For example, the voice-controlled lighting system includes a plurality of sound sensors, for example, a plurality of sound sensors are numbered in order from the sound sensor 1, the sound sensor 2, the sound sensor 3, the sound sensor 4 to the sound sensor N. Correspondingly, the LED lamps are numbered from the LED lamp 1, the LED lamp 2, the LED lamp 3, the LED lamp 4 to the LED lamp N in sequence.

The applicable environment of the LED lamp is wider and wider, and the heat generated by the LED lamp during working not only influences the lighting effect of the LED, but also influences the service life of the LED. However, the traditional heat dissipation structure is simple, the heat dissipation efficiency is low, the heat accumulated on the LED lamp beads is difficult to radiate outside, the lighting effect of the LED lamp is reduced in the past for a long time, and the service life of the LED lamp is influenced. To improve the service life of the LED lamp, for example, the LED lamp includes: radiator and LED lamp plate. The heat sink includes: the heat dissipation device comprises a shell, a heat dissipation plate, two limiting blocks, a plurality of heat dissipation bodies, a micro fan and a wiring board. The shell can be made of aluminum alloy materials, and can also be formed by compounding aluminum alloy and plastic. The shell is used for providing an installation supporting function and is used for assembling and installing the heat dissipation plate, the two limiting blocks, the plurality of heat dissipation bodies and the micro fan; simultaneously, the casing also is used for installing in the outside to combine the LED lamp plate to realize the illumination function. The heat dissipation plate can be made of aluminum alloy materials or can be formed by compounding aluminum alloy and plastic. The heating panel is used for installing the LED lamp plate, integrates the PCB circuit board that has LED lamp pearl promptly to make the heat accessible heating panel conduction to the outside that the LED lamp plate produced at the during operation. The two limiting blocks can be made of aluminum alloy materials or can be formed by compounding aluminum alloy and plastic. The two limiting blocks are mainly used for being matched with the heat dissipation plate to fix the heat dissipation plate on the shell. The heat radiator is made of aluminum alloy materials and used for absorbing heat conducted by the heat radiating plate and conducting the heat. The micro fan is used for supplying air to the shell to dissipate the heat accumulated by the heat dissipation body. The wiring board is made of aluminum alloy materials, and can also be formed by compounding aluminum alloy and plastic. The wiring board is used for connecting an external power supply and is electrically connected with the LED lamp panel, and is used for matching with the heat dissipation plate to fix the heat dissipation plate on the shell.

The shell is provided with a through heat dissipation port. For example, the heat dissipating through-openings have a rectangular cross-section, for example, the heat dissipating through-openings have a circular cross-section, which facilitates mold-open production. The shell is also provided with limiting grooves on two opposite sides of the heat dissipation port. For example, the retaining groove has a rectangular cross-section. The limiting groove is communicated with the heat dissipation through hole. In other words, the shell is provided with a limiting groove and a heat dissipation through hole which are communicated with each other, and the limiting groove and the heat dissipation through hole are communicated with each other to form a whole. In this embodiment, the length of spacing groove is less than the length of heat dissipation opening, has the shorter spacing groove of length in the outside of heat dissipation opening like this to in two stopper of installation and then fixed heating panel.

For example, the housing is a rectangular parallelepiped structure; as another example, the housing is cube; in another example, the housing is a triangular prism. Preferably, the housing is a rectangular parallelepiped structure. The accepting groove and the heat dissipation channel are arranged on the shell, the accepting groove is communicated with the heat dissipation port through the heat dissipation channel, and the accepting groove, the heat dissipation channel and the heat dissipation port are communicated with each other, so that air can circulate in the accepting groove, the heat dissipation channel and the heat dissipation port, and the heat gathered in the heat dissipation port can be taken away in time.

For example, the housing is provided with a threaded hole, and the housing is installed on a corridor of the whole office building, a corridor of the whole mall or a ceiling of a corridor of the whole administrative building through the threaded hole. For example, the number of the screw holes is two, and the two screw holes are respectively arranged on two sides of the shell. In this embodiment, the two threaded holes are respectively disposed in the areas of the opposite corners of the two sides of the housing. It can be understood that after the shell is installed on the external lamp holder through the threaded hole, a plurality of LED lamps are installed on the ceiling of the corridor of the whole office building, the corridor of the whole market or the corridor of the whole administrative building and the light-emitting colors of the LED lamps are set, so that colorful combined lamps can be formed, and the LED lamps are installed on the ceiling of the corridor of the whole office building, the corridor of the whole market or the corridor of the whole administrative building, so that the LED lamp holder is convenient and quick to use and high in efficiency.

For example, the heat dissipation plate has a rectangular parallelepiped structure. The radiating plate covers and is provided with a radiating through hole. For example, the heat dissipation plate is located at an opening side of the heat dissipation port and covers the heat dissipation port. For example, the heat dissipation plate and the heat dissipation port are engaged with each other. That is to say, the length and the width of heating panel equal the length and the width of heat dissipation opening, can make the heating panel cover the heat dissipation opening completely like this to after the heating panel covers the heat dissipation opening completely, the surface parallel and level at the surface and the heat dissipation opening edge place of heating panel, thereby make the more compact reasonable order of overall structure. In this embodiment, the heat dissipation plate has a plate-like structure made of an aluminum alloy material. For example, the heat radiating plate is provided with a fixing block, and for example, the heat radiating plate is integrally formed with cast aluminum. The heat dissipation plate is provided with a conductive through hole adjacent to the fixing block, and the fixing block and the conductive through hole are jointly used for connecting the wiring board, so that the heat dissipation plate and the wiring board are mutually matched and fixedly connected.

For example, the limiting block is of a cuboid structure. For example, the heat dissipation plate and the two stoppers are integrally formed. The two limiting blocks are respectively arranged on two sides of the heat dissipation plate, and each limiting block is correspondingly embedded in one limiting groove. The limiting block is matched with the limiting groove. For realizing quick installation and dismantling the heating panel, for example, the tip of spacing groove is provided with the block arch, and the tip correspondence of stopper has seted up the block recess, and the block arch card is gone into in the block recess. For example, the both ends of spacing groove are provided with the block arch respectively, the both ends of stopper correspond respectively and have seted up the block recess, can utilize the block protruding to be connected with the block of block recess like this, can fix the stopper card into at the spacing groove under the effect of external force is applyed a little fast in the installation, and can take out the stopper from the spacing groove fast under the effect of external force is applyed a little at a dismantlement in-process, so realized quick installation and dismantlement stopper, its essence is indirect quick installation and dismantlement heating panel of having realized, thereby production efficiency has been improved.

The plurality of heat dissipation bodies are arranged on the heat dissipation plate and are contained in the heat dissipation through openings. For example, the plurality of heat dissipation bodies are uniformly distributed on the heat dissipation plate, and all the heat dissipation bodies are accommodated in the heat dissipation through holes. It can be understood that the depth of the heat dissipation through hole is large enough to accommodate all the heat dissipation bodies, so in this embodiment, the depth of the heat dissipation through hole is greater than or equal to the sum of the height of the heat dissipation plate and the height of the heat dissipation body. In order to avoid heat accumulation of the heat dissipation plate due to heat loss in the process of transferring heat of the heat dissipation plate to the heat dissipation body, for example, the heat dissipation body and the heat dissipation plate are integrally formed. Specifically, the radiator includes radiating block and a plurality of heat dissipation post, and the radiating block is connected with the heating panel, and a plurality of heat dissipation posts set up in the radiating block. For example, the heat dissipation block is integrally formed with the heat dissipation plate. For improving the radiating efficiency, the quantity of radiator is corresponding with the quantity of the lamp pearl on the LED lamp plate, and each lamp pearl corresponds a radiator, that is to say, when the quantity of the lamp pearl on the LED lamp plate 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 like this, 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 absorbed by the radiator by a large amount of fast, 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 is installed in the accommodating groove, and the input end of the micro fan faces the heat dissipation channel. For example, the accommodating groove is arranged on the side of the heat dissipation through hole; preferably, the housing groove is provided inside the housing. In other embodiments, the receiving groove may be a semi-closed cavity located inside the housing. In this embodiment, the micro fan is a customized fan, and the overall appearance and volume of the micro fan is processed to be suitable for the size of the accommodating groove, and only the function of rotating and blowing air is kept. The micro fan is connected with an external power supply through a lead, so that when the micro fan works, the input end of the micro fan facing the heat dissipation channel can draw out the air of the heat dissipation through hole, so that a space with relatively small air pressure is formed in the heat dissipation through hole, the space with relatively small air pressure can more stably and firmly cover the heat dissipation plate under the action of atmospheric pressure on one hand, on the other hand, external air can enter the heat dissipation through hole through a gap between the heat dissipation plate and the shell, preferably, an air inlet channel is formed between the heat dissipation plate and the shell, so that the external cold air can enter the heat dissipation through hole to absorb heat and the air heated by the micro fan is sent out to the outside, thus forming a circulating air flow channel, therefore, the temperature of the heat dissipation channel can be forcibly and rapidly reduced, and the heat dissipation efficiency of the heat dissipation plate is improved.

So, be used for forming compact structure's heat radiation structure through casing, heating panel and two stoppers, the heating panel is used for installing the LED lamp plate, and the heat that the LED lamp plate produced like this will conduct to the heating panel and get into the conduction to the radiator in. And the miniature fan is used for absorbing heat in the heat dissipation body through the heat dissipation channel and enabling air-cooled air to overflow into the heat dissipation body under the action of negative pressure during working, so that the heat can be quickly dissipated and conducted to the outside through air-cooled air entering and dual heat dissipation driving of heat flowing out from the heat dissipation channel when the temperature of the heat dissipation body rises, and the heat dissipation efficiency is effectively improved in a forced heat dissipation mode through the increase of the miniature fan.

The wiring board is located another opening side of heat dissipation opening and covers and establishes the heat dissipation opening, and the wiring board is provided with grip block and conducting strip, and the conducting strip sets up in the grip block. Correspondingly, the heat dissipation plate is provided with a fixing block, and the heat dissipation plate is provided with a conductive through hole adjacent to the fixing block. The clamping block and the conducting strip are respectively penetrated with a conducting through hole, and the clamping block is connected with the fixing block. Conducting strip and LED lamp plate electric connection. That is to say, the LED lamp panel is disposed on the heat dissipation plate and electrically connected to the conductive sheet. Like this, heating panel and wiring board can mutually support fixed connection through the grip block to realize LED lamp plate and external power source's electric connection under the effect of conducting strip.

In this embodiment, the conducting strip sets up inside the grip block through the mode of burying the grip block. Preferably, the wiring board is made of plastic materials, and the wiring board is integrally injection-molded to form the clamping block. Therefore, the shell of the LED lamp can be prevented from being electrified, and the safety performance of the product is improved.

Furthermore, a clamping groove is formed in one side, facing the conductive through hole, of the fixing block, and the tail end of the clamping block is clamped into the clamping groove. For example, the end of the clamping block is provided with a protrusion, and the protrusion is clamped into the clamping groove. For example, the end of the clamping block is integrally provided with a projection. For example, the clamping groove is a groove with a rectangular structure. For example, the projections are projections of a rectangular parallelepiped structure. So, can be so that the wiring board firm install on the casing and cover and establish the heat dissipation opening through buckle complex effect each other down, equipment convenient and fast has improved production efficiency.

For example, the clamping block is provided with a junction block, and the tail end of the conducting strip is exposed to form a contact with the bottom end of the junction block. It can be understood that the quantity of conducting strip can set up two, is anodal conducting strip and negative pole conducting strip respectively, and is corresponding, and the bottom of junction block forms the contact and can divide into anodal contact and negative pole contact, thereby anodal contact and negative pole contact respectively with the positive negative pole input contact butt electric connection of LED lamp plate. Therefore, the LED lamp panel can be better connected with an external power supply, and the LED lamp panel can stably work. As for the connection of the conducting strip and the external power supply, the connection can be realized by a power interface, which is the prior art and is not described herein again.

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.

The LED lamps and lanterns in above-mentioned each embodiment are used for fixing heating panel and wiring board on the two opening sides of the heat dissipation opening of casing through the grip block to make the heat dissipation opening form the heat dissipation space of relative confined, so the heat that produces when the LED lamp plate during operation can get into the heat dissipation opening through the heating panel, and by the intraoral air absorption of heat dissipation opening, and then conduct 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.

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.
