Description

Technical Field

[0001] The present application relates to the technical field of projection lamps, and in particular to a high-power waterproof and fog-proof optical projection lens. Background Art

[0002] With the rise of the cultural tourism industry, more and more cities are adopting outdoor lighting for their lighting needs, placing higher demands on the use of lighting fixtures, such as waterproofing, fog resistance, and anti-fouling. Furthermore, indoor stages and theaters often use fog, and regular cleaning of the fixtures also requires strict anti-fouling and anti-scratch protection of the light-emitting lens. Furthermore, high-end pattern projection lamps generally use optical lenses, which are subject to increasingly stringent requirements in harsh operating environments.

[0003] Currently, the light-emitting lens of lamps is generally waterproofed only by using glue or sealant at the exit end of the lens. The anti-fouling, anti-scratch and anti-fog performance is poor, and the lens is easily scrapped, which increases the maintenance cost of the lamp in the later stage and wastes resources. Utility Model Content

[0004] In order to improve the practicality and sealing performance of a projection lens, the present application provides a high-power waterproof and fog-proof optical projection lens.

[0005] This application provides a high-power waterproof and fog-proof optical projection lens, which adopts the following technical solutions:

[0006] A high-power waterproof and fog-proof optical projection lens comprises a lens barrel, a light-emitting lens being provided at the light-emitting end of the lens barrel, an outer wall of the light-emitting lens being provided with a waterproof and fog-proof film layer, a first sealing ring being pressed against one side of the waterproof and fog-proof film layer, and a gap between the lens barrel and the light-emitting lens being sealed by the first sealing ring; a light-incident lens being provided at one end of the lens barrel away from the light-emitting lens, a second sealing ring being pressed against one side of the light-incident lens, and a gap between the lens barrel and the light-incident lens being sealed by the second sealing ring.

[0007] By adopting the above technical solution, a waterproof and anti-fog film layer is provided on the outer wall of the light-emitting lens to protect the light-emitting lens, thereby improving the lens's ability to resist scratches, water, fog and mildew. The first sealing ring and the second sealing ring are used for sealing to improve the sealing performance of the lens. The combination of functions enables the lens sealing performance to reach the IP67 protection level, reduces the possibility of the lens being scrapped, and thus improves the practicality and sealing performance of the projection lens.

[0008] Optionally, the light-emitting lens is a tempered lens.

[0009] By adopting the above technical solution, the anti-scratch function is enhanced and the possibility of lens scrapping is further reduced.

[0010] Optionally, the lens barrel is detachably connected to a first fixing component, and the first fixing component is used to press tightly against the first sealing ring to fix the light-emitting lens to the lens barrel.

[0011] By adopting the above technical solution, the first sealing ring is easily damaged after long-term use. The first sealing ring can be disassembled from the lens through the first fixing assembly, so that the first sealing ring can be replaced, thereby improving the sealing effect of the lens. In addition, the sealing ring is provided to achieve sealing by compression rather than sealing the lens by sealing adhesion, thereby reducing the possibility of the lens being scrapped during disassembly due to sealing adhesion, thereby further improving the practicality of the projection lens.

[0012] Optionally, the first fixing assembly includes a first pressing piece and a first locking ring, the first pressing piece is pressed against the first sealing ring, the first pressing piece is pressed against the first locking ring, and the first locking ring is fixed to the lens barrel.

[0013] By adopting the above technical solution, the combined use of the first pressure plate and the first locking ring can effectively fix the sealing ring in an appropriate position, reducing the possibility of movement or offset inside the lens, thereby improving the sealing performance of the lens and the stability of the overall structure, as well as reducing the possibility of external factors such as dust and moisture intruding into the interior of the lens, thereby protecting the optical elements inside the lens from damage.

[0014] Optionally, the first locking ring is provided with a first locking groove, a first locking piece is provided on one side of the first locking ring, the first locking piece is inserted into the first locking groove, the first locking piece is abutted against the first locking ring, and the first locking piece is threadedly connected to the lens barrel.

[0015] By adopting the above technical solution, the cooperation between the locking groove of the first locking ring and the first locking member, plus the use of a threaded connection, acts together on the lens barrel, effectively preventing the lens from loosening due to vibration or external force during use, thereby improving the stability and safety of the lens.

[0016] Optionally, the lens barrel is detachably connected to a second fixing component, and the second fixing component is used to press tightly against the second sealing ring to fix the light incident lens to the lens barrel.

[0017] By adopting the above technical solution, the second sealing ring can be easily replaced, thereby further improving the practicality and sealing performance of the lens.

[0018] Optionally, a transition lens is provided between the light-emitting lens and the light-incoming lens, and the transition lens is installed on the lens barrel. One side of the transition lens is against one side of the light-incoming lens, and there is a gap between the transition lens and the light-emitting lens. The diameter of the light-emitting lens is larger than the diameter of the transition lens.

[0019] By adopting the above technical solution, the reflection of light between the light-emitting lens and the transition lens is reduced.

[0020] Optionally, the side of the light input lens away from the light output lens is concave, and a pressing surface is provided between the outer ring wall of the light input lens and the concave side of the light input lens. The pressing surface is planar, and the second sealing ring is pressed against the pressing surface.

[0021] By adopting the above technical solution and providing a pressing surface, the possibility of the second sealing ring falling off the light incident lens is reduced, the stability of the installation of the second sealing ring is improved, and thus the sealing effect of the lens is improved.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. A waterproof and anti-fog film layer is provided on the outer wall of the light-emitting lens to protect the light-emitting lens, thereby improving the lens's ability to resist scratches, water, fog, and mildew. A first sealing ring and a second sealing ring are used for sealing to improve the lens's sealing performance. The combined functions enable the lens's sealing performance to reach the IP67 protection level, reducing the possibility of lens scrapping, thereby improving the practicality and sealing of the projection lens;

[0024] 2. Enhanced anti-scratch function to further reduce the possibility of lens scrapping;

[0025] 3. The combined use of the first pressure plate and the first locking ring can effectively secure the sealing ring in place, reducing the possibility of movement or displacement inside the lens, thereby improving the sealing performance of the lens and the stability of the overall structure. In addition, it can reduce the possibility of external factors such as dust and moisture intruding into the interior of the lens, thereby protecting the optical components inside the lens from damage.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiments of the present application disclose a high-power waterproof and fog-proof optical projection lens.

[0033] Example 1

[0034] Reference Figure 1 A high-power waterproof and fog-proof optical projection lens includes a lens barrel 1, a light-emitting lens 2 is fixedly installed on the light-emitting end of the lens barrel 1, and the outer wall of the light-emitting lens 2 facing the outside of the lens is coated with a waterproof and fog-proof film layer 3, and a first sealing ring 4 is pressed on the side of the waterproof and fog-proof film layer 3 away from the light-emitting lens 2, and the gap between the lens barrel 1 and the light-emitting lens 2 is sealed by the first sealing ring 4; a light-incoming lens 5 is fixedly installed on the light-incoming end of the lens barrel 1 away from the light-emitting lens 2, and a second sealing ring 6 is pressed on one side of the light-incoming lens 5, and the gap between the lens barrel 1 and the light-incoming lens 5 is sealed by the second sealing ring 6. Preferably, the waterproof and fog-proof film layer 3 can adopt NSG's anti-fog coating, XN-501A anti-fog coating or PET anti-fog film, which can be selected according to actual application.

[0035] A waterproof and anti-fog film layer 3 is plated on the light-emitting lens 2, making the light-emitting lens 2 hydrophobic, anti-fouling and anti-scratch. In addition, a first sealing ring 4 and a second sealing ring 6 are respectively used at both ends of the lens barrel 1 for sealing, further enhancing the lens's scratch resistance, waterproofness, anti-fog and anti-mildew properties. The lens's sealing performance can reach the IP67 protection level, reducing the possibility of lens scrapping, thereby improving the practicality and sealing of the projection lens.

[0036] Reference Figure 2 The lens barrel 1 is detachably connected to a first fixing component, which is used to press tightly against the first sealing ring 4 to fix the light-emitting lens 2 to the lens barrel 1. The first fixing component enhances the firmness of the fixation of the light-emitting lens 2. At the same time, the first fixing component can realize the disassembly and assembly function of the first sealing ring 4 and the light-emitting lens 2.

[0037] The first locking ring 42 is inserted into the positioning groove 411 so that the first pressing piece 41 is stably located between the lens barrel 1 and the first locking ring 42, thereby reducing the possibility of the first pressing piece 41 shifting when the first sealing ring 4 is pressed.

[0038] The first locking ring 42 is provided with a first locking groove, and a first locking piece 43 is provided on one side of the first locking ring 42. The first locking piece 43 is inserted into the first locking groove, and one side of the first locking piece 43 is abutted against one side of the first locking ring 42. A first threaded groove matching the first locking piece 43 is provided on one side of the light-emitting end of the lens barrel 1, and the end of the first locking piece 43 away from the first locking ring 42 is inserted into the first threaded groove. The first locking piece 43 is threadedly connected to the lens barrel 1. In this example, the first locking piece 43 is a bolt.

[0039] When installing the light-emitting lens 2, place the light-emitting lens 2 in the first mounting groove 11, and the side of the light-emitting lens 2 away from the waterproof and anti-fog film layer 3 is against the groove wall of the first mounting groove 11, and the first sealing ring 4 is placed on the side of the waterproof and anti-fog film layer 3, and the first pressing piece 41 is against the first sealing ring 4, and the first locking ring 42 is put on the lens barrel 1, and the first locking ring 42 is against the end of the first pressing piece 41 away from the first sealing ring 4, and the first locking piece 43 is inserted into the first locking groove and the first thread groove in sequence, and the first locking piece 43 is threadedly connected to the lens barrel 1, and the first locking piece 43 is tightened, so that the first sealing ring 4 is pressed tightly against the waterproof and anti-fog film layer 3.

[0040] Reference Figure 1 and Figure 3 The lens barrel 1 is detachably connected to a second fixing assembly, which is used to press tightly against the second sealing ring 6 to fix the light incident lens 5 to the lens barrel 1. The second fixing assembly includes a second pressing piece 61 and a second locking ring 62, as well as a second locking member 63 for fixing the second locking ring 62. The fixing structure of the light incident lens 5 is consistent with the fixing structure of the light output lens 2, and will not be described in detail here.

[0041] A transition lens 7 is provided between the light-emitting lens 2 and the light-entering lens 5. The transition lens 7 is mounted on the lens barrel 1. A second mounting groove 12 is provided on the inner wall of the light-entering end of the lens barrel 1. The transition lens 7 abuts against the groove wall of the second mounting groove 12 away from the light-entering end, thereby limiting the position of the transition lens 7 in the lens barrel 1. The side of the transition lens 7 away from the light-emitting lens abuts against the side of the light-entering lens 5. Both sides of the transition lens 7 abutting against the light-entering lens 5 are flat, and the side of the transition away from the light-entering lens 5 is convex. There is a gap between the transition lens 7 and the light-emitting lens 2. The lens barrel 1 is horn-shaped, the diameter of the transition lens 7 is equal to the diameter of the light incident lens 5, and the diameter of the light output lens 2 is greater than the diameter of the transition lens 7, which reduces the reflection of light between the light output lens 2 and the transition lens 7, so that the projection light can be effectively utilized.

[0042] The side of the light input lens 5 away from the light output lens 2 is concave, and a pressing surface 51 is provided between the outer ring wall of the light input lens 5 and the concave side of the light input lens 5. The pressing surface 51 is flat, and the second sealing ring 6 is pressed against the pressing surface 51, reducing the possibility of the second sealing ring 6 and thus the light input lens 5 falling, thereby improving the sealing performance of the light input lens 5.

[0043] The implementation principle of Example 1 of the present application is as follows: a waterproof and anti-fog film layer 3 is plated on the outer wall of the light-emitting lens 2, and the light-emitting lens 2 is vacuum-coated so that the light-emitting lens 2 has the functions of being hydrophobic, anti-fouling and anti-scratch, and the sealing performance is improved. A first sealing ring 4 and a second sealing ring 6 are respectively used at both ends of the lens barrel 1 for sealing, thereby further enhancing the purpose of the lens being scratch-proof, waterproof, anti-fog and anti-mildew, so that the sealing performance of the lens can reach the IP67 protection level, reducing the possibility of the lens being scrapped, thereby improving the practicality and sealing performance of the projection lens.

[0044] Example 2

[0045] Preferably, in order to enhance the anti-scratch function, the light-emitting lens 2 is a tempered lens. By tempering the lens, the possibility of lens scrapping is further reduced.

[0046] The implementation principle of Example 2 of the present application is: using tempered lenses to further reduce the possibility of lens scrapping.

[0047] The above are all preferred embodiments of the present application. These embodiments are only explanations of the present application and do not limit the scope of protection of the present application in turn. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
