Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and more specifically, to a waterproof patterned light. Background Technology

[0002] Pattern lights are typically installed outdoors to project light spots with specific patterns or brand logos. Generally, pattern lights have a relatively simple structure, mainly consisting of a housing, a lens, and a light source assembly.

[0003] However, some existing pattern lights are not waterproof. When installed outdoors, moisture can easily seep in through the gap between the housing and the lens, forming water inside the housing. This can affect the light source components, pattern disk components, etc. installed inside the housing. In other words, if water accumulates in the housing or cannot be drained, it will cause the light source components or pattern disk components to short-circuit and burn out, making the pattern light unable to operate normally. Summary of the Invention

[0005] A waterproof patterned light includes a patterned sheet for imaging, and further includes: The outer casing includes a cylindrical shell and a radiator, the upper surface of the radiator is sealed against the lower end of the cylindrical shell, and the top of the cylindrical shell is provided with a mounting groove. The light source assembly is mounted on the upper surface of the heat sink; The waterproof lens assembly screws onto the top of the cylindrical housing. By screwing it on, the relative position with the mounting slot is changed, thus achieving a zoom effect. A waterproof partition assembly is used to divide the internal space of a cylindrical shell into two parts, including a near-circular flat plate with a light-transmitting hole in the middle and a flat glass covering the light-transmitting hole. The first space, located above the waterproof partition assembly, is connected to the outside.

[0011] As a further improvement of this utility model, the mounting cylinder is screwed out along the internal thread of the threaded hole, causing the waterproof lens assembly to move upward away from the light source assembly; the mounting cylinder is screwed in along the internal thread of the threaded hole, causing the waterproof lens assembly to move downward toward the light source assembly.

[0012] As a further improvement of this utility model, the number of drainage holes is three, with two drainage holes symmetrically distributed on the upper surface of the cylindrical shell and one drainage hole located on the middle side wall of the cylindrical shell.

[0013] As a further improvement of this utility model, it also includes a pattern disk located between the flat glass and the light source assembly, with pattern pieces mounted on the pattern disk. As a further improvement of this utility model, the waterproof lens assembly, the waterproof partition assembly, the patterned sheet and the light source assembly are coaxial. The light source assembly includes a light source and a condenser lens located above the light source. The diameter of the light-transmitting hole is larger than the diameter of the light-emitting surface of the condenser lens.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) In this utility model, the radiator and the lower end of the cylindrical shell are sealed together.

Detailed Implementation

[0021] Combined with appendix Figure 1 and attached Figure 2 A waterproof patterned light includes a housing 1, a light source assembly 2, a waterproof lens assembly 3, a waterproof partition assembly 4, a patterned piece 5, a first space 13, and a second space 14.

[0022] The outer casing 1 includes a cylindrical shell 11 and a heat sink 12. The upper surface of the heat sink 12 is sealed and abuts against the lower end of the cylindrical shell 11. The top of the cylindrical shell 11 is provided with a mounting groove 111. The cylindrical shell 11 is a shell with openings at both ends. The diameter of the lower end of the cylindrical shell 11 is close to the diameter of the heat sink 12. The heat sink 12 is locked onto the cylindrical shell 11. The upper surface of the heat sink 12 is in close contact with the lower surface of the cylindrical shell 11, thereby sealing the lower end of the cylindrical shell 11. The light source assembly 2 is installed on the upper surface of the heat sink 12. The light source assembly 2 is coaxial with the cylindrical shell 11 and is installed in the middle of the heat sink 12.

[0023] The waterproof lens assembly 3 is screwed onto the top of the cylindrical shell 11. By screwing it on, the relative position with the mounting slot 111 is changed, achieving a zoom effect. The waterproof lens assembly 3 is embedded in the mounting slot 111 and can move up and down along the light emission direction. When the waterproof lens assembly 3 moves upward, it screws out, separating it from the mounting slot 111, and continues to move upward. At this time, the light spot formed by the light emitted through the waterproof lens assembly 3 gradually becomes smaller. When the waterproof lens assembly 3 moves downward, it screws in, bringing it into contact with the mounting slot 111. At this time, the light spot formed by the light emitted through the waterproof lens assembly 3 is the largest. By rotating the waterproof lens assembly 3, it is driven to move up and down, thereby achieving zoom of the waterproof pattern light.

[0024] The waterproof partition assembly 4 is used to divide the internal space of the cylindrical shell 11 into two parts, including a semi-circular flat plate 41 with a light-transmitting hole 411 in the middle and a flat glass 42 covering the light-transmitting hole 411; the waterproof partition assembly 4 is located between the waterproof lens assembly 3 and the light source assembly 2, and is installed on the inner wall of the middle part of the cylindrical shell 11; the patterned sheet 5, the flat glass 42, and the waterproof lens assembly 3 are sequentially located in the light-emitting direction of the light source assembly 2; the light emitted from the light source assembly 2 can pass through the patterned sheet 5, pass through the flat glass 42 located above the patterned sheet, and smoothly enter the waterproof lens assembly 3, and finally be projected onto the outside of the lamp to form a patterned light spot; the first space 13 is located above the waterproof partition assembly 4 and is connected to the outside; the second space 14 is located between the waterproof partition assembly 4 and the heat sink 12 and is a sealed space.

[0025] Because the diameter of the mounting slot 111 is slightly larger than the diameter of the waterproof lens assembly 3, a gap exists between the waterproof lens assembly 3 and the cylindrical shell 11 when the waterproof lens assembly 3 is zooming. Therefore, external moisture can enter the internal space of the cylindrical shell 11 through the gap between the waterproof lens assembly 3 and the cylindrical shell 11. Traditional pattern lights do not have a waterproof partition assembly between the waterproof lens assembly and the light source assembly. After external moisture enters the shell, it will affect the light source assembly, causing the light source assembly to short-circuit and burn out. In this embodiment, a waterproof partition assembly 4 is added between the waterproof lens assembly 3 and the light source assembly 2. The waterproof partition assembly 4 divides the internal space of the shell 1. The system comprises an upper first space 13 and a lower second space 14. A waterproof lens assembly 3 is embedded in the upper part of the first space 13, while a patterned sheet 5 and a light source assembly 2 are installed inside the second space 14. The first space 13 and the second space 14 are independent of each other. The second space 14 is a sealed waterproof cavity formed by a cylindrical shell 11, a waterproof partition assembly 4, and a heat sink 12. Therefore, even if external moisture enters the first space 13, it cannot affect the normal operation of the patterned sheet 5 or the light source assembly 2; that is, moisture entering the first space 13 cannot enter the second space 14. The second space 14 can protect the patterned sheet 5 and the light source assembly 2 from external moisture. The beneficial effect of this embodiment is that by adding a waterproof partition assembly 4 between the waterproof lens assembly 3 and the light source assembly 2, the internal space of the cylindrical shell 11 is divided into two parts, with the second space 14 being a sealed space that can protect the light source assembly 2 installed in the second space 14 from external moisture interference.

[0026] As a new implementation method, combined with the appendix Figure 2 Appendix Figure 4 and attached Figure 5The waterproof partition assembly 4 also includes a first waterproof rubber ring 43 and a second waterproof rubber ring 44. The intersection of the waterproof partition assembly 4 and the inner wall of the cylindrical shell 11 is provided with a first mounting groove 112, and the intersection of the upper surface of the radiator 12 and the lower end of the cylindrical shell 11 is provided with a second mounting groove 113. The first waterproof rubber ring 43 is adapted to the first mounting groove 112, and the second waterproof rubber ring 44 is adapted to the second mounting groove 113. Mounting groove 112 is located on the inner wall of the middle part of the cylindrical shell 11, and mounting groove 213 is located on the lower surface of the cylindrical shell 11. The thickness of the first waterproof rubber ring 43 is greater than the depth of the mounting groove 112, and the thickness of the second waterproof rubber ring 44 is greater than the depth of the mounting groove 213. When the first waterproof rubber ring 43 is installed in mounting groove 112, the upper surface of the near-circular flat plate 41 is in close contact with the first waterproof rubber ring 43, which can divide the internal space of the cylindrical shell 11 into two independent spaces. Similarly, when the second waterproof rubber ring 44 is installed in mounting groove 213, the upper surface of the radiator 12 is in close contact with the second waterproof rubber ring 44, which seals the lower end of the cylindrical shell 11 and prevents external moisture from entering the second space 14 from the gap between the cylindrical shell 11 and the radiator 12. The beneficial effect of this embodiment is that it helps to prevent external moisture from entering the second space 14 from the intersection of the waterproof partition assembly 4 and the cylindrical shell 11 or the intersection of the radiator 12 and the cylindrical shell 11, thus affecting the normal operation of the light source assembly 2.

[0027] As a new implementation method, combined with the appendix Figure 1 Appendix Figure 4 and attached Figure 5 The upper part of the cylindrical shell 11 is provided with several drainage holes 114, through which water entering the first space 13 from the outside is discharged. In this embodiment, the drainage holes 114 are circular through holes; the drainage holes 114 are all distributed above the waterproof partition assembly 4, which can ensure that the second space 14 is a sealed space; after external water vapor enters the first space 13 through the gap between the waterproof lens assembly 3 and the cylindrical shell 11, the drainage holes 114 on the upper part of the cylindrical shell 11 can discharge the water vapor from the first space 13; preventing water vapor from accumulating inside the first space 13 and forming water mist on the light-emitting surface of the flat glass 42, thus affecting the light emission effect of the lamp; after external water vapor enters the first space 13 through the gap between the waterproof lens assembly 3 and the cylindrical shell 11, the waterproof pattern lamp can be shaken up and down or left and right, so that the water inside the lamp can be discharged from the first space 13 through the drainage holes 114. The beneficial effect of this embodiment is that it can drain the water inside the first space 13 in a timely manner, prevent the humidity inside the first space 13 from being too high and forming water mist on the light-emitting surface of the flat glass 42; and prevent the internal parts installed in the first space 13 from being in a humid environment for a long time and rusting and corroding.

[0028] As a new implementation method, combined with the appendix Figure 2 Appendix Figure 4 and attached Figure 5The waterproof lens assembly 3 includes a stepped mounting tube 31 and a lens 32 located inside the mounting tube. The outer surface of the mounting tube 31 is threaded. The mounting cylinder 31 includes a clamping cover at the top for clamping the lens and a cylinder body for mounting the lens. The diameter of the clamping cover is larger than the diameter of the cylinder body. When the waterproof lens assembly 3 abuts against the mounting groove 111, the lower end of the clamping cover is in close contact with the bottom surface of the mounting groove 111. At this time, the waterproof lens assembly 3 is in close contact with the cylindrical shell 11, making it difficult for external water vapor to enter the interior of the cylindrical shell 11. The diameter of the lens 32 is slightly smaller than the diameter of the cylinder body of the mounting cylinder 31. The lens 32 can be installed inside the mounting cylinder 31 to form a sealed waterproof lens assembly 3, preventing external water vapor from entering the waterproof lens assembly 3. This effectively prevents water vapor from condensing on the light-incident or light-exiting surface of the lens 32, thus affecting the light output effect of the waterproof pattern light. When the waterproof lens assembly 3 moves upward, there is a gap between the mounting cylinder 31 and the cylindrical shell 11, allowing external water vapor to enter the interior of the cylindrical shell 11 through the gap. The mounting cylinder 31 is threadedly connected to the cylindrical shell 11, meaning that the pattern light can be zoomed by rotating the waterproof lens assembly 3 clockwise or counterclockwise. The beneficial effect of this embodiment is that the mounting cylinder 31 is threadedly connected to the cylindrical shell 11, and the relative position of the mounting cylinder 31 and the cylindrical shell 11 can be adjusted according to the needs to achieve different sizes of light spots.

[0029] As a new implementation method, combined with the appendix Figure 2 Appendix Figure 4 and attached Figure 5 The outer casing 1 also includes a swivel plate 15 locked to the bottom of the mounting slot 111. The swivel plate 15 has a threaded hole in the middle that matches the mounting cylinder 31, and the mounting cylinder 31 is threadedly connected to the swivel plate 15. The swivel plate 15 is a near-circular flat plate, and the periphery of the threaded hole has multiple mounting holes for mounting the swivel plate 15. The bottom of the mounting slot 111 has multiple mounting posts that correspond one-to-one with the mounting holes, and the swivel plate 15 is locked to the mounting posts at the bottom of the mounting slot 111. The waterproof lens assembly 3 passes through the mounting slot 111 and is threadedly connected to the swivel plate 15 at the bottom of the mounting slot 111. The waterproof lens assembly 3 can change its relative position with the mounting slot 111 by rotating clockwise or counterclockwise to achieve the zoom effect of the pattern light. The beneficial effect of this embodiment is that, compared with lamps with knobs mounted on the side wall, the waterproof lens assembly 3 is threadedly connected to the screw plate 15, which can reduce the gap between the waterproof lens assembly 3 and the cylindrical shell 11, reducing the channels for external moisture to enter the interior of the cylindrical shell 11; and zooming can be achieved by rotating the waterproof lens assembly 3 with one hand, simplifying the zooming process.

[0030] As a new implementation method, combined with the appendix Figure 3 Appendix Figure 4 and attached Figure 5The circular plate 41 also includes a mounting groove 412 adjacent to the light-transmitting hole 411 and mounting holes 413 evenly distributed along the outer periphery. The flat glass 42 is covered in the mounting groove 412 above the light-transmitting hole. The diameter of mounting groove 3 412 is slightly larger than the diameter of light-transmitting hole 411, and the groove depth of mounting groove 3 412 is less than the thickness of the near-circular plate 41. Mounting groove 3 412 is located on the upper surface of near-circular plate 41, and the thickness of flat glass 42 is greater than the groove depth of mounting groove 3 412. Therefore, flat glass 42 is fixed in mounting groove 3 412 by dispensing or other means, and the light-emitting surface of flat glass 42 is higher than the upper surface of near-circular plate 41. If the light-emitting surface of flat glass 42 is lower than the upper surface of near-circular plate 41, water entering the first space 13 will vaporize and accumulate on the light-emitting surface of flat glass 42, affecting the emitted light through flat glass 42 and thus affecting the light emission effect of the pattern light. Conversely, when the light-emitting surface of flat glass 42 is higher than the upper surface of near-circular plate 41, the water will flow away along the upper surface of near-circular plate 41 and will not easily accumulate on the light-emitting surface of flat glass 42. The beneficial effect of this embodiment is that the flat glass 42 is covered by the mounting groove 3 412, so that the light-emitting surface of the flat glass 42 is higher than the upper surface of the near-circular flat plate 41, which can effectively prevent water from overflowing onto the light-emitting surface of the flat glass 42 and avoid the water vapor inside the first space 13 from affecting the light emission effect of the waterproof pattern light.

[0031] As a new implementation method, combined with the appendix Figure 4 and attached Figure 5The mounting cylinder 31 is screwed out along the internal thread of the threaded hole, causing the waterproof lens assembly 3 to move upward away from the light source assembly 2; the mounting cylinder 31 is screwed in along the internal thread of the threaded hole, causing the waterproof lens assembly 3 to move downward toward the light source assembly 2. In this embodiment, the adjustment of the waterproof lens assembly 3 is manual; when the waterproof lens assembly 3 is in zoom state one, the waterproof lens assembly 3 is manually rotated clockwise, and the mounting cylinder 31 is screwed in along the threaded hole, so that the waterproof lens assembly 3 gradually approaches the light source assembly until it abuts against the mounting through groove 111. At this time, the light spot formed by the emitted light from the light source assembly 2 is the largest; when the waterproof lens assembly 3 is in zoom state two, the waterproof lens assembly 3 is manually rotated counterclockwise, and the mounting cylinder 31 is screwed out along the threaded hole, and the waterproof lens assembly 3 moves upward. The farther the waterproof lens assembly 3 is from the light source assembly, the smaller the light spot formed by the emitted light from the light source assembly 2; traditional manual focusing Pattern lights typically use focusing knobs on both sides of the housing for focusing. This often results in inconsistent focusing distances on both sides, causing the center of the waterproof lens assembly to deviate from the light emission direction of the light source assembly, affecting the light output of the pattern light. Compared to traditional manually focused pattern lights, this embodiment achieves zoom by controlling the waterproof lens assembly 3 to screw in or out of the rotating plate 15. In practical applications, the rotation angle of the waterproof lens assembly 3 can be adjusted according to different needs, effectively avoiding the drawbacks of traditional manually focused lights, such as the waterproof lens immediately sliding down after releasing the knob, or the center of the waterproof lens assembly 3 deviating from the light emission direction of the light source assembly 2. The beneficial effect of this embodiment is that the mounting cylinder 31 screws in or out along the internal thread of the threaded hole, which allows for precise control of the rotation angle of the waterproof lens assembly 3, facilitating precise adjustment of the light spot size. Furthermore, during adjustment, the center of the waterproof lens assembly 3 remains located in the light emission direction of the light source assembly 2 without any deviation.

[0032] As a new implementation method, combined with the appendix Figure 1 Appendix Figure 4 and attached Figure 5There are three drainage holes 114, with two symmetrically distributed on the upper surface of the cylindrical shell 11 and one located on the middle side wall of the cylindrical shell 11. Since the pattern light is typically installed outdoors, external moisture can easily enter the first space 13 through the gap between the waterproof lens assembly 3 and the cylindrical shell 11. The drainage holes 114 on the cylindrical shell 11 facilitate faster drainage of moisture from the first space 13. When the light-emitting end of the pattern light faces the ground, the moisture in the first space 13 is mainly discharged through the two symmetrically distributed drainage holes 114 on the upper surface of the cylindrical shell 11. When the light-emitting end of the pattern light faces away from the ground, the moisture in the first space 13 is mainly discharged through the drainage holes 114 on the side wall of the cylindrical shell 11. The beneficial effect of this embodiment is that by providing drainage holes 114 on the middle side wall and upper surface of the cylindrical shell 11, moisture in the first space 13 can be discharged regardless of how the pattern light is installed, which is beneficial for the rapid drainage of moisture from the first space 13.

[0033] As a new implementation method, combined with the appendix Figure 2 and attached Figure 4 It also includes a pattern disk located between the flat glass 42 and the light source assembly 2, with a pattern piece 5 mounted on the pattern disk. The pattern disk includes a rotating pattern base and a fixing plate for rotating the pattern base. The rotating pattern base is driven to rotate by a drive device, and the pattern piece 5 is mounted in the middle of the rotating pattern base. When the rotating pattern base rotates, the pattern piece 5 mounted in the middle of the rotating pattern base also rotates. The pattern disk is installed in a waterproof second space 14, which can prevent external moisture from affecting the drive device and causing the pattern disk to fail to rotate. The beneficial effect of this embodiment is that the pattern disk is installed in the second space 14, which prevents external moisture from affecting the normal operation of the pattern disk and can extend the service life of the waterproof pattern light.

[0034] As a new implementation method, combined with the appendix Figure 4 and attached Figure 5The waterproof lens assembly 3, waterproof partition assembly 4, pattern sheet 5, and light source assembly 2 are coaxial. The light source assembly 2 includes a light source 21 and a condenser lens 22 located above the light source 21. The diameter of the light-passing aperture 411 is larger than the diameter of the light-emitting surface of the condenser lens 22. The light-incident surface of the condenser lens 22 is much larger than the light-emitting surface of the light source 21, allowing all the light emitted from the light source 21 to enter the condenser lens 22. The condenser lens 22 is used to converge the light emitted from the light source 21, so that most of the emitted light can pass through the pattern sheet 5. When the diameter of the light-passing aperture 411 is larger than the diameter of the light-emitting surface of the condenser lens 22, most of the emitted light passing through the pattern sheet 5 located in the second space 14 can pass through the flat glass 42 in the middle of the waterproof partition assembly 4, and then continue to pass through the lens 32 in the middle of the waterproof lens assembly 3 located in the first space 13, projecting onto the outside of the pattern lamp to form a light spot with a special pattern. The beneficial effect of this embodiment is that the diameter of the light-transmitting aperture 411 is larger than the diameter of the light-emitting surface of the condenser lens 22. Most of the emitted light rays passing through the condenser lens 22 can pass through the flat glass 42 on the light-transmitting aperture 411 and exit from the lens 32 in the waterproof lens assembly 3, which is beneficial to improving the luminous flux of the pattern light.

[0035] The working principle of the technical solution of this utility model is explained as follows, as shown in the appendix. Figure 1 To be continued Figure 5 As shown, the waterproof partition assembly 4 divides the internal space of the cylindrical shell 11 into upper and lower parts; the upper space is a first space 13 that communicates with the outside, and the lower space is a sealed and waterproof second space 14; the light source assembly 2 is installed in the waterproof second space 14, and the waterproof lens assembly 3 is installed on the first space 13 that communicates with the outside; when the waterproof lens assembly 3 is screwed into or out of the screw plate 15 to achieve zoom, external water vapor can enter the first space 13 through the gap between the waterproof lens assembly 3 and the cylindrical shell 11. Therefore, a drainage hole 114 is provided on the upper part of the cylindrical shell 11, and the water vapor in the first space 13 can be discharged through the drainage hole 114 to prevent water from accumulating inside the first space 13.
