[0034] refer to Figures 1 to 4 The lamp 101 according to an embodiment of the present invention includes a housing assembly 102, a lens 103 and a light source 401. The lens 103 is connected to the housing assembly 102 and together defines a space in front of the mirror 404, a space behind the mirror 403 and a light source space 402. The light source 401 is installed in the light source space 402, and the light emitted by the light source 401 can pass through the light source space 402, the space behind the mirror 403, the lens 103 and the space in front of the mirror 404 in sequence. The housing assembly 102 is formed with a first drainage channel and a second drainage channel, the first drainage channel is connected to the space in front of the mirror 404, and the first drainage channel is used to drain water from the space in front of the mirror 404, the second drainage channel is connected to the space behind the mirror 403, and the second drainage channel is used to drain water from the space behind the mirror 403. Water seeps into the shell component 102 mainly to cover the lens 103 or block the direction of the light source 401, affecting the lighting effect. The space before and after the lens 103 needs to adjust the position of the lens 103 to change the beam angle, or needs to replace a different lens 103, and there are gaps between the components, so it is easy for water to seep in. The lamp 101 of the embodiment of the present invention is provided with a first drainage channel and a second drainage channel in the shell component 102, and the outlets of the two drainage channels are respectively located outside the space in front of the mirror 404 and the space behind the mirror 403. Both the space in front of the mirror 404 and the space behind the mirror 403 are drained to reduce the impact of accumulated water on the lens 103, thereby improving the lighting effect.

[0035] It should be noted that in some embodiments of the present invention, there are certain gaps between the rear end face of the first shell 104 and the front end face of the second shell 201, between the outer circumference of the second shell 201 and the inner circumference of the adjustment ring 106, between the inner circumference of the second shell 201 and the outer circumference of the rear shell 105, etc., because there is a need to adjust the position of the lens 103, and the drainage paths of the first drainage channel and the second drainage channel are also mainly drained by cooperating with the structures mentioned below and the gaps at the above positions, that is, after the water in the space in front of the mirror 404 and the space behind the mirror 403 enters the above gap, it will be discharged along the gap, thereby achieving the purpose of drainage.

[0036] refer to Figures 1 to 4 as well as Figure 8 and Fig. 9 In some embodiments of the present invention, the housing assembly 102 includes a rear shell 105 and a drain ring 202. The rear shell 105 includes a first body portion 405 and a partition plate 406, wherein the partition plate 406 is disposed in the first body portion 405, and the first body portion 405 surrounds the outer periphery of the partition plate 406, and the partition plate 406 includes a first surface 407 and a second surface 408 disposed opposite to each other, wherein the first surface 407 serves as a part of the inner wall surface of the light source space 402, and the second surface 408 serves as a part of the inner wall surface of the mirror rear space 403. The drain ring 202 is installed in the first body part 405 and connected to the second surface 408. The inner circumference of the drain ring 202 is provided with a first through hole 901, the outer circumference of the drain ring 202 is provided with a second through hole 902, the first body part 405 is provided with a third through hole 801, the third through hole 801 and the drain ring 202 are located on the same side of the partition plate 406, the outer circumference of the drain ring 202 abuts against the inner circumference of the first body part 405, the drain ring 202 and the second surface 408 jointly define a drain groove 905, the first through hole 901, the drain groove 905, the second through hole 902 and the third through hole 801 are sequentially connected, and the first through hole 901 and the second through hole 902 are staggered in the circumferential direction of the drain ring 202. Among them, the second drainage channel includes the first through hole 901, the drain groove 905, the second through hole 902 and the third through hole 801.

[0037] If a hole is directly opened on the first main body 405 to drain the space behind the mirror 403, part of the light may be emitted directly from the hole, causing light leakage. The drainage ring 202 of the embodiment of the present invention is provided with a first through hole 901 and a second through hole 902 that are staggered from each other. Since the first through hole 901 and the second through hole 902 are staggered from each other, it can meet the drainage requirements of the space behind the mirror 403 while preventing the light entering the space behind the mirror 403 from the light source space 402 from being emitted directly along the drainage path, thereby avoiding light leakage. In addition, there is no need to make major changes to the rear shell 105 or the second shell 201. The separately provided drainage ring 202 is more convenient to improve and install. The drainage path of the second drainage flow channel here is as follows: the water in the space behind the mirror 403 enters the drainage groove 905 from the first through hole 901 on the inner circumference of the drainage ring 202, flows along the drainage groove 905 to the second through hole 902, and then flows from the second through hole 902 to the third through hole 801 and then is discharged. It should be noted that, in some embodiments of the present invention, the first shell 104 and the second shell 201 clamp the lens 103 and can move along the axial direction of the lens 103, so the rear space 403 will also change accordingly, but it does not affect the drainage of the rear space 403. When the third through hole 801 is not exposed to the outside, refer to Figure 4 , Figure 8 as well as Fig. 9After the water flows out of the second through hole 902, it is located between the outer circumference of the rear shell 105 and the inner circumference of the second shell 201. There is a gap there, so the water can still be drained.

[0038] refer to Fig. 9 In some embodiments of the present invention, a plurality of drainage grooves 905 are provided. For a first through hole 901 and a second through hole 902 connected to the same drainage groove 905, the line connecting the first through hole 901 and the center of the drainage ring 202 is the first axis 903, the line connecting the second through hole 902 and the center of the drainage ring 202 is the second axis 904, and the angle between the first axis 903 and the second axis 904 is greater than 20°. Such a design can increase the curvature between the first through hole 901 and the second through hole 902, increase the number of reflections of the light in the drainage groove 905, and reduce the probability that the light enters from the first through hole 901 and is emitted from the second through hole 902 after multiple reflections, thereby reducing the corresponding light transmission problem.

[0039] refer to Figure 1 , Figure 4 as well as Figure 8 In some embodiments of the present invention, at least two third through holes 801 are disposed at the bottom end of the rear housing 105. Figure 3 and Figure 8 , there are various components such as a controller and an electrical connector on the back of the lamp 101, so there is a distinction between the upper and lower parts. In the actual use scenario of the lamp 101, the lamp 101 is usually Figure 4 , Figure 8 The state shown in FIG. 1 is that if there is water accumulation, it will basically accumulate at the bottom. Therefore, at least two third through holes 801 are provided at the bottom of the rear shell 105 to accelerate the drainage for commonly used scenarios, and as shown in FIG. Figure 8 The arrangement shown can also reduce the water level.

[0040] It should be noted that, in some embodiments of the present invention, multiple third through holes 801 can be provided, and they can be distributed asymmetrically or symmetrically arranged on the periphery of the rear shell 105. For example, four are designed to be symmetrical in the center, and four second through holes 902 are correspondingly arranged on the drainage ring 202. In this way, when the lamp 101 is rotated to various angles, there is at least one third through hole 801 facing downward to meet the drainage of the space 403 behind the mirror.

[0041] refer to Figures 1 to 5In some embodiments of the present invention, the lens 103 includes a light-incoming surface 409 and a light-outgoing surface 410 facing each other, the light-incoming surface 409 faces the light source 401, and the housing assembly 102 includes a first housing 104, a second housing 201, and a rear housing 105. The first housing 104 is annular, and the second housing 201 is annular. In the axial direction of the lens 103, the first housing 104 and the second housing 201 are connected and jointly clamp the edge of the lens 103. The rear housing 105 includes a first body 405 and a partition plate 406, the partition plate 406 is arranged in the first body 405, the first body 405 surrounds the outer periphery of the partition plate 406, and the partition plate 406 includes a first surface 407 and a second surface 408 arranged in opposite directions. The second housing 201 can be movably sleeved on the outer periphery of the rear housing 105, and the first housing 104 and the second housing 201 can move relative to the rear housing 105 to change the distance between the lens 103 and the light source 401. The inner circumference of the first shell 104 and the light emitting surface 410 jointly define the space 404 in front of the mirror, the second shell 201, the light inlet surface 409, the first body 405 and the second surface 408 jointly define the space 403 behind the mirror, and the first body 405 and the first surface 407 jointly define the light source space 402. By adjusting the positions of the first shell 104 and the second shell 201, the position of the lens 103 clamped therebetween can be changed, thereby changing the distance between the lens 103 and the light source 401 of the lamp 101, thereby changing the beam angle, which affects the lighting effect. Different beam angles are suitable for different scenes. Therefore, the above design can make the lamp 101 suitable for more scenes and improve adaptability.

[0042] refer to Figures 3 to 7In some embodiments of the present invention, the second shell 201 includes an inner ring portion 411 and an inner peripheral portion 412, the inner peripheral portion 412 surrounds the periphery of the inner ring portion 411, the inner ring portion 411 abuts against the light-incoming surface 409, and the inner peripheral portion 412 surrounds the periphery of the lens 103. The first shell 104 includes a second body portion 501 and a plurality of protrusions 502, the protrusions 502 protrude from the end surface of the second body portion 501 toward one end of the lens 103, the plurality of protrusions 502 are arranged at intervals along the circumference of the second body portion 501, the protrusions 502 abut against the light-emitting surface 410, the protrusions 502, the end surface of the second body portion 501 and the lens 103 jointly define a first gap 503, a second gap 504 is formed between the inner peripheral portion 412 and the outer peripheral surface of the second body portion 501, the first gap 503 is connected to the second gap 504, and the first drainage channel includes the first gap 503 and the second gap 504. A plurality of spaced-apart protrusions 502 are provided on the second main body portion 501, so that the first shell 104 does not completely abut against the light-emitting surface 410 of the lens 103, thereby forming a first gap 503. Because there is a second gap 504 between the inner circumference 412 and the outer circumference of the second main body portion 501, water in the space 404 in front of the lens can be discharged along the first gap 503, the second gap 504 and then from the gap between the first shell and the front end face, or the gap between the second shell and the adjustment ring 106.

[0043] It should be noted that the reference Figure 1 The space 404 in front of the mirror is an open space and can be poured out directly in most cases. However, if the lamp 101 is used upward, the water in the space 404 in front of the mirror may accumulate on the light-emitting surface 410 of the lens 103 and affect the lighting effect. Therefore, a protrusion 502 is provided on the second main body 501 so that the water on the light-emitting surface 410 can be discharged along the first gap 503. The improvement in this area does not require too high a cost, but can effectively solve the problem of water accumulation.

[0044] refer to Figure 4 , Figure 5 , Figure 7 and Fig.10In some embodiments of the present invention, at least one of the inner ring portion 411 and the inner peripheral portion 412 is provided with a first through groove 505, and the first through groove 505 connects the space in front of the mirror 404 and the space behind the mirror 403. After the first through groove 505 connects the space in front of the mirror 404 and the space behind the mirror 403, the accumulated water in the two spaces can be interconnected, so that the first drainage channel and the second drainage channel can be used together to achieve drainage. For example, when the lamp 101 is used downward, the accumulated water in the space behind the mirror 403 can flow into the space in front of the mirror 404 through the first through groove 505, and then be directly discharged from the opening of the space in front of the mirror 404 under the action of gravity. When the lamp 101 is used upward, the opening of the space in front of the mirror 404 cannot be drained smoothly, and the accumulated water in the space in front of the mirror 404 flows into the space behind the mirror 403 through the first through groove 505 under the action of gravity, so as to use the second drainage channel such as the drainage ring 202 of the space behind the mirror 403 to drain water, and the interconnection between the two can improve the drainage efficiency.

[0045] It should be noted that the reference Figure 5 and Figure 7 In some embodiments of the present invention, the first through groove 505 is provided at the outer edge of the inner ring portion 411. In this case, the diameter of the lens 103 needs to be set smaller than the inner diameter of the inner circumference portion 412, so as to form an annular concave pit, which is connected to the first through groove 505, so as to achieve the communication between the space in front of the lens 404 and the space behind the lens 403. In some embodiments of the present invention, the first through groove 505 can also be provided on the inner circumference portion 412. The first through groove 505 is provided along the axial direction of the lens 103 and passes through the space in front of the lens 404 and the space behind the lens 403. In this case, there is no need to limit the diameter of the lens 103, and the two spaces can also be connected.

[0046] It should be noted that the reference Figure 5 In some embodiments of the present invention, the outer edge of the lens 103 is made thinner than the central area and forms a slope, so that water on the light-emitting surface 410 can more easily flow to the first gap 503 at the outer edge of the lens 103, thereby achieving better drainage.

[0047] refer to Figure 4 , Figure 7 and Fig.10In some embodiments of the present invention, the second shell 201 has a front end portion 413, which is arranged along the radial direction of the lens 103. The front end portion 413 and the inner ring portion 411 are respectively connected to the two ends of the inner circumference 412. The front end portion 413 is provided with a second through groove 701, which is connected to the space behind the mirror 403. The second drainage channel includes the second through groove 701. In this way, when the lamp 101 is tilted downward for use, water in the space behind the mirror 403 will flow to the front end portion 413, and then flow out of the second through groove 701, and then flow out through the gap between the front end portion 413 and the first shell 104, and the gap between the outer peripheral surface of the second shell 201 and the adjustment ring 106, thereby realizing the drainage process. After the front end portion 413 is grooved, it is blocked by the first shell 104 when in use, and it will not affect the use and lighting effects.

[0048] refer to Figures 2 to 4 , Figure 7 and Fig.10 In some embodiments of the present invention, the housing assembly 102 further includes an adjustment ring 106. The adjustment ring 106 is rotatably mounted on the outside of the second housing 201. The adjustment ring 106 can rotate relative to the second housing 201 around the central axis of the lens 103 so that the second housing 201 moves along the axial direction of the lens 103. The adjustment ring 106 can be arranged to better adjust the movement of the second housing 201. It is sufficient to rotate the adjustment ring 106 to change the distance between the lens 103 and the light source 401, thereby changing the size of the beam angle. Further, referring to Figure 2 and Figure 3 In some embodiments of the present invention, anti-slip patterns may be provided on the outer circumference of the adjusting ring 106 so that the adjusting ring 106 can rotate better.

[0049] refer to Figure 2 , Figure 4 , Figure 7 as well as Fig.10 In some embodiments of the present invention, a third through groove 702 is provided on the outer circumference of the second shell 201, the third through groove 702 is connected to the rear-mirror space 403, and the second drainage channel includes the third through groove 702. When the lamp 101 is used near a horizontal position, the accumulated water is not stored at the front and rear ends but on the inner circumference of the rear-mirror space 403, that is, the position of the corresponding outer circumference of the second shell 201. Therefore, the third through groove 702 is provided here, so that the accumulated water can flow out of the rear-mirror space 403 along the third through groove 702, and flow to the gap between the outer circumference of the second shell 201 and the inner circumference of the adjustment ring 106, and then be discharged along the gap to achieve drainage. Therefore, the design of the third through groove 702 can enable the lamp 101 to meet the drainage requirements of more angles of use scenarios.

[0050] refer to Figures 2 to 4 , Figure 7 and Fig.10 In some embodiments of the present invention, a third through groove 702 is provided on the outer circumferential surface of the second shell 201, and the third through groove 702 is straight and extends along the axial direction of the lens 103. The adjustment ring 106 is provided with a slide groove 414, and the two ends of the slide groove 414 are distributed along the radial direction of the lens 103 and the circumferential direction of the lens 103. The rear shell 105 is provided with a slider 415, and the slider 415 is slidably disposed in the third through groove 702 and the slide groove 414. When the adjustment ring 106 rotates relative to the second shell 201, the slider 415 slides in the third through groove 702 and the slide groove 414, and the adjustment ring 106 moves synchronously with the second shell 201 to change the distance between the lens 103 and the light source 401. In this design, since the slider 415 passes through the third through groove 702 and the slide groove 414, when the adjusting ring 106 rotates, the slider 415 slides in the slide groove 414, and the adjusting ring 106 can rotate and move along the axial direction of the lens 103, and the third through groove 702 of the second shell extends straight along the axial direction of the lens 103, limiting the circumferential rotation of the second shell along the lens 103, so that the second shell can only move along the axial direction of the lens 103, thereby limiting the rotation of the first shell, the second shell and the lens 103 itself, reducing the risk of collision with surrounding objects during rotation, thereby causing the lens hood or other accessories to fall off or be damaged.

[0051] It should be noted that, in some embodiments of the present invention, the third through groove 702 and the third through hole 801 are provided in plurality and distributed along the circumference of the lens 103, and are both used to drain water. Therefore, the above structures can be arranged at the same position in the circumference of the lens 103, for example, both are arranged at the bottom end of the lamp 101, and four are symmetrically designed along the circumference, etc., and the arrangement in a unified manner can make the lamp 101 Figure 4 When used in the scenario shown, the third through groove 702 and the third through hole 801 are both located at the bottom of the lamp 101, and can simultaneously drain the space 403 behind the mirror, thereby improving the drainage efficiency.

[0052] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
