Description

A flameproof explosion-proof lamp Technical Field

[0001] The present invention relates to the technical field of explosion-proof lamps, and in particular to an explosion-proof lamp. Background Art

[0002] LED lamps will inevitably generate sparks and arcs during operation. These sparks and arcs leak from the interface of the wires to the outside of the lamp housing and easily cause explosions of external flammable gases and dust. This is especially true when used in some clean rooms. A clean room is an independent space with a specific environment where the indoor temperature, cleanliness, lighting, static electricity, etc. are controllable, and requires LED explosion-proof lamps with good explosion-proof effects. Technical issues

[0003] There are two main types of LED explosion-proof lamps. The first type is a cylindrical explosion-proof lamp, such as the Chinese utility model patent application number CN201020565300.1. The characteristic of this type of explosion-proof lamp is that the glass cover is a cylindrical structure. Its advantage is that the internal light-emitting components and power supply are easy to replace. However, its disadvantage is that the cylindrical structure of the glass cover makes it difficult to increase the thickness of the glass cover.

[0004] The second method is to use a long strip LED explosion-proof lamp, such as the Chinese utility model patents with patent application numbers CN201620819056.4 and CN201220251424.1. The advantage of this method is that since the glass cover is a flat structure, the thickness of the glass cover can be easily increased. The disadvantage is that the internal light-emitting components and power supply cannot be replaced separately, and the entire long strip LED explosion-proof lamp can only be replaced.

[0005] In addition, regarding the second type of long strip LED explosion-proof lamp, even if the light-emitting component and the power supply can be replaced, it is difficult to ensure that the power supply can be effectively supplied. Solution

[0058] Type here the best mode description paragraph of the invention. Modes for Carrying Out the Invention

[0059] The present invention is further described with reference to the following examples.

[0060] As can be seen from Figures 1 to 24, the flameproof and explosion-proof lamp described in this embodiment includes an outer profile; wherein the shell 1 of the outer profile is a long strip structure, which can be formed by drawing an entire strip of aluminum profile, which is convenient for production and manufacturing; one end of the outer profile is provided with an electrical plug 2; the other end of the outer profile is detachably connected to a fixed plug 3; the bottom of the outer profile is provided with an outer lampshade 11; a placement cavity 12 is formed between the outer profile and the outer lampshade 11; wherein the placement cavity 12 between the outer profile and the outer lampshade 11 cooperates with the electrical plug 2 and the fixed plug 3 to form a sealed space to prevent air from entering the enclosed space, thereby playing a role of flameproof and explosion-proof; a photoelectric module is detachably provided in the placement cavity 12;

[0061] The photoelectric module includes an inner profile 4; the outer wall of the inner profile 4 is in close contact with the inner wall of the outer profile shell 1, and the inner profile 4 is also a long strip structure, which can be formed by drawing the entire aluminum profile, which is convenient for production and manufacturing; since the outer profile shell 1 and the inner profile 4 are both integrally formed structures, the sealing performance of the outer profile and the sealing performance of the inner profile 4 can be effectively guaranteed; thereby ensuring the explosion-proof performance of the explosion-proof lamp.

[0062] A first inner plug 51 is provided at one end of the inner profile 4; a second inner plug 52 is provided at the other end of the inner profile 4; an inner lampshade 41 is provided at the bottom of the inner profile 4; a light-emitting element 421 and a driving power supply 431 are provided between the inner profile 4 and the inner lampshade 41;

[0063] The power plug 2 is provided with a first connector 21 ; the first inner plug 51 is provided with a second connector 511 that matches the first connector 21 ; the second connector 511 is electrically connected to the driving power source 431 .

[0064] Specifically, the explosion-proof lamp described in this embodiment integrates the light-emitting component 421 and the driving power supply 431 in the photoelectric module, and the photoelectric module is detachably connected to the placement cavity 12. When the light-emitting component 421 needs to be replaced, the fixed plug 3 is removed from the other end of the outer profile. It is only necessary to pull out the entire photoelectric module in the placement cavity 12 from the end of the outer profile, and push the new photoelectric module into the placement cavity 12, so that the second connector 511 of the first inner plug 51 is tightly plugged with the first connector 21 of the power plug 2 and then the fixed plug 3 is locked, thereby completing the replacement of the light-emitting component 421. The operation is simple and convenient, and the light-emitting component 421 of the explosion-proof lamp can be directly replaced.

[0065] In addition, since the outer profile is large in size and uses more raw materials, this embodiment integrates the light-emitting component 421 and the driving power supply 431 into the photoelectric module. When the user needs to replace them, he only needs to replace the photoelectric module, without having to replace the more expensive outer profile, which greatly saves costs. Compared with the traditional replacement of the entire explosion-proof lamp, this embodiment does not require the outer profile to be disassembled, and only the photoelectric module needs to be taken out and pushed in, which further saves installation costs.

[0066] The explosion-proof lamp described in this embodiment is an explosion-proof lamp, in which the inner profile 4 is provided with a power cavity 43; a light-emitting cavity 42 is formed between the inner profile 4 and the inner lampshade 41; the driving power supply 431 is provided in the power cavity 43; the light-emitting component 421 is provided in the light-emitting cavity 42; specifically, this embodiment divides the space between the inner profile 4 and the inner lampshade 41 into independent light-emitting cavities 42 and power cavities 43, thereby facilitating the wiring of the driving power supply 431 and the second connector 511, and making the structure of the optoelectronic module more compact and reasonable.

[0067] The power cavity 43 is filled with a sealant; the sealant is polyurethane; the sealant is not shown in the figure. Specifically, in this embodiment, the power cavity 43 is filled with polyurethane so that the entire power cavity 43 is filled with polyurethane. Since gas needs to be filled into the explosion-proof lamp when performing an explosion-proof test on the explosion-proof lamp, in this embodiment, the power cavity 43 is sealed so that gas cannot enter the power cavity 43. Most of the gas is filled into the light-emitting cavity 42. Since the optoelectronic module is divided into the power cavity 43 and the light-emitting cavity 42, the volume and space size of the light-emitting cavity 42 are reduced, thereby making the explosion-proof level of the explosion-proof lamp of this embodiment higher.

[0068] The inner profile 4 is provided with a partition 44 between the light-emitting cavity 42 and the power cavity 43; the light-emitting cavity 42 is provided at the bottom of the partition 44; the power cavity 43 is provided at the top of the partition 44; specifically, through the above arrangement, the power cavity 43 and the driving power supply 431 are provided at the top of the entire explosion-proof lamp, which can reduce the volume of the light-emitting cavity 42 without affecting the normal downward light emission of the light-emitting component 421.

[0069] The middle portion of the partition 44 is recessed toward the power cavity 43 to form a clearance groove 441. The light-emitting element 421 is disposed in the clearance groove 441. Specifically, this arrangement facilitates securing the light-emitting element 421 and allows the light-emitting element 421 to be embedded within the partition 44, making the structure more stable and reliable.

[0070] The explosion-proof lamp described in this embodiment is an explosion-proof lamp, in which the outer lampshade 11 is explosion-proof glass; the outer lampshade 11 is a long flat plate structure; specifically, this embodiment facilitates increasing the thickness of the explosion-proof glass compared to circular and curved explosion-proof glass, thereby improving the explosion-proof performance of the explosion-proof lamp.

[0071] The inner lampshade 41 is a diffusion cover; the inner lampshade 41 is an elongated structure as a whole; the cross-sectional shape of the inner lampshade 41 is an arc shape; specifically, by providing a diffusion cover, the diffusion effect of light can be enhanced, and the arc-shaped structure enables the diffusion cover to have a better diffusion effect, so that the light of the light-emitting component 421 can enter the outer lampshade 11 at more angles, thereby improving the overall light intensity of the explosion-proof lamp.

[0072] The light-emitting element 421 is a light-emitting light bar, and the light-emitting light bar is provided with light-emitting LEDs.

[0073] The sidewall of the outer profile is provided with an outer convex curved surface 14 and an inner concave curved surface 15; the inner concave curved surface 15 is located at the top of the outer convex curved surface 14; the inner lampshade 41 is located between the outer convex curved surface 14 and the inner concave curved surface 15. Specifically, this embodiment, through the above arrangement, can further reduce the space of the light-emitting cavity 42, thereby effectively ensuring the explosion-proof effect of the explosion-proof lamp. In addition, the provision of the inner concave curved surface 15 and the outer convex curved surface 14 facilitates the light emitted by the light-emitting element 421 to be refracted multiple times from the outer convex curved surface 14 and the inner concave curved surface 15 before being reflected back to the outer lampshade 11, thereby improving the luminous intensity of the explosion-proof lamp.

[0074] The explosion-proof and explosion-proof lamp described in this embodiment has the following features: the first connector 21 is fixed to the power plug 2; the second connector 511 is fixed to the first inner plug 51; the fixed plug 3 is provided with a positioning plate 31; after the fixed plug 3 is fixed to the outer profile, the positioning plate 31 abuts against the second inner plug 52; specifically, through the above-mentioned arrangement, when in use, the power plug 2 is first fixed to the outside world, and the mains is connected through the wire 26 of the power plug 2, thereby supplying power to the first connector 21; at the same time, the outer profile is fixed to the power plug 2, and the first end cover 61 and the second end cover 62 of the outer profile are both fixed to the outside world; when it is necessary to replace the optoelectronic module in the placement cavity 12, the fixed plug 3 and the second end cover 62 of the outer profile are first disassembled, thereby opening the placement cavity 12, and the user can directly replace the placement cavity The photoelectric module in 12 is pulled out from the first window 64 of the second end cover 62; then the new photoelectric module is inserted into the placement cavity 12 through the first window 64 of the second end cover 62. When inserting, first insert the first inner plug 51 into the placement cavity 12 until the second connector 511 of the first inner plug 51 passes through the first window 64 of the first end cover 61 and the second window 23 of the power plug 2 and is tightly plugged with the first connector 21 of the power plug 2. At this time, the entire photoelectric module is inserted into the placement cavity 12, and then the fixed plug 3 and the second end cover 62 are locked again. After the fixed plug 3 and the second end cover 62 are locked, the positioning plate 31 at the third window 32 of the fixed plug 3 is pressed against the second inner plug 52, so that the front and rear positions of the photoelectric module are fixed to prevent the inner profile 4 from shaking back and forth; the user does not need to disassemble the entire explosion-proof lamp, and replacement is simple and quick.

[0075] The second inner plug 52 is provided with a pull ring 521 ; this arrangement facilitates pulling the entire optoelectronic module out of the placement cavity 12 .

[0076] The optoelectronic module also includes an emergency power supply; the emergency power supply is integrated with the driving power supply 431; specifically, this embodiment facilitates the replacement of the entire optoelectronic module by integrating the emergency power supply and the driving power supply 431 in the power cavity 43, and when the driving power supply 431 fails, the emergency power supply can power the light-emitting element 421.

[0077] The outer wall of the inner profile 4 is provided with a guide groove 45 along the length direction; the inner wall of the outer profile is provided with a guide strip 16 that cooperates with the guide groove 45. Specifically, through the above arrangement, the optoelectronic module plays a guiding role when inserted into the placement cavity 12.

[0078] The outer wall of the outer profile is provided with a plurality of first heat dissipation bars 13 along the length direction; the outer wall of the inner profile 4 is provided with second heat dissipation bars 46 along the length direction at positions corresponding to the first heat dissipation bars 13 .

[0079] Specifically, in order to ensure the heat dissipation performance, this embodiment provides a first heat dissipation bar 13 and a second heat dissipation bar 46. The distance between the second heat dissipation bar 46 and the inner wall of the outer profile is small, so that the heat of the inner profile 4 can be easily transferred to the outer profile through the air; in addition, the guide bar 16 is in direct contact with the inner profile 4, which can further enhance the heat conduction between the inner profile 4 and the outer profile.

[0080] The flameproof and explosion-proof lamp described in this embodiment includes a shell 1, a first end cover 61 provided at one end of the shell 1, and a second end cover 62 provided at the other end of the shell 1;

[0081] The first end cover 61 is connected to the electrical plug 2; the second end cover 62 is detachably connected to the fixed plug 3;

[0082] A first explosion-proof surface 63 is provided on one side of the first end cover 61 and one side of the second end cover 62. The first explosion-proof surface 63 is a planar structure. The first explosion-proof surface 63 is provided with a first window 64 communicating with the placement cavity 12.

[0083] A second flameproof surface 22 is provided on one side of the electrical plug 2 and one side of the fixed plug 3; the second flameproof surface 22 is a planar structure; the first flameproof surface 63 is fitted with the second flameproof surface 22; as a more preferred option, the shape and size of the first flameproof surface 63 are the same as those of the second flameproof surface 22, so that the appearance of the two after fitting together is neater and the sealing performance is better;

[0084] The electrical plug 2 has a housing 24 therein; the second flameproof surface 22 of the electrical plug 2 has a second window 23 in communication with the housing 24; and the first connector 21 is disposed in the housing 24. The shape and size of the second window 23 are identical to those of the first window 64, so that after the first flameproof surface 63 and the second flameproof surface 22 are attached to each other, the first window 64 and the second window 23 can communicate with each other.

[0085] Specifically, the explosion-proof lamp described in this embodiment, when the first end cover 61 is fixed to the power connection plug 2 and the second end cover 62 is fixed to the fixed plug 3, the first explosion-proof surface 63 can be completely fitted with the second explosion-proof surface 22. At this time, the explosion-proof area of ​​the explosion-proof lamp is the area of ​​the first explosion-proof surface 63 minus the area of ​​the first window 64, which greatly increases the explosion-proof area. At the same time, it also increases the difficulty of external air entering the placement cavity 12 inside the explosion-proof lamp, thereby effectively improving the explosion-proof and explosion-proof performance of the explosion-proof lamp; and the distance between the edge position of the first explosion-proof surface 63 and the edge position of the first window 64 can be formed to be as short as 9.5mm-25mm, which greatly increases the explosion-proof distance compared to traditional explosion-proof lamps. When the shape and size of the first explosion-proof surface 63 are the same as those of the second explosion-proof surface 22, the explosion-proof area of ​​the explosion-proof lamp with high explosion-proof performance is the area of ​​the first explosion-proof surface 63 minus the area of ​​the first window 64, which greatly increases the explosion-proof area and also increases the difficulty of external air entering the interior of the explosion-proof lamp, thereby effectively improving the explosion-proof and explosion-proof performance of the explosion-proof lamp.

[0086] In order to ensure the explosion-proof performance of the explosion-proof explosion-proof lamp, it is necessary to ensure that the horizontal heights of all points on the first explosion-proof surface 63 are consistent and the horizontal heights of all points on the second explosion-proof surface 22 are consistent; in addition, the shortest distance between the edge position of the first explosion-proof surface 63 and the edge position of the first window 64 is the shortest length of the explosion-proof joint surface of the explosion-proof lamp, as shown in H1 and H2 in Figure 16, and the length is 9.5mm-25mm, thereby ensuring the explosion-proof performance of the explosion-proof lamp.

[0087] The flameproof and explosion-proof lamp described in this embodiment has a fixing groove 25 on the top of the electrical plug 2 that is connected to the accommodating cavity 24; an explosion-proof connector 252 is provided on the top of the electrical plug; the fixing groove 25 is provided on the explosion-proof connector 252; and a wire 26 connected to the first connector 21 is also included.

[0089] A first through-hole 271 is provided between the accommodating cavity 24 and the fixing groove 25; a second through-hole 272 is provided in the middle of the sealing deformation member 251; the wire 26 is sequentially passed through the first through-hole 271 and the second through-hole 272; the first through-hole 271 and the second through-hole 272 are cocentrically arranged; specifically, when the wire 26 is installed and fixed in the fixing groove 25, the wire 26 in the accommodating cavity 24 is passed through the first through-hole 271 and the second through-hole 272 in sequence and then exits from the top of the electrical plug 2 to realize the upper exit method, which can save horizontal space, and the first through-hole 271 and the second through-hole 272 are cocentrically arranged, so that the fixing structure of the fixing groove 25 and the wire 26 is more stable.

[0090] The inner wall of the fixing groove 25 is provided with threads. Specifically, when the wire 26 is installed and fixed in the fixing groove 25, the wire 26 in the accommodating cavity 24 is sequentially passed through the first through-hole 271 and the second through-hole 272 to be led out from the top of the electrical plug 2, and then the external explosion-proof pipe is rotated downward. Under the action of the threaded connection, the sealing deformable member 251 is compressed during the descent of the explosion-proof pipe. During the compression of the sealing deformable member 251, the aperture of the second through-hole 272 gradually decreases until the second through-hole 272 clamps the wire 26, thereby achieving the function of fixing and sealing. In addition, the bottom of the sealing deformable member 251 is provided with an arc surface to facilitate the tightening of the aperture during the compression of the sealing deformable member 251.

[0092] The first window 64 is arranged in the middle of the first explosion-proof surface 63; the second window 23 and the third window 32 are respectively arranged in the middle of the second explosion-proof surface 22; through the above arrangement, it is possible to further ensure that the difficulty of external air entering the interior of the explosion-proof lamp can be ensured, thereby effectively improving the explosion-proof and explosion-proof performance of the explosion-proof lamp.

[0093] The edge of the other side of the first end cover 61 and the edge of the other side of the second end cover 62 are respectively welded to the edge of the end of the shell 1; specifically, during welding, the edge position of the first end cover 61 and the edge position of the second end cover 62 are surrounded, so that the entire circle edge of the first end cover 61 and the entire circle edge of the second end cover 62 are respectively welded to the entire circle edge of the end of the shell 1, so that the first end cover 61, the shell 1 and the second end cover 62 form an inseparable whole to ensure the sealing performance between the first end cover 61, the shell 1 and the second end cover 62.

[0094] The first end cover 61 and the second end cover 62 both include a fixing portion 651 and an explosion-proof portion 652; the shape of the fixing portion 651 matches the shape of the end of the shell 1; the first explosion-proof surface 63 is provided on the explosion-proof portion 652; the cross-sectional area of ​​the explosion-proof portion 652 is greater than the cross-sectional area of ​​the fixing portion 651; through the above arrangement, the explosion-proof area of ​​the explosion-proof lamp can be increased, thereby improving the explosion-proof and explosion-proof performance of the explosion-proof lamp.

[0095] The first explosion-proof surface 63 has grooves 631 around the first window 64. The second explosion-proof surface 22 has ridges 231 around the second window 23 and around the third window 32, which mate with the grooves 631.

[0103] Specifically, during the manufacturing process of the explosion-proof and explosion-proof lamp described in this embodiment, the outer lampshade 11 is first inserted from the end of the housing 1, so that the left and right sides of the outer lampshade 11 are placed in the first receiving groove 8. At this time, the middle part of the outer lampshade 11 is exposed in the opening 17. Then, the first end cover 61 and the second end cover 62 are respectively welded and fixed to the two ends of the housing 1, so that the front and rear ends of the outer lampshade 11 are placed in the second receiving groove 9.

[0104] After the installation is completed, a first glue pouring channel is formed between the outer lampshade 11 and the first accommodating groove 8, and a second glue pouring channel is formed between the outer lampshade 11 and the second accommodating groove 9. At this time, after the first glue pouring channel is connected with the second glue pouring channel, it is arranged around the entire periphery of the outer lampshade 11; by performing glue pouring operation in the glue pouring port 66, the sealant 95 has a certain fluidity, so that the sealant 95 fills the entire first glue pouring channel and the second glue pouring channel. After the sealant 95 dries, the four sides of the outer lampshade 11 are tightly sealed with the shell 1, the first end cover 61 and the second end cover 62 respectively, with good sealing performance, and the sealing is performed by glue pouring, which is convenient for operation.

[0112] The second glue pouring channel further includes a second upper glue pouring channel 93 and a second lower glue pouring channel 94; wherein the second upper glue pouring channel 93 is aligned with the first upper glue pouring channel 82, and the two are consistent in shape and size; the second lower glue pouring channel 94 is aligned with the first lower glue pouring channel 83, and the two are consistent in shape and size;

[0113] The second upper glue pouring channel 93 is formed by the top wall of the second accommodating groove 9 and the top walls on the left and right sides of the outer lampshade 11; the second lower glue pouring channel 94 is formed by the bottom wall of the second accommodating groove 9 and the bottom walls on the left and right sides of the lampshade; the second upper glue pouring channel 93 and the second lower glue pouring channel 94 are respectively connected to the second side glue pouring channel 92;

[0114] The second lower glue pouring channel 94 is connected to the end glue pouring channel 91; the second lower glue pouring channel 94 is arranged between the end glue pouring channel 91 and the second side glue pouring channel 92; the depth of the end glue pouring channel 91 is greater than the depth of the second lower glue pouring channel 94; specifically, through the above arrangement, when the sealant 95 flows in the second side glue pouring channel 92, it can flow to the second upper glue pouring channel 93 and the second lower glue pouring channel 94 at the same time, so that the dried sealant 95 can tightly seal the bottom and top of the left and right sides of the outer lampshade 11 with the second accommodating groove 9.
