Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a lamp. Background Technology

[0002] In the field of modern lighting, the application scenarios for luminaires are becoming increasingly diverse, covering a variety of complex indoor and outdoor environments. Whether it is urban outdoor lighting, industrial plant lighting, or indoor environments such as humid bathrooms and kitchens, higher demands are placed on the performance of luminaires. In these environments, luminaires not only need to emit light stably for a long time, but also need to adapt to different conditions such as temperature, humidity, dust, and moisture.

[0003] However, most lighting fixtures on the market today cannot simultaneously meet the requirements of efficient heat dissipation and good sealing. This results in frequent problems such as severe light decay and circuit failures due to poor heat dissipation when used in complex environments, as well as short circuits and component corrosion caused by poor sealing. These issues greatly affect the user experience and application range of the lighting fixtures. Utility Model Content

[0045] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0046] See Figure 1 and Figure 5 This utility model discloses a lamp, which includes a mounting housing 10, a circuit board assembly 20, and a lamp assembly 30. (See reference...) Figure 4 and Figure 5 The mounting housing 10 includes a heat dissipation cavity 11, a first mounting cavity 12, and a second mounting cavity 13. A heat dissipation assembly is housed within the heat dissipation cavity 11, and this assembly dissipates heat from the first mounting cavity 12 and the second mounting cavity 13. The first mounting cavity 12 is sealed using a sealing assembly. (See again...) Figure 5The circuit board assembly 20 is installed in the first mounting cavity 12, and the circuit board assembly 20 is provided with a first electrical connector 21; the lamp assembly 30 is installed in the second mounting cavity 13 and is sealed to the second mounting cavity 13, and the lamp assembly 30 is provided with a second electrical connector 31. The second electrical connector 31 is electrically connected to the first electrical connector 21.

[0047] Based on this structure, when assembling the lamp of this invention, the circuit board assembly 20 can be installed in the first mounting cavity 12, followed by the lamp assembly 30 being installed in the second mounting cavity 13. Then, the second electrical connector 31 of the lamp assembly 30 is electrically connected to the first electrical connector 21 of the circuit board assembly 20. The first mounting cavity 12 is then sealed using a sealing assembly, similarly ensuring a sealed fit between the lamp assembly 30 and the second mounting cavity 13.

[0048] After installation, connect the power supply, and the lamp can be used normally. During use, if a malfunction occurs, since the circuit board assembly 20 and the lamp assembly 30 are installed relatively independently in different mounting cavities, it is relatively convenient to disassemble, inspect, and repair individual components without worrying about the external environment affecting the undisassembled components.

[0049] The heat dissipation components within the heat dissipation cavity 11 can simultaneously dissipate heat from both the first mounting cavity 12 and the second mounting cavity 13. During lamp operation, the heat generated by the circuit board assembly 20 and the lamp assembly 30 can be transferred to the heat dissipation cavity 11 through the structure of the mounting housing 10 or heat transfer components. The heat is then dissipated quickly to the external environment using the heat dissipation components and channels within the cavity 11. This efficient heat dissipation structure reduces the risk of component performance degradation and shortened lifespan due to heat accumulation, ensuring stable operation of the lamp over extended periods.

[0050] It should be noted that, since the heat dissipation cavity 11 needs to be connected to the external environment to achieve heat dissipation, the heat dissipation cavity 11 is not sealed. Rainwater and dust from the outside may enter the heat dissipation cavity 11 through the heat dissipation groove 151 on the mounting shell 10 that connects the heat dissipation cavity 11 to the external environment.

[0051] This invention integrates the heat dissipation cavity 11, the first mounting cavity 12, and the second mounting cavity 13 into a single housing. The first mounting cavity 12 is sealed using a sealing assembly, effectively isolating the circuit board assembly 20 from external dust, moisture, and other impurities. Similarly, the lamp assembly 30 is sealed to the second mounting cavity 13, preventing external environmental influences. This independent sealing design allows the lamp to utilize the heat dissipation cavity 11 for heat dissipation while preventing rainwater from entering the first and second mounting cavities 12 and 13. This prevents short circuits caused by dust intrusion or component corrosion due to moisture intrusion, significantly improving the reliability and stability of the lamp.

[0052] Furthermore, the first electrical connector 21 and the second electrical connector 31 can be existing pin header connectors and female header connectors. By mounting the pin header connector and female header connector onto the circuit board assembly 20 and the lamp assembly 30 respectively, and then electrically connecting the pin header and female header via a wire harness 70, with suitable terminals crimped or soldered to both ends of the wire harness 70, these terminals can be adapted to connect with the pin header and female header. Thus, the electrical signals or energy generated by the circuit board assembly 20 can be transmitted to the lamp assembly 30, driving the lamp to emit light and ensuring the lamp functions normally.

[0053] As an optional implementation, the sealing assembly includes a first seal 40, see [reference]. Figure 4 and Figure 6 The mounting housing 10 is provided with a partition 14, which divides the cavity enclosed by the mounting housing 10 into a heat dissipation cavity 11 and a first mounting cavity 12. The partition 14 has a mounting opening 141, which connects the heat dissipation cavity 11 and the first mounting cavity 12. (See reference...) Figure 5 The first electrical connector 21 is installed in the mounting port 141, and the first sealing member 40 is disposed between the outer periphery of the first electrical connector 21 and the inner wall of the mounting port 141.

[0054] Based on this structure, during assembly, the circuit board assembly 20 is installed into the first mounting cavity 12, and the first electrical connector 21 on the circuit board assembly 20 is aligned with the mounting port 141 on the partition 14. Then, the first electrical connector 21 is inserted into the mounting port 141, and the first seal 40 is installed between the outer periphery of the first electrical connector 21 and the inner wall of the mounting port 141.

[0055] The first sealing element 40 can be a sealing ring, specifically a rubber ring or a silicone ring. The first electrical connector 21 and the mounting port 141 are pressed together to ensure that the first sealing element 40 fits tightly against the gap between the first electrical connector 21 and the mounting port 141, thus ensuring the sealing of the first mounting cavity 12 and preventing dust, moisture and other impurities in the heat dissipation cavity 11 from entering the first mounting cavity 12 through the mounting port 141, effectively protecting the circuit board assembly 20.

[0056] As an alternative implementation method, please refer again. Figure 6 The partition 14 is provided with a heat dissipation vent 142. Specifically, the heat dissipation vent 142 connects the heat dissipation cavity 11 and the first mounting cavity 12. (See reference...) Figure 5 The heat dissipation vent 142 is provided with a heat-conducting element 50, and the heat dissipation assembly includes a first heat dissipation element 51. The first heat dissipation element 51 abuts against the partition plate 14 and covers the heat dissipation vent 142; the first heat dissipation element 51 is connected to one side of the heat-conducting element 50, and the other side of the heat-conducting element 50 is connected to the circuit board assembly 20.

[0057] In addition, the first heat sink 51 is provided with an annular mounting groove 511 on the side facing the partition 14, and the sealing assembly also includes a second seal 41, which is installed in the annular mounting groove 511 and seals the gap between the partition 14 and the first heat sink 51.

[0058] Based on this structure, when the circuit board assembly 20 is in operation, it generates heat and transfers it directly to the heat conductor 50 through its surface. The heat conductor 50 then transfers the heat to the first heat sink 51 on the other side, and dissipates the heat to the external environment through the heat dissipation cavity 11.

[0059] The heat-conducting component 50 can be thermally conductive silicone, which transfers the heat from the circuit board assembly 20 to the first heat sink 51 on the other side. The first heat sink 51 can be a metal sheet or a heat pipe, which rapidly absorbs heat through the high thermal conductivity of the metal material, thereby rapidly cooling the heat-conducting component 50 and dissipating heat from the circuit board assembly 20.

[0060] Alternatively, the second sealing element 41 can be a rubber ring, silicone gasket, etc. During the installation of the second heat sink 52, the second sealing element 41 is pressed against the partition plate 14 by the annular mounting groove 511 on the second heat sink 52, filling the tiny gap between them, thereby sealing the heat dissipation port 142 and forming a physical seal between the heat dissipation cavity 11 and the first mounting cavity 12. Furthermore, when the thermally conductive element 50 is made of thermally conductive silicone, its elastic deformation capability allows for a better seal of the heat dissipation port 142.

[0061] Thus, the circuit board assembly 20 in the first mounting cavity 12 can transfer heat to the heat sink in the heat sink 11 through the heat conduction element 50 in the heat sink 142 on the partition 14, thereby achieving heat dissipation. At the same time, the second sealing element 41 can also seal the first mounting cavity 12 and the heat sink 11, preventing rainwater in the heat sink 11 from entering the first mounting cavity 12 through the heat sink 142, thus achieving the dual functions of efficient heat dissipation and good sealing.

[0062] As an optional implementation, the sealing assembly includes a third seal 42. See also... Figure 3 The mounting housing 10 includes a main housing 15 and an end cap 16, the end cap 16 being detachably mounted to one end of the main housing 15, see reference. Figure 5 The third sealing element 42 is installed at the connection between the end cover 16 and the main housing 15. The first mounting cavity 12 is formed between one side of the partition 14 and the end cover 16, and the other side of the partition 14 and the main housing 15 form a heat dissipation cavity 11.

[0063] Based on this structure, during assembly, the end cap 16 can be first separated from the main housing 15, and then the circuit board assembly 20 can be installed in the first mounting cavity 12, with the first electrical connector 21 on the circuit board assembly 20 installed in the mounting port 141 on the partition 14. Then, the third seal 42 is installed on the end of the main housing 15, and the end cap 16 is pressed onto the third seal 42 and connected to the main housing 15.

[0064] The main housing 15 has an annular groove at its end, and the third sealing element 42 can be a rubber, silicone, or metal sealing ring, which is embedded in the annular groove. The end cap 16 can be connected to the main housing 15 by screws, clips, or other means, and during the connection process, it squeezes the third sealing element 42 to seal the connection between the main housing 15 and the end cap 16.

[0065] Therefore, since the mounting port 141 on the partition 14 is sealed to the first electrical connector 21 by the first sealing member 40, the heat dissipation port 142 on the partition 14 is sealed to the first heat dissipation member 51 by the second sealing member 41, and the end cover 16 is sealed to the main housing 15 by the third sealing member 42, the first mounting cavity 12 formed by the end cover 16, the partition 14 and the main housing 15 together forms a sealed space, ensuring that dust and moisture on the outside of the end cover 16 and inside the heat dissipation cavity 11 cannot enter the first mounting cavity 12.

[0066] As an optional implementation method, see [link / reference]. Figure 7The inner wall of the main housing 15 is provided with a waterproof protrusion 93. Specifically, the waterproof protrusion 93 includes a surrounding wall 931 and an end wall 932. The end wall 932 is spaced apart from the inner wall of the main housing 15, and one end of the end wall 932 is connected to the partition plate 14. One end of the surrounding wall 931 is connected to the main housing 15, and the other end of the surrounding wall 931 is connected to the end wall 932. The surrounding wall 931 and the partition plate 14 together surround the outer periphery of the end wall 932. At the same time, the end wall 932, the surrounding wall 931, the partition plate 14, and the main housing 15 together form a waterproof cavity 92. The partition plate 14 is provided with a through opening 143, and the waterproof cavity 92 extends through the through opening 143 to the first mounting cavity 12.

[0067] See Figure 6 The outer side wall of the main housing 15 is provided with a first connecting groove 153, and a connecting port 442 is provided in the first connecting groove 153. The connecting port 442 penetrates the side wall of the main housing 15 and communicates with the waterproof cavity 92. (See reference...) Figure 2 The luminaire includes an electrical connector 91 and a mounting plate 90. The electrical connector 91 is installed in the communication port 442, the mounting plate 90 is detachably installed in the first connection groove 153, and the electrical connector 91 is electrically connected to the circuit board assembly 20.

[0068] Based on this structure, during assembly, the electrical connector 91 can be installed at the connecting port 442. After the electrical connector 91 is installed, it can be electrically connected to the circuit board assembly 20 in the first mounting cavity 12 via a wire to ensure circuit continuity. The wire is run through the waterproof cavity 92. Then, the mounting plate 90 is installed into the first connecting groove 153 and is detachably fixed by screws, clips, etc.

[0069] The gap between the electrical connector 91 and the connecting port 442 can be sealed using auxiliary sealing materials such as sealing rings or sealant to prevent moisture from entering the waterproof cavity 92 and the first mounting cavity 12 through the connecting port 442. Simultaneously, after the mounting plate 90 is installed, it can protect the electrical connector 91 from damage by external impacts, and further enhance the sealing performance at the first connecting groove 153.

[0070] It should be noted that the electrical connector 91 can be a spring pin, metal contact, or other similar material as in the prior art. When pressed by an external power connector, it can enable circuit conduction and power transmission, thereby providing power to the circuit board assembly 20 in the first mounting cavity 12.

[0071] As an optional implementation method, see [link / reference]. Figure 5A control module 24 is housed within the first mounting cavity 12, and is electrically connected to the circuit board assembly 20. The control module 24 includes an adjusting shaft 241, and an adjusting assembly 60 is located outside the mounting housing 10. A connection port is provided on the end cover 16, and the adjusting shaft 241 extends from the connection port and is connected to the adjusting assembly 60 in a transmission manner. It should be noted that the control module 24 converts the mechanical rotation or position change of the adjusting shaft 241 into an electrical signal, and the circuit board assembly 20 receives the electrical signal and outputs a control signal.

[0072] More specifically, the sealing assembly also includes a fourth seal 43. See also Figure 10 The control module 24 is provided with a mounting surface 242, and the adjusting shaft 241 is provided on the mounting surface 242. A boss 161 is provided in the connection port, the mounting surface 242 abuts against the connection port, and the fourth sealing element 43 is provided between the mounting surface 242 and the side of the boss 161.

[0073] Based on this structure, during assembly, the control module 24 and the circuit board assembly 20 are first installed in the first mounting cavity 12, and the control module 24 and the circuit board assembly 20 are electrically connected via wires or other connection methods. Then, a fourth seal 43 is installed between the mounting surface 242 of the control module 24 and the side of the boss 161 in the connection port. Subsequently, the mounting surface 242 of the control module 24 is placed against the connection port, and the adjusting shaft 241 extends from the connection port to the outside of the mounting housing 10. Finally, an adjusting assembly 60 is installed outside the mounting housing 10, and the adjusting assembly 60 is connected to the adjusting shaft 241 extending from the connection port.

[0074] When using the lamp, the adjustment shaft 241 can be mechanically rotated or its position changed by operating the adjustment component 60 outside the mounting housing 10. The control module 24 converts this mechanical change of the adjustment shaft 241 into an electrical signal and transmits the electrical signal to the circuit board assembly 20. After receiving the electrical signal, the circuit board assembly 20 analyzes and processes it, and outputs corresponding control signals to realize the control of functions such as dimming, color adjustment, and switching on / off of the lamp.

[0075] Thus, the control module 24 converts the user's mechanical operations outside the mounting housing 10 into electrical signals via the adjustment shaft 241, enabling the lamp to have an intuitive and convenient control method. This setup eliminates the need for complex electronic touch panels or wireless control devices; users can adjust various functions of the lamp simply by rotating or tossing them, reducing the difficulty of operation.

[0076] See Figure 10 and Figure 11The adjustment assembly 60 specifically includes a button 61, an adjustment disc 62, and a washer 63. The button 61 is connected to the adjustment shaft 241, and under manual control, the button 61 can drive the adjustment shaft 241 to move or rotate axially. The adjustment disc 62 is sleeved on the outer periphery of the adjustment shaft 241, and the adjustment disc 62 and the adjustment shaft 241 are connected by a threaded structure. The washer 63 is disposed on the outer periphery of the adjustment shaft 241, and is located between the connection port and the adjustment disc 62.

[0077] In addition, the control module 24 can be an encoder, potentiometer, or other existing technology. The fourth seal 43 can be a rubber ring, silicone gasket, or other similar material. The fourth seal 43, located at the connection port, can effectively prevent external dust, moisture, and other impurities from entering the first mounting cavity 12 through the gap between the adjusting shaft 241 and the connection port, thus protecting the control module 24 and the circuit board assembly 20 from external environmental influences.

[0078] As an optional implementation, the mounting housing 10 also includes a mounting base 32, a pressure cap 17, and a protective housing 18. For details, please refer to [link to relevant documentation]. Figure 5 The mounting base 32 is installed at the end of the main housing 15 away from the end cover 16. The protective housing 18 is installed on one side of the mounting base 32 and abuts against the mounting base 32. The pressure cover 17 is detachably connected to the main housing 15 and surrounds the outer periphery of the protective housing 18 and is detachably connected to the protective housing 18. The mounting base 32 forms a second mounting cavity 13.

[0079] In addition, see Figure 8 The lamp assembly 30 includes an optical accessory 33 and a lamp plate 34. The lamp plate 34 is installed inside the main housing 15 and located at the bottom of the mounting base 32. The optical accessory 33 is installed in the second mounting cavity 13, and the lamp plate 34 is sealed to the second mounting cavity 13. The second electrical connector 31 is electrically connected to the lamp plate 34, and a heat dissipation cavity 11 is formed between the lamp plate 34 and the partition plate 14.

[0080] Based on this structure, during assembly, the lamp board 34 can be first installed inside the main housing 15, and the lamp board 34 is electrically connected to the circuit board assembly 20 in the first mounting cavity 12 via the second electrical connector 31 to ensure circuit continuity. Then, the mounting base 32 is installed at the end of the main housing 15, with its periphery sealingly fitted to the periphery of the lamp board 34. Next, the optical accessory 33 is placed into the second mounting cavity 13, and its position is adjusted to match the optical requirements of the lamp board 34 light source. Then, the protective shell 18 is placed against the mounting base 32, covering the opening of the second mounting cavity 13, and fixed from the outside by the pressure cap 17. The pressure cap 17 is connected to the main housing 15 with screws or a snap-fit ​​structure, and simultaneously snaps into the protective shell 18.

[0081] The mounting base 32 includes a flange 323 and a support ring 324. The flange 323 is arranged around the outer periphery of the support ring 324, and the outer periphery of the flange 323 abuts against the inner periphery of the main housing 15. The support ring 324 forms a second mounting cavity 13. (See reference...) Figure 1 and Figure 2 The mounting base 32 is detachably connected to the main housing 15 via the connecting assembly 80. Specifically, the connecting assembly 80 includes a sliding key 81, an elastic element 82, and a locking post 83. A locking hole is provided on the flange 323, and a sliding groove 152 is provided on the main housing 15. The sliding key 81 is slidably connected within the sliding groove 152. (See reference...) Figure 3 The locking pin 83 is connected to a connecting arm, the slide key 81 is connected to the connecting arm, and the elastic element 82 can be a spring, which is located at the bottom of the locking pin 83. The locking pin 83 can enter or exit the locking hole.

[0082] When the slide key 81 is pressed and slides within the sliding groove 152, it can drive the connecting arm and the locking pin 83 on the connecting arm to compress the elastic element 82 and exit the locking hole. At this time, the mounting base 32 can be removed from the main housing 15. When the slide key 81 is not subjected to external force, the locking pin 83 will pop out under the elastic action of the elastic element 82 and enter the locking hole. At this time, the mounting base 32 is limitedly connected to the main housing 15.

[0083] Additionally, the protective shell 18 can be made of transparent or semi-transparent material (such as PC or PMMA) to protect the optical accessory 33 while allowing light to pass through. The optical accessory 33 can be a lens, a reflector, etc., used to adjust the light angle, light spot shape, etc. In this invention, the optical accessory 33 is a combination of a lens and a reflector. The reflector is installed in the second mounting cavity 13, the lens is installed in the light outlet of the reflector, and the light-emitting element on the lamp plate 34 is installed in the light inlet of the reflector.

[0084] When the lamp panel 34 is powered on and emits light, the light is adjusted by the optical accessory 33 within the mounting base 32 to create the desired lighting effect. The protective shell 18 acts as a light-transmitting barrier, protecting the optical accessory 33 while allowing light to pass through. Its surface may be treated to prevent scratches and glare, thus improving the lighting quality.

[0085] It should be noted that the sealed fit between the lamp plate 34 and the mounting base 32 prevents moisture in the heat dissipation cavity 11 on the other side of the lamp plate 34 from entering the second mounting cavity 13 through the connection between the lamp plate 34 and the mounting base 32, thereby protecting the second electrical connector 31 and other electrical components such as the light-emitting element on the lamp plate 34. Simultaneously, the protective shell 18 covers the outside of the mounting base 32, preventing rainwater from the outside of the mounting shell 10 from entering the second mounting cavity 13.

[0086] As an optional implementation method, see [link / reference]. Figure 5A fifth seal 44 is provided between the mounting base 32 and the lamp plate 34, sealing the connection between the mounting base 32 and the lamp plate 34. (See reference...) Figure 9 The mounting base 32 has a second connecting groove 321 on one side, and the fifth sealing member 44 includes an interface sealing part 441, wherein the interface sealing part 441 is installed in the second connecting groove 321, and the second electrical connector 31 is installed in the interface sealing part 441.

[0087] Based on this structure, during assembly, the fifth seal 44 can be placed around the periphery of the lamp plate 34, and then the second electrical connector 31 on the lamp plate 34 is inserted into the interface sealing part 441 of the fifth seal 44, ensuring an interference fit between the terminal and the through hole of the seal. Then, the mounting base 32 is installed on the lamp plate 34, and the interface sealing part 441 is installed into the second connecting groove 321 on the mounting base 32.

[0088] The fifth sealing element 44 can be a rubber ring or a silicone gasket, etc., and its interface sealing part 441 is a silicone block or a fluororubber block, which is integrally formed on the fifth sealing element 44. The interface sealing part 441 is provided with a through groove 442, and the second electrical connector 31 is installed in the through groove 442.

[0089] Thus, the lamp board 34 and the mounting base 32 are sealed together by the fifth sealing element 44. The fifth sealing element 44 can prevent external moisture from seeping in from the connection between the mounting base 32 and the lamp board 34, and at the same time wrap the second electrical connector 31 to prevent water from entering the terminal interface.

[0090] In addition, the second connecting groove 321 is provided with a snap-fit ​​protrusion 322 on the side wall facing the interface sealing part 441, and the interface sealing part 441 is provided with a corresponding snap-fit ​​groove 443. When the interface sealing part 441 is pressed into the second connecting groove 321, the snap-fit ​​protrusion 322 is pressed into the snap-fit ​​groove 443, thereby further ensuring the sealing between the lamp board 34 and the mounting base 32.

[0091] As an optional implementation method, see [link / reference]. Figure 2 and Figure 3 The heat dissipation assembly also includes a second heat sink 52 and a third heat sink 53. The second heat sink 52 is connected to the lamp panel 34, and the third heat sink 53 is used to generate cooling airflow to dissipate heat from the second heat sink 52.

[0092] Based on this structure, when the lamp board 34 is working, the light-emitting element (such as an LED) and the second electrical connector 31 generate heat, which is conducted to the second heat sink 52 through the substrate of the lamp board 34. The second heat sink 52 quickly diffuses the heat to its own surface for heat dissipation, and at the same time, it dissipates heat rapidly under the action of the third heat sink 53.

[0093] The second heat sink 52 can be a heat sink fin made of metals such as aluminum or copper, which has a large heat dissipation area and can quickly exchange heat with the surrounding air. The third heat sink 53 can be a fan, which forms a directional airflow in the heat dissipation cavity 11. When the cooling airflow flows over the surface of the second heat sink 52, it dissipates the surface heat through convection heat exchange.

[0094] In addition, a plurality of heat dissipation slots 151 are provided on two opposite side walls of the main housing 15. One heat dissipation slot 151 is formed as an air inlet, and the other heat dissipation slot 151 is formed as an air outlet. When the third heat dissipation component 53 is started, it can draw in external cooling airflow through the air inlet, exchange heat with the second heat dissipation component 52 in the heat dissipation cavity 11, and then discharge the hot airflow through the air outlet.

[0095] It should be noted that since the lamp board 34 and the mounting base 32 are sealed by the fifth sealing element 44, the water vapor in the heat dissipation cavity 11 will not leak into the second mounting cavity 13, thus preventing water vapor and dust from entering with the airflow, affecting the optical performance or causing a short circuit.

[0096] As an optional implementation, the first electrical connector 21 and the second electrical connector 31 are connected by a wiring harness 70, and the outer side of the wiring harness 70 is provided with a waterproof sleeve.

[0097] Based on this structure, the first mounting cavity 12 and the second mounting cavity 13 are respectively located at both ends of the heat dissipation cavity 11. The first electrical connector 21 and the second electrical connector 31 span the heat dissipation cavity 11 and need to be connected by a wire harness 70. Specifically, the insulation of both ends of the wire harness 70 can be stripped, and the wires can be crimped to the metal terminals to form an interface that can electrically connect with the electrical connectors.

[0098] During connection, the first electrical connector 21 can be plugged into or soldered to the terminal at one end of the wiring harness 70, and the second electrical connector 31 can be fixed to the terminal at the other end of the wiring harness 70 by plugging or soldering. Thus, the circuit board assembly 20 transmits electrical signals or power to the wiring harness 70 through the first electrical connector 21, which is then conducted to the second electrical connector 31 via the wires of the wiring harness 70, and finally delivered to the lamp board 34.

[0099] The waterproof sleeve can be wrapped around the outside of the wire harness 70. Its material is usually silicone, rubber or heat shrink tubing. It is used to isolate the wire harness 70 from the external environment and prevent rainwater from penetrating along the wire harness 70 to the electrical connector interface.

[0100] Furthermore, in this invention, the circuit board assembly 20 includes a first circuit board 22 and a second circuit board 23, and the first circuit board 22 and the second circuit board 23 are electrically connected by wires. The control module 24 is mounted on the first circuit board 22, which supports electronic components and enables electrical connections. The second circuit board 23 can be a power board, which can convert, amplify, and control the electrical signals transmitted from the first circuit board 22, thereby controlling the lamp board 34.

[0101] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
