Description

Technical Field

[0001] This utility model relates to the field of LED packaging technology, specifically to an LED packaging structure with heat dissipation function. Background Technology

[0002] LED (Light Emitting Diode) packaging refers to the packaging of light-emitting chips. It is quite different from integrated circuit packaging. LED packaging not only needs to protect the chip but also needs to allow light to pass through. Therefore, LED packaging has special requirements for packaging materials. Existing LED packaging structures can lead to excessively high temperatures after prolonged use, causing performance degradation and failing to meet people's needs.

[0003] Publication No. CN216354287U discloses an antistatic LED packaging structure. Through the arrangement of a copper plate, thermal grease, and a heat sink, the copper plate absorbs heat from the thermally conductive copper pillars. The thermally conductive grease acts as a medium, adhering to the large area of ​​the copper plate and heat sink. The heat sink effectively absorbs heat from the copper plate and thermally conductive copper pillars, effectively cooling the LED packaging structure and preventing high temperatures from affecting its performance. The use of high-temperature resistant tape and a resin coating further protects the LED packaging structure, preventing oxidation-induced degradation of its overall performance and reliability, improving its airtightness, extending its lifespan, and providing effective antistatic protection. However, this patent still has the following problems in practical use:

[0004] Although this antistatic LED packaging structure uses a copper plate, thermal grease, and heat sink, the copper plate can absorb the heat-conducting copper pillars, the thermal grease acts as a medium to adhere to the large area of ​​the copper plate and heat sink, and the heat sink can effectively absorb the heat from the copper plate and thermal pillars, the heat sink can only transfer heat and does not have a cooling function itself. Therefore, it cannot dissipate heat in a timely manner, which will affect the heat dissipation effect of the heat sink and is not conducive to cooling the LED packaging structure.

[0005] Therefore, an LED packaging structure with heat dissipation function is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an LED packaging structure with heat dissipation function, in order to solve the problem that the heat sinks mentioned in the background art can only transfer heat and do not have the function of cooling themselves. Therefore, they cannot dissipate heat in time, which will affect the heat dissipation effect of the heat sink and is not conducive to cooling the LED packaging structure.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an LED packaging structure with heat dissipation function, including a packaging heat dissipation mechanism and an LED body installed inside the packaging heat dissipation mechanism;

[0008] The top of the encapsulation heat dissipation mechanism is provided with a mounting mechanism, and the top of the mounting mechanism is provided with a clamping plate.

[0009] Also includes:

[0010] The encapsulation and heat dissipation mechanism includes a clamping plate, a lamp holder is fixedly installed inside the clamping plate, and the LED body is fixedly installed at the bottom of the lamp holder;

[0011] The lamp holder has circulating fans symmetrically installed on both sides, and a first heat sink is fixedly installed on the top of the lamp holder.

[0014] Preferably, a lampshade is provided at the bottom of the sealing ring, and mounting brackets are symmetrically installed on both sides of the bottom of the housing. A stabilizing bracket is fixedly installed on the top of the mounting bracket, and a reinforcing sliding rod is fixedly installed inside the mounting bracket.

[0015] Preferably, a reinforcing sliding sleeve is slidably connected to the outer side of the reinforcing sliding rod, an installation spring is fixedly installed on one side of the reinforcing sliding sleeve, a first installation hook is fixedly installed at the bottom of the reinforcing sliding sleeve, and an unlocking connecting rod is fixedly installed between the two first installation hooks.

[0016] Preferably, a second mounting hook is symmetrically installed on both sides of the top of the lampshade, and the second mounting hook is engaged with the first mounting hook.

[0017] Preferably, the mounting mechanism includes a mounting base plate, which is fixedly mounted on the top of the housing. Clamping rotating supports are fixedly mounted on all four sides of the top of the housing. A clamping rotating rod is rotatably connected to the top of the clamping rotating support, and a clamping sliding sleeve is rotatably connected to the top of the clamping rotating rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This LED packaging structure with heat dissipation function can absorb heat when it moves between the first and second heat sinks and move towards the top of the heat sink. The heat can then be dissipated through the cooling fan and air guide plate, thereby improving the heat dissipation effect of the LED packaging structure. By pressing the mounting base plate upward, under the action of the clamping rotating support and the clamping rotating rod, the clamping rotating rod drives the clamping sliding sleeve to slide on the outside of the clamping sliding rod, causing the clamping sliding sleeve to drive the clamping arm to unfold. Under the elastic force of the clamping spring, the clamping plate is clamped and fixed. The specific details are as follows:

[0020] 1. By setting up a heat dissipation mechanism, the circulating fans on both sides of the lamp holder can circulate the heat dissipated by the LED body inside the housing. When the heat moves between the first and second heat sinks, it can be absorbed and moved to the top of the heat sink. The heat can be discharged through the cooling fan and the air guide plate, thereby improving the heat dissipation effect of the LED packaging structure. By pushing the lamp cover upward, the second mounting hook pushes the first mounting hook, which in turn drives the reinforcing sliding sleeve to squeeze the mounting spring. When the first mounting hook and the second mounting hook are engaged, the lamp cover can be fixed in place. The sealing ring improves the sealing effect of the LED packaging structure.

[0021] 2. By setting up the installation mechanism, the clamping plate can be fixed in the designated position using the mounting bolts. By pressing the mounting base plate upward, the clamping rotating support and the clamping rotating rod cause the clamping rotating rod to drive the clamping sliding sleeve to slide on the outside of the clamping sliding rod. This causes the clamping sliding sleeve to drive the clamping arm to unfold. Under the elastic force of the clamping spring, the clamping plate is clamped and fixed, which facilitates the installation of the housing. Attached Figure Description

[0030] Please see Figures 1-6This utility model provides a technical solution: an LED packaging structure with heat dissipation function, including a packaging heat dissipation mechanism 1 and an LED body 103 installed inside the packaging heat dissipation mechanism 1.

A second heat sink 107 is fixedly installed on the bottom of the sealing support 106. A heat sink 108 is fixedly installed on the top of the sealing support 106. Several air guide plates 109 are fixedly installed on the top of the heat sink 108. Cooling fans 110 are symmetrically installed on both sides of the top of housing 101 near the heat sink 108. A sealing ring 111 is fixedly installed on the bottom of housing 101. A lamp cover 112 is provided at the bottom of the sealing ring 111. Mounting brackets 113 are symmetrically installed on both sides of the bottom of housing 101. A stabilizing bracket 114 is fixedly installed on the top of the mounting bracket 113.

A mounting spring 117 is fixedly installed on one side of the reinforcing sliding sleeve 116. A first mounting hook 118 is fixedly installed at the bottom of the reinforcing sliding sleeve 116. An unlocking connecting rod 119 is fixedly installed between the two first mounting hooks 118. Second mounting hooks 120 are symmetrically installed on both sides of the top of the lamp cover 112. The second mounting hooks 120 are engaged with the first mounting hooks 118. The circulating fans 104 on both sides of the lamp holder 102 can circulate the heat dissipated by the LED body 103 inside the housing 101. When the heat moves to the first heat sink 1... When the LED is positioned between the 05 and the second heat sink 107, it can absorb heat and move towards the top of the heat sink 108. The heat can be dissipated through the cooling fan 110 and the air guide plate 109, thereby improving the heat dissipation effect of the LED packaging structure. By pushing the lamp cover 112 upward under the action of the second mounting hook 120, the second mounting hook 120 pushes the first mounting hook 118, causing the first mounting hook 118 to drive the reinforcing sliding sleeve 116 to squeeze the mounting spring 117.

[0031] The mounting mechanism 2 includes a mounting base plate 201, which is fixedly mounted on the top of the housing 101. Clamping rotating supports 202 are fixedly mounted on all four sides of the top of the housing 101. A clamping rotating rod 203 is rotatably connected to the top of the clamping rotating support 202. A clamping sliding sleeve 204 is rotatably connected to the top of the clamping rotating rod 203. A clamping sliding rod 205 is slidably connected inside the clamping sliding sleeve 204. A clamping spring 206 is fixedly mounted on one side of the clamping sliding sleeve 204. A clamping bracket 207 is fixedly mounted on the outside of the clamping sliding rod 205.

The clamping plate 209 is threaded with mounting bolts 210 around its inner perimeter. The clamping plate 209 is fixed in the designated position by the mounting bolts 210. By pressing the mounting base plate 201 upward, under the action of the clamping rotating support 202 and the clamping rotating rod 203, the clamping rotating rod 203 drives the clamping sliding sleeve 204 to slide on the outside of the clamping sliding rod 205, so that the clamping sliding sleeve 204 drives the clamping arm 208 to unfold. Under the elastic force of the clamping spring 206, the clamping plate 209 is clamped and fixed, which facilitates the installation of the housing 101.

[0032] Working principle: Before using this LED packaging structure with heat dissipation function, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6 As shown, firstly, the clamping plate 209 is fixed in the designated position using the mounting bolts 210. Then, by pressing the mounting base plate 201 upwards, under the action of the clamping rotating support 202 and the clamping rotating rod 203, the clamping rotating rod 203 drives the clamping sliding sleeve 204 to slide outside the clamping sliding rod 205, causing the clamping sliding sleeve 204 to drive the clamping arm 208 to unfold. Under the elastic force of the clamping spring 206, the clamping plate 209 is clamped and fixed, facilitating the installation of the housing 101. Secondly, the circulating fans 104 on both sides of the lamp holder 102 enable the heat dissipated by the LED body 103 to circulate inside the housing 101. When the heat moves to the first... When the heat sink 105 is between the second heat sink 107, it can absorb heat and move towards the top of the heat sink 108. The heat can be discharged through the cooling fan 110 and the air guide plate 109, thereby improving the heat dissipation effect of the LED packaging structure. By pushing the lamp cover 112 upward, under the action of the second mounting hook 120, the second mounting hook 120 pushes the first mounting hook 118, causing the first mounting hook 118 to drive the reinforcing sliding sleeve 116 to squeeze the mounting spring 117. When the first mounting hook 118 and the second mounting hook 120 are engaged, the lamp cover 112 can be installed and fixed. The sealing effect of the LED packaging structure is improved by the sealing ring 111.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
