optical member 17, however in view of cost and installation are difficult to journey Degree, it is preferred to use rubber block is as elastic supporting member for supporting optical member 17.Air hole 170 is opened up at the middle part of rubber block 17, when by rubber block plug When entering between waterproof ventilated membrane 13 and fixed part 106, air hole 170 can pass through waterproof ventilated membrane 13 and 100 phase of gas-permeable channels Connection, makes air smoothly circulate.

It under normal conditions, can be symmetrical on the housing 10 in order to make the rotation that can stablize between holder 15 and shell 10 Two screw holes 102 are set, the one end with 16 screw-thread fit of screw and articulated stand 15 respectively of each screw hole 102.? That is can the both ends of holder 15 be respectively articulated with symmetrical position on the housing 10, thus energy simultaneously by this structure The enough stability promoted when rotating.In two screw holes 102, it is only necessary to setting gas-permeable channels 100 one of wherein, certainly Gas-permeable channels 100 can be all set in two screw holes 102.

In said structure, due to holder 15 simultaneously on shell 10 symmetrical two at position be hinged, holder 15 size in 102 axial direction of screw hole is typically larger than the size of shell 10 in this direction, and due to the one of screw 16 Part will also be located at side of the holder 15 far from shell 10, therefore the outer profile of 15 entirety of screw 16 and holder is in screw hole 102 Size in axial direction can bigger.Such structure causes Projecting Lamp to be needed in packed and transported in order to adapt to screw 16 and holder 15, then Package size can integrally be increased, to cause the waste in space and cost.

In the present embodiment in order to improve the above problem, design, as shown in Figures 2 and 3, shell are optimized to shell 10 Body 10 includes the first part 10a being connected with each other and second part 10b, and assembly cavity 14 includes the light source module group assembly section of one 14a and holder are socketed area 14b.Wherein, the thickness at each position of shell 10 itself is almost the same, that is to say, that assembly cavity 14 with Shell 10 is substantially profile-followed.And light source module group assembly section 14a is surrounded by first part 10a, light source module group 12 is set to light In the 14a of source module assembly section.Holder socket area 14b is then surrounded by second part 10b, and two screw holes 102 are symmetricly set on the The both sides of two part 10b.Holder 15 has just been set in the periphery of second part 10b by screw 16 in this way.

And in the present embodiment, the size of the outer profile of second part 10b in the axial direction of screw hole 102 is less than first Divide size of the outer profile of 10a in the axial direction of screw hole 102, that is to say, that the size of second part 10b is less than first part The size of 10a.Size of the outer profile in the axial direction of screw hole 102 of first part 10a, which will also meet, simultaneously is not less than and shell Size of the outer profile of screw 16 and holder 15 after the assembly of body 10 in the axial direction of screw hole 102.Projecting Lamp is in screw in this way Size maximum in the axial direction in hole 102 is just defined by first part 10a, therefore can reduce Package size, saves space And cost.Meanwhile smaller holder 15 can also have higher structural strength.

Light source module group 12, which will emit beam, also needs to the support of electric energy, therefore Projecting Lamp will also include power cord 19, in shell Power hole 108 is provided on the second part 10b of body 10, power hole 108 is connected with holder socket area 14b, and power cord 19 is just Power hole 108 and holder socket area 14b can be passed through by the external world and are electrically connected with light source board 120.Air is by power supply in order to prevent Hole 108 largely enters, and the waterproof sealing structures such as waterproof screw 20, sealing-plug 21 can be arranged in power hole 108, these are Conventional components, details are not described herein.
