Description

Technical Field

[0001] This invention belongs to the field of lighting equipment technology, and specifically relates to a light-collecting lamp. Background Technology

[0002] The term "focusing light" is a new designation used in this study to describe the application of high-power LED lights. Many products actually exist on the market, such as high-powered flashlights, fishing lights, laser pointers, and photographic fill lights. The primary purpose is to meet the application needs in various scenarios regarding brightness, illumination range, lighting distance, and light color.

[0003] In use, existing lamp housings generate very high temperatures, and heat dissipation primarily relies on heat exchange between the housing surface and the external air. While halogen and metal halide lamps can withstand high operating temperatures, LEDs cannot operate at such conditions. Therefore, a heat dissipation problem must be solved for LED spotlights.

[0004] The existing heat dissipation methods generally include the following:

[0005] 1. Increase the contact area between the housing and the air to improve heat dissipation efficiency. For example, Chinese invention patent application number CN201910737524.1 discloses a self-heating LED spotlight, which enhances the heat dissipation effect by setting heat dissipation fins to increase the contact area with the outside air.

[0006] 2. Install a fan inside the lamp housing to accelerate air convection. For example, Chinese utility model patent application number CN201220230238.X discloses an LED spotlight that enhances heat dissipation by installing a fan inside a box-shaped heat dissipation device to circulate air between the inside and outside of the heat sink.

[0007] 3. Utilizing coolant to circulate within the housing to improve heat dissipation efficiency. For example, Chinese invention patent application number CN201910737536.4 discloses a convection liquid-cooled LED lamp that uses coolant to dissipate heat from the lamp.

[0008] Different heat dissipation methods are used to adapt to spotlights of different power levels to meet the lighting needs of users in different scenarios. Generally, during use, smaller spotlights use the first method of natural cooling, larger spotlights use the second method of air cooling, and high-power spotlights use the third method of liquid cooling.

[0009] To suit different usage scenarios, users need to purchase spotlights with different heat dissipation methods, or when the heat sink of a spotlight is damaged, the entire spotlight needs to be replaced. This results in high user costs and is likely to cause resource waste.

[0010] Therefore, designing a light-collecting lamp that can help users save on operating costs has become a technical problem that urgently needs to be solved by those skilled in the art.

[0011] In view of this, the present invention is proposed. Summary of the Invention

[0076] Example 1

[0077] like Figures 1 to 15 As shown in the embodiment of the present invention, a light-collecting lamp is introduced, which includes a front housing 31, a rear housing 32, and a heat sink 1 disposed between the front housing 31 and the rear housing 32.

[0078] In this embodiment, the front housing 31 and the rear housing 32 are detachably connected to the radiator 1, and the front housing 31 and the rear housing 32 are respectively provided with the same size connection structure between the front housing 31 and the front and rear ends of the radiator 1 of different models and / or using different heat dissipation methods.

[0079] Specifically, the connection structure includes interfaces at the front and rear ends of the radiator 1, and the ends of the front housing 31 and the rear housing 32 are respectively provided with plug-in parts adapted to the interfaces at the front and rear ends of the radiator 1. The plug-in parts of the front housing 31 and the rear housing 32 are at least partially plugged into the interfaces for assembly.

[0080] In this embodiment, the front and rear ends of the radiators 1 of different models and / or with different heat dissipation methods are provided with interfaces of a set specification. The ends of the front housing 31 and the rear housing 32 that are connected to the radiator 1 are provided with plug-in parts of a set specification. Thus, during use, the user can replace the radiator 1 individually according to the power of the spotlight. At the same time, during the use of the spotlight, the radiator 1 can be maintained and replaced individually, which helps to save the user's operating costs and reduce the waste of resources.

[0081] Preferably, in this embodiment, the front housing 31 and the rear housing 32 are respectively sealed to the radiator 1.

[0082] In some specific embodiments, the radiator 1 is cylindrical in shape, and the wall of the radiator 1 has a certain thickness in the radial direction.

[0083] The radiator 1 has one interface, and a sealing ring 5 is provided at the overlap between the insertion part of the front housing 31 and the rear housing 32 and the interface.

[0084] Alternatively, the interface includes a first interface and a second interface disposed on the outer periphery of the first interface, and the plug-in portion includes a first plug-in portion 33 and a second plug-in portion 34 corresponding to the first interface and the second interface respectively, and a sealing ring 5 is provided at the overlap of the first plug-in portion 33 with the first interface and / or the overlap of the second plug-in portion 34 with the second interface.

[0085] Preferably, a sealing ring 5 is provided at least between the first interface and the first plug-in portion 33.

[0086] Specifically, when designing the heat sink 1, at least one first interface is provided on the inner periphery of each end of the heat sink 1. The second interface can be selectively provided. In particular, the second interface can be selectively provided according to the heat dissipation method adopted by the heat sink 1.

[0087] like Figures 1 to 3 As shown in this embodiment, for a heat sink 1 with only a first interface at each end, the front housing 31 and the rear housing 32 adapted to it can be provided with only one first plug-in part 33, and a sealing ring 5 is provided between the first plug-in part 33 and the first interface.

[0088] The heat sink 1, which has only one first interface at each end, is only suitable for natural heat dissipation.

[0089] In this embodiment, the heat sink 1, which has only one first interface at each end, can be configured with multiple heat sinks of the same or different outer diameters for replacement or for users to purchase individually.

[0090] Preferably, in this embodiment, in order to enable the front housing 31 and the rear housing 32 to be adapted to liquid cooling and air cooling, for a heat sink 1 with only a first interface at each end, the front housing 31 and the rear housing 32 adapted to it can be provided with a first plug-in part 33 and a second plug-in part 34 of a set size at the end connected to the heat sink 1. Thus, the front housing 31 and the rear housing 32 can be adapted to a heat sink 1 with only a first interface or a heat sink 1 with both a first interface and a second interface.

[0091] When the front end and / or rear end of the radiator 1 are provided with a first interface and a second interface, a sealing ring 5 is provided at least between the first interface and the first plug-in portion 33.

[0092] Preferred, such as Figures 4 to 15 As shown, in this embodiment, the first interface and the second interface are staggered along the axial direction of the heat sink 1. The first interface and the second interface are connected by an extension wall 35 extending radially along the front housing 31 / rear housing 32, and the extension wall 35 abuts against the end of the heat sink 1. This arrangement facilitates the installation of the front housing 31 and the rear housing 32 on the heat sink 1 and ensures installation stability.

[0093] Preferably, the second interface extends outward relative to the first interface; the end of the second insertion part 34 is provided with an extension wall 35 extending radially toward the axis of the profile 100, and the extension wall 35 is provided with a first insertion part 33 extending into the first interface and engaging with the first interface.

[0094] Specifically, in this embodiment, the radiator 1 includes a profile 100, which includes a first cylindrical portion 101 and a second cylindrical portion 102. The outer diameter of the first cylindrical portion 101 is smaller than the inner diameter of the second cylindrical portion 102. The second cylindrical portion 102 is sleeved on the outer periphery of the first cylindrical portion 101 and is disposed around the first cylindrical portion 101. The outer wall of the first cylindrical portion 101 is spaced apart from the inner wall of the second cylindrical portion 102. A fin 103 is disposed between the first cylindrical portion 101 and the second cylindrical portion 102. One side of the fin 103 is connected to the first cylindrical portion 101, and the other side of the fin 103 is connected to the second cylindrical portion 102. The fin 103 extends along the axial direction of the profile 100 and is provided with a plurality of fins arranged at intervals along the circumference of the profile 100.

[0095] like Figures 1 to 6 As shown, an opening 10 is provided on the profile 100. An annular opening 10 can be provided on the second cylindrical portion 102 to expose the fins 103, thereby increasing the contact area between the profile 100 and the external air and achieving natural heat dissipation; or...

[0096] like Figures 7 to 11 As shown, an air inlet 11 and an air outlet 12 can be provided on the second cylindrical section 102, an annular circulation port 13 can be provided on the first cylindrical section 101, and a fan 14 can be provided on the inner circumference of the first cylindrical section 101. When the fan 14 operates, the airflow circulates inside and outside the profile 100 to achieve air cooling; or,

[0097] like Figures 12 to 15As shown, an inlet 15 and an outlet 16 can be provided on the second cylindrical section 102, and a pump 18 can be provided on the outside of the profile 100 to make the coolant circulate inside and outside the profile 100 to achieve liquid cooling heat dissipation.

[0098] In this embodiment, the interface is located at the ends of the first cylindrical portion 101 and the second cylindrical portion 102.

[0099] Specifically, the second interface is formed by the end of the second cylindrical portion 102 protruding outward relative to the fin plate 103, and the first interface is the end of the first cylindrical portion 101.

[0100] In this embodiment, at least part of the end of the second cylindrical portion 102 of the profile 100 protrudes outward relative to the end of the fin 103. The end of the front housing 31 or the rear housing 32 that mates with the profile 100 is provided with a second insertion portion 34 that is adapted to the inner diameter of the second cylindrical portion 102. The end of the second insertion portion 34 is provided with an extension wall 35 that extends radially toward the axis of the profile 100. When the second insertion portion 34 is inserted into the second cylindrical portion 102, the extension wall 35 abuts against the end of the fin 103 and / or the end of the first cylindrical portion 101. The extension wall 35 is provided with a first insertion portion 33 that extends into the first cylindrical portion 101 and is inserted into the end of the first cylindrical portion 101.

[0101] The first plug-in portion 33 and the first interface are sealed together, and the second plug-in portion 34 and the second interface are sealed together. Furthermore, at least part of the end of the fin plate 103 is spaced apart from the extension wall 35, thereby forming an annular channel 4 between the fin plate 103 and the extension wall 35 for airflow or liquid flow.

[0102] In this embodiment, a mounting plate 6 is provided inside the first cylindrical portion 101. The mounting plate 6 is arranged radially along the first cylindrical portion 101. The front housing 31 and the rear housing 32 are inserted into the front and rear ends of the radiator 1 and connected to the mounting plate 6 by screws. Preferably, a plurality of screws are arranged evenly along the circumference of the radiator 1. By setting the front housing 31 and the rear housing 32 to be inserted into the front and rear ends of the radiator 1 and connected to the mounting plate 6 inside the radiator 1 by a plurality of screws, the stability of the overall structure of the spotlight can be ensured. At the same time, the screws are hidden inside the spotlight, which can improve the aesthetics of the spotlight and also help improve the overall waterproof performance.

[0103] Specifically, the diameter of the mounting plate 6 is the same as the inner diameter of the first cylindrical part 101. A limiting part 104 protruding into the interior of the first cylindrical part 101 is provided on the inner wall of the first cylindrical part 101. The mounting plate 6 is installed inside the first cylindrical part 101 and abuts against the limiting part 104. It is connected to the front housing 31 and the rear housing 32 by screws.

[0104] In this embodiment, the extension walls 35 of the front housing 31 and the rear housing 32 are annular. The inner circumference of the extension wall 35 is provided with mounting holes. The mounting plate 6 is provided with screw holes that correspond to each screw. After the screw passes through the mounting holes on the inner circumference of the extension wall 35, it is tightened onto the mounting plate 6 to complete the assembly.

[0105] Preferably, in this embodiment, the extension walls 35 of the front housing 31 and the rear housing 32 are respectively provided with reinforcing ribs on the side away from the radiator 1. The reinforcing ribs extend radially along the extension walls 35 and are provided in a plurality of circumferentially spaced arrangement along the extension walls 35.

[0106] In this embodiment, the light energy module 2 of the light-collecting lamp is installed on the inner periphery of the heat sink 1, facing the front housing 31, and corresponding to the lens 9 at the front end of the front housing 31.

[0107] In some specific embodiments, the front housing 31 includes a front housing body and a lens 9 mounted on the front end of the front housing body, and the rear end of the front housing body is used to connect to the front end of the heat sink 1.

[0108] Preferably, a sealing structure is provided between the lens 9 and the front housing body.

[0109] Specifically, the light energy module 2 of the light-collecting lamp is mounted on the mounting plate 6 with screws on the side facing the front housing 31. The operator can replace the bulb of the light energy module 2.

[0110] The built-in power module 7 of the spotlight can be installed inside the rear housing 32 or outside the spotlight.

[0111] Specifically, the rear housing 32 is provided with a built-in power module that is electrically connected to the solar power module 2; and / or, the rear housing 32 is provided with a power supply module that is electrically connected to the solar power module 2 and / or the built-in power module, for connecting to an external power module outside the rear housing 32; and / or, the control module 8 is electrically connected to the solar power module 2 and to the built-in power module and / or the power supply module.

[0112] In some specific embodiments, a circuit board is provided inside the rear housing 32, the control module 8 is integrated on the circuit board, and the power supply module, the built-in power module 7, and the light energy module 2 are electrically connected to the circuit board.

[0113] In this embodiment, the circuit board is mounted on the rear inner wall of the rear housing 32, and the control module 8 includes an operation switch disposed on the rear wall of the rear housing 32, specifically a waterproof button.

[0114] The power module may consist only of a built-in power module disposed within the rear housing 32. When a built-in power module is disposed within the rear housing 32, the power supply module may be used to charge the built-in power module or to directly supply power to the spotlight.

[0115] When the spotlight is liquid-cooled, the built-in power module is electrically connected to the external pump 18 through the power supply module to supply power to the pump 18.

[0116] The power module may consist only of an external power module, which is a separately configured mobile power supply. This external power module can supply power to the collected solar energy via a power supply module. Alternatively, the external power module can also be used to power the pump 18 of the liquid-cooled radiator 1.

[0117] Of course, the spotlight can also be equipped with both a built-in power module and an external power module. In this case, the external power module serves as a backup power source for the spotlight. When long-term use is required, the spotlight can be powered by the external power module. When the spotlight's heat sink 1 is liquid-cooled, the external power module can also simultaneously power the pump 18.

[0118] Preferably, in this embodiment, the power supply module is connected to the external line using a magnetic power supply method.

[0119] The external wiring includes wiring for connecting to a power source, wiring for connecting to an external power module, and wiring for connecting to pump 18.

[0120] In some specific embodiments, a magnetic head is provided at the end of the circuit, and a magnetic groove adapted to the magnetic head is provided at the rear end of the rear housing 32. When the magnetic head is inserted into the magnetic groove, it is attracted to the rear housing 32 and powered by induction with the power supply module. This facilitates user connection of the circuit and further improves the waterproofness of the product.

[0121] In this embodiment, when a built-in power module is provided inside the rear housing 32, the axial length of the rear housing 32 is increased, thereby increasing the accommodating space of the rear housing 32.

[0122] If the rear housing 32 does not have a built-in power module, the axial dimension of the rear housing 32 can be appropriately shortened, making the spotlight more portable. The spotlight can be powered by an external power module during use.

[0123] In some specific embodiments, the rear housing 32 includes a rear housing body and a rear end cover, the rear end cover being disposed at the rear end of the rear housing body, and the front end of the rear housing body being used to connect to the rear end of the radiator 1.

[0124] Preferably, in this embodiment, a sealing structure is provided between the rear end cover and the rear shell body.

[0125] In this embodiment, by providing a sealing structure between the lens 9 and the front housing body, a sealing structure between the rear end cover and the rear housing body, a sealing structure between the front housing body and the heat sink 1, and a sealing structure between the rear housing body and the rear end of the heat sink 1, and by hiding the screw inside the light collector, the overall sealing performance of the product can be improved, achieving an immersion waterproof level.

[0126] Among them, the spotlight that uses air cooling heat dissipation can only achieve the spray waterproof level because the first cylindrical part 101 has a circulation port 13.

[0127] Preferably, in this embodiment, the profile 100 of the radiator 1 is an aluminum profile 100, and both the front shell 31 and the rear shell 32 are made of lightweight materials, resulting in a low overall density. Even if it falls into water, it can float on the surface and be easily found. This makes the product suitable for various usage scenarios.

[0128] Preferably, in this embodiment, the light-collecting lamp is also provided with a base, which is located at the bottom of the heat sink 1 to support the light-collecting lamp and ensure that the light-collecting lamp can be placed stably.

[0129] Preferably, in this embodiment, the base can also be configured as an adjustable angle structure, thereby enabling the tilt angle of the spotlight to be changed.

[0130] Preferably, in this embodiment, the light-collecting lamp is also provided with a handle, which is located on the top of the heat sink 1, so as to facilitate the user to move the light-collecting lamp.

[0131] Example 2

[0132] like Figures 1 to 15 As shown in the embodiment of the present invention, a heat sink 1 for a light-collecting lamp is introduced, including a profile 100. The profile 100 includes a first cylindrical portion 101 and a second cylindrical portion 102. The outer diameter of the first cylindrical portion 101 is smaller than the inner diameter of the second cylindrical portion 102. The second cylindrical portion 102 is sleeved on the outer periphery of the first cylindrical portion 101 and arranged around the first cylindrical portion 101. The outer wall of the first cylindrical portion 101 is spaced apart from the inner wall of the second cylindrical portion 102. A fin 103 is provided between the first cylindrical portion 101 and the second cylindrical portion 102. One side of the fin 103 is connected to the first cylindrical portion 101, and the other side of the fin 103 is connected to the second cylindrical portion 102. The fin 103 extends along the axial direction of the profile 100 and is provided with a plurality of fins arranged at intervals along the circumference of the profile 100.

[0133] In this embodiment, the first cylindrical portion 101 and the second cylindrical portion 102 can be coaxial or non-coaxial.

[0134] The width direction of the fin 103 can extend radially along the profile 100, or it can be set at an angle relative to the radial direction of the profile 100. When the width direction of the fin 103 is set at an angle to the radial direction of the profile 100, each fin 103 is inclined toward the same side of the radial direction of the profile 100.

[0135] The length direction of the fin 103 can be along the axial direction of the profile 100, or it can be set at an angle relative to the axial direction of the profile 100. When the length direction of the fin 103 is set at an angle to the axial direction of the profile 100, the included angle between each fin 103 and the axis of the profile 100 is the same.

[0136] That is, in this embodiment, the extension paths of each fin 103 on the first cylindrical portion 101 are parallel to each other on the side of the profile 100 that is close to the axis of the profile 100, and the extension paths of each fin 103 on the second cylindrical portion 102 are parallel to each other on the side of the profile 100 that is away from the axis of the profile 100. In other words, if the profile 100 is unfolded into a plane, each fin 103 is parallel to each other.

[0137] Preferably, in this embodiment, the plurality of fins 103 are evenly arranged along the circumference of the profile 100.

[0138] Preferably, in this embodiment, the first cylindrical portion 101 and the second cylindrical portion 102 are coaxial, the width direction of the fin 103 extends radially along the profile 100, and the length direction of the fin 103 extends axially along the profile 100, as an example for explanation.

[0139] like Figure 3 , 4 As shown, in this embodiment, the light-collecting lamp also includes a housing, which includes a front housing 31 and a rear housing 32, and the front housing 31 and the rear housing 32 are respectively connected to the front and rear ends of the profile 100.

[0140] In this embodiment, by providing openings 10 on the first cylindrical portion 101 and / or the second cylindrical portion 102, the cooling medium is allowed to circulate between the first cylindrical portion 101 and the second cylindrical portion 102 and / or inside the first cylindrical portion 101, thereby achieving heat dissipation.

[0141] In this embodiment, the cooling medium includes airflow and coolant.

[0142] Specifically, in this embodiment, the opening 10 is provided on the second cylindrical portion 102, and the cooling medium flows between the first cylindrical portion 101 and the second cylindrical portion 102 through the opening 10;

[0143] Alternatively, the opening 10 is provided on the first cylindrical portion 101 and the second cylindrical portion 102, and the cooling medium circulates between the first cylindrical portion 101 and the second cylindrical portion 102 and inside the first cylindrical portion 101 through the opening 10.

[0144] In this embodiment, the light energy module 2 is disposed inside the first cylindrical part 101.

[0145] When an opening 10 is provided on the first cylindrical section 101, if the cooling medium is airflow, it can flow directly inside the first cylindrical section 101; if the cooling medium is coolant, it needs to flow through a pipe inside the first cylindrical section 101.

[0146] like Figures 1 to 6 As shown, in some possible embodiments, the heat sink 1 is a natural heat sink. By cutting the profile 100, the contact area between the profile 100 and the outside air is increased, so that the airflow can flow naturally between the inside and outside of the profile 100 to ensure high heat dissipation efficiency.

[0147] In this embodiment, the axial length of the opening 10 is less than or equal to the axial length of the second cylindrical portion 102.

[0148] Specifically, in this embodiment, the opening 10 is provided on the second cylindrical portion 102 and extends circumferentially along the second cylindrical portion 102, thereby exposing the side of the fin 103 away from the axis of the profile 100. External air can contact the internal fin 103 and the first cylindrical portion 101 through the opening 10, thereby improving heat dissipation efficiency.

[0149] In this embodiment, the opening 10 can be located in the middle of the second cylindrical portion 102 or at the end of the second cylindrical portion 102. Alternatively, the second cylindrical portion 102 can be cut as a whole to form the opening 10, that is, the axial length of the opening 10 is equal to the axial length of the second cylindrical portion 102.

[0150] In this embodiment, the opening 10 can be a single opening disposed on the second cylindrical portion 102. The axial length of the opening 10 is less than or equal to the axial length of the second cylindrical portion 102. The opening 10 can also be provided in multiple forms arranged at intervals along the axial direction of the second cylindrical portion 102.

[0151] Specifically, when the opening 10 is located in the middle of the second cylindrical portion 102, the front housing 31 and rear housing 32 of the light-collecting lamp are connected to the ends of the first cylindrical portion 101 and / or the second cylindrical portion 102. When the opening 10 extends to the end of the second cylindrical portion 102, the front housing 31 and rear housing 32 of the light-collecting lamp are connected to the end of the first cylindrical portion 101.

[0152] Preferably, in this embodiment, when the diameter of the light-collecting lamp is large, in order to ensure the assembly effect with the front housing 31 and the rear housing 32, the opening 10 can be set in the middle of the second cylindrical part 102, and the front housing 31 and the rear housing 32 are respectively connected to the ends of the first cylindrical part 101 and the second cylindrical part 102.

[0153] Alternatively, the opening 10 may be provided on both the second cylindrical portion 102 and the first cylindrical portion 101.

[0154] Specifically, in this embodiment, at least one opening 10 is provided on the first cylindrical portion 101 and the second cylindrical portion 102 respectively, and the opening 10 extends circumferentially along the first cylindrical portion 101 or the second cylindrical portion 102.

[0155] The openings 10 on the first cylindrical portion 101 and the second cylindrical portion 102 are preferably provided in the middle of the first cylindrical portion 101 and the second cylindrical portion 102.

[0156] In this embodiment, when the spotlight has high requirements for waterproof performance, an opening 10 is provided only on the second cylindrical portion 102, and not on the first cylindrical portion 101. The front housing 31 and rear housing 32 of the spotlight are respectively sealed to the front and rear ends of the first cylindrical portion 101 of the profile 100, thereby preventing water from entering the spotlight. Specifically, the front housing 31 and rear housing 32 of the spotlight are respectively inserted into the front and rear ends of the first cylindrical portion 101, and a sealing ring 5 is provided at the overlap to ensure assembly and sealing effects.

[0157] like Figures 7 to 11 As shown, in some possible embodiments, the radiator 1 is air-cooled. The radiator 1 includes a fan 14, which forms an opening 10 on the second cylindrical portion 102 by cutting the profile 100, or forms an opening 10 on the first cylindrical portion 101 and the second cylindrical portion 102, so that the airflow circulates between the inside and outside of the profile 100 to improve the heat dissipation effect.

[0158] In this embodiment, the fan 14 can be installed inside the profile 100 or outside the profile 100.

[0159] Preferably, in this embodiment, the opening 10 includes an air inlet 11 and an air outlet 12 disposed on the second cylindrical portion 102, and a circulation port 13 disposed on the first cylindrical portion 101; the fan 14 is disposed on the inner periphery of the first cylindrical portion 101 and is used to drive the airflow to circulate between the first cylindrical portion 101 and the second cylindrical portion 102, and inside the first cylindrical portion 101.

[0160] Specifically, in this embodiment, the first cylindrical part 101 is provided with an installation plate 6 inside. The installation plate 6 divides the internal space of the first cylindrical part 101 into a first circulation chamber and a second circulation chamber. The circulation port 13 corresponds to the first circulation chamber, and the fan 14 is installed in the first circulation chamber.

[0161] In this embodiment, the circulation port 13 extends circumferentially along the first cylindrical section 101, the outlet end of the fan 14 is opposite to the circulation port 13, and the air outlet 12 on the first cylindrical section 101 corresponds to the outlet end of the fan 14. During the operation of the fan 14, external air is drawn into the space between the first cylindrical section 101 and the second cylindrical section 102 through the air inlet 11, circulates between the first cylindrical section 101 and the second cylindrical section 102, and then is discharged from the air outlet 12.

[0162] Preferably, in this embodiment, the air outlet 12 is configured as an arc extending circumferentially along the second cylindrical portion 102, and the two ends of the air outlet 12 extending circumferentially along the second cylindrical portion 102 correspond to the side of the fin 103 in the first range away from the axis of the profile 100. The two ends of the outlet end of the fan 14 extending circumferentially along the second cylindrical portion 102 correspond to the side of the fin 103 in the same range close to the axis of the profile 100. The air inlet 11 is disposed on the side of the air outlet 12 close to the second circulation chamber.

[0163] Preferably, in this embodiment, the air inlet 11 and the air outlet 12 are arranged side by side in the axial direction of the second cylindrical portion 102.

[0164] Thus, during the operation of the fan 14, after the airflow enters the space between the first cylindrical section 101 and the second cylindrical section 102 from the air inlet 11, it flows from the area covered by the air inlet 11 in the circumferential direction of the profile 100 between the fins 103 to the side away from the air outlet 12, and then flows into the first circulation chamber through the area not covered by the air inlet 11 in the circumferential direction of the profile 100 between the fins 103, and enters the first circulation chamber through the part of the circulation port 13 not covered by the outlet end of the fan 14.

[0165] After the airflow enters the first circulation chamber, it is discharged to the outside of the profile 100 through the fan 14 and the air outlet 12. As a result, the profile 100 as a whole has a high heat dissipation effect.

[0166] Preferably, in this embodiment, during the exhaust process, a portion of the airflow can flow through the air outlet 12 between the fins 103 in the area covered by the circumferential direction of the profile 100 to both sides of the air outlet 12.

[0167] Preferably, in this embodiment, the extension angle of the air inlet 11 in the circumferential direction of the second cylindrical portion 102 is less than or equal to 180°. More preferably, the extension angle of the air inlet 11 in the circumferential direction of the second cylindrical portion 102 is less than or equal to 90°.

[0168] Preferably, in this embodiment, the fan 14 is a volute fan 14, and the fan 14 is mounted on the mounting plate 6.

[0169] In this embodiment, annular channels 4 are formed between the two ends of the profile 100 and the front housing 31 and the rear housing 32, respectively. The annular channels 4 are correspondingly arranged with the space between the first cylindrical part 101 and the second cylindrical part 102. The annular channels 4 are used to communicate with the space between each of the two adjacent partitions.

[0170] The circulating airflow enters the annular channel 4 on one side of the second circulation chamber from the air inlet 11, enters the area between the fins 103 in the circumferential direction of the profile 100 that is not covered by the air inlet 11, and then enters the annular channel 4 on one side of the first circulation chamber, and enters the first circulation chamber through the annular channel 4 and the circulation port 13.

[0171] Preferably, in this embodiment, the air inlet 11 and the air outlet 12 are arranged side by side along the axial direction of the second cylindrical portion 102 at the bottom of the second cylindrical portion 102. Therefore, when the front housing 31 and the rear housing 32 are connected to the front and rear ends of the profile 100 of the radiator 1, the spotlight can achieve waterproof spraying.

[0172] In this embodiment, at least both ends of the first cylindrical portion 101 are inserted into the front housing 31 and the rear housing 32, and a sealing ring 5 is provided at the insertion position.

[0173] like Figures 12 to 14 As shown, in some possible embodiments, the radiator 1 is liquid-cooled. The radiator 1 includes a pump 18, which cuts the profile 100 to form an opening 10 on the second cylindrical portion 102, or forms an opening 10 on the first cylindrical portion 101 and the second cylindrical portion 102, so that the coolant circulates between the inside and outside of the profile 100 to improve the heat dissipation effect.

[0174] In this embodiment, if coolant is to circulate inside the first cylindrical section 101, then a pipe for supplying coolant circulation needs to be provided inside the profile 100.

[0175] Preferably, in this embodiment, the coolant does not enter the interior of the first cylindrical section 101.

[0176] Specifically, the opening 10 includes an inlet 15 and an outlet 16 disposed on the second cylindrical part 102. A liquid storage structure and a pump 18 are disposed on the outside of the profile 100. The liquid storage structure and the pump 18 are connected in series between the inlet 15 and the outlet 16 through pipelines.

[0177] Preferably, the inlet 15 and outlet 16 correspond to the spaces between different adjacent fins 103, and / or the inlet 15 and outlet 16 are located near the top of the profile 100 to ensure that the coolant fills the space between the first cylindrical section 101 and the second cylindrical section 102 before circulating to the outside of the profile 100.

[0178] Specifically, annular channels 4 are provided between the two ends of the profile 100 and the front housing 31 and the rear housing 32, respectively. The annular channels 4 are correspondingly provided with the space between the first cylindrical part 101 and the second cylindrical part 102. The annular channels 4 are used to communicate with the space between each of the two adjacent partitions.

[0179] The pump 18 is located between the inlet 15 and the storage structure. The pump 18 draws coolant from the storage structure and fills the profile 100 with coolant. After the coolant fills the space between the first cylindrical part 101 and the second cylindrical part 102 of the profile 100 through the annular channel 4, it is discharged from the outlet 16 and discharged into the storage structure.

[0180] Specifically, after the coolant fills the space between the first cylindrical section 101 and the second cylindrical section 102 of the profile 100, the circulation method is as follows: it is filled into the annular channel 4 on the side near the inlet 15 through the inlet 15, and then flows into the annular channel 4 on the side near the outlet 16 through the space between two adjacent fins 103 that do not correspond to the inlet 15. Then, it flows into the space between two adjacent fins 103 that correspond to the outlet 16 through the annular channel 4, and flows out of the profile 100 from the outlet 16.

[0181] In this embodiment, the liquid storage structure can be provided separately by the manufacturer, such as by designing a water tank accessory compatible with the spotlight for user convenience. Alternatively, the user can prepare the liquid storage structure themselves; for example, the storage structure can be a bucket, kettle, or similar container.

[0182] Preferably, in this embodiment, the pump is installed outside the second cylindrical section.

[0183] Preferably, in this embodiment, the liquid inlet 15 and the liquid outlet 16 are arranged side by side along the axial direction of the profile 100 and are connected to the space between two adjacent fins 103.

[0184] The inlet 15 and outlet 16 are respectively equipped with connectors 17 for connecting pipelines. The connector 17 includes a first part 171 connected to the profile 100 and a second part 172 connected to the first part 171. The end of the second part 172 away from the first part 171 is used to connect to an external pipeline.

[0185] Specifically, the first part 171 is tubular, with one end threadedly connected to the inlet 15 or outlet 16, and the other end protruding from the outer surface of the profile 100. The second part 172 is fitted onto the other end of the first part 171 at one end, and the other end of the second part 172 is inserted into an external pipeline.

[0186] Preferably, in this embodiment, the second part 172 of the connector 17 on the inlet 15 and outlet 16 is connected as one unit and installed on the second cylindrical part 102 of the profile 100 by screws, thereby ensuring the installation stability of the connector 17.

[0187] In this embodiment, a radial protrusion is provided in the middle of the first part 171, and the operator can tighten the first part 171 of the connector 17 onto the profile 100 through the radial protrusion.

[0188] Preferably, in this embodiment, a sealing ring 5 is provided at the connection between the radial protrusion and the first part 171. The radial protrusion presses the sealing ring 5 onto the profile 100 to ensure the sealing effect at the liquid inlet 15 and the liquid outlet 16.

[0189] Preferably, in this embodiment, the end of the second portion 172 away from the first portion 171 extends along the axial direction of the profile 100, and the ends of the second portion 172 of the connector 17 at the inlet 15 and outlet 16 extend in a direction away from each other. A protective cover is also provided on the outside of the radiator 1 to partially conceal the connector 17 within the cover. External pipes are connected to the connector 17 at the inlet 15 and outlet 16 through through holes at both ends of the protective cover.

[0190] In this embodiment, the annular channel 4 in the spotlight of the air-cooled radiator 1 and the liquid-cooled radiator 1 is formed by splicing and combining the front shell 31, the rear shell 32 and the profile 100.

[0191] Specifically, the front housing 31 and the rear housing 32 are respectively inserted into the front and rear ends of the profile 100. The front housing 31 and the rear housing 32 are each provided with a first insertion part 33 and a second insertion part 34 that are respectively inserted into the ends of the first cylindrical part 101 and the second cylindrical part 102 of the profile 100. The first insertion part 33 and the second insertion part 34 are respectively inserted into the first cylindrical part 101 and the second cylindrical part 102, and a sealing ring 5 is provided between the first insertion part 33 and the first cylindrical part 101, and between the second insertion part 34 and the second cylindrical part 102.

[0192] like Figure 15 As shown, the outer diameter of the first plug portion 33 is smaller than the outer diameter of the second plug portion 34. The first plug portion 33 is at least partially protruding from the end face of the second plug portion 34 in the axial direction. The end of the second plug portion 34 is connected to the root of the first plug portion 33 by an extension wall 35 extending radially. Specifically, at least part of the end of the second cylindrical portion 102 of the profile 100 protrudes outward relative to the end of the fin 103. The end of the front housing 31 or the rear housing 32 that mates with the profile 100 is provided with a second insertion portion 34 that is adapted to the inner diameter of the second cylindrical portion 102. The end of the second insertion portion 34 is provided with an extension wall 35 that extends radially toward the axis of the profile 100. When the second insertion portion 34 is inserted into the second cylindrical portion 102, the extension wall 35 abuts against the end of the fin 103 and / or the end of the first cylindrical portion 101. The extension wall 35 is provided with a first insertion portion 33 that extends into the first cylindrical portion 101 and is inserted into the end of the first cylindrical portion 101.

[0193] Preferably, in this embodiment, the overlapping portions of the first insertion portion 33 and the first cylindrical portion 101, and the overlapping portions of the second insertion portion 34 and the second cylindrical portion 102 are respectively provided with mounting grooves 36 extending circumferentially along the profile 100. The sealing ring 5 is sleeved on the first insertion portion 33 and the second insertion portion 34 and is limited and installed in the mounting grooves 36 on the first insertion portion 33 and the second insertion portion 34. When the first insertion portion 33 and the second insertion portion 34 are inserted with the first cylindrical portion 101 and the second cylindrical portion 102, the sealing ring 5 elastically abuts against the bottom of the mounting groove 36 and the inner wall of the first cylindrical portion 101 and the inner wall of the second cylindrical portion 102, thereby sealing the space between the first insertion portion 33 and the first cylindrical portion 101, and between the second insertion portion 34 and the second cylindrical portion 102.

[0194] Preferred, such as Figure 7 , Figure 8 and Figure 13 As shown, in this embodiment, at least a portion of the end of the fin plate 103 is spaced apart from the extension wall 35, thereby forming an annular channel 4 between the fin plate 103 and the extension wall 35.

[0195] In some specific embodiments, the end of the first cylindrical portion 101 abuts against the extension wall 35, and the end of the fin 103 extends at least partially at an angle toward the center of the profile 100.

[0196] Preferably, in this embodiment, at least part of the two ends of the fin plate 103 extending along the axial direction of the profile 100 extend obliquely toward the middle of the profile 100 in a direction close to or away from the axis of the profile 100.

[0197] Preferably, in this embodiment, the end of the fin 103 of the profile 100 on the side away from the axis of the profile 100 is flush with the end of the first cylindrical portion 101. When the front housing 31 or the rear housing 32 is inserted into the end of the profile 100, the end of the first cylindrical portion 101 abuts against the extension wall 35, and the end of the fin 103 on the side away from the first cylindrical portion 101 at least partially abuts against the extension wall 35. Furthermore, at least both ends of the fin 103 extend obliquely towards the center of the profile 100 in a direction close to the axis of the profile 100, forming a gap with the extension wall 35. Thus, the annular channel 4 can be formed, and the installation stability between the front housing 31 or the rear housing 32 and the profile 100 can be improved.

[0198] In some specific embodiments, a smaller heat sink 1 using natural heat dissipation is suitable for cooling a spotlight with a power of 5W to 10W; a larger heat sink 1 using natural heat dissipation is suitable for cooling a spotlight with a power of 10W to 15W; a heat sink 1 using air cooling is suitable for cooling a spotlight with a power of 15W to 25W; and a heat sink 1 using liquid cooling is suitable for cooling a spotlight with a power of 25W to 40W.

[0199] In this embodiment, the heat sink 1 is made of a profile 100, which includes a first cylindrical part 101, a second cylindrical part 102, and a fin 103 connected between the two. This allows production personnel to make the profile 100 suitable for different heat dissipation methods by setting openings 10 at different positions on the profile 100. That is, after the profile 100 is made by a single mold, different forms of heat sink 1 can be produced by subsequent cutting and processing of the profile 100. This reduces the production cost of the heat sink 1 and improves the production efficiency of the heat sink 1. In addition, since the heat sink 1 is made of a single profile 100, it can be used to replace different spotlights in the later stages of use. Users can purchase heat sink 1 separately to combine spotlights of different wattages, which helps to save on usage costs for users.

[0200] In this embodiment, when the front housing 31 and rear housing 32 of the light-collecting lamp are installed with the profile 100, the front housing 31 and rear housing 32 are respectively connected to the mounting plate 6 in the middle of the profile 100 by screws.

[0201] In some specific embodiments, the diameter of the mounting plate 6 is the same as the inner diameter of the first cylindrical portion 101 of the profile 100. A limiting portion 104 protruding into the interior of the first cylindrical portion 101 is provided on the inner wall of the first cylindrical portion 101. The mounting plate 6 is installed inside the first cylindrical portion 101 and abuts against the limiting portion 104. It is connected to the front housing 31 and the rear housing 32 by screws.

[0202] Specifically, in this embodiment, the mounting plate 6 is installed inside the first cylindrical portion 101 from the end where the profile 100 connects to the rear housing 32. First, the front housing 31 is connected to the mounting plate 6 with screws, so that the radiator 1, the mounting plate 6, and the front housing 31 are integrated as one unit. Then, the rear housing 32 is connected to the mounting plate 6. Alternatively, the mounting plate 6 can be installed on the rear housing 32 first, then the radiator 1 can be fitted onto the rear housing 32, and finally the front housing 31 can be installed.

[0203] The installation steps and methods can be adjusted according to the specific internal structure of the front housing 31 and the rear housing 32. Specifically, the part with a complex internal structure can be connected to the mounting plate 6 first, and then the screws can be installed from the inside of the other part.

[0204] In this embodiment, the solar energy module 2 is installed on the side of the mounting plate 6 facing the front housing 31.

[0205] In this embodiment, a lens 9 is provided on the front housing 31.

[0206] The rear housing 32 is provided with a built-in power module 7; or, the rear housing 32 is not provided with a built-in power module 7, and an external power module is provided outside the light-collecting lamp to power the light module 2.

[0207] Alternatively, a built-in power module can be installed inside the rear housing 32, and an external power module can be installed outside the spotlight.

[0208] In this embodiment, since the wires, control module 8, and built-in power module 7 are mainly concentrated on the rear housing 32, the light energy module 2 can be first installed on the mounting plate 6 and connected to the control module 8 and built-in power module 7 on the rear housing 32 via wiring. Then, the mounting plate 6 is installed on the rear housing 32 and fixed with screws, adjusting the distance between the rear housing 32 and the mounting plate 6. When installing the heat sink 1, the heat sink 1 is sleeved on the outer periphery of the mounting plate 6 and fixed to the end of the rear housing 32. At this time, the mounting plate 6 abuts against the limiting part 104 on the inner periphery of the heat sink 1. Then, the front housing 31 is inserted into the end of the heat sink 1 away from the rear housing 32 and fixed to the mounting plate 6 with screws. At this time, the front housing 31, the heat sink 1, and the rear housing 32 are connected as one unit. Finally, the lens 9 is installed on the front housing 31.

[0209] Example 3

[0210] like Figures 16 to 20 As shown in this embodiment of the invention, a light-collecting lamp is introduced. The light-collecting lamp can be used in rainy conditions or in conditions requiring immersion in water, and it ensures that the light-collecting lamp will not be damaged if it accidentally falls into water.

[0211] In this embodiment, the light-collecting lamp includes a front housing 31, a rear housing 32, and a heat sink 1 connected between the front housing 31 and the rear housing 32, wherein the front housing 31, the rear housing 32 and the heat sink 1 are sealed together.

[0212] like Figure 17 As shown, in this embodiment, a lens 9 is provided at the front end of the front housing 31. The lens 9 is arranged opposite to the light energy module 2 inside the heat sink 1. Different lenses 9 can be switched for different usage scenarios, and / or the lens 9 can be focused.

[0213] In this embodiment, the front housing 31 is cylindrical, and the lens 9 extends at least partially from the front end of the front housing 31 into the front housing 31. A first sealing structure 93 is provided at the overlap between the lens 9 and the front housing 31.

[0214] Specifically, the first sealing structure 93 includes a first sealing ring disposed between the lens 9 and the front housing 31. The inner circumference of the first sealing ring elastically abuts against the lens 9, and the outer circumference elastically abuts against the front housing 31. By setting the lens 9 and the front housing 31 to at least partially overlap, and disposing of the first sealing ring at the overlap, a seal can be achieved between the lens 9 and the housing in the radial direction of the light collector, preventing external water or moisture from entering the light collector through the gap between the lens 9 and the housing, thereby improving the waterproof performance of the light collector.

[0215] Preferably, in this embodiment, the lens 9 can move axially relative to the front housing 31, thereby adjusting the distance between the lens 9 and the light energy module 2 to achieve focusing.

[0216] In some specific embodiments, the lens 9 is threadedly engaged with the front housing 31 to adjust the distance between the lens 9 and the light energy module 2 inside the heat sink 1. The user can also adjust the focus by twisting the lens 9.

[0217] In this embodiment, an annular groove 91 is provided on the outer peripheral wall of the lens 9, and a first sealing ring is embedded in the annular groove 91. The inner diameter of the first sealing ring is smaller than the outer diameter at the bottom of the annular groove 91, and the outer diameter of the first sealing ring is larger than the outer diameter of the lens 9. The annular groove 91 can limit the position of the first sealing ring, allowing it to move with the lens 9. This ensures the sealing effect of the first sealing ring on the gap between the lens 9 and the front housing 31. In addition, the first sealing ring can be maintained or replaced when the lens 9 is removed, facilitating the disassembly and assembly of the first sealing ring.

[0218] Preferably, in this embodiment, the first sealing ring is provided with at least two rings arranged at intervals along the axial direction of the lens 9, and the outer peripheral wall of the lens 9 is provided with annular grooves 91 corresponding to each of the first sealing rings.

[0219] In some specific embodiments, a threaded groove 92 is provided on the outer peripheral wall of the lens 9. The threaded groove 92 extends circumferentially along the outer peripheral wall of the lens 9, and the angle between the extension direction of the threaded groove 92 and the axis of the lens 9 is less than 90°, that is, the extension direction of the threaded groove 92 is a thread shape. A limiting protrusion 311 corresponding to the threaded groove 92 is provided on the inner peripheral wall of the front housing 31. The limiting protrusion 311 extends into the threaded groove 92 and cooperates with the threaded groove 92 to limit the movement of the lens 9.

[0220] Specifically, the threaded groove 92 extends to the rear end of the lens 9. When the lens 9 is rotated, the limiting protrusion 311 can enter the threaded groove 92 from the rear end of the lens 9. The shape of the limiting protrusion 311 is the same as the internal shape of the threaded groove 92. The limiting protrusion 311 abuts against the groove wall of the threaded groove 92 to achieve axial limiting of the lens 9.

[0221] Preferably, in some possible embodiments, the limiting protrusions 311 can be arranged in multiple circumferentially spaced along the front housing 31, and the multiple limiting protrusions 311 correspond to the threaded groove 92 in spatial position, that is, the arrangement path of the multiple limiting protrusions 311 is the same as the extension path of the threaded groove 92.

[0222] Preferably, in this embodiment, the annular groove 91 is disposed on the front side of the threaded groove 92. This avoids interference between the first sealing structure and the limiting protrusion 311, ensuring that the lens 9 can be smoothly assembled and disassembled.

[0223] Preferably, in some possible embodiments, the front housing 31 is provided with a first limiting cover 94 for limiting the movement of the lens 9 at its front end.

[0224] Specifically, such as Figures 17 to 19 As shown, the lens 9 includes a first segment with an outer diameter that is the same as the inner diameter of the front housing 31, and a second segment disposed at the front end of the first segment with an outer diameter smaller than the outer diameter of the first segment. The second segment extends at least partially from the front end of the front housing 31 to the outside of the front housing 31. The first limiting cover 94 is disposed at least partially opposite to the front end of the first segment.

[0225] In this embodiment, the first and second segments of the lens 9 are coaxially arranged, and the first sealing structure 93 is disposed between the first segment and the front housing 31. That is, the threaded groove 92 and the annular groove 91 are both disposed on the first segment of the lens 9. Thus, during the focusing process of the light-collecting lamp, when the lens 9 moves to a certain position outside the front housing 31, the front end of the first segment of the lens 9 abuts against the first limiting cover 94 to limit the lens 9. This can prevent the annular groove 91 used to accommodate the first sealing ring from moving outside the front housing 31, thus ensuring the working stability of the product.

[0226] In some specific embodiments, the first limiting cover 94 includes a first axial extension 941 sleeved on the front end of the front housing 31, and a first radial extension 942 extending from the front end of the first axial extension 941 toward the axis of the front housing 31. The inner diameter of the first radial extension 942 is smaller than the inner diameter of the front housing 31, thereby enabling the lens 9 to be stopped.

[0227] Preferably, in this embodiment, the inner diameter of the first radial extension 942 is the same as the outer diameter of the first segment of the lens 9.

[0228] In some preferred embodiments, the first radial extension 942 is spaced apart from the front end of the front housing 31, and the distance between them is less than the distance between the annular groove 91 on the side away from the threaded groove 92 and the front end of the first segment of the lens 9. This allows for an increase in the movable range of the lens 9 while maintaining the sealing effect of the first sealing structure 93, further enhancing the user experience.

[0229] Preferably, the distance between the first radial extension 942 and the front end of the front housing 31 is slightly smaller than the distance between the annular groove 91 on the side away from the threaded groove 92 and the front end of the first segment of the lens 9. It is only necessary to ensure that the first sealing ring in the annular groove 91 does not move outside the front housing 31.

[0230] In some specific embodiments, the first limiting cover 94 is engaged with the front housing 31.

[0231] Specifically, a claw 943 is provided at the rear end of the first axial extension 941. The claw 943 extends from the rear end of the first axial extension 941 around the front housing 31, with the claw portion of the claw 943 facing the inner circumference of the first limiting cover 94. A groove 312 corresponding to the claw portion of the claw 943 is provided on the outer peripheral wall of the front housing 31. The first axial extension 941 is sleeved on the front end of the front housing 31, and the claw 943 of the first axial extension 941 engages in the groove 312 of the front housing 31, locking the relative position between the first limiting cover 94 and the front housing 31.

[0232] The front end of the front housing 31 is provided with a stepped section whose outer diameter increases from front to rear. The stepped section is inserted into the first axial extension 941, and the internal shape of the first axial extension 941 is the same as the external shape of the front end of the front housing 31. This facilitates the installation of the first limiting cover 94 and ensures the installation stability of the first limiting cover 94 after installation.

[0233] Specifically, in this embodiment, the claw 943 includes a neck extending rearward from the rear end of the first axial extension 941, and a claw portion protruding and extending from the rear end of the neck in a direction close to the axis of the front housing 31. When the first limiting cover 94 is installed, the claw portion abuts against the front housing 31 on the front side of the slot 312, causing the claw 943 to undergo elastic deformation. When the claw portion moves to correspond with the slot 312, the claw 943 rebounds and the claw portion is embedded in the slot 312.

[0234] Preferably, in this embodiment, the claws 943 are arranged in a plurality of circumferentially, and a gap is provided between adjacent claws 943, thereby improving the installation stability between the first limiting cover 94 and the front housing 31, and at the same time improving the aesthetics of the light-collecting lamp.

[0235] The inner periphery of the rear end of the claw 943 is configured as an inclined surface extending in a direction away from the axis of the first limiting cover 94 along the installation direction of the first limiting cover 94, that is, an inclined surface extending in a direction away from the axis of the first limiting cover 94 from front to back.

[0236] In this embodiment, the rear housing 32 is also cylindrical. The front end of the rear housing 32 is sealed to the radiator 1. The rear end of the rear housing 32 is provided with a rear end cover 321, which can close the rear end of the rear housing 32.

[0237] Specifically, in this embodiment, the rear end cover 321 extends at least partially from the rear end of the rear housing 32 into the rear housing 32, and a second sealing structure 323 is provided at the overlap between the rear end cover 321 and the rear housing 32.

[0238] Preferably, the outer diameter of the front end of the rear end cover 321 is larger than the inner diameter of the rear housing 32. The front end of the rear end cover 321 is provided with a plug-in section. The outer diameter of the plug-in section is the same as the inner diameter of the rear housing 32. The rear housing 32 is plugged into the rear end of the rear housing 32 through the plug-in section. The second sealing structure 323 is disposed between the plug-in section and the rear housing 32.

[0239] Preferably, the second sealing structure 323 includes a second sealing ring disposed on the insertion section. Specifically, the insertion section is provided with an annular groove 91, and the second sealing ring is disposed within the annular groove 91.

[0240] like Figure 20 As shown, in this embodiment, the rear end of the rear housing 32 is provided with a second limiting cover 322. The second limiting cover 322 is sleeved on the rear end of the rear housing 32 and snapped into the rear housing 32. The second limiting cover 322 at least partially abuts against the rear side of the rear end cover 321 to axially limit the rear end cover 321.

[0241] In this embodiment, the structure of the second limiting cover 322 is the same as that of the first limiting cover 94. Specifically, the second limiting cover 322 includes a second axial extension portion extending along the axial direction of the rear housing 32, and a second radial extension portion extending from the rear end of the second axial extension portion toward the axis of the rear housing 32.

[0242] The second axial extension is sleeved on the rear end of the rear housing 32. The front end of the second axial extension is provided with a claw 943. The outer peripheral wall of the rear housing 32 is provided with a groove 312 corresponding to the claw of the claw 943. The claw of the claw 943 is engaged in the groove 312, clamping the edge of the rear end cover 321 between the second radial extension and the rear end of the rear housing 32.

[0243] In this embodiment, the rear end cover 321 is groove-shaped, and the groove of the rear end cover 321 is provided with a radially outward protruding edge. The second limiting cover 322 is sleeved on the rear end of the rear end cover 321 and the rear housing 32. The claw 943 on the second limiting cover 322 engages with the slot 312 on the rear housing 32 to realize the installation of the rear end cover 321.

[0244] In this embodiment, a circuit board is provided inside the groove bottom of the rear end cover 321, and the circuit board is electrically connected to the power module of the spotlight. A power supply module is also installed on the groove bottom of the rear end cover 321, and the power supply module is electrically connected to the circuit board. The power supply module is connected to the external line using a magnetic power supply method.

[0245] The inner side of the groove bottom of the rear cover 321 is also provided with a display screen, which can be a liquid crystal screen.

The light-transmitting area can be a glass plate embedded in the rear cover 321, and sealant can be filled between the two to ensure a seal with the rear cover 321.

[0246] A waterproof button is also provided on the bottom of the groove of the rear cover 321. The waterproof button is electrically connected to the circuit board, and the user can control the spotlight through the waterproof button.

[0247] In this embodiment, the rear end of the rear housing 32 is provided with a stepped section whose outer diameter increases from rear to front. The stepped section is inserted into the second axial extension, and the internal shape of the second axial extension is the same as the external shape of the rear end of the rear housing 32. This facilitates the installation of the second limiting cover 322.

[0248] Preferably, in this embodiment, the second axial extension portion has a plurality of claws 943 arranged circumferentially, and a gap is provided between adjacent claws 943, thereby improving the installation stability between the second limiting cover 322 and the front housing 31, and at the same time improving the aesthetics of the spotlight.
