[0065] Embodiment 1

[0066] As Figures 16 to 20 shown, in the embodiment of the present utility model, a spotlight is introduced. The spotlight can be used in rainy conditions or in conditions where the spotlight needs to be immersed in water. At the same time, when the spotlight accidentally falls into the water, it can ensure that the spotlight is not damaged.

[0067] In this embodiment, the spotlight includes a front housing 31, a rear housing 32, and a radiator 1 connected between the front housing 31 and the rear housing 32. The front housing 31, the rear housing 32, and the radiator 1 are hermetically connected.

[0068] As Figure 17 shown, in this embodiment, a lens 9 is provided at the front end of the front housing 31. The lens 9 is disposed opposite to the light energy module 2 inside the radiator 1. Facing different usage scenarios, different lenses 9 can be switched and / or the lens 9 can be focused.

[0069] In this embodiment, the front housing 31 is provided in a cylindrical shape. At least a part of the lens 9 extends from the front end of the front housing 31 into the front housing 31. A first sealing structure 93 is provided at the overlapping portion of the lens 9 and the front housing 31.

[0070] Specifically, the first sealing structure 93 includes a first sealing ring provided between the lens 9 and the front housing 31. The inner circumference of the first sealing ring is elastically abutted against the lens 9, and the outer circumference is elastically abutted against the front housing 31. By providing at least partial overlap between the lens 9 and the front housing 31 and providing a first sealing ring at the overlapping portion of the lens 9 and the front housing 31, it is possible to achieve sealing between the lens 9 and the housing in the radial direction of the spotlight, preventing external water or water vapor from entering the interior of the spotlight through the gap between the lens 9 and the housing, and improving the waterproof performance of the spotlight.

[0071] Preferably, in this embodiment, the lens 9 can be axially moved relative to the front housing 31, thereby adjusting the distance between the lens 9 and the light energy module 2 to achieve focusing.

[0072] In some specific embodiments, the lens 9 is in threaded engagement with the front housing 31 for adjusting the distance between the lens 9 and the light energy module 2 inside the radiator 1. The user can also focus by turning the lens 9.

[0073] In this embodiment, an annular groove 91 is provided on the outer peripheral wall of the lens 9, and the 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 first sealing ring, enabling the first sealing ring to move with the lens 9, ensuring the sealing effect of the gap between the lens 9 and the front housing 31. Additionally, when the lens 9 is removed, the first sealing ring can be maintained or replaced, facilitating the disassembly and assembly of the first sealing ring.

[0074] Preferably, in this embodiment, at least two circles of the first sealing rings are arranged at intervals along the axial direction of the lens 9, and annular grooves 91 corresponding to each first sealing ring are provided on the outer peripheral wall of the lens 9.

[0075] In some specific embodiments, a threaded groove 92 is provided on the outer peripheral wall of the lens 9. The threaded groove 92 extends along the circumferential direction of the lens 9 on the outer peripheral wall of the lens 9, and the included angle between the extending direction of the threaded groove 92 and the axis of the lens 9 is less than 90°, that is, the extending direction of the threaded groove 92 is in a thread shape. A limiting projection 311 corresponding to the threaded groove 92 is provided on the inner peripheral wall of the front housing 31, and the limiting projection 311 extends into the threaded groove 92 to cooperate with the threaded groove 92 to limit the lens 9.

[0076] Specifically, the threaded groove 92 extends to the rear end of the lens 9. By rotating the lens 9, the limiting projection 311 can enter the threaded groove 92 from the rear end of the lens 9. The shape of the limiting projection 311 is the same as the inner shape of the threaded groove 92, and the limiting projection 311 abuts against the groove wall of the threaded groove 92 to achieve axial limitation of the lens 9.

[0077] Preferably, in some possible embodiments, a plurality of the limiting projections 311 can be arranged at intervals along the circumferential direction of the front housing 31, and the plurality of limiting projections 311 all correspond to the threaded groove 92 in terms of spatial position, that is, the arrangement path of the plurality of limiting projections 311 is the same as the extending path of the threaded groove 92.

[0078] Preferably, in this embodiment, the annular groove 91 is provided on the front side of the threaded groove 92. Thus, it is possible to avoid interference between the first sealing structure and the limiting projection 311, ensuring the smooth disassembly and assembly of the lens 9.

[0079] Preferably, in some possible embodiments, a first limiting cover 94 for limiting the movement of the lens 9 is provided at the front end of the front housing 31.

[0080] Specifically, as Figures 17 to 19 shown, the lens 9 includes a first section having the same outer diameter as the inner diameter of the front housing 31, and a second section provided at the front end of the first section and having an outer diameter smaller than that of the first section. At least a part of the second section extends from the front end of the front housing 31 to the outside of the front housing 31, and at least a part of the first limiting cover 94 is disposed opposite to the front end of the first section.

[0081] In this embodiment, the first section and the second section of the lens 9 are coaxially arranged, and the first sealing structure 93 is provided between the first section and the front housing 31. That is, the threaded groove 92 and the annular groove 91 are both provided on the first section of the lens 9. Thus, during the focusing process of the spotlight, when the lens 9 moves out of the front housing 31 to a certain position, the front end of the first section of the lens 9 abuts against the first limiting cover 94, realizing the limitation of the lens 9, which can prevent the annular groove 91 for accommodating the first sealing ring from moving to the outside of the front housing 31 and ensure the working stability of the product.

[0082] In some specific embodiments, the first limiting cover 94 includes a first axially extending portion 941 sleeved on the front end of the front housing 31, and a first radially extending portion 942 extending from the front end of the first axially extending portion 941 towards the axis of the front housing 31. The inner diameter of the first radially extending portion 942 is smaller than the inner diameter of the front housing 31, so as to be able to abut against the lens 9.

[0083] Preferably, in this embodiment, the inner diameter of the first radially extending portion 942 is the same as the outer diameter of the first section of the lens 9.

[0084] In some preferred embodiments, the first radially extending portion 942 and the front end of the front housing 31 are spaced apart, and the distance between them is 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 section of the lens 9. Thus, on the premise of ensuring the sealing effect of the first sealing structure 93, the movable range of the lens 9 can be increased, and the user experience can be further improved.

[0085] Preferably, the distance between the first radially extending portion 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 section of the lens 9, and it only needs to ensure that the first sealing ring in the annular groove 91 does not move to the outside of the front housing 31.

[0086] In some specific embodiments, the first limiting cover 94 and the front housing 31 are in snap-fit connection.

[0087] Specifically, a claw 943 is provided at the rear end of the first axially extending portion 941. The claw 943 extends around the front housing 31 from the rear end of the first axially extending portion 941, and the claw portion of the claw 943 faces the inner circumference of the first limiting cover 94. A clamping 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 axially extending portion 941 is sleeved on the front end of the front housing 31, and the claw 943 of the first axially extending portion 941 is clamped in the clamping groove 312 of the front housing 31 to lock the relative position between the first limiting cover 94 and the front housing 31.

[0088] A stepped section with an increasing outer diameter from front to back is provided at the front end of the front housing 31. The stepped section is inserted into the first axially extending portion 941, and the inner shape of the first axially extending portion 941 is the same as the outer shape of the front end of the front housing 31. Thus, it is convenient to install the first limiting cover 94, and after the first limiting cover 94 is installed, the installation stability of the first limiting cover 94 can be ensured.

[0089] Specifically, in this embodiment, the claw 943 includes a neck extending backward from the rear end of the first axially extending portion 941, and a claw portion protruding and extending from the rear end of the neck toward the axis of the front housing 31. When the first limiting cover 94 is installed, the claw portion abuts against the front housing 31 in front of the clamping groove 312, causing elastic deformation of the claw 943. When the claw portion moves to correspond to the clamping groove 312, the claw 943 rebounds and the claw portion is embedded in the clamping groove 312.

[0090] Preferably, in this embodiment, a plurality of claws 943 arranged circumferentially are provided, and a gap is provided between adjacent two claws 943. Thus, the installation stability between the first limiting cover 94 and the front housing 31 can be improved, and at the same time, the aesthetic property of the spotlight can be improved.

[0091] The inner circumference at the rear end of the claw 943 is provided with an inclined surface extending obliquely 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 obliquely in a direction away from the axis of the first limiting cover 94 from front to back.

[0092] In this embodiment, the rear housing 32 is also provided in a cylindrical shape. The front end of the rear housing 32 is hermetically connected to the radiator 1, and a rear end cover 321 is provided at the rear end of the rear housing 32. The rear end cover 321 can close the rear end of the rear housing 32.

[0093] Specifically, in this embodiment, at least part of the rear end cover 321 extends from the rear end of the rear housing 32 into the rear housing 32, and a second sealing structure 323 is provided at the overlapping portion of the rear end cover 321 and the rear housing 32.

[0094] 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. A plug-in section is provided at the front end of the rear end cover 321. 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 in plug-in fit with the rear end of the rear housing 32 through the plug-in section. The second sealing structure 323 is arranged between the plug-in section and the rear housing 32.

[0095] Preferably, the second sealing structure 323 includes a second sealing ring arranged on the plug-in section. Specifically, an annular groove 91 is provided on the plug-in section, and the second sealing ring is arranged in the annular groove 91.

[0096] As Figure 20 shown, in this embodiment, a second limit cover 322 is provided at the rear end of the rear housing 32. The second limit cover 322 is sleeved on the rear end of the rear housing 32 and is snap-connected to the rear housing 32. At least part of the second limit cover 322 abuts against the rear side of the rear end cover 321 to axially limit the rear end cover 321.

[0097] In this embodiment, the structure of the second limit cover 322 is the same as that of the first limit cover 94. Specifically, the second limit cover 322 includes a second axially extending portion extending along the axial direction of the rear housing 32, and a second radially extending portion extending from the rear end of the second axially extending portion towards the axis of the rear housing 32.

[0098] The second axially extending portion is sleeved on the rear end of the rear housing 32. A claw 943 is provided at the front end of the second axially extending portion. A slot 312 corresponding to the claw portion of the claw 943 is provided on the outer peripheral wall of the rear housing 32. The claw portion of the claw 943 is snap-connected in the slot 312 to clamp the edge of the rear end cover 321 between the second radially extending portion and the rear end of the rear housing 32.

[0099] In this embodiment, the rear end cover 321 is in a groove shape. An edge protruding radially outwards is provided at the notch of the rear end cover 321. The second limit cover 322 is sleeved on the rear ends of the rear end cover 321 and the rear housing 32. The claw 943 on the second limit cover 322 is engaged with the slot 312 on the rear housing 32 to realize the installation of the rear end cover 321.

[0100] In this embodiment, a circuit board is provided on the inner side of the bottom of the groove of the rear end cover 321. The circuit board is electrically connected to the power module of the spotlight. A power supply module is also installed on the bottom of the groove of the rear end cover 321. The power supply module is electrically connected to the circuit board. The power supply module is connected to an external circuit in a magnetic adsorption power supply mode.

[0101] A display screen is also provided on the inner side of the bottom of the groove of the rear end cover 321. The display screen can specifically be a liquid crystal screen. A light-transmitting area is provided on the bottom of the groove of the rear end cover 321. The light-transmitting area corresponds to at least the display screen. The light-transmitting area can be a glass plate embedded in the rear end cover 321, and a sealant can be filled between the two, and it is necessary to ensure sealing with the rear end cover 321.

[0102] A waterproof button is also provided on the bottom of the groove of the rear end cover 321. The waterproof button is electrically connected to the circuit board, and the user can control the spotlight through the waterproof button.

[0103] In this embodiment, a stepped section with an outer diameter increasing from the rear to the front is provided at the rear end of the rear housing 32. The stepped section is inserted into the second axially extending portion, and the inner shape of the second axially extending portion is the same as the outer shape of the rear end of the rear housing 32. Thus, it is convenient to install the second limiting cover 322.

[0104] Preferably, in this embodiment, a plurality of claw 943 arranged circumferentially are provided on the second axially extending portion, and a gap is provided between adjacent two claws 943.

[0152] Of course, the spotlight can also be configured with both an internal power module and an external power module. In this case, the external power module is equivalent to a backup power supply for the spotlight. When long-term use is required, the external power module can be used to supply power to the spotlight. When the radiator 1 of the spotlight is liquid-cooled, the external power module can also supply power to the pump 18 at the same time.

[0156] In this embodiment, when an internal power module is provided in the rear housing 32, the axial length of the rear housing 32 is increased, thereby increasing the accommodation space of the rear housing 32.

[0157] If no internal power module is provided in the rear housing 32, the axial dimension of the rear housing 32 can be appropriately shortened to make the spotlight more portable. When the spotlight is in use, it can be powered by an external external power module.

[0166] Embodiment III

[0167] As Figures 1 to 15 shown, in the embodiment of the present utility model, a radiator 1 for a spotlight is introduced, which includes 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 is arranged around the first cylindrical portion 101. There is a gap between the outer wall of the first cylindrical portion 101 and the inner wall of 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 there are multiple fins 103 arranged at intervals along the circumferential direction of the profile 100.

[0168] In this embodiment, the first cylindrical portion 101 and the second cylindrical portion 102 can be coaxially arranged or non-coaxially arranged.

[0169] The width direction of the fin 103 can extend along the radial direction of the profile 100 or can be arranged at an angle relative to the radial direction of the profile 100. When the width direction of the fin 103 is arranged at an angle relative to the radial direction of the profile 100, each fin 103 inclines towards the same side of the radial direction of the profile 100.

[0170] The length direction of the fin 103 can extend along the axial direction of the profile 100 or can be arranged at an angle relative to the axial direction of the profile 100. When the length direction of the fin 103 is arranged at an angle relative 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.

[0171] That is, in this embodiment, the extending paths of the sides of the respective fin plates 103 close to the axis of the profile 100 on the first cylindrical portion 101 are parallel to each other, and the extending paths of the sides of the respective fin plates 103 away from the axis of the profile 100 on the second cylindrical portion 102 are parallel to each other. That is, if the profile 100 is unfolded into a plane, the respective fin plates 103 are parallel to each other.

[0172] Preferably, in this embodiment, the plurality of fin plates 103 are arranged evenly in the circumferential direction of the profile 100.

[0173] Preferably, in this embodiment, taking the first cylindrical portion 101 and the second cylindrical portion 102 being coaxial, the width direction of the fin plate 103 extending along the radial direction of the profile 100, and the length direction of the fin plate 103 extending along the axial direction of the profile 100 as an example for description.

[0174] As Figure 3 、 4 shown, in this embodiment, the spotlight further includes a housing, and the housing 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.

[0175] In this embodiment, by providing an opening 10 on the first cylindrical portion 101 and / or the second cylindrical portion 102, the cooling medium is allowed to flow between the first cylindrical portion 101 and the second cylindrical portion 102 and / or inside the first cylindrical portion 101 to achieve heat dissipation.

[0176] In this embodiment, the cooling medium includes air flow and coolant.

[0177] 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;

[0178] Or, 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.

[0179] In this embodiment, the light energy module 2 is disposed inside the first cylindrical portion 101.

[0180] When the opening 10 is provided on the first cylindrical portion 101, if the cooling medium is air flow, it can directly flow inside the first cylindrical portion 101; if the cooling medium is coolant, it needs to flow inside the first cylindrical portion 101 through a pipeline.

[0181] As Figures 1 to 6As shown, in some possible embodiments, the radiator 1 dissipates heat naturally. By cutting the profile 100, the contact area between the profile 100 and the external air is increased, allowing the air flow to circulate naturally between the inside and the outside of the profile 100 to ensure a high heat dissipation efficiency.

[0182] 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.

[0183] Specifically, in this embodiment, the opening 10 is provided on the second cylindrical portion 102 and extends circumferentially along the second cylindrical portion 102. Thus, the side of the fin 103 away from the axis of the profile 100 is exposed, and the external air can contact the internal fin 103 and the first cylindrical portion 101 through the opening 10, improving the heat dissipation efficiency.

[0184] In this embodiment, the opening 10 can be provided in the middle of the second cylindrical portion 102 or at the end of the second cylindrical portion 102. It is also possible to cut the entire second cylindrical portion 102 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.

[0185] In this embodiment, the opening 10 can be provided as one, provided on the second cylindrical portion 102, and 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 with a plurality of openings arranged at intervals along the axis of the second cylindrical portion 102.

[0186] Specifically, when the opening 10 is provided in the middle of the second cylindrical portion 102, the front housing 31 and the rear housing 32 of the spotlight are connected to the end 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 the rear housing 32 of the spotlight are connected to the end of the first cylindrical portion 101.

[0187] Preferably, in this embodiment, when the diameter of the spotlight is relatively large, in order to ensure the assembly effect with the front housing 31 and the rear housing 32, the opening 10 can be provided in the middle of the second cylindrical portion 102, and the front housing 31 and the rear housing 32 are respectively connected to the ends of the first cylindrical portion 101 and the second cylindrical portion 102.

[0188] Alternatively, the opening 10 can be provided both on the second cylindrical portion 102 and on the first cylindrical portion 101.

[0189] Specifically, in this embodiment, at least one opening 10 is provided on each of the first cylindrical portion 101 and the second cylindrical portion 102, and the opening 10 extends circumferentially along the first cylindrical portion 101 or the second cylindrical portion 102.

[0190] 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.

[0191] In this embodiment, when the floodlight has a high requirement for waterproof performance, the opening 10 is provided only on the second cylindrical portion 102 and not on the first cylindrical portion 101. The front housing 31 and the rear housing 32 of the floodlight are respectively hermetically connected to the front and rear ends of the first cylindrical portion 101 of the profile 100, thereby preventing water from entering the interior of the floodlight. Specifically, the front housing 31 and the rear housing 32 of the floodlight are respectively inserted into the front and rear ends of the first cylindrical portion 101, and a sealing ring 5 is provided at the overlapping portion to ensure the assembly effect and the sealing effect.

[0192] As Figures 7 to 11 shown, in some possible embodiments, the radiator 1 is air-cooled. The radiator 1 includes a blower 14. By cutting the profile 100, an opening 10 is formed on the second cylindrical portion 102, or openings 10 are formed on the first cylindrical portion 101 and the second cylindrical portion 102, so that air flow circulates between the interior and the exterior of the profile 100 to improve the heat dissipation effect.

[0193] In this embodiment, the blower 14 can be provided inside the profile 100 or outside the profile 100.

[0194] Preferably, in this embodiment, the opening 10 includes an air inlet 11 and an air outlet 12 provided on the second cylindrical portion 102, and a circulation port 13 provided on the first cylindrical portion 101; the blower 14 is provided on the inner circumference of the first cylindrical portion 101 and is used to drive air flow to circulate between the first cylindrical portion 101 and the second cylindrical portion 102 and inside the first cylindrical portion 101.

[0195] Specifically, in this embodiment, a mounting plate 6 is provided inside the first cylindrical portion 101. The mounting plate 6 divides the internal space of the first cylindrical portion 101 into a first circulation chamber and a second circulation chamber. The circulation port 13 corresponds to the first circulation chamber, and the blower 14 is installed in the first circulation chamber.

[0196] In this embodiment, the circulation port 13 extends along the circumferential direction of the first cylindrical portion 101. The outlet end of the blower 14 is disposed opposite to the circulation port 13, and the air outlet 12 on the first cylindrical portion 101 corresponds to the outlet end of the blower 14. During the operation of the blower 14, external air is inhaled from the air inlet 11 between the first cylindrical portion 101 and the second cylindrical portion 102, circulates between the first cylindrical portion 101 and the second cylindrical portion 102, in the first circulation chamber and the second circulation chamber, and then is discharged from the air outlet 12.

[0197] Preferably, in this embodiment, the air outlet 12 is arranged as an arc extending along the circumferential direction of the second cylindrical part 102. The two ends of the air outlet 12 extending along the circumferential direction of the second cylindrical part 102 correspond to the sides of the fin plates 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 along the circumferential direction of the second cylindrical part 102 correspond to the sides of the fin plates 103 in the same range close to the axis of the profile 100. The air inlet 11 is arranged on the side of the air outlet 12 close to the second circulation cavity.

[0199] Thus, during the operation of the fan 14, after the air flow enters the space between the first cylindrical part 101 and the second cylindrical part 102 from the air inlet 11, it flows away from the air outlet 12 between the fin plates 103 in the area covered by the air inlet 11 in the circumferential direction of the profile 100, and then flows into the first circulation cavity through the fin plates 103 in the area not covered by the air inlet 11 in the circumferential direction of the profile 100, and enters the first circulation cavity through the part of the circulation port 13 not covered by the outlet end of the fan 14.

[0200] After the air flow enters the first circulation cavity, it is discharged to the outside of the profile 100 through the fan 14 and the air outlet 12. Thus, the overall profile 100 has a high heat dissipation effect.

[0201] Preferably, in this embodiment, during the discharge process of the air flow, part of the air flow can flow through the fin plates 103 in the area covered by the air outlet 12 in the circumferential direction of the profile 100 to both sides of the air outlet 12.

The annular channels 4 are correspondingly arranged with the space between the first cylindrical part 101 and the second cylindrical part 102, and the annular channels 4 are used to communicate with the spaces between adjacent two partition plates.

[0205] The circulating air flow enters the annular channel 4 on one side of the second circulation cavity from the air inlet 11, passes through the annular channel 4 and enters the space between the fin plates 103 in the area not covered by the air inlet 11 in the circumferential direction of the profile 100, and then enters the annular channel 4 on one side of the first circulation cavity. It enters the first circulation cavity through this annular channel 4 and the circulation port 13.

[0206] 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 part 102 at the bottom of the second cylindrical part 102. Thus, 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 spray waterproofing.

[0207] In this embodiment, at least the two ends of the first cylindrical part 101 are inserted into the front housing 31 and the rear housing 32, and a sealing ring 5 is arranged at the insertion position.

[0208] As Figures 12 to 14 shown, in some possible embodiments, the radiator 1 is liquid-cooled. The radiator 1 includes a pump 18. By machining the profile 100, an opening 10 is formed on the second cylindrical part 102, or openings 10 are formed on the first cylindrical part 101 and the second cylindrical part 102, so that the coolant circulates between the inside and the outside of the profile 100 to improve the heat dissipation effect.

[0209] In this embodiment, if it is set that the coolant circulates inside the first cylindrical part 101, a pipeline for the coolant to circulate needs to be arranged inside the profile 100.

[0213] Specifically, annular channels 4 are arranged between the two ends of the profile 100 and the front housing 31 and the rear housing 32 respectively. The annular channels 4 are arranged corresponding to the space between the first cylindrical part 101 and the second cylindrical part 102, and the annular channels 4 are used to communicate with the spaces between each adjacent two partitions.

[0214] The pump 18 is arranged between the liquid inlet 15 and the liquid storage structure. The pump 18 sucks the coolant in the liquid storage structure, fills the coolant into the profile 100. 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 output from the liquid outlet 16 and discharged into the liquid storage structure.

[0215] Specifically, after the coolant fills the space between the first cylindrical part 101 and the second cylindrical part 102 of the profile 100, the circulation mode is that it is filled into the annular channel 4 on the side close to the liquid inlet 15 from the liquid inlet 15, then flows into the annular channel 4 on the side close to the liquid outlet 16 through the space between two adjacent wing plates 103 not corresponding to the liquid inlet 15, and then converges into the space between two adjacent wing plates 103 corresponding to the liquid outlet 16 through this annular channel 4, and flows out of the profile 100 from the liquid outlet 16.

[0216] In this embodiment, the liquid storage structure can be provided separately by the manufacturer. For example, a water tank fitting adapted to the spotlight is designed to facilitate the user to carry. Of course, the liquid storage structure can also be prepared by the user himself. For example, the water storage structure can be a water bucket, a kettle, etc.

[0217] Preferably, in this embodiment, the pump is installed outside the second cylindrical part.

[0220] Specifically, the first part 171 is tubular. One end of the first part 171 is threadedly connected to the liquid inlet 15 or the liquid outlet 16, and the other end protrudes from the outer surface of the profile 100. One end of the second part 172 is sleeved on the other end of the first part 171, and the other end of the second part 172 is inserted into the external pipeline.

[0221] Preferably, in this embodiment, the second parts 172 of the connectors 17 on the liquid inlet 15 and the liquid outlet 16 are connected as a whole and are installed on the second cylindrical part 102 of the profile 100 through screws, so as to ensure the installation stability of the connector 17.

[0222] In this embodiment, a radial protrusion is provided in the middle of the first part 171. An operator can tighten the first part 171 of the joint 17 onto the profile 100 through the radial protrusion.

[0223] 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.

[0224] Preferably, in this embodiment, one end of the second part 172 away from the first part 171 extends along the axial direction of the profile 100. The ends of the second part 172 of the joint 17 at the liquid inlet 15 and the liquid outlet 16 extend in directions away from each other. A protective cover is further provided outside the radiator 1 for partially hiding the joint 17 inside the protective cover. External pipelines are connected to the joint 17 at the liquid inlet 15 and the liquid outlet 16 through through-holes at both ends of the protective cover.

[0225] In this embodiment, the annular channel 4 in the spotlight of the radiator 1 using the air-cooling method and the radiator 1 using the liquid-cooling method is formed by splicing and combining the front housing 31, the rear housing 32 and the profile 100.

[0226] Specifically, the front housing 31 and the rear housing 32 are respectively inserted and matched with the front and rear ends of the profile 100.

[0227] As Figure 15As shown, the outer diameter of the first insertion part 33 is smaller than that of the second insertion part 34. The first insertion part 33 protrudes at least partially axially from the end face of the second insertion part 34. The end of the second insertion part 34 and the root of the first insertion part 33 are connected by an extension wall 35 extending radially. Specifically, the end of the second cylindrical part 102 of the profile 100 protrudes at least partially outward relative to the end of the wing plate 103. One end of the front housing 31 or the rear housing 32 that cooperates with the profile 100 is provided with a second insertion part 34 adapted to the inner diameter of the second cylindrical part 102. The end of the second insertion part 34 is provided with an extension wall 35 extending radially towards the axis of the profile 100.

The sealing ring 5 is sleeved on the first insertion part 33 and the second insertion part 34 and is limitedly installed in the fitting grooves 36 on the first insertion part 33 and the second insertion part 34. When the first insertion part 33 and the second insertion part 34 are inserted into the first cylindrical part 101 and the second cylindrical part 102, the sealing ring 5 elastically abuts against the bottom of the fitting groove 36 and the inner walls of the first cylindrical part 101 and the second cylindrical part 102 to seal 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.

[0229] Preferably, as Figure 7 , Figure 8 and Figure 13 shown, in this embodiment, at least part of the end of the wing plate 103 is spaced from the extension wall 35, thereby forming an annular channel 4 with the extension wall 35.

[0230] In some specific embodiments, the end of the first cylindrical part 101 abuts against the extension wall 35, and at least part of the end of the wing plate 103 extends obliquely towards the middle of the profile 100.

[0231] Preferably, in this embodiment, at least part of the two ends of the wing plate 103 extending axially along the profile 100 extends obliquely towards the middle of the profile 100 in the direction close to the axis of the profile 100 or in the direction away from the axis of the profile 100.

[0232] 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.

Moreover, at least part of both ends of the fin 103 extends obliquely toward the middle of the profile 100 in the direction close to the axis of the profile 100, forming a gap with the extension wall 35.

[0233] In some specific embodiments, the radiator 1 with a smaller size using natural heat dissipation is suitable for dissipating heat from a spotlight with a power of 5W to 10W, the radiator 1 with a larger size using natural heat dissipation is suitable for dissipating heat from a spotlight with a power of 10W to 15W, the radiator 1 using air-cooled heat dissipation is suitable for dissipating heat from a spotlight with a power of 15W to 25W, and the radiator 1 using liquid-cooled heat dissipation is suitable for dissipating heat from a spotlight with a power of 25W to 40W.

[0234] In this embodiment, by setting that the radiator 1 is made of a profile 100, the profile 100 includes a first cylindrical portion 101, a second cylindrical portion 102 and fins 103 connected between the two, so that production personnel can set openings 10 at different positions on the profile 100 to make the profile 100 suitable for different heat dissipation methods. That is, after the profile 100 is obtained by one-time mold opening, different forms of radiators 1 are produced by performing subsequent cutting processing on the profile 100. Thus, the production cost of the radiator 1 is reduced, and the production efficiency of the radiator 1 is improved. In addition, since the radiator 1 is made of a profile 100, the radiator 1 can be suitable for being separately replaced on different spotlights during later use. Users can separately purchase the radiator 1 to combine spotlights with different powers, which is beneficial to saving the use cost for users.

[0242] Alternatively, an internal power module is provided inside the rear housing 32, and an external power module is provided outside the spotlight.

[0243] In this embodiment, since the wires, the control module 8, and the internal power module 7 are mainly concentrated on the rear housing 32, the light energy module 2 can be installed on the mounting plate 6 first, connected to the control module 8 and the internal power module 7 on the rear housing 32 through wires, and then the mounting plate 6 is installed on the rear housing 32 and fixed by screws to adjust the distance between the rear housing 32 and the mounting plate 6. When installing the radiator 1, the radiator 1 is sleeved on the outer periphery of the mounting plate 6 and fixedly sleeved with the end of the rear housing 32. At this time, the mounting plate 6 abuts against the limiting portion 104 on the inner periphery of the radiator 1. Then, the front housing 31 is inserted into one end of the radiator 1 away from the rear housing 32, and the front housing 31 is fixed to the mounting plate 6 by screws. At this time, the front housing 31, the radiator 1, and the rear housing 32 are integrated. Finally, the lens 9 is installed on the front housing 31.
