This device usually includes a communication module and a driver. The communication module receives adjustment signals and transmits them to the MCU module within the driver for dimming operations. However, in existing lighting control devices, the communication module and driver are integrated, which introduces electromagnetic interference, temperature variations, and electrical isolation issues for the communication module. Furthermore, failure of any one module affects the entire device, resulting in low reliability. Directly externalizing the communication module and connecting it via a wiring port on the side wall of the driver would also interfere with the internal potting compound within the driver.

[0008] Optionally, the connecting portion on the driver is fixedly connected to the carrier by threaded fasteners.

[0009] Optionally, the carrier has a mounting surface; the mounting surface is configured such that after the driver is mounted on the carrier, the communicator can slide on the mounting surface to insert the first plug-in terminal into the first plug-in port.

[0010] Optionally, during the process of inserting the first connector into the first connector port, the direction of movement of the communicator is the first direction;

[0011] The carrier is provided with a guide portion, the guide portion having a guide surface arranged along the first direction, and one end face of the communicator abuts against the guide surface.

[0019] Because of the adoption of the above technical solution, this utility model has at least the following advantages and positive effects compared with the prior art:

[0020] (1) The lighting control device installed inside the lamp provided by this utility model has a communication module with the communicator external to the driver, which effectively isolates the high-temperature environment and potential electromagnetic radiation sources generated during the operation of the driver, thereby significantly reducing the temperature impact and electromagnetic interference on the communication module. This design ensures the stability and reliability of the communication module, reduces communication failures caused by environmental factors, and improves communication quality and operating efficiency.

[0021] (2) When potting glue into the cavity inside the driver, the glue is poured vertically. The lighting control device installed in the lamp provided by this utility model has a first plug-in port / first plug-in terminal that is electrically connected to the driver module on the connecting part. When potting glue into the cavity, the connecting part is located above the cavity. Therefore, there will be no glue leakage when potting glue into the cavity.

[0022] (3) When fixing the driver, it is generally fixed by threaded fasteners. If the threaded fasteners are directly fixed on the driver, it is easy to cause problems such as glue leakage. However, the problem can be solved by fixing the threaded fasteners on the connection part. That is, the setting of the connection part also solves the problem of fixing and installing the driver.

[0023] (4) The connecting part is not only provided with a first plug-in port / first plug-in terminal that is electrically connected to the communication module, but also with a second plug-in port / second plug-in terminal that is electrically connected to other external components; by integrating all the plug-in ports / plug-in terminals used to realize the electrical connection between the drive module and the external components on the connecting part, it can effectively avoid affecting the potting.

In this document, "one" not only means "only one," but can also mean "more than one."

[0035] Example 1

[0036] See Figures 1 to 4 This embodiment provides a lighting control device installed inside a lamp, including a driver 1 and a communicator 2. The communicator 2 contains a communication module. The driver 1 has a receiving cavity, and its driving module (i.e., MCU and AC / DC modules, etc.) is located within the receiving cavity. The driver 1 has a connecting part 4 located outside the receiving cavity, and the connecting part 4 is configured to be positioned above the receiving cavity when the receiving cavity is potted. Either the communicator 2 or the driver 1 has a first plug-in terminal, and the other has a first plug-in port. The communication module is electrically connected to the first plug-in terminal 7 / first plug-in port on the communicator 2, and the driving module is electrically connected to the first plug-in port 5 / first plug-in terminal on the driver 1. The first plug-in terminal 7 and the first plug-in port 5 are detachably connected.

[0037] The communication module is external to the driver 1, effectively isolating it from the high-temperature environment and potential electromagnetic radiation sources generated during driver 1 operation, thus significantly reducing the temperature impact and electromagnetic interference on the communication module. This design ensures the stability and reliability of the communication module, reduces communication failures caused by environmental factors, and improves communication quality and operating efficiency. Meanwhile, the first plug-in port 5 / first plug-in terminal electrically connected to the driver module is located on the connecting part 4. Since the connecting part 4 is positioned above the receiving cavity during potting, no glue leakage occurs when potting the receiving cavity.

[0038] In this embodiment, the connecting part 4 protrudes from one end of the driver; the communicator 2 is provided with a first plug terminal 7, the communication module is electrically connected to the first plug terminal 7, the connecting part 4 is provided with a first plug port 5, and the driver module is electrically connected to the first plug port 5.

[0039] Preferably, the connecting part 4 is further provided with at least one second plug-in port 6 and / or at least one second plug-in terminal, the second plug-in port 6 and the second plug-in terminal being electrically connected to the drive module, and the second plug-in port 6 and the second plug-in terminal being used for electrical connection with external components; wherein, the external components do not include a communication module. Specifically, in this embodiment, the connecting part 4 is provided with a second plug-in port 6, and the second plug-in port 6 is located on the top surface of the connecting part 4; the first plug-in port 5 is located on the side of the connecting part 4. By integrating all the plug-in ports (including the first plug-in port 5 and the second plug-in port 6) used to realize the electrical connection between the drive module and the external components on the connecting part 4, it is possible to effectively avoid affecting the potting process.

[0040] The lighting control device installed inside the lamp in this embodiment also includes a carrier 3. The driver 1 and the communicator 2 are both installed on the carrier 3, and at least one of the driver 1 and the communicator 2 is detachably connected to the carrier 3. The driver 1 and the communicator 2 are fixed by fixing them to the carrier 3.

[0041] Specifically, to secure the driver 1 to the carrier 3, the portion of the connecting part 4 without a plug-in port can be fixedly connected to the carrier 3 using threaded fasteners. Therefore, the connecting part 4 not only serves to provide a plug-in port but also solves the installation problem of the driver 1. Directly fixing the threaded fasteners to the driver 1 could easily lead to problems such as glue leakage, while fixing the threaded fasteners to the connecting part 4 solves this problem.

[0042] Furthermore, to make the fixed connection between the driver 1 and the carrier 3 more stable, a fixing plate can be protruded from the other end of the driver 1 where the connecting part 4 is not provided, and the fixing plate can be fixedly connected to the carrier 3 using threaded fasteners. The threaded fasteners used to fix the driver 1 can be screws or the like.

[0043] After the driver 1 is fixedly mounted on the carrier 3, the first plug-in terminal 7 on the communicator 2 is plugged into the first plug-in port 5 on the connecting part 4, and then the communicator 2 is fixedly mounted on the carrier 3. Alternatively, threaded fasteners such as screws can be used to achieve the fixed connection between the communicator 2 and the carrier 3.

[0044] The driver 1 and the communicator 2 are fixedly mounted on the carrier 3, and the carrier 3 is then fixedly mounted inside the electrical cavity 15 of the lamp.

[0045] Example 2

[0046] See Figures 5 to 8 This embodiment provides a lighting control device installed in a lamp based on embodiment 1. The difference between this embodiment and embodiment 1 is that the communication device 2 and the carrier 3 are fixed in different ways.

[0047] The carrier 3 has a mounting surface 13; the mounting surface 13 is configured such that after the driver 1 is mounted on the carrier 3, the communicator 2 can slide on the mounting surface 13 to insert the first plug-in terminal 7 into the first plug-in port 5. In this embodiment, the conventional installation method for the lighting control device installed in the lamp is as follows: first, the driver 1 is fixedly mounted on the carrier 3; then, the communicator 2 is placed on the mounting surface 13 of the carrier 3; the first plug-in terminal 7 on the communicator 2 is aligned with the first plug-in port 5 on the connecting part 4; then, the communicator 2 is pushed to slide on the mounting surface 13 until the first plug-in terminal 7 is inserted into the first plug-in port 5 and fully engaged; then, the communicator 2 is fixed to the carrier 3. Unless otherwise specified, the installation method of the lighting control device mentioned below refers to the above-described "conventional installation method".

[0048] Of course, the above installation method is only one feasible installation method of the lighting control device in this embodiment, and is not a limitation on the lighting control device in this embodiment. Users can also use other installation sequences when installing the lighting control device, such as first plugging the first plug terminal 7 on the communicator 2 into the first plug port 5 on the connecting part 4, and then fixing the communicator 2 and driver 1 connected together onto the carrier 3, etc.

[0049] For ease of description, the direction of movement of the first plug-in terminal 7 during the process of inserting the first plug-in port 5 is defined as the first direction. Both the first and second directions are parallel to the mounting platform, the first direction is perpendicular to the second direction, and the third direction is perpendicular to the mounting platform. The process of pushing the communicator 2 to slide on the mounting platform so that the first plug-in terminal 7 is plugged into the first plug-in port 5 is called the sliding installation process of the communicator 2.

[0050] A guide portion can be provided on the carrier 3. The guide portion has a guide surface arranged along a first direction, and one end face of the communicator 2 abuts against the guide surface. The guide surface is provided so that during the sliding installation of the communicator 2, as long as the communicator 2 is placed on the mounting plane 13 and abuts against the guide surface, and then the communicator 2 is pushed towards the driver 1, the communicator 2 slides against the mounting plane 13 and the guide surface respectively. Under the constraint of the mounting plane 13 and the guide surface, the first plug-in terminal 7 can be smoothly inserted into the first plug-in port 5. The whole process is convenient and quick.

[0051] Specifically, the guide surface can be a guide plate 8 protruding from the mounting plane 13. More specifically, the carrier 3 can be a plate (referred to as a carrier plate), with a portion of the carrier plate bent in a third direction, and the end of the bent portion can form the guide plate 8.

[0052] A limiting part can be provided on the carrier 3. The limiting part has a limiting surface that is set toward the mounting plane 13 and parallel to the mounting plane 13. The limiting part is used to restrict the degree of freedom of the communicator in the direction perpendicular to the mounting plane (that is, the third direction).

[0053] Specifically, the limiting part can be a limiting plate 10 parallel to the mounting plane 13, and the limiting surface is the surface of the limiting plate 10 facing the mounting plane 13; the communicator 2 is provided with a limiting groove that matches the shape of the limiting plate 10, and the limiting plate 10 extends into the limiting groove. When the limiting part is the limiting plate 10, the cooperation between the limiting plate 10 and the limiting groove alone can restrict the degree of freedom of the communicator 2 in the third direction.

[0054] The limiting plate 10 is connected to the carrier 3, meaning the limiting plate 10 can be fixedly connected to the carrier 3. More specifically, a portion of the carrier plate (here, the portion of the carrier plate arranged along the first direction) is first bent in a third direction and then bent in a second direction, with the end of the bent portion forming the limiting plate 10. The portion formed when bending in the third direction can be called a connecting plate 11. The connecting plate 11 is connected to the carrier plate and the limiting plate 10 at both ends in the third direction, and the connection point (also the bending point) can be an arc-shaped transition. Preferably, the communicator 2 has connecting plates 11 at both ends in the second direction (the connecting plate 11 does not exist alone; the connecting plate 11 is necessarily connected to the limiting plate 10).

[0055] Preferably, the limiting groove is provided along the first direction, and the end of the limiting groove facing the driver 1 extends to the outer surface of the communicator 2. During the sliding installation of the communicator 2, when the different surfaces of the communicator 2 abut against the mounting plane 13 and the guide surface and slide on them respectively, the limiting plate 10 can smoothly slide into the limiting groove and slide within the limiting groove.

[0056] The mounting plane 13 has a first hole 14 (the first hole 14 is actually set on the carrier 3), and the communicator 2 has a second hole. The pin 12 passes through the first hole 14 and the second hole in sequence. During the sliding installation of the communicator 2, the communicator 2 is first placed on the mounting plane 13, and the two outer surfaces of the communicator 2 abut against the mounting plane 13 and the guide surface respectively, pushing the communicator 2 to move towards the driver 1 (during the movement, the two outer surfaces of the communicator 2 slide on the mounting plane 13 and the guide surface respectively); during the movement, the limiting plate 10 connected to the carrier 3 is smoothly inserted into the limiting groove on the communicator 2 and slides in the limiting groove; after the first plug-in terminal 7 on the communicator 2 is inserted into the first plug-in port 5 on the connecting part 4 and plugged in, the communicator stops moving, and then the pin 12 is inserted into the second hole on the communicator 2 and the first hole 14 on the carrier 3. In this way, the electrical connection between the communication module in the communicator 2 and the driving module in the driver 1 is completed, and the communicator 2 is installed and fixed on the carrier 3.

[0057] The lighting control device installed inside the lamp provided in this embodiment has a communicator 2 with a communication module external to the driver 1, effectively isolating it from the high-temperature environment and potential electromagnetic radiation sources generated during the operation of the driver 1, thereby significantly reducing the temperature impact and electromagnetic interference on the communication module. This design ensures the stability and reliability of the communication module, reduces communication failures caused by environmental factors, and improves communication quality and operating efficiency. Furthermore, because the connecting part 4 of the first plug-in port 5 on the driver 1 protrudes from one end of the driver 1 rather than being directly located beside the internal cavity of the driver 1, there will be no leakage of adhesive when filling the cavity with glue.

[0058] Furthermore, the connecting part 4 not only serves to set the first plug-in port 5 and the second plug-in port 6, but also to fix the driver 1. Generally, the driver 1 is fixed by threaded fasteners. If the threaded fasteners are directly fixed on the driver 1, it is easy to cause problems such as glue leakage. However, by fixing the threaded fasteners to the connecting part 4, this problem can be solved. That is, the connecting part 4, which protrudes from one end of the driver 1, also solves the problem of fixing and installing the driver 1.

[0059] The connecting part 4 is not only provided with a first plug-in port 5 for electrical connection with the communication module, but also with a second plug-in port 6 for electrical connection with other external components. By integrating all the plug-in ports (including the first plug-in port 5 and the second plug-in port 6) for electrical connection between the drive module and external components on the connecting part 4, it is possible to effectively avoid affecting the potting process.

[0060] The lighting control device installed inside the lamp provided in this embodiment guides the insertion of the communicator 2 by setting a guide surface, and restricts the degree of freedom of the communicator 2 in the second direction by cooperating with the guide surface and the pin 12 (and the first hole 14 and the second hole that cooperate with the pin 12). The cooperation between the limiting plate 10 connected to the carrier 3 and the limiting groove on the communicator 2 can restrict the degree of freedom of the communicator 2 in the third direction. Thereafter, by inserting the pin 12 into the second hole on the communicator 2 and the first hole 14 on the carrier 3, the degree of freedom of the communicator 2 in the first direction can be restricted. In practice, even without the guide plate 8, limit plate 10, pin 12, etc., the first plug-in terminal 7 on the communicator 2 and the first plug-in port 5 on the connecting part 4 can limit the degrees of freedom of the communicator 2 in the first direction, the second direction, and the third direction. However, considering that the connection between the first plug-in terminal 7 and the first plug-in port 5 is mainly used for the electrical connection between the communication module and the drive module, and the structural strength itself is not high, the guide plate 8, limit plate 10, pin 12 and other structures are further set to restrict the degrees of freedom of the driver 1.

[0061] The lighting control device installed inside the lamp provided in this embodiment allows for easy and quick connection of the communication module and the drive module by simply placing the communicator 2 on the mounting plane 13 and abutting it against the guide surface when inserting the first connector 7 into the first connector port 5. This aligns the first connector 7 with the first connector port 5 and the limiting groove with the limiting plate 10. Then, simply push the communicator 2 towards the driver 1 to achieve electrical connection between the communication module and the drive module. Furthermore, afterward, simply insert the pin 12 into the second hole on the communicator 2 and the first hole 14 on the carrier 3 to fix the communicator 2 onto the carrier 3, which is also convenient and quick.

Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
