Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, specifically to an LED lamp with a heat dissipation structure. Background Technology

[0002] LED lighting fixtures have been widely used in various lighting fields due to their high efficiency, energy saving, and long lifespan. However, LED chips generate a lot of heat during operation. If heat cannot be dissipated effectively and in a timely manner, it will lead to reduced LED luminous efficacy, color temperature drift, and even shortened lifespan. Existing LED lamp heat dissipation structures are mostly simple heat sinks or heat dissipation fins. These heat sinks or fins mainly function on the housing and are often integrated with the housing. While the heat dissipation structure is fixed, the fins located on the periphery of the housing are also susceptible to contamination from the external environment and may even deform or break due to impacts, directly affecting the stability of the heat dissipation effect and lacking structural flexibility. Utility Model Content

[0003] The purpose of this utility model is to provide an LED lamp with a heat dissipation structure. This LED lamp can ensure the stability of heat dissipation effect, and the heat dissipation component is not easily contaminated by the external environment. It is convenient to disassemble, clean and replace, further improving the heat dissipation effect of the LED lamp assembly. It also facilitates subsequent replenishment of thermal grease and replacement of the LED lamp assembly, improving structural flexibility and applicability.

[0004] The technical solution adopted by this utility model to solve the above problems is:

[0005] An LED lamp with a heat dissipation structure includes a detachably connected lamp cap and a lamp cover. An LED lamp assembly is installed inside the lamp cap. A heat dissipation component is installed on the lamp cap located inside the lamp cover. The heat dissipation component includes a heat dissipation plate with several sets of heat dissipation fins arranged on it. The heat dissipation plate is slidably mounted on the lamp cap via multiple sets of connecting rods provided on the lamp cap, and the heat dissipation fins pass through the lamp cap and abut against the LED lamp assembly. Multiple sets of locking parts for adjusting the position of the heat dissipation plate are rotatably provided on the connecting rods.

[0006] Preferably, the connecting rod is also fitted with a compression spring, which is located on the side away from the lamp cap and its corresponding two ends abut against the heat sink and the locking member, respectively.

[0007] Preferably, a stop is provided between the lamp cap and the heat sink, and the stop is detachably mounted on the heat sink.

[0008] Preferably, the heat dissipation assembly further includes a cooling fan disposed on one side of the heat sink, and the cooling fan is detachably mounted on the connecting rod via a connecting bracket disposed thereon.

[0009] Preferably, a flared outer cover can be detachably installed on the connecting bracket located around the cooling fan, and the outer cover has several sets of through holes.

[0010] Preferably, the heat sink has a groove inside and a connecting part is provided on the groove. The connecting part is set as either a protrusion plate along both sides of the groove for connecting two adjacent heat sinks or a protrusion in the groove for connecting two adjacent heat sinks. The protrusion is set in a rhombus shape.

[0011] Preferably, the lamp cover is provided with several sets of spaced through grooves, and a cover plate can be detachably installed on the lamp cover located outside the through grooves, with an opening on the cover plate.

[0012] Preferably, the lamp cap located on the periphery of the LED lamp group is also detachably equipped with a diffuser cup, a transparent sheet, and a fixing ring.

[0013] Compared with the prior art, this utility model has the following advantages and effects:

[0014] This utility model relates to an LED lamp with a heat dissipation structure. In actual use, several sets of heat sinks on the heat sink plate can be combined with thermally conductive silicone grease applied to the corresponding mounting surfaces of the lamp cap to ensure stable heat dissipation. Furthermore, the heat sinks can be detachably connected to the connecting rod of the lamp cap via the rotation of the locking mechanism. The heat dissipation component and the lamp cap are designed as separate units. The heat dissipation component's installation method within the lamp cap is less susceptible to external environmental contamination, and under the protection of the lamp cover and lamp cap, the heat sinks are less prone to deformation or breakage, facilitating disassembly, cleaning, and replacement. It can also be combined with a structure featuring several sets of heat dissipation fins arranged on the lamp cap, according to usage requirements. The two heat dissipation methods—the heat dissipation component and the heat dissipation fins inside and outside the lamp cap—further improve the heat dissipation effect of the LED lamp assembly. Additionally, when the heat sink plate is disassembled, the thermally conductive silicone grease applied to the heat sinks can be used... By checking the status, if subsequent replenishment of thermal grease or replacement of LED light groups is required, the bolts used to lock the LED light board can be loosened in advance. Combined with the structure of the heat sink, it can slide towards the lamp cap, allowing the heat sink to protrude into the groove and support the LED light group. This keeps the LED light group away from the corresponding mounting end face of the lamp cap and the grease-like thermal grease applied to it, making it easier to remove the LED light group from inside the lamp cap. At the same time, the arrangement of several heat sinks, compared with the traditional operation process due to the narrow internal space of the lamp cap, effectively reduces the probability of damage to the LED light group caused by tilting or even collision during disassembly. It also appropriately reduces unnecessary contamination of the thermal grease during operation, facilitating subsequent replenishment of thermal grease and replacement of LED light groups, improving structural flexibility and applicability.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0023] See Figure 1-5 This embodiment relates to an LED lamp with a heat dissipation structure, including a detachably connected lamp cap 1 and lamp cover 2. An LED lamp group 3 is installed inside the lamp cap 1. A heat dissipation component 4 is installed on the lamp cap 1 located inside the lamp cover 2. The heat dissipation component 4 includes a heat dissipation plate 41 with several sets of heat dissipation fins 411 arranged thereon. The heat dissipation plate 41 is slidably disposed on the lamp cap 1 by multiple sets of connecting rods 11 provided on the lamp cap 1, and the heat dissipation fins 411 pass through the lamp cap 1 and abut against the LED lamp group 3. Multiple sets of locking parts 111 for adjusting the position of the heat dissipation plate 41 are rotatably disposed on the connecting rods 11.

[0024] Specifically in this embodiment, such as Figure 1 The overall structural design of this type of LED lamp with a heat dissipation structure is shown in the figure. Figure 2The conventional connection method of the traditional LED lamp shown includes an LED lamp group 3 formed by a lamp board 32 with one or more sets of LED lamp beads 31, which can be detachably installed in the lamp cap 1 by bolts. The corresponding circuits can pass through multiple sets of slots 12 opened on the corresponding wall surface of the lamp cap 1, and are connected to the adapter circuit board 20 located in the lamp cover 2 by bolts. The corresponding circuits of the circuit board 20 can pass through multiple sets of second slots 21 opened on the corresponding wall surface of the lamp cover 2, realizing the lighting and turning-off process of the LED lamp group 3 in the lamp cap 1 under external power supply. Unlike the traditional LED lamp, the lamp cap 1 in the lamp cover 2 is equipped with a heat dissipation component 4. Specifically, the wall surface of the lamp cap 1 used for mounting and fitting the LED lamp group 3 is... Multiple sets of sliding grooves 13 are provided on the surface for the heat sink 411 to slide through. The heat sink 41 can slide through the connecting rod 11 via the protrusions 412 at both ends and the third slots 413 on them. At the same time, the locking piece 111 on the connecting rod 11 can be rotated and adjusted by means of a threaded connection on the connecting rod 11 located on the upper and lower sides of the protrusions 412, so that the corresponding end face of several sets of heat sinks 411 on the heat sink 41 is flush with the end face of the lamp cap 1 for mounting the LED lamp group 3. The locking piece 111 on the connecting rod 11 located on the upper and lower sides of the protrusions 412 can lock the position of the heat sink 41. Subsequently, the end face of the lamp cap 1 for mounting the LED lamp group 3 and the heat sink in the sliding groove 13 are flush with it. Thermal grease can be evenly applied to the corresponding end face of the heat sink 411. After the thermal grease is applied, the LED light assembly 3 is installed and fixed to the corresponding end face inside the lamp cap 1 using bolts. Finally, the lamp cover 2 is installed and fixed to the lamp cap 1 on the periphery of the heat sink 41 using bolts. In actual use, the several heat sinks 411 on the heat sink 41 can be combined with the thermal grease applied to the corresponding mounting end face of the lamp cap 1 to ensure the stability of the heat dissipation effect. The heat sinks 411 can be detachably connected to the connecting rod 11 of the lamp cap 1 by the rotation of the locking piece 111. The heat dissipation assembly 4 and the lamp cap 1 are designed as separate structures. The installation method of the heat dissipation assembly 4 inside the lamp cap 1 is not easily affected by external environmental pollution and also ensures the stability of the lamp. Under the protection of cover 2 and lamp cap 1, the heat sink 411 is not prone to deformation or even breakage, facilitating disassembly, cleaning, and replacement. Furthermore, based on the structural design of the lamp cap 1 with several sets of heat dissipation fins 14 arranged on it, the two heat dissipation methods—heat dissipation component 4 and heat dissipation fins 14 inside and outside the lamp cap 1—can further improve the heat dissipation effect on the LED light assembly 3. Additionally, when disassembling the heat sink 41, the condition of the thermal grease applied to the heat sink 411 can be checked. If subsequent replenishment of thermal grease or replacement of the LED light assembly 3 is needed, the bolts used to lock the LED light board 32 can be loosened beforehand, allowing the heat sink 41 to slide towards the lamp cap 1, thanks to its structural design.This arrangement allows the heat sink 411 to protrude within the groove 13, supporting the LED assembly 3 and keeping it away from the corresponding mounting surface of the lamp cap 1 and the grease-like thermal grease applied thereon. This facilitates the removal of the LED assembly 3 from within the lamp cap 1. Furthermore, the arrangement of several heat sinks 411, compared to traditional methods due to the limited internal space of the lamp cap 1, effectively reduces the probability of damage to the LED assembly 3 caused by tilting or collision during disassembly. It also reduces unnecessary contamination of the thermal grease during operation, facilitating subsequent replenishment of thermal grease and replacement of the LED assembly 3, thus improving structural flexibility and applicability.

[0025] A compression spring 112 is also fitted onto the connecting rod 11. The compression spring 112 is located on the side away from the lamp cap 1, and its corresponding two ends abut against the heat sink 41 and the locking member 111, respectively. The compression spring 112 can be added and fitted onto the connecting rod 11 according to the usage requirements. Multiple sets of locking members 111 are set on the connecting rod 11 on both sides of the protrusion 412. The position of the protrusion 412 on the heat sink 41 is set such that when the corresponding end face of the heat sink 411 is flush with the mounting end face of the LED light group 3 inside the lamp cap 1, there is a certain distance between the protrusion 412 and the corresponding end face of the lamp cap 1. The structural setting of the corresponding locking member 111 and the number of them at the corresponding distance must ensure that rotation is possible within the corresponding distance range of the connecting rod 11. Adjustment allows for the subsequent disassembly of the LED light assembly 3 and loosening of the corresponding bolts. The corresponding number of locking pieces 111 on the connecting rod 11, located between the protrusion 412 and the lamp cap 1, can be rotated appropriately. This allows the heat sink 41 to slide synchronously in a direction close to the lamp cap 1 under the action of the compression spring 112. Compared to manually pressing the heat sink 41 to separate the LED light assembly 3 from the corresponding mounting surface inside the lamp cap 1, this further reduces the probability of damage to the LED light assembly 3. While allowing the heat sink 41 to be disassembled, the locking pieces 111 also adjust the elastic force of the compression spring 112, ensuring the positional stability of the heat sink 41 on the connecting rod 11 and meeting different disassembly and assembly requirements.

[0026] A stop block 5 is provided between the lamp cap 1 and the heat sink 41. The stop block 5 is detachably installed on the heat sink 41. Specifically, the stop block 5 can be detachably connected by inserting a plug 50 into a slot 414 opened on the corresponding wall surface of the protrusions 412 at both ends of the heat sink 41. The slots 414 can be opened in two sets on the walls on both sides of the protrusions 412. During connection, the stop block 5 can be placed between the corresponding wall surface of the protrusions 412 and the lamp cap 1. Combined with the position setting of the protrusions 412 and the thickness setting of the stop block 5, the corresponding end face of the heat sink 411 is just flush with the mounting end face of the LED light group 3 inside the lamp cap 1. After the LED light group 3 needs to be disassembled and the corresponding bolts are loosened, the light group 3 can be moved away from the lamp cap 1. The sliding heat sink 41 allows the stop block 5 on the protrusion 412 to be pulled out and separated from the slot 414. After removal, the stop block 5 can be inserted into the slot 414 at the other end of the protrusion 412 for connection and fixation, thereby effectively reducing the probability of the stop block 5 being lost after removal. Subsequently, the protrusion 412 is not blocked by the stop block 5, and the heat sink 41 slides in the direction close to the lamp cap 1 under the action of the compression spring 112 until the protrusion 412 is in a state of contact with the corresponding end face of the lamp cap 1. Combined with the above sliding process, the corresponding end face of the heat sink 411 can slide out in the slide groove 13 to separate the LED lamp group 3 from the mounting end face of the lamp cap 1. This further improves the diversity and flexibility of the operation method for disassembling the LED lamp group 3.

[0027] The heat dissipation assembly 4 also includes a cooling fan 42 disposed on one side of the heat sink 411. The cooling fan 42 is detachably mounted on the connecting rod 11 via a connecting bracket 420 disposed thereon. Specifically, it can be combined with... Figure 3 and Figure 4 As shown, the connecting bracket 420 can slide through the connecting rod 11 by connecting the fourth slots 421 at both ends, so as to realize the detachable connection of the cooling fan 42 to the lamp cap 1. At the same time, it can be combined with multiple sets of locking pieces 111 to adjust and lock the position of the connecting bracket 420 on the connecting rod 11 and the cooling fan 42 on one side of several sets of heat sinks 411 placed on the heat sink 41. The connection line of the cooling fan 42 can be connected through multiple sets of second slots 21 on the corresponding wall of the lamp cover 2 according to the set power of the LED lamp group 3 and the corresponding brightness and darkness duration under the usage requirements. This allows for the selective use of a separate switch for connecting the external power supply according to the required brightness and darkness duration under different usage environments, or it can be combined with the PCB and other circuit boards 20 installed in the lamp cover 2 to enable the combined start and stop of the switch. Thus, combined with the addition of the cooling fan 42 structure, the effect of the heat dissipation component 4 and the heat dissipation effect of the LED lamp group 3 can be further improved, meeting the usage requirements under different usage environments.

[0028] A flared outer cover 422 can be detachably installed on the connecting frame 420 located around the cooling fan 42. The outer cover 422 has several sets of through holes 423. The outer cover 422 can be detachably installed on the connecting frame 420 by bolts. With the several sets of through holes 423, it facilitates air exhaust and can also provide a certain air gathering and protection effect for the cooling fan 42, improving the performance and heat dissipation stability of the cooling fan 42. It can also appropriately reduce the damage to the lamp cover 2 when it is hit by a collision under the support of the outer cover 422, and appropriately improve the structural stability of the lamp cover 2. In addition, with the protrusion 120 of appropriate length extending along the slot 12 on the corresponding end face of the lamp cap 1, it is convenient to run and arrange the LED lamp group 3 inside, while reducing the probability of the connecting wires getting tangled and knotted inside the lamp cover 2 due to the addition of the cooling fan 42, or even causing damage to the cooling fan 42, thus improving the performance stability of this LED lamp with heat dissipation structure.

[0029] The heat sink 411 has a groove 415 inside, and a connecting part 416 is also provided on the groove 415. The connecting part 416 is configured as either a protrusion 417 along both sides of the groove 415 for connecting two adjacent sets of heat sinks 411, or a protrusion 418 inside the groove 415 for connecting two adjacent sets of heat sinks 411. The protrusion 418 is diamond-shaped. Specifically, it is to further improve the heat dissipation effect of the cooling fan 42 and the heat sink 41 in the heat dissipation assembly 4. The groove 415 can be opened inside the heat sink 411, and the connecting part 416 can be configured along the groove 415 as follows: Figure 6 The convex plate 417 structure shown or Figure 7 The diamond-shaped protrusion 418 structure shown is specifically configured when the connecting part 416 is set as follows: Figure 6 The heat sink 41, formed by the convex plate 417 structure shown, ensures the stable connection of the overall structure of the heat sink 41. Combined with the opening of the groove 415 on the heat sink 411, the resulting cavity can achieve a certain airflow concentration effect. When the connecting part 416 is set as... Figure 7 The heat sink 41 formed by the protrusion 418 structure shown in the figure ensures the overall structural connection of the heat sink 41. At the same time, the rhomboid structure of the protrusion 418 can work with the groove 415 to achieve a certain directional airflow effect. The heat sink 41 with the corresponding structure formed by the connection part 416 can be selected and used according to the actual heat dissipation effect and heat dissipation requirements, so as to meet the different heat dissipation requirements of the LED light group 3 and improve the flexibility and applicability of use.

[0030] The lamp cover 2 is also provided with several sets of spaced through grooves 22, and a cover plate 23 can be detachably installed on the lamp cover 2 located around the through grooves 22. The cover plate 23 has an opening 230, from which... Figure 1 , Figure 2 as well as Figure 5 As can be seen, the opening and corresponding arrangement of several sets of through slots 22 on the lamp cover 2 can further improve the ventilation effect inside the lamp cover 2 and ensure the working stability of the heat dissipation component 4. At the same time, according to the actual use environment, the cover plate 23 can be connected and covered on the lamp cover 2 outside the through slots 22 with bolts. Furthermore, the openings 230 on the cover plate 23 can be flexibly opened and adjusted according to the actual installation and orientation of this LED light with heat dissipation structure. This ensures the ventilation effect while appropriately reducing the phenomenon of dust, rainwater and other media entering the lamp cover 2 through the through slots 22 under the cover plate 23, thereby improving the applicability and stability of this LED light with heat dissipation structure in different environments.

[0031] The lamp cap 1 located around the LED light group 3 is also detachably equipped with a diffuser cup 6, a transparent sheet 7, and a fixing ring 8, which are specifically combined with... Figure 2 As shown, the diffuser cup 6 can be embedded in the lamp cap 1 and abut against the LED lamp assembly 3. The transparent sheet 7 can be placed on the diffuser cup 6 to cover it. The fixing ring 8 can abut against the transparent sheet 7 and the diffuser cup 6 inside the lamp cap 1 and connect and fix them to the lamp cap 1 with bolts. This further improves the detachability and disassembly flexibility of the overall structure of this LED lamp with heat dissipation structure, making it convenient for daily maintenance cleaning and subsequent maintenance replacement of corresponding parts.
