Description

Technical Field

[0001] The utility model belongs to the technical field of lighting equipment, and particularly relates to a radiator for a spotlight, and also relates to a spotlight equipped with the radiator for a spotlight. Background Art

[0002] The name of "spotlight" is a newly named term for the application of high-power LED lights in this research. There are many actual market products, such as high-intensity flashlights, fishing lights, laser cannons, photography fill lights, and so on. The main purpose is to meet the application requirements of light brightness, illumination range, lighting distance, and light color in various scenarios.

[0003] In use, the lamp housing of the existing technology has a very high temperature, and its heat dissipation mainly occurs through the heat exchange between the surface of the lamp housing and the external air. Tungsten halogen lamps and metal halide lamps can withstand relatively high working temperatures, but LEDs cannot work at high temperatures. Therefore, the LED spotlight must solve the problem of heat dissipation.

[0004] The existing heat dissipation methods are generally as follows:

[0005] 1. Increase the contact area between the housing and the air to improve the heat dissipation efficiency. For example: The Chinese invention patent with the application number CN201910737524.1 discloses a self-cooling LED spotlight, which increases the contact area with the external air by setting heat dissipation fins, thereby enhancing the heat dissipation effect.

[0006] 2. Set a fan inside the lamp housing of the spotlight to accelerate the air convection. For example: The Chinese utility model patent with the application number CN201220230238.X discloses an LED spotlight, which circulates the air inside and outside the radiator by setting a fan in the box-shaped heat dissipation device, thereby enhancing the heat dissipation effect.

[0007] 3. Utilize the coolant to circulate inside the housing to improve the heat dissipation efficiency. For example: The Chinese invention patent with the application number CN201910737536.4 discloses a convection liquid-cooled LED lamp, which uses the coolant to dissipate heat from the lamp.

[0008] However, when manufacturing spotlights using different heat dissipation methods, separate molds need to be opened during the production process, resulting in high production costs and low production efficiency.

[0009] Therefore, designing a radiator that can reduce production costs and improve production efficiency has become a technical problem that needs to be urgently solved by those skilled in the art.

[0010] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0075] Embodiment 1

[0076] 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. 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 a plurality of fins 103 are arranged at intervals along the circumferential direction of the profile 100.

[0077] In this embodiment, the first cylindrical portion 101 and the second cylindrical portion 102 can be coaxially arranged or non-coaxially arranged.

[0078] 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 in the radial direction of the profile 100.

[0079] The length direction of the fin 103 can be 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 to the axial direction of the profile 100, the angles between each fin 103 and the axis of the profile 100 are the same.

[0080] That is, in this embodiment, the extending paths of the sides of each fin 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 each fin 103 far 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, each fin 103 is parallel to each other.

[0081] Preferably, in this embodiment, a plurality of the fins 103 are evenly arranged along the circumferential direction of the profile 100.

[0082] Preferably, in this embodiment, taking the first cylindrical portion 101 and the second cylindrical portion 102 being coaxial, the width direction of the fin 103 extending along the radial direction of the profile 100, and the length direction of the fin 103 extending along the axial direction of the profile 100 as an example for description.

[0083] 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.

[0084] In this embodiment, by providing an opening 10 on the first cylindrical portion 101 and / or the second cylindrical portion 102, the cooling medium flows between the first cylindrical portion 101 and the second cylindrical portion 102 and / or inside the first cylindrical portion 101 to achieve heat dissipation.

[0085] In this embodiment, the cooling medium includes air flow and coolant.

[0086] 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;

[0087] 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.

[0088] In this embodiment, the light energy module 2 is arranged inside the first cylindrical portion 101.

[0089] When an opening 10 is provided on the first cylindrical portion 101, if the cooling medium is an air flow, it can directly flow inside the first cylindrical portion 101; if the cooling medium is a coolant, it needs to flow inside the first cylindrical portion 101 through a pipeline.

[0090] As Figures 1 to 6 shown, in some possible embodiments, the radiator 1 dissipates heat naturally. By machining the profile 100, the contact area between the profile 100 and the external air is increased, enabling the air flow to naturally circulate between the inside and the outside of the profile 100 to ensure a high heat dissipation efficiency.

[0091] 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.

[0092] Specifically, in this embodiment, the opening 10 is provided on the second cylindrical portion 102 and extends along the circumferential direction of 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.

[0093] 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. The second cylindrical portion 102 can also be machined 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.

[0094] 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 axial direction of the second cylindrical portion 102.

[0095] 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.

[0096] Preferably, in this embodiment, when the diameter of the spotlight is relatively large, 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.

[0097] Alternatively, the opening 10 can be provided on both the second cylindrical portion 102 and the first cylindrical portion 101.

[0098] 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 along the circumferential direction of the first cylindrical portion 101 or the second cylindrical portion 102.

[0099] 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.

[0100] In this embodiment, when the floodlight has a high requirement for waterproof performance, the opening 10 is only provided 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.

[0101] As Figures 7 to 11 shown, in some possible embodiments, the radiator 1 is air-cooled. The radiator 1 includes a fan 14. By machining the profile 100, an opening 10 is formed on the second cylindrical portion 102, or openings 10 are formed on both the first cylindrical portion 101 and the second cylindrical portion 102, so that the air flow circulates between the interior and the exterior of the profile 100 to improve the heat dissipation effect.

[0102] In this embodiment, the fan 14 can be provided inside the profile 100 or outside the profile 100.

[0103] 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 fan 14 is provided on the inner circumference of the first cylindrical portion 101 and is used to drive the air flow to circulate between the first cylindrical portion 101 and the second cylindrical portion 102 and inside the first cylindrical portion 101.

[0104] Specifically, in this embodiment, a mounting plate 6 is provided inside the first cylindrical portion 101, and 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 fan 14 is installed in the first circulation chamber.

[0105] In this embodiment, the circulation port 13 extends along the circumferential direction of the first cylindrical portion 101. The outlet end of the fan 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 fan 14. During the operation of the fan 14, external air is sucked into the space between the first cylindrical portion 101 and the second cylindrical portion 102 from the air inlet 11, circulates in the space between the first cylindrical portion 101 and the second cylindrical portion 102, the first circulation chamber and the second circulation chamber, and is discharged from the air outlet 12.

[0106] Preferably, in this embodiment, the air outlet 12 is arranged as an arc extending along the circumferential direction of the second cylindrical portion 102. The two ends of the air outlet 12 extending along the circumferential direction of the second cylindrical portion 102 correspond to the sides of the fin plates 103 in the first range away from the axis of the profile 100, and the two ends of the outlet end of the fan 14 extending along the circumferential direction of the second cylindrical portion 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 chamber.

[0107] 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.

[0108] Thus, during the operation of the fan 14, after the air flow enters the space between the first cylindrical portion 101 and the second cylindrical portion 102 from the air inlet 11, it flows toward the side 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 chamber 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 chamber through the part of the circulation port 13 not covered by the outlet end of the fan 14.

[0109] After the air flow enters the first circulation chamber, 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.

[0110] 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.

[0111] 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°. Further 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°.

[0112] Preferably, in this embodiment, the fan 14 is a volute fan 14, and the fan 14 is installed on the mounting plate 6.

[0113] In this embodiment, an annular channel 4 is formed between the two ends of the profile 100 and the front housing 31 and the rear housing 32 respectively. The annular channel 4 is correspondingly arranged with the space between the first cylindrical part 101 and the second cylindrical part 102, and the annular channel 4 is used to communicate with the space between each adjacent two partitions.

[0114] The circulating air flow enters the annular channel 4 on one side of the second circulation cavity from the air inlet 11, enters between the fin plates 103 in the area not covered by the air inlet 11 in the circumferential direction of the profile 100 through the annular channel 4, then enters the annular channel 4 on one side of the first circulation cavity, and enters the first circulation cavity through this annular channel 4 and the circulation port 13.

[0115] 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.

[0116] 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.

[0117] As Figures 12 to 14 shown, in some possible embodiments, the radiator 1 is liquid-cooled. The radiator 1 includes a pump 18. By cutting 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.

[0118] In this embodiment, if the coolant is set to flow inside the first cylindrical part 101, a pipeline for the coolant to flow through needs to be arranged inside the profile 100.

[0119] Preferably, in this embodiment, the coolant does not enter the inside of the first cylindrical part 101.

[0123] 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 and fills the coolant into the profile 100. After the coolant fills the space between the first cylindrical portion 101 and the second cylindrical portion 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.

[0124] Specifically, after the coolant fills the space between the first cylindrical portion 101 and the second cylindrical portion 102 of the profile 100, the coolant circulates in the following manner: it is filled into the annular channel 4 near the liquid inlet 15 from the liquid inlet 15, and then flows into the annular channel 4 near the liquid outlet 16 through the space between the two adjacent fin plates 103 that do not correspond to the liquid inlet 15, and then flows into the space between the two adjacent fin plates 103 corresponding to the liquid outlet 16 through the annular channel 4, and flows out of the profile 100 from the liquid outlet 16.

[0125] In this embodiment, the liquid storage structure can be provided separately by the manufacturer, for example, a water tank accessory 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 bucket, a kettle, etc.

[0126] Preferably, in this embodiment, the pump is installed outside the second cylindrical portion.

[0127] Preferably, in this embodiment, the liquid inlet 15 and the liquid outlet 16 are arranged in parallel along the axial direction of the profile 100 and are correspondingly connected to the space between the same two adjacent fin plates 103 .

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 plugged into an external pipeline.

[0130] 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 by screws, so as to ensure the installation stability of the connector 17.

[0131] 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 on the profile 100 through the radial protrusion.

[0132] Preferably, in this embodiment, a sealing ring 5 is provided at the connection between the radial protrusion and the first part 171, and the radial protrusion presses the sealing ring 5 against the profile 100 to ensure the sealing effect at the liquid inlet 15 and the liquid outlet 16.

[0133] Preferably, in this embodiment, the end of the second part 172 away from the first part 171 extends along the axial direction of the profile 100, and the ends of the second parts 172 of the connectors 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 hiding part of the connector 17 inside the protective cover. External pipelines are connected to the connectors 17 at the liquid inlet 15 and the liquid outlet 16 through through holes at both ends of the protective cover.

[0136] 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, at least part of the end of the second cylindrical part 102 of the profile 100 protrudes 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. When the second insertion part 34 is inserted into the second cylindrical part 102, the extension wall 35 abuts against the end of the wing plate 103 and / or the end of the first cylindrical part 101. The first insertion part 33 extending into the first cylindrical part 101 and adapted to be inserted and mated with the end of the first cylindrical part 101 is provided on the extension wall 35.

[0137] Preferably, in this embodiment, fitting grooves 36 extending circumferentially along the profile 100 are respectively provided on the part where the first insertion part 33 overlaps with the first cylindrical part 101 and on the part where the second insertion part 34 overlaps with the second cylindrical part 102. The sealing ring 5 is sleeved on the first insertion part 33 and the second insertion part 34 and is limited and 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, so as 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.

[0138] 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, so as to form an annular channel 4 therebetween.

[0139] 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.

[0140] Preferably, in this embodiment, at least part of the two ends of the wing plate 103 extending axially along the profile 100 extend 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.

[0141] 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 a 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. 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.

[0142] 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.

[0143] In this embodiment, by providing 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 connecting the two, 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 through subsequent cutting processing of 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 separate replacement on different spotlights during later use. Users can purchase the radiator 1 separately to combine spotlights with different powers, which is beneficial for saving the usage cost for users.

[0144] In this embodiment, when the front housing 31 and the rear housing 32 of the spotlight are installed on the profile 100, the front housing 31 and the rear housing 32 are respectively connected to the mounting plate 6 in the middle of the profile 100 through a screw structure.

A limiting portion 104 protruding and extending toward the inside of the first cylindrical portion 101 is provided on the inner wall of the first cylindrical portion 101. The mounting plate 6 is installed in the first cylindrical portion 101 and abuts against the limiting portion 104, and is connected to the front housing 31 and the rear housing 32 through screws.

[0146] Specifically, in this embodiment, the mounting plate 6 is installed in the first cylindrical portion 101 at one end where the profile 100 is connected to the rear housing 32. First, the front housing 31 is connected to the mounting plate 6 by screws, so that the radiator 1, the mounting plate 6, and the front housing 31 are integrated.

[0151] Alternatively, an internal power module is provided inside the rear housing 32, and an external power module is provided outside the spotlight.

[0152] 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 first installed on the mounting plate 6, 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.

[0192] When the spotlight is liquid-cooled, the built-in power module is electrically connected to an external pump 18 through the power supply module to supply power to the pump 18.

[0193] The power module can only include an external power module. The external power module is a separately provided mobile power supply. The external power module can supply power to the light collector through the power supply module. Of course, the external power module can also be used to supply power to the pump 18 of the radiator 1 using the liquid-cooling method.

[0194] 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 serves as a backup power supply for the spotlight. When long-term use is required, the external power module can supply power to the spotlight.

[0198] In this embodiment, when an internal power module is provided in the rear housing 32, the axial length of the rear housing 32 is lengthened, thereby increasing the accommodation space of the rear housing 32.

[0199] 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.

[0200] In some specific embodiments, the rear housing 32 includes a rear housing main body and a rear end cover. The rear end cover is provided at the rear end of the rear housing main body, and the front end of the rear housing main body is used to connect to the rear end of the radiator 1.

[0201] Preferably, in this embodiment, a sealing structure is provided between the rear end cover and the rear housing main body.

[0202] In this embodiment, by providing a sealing structure between the lens 9 and the front housing main body, a sealing structure between the rear end cover and the rear housing main body, a sealing structure between the front housing main body and the radiator 1, a sealing structure between the rear housing main body and the rear end of the radiator 1, and hiding the screws inside the spotlight, the overall sealing performance of the product can be improved to reach the immersion waterproof level.

[0203] Among them, the spotlight using air-cooled heat dissipation can only reach the spray waterproof level because a circulation port 13 is provided on the first cylindrical portion 101.

[0204] Preferably, in this embodiment, the profile 100 of the radiator 1 is an aluminum profile 100, and both the front housing 31 and the rear housing 32 are made of lightweight materials, so that the overall density is low. Even in the case of falling into water, it can float on the water surface, making it easy to find. This enables the product to be applicable to various usage scenarios.

[0205] Preferably, in this embodiment, a base is further provided on the spotlight. The base is arranged at the bottom of the radiator 1 and is used to support the spotlight to ensure that the spotlight can be stably placed.

[0206] Preferably, in this embodiment, the base can also be set as a structure with an adjustable angle, so that the inclination angle of the spotlight can be changed.

[0207] Preferably, in this embodiment, a handle is further provided on the spotlight. The handle is arranged at the top of the radiator 1, which is convenient for users to move the spotlight.

[0208] Embodiment III

[0209] As Figures 16 to 20 shown, in the embodiment of the present invention, 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, it can ensure that the spotlight will not be damaged when the spotlight accidentally falls into water.

[0210] 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.

[0211] 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. Different lenses 9 can be switched and / or the lens 9 can be focused according to different usage scenarios.

[0212] In this embodiment, the front housing 31 is set as 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, and a first sealing structure 93 is provided at the overlapping portion of the lens 9 and the front housing 31.

[0213] 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 is elastically abutted against the lens 9, and the outer circumference is elastically abutted against the front housing 31. By arranging 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.

[0214] Preferably, in this embodiment, the lens 9 can axially move relative to the front housing 31, thereby adjusting the distance between the lens 9 and the light energy module 2 to achieve focusing.

[0215] In some specific embodiments, the lens 9 and the front housing 31 are in threaded engagement to adjust the distance between the lens 9 and the light energy module 2 inside the radiator 1. The user can also focus by screwing the lens 9.

[0216] In this embodiment, an annular groove 91 is provided on the outer peripheral wall of the lens 9. 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 first sealing ring on the gap between the lens 9 and the front housing 31. Additionally, it is possible to maintain or replace the first sealing ring when removing the lens 9, facilitating the disassembly and assembly of the first sealing ring.

[0217] 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.

[0218] 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 protrusion 311 corresponding to the threaded groove 92 is provided on the inner peripheral wall of the front housing 31, and the limiting protrusion 311 extends into the threaded groove 92 to cooperate with the threaded groove 92 to achieve the limitation of the lens 9.

[0219] Specifically, the thread groove 92 extends to the rear end of the lens 9. When the lens 9 is rotated, the limiting protrusion 311 can enter the thread 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 thread groove 92, and the limiting protrusion 311 abuts against the groove wall of the thread groove 92 to achieve axial limitation of the lens 9.

[0220] Preferably, in some possible embodiments, a plurality of the limiting protrusions 311 may be arranged at intervals along the circumferential direction of the front housing 31. The plurality of limiting protrusions 311 all correspond to the thread groove 92 in terms of spatial position, that is, the arrangement path of the plurality of limiting protrusions 311 is the same as the extension path of the thread groove 92.

[0221] Preferably, in this embodiment, the annular groove 91 is arranged on the front side of the thread groove 92. Thus, it is possible to avoid interference between the first sealing structure and the limiting protrusion 311 and ensure that the lens 9 can be disassembled and assembled smoothly.

[0222] Preferably, in some possible embodiments, a first limiting cover 94 for limiting the movement of the lens 9 is arranged at the front end of the front housing 31.

[0223] Specifically, as Figures 17 to 19 shown, the lens 9 includes a first section with an outer diameter the same as the inner diameter of the front housing 31, and a second section arranged 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 arranged opposite to the front end of the first section.

[0224] In this embodiment, the first section and the second section of the lens 9 are coaxially arranged, and the first sealing structure 93 is arranged between the first section and the front housing 31, that is, the thread groove 92 and the annular groove 91 are both arranged 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 to achieve 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.

[0225] 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 stop the lens 9.

[0226] 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.

[0227] In some preferred embodiments, the first radially extending portion 942 is spaced from the front end of the front housing 31, and the distance therebetween 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 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.

[0228] Preferably, the distance between the first radially extending portion 942 and the front end of the front housing 31 is slightly 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 section of the lens 9, and it is only necessary to ensure that the first sealing ring in the annular groove 91 does not move outside the front housing 31.

[0229] In some specific embodiments, the first limiting cover 94 is in snap-fit with the front housing 31.

[0230] 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 card slot 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 snapped into the card slot 312 of the front housing 31 to lock the relative position between the first limiting cover 94 and the front housing 31.

[0231] 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 internal shape of the first axially extending portion 941 is the same as the external 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.

[0232] 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 card slot 312, causing the claw 943 to undergo elastic deformation. When the claw portion moves to correspond to the card slot 312, the claw 943 rebounds and the claw portion is inserted into the card slot 312.

[0233] Preferably, in this embodiment, a plurality of claws 943 are arranged circumferentially, and a gap is provided between adjacent 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 aesthetics of the spotlight can be improved.

[0234] The inner circumference of the rear end of the jaw 943 is provided with an inclined surface that extends obliquely away from the axis of the first limit cover 94 along the installation direction of the first limit cover 94, that is, an inclined surface that extends obliquely away from the axis of the first limit cover 94 from front to back.

[0235] 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 the rear end of the rear housing 32 is provided with a rear end cover 321, and the rear end cover 321 can close the rear end of the rear housing 32.

[0236] Specifically, in this embodiment, at least a 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.

[0237] Preferably, the outer diameter of the front end of the rear end cover 321 is greater than the inner diameter of the rear housing 32. The front end of the rear end cover 321 is provided with an insertion section, and the outer diameter of the insertion section is the same as the inner diameter of the rear housing 32. The rear housing 32 is in insertion fit with the rear end of the rear housing 32 through the insertion section, and the second sealing structure 323 is provided between the insertion section and the rear housing 32.

[0238] Preferably, the second sealing structure 323 includes a second sealing ring provided on the insertion section. Specifically, an annular groove 91 is provided on the insertion section, and the second sealing ring is provided in the annular groove 91.

[0239] As Figure 20 shown, in this embodiment, the rear end of the rear housing 32 is provided with a second limit cover 322. 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 a 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.

[0240] 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 axis of the rear housing 32, and a second radially extending portion extending from the rear end of the second axially extending portion toward the axis of the rear housing 32.
