The housing 100 may be made of aluminum alloy, or may be made of aluminum alloy and plastic. The casing 100 is used for providing a mounting support function, and is used for collectively mounting the heat dissipation plate 200, the two limit blocks 300, the plurality of heat dissipation bodies 400 and the micro fan 500; meanwhile, the housing 100 is also used to be mounted externally to implement a lighting function in combination with the LED lamp panel. The heat dissipation plate 200 may be made of an aluminum alloy material, or may be made of an aluminum alloy and plastic. The heat dissipation plate 200 is used for installing an LED lamp panel, namely a PCB (printed Circuit Board) integrated with LED lamp beads, so that heat generated by the LED lamp panel during working can be conducted to the outside through the heat dissipation plate 200. The two limiting blocks 300 can be made of aluminum alloy materials or can be formed by compounding aluminum alloy and plastic. The two stoppers 300 are mainly used for cooperating with the heat sink 200 to fix the heat sink 200 on the housing 100. The heat sink 400 is made of an aluminum alloy material, and absorbs and conducts heat conducted from the heat sink 200. The micro fan 500 serves to blow air toward the case 100 to dissipate heat accumulated in the heat radiator 400. The wiring board 600 is made of aluminum alloy material, or aluminum alloy and plastic. The wiring board 600 is used for connecting an external power supply and electrically connecting with the LED lamp panel 30, and is used for matching with the heat sink 200 to fix the heat sink 200 on the housing 100.

The housing 100 is opened with a heat dissipating through-hole 110. For example, the heat dissipating ports 110 have a rectangular cross-section, and for example, the heat dissipating ports 110 have a circular cross-section, which facilitates mold-open production. The housing 100 further has a limiting groove 120 formed on two opposite sides of the heat dissipating through-hole 110. For example, the restraint slot 120 has a rectangular cross-section. The limiting groove 120 is communicated with the heat dissipation port 110. In other words, the housing 100 is formed with the limiting groove 120 and the heat dissipating through-hole 110 communicating with each other, and the limiting groove 120 and the heat dissipating through-hole 110 communicate with each other as a whole. In this embodiment, the length of the limiting groove 120 is smaller than the length of the heat dissipating port 110, so that the limiting groove 120 with a shorter length is disposed outside the heat dissipating port 110, so as to facilitate the installation of the two limiting blocks 300 and further fix the heat dissipating plate 200.

For example, the case 100 has a rectangular parallelepiped structure; as another example, the housing 100 is a cube; as another example, the housing 100 has a triangular prism structure. Preferably, the housing 100 has a rectangular parallelepiped structure. The housing 100 has a receiving groove 130 and a heat dissipating channel 140, the receiving groove 130 is communicated with the heat dissipating port 110 through the heat dissipating channel 140, so that the receiving groove 130, the heat dissipating channel 140 and the heat dissipating port 110 are communicated with each other, so that air can circulate in the receiving groove 130, the heat dissipating channel 140 and the heat dissipating port 110, and the heat collected in the heat dissipating port 110 can be taken away in time.

For example, the housing 100 is opened with a screw hole 150, and the housing 100 is mounted on the ring-shaped casing 1 through the screw hole 150. The threaded hole 150 corresponds to the positioning column 13, the positioning column 13 is inserted into the threaded hole 150, and the limiting plate 14 abuts against the surface of the housing to mount the housing on the mounting position 12. For example, the limiting plate 14 is rotatably disposed at the end of the positioning column 13, for example, the limiting plate 14 is located at the end surface of the positioning column 13 when the limiting plate 14 is at the first rotating position, and the limiting plate 14 protrudes out of the end side of the positioning column 13 when the limiting plate is at the second rotating position, so that after the positioning column 13 is inserted into the threaded hole 150, the limiting plate 14 is rotated to clamp the casing 100, and the casing is mounted on the mounting position 12. It can be understood, limiting plate 14 rotates and sets up in terminal of reference column 13 can adopt spacing mode of rotating the connection, for example, circular recess has been seted up to reference column 13's end, limiting plate 14's middle part is provided with cylindrical protrusion, cylindrical protrusion inserts in the circular recess, and, the bottom of circular recess is the spherical structure recess, cylindrical protruding end is the spherical structure solid, cylindrical protrusion inserts back limiting plate 14 and reference column 13 in the circular recess like this and forms relatively fixed relation of being connected, limiting plate 14 is difficult for droing from reference column 13 promptly, and limiting plate 14 is rotatable relative reference column 13.

For example, the number of the screw holes 150 is two, and the two screw holes 150 are respectively provided at both sides of the housing 100. In this embodiment, two threaded holes 150 are respectively disposed in the regions of the opposite corners of the two sides of the housing 100, correspondingly, two positioning columns 13 are disposed in each mounting position 12, the two positioning columns 13 are respectively disposed in the regions of the opposite corners of the two sides of the mounting position 12, and each positioning column 13 corresponds to one threaded hole 150. It can be understood that, after the casing 100 is installed on the annular housing 1 through the threaded hole 150, a plurality of LED lamps are installed on the annular housing 1 and the light emitting colors of the LED lamps are set, so that a colorful combined lamp can be formed and the LED lamps are installed on the annular housing 1 conveniently and quickly, and the efficiency is high.

For example, the heat sink 200 has a rectangular parallelepiped structure. The heat dissipation plate 200 covers the heat dissipation opening 110. For example, the heat sink 200 is located at an opening side of the heat dissipating port 110 and covers the heat dissipating port 110. For example, the heat dissipation plate 200 and the heat dissipation port 110 are engaged with each other. That is to say, the length and width of the heat dissipation plate 200 are equal to the length and width of the heat dissipation through holes 110, so that the heat dissipation plate 200 completely covers the heat dissipation through holes 110, and after the heat dissipation plate 200 completely covers the heat dissipation through holes 110, the surface of the heat dissipation plate 200 is flush with the surface where the edges of the heat dissipation through holes 110 are located, thereby making the whole structure more compact, reasonable and orderly. In this embodiment, the heat dissipation plate 200 is a plate-shaped structure made of an aluminum alloy material. For example, the heat sink 200 is provided with the fixing block 210, and for example, the heat sink 200 is integrally formed with the fixing block 210 by casting aluminum. The heat dissipation plate 200 is provided with a conductive through hole 220 adjacent to the fixing block 210, and the fixing block 210 and the conductive through hole 220 are commonly used for connecting the wiring board 600, so that the heat dissipation plate 200 and the wiring board 600 are matched and fixedly connected with each other. For example, the heat dissipation plate and the heat dissipation port are engaged with each other.

For example, the stopper 300 has a rectangular parallelepiped structure. For example, the heat dissipation plate 200 is integrally formed with the two stoppers 300. The two stoppers 300 are respectively disposed on two sides of the heat dissipation plate 200, and each stopper 300 is correspondingly embedded in one of the stopper grooves 120. The limiting block 300 is engaged with the limiting groove 120. In order to quickly mount and dismount the heat dissipation plate 200, for example, the end of the limiting groove 120 is provided with a clamping protrusion 121, the end of the limiting block 300 is correspondingly provided with a clamping groove 310, and the clamping protrusion 121 is clamped in the clamping groove 310. For example, both ends of spacing groove 120 are provided with the block arch 121 respectively, the both ends of stopper 300 correspond respectively and have been seted up block recess 310, can utilize block arch 121 and block recess 310's block to be connected like this, can be fixed stopper 300 card income under the effect of exerting external force a little fast in an installation, and can take out stopper 300 from spacing groove 120 fast under the effect of exerting external force a little at a dismantlement in-process, so realized quick installation and dismantlement stopper 300, its essence is indirect quick installation of having realized and dismantles heating panel 200, thereby production efficiency has been improved.

The plurality of heat sinks 400 are mounted on the heat sink 200 and are received in the heat dissipating through holes 110. For example, the plurality of heat sinks 400 are uniformly distributed on the heat dissipation plate 200, and all of the heat sinks 400 are received in the heat dissipation openings 110. It can be understood that the depth of the heat dissipating through holes 110 is large enough to accommodate all of the heat sinks 400, and therefore, in the embodiment, the depth of the heat dissipating through holes 110 is greater than or equal to the sum of the height of the heat dissipating plate 200 and the height of the heat sinks 400. In order to prevent heat of the heat sink 200 from being accumulated due to heat loss during the heat of the heat sink 200 is transferred to the heat sink 400, for example, the heat sink 400 and the heat sink 200 are integrally formed. Specifically, the heat sink 400 includes a heat slug 410 and a plurality of heat dissipation studs 420, the heat slug 410 is connected to the heat sink 200, and the plurality of heat dissipation studs 420 are disposed on the heat slug 410. For example, the heat dissipation block 410 is integrally formed with the heat dissipation plate 200. For improving the radiating efficiency, the quantity of radiator is corresponding with the quantity of lamp pearl 31 on the LED lamp plate 30, and each lamp pearl corresponds a radiator, that is to say, when the quantity of lamp pearl on the LED lamp plate 30 is five, the quantity of radiator also corresponds to five, and, the radiator corresponds the setting with lamp pearl on the LED lamp plate mutually back on the body, the radiator has increased the heat dissipation plate thickness in other words, the increase of knowing thickness can absorb more heat, so make the heat that the lamp pearl on the LED lamp plate produced can be a large amount of fast by the radiator absorption, it is specific to further absorb by a plurality of heat dissipation posts after being absorbed by the radiating block and give off to the outside.

The micro fan 500 is mounted in the receiving groove 130, and an input end of the micro fan 500 faces the heat dissipation channel 140. For example, the receiving groove 130 is disposed at a side of the heat dissipating port 110; preferably, the receiving groove 130 is provided inside the housing 100. In other embodiments, the receiving groove 130 may be a semi-closed cavity located inside the housing 100. In this embodiment, the micro fan 500 is a customized fan, and the overall appearance and volume thereof is processed to be suitable for the size of the accommodating slot 130, and only the function of rotating and blowing air is retained. The micro fan 500 is connected with an external power supply through a wire, so that when the micro fan 500 works, the input end of the micro fan 500 facing the heat dissipation channel 140 draws out air of the heat dissipation port 110, so that a space with relatively small air pressure is formed in the heat dissipation port 110, the space with relatively small air pressure can more stably and firmly cover the heat dissipation plate 200 on the heat dissipation port 110 under the action of atmospheric pressure, on the other hand, external air can enter the heat dissipation port 110 through a gap between the heat dissipation plate 200 and the housing 100, preferably, an air inlet channel is formed between the heat dissipation plate 200 and the housing 100, so that external cold air can enter the heat dissipation port 110 to absorb heat and the air heated under the action of the micro fan is sent out to the outside, thus forming a circulating air flow channel, and thus, the temperature of the heat dissipation channel 140 can be forcibly and rapidly reduced, thereby improving the heat dissipation efficiency of the heat dissipation plate 200.

Like this, be used for forming compact structure's heat radiation structure through casing 100, heating panel 200 and two stopper 300, heating panel 200 is used for installing the LED lamp plate, and the heat that the LED lamp plate produced like this will conduct to heating panel 200 and get into the conduction to in radiator 400. And, the micro fan 500 is used for absorbing heat in the heat sink through the heat dissipation channel 140 and allowing air-cooled air to overflow into the heat sink under the action of negative pressure during operation, so that under the dual heat dissipation driving of air-cooled air entering and heat flowing out from the heat dissipation channel 140, when the temperature of the heat sink 400 rises, heat can be quickly dissipated and conducted to the outside, and thus the heat dissipation efficiency is effectively improved in a forced heat dissipation manner by adding the micro fan 500.

Correspondingly, the heat dissipation plate 200 is provided with a fixing block 210, and the heat dissipation plate 200 is provided with a conductive through hole 220 adjacent to the fixing block 210. The clamping block 610 and the conductive sheet 620 are respectively inserted into the conductive through hole 220, and the clamping block 610 is connected to the fixing block 210. The conductive sheet 620 is electrically connected to the LED lamp panel 30. That is, the LED lamp panel 30 is disposed on the heat sink 200 and electrically connected to the conductive sheet 620. Like this, heat dissipation plate 200 and wiring board 600 can mutually support fixed connection through grip block 610 to realize the electric connection of LED lamp plate 30 and external power source under the effect of conducting strip 620.

In this embodiment, the conductive sheet 620 is embedded in the clamping block 610. Preferably, the wiring board 600 is made of plastic material, and the clamping block 610 is formed by integrally injection-molding the wiring board 600. Therefore, the shell of the LED lamp can be prevented from being electrified, and the safety performance of the product is improved.

Further, a clamping groove 211 is formed in one side, facing the conductive through hole 220, of the fixing block 210, and the tail end of the clamping block 610 is clamped into the clamping groove 211. For example, the end of the clamping block 610 is provided with a protrusion 611, and the protrusion 611 is snapped into the card slot 211. For example, the end of the clamping block 610 is integrally provided with the protrusion 611. For example, the card slot 211 is a groove with a rectangular structure. The protrusion 611 is, for example, a protrusion of a rectangular parallelepiped structure. So, can be so that under the effect of mutual buckle cooperation the wiring board 600 firm install on casing 100 and cover and establish heat dissipation opening 110, equipment convenient and fast has improved production efficiency.

For example, the clamping block 610 is provided with a terminal block 612, and the end of the conductive sheet 620 is exposed to form a contact with the bottom end of the terminal block 612. It can be understood that the number of the conducting strips 620 can be two, namely, the positive conducting strip and the negative conducting strip, correspondingly, the contact formed at the bottom end of the connecting block 612 can be divided into a positive contact and a negative contact, and the positive contact and the negative contact are respectively connected with the positive input contact and the negative input contact of the LED lamp panel in an abutting mode. Therefore, the connection between the LED lamp panel 30 and an external power supply can be better realized, and the LED lamp panel 30 can stably work. As for the connection between the conductive sheet 620 and the external power source, the connection can be achieved by setting a power interface, which is the prior art and will not be described herein.

For facilitating the mounting of the LED lamp panel, for example, the heat dissipation plate is provided with a fixing groove in which the LED lamp panel is disposed. For example, the LED lamp panel is welded in the fixing groove; in another example, the LED lamp panel is printed and disposed in the fixing groove. For example, the fixing groove is provided on a surface of the heat dissipating plate facing away from the heat dissipating through hole. It can be understood that the shape structure of the fixing groove can be the same as that of the LED lamp panel, and therefore the LED lamp panel can be conveniently installed. So, the heat that produces when the work behind the LED lamp plate access external power source can be quick conduct to the LED lamp plate and do not influence thermal conductivity. For example, the heat dissipation plate is provided with a fixing groove, and the LED lamp panel is disposed in the fixing groove. For example, the LED lamp panel is welded and arranged in the fixing groove.

Circular lamps and lanterns in above-mentioned each embodiment are used for fixing heating panel 200 and wiring board 600 on the both sides opening side of heat dissipation port 110 of casing 100 through grip block 610 to make heat dissipation port 110 form relatively confined heat dissipation space, so the heat that produces when the work of LED lamp plate 30 can get into heat dissipation port 110 through heating panel 200, and is absorbed by the air in heat dissipation port 110, and then conducts to the outside under the effect of circulation of air. The LED lamp is compact and reasonable in structure, can be rapidly installed outside, is high in heat dissipation efficiency, and effectively prolongs the service life of the LED lamp.

Further, in order to improve the heat dissipation efficiency, the micro fan comprises an upper micro fan and a lower micro fan, and the upper micro fan and the lower micro fan are respectively arranged at the top and the bottom of the shell. For example, the casing comprises a heat dissipation inner casing, a first built-in absorber plate, a second built-in absorber plate, an upper air guiding bent portion, a lower air guiding bent portion, an air inlet port, an air guiding guide groove, an upper air gathering cavity, a ventilation perforation, a middle air gathering cavity, a lower air gathering cavity, a reinforcing block, a heat dissipation fixing column, at least two positioning fixing portions and an air exhaust outlet. For example, the heat dissipation inner shell, the first internal heat absorption plate, the second internal heat absorption plate, the upper wind guiding bending portion, the lower wind guiding bending portion, the air inlet port, the wind guiding channel, the upper wind gathering cavity, the ventilation through hole, the middle wind gathering cavity, the lower wind gathering cavity, the reinforcing block, the heat dissipation fixing column, the at least two positioning fixing portions, the air exhaust outlet and the like are integrally formed by aluminum casting. In this embodiment, the heat dissipation inner casing is a wall of the accommodating groove. For example, the first and second built-in absorber plates are oppositely disposed. In this embodiment, the first internal heat absorbing plate and the second internal heat absorbing plate are arranged in parallel. For example, the housing includes two fixing portions respectively disposed near the top and the bottom of the heat dissipation inner housing. The upper air gathering cavity, the middle air gathering cavity and the lower air gathering cavity are communicated with each other. It can be understood that, in order to further improve the heat dissipation efficiency, the casing is provided with above-mentioned structure respectively in the both sides of heat dissipation opening, and miniature fan also corresponds the setting. Both sides can work simultaneously like this, have greatly improved the radiating efficiency.

For example, the heat dissipation inner shell is hollow cuboid structure, and the air inlet opening intercommunication heat dissipation channel for absorb the heat in the heat dissipation opening through heat dissipation channel. For example, the appearance of heat dissipation inner shell is square cavity frame body, adopts rigid plastic to make, and the hollow inside of heat dissipation inner shell is separated by two fixed part and is set into three plenum respectively by last to down in vertical direction: the upper wind gathering cavity, the middle wind gathering cavity and the lower wind gathering cavity are communicated through the ventilation through holes, and the lower wind gathering cavity is communicated with the middle wind gathering cavity through the lower miniature fan, so that the heat of the shell can be taken out of the environment outside the shell in an air cooling mode after the upper wind gathering cavity, the middle wind gathering cavity and the lower wind gathering cavity are communicated with each other and ventilate.

For example, the first built-in absorber plate, the second built-in absorber plate, the upper micro fan, the lower micro fan, the upper wind guiding bending portion, the lower wind guiding bending portion, the reinforcing block, the wind guiding groove, the heat dissipation fixing column, and the positioning fixing portion are disposed inside the heat dissipation inner shell. For example, the positioning fixing part close to the top of the heat dissipation inner shell and the top of the heat dissipation inner shell form the upper wind gathering cavity. For example, the positioning fixing part close to the bottom of the heat dissipation inner shell and the bottom of the heat dissipation inner shell form the lower wind gathering cavity. For example, the middle air collecting cavity is formed between the positioning fixing part close to the bottom of the heat dissipation inner shell and the heat dissipation fixing column.

It can be understood that a plurality of radiators have absorbed the heat of the LED lamp panel and the air in the heating heat dissipation opening forms hot-blastly, consequently in order to control by hot-blastly from the overhead wind chamber that gathers that heat dissipation channel gets into to through in put gather wind chamber by first built-in absorber plate and the built-in absorber plate absorption heat back of second, a small part of hot-blastly from the overhead wind chamber of gathering flows, for example, air inlet opening, induced air guide slot, overhead micro fan and last wind-guiding flexion etc. set up in overhead wind chamber of gathering. For example, the air inlet opening is opened in a lateral wall of the overhead air gathering chamber, and a plurality of grids arranged in an array manner are further arranged along the periphery of the air inlet opening in an extending manner and used for preventing cockroaches, mosquitoes and the like from entering the air inlet opening. Correspondingly, the overhead micro fan is arranged on the other side wall of the overhead air gathering cavity of the relative air inlet port, an induced air guide groove is formed between the overhead micro fan and the air inlet port through a plastic plate, namely the induced air guide groove is communicated with the air inlet port, the induced air guide groove is arranged in a sealing mode, and the induced air guide groove is only communicated with the overhead micro fan and the air inlet port. Therefore, when the upper miniature fan works, the pressure intensity of the induced air guide groove on the two sides of the upper miniature fan and the air inlet opening is unequal, and the pressure intensity of the induced air guide groove on the side of the upper miniature fan is smaller than the pressure intensity of the induced air guide groove on the side of the air inlet opening, so that the air inlet opening can continuously feed hot air for the upper miniature fan to dissipate heat. In order to facilitate rapid flowing to the ventilation perforation, for example, an upper air guiding bending portion is further disposed on an inner side wall of the upper air gathering chamber, the inner side wall is close to one side of the upper micro fan, the upper air guiding bending portion is made of an aluminum alloy material, and the upper air guiding bending portion is a portion with an arc-shaped surface or a hemispherical or circular arc-shaped groove, the inner surface of the portion with the arc-shaped surface or the hemispherical or circular arc-shaped groove is rough, and a hemispherical or circular arc-shaped opening of the portion faces the ventilation perforation, so that when the upper micro fan works, hot air blows towards the upper air guiding bending portion, partial heat can be absorbed by the rough surface, and the hot air continues to turn back to the ventilation perforation while being absorbed by the upper air guiding bending portion and flows to.

For example, cold air enters the upper air gathering cavity, passes through the ventilation perforation and then enters the middle air gathering cavity. Two positioning fixing parts which are positioned on the lower side of the upper wind gathering cavity inside the heat dissipation inner shell form the middle wind gathering cavity, for example, the positioning fixing parts are of plate-shaped structures and are made of aluminum alloy materials. In addition, the first built-in heat absorbing plate is mounted on the positioning fixing part close to one side of the upper air gathering cavity, and the first built-in heat absorbing plate is further connected with the second built-in heat absorbing plate through the reinforcing block so as to reinforce the relative fixing positions of the first built-in heat absorbing plate and the second built-in heat absorbing plate. In order to enhance the heat washing effect of the first internal heat absorbing plate, the first internal heat absorbing plate is made of sheet aluminum alloy, for example, the first internal heat absorbing plate made of sheet aluminum alloy is formed into a disc-shaped structure by a winding processing mode. For example, the structure of the first internal heat absorbing plate can be made of a hollow double-ring winding structure, a double-layer winding structure, a single-layer disc winding structure, and the like. Preferably, the first built-in heat absorption plate with a double-layer winding structure and high-efficiency heat absorption of the flaky aluminum alloy is adopted, so that the heat absorption efficiency of the first built-in heat absorption plate is improved, and the heat dissipation efficiency is further improved.

It can be understood, for make LED lamp plate and the outside circular telegram of installing on the heating panel, the casing is provided with the wire, the casing be provided with wire electric connection's power input end, be used for inserting external power source, the wire is used for bridging external power source and LED lamp plate, consequently, in order to promote the security performance of casing, the built-in absorber plate of second still is provided with the fuse, for example, the fuse includes the fuse, for example, the fuse is installed at power input end, make when the electric current of installing the LED lamp plate on the heating panel is unusual. For example, when the voltage rises or the current is overloaded, the fuse fuses to cut off the electrical connection between the power supply and the LED lamp panel installed on the heat dissipation plate, so that the safe operation of the circuit is ensured. For example, install the LED lamp plate on the heating panel and still be provided with safety switch, for example, safety switch includes that two kinds of expend with heat and contract with cold different sheetmetals of coefficient press the bimetallic strip of making together, for example, be provided with power button switch in the effect scope of the deformation of bimetallic strip, bimetallic strip effect is at power button switch when bimetallic strip is heated and takes place deformation, when the LED lamp plate of installing on the heating panel leads to the high temperature because of the heat dissipation is bad promptly, safety switch can the power failure to guarantee circuit safety operation.

For example, the heat flowing through the middle air-gathering cavity is partially absorbed, and the other part of the heat flows from the middle air-gathering cavity to the lower air-gathering cavity through the lower micro-fan under the action of the pressure difference of the air flow. Namely, when the lower miniature fan works, the pressure difference is generated between the middle air gathering cavity and the lower air gathering cavity, and under the action of the pressure difference, hot air in the middle air gathering cavity flows to the lower air gathering cavity. It can be understood that the lower wind gathering cavity is composed of a positioning fixing part at the bottom of the middle wind gathering cavity and the bottom of the shell. After the hot air flow of the middle air gathering cavity enters the lower air gathering cavity, the hot air flows to the exhaust outlet under the action of the lower air guide bending part, and finally the hot air flow with heat is exhausted out of the shell through the exhaust outlet. Therefore, the heat gathered by the heat dissipation body can be quickly and efficiently dissipated to the outside, and the heat dissipation efficiency is greatly improved.
