Description

Technical Field

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

[0002] The name of "spotlight" is a newly named term for the application of high-power LED lights in this study. 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, illumination distance, and light color in various scenarios.

[0003] In use, the lamp housing of the existing technology is very hot itself, and its heat dissipation is mainly carried out 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 a heat dissipation problem. Existing spotlights generally adopt natural heat dissipation, air-cooled heat dissipation or liquid-cooled heat dissipation.

[0004] Generally, an electrical energy module for supplying power to the light energy module, fan, and pump of the spotlight is built into the spotlight. However, generally, the capacity of the built-in electrical energy module of the spotlight is small, and it can only be applicable to conventional lighting time, and cannot be applicable to working conditions that require long-term lighting. Especially for high-power spotlights using air-cooled heat dissipation and liquid-cooled heat dissipation, they cannot be used for a long time. If a large-capacity built-in electrical energy module is uniformly configured for each spotlight, it is not conducive to controlling the cost of the spotlight, and the applicable working conditions of the spotlight will be limited.

[0005] In addition, for spotlights using liquid-cooled heat dissipation, the coolant needs to circulate inside and outside the spotlight, and an external liquid storage structure is required to store the coolant. Different working conditions have different requirements for the water tank supporting the spotlight. For example, some users who use spotlights near water sources have less need for a supporting water tank, while some indoor working conditions have a greater need for a supporting water tank. Existing spotlights using liquid-cooled heat dissipation are uniformly configured with water tanks, resulting in a higher cost of the spotlight, and affected by the capacity of the water tank, the spotlight cannot be applicable to working conditions that require long-term lighting.

[0006] Therefore, designing a fitting for a spotlight that can help reduce the cost of the spotlight and expand the applicable range of the spotlight has become a technical problem that needs to be solved urgently by those skilled in the art.

[0007] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0129] Embodiment Two

[0130] AsFigures 1 to 15 As shown, in an 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 arranged 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.

[0131] In this embodiment, the first cylindrical portion 101 and the second cylindrical portion 102 can be coaxially arranged or non - coaxially arranged.

[0132] 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.

[0133] 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 relative to the axial direction of the profile 100, the included angles between each fin 103 and the axis of the profile 100 are the same.

[0134] 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.

[0135] Preferably, in this embodiment, a plurality of the fins 103 are evenly arranged along the circumferential direction of the profile 100.

[0136] 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 illustration.

[0137] Such as Figure 3 、 4As shown, in this embodiment, the spotlight further includes a housing, which includes a front housing 31 and a rear housing 32. The front housing 31 and the rear housing 32 are respectively connected to the front and rear ends of the profile 100.

[0138] In this embodiment, by providing an opening 10 on the first cylindrical portion 101 and / or the second cylindrical portion 102, the cooling medium can 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.

[0139] In this embodiment, the cooling medium includes air flow and coolant.

[0140] 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.

[0141] 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.

[0142] In this embodiment, the light energy module 2 is disposed inside the first cylindrical portion 101.

[0143] 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.

[0144] As Figures 1 to 6 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, so that the air flow can naturally flow between the inside and the outside of the profile 100 to ensure a high heat dissipation efficiency.

[0145] 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.

[0146] 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 to improve the heat dissipation efficiency.

[0147] In this embodiment, the opening 10 can be arranged in the middle of the second cylindrical portion 102, or can be arranged at the end of the second cylindrical portion 102. It is also possible to integrally cut the 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.

[0148] In this embodiment, the opening 10 can be arranged as one, arranged 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, and a plurality of openings 10 arranged at intervals along the axial direction of the second cylindrical portion 102 can also be provided.

[0149] Specifically, when the opening 10 is arranged 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 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 the rear housing 32 of the spotlight are connected to the end of the first cylindrical portion 101.

[0150] Preferably, in this embodiment, when the diameter size 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 arranged 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.

[0151] Alternatively, the opening 10 can be arranged on both the second cylindrical portion 102 and the first cylindrical portion 101.

[0152] Specifically, in this embodiment, at least one opening 10 is respectively arranged on 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.

[0153] The openings 10 on the first cylindrical portion 101 and the second cylindrical portion 102 are preferably arranged in the middle of the first cylindrical portion 101 and the second cylindrical portion 102.

[0154] In this embodiment, when the spotlight has a relatively high requirement for waterproof performance, only the opening 10 is arranged on the second cylindrical portion 102, and no opening 10 is arranged on the first cylindrical portion 101. The front housing 31 and the rear housing 32 of the spotlight are respectively and hermetically connected to the front and rear ends of the first cylindrical portion 101 of the profile 100, thereby preventing water from entering the inside of the spotlight. Specifically, the front housing 31 and the 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 arranged at the overlapping part, thereby ensuring the assembly effect and the sealing effect.

[0155] Such as Figures 7 to 11As shown, in some possible embodiments, the radiator 1 is air-cooled. The radiator 1 includes a fan 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 flows circulates between the inside and the outside of the profile 100 to improve the heat dissipation effect.

[0156] In this embodiment, the fan 14 can be arranged inside the profile 100 or outside the profile 100.

[0157] 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 arranged 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.

[0158] Specifically, in this embodiment, a mounting plate 6 is arranged inside the first cylindrical portion 101. The mounting plate 6 divides the internal space of the first cylindrical portion 101 into a first circulation cavity and a second circulation cavity. The circulation port 13 corresponds to the first circulation cavity, and the fan 14 is installed in the first circulation cavity.

[0159] 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 arranged 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 between the first cylindrical portion 101 and the second cylindrical portion 102, in the first circulation cavity and the second circulation cavity, and then is discharged from the air outlet 12.

[0160] 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 side far from the axis of the profile 100 of the fin 103 within the first range, 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 side close to the axis of the profile 100 of the fin 103 within the same range. The air inlet 11 is arranged on the side of the air outlet 12 close to the second circulation cavity.

[0161] 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.

[0162] 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 towards 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 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.

[0163] 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.

[0164] Preferably, in this embodiment, during the discharge process of the air flow, part of the air flow can flow on both sides of the air outlet 12 between the fin plates 103 in the area covered by the air outlet 12 in the circumferential direction of the profile 100.

[0166] Preferably, in this embodiment, the fan 14 is a volute fan 14, and the fan 14 is installed on the mounting plate 6.

[0167] In this embodiment, annular channels 4 are respectively formed between the two ends of the profile 100 and the front housing 31 and the rear housing 32. 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.

[0168] The circulating air flow enters the annular channel 4 on one side of the second circulation cavity from the air inlet 11, enters 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.

[0169] 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.

[0170] 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.

[0171] like Figures 12 to 14 As shown, in some possible embodiments, the radiator 1 is liquid-cooled. The radiator 1 includes a pump 18, and the profile 100 is cut to form an opening 10 on the second cylindrical portion 102, or the first cylindrical portion 101 and the second cylindrical portion 102 are formed with openings 10, so that the coolant circulates between the inside and outside of the profile 100 to improve the heat dissipation effect.

[0172] In this embodiment, if the coolant is arranged to circulate inside the first cylindrical portion 101 , a pipeline for the coolant to circulate needs to be arranged inside the profile 100 .

[0175] Preferably, the liquid inlet 15 and the liquid outlet 16 correspond to the spaces between two different adjacent fins 103, respectively, and / or, the liquid inlet 15 and the liquid outlet 16 are arranged close to the top of the profile 100 to ensure that the coolant fills the space between the first cylindrical portion 101 and the second cylindrical portion 102 before circulating to the outside of the profile 100.

[0176] Specifically, an annular channel 4 is provided between the two ends of the profile 100 and the front shell 31 and the rear shell 32 respectively. The annular channel 4 is provided corresponding to the space between the first cylindrical portion 101 and the second cylindrical portion 102. The annular channel 4 is used to communicate with the space between each adjacent partition.

[0177] 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.

[0178] 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.

[0179] In this embodiment, the liquid storage structure can be provided separately by the manufacturer. For example, a water tank fitting adapted to the spotlight can be designed to facilitate the user's carrying. 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.

[0180] Preferably, in this embodiment, the pump is installed outside the second cylindrical portion.

[0181] 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 correspondingly communicated with the space between the same two adjacent wing plates 103.

[0182] Connectors 17 for connecting pipelines are respectively installed on the liquid inlet 15 and the liquid outlet 16. 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.

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.

[0184] 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 portion 102 of the profile 100 by screws, so as to ensure the installation stability of the connector 17.

[0185] 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.

[0186] 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 against the profile 100 to ensure the sealing effect at the liquid inlet 15 and the liquid outlet 16.

[0187] 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. 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 to hide part of the connector 17 inside the protective cover. The external pipeline is connected to the connectors 17 at the liquid inlet 15 and the liquid outlet 16 through the through holes at both ends of the protective cover.

[0188] 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.

[0189] 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. The front housing 31 and the rear housing 32 are respectively provided with a first insertion part 33 and a second insertion part 34 which are inserted and matched with 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 sealing rings 5 are arranged 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.

[0190] As Figure 15 shown, the outer diameter of the first insertion part 33 is smaller than the outer diameter of the second insertion part 34. The first insertion part 33 protrudes at least partially from the end face of the second insertion part 34 in the axial direction. 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 in the radial direction. Specifically, the end of the second cylindrical part 102 of the profile 100 protrudes at least partially outward relative to the end of the fin 103. One end of the front housing 31 or the rear housing 32 that is matched 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 in the direction close to the axis of the profile 100 in the radial direction. When the second insertion part 34 is inserted into the second cylindrical part 102, the extension wall 35 abuts against the end of the fin 103 and / or the end of the first cylindrical part 101, and the first insertion part 33 extending into the first cylindrical part 101 and inserted and matched with the end of the first cylindrical part 101 is arranged on the extension wall 35.

[0191] Preferably, in this embodiment, fitting grooves 36 extending in the circumferential direction of the profile 100 are respectively arranged on the overlapping parts of the first insertion part 33 and the first cylindrical part 101, and on the overlapping parts of the second insertion part 34 and 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, 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.

[0192] Preferably, as Figure 7 、Figure 8 and Figure 13 As shown in Figure 13 , in this embodiment, at least a part of the end of the fin 103 is spaced from the extension wall 35, so as to form an annular channel 4 between the fin 103 and the extension wall 35.

[0193] In some specific embodiments, the end of the first cylindrical portion 101 abuts against the extension wall 35, and at least a part of the end of the fin 103 extends obliquely toward the middle of the profile 100.

[0194] Preferably, in this embodiment, at least a part of the two ends of the fin 103 extending along the axial direction of the profile 100 extends obliquely toward 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.

[0195] Preferably, in this embodiment, the end of the fin 103 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 at least a part of the end of the fin 103 on the side away from the first cylindrical portion 101 abuts against the extension wall 35. Moreover, at least a part of the two 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, not only can the annular channel 4 be formed, but also the installation stability between the front housing 31 or the rear housing 32 and the profile 100 can be improved.

[0196] 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.

[0197] In this embodiment, by setting that the radiator 1 is made of a profile 100, the profile 100 includes a first cylindrical part 101, a second cylindrical part 102 and a fin 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 later 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 separately replaced on different spotlight lamps during later use, and users can separately purchase the radiator 1 to combine spotlight lamps with different powers, which is beneficial to saving the use cost for users.

[0198] In this embodiment, when the front housing 31 and the rear housing 32 of the spotlight lamp 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 screw structures.

[0238] In some specific embodiments, the front housing 31 includes a front housing main body and a lens 9 installed at the front end of the front housing main body. The rear end of the front housing main body is used to be connected to the front end of the radiator 1.

[0239] Preferably, a sealing structure is provided between the lens 9 and the front housing main body.

[0240] Specifically, the light energy module 2 of the spotlight is installed on one side of the mounting plate 6 facing the front housing 31 by screws. The operator can replace the bulb of the light energy module 2.

[0241] The built-in electrical energy module 7 of the spotlight can be provided inside the rear housing 32 or outside the spotlight.

[0242] Specifically, a built-in electrical energy module is provided inside the rear housing 32, which is electrically connected to the light energy module 2; and / or, a power supply module is provided on the rear housing 32, which is electrically connected to the light energy module 2 and / or the built-in electrical energy module and is used to connect to an external electrical energy module outside the rear housing 32; and / or, a control module 8, which is electrically connected to the light energy module 2 and is electrically connected to the built-in electrical energy module and / or the power supply module.

[0247] The power module may only include an external power module, which is a separately provided mobile power source. The external power module can supply power to the light collecting energy 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 a liquid cooling method.

[0248] Of course, the spotlight can also be configured 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 external power module can supply power to the spotlight.

When the magnetic head is inserted into the magnetic slot, it is attracted to the rear housing 32 and supplies power through induction with the power supply module. Thus, it is convenient for users to connect the circuit, and at the same time, the waterproof performance of the product can be further improved.

[0252] In this embodiment, when the built-in power module is disposed within the rear housing 32, the axial length of the rear housing 32 is extended, thereby increasing the accommodation space of the rear housing 32.

[0253] If no built-in power module is disposed within the rear housing 32, the axial dimension of the rear housing 32 can be appropriately shortened to make the spotlight more portable. When in use, the spotlight can be powered by an external external power module.

[0254] In some specific embodiments, the rear housing 32 includes a rear housing main body and a rear end cover. The rear end cover is disposed 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.

[0255] Preferably, in this embodiment, a sealing structure is provided between the rear end cover and the rear housing body.

[0257] 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.

[0258] 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 for easy searching. The product can be suitable for various usage scenarios.

[0259] 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.

[0260] 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.

[0261] 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.

[0262] Embodiment Four

[0263] 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.

[0264] 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.

[0265] 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.

[0266] In this embodiment, the front housing 31 is provided in a cylindrical shape, and 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.

[0267] 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 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.

[0268] 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.

[0269] 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 screwing the lens 9.

[0270] 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 first sealing ring on 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.

[0271] 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.

[0272] 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 and cooperates with the threaded groove 92 to limit the lens 9.

[0273] Specifically, the thread groove 92 extends to the rear end of the lens 9. By rotating the lens 9, the limit protrusion 311 can enter the thread groove 92 from the rear end of the lens 9. The shape of the limit protrusion 311 is the same as the inner shape of the thread groove 92, and the limit protrusion 311 abuts against the groove wall of the thread groove 92 to achieve axial limitation of the lens 9.

[0274] Preferably, in some possible embodiments, a plurality of the limit protrusions 311 may be arranged at intervals along the circumferential direction of the front housing 31. The plurality of limit protrusions 311 correspond to the thread groove 92 in terms of spatial position, that is, the arrangement path of the plurality of limit protrusions 311 is the same as the extension path of the thread groove 92.

[0275] Preferably, in this embodiment, the annular groove 91 is arranged on the front side of the thread groove 92. Thus, interference between the first sealing structure and the limit protrusion 311 can be avoided, ensuring that the lens 9 can be disassembled and assembled smoothly.

[0276] Preferably, in some possible embodiments, a first limit cover 94 for limiting the movement of the lens 9 is arranged at the front end of the front housing 31.

[0277] 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 limit cover 94 is arranged opposite to the front end of the first section.

[0278] 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 process of focusing 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 limit 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.

[0279] In some specific embodiments, the first limit 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 direction close to 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.

[0280] 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.

[0281] 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 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.

[0282] 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 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.

[0283] In some specific embodiments, the first limiting cover 94 and the front housing 31 are in snap-fit.

[0284] Specifically, at the rear end of the first axially extending portion 941, there is a claw 943 which 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. On the outer peripheral wall of the front housing 31, there is a card slot 312 corresponding to the claw portion of the claw 943. 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.

[0285] The front end of the front housing 31 is provided with a stepped section with an outer diameter increasing from front to back, and the stepped section is inserted into the first axially extending portion 941. 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.

[0286] 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 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 deform elastically. When the claw portion moves to correspond to the card slot 312, the claw 943 rebounds and the claw portion is embedded in the card slot 312.

[0287] Preferably, in this embodiment, a plurality of the claws 943 are arranged circumferentially, and a gap is provided between two adjacent claws 943, so that 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.

[0288] The inner circumference at the rear end of the claw 943 is provided with an inclined surface that extends obliquely 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 that extends obliquely away from the axis of the first limiting cover 94 from front to back.

[0289] In this embodiment, the rear housing 32 is also provided in a cylindrical shape.
