Detailed Implementation

[0020] Combined with appendix Figure 1 To be continued Figure 4A waterproof lighting fixture includes a housing 1, a waterproof lens assembly 3 fitted onto the top of the housing 1, a waterproof cover 4 disposed inside the housing 1, and a light source assembly 2. The inner wall of the top of the housing 1 has a mounting groove 11. The light source assembly 2 is disposed inside the housing and coaxial with the mounting groove 11. The waterproof lens assembly 3 is fitted into the mounting groove 11, and the waterproof lens assembly 3 slides within the mounting groove 11. The waterproof cover 4 and the waterproof lens assembly 3 are sequentially located in the light-emitting direction of the light source assembly 2. The mounting groove 11 is a cylindrical groove, and the waterproof lens assembly 3 is a stepped cylindrical structure, adapted to the mounting groove 11. The light emitted by the light source assembly 2 can pass through the waterproof lens assembly 3 located within the mounting groove 11 and be projected onto the outside of the lighting fixture. The waterproof lens assembly 3... The light emission direction of the light source assembly 2 slides up and down within the mounting groove 11. The height of the waterproof lens assembly 3 is greater than the depth of the mounting groove 11. The waterproof lens assembly 3 has two states: an adjustment state and a locking state. When the waterproof lens assembly 3 is in the locking state, it is locked and fixed to the outer shell 1. When the waterproof lens assembly 3 is in the adjustment state, it can move up and down relative to the outer shell 1. At this time, the waterproof cover 4 is connected to the lower end of the waterproof lens assembly 3. The waterproof cover 4 is used to support the waterproof lens assembly 3 and prevent it from sliding down rapidly when it enters the adjustment state, thus affecting the adjustment of the waterproof lens assembly 3. The light emission surface of the waterproof lens assembly 3 can be higher or lower than the upper surface of the mounting groove 11. The outer casing 1 is provided with a mounting groove 11, and the interior of the outer casing 1 is connected to the outside through the mounting groove 11. Moisture entering the interior of the outer casing 1 can easily cause a short circuit in the light source assembly 2, making the light source assembly 2 unable to work properly. Therefore, in this embodiment, a waterproof cover 4 is provided between the waterproof lens assembly 3 and the outer casing 1. The waterproof cover 4 is a trapezoidal corrugated tubular structure extending from the upper end to the lower end. The waterproof cover 4 is located between the waterproof lens assembly 3 and the middle inner wall of the outer casing 1. The lower end of the waterproof cover 4 is locked to the middle inner wall of the outer casing 1, and the upper end of the waterproof cover 4 is linked and attached to the lower end of the waterproof lens assembly 3. That is, when the waterproof lens assembly 3 moves along the light emission direction, the upper end of the waterproof cover 4 also moves with the movement of the waterproof lens assembly 3. The waterproof lens assembly 3, the waterproof cover 4, and the outer casing 1 together form a sealed waterproof cavity 5, and the outer casing 1 covers the outside of the waterproof cavity 5.

[0021] The diameter of the upper end of the waterproof cover 4 is approximately the same as the diameter of the lower end of the waterproof lens assembly 3. The upper end of the waterproof cover 4 can fit tightly against the lower end of the waterproof lens assembly 3, preventing external moisture from entering the waterproof cavity 5. The outer shell 1 has an elliptical shell structure, and the diameter of the lower end of the waterproof cover 4 is approximately the same as the diameter of the inner wall in the middle of the outer shell 1. The lower end of the waterproof cover 4 can fit tightly against the inner wall in the middle of the outer shell 1, effectively preventing moisture entering the outer shell 1 from entering the waterproof cavity 5. The beneficial effect of this embodiment is that by setting a waterproof cover 4 between the outer shell 1 and the waterproof lens assembly 3, the waterproof cover 4 forms a waterproof cavity 5 between the waterproof lens assembly 3 and the outer shell 1. External moisture can be effectively blocked by the waterproof cover 4, and even if the lamp is used outdoors for a long time, the light source component 2 inside the lamp will not short-circuit due to water ingress caused by the outdoor humid environment or rainy weather.

[0022] As a novel implementation, referring to the accompanying drawings, the waterproof lens assembly 3 moves in a direction away from or towards the light source assembly 2. The waterproof cover 4 has an elastic corrugated structure, and its upper end is linked to the lower end of the waterproof lens assembly 3. Therefore, when the waterproof lens assembly 3 moves away from the light source assembly 2, the waterproof cover 4 stretches in the direction away from the light source assembly 2, and the waterproof cavity 5 also increases as the waterproof cover 4 stretches. When the waterproof lens assembly 3 moves towards the light source assembly 2, the waterproof cover 4 compresses in the direction towards the light source assembly 2, and the waterproof cavity 5 also decreases as the waterproof cover 4 compresses. During this process, the upper end of the waterproof cover 4 is always in close contact with the lower end of the waterproof lens assembly 3, and the lower end of the waterproof cover 4 is always in close contact with the inner wall of the middle part of the outer shell 1, ensuring that the waterproof cavity 5 is always in a sealed state. The beneficial effect of this embodiment is that the waterproof lens assembly 3 can adjust the focal length in the light output direction to change the light output effect of the lamp. At the same time, the waterproof performance of the lamp will not be affected when the waterproof lens assembly 3 moves, and it can effectively prevent water vapor from entering the waterproof cavity 5.

[0023] As a new implementation method, combined with the appendix Figure 3The waterproof cover 4 has annular attachment edges 41 at its upper and lower ends, and multiple mounting holes 411 for fixing are provided on the attachment edges 41. The attachment edges 41 are annular flat plates, and the outer periphery of the attachment edges 41 is connected to the side wall of the waterproof cover 4. The thickness of the attachment edges 41 is slightly greater than the thickness of the side wall of the waterproof cover 4, which is more conducive to the installation of the waterproof cover 4. The attachment edges 41 are fixed to the lower end of the waterproof lens assembly 3 by fasteners passing through the mounting holes 411. If the thickness of the attachment edges 41 is too thin, the attachment edges 41 are prone to deformation, which will cause the attachment edges 41 to fail to fully fit the lower surface of the waterproof lens assembly 3 when the waterproof cover 4 moves with the waterproof lens assembly 3. Water vapor can easily enter the waterproof cavity 5 through the gap between the attachment edges 41 and the waterproof lens assembly 3. The beneficial effect of this embodiment is that the attachment edge 41 at the upper end of the waterproof cover 4 can fit tightly with the lower end of the waterproof lens assembly 3, and the attachment edge 41 at the lower end of the waterproof cover 4 can fit tightly with the inner wall of the middle part of the housing 1, which can effectively prevent water vapor from entering the waterproof cavity 5 and protect the light source assembly 2 from the influence of outdoor humid weather or rainy weather.

[0024] As a new implementation method, combined with the appendix Figure 2 and attached Figure 3 The waterproof lens assembly 3 includes a lens 31, a mounting cylinder 32 for mounting the lens 31, and adjusting screws 33 disposed on opposite sides of the mounting cylinder 32. The attachment edge 41 at the upper end of the waterproof cover 4 is linked to the lower end of the mounting cylinder 32. The mounting cylinder 32 has a cylindrical structure. The lens 31 is adapted to the mounting cylinder 32 and is fixedly installed inside the mounting cylinder 32. The waterproof lens assembly 3 can move up and down along the light output direction, and the waterproof cover 4 stretches or compresses with the movement of the waterproof lens assembly 3. The lower surface of the mounting cylinder 32 is provided with threaded holes that correspond one-to-one with the mounting holes 411 on the attachment edge of the waterproof cover 4. The waterproof cover 4 is fixed to the lower surface of the mounting cylinder 32 by fasteners. The tightness of the fasteners can be adjusted to make the attachment edge 41 fit tightly against the lower surface of the mounting cylinder 32. That is, when the waterproof lens assembly 3 moves, the attachment edge 41 can also fit tightly against the lower end of the mounting cylinder 32. The waterproof lens assembly 3 has a waterproof structure, which can effectively prevent water vapor from entering the interior of the waterproof lens assembly 3. When the waterproof cover 4 is tightly attached to the mounting cylinder 32, external water vapor cannot enter the interior of the waterproof cavity 5 from the waterproof lens assembly 3, nor can it enter the interior of the waterproof cavity 5 through the connection between the waterproof cover 4 and the mounting cylinder 32, thus forming a sealed waterproof cavity 5. The beneficial effect of this embodiment is that water vapor cannot enter the waterproof lens assembly 3, which can effectively prevent water mist from forming on the light-incident surface of the lens 31 inside the mounting cylinder 32, thus affecting the light output effect of the lamp; and the attachment edge 41 of the waterproof cover 4 is in close contact with the lower surface of the mounting cylinder 32, which can also prevent water vapor from entering the waterproof cavity 5 from the connection between the waterproof cover 4 and the mounting cylinder 32, thus preventing the light source assembly 2 from short-circuiting and burning out due to water vapor.

[0025] As a new implementation method, combined with the appendix Figure 3 The housing 1 also includes a mounting ear 12 located on the inner wall in the middle of the housing 1, and the attachment edge 41 at the lower end of the waterproof cover 4 is locked to the lower surface of the mounting ear 12. The mounting ear 12 is an annular plate, located between the mounting slot 11 and the light source assembly 2. The upper surface of the attachment edge 41 of the waterproof cover 4 is locked and fixed to the lower surface of the mounting ear 12, and the waterproof cover 4 is stretched or compressed with the movement of the waterproof lens assembly 3. When the waterproof cover 4 is stretched, the force on the attachment edge 41 is an upward force. If the lower surface of the attachment edge 41 at the lower end of the waterproof cover 4 is in close contact with the upper surface of the mounting ear 12, after repeated stretching, the attachment edge 41 of the waterproof cover 4 is prone to gap with the mounting ear 12, affecting the waterproof performance of the waterproof cavity 5. In this embodiment, the upper surface of the attachment edge 41 is in close contact with the lower surface of the mounting ear 12. When the waterproof cover 4 is stretched upward, a force is applied to the attachment edge 41 to make it press against the mounting ear 12. That is, after repeated stretching, there will be no gap between the attachment edge 41 of the waterproof cover and the mounting ear 12. The beneficial effect of this embodiment is that whether the waterproof cover 4 is stretched or compressed, it will not affect the tight fit between the attachment edge 41 and the mounting ear 12, thus forming a sealed waterproof cavity 5, which effectively prevents moisture from entering the waterproof cavity 5 from the connection between the waterproof cover 4 and the mounting ear 12.

[0026] As a new implementation method, combined with the appendix Figure 3 and attached Figure 4 The upper part of the outer shell 1 is provided with two elongated focusing holes 13 facing each other. The focusing holes 13 are used for adjusting the air gap screw 33. The mounting cylinder 32 is provided with mounting holes on both sides for installing the adjusting screw 33. The adjusting screw 33 is adapted to the mounting hole. The adjusting screw 33 is adapted to the focusing hole 13, and the adjusting screw 33 passes through the focusing hole 13 and is threadedly connected to the mounting hole. By adjusting the tightness of the engagement between the adjusting screw 33 and the mounting hole, the state of the waterproof lens assembly 3 is changed. That is, when the adjusting screw 33 is tightened, the waterproof lens assembly 3 is also in a locked state. At this time, one end of the adjusting screw 33 is in close contact with the outer shell 1, and the waterproof lens assembly 3 cannot move up and down along the light emission direction. When the adjusting screw 33 is loosened, the waterproof lens assembly 3 is also in an adjustable state. At this time, there is a gap between one end of the adjusting screw 33 and the outer shell 1, and the waterproof lens assembly 3 can move up and down along the light emission direction. In this embodiment, the focusing stroke of the focusing hole 13 is 31mm, that is, the waterproof lens assembly 3 can move up and down along the light emission direction within the 31mm stroke of the focusing hole 13. It can be understood that the focusing stroke of the focusing hole 13 can also be other values. The beneficial effect of this embodiment is that the waterproof lens assembly 3 can move up and down within the focusing stroke range of the focusing hole 13 along the light emission direction, thereby changing the size of the formed light spot and enriching the light emission effect of the lamp.

[0027] As a new implementation method, combined with the appendix Figure 2 and attached Figure 3 The mounting cylinder 32 is fitted into the mounting groove 11, the diameter of which is slightly larger than the diameter of the mounting cylinder 32. The mounting groove 11 is a circular groove, and the mounting cylinder 32 is adapted to fit into it. The mounting cylinder 32 has a stepped cylindrical structure, and its maximum outer diameter is slightly smaller than the diameter of the mounting groove 11. When the waterproof lens assembly 3 moves up and down along the light emission direction, the mounting cylinder 32 and the mounting groove 11 will not interfere with each other, thus not affecting the focusing of the waterproof lens assembly 3. The beneficial effect of this embodiment is that the waterproof lens assembly 3 can move smoothly up and down within the mounting groove 11, which facilitates more convenient adjustment of the light spot size.

[0028] As a new implementation method, combined with the appendix Figure 3 The outer shell 1, waterproof cover 4, focusing hole 13, and mounting groove 11 together form a drainage channel 6 that communicates with the outside. The drainage channel 6 is located on the upper part of the waterproof cavity 5, and the outer shell 1 covers the drainage channel 6. There is a gap between the mounting groove 11 and the mounting cylinder 32, allowing external moisture to easily enter the interior of the outer shell 1 through the gap between the mounting groove 11 and the mounting cylinder 32. The focusing hole 13 connects the interior of the outer shell 1 with the outside, allowing external moisture to enter the interior of the outer shell as well. When a waterproof cover 4 is installed inside the outer shell, moisture entering from the outside can only remain outside the waterproof cavity 5, forming a drainage channel 6. That is, the moisture remaining in the drainage channel 6 can be discharged through the gap between the mounting groove 11 and the waterproof lens assembly 3, or through the focusing holes 13 symmetrically distributed on the upper part of the outer shell, preventing moisture from remaining inside the outer shell 1 for a long time and causing internal parts to rust. The beneficial effect of this embodiment is that the mounting groove 11 and focusing hole 13 on the outer shell facilitate the rapid discharge of moisture remaining outside the waterproof cavity 5 from the exterior of the outer shell 1.

[0029] As a new implementation method, combined with the appendix Figure 3 The thickness of the waterproof cover 4 ranges from 1mm to 3mm. When the thickness of the waterproof cover 4 is less than 1mm, the waterproof lens assembly 3 slides down rapidly when entering the adjustment state, meaning the waterproof cover 4 cannot provide sufficient support for the waterproof lens assembly 3, making focusing and positioning of the waterproof lens assembly 3 difficult. Furthermore, an excessively thin waterproof cover 4 is prone to damage during stretching, allowing moisture to enter the waterproof cavity 5. When the thickness of the waterproof cover 4 is greater than 3mm, downward focusing of the waterproof lens assembly 3 encounters significant resistance, meaning the waterproof cover 4 is difficult to compress due to its excessive thickness, which is detrimental to focusing the lamp. The beneficial effect of this implementation is that when the thickness of the waterproof cover 4 is within the range of 1-3mm, the waterproof cover 4 can provide sufficient support for the waterproof lens assembly 3, preventing it from sliding down rapidly during adjustment, and can also be easily compressed downwards, making the focusing process of the waterproof lens assembly 3 smoother.

[0030] As a new implementation method, combined with the appendix Figure 2 The waterproof cover 4 is made of materials including, but not limited to, silicone and rubber. Silicone and rubber both possess excellent elasticity, improving the fit between the waterproof cover 4 and the mounting ears 12 on the waterproof lens assembly and housing. Silicone and rubber have a very wide heat resistance range, allowing them to operate for extended periods in high-temperature environments without melting or deforming. During outdoor performances, lighting fixtures are exposed to sunlight for extended periods; high-quality silicone and rubber offer excellent UV resistance and oxidation resistance, ensuring long-term use without aging, powdering, or cracking. In this embodiment, the waterproof cover 4 is made of silicone. The advantage of this embodiment is that using silicone for the waterproof cover 4 effectively prevents aging or deformation caused by prolonged exposure to complex outdoor environments, ensuring that the waterproof performance of the waterproof cavity 5 remains unaffected.

[0031] As a new implementation method, combined with the appendix Figure 3 The light source assembly 2 includes a light source 21, a condenser lens 22 located directly above the light source 21, and a pattern disk 23. The light source assembly 2 is installed at the bottom of the waterproof cavity 5. Both the condenser lens 22 and the pattern disk 23 are located in the light-emitting direction of the light source 21. The condenser lens 22 collects the light emitted from the light source, maximizing the luminous flux generated by the light source 21, so that the light emitted from the light source 21 can be projected onto the image in the pattern disk 23, forming a light spot with a clear pattern. The location of the light source assembly 2 at the bottom of the waterproof cavity 5 prevents interference between the waterproof lens assembly 3 and the light source assembly 2 when the waterproof lens assembly 3 is focusing. The beneficial effect of this embodiment is that the light source assembly 2 is installed inside the waterproof cavity 5, effectively avoiding external moisture interference that could affect its normal operation.

[0032] 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 4 As shown, the waterproof lens assembly 3 changes its state by adjusting the tightness of the adjusting screw 33; this allows the waterproof lens assembly 3 to focus within the range of the focusing hole 13 along the light output direction, or the waterproof lens assembly 3 to be in a locked state, at which time the waterproof lens assembly 3 is fixedly sleeved in the mounting through groove 11; the attachment edge 41 at the upper end of the waterproof cover 4 is linked to the lower surface of the mounting cylinder 32, and the attachment edge 41 at the lower end of the waterproof cover 4 is attached to the lower surface of the mounting ear 12. The waterproof cover 4, the waterproof lens assembly 3, and the outer shell 1 together form a waterproof cavity 5, which can also protect the light source assembly 2 from outdoor humid weather or rainy weather when the lamp is focusing.
