Description

Technical Field

[0001] This utility model belongs to the field of optical equipment technology, and specifically relates to a dustproof and protective structure for an LDLS light source. Background Technology

[0002] In the application scenarios of LDLS (Laser Driven Light Source), the stable installation of its core component, the discharge lamp chamber, and its overall dustproof performance are crucial. Existing LDLS light source structures have several shortcomings: Firstly, the fixing method of the discharge lamp chamber within the mounting cavity is relatively simple, lacking an effective fixing device. This makes the discharge lamp chamber prone to loosening and displacement under vibration, impact, or long-term use, thus affecting the light source's luminous efficacy and stability, and potentially even damaging the light source and shortening its lifespan. Secondly, existing LDLS light sources have deficiencies in dustproof protection. Dust and other impurities can easily enter the light source and adhere to key components such as the discharge lamp chamber and lenses, affecting light propagation and focusing, reducing the light source's output power and beam quality, and also increasing the frequency and cost of equipment maintenance.

[0003] Therefore, developing an LDLS light source structure that can effectively stabilize the discharge lamp chamber and has good dust protection performance has become an urgent technical problem to be solved in this field. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a dustproof protection structure for LDLS light sources to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a dustproof protection structure for an LDLS light source, comprising: an LDLS light source body, the LDLS light source body including a mounting cavity and a cover plate, the mounting cavity being provided with a discharge lamp chamber and four mounting posts, each of the four mounting posts having a first threaded hole, a fixing plate being fitted onto the discharge lamp chamber, the fixing plate being provided with four connecting blocks, each of the four connecting blocks having a second threaded hole, the four second threaded holes being coaxially aligned with the corresponding first threaded holes and connected by fastening bolts, and a lens and a protective cover being provided on the cover plate.

[0006] As further explained, a sealing ring is fitted on the outer edge of the cover plate, and the mounting cavity and the cover plate are detachably connected by bolts.

[0007] As a further explanation, the inner ring of the fixing plate is provided with an elastic ring for holding the discharge lamp chamber tightly.

[0008] As further explained, the cover plate has a threaded groove on the outer ring of the lens.

[0009] As further explained, the protective cover includes a threaded cylinder that is threadedly connected to the threaded groove, one end of the threaded cylinder having an outer end seat, and the outer ring of the outer end seat having a flip cover that can be used to cover its port.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention features a fixed plate installed outside the discharge lamp chamber. Four connecting blocks on the fixed plate correspond to four mounting posts inside the mounting cavity. The second threaded holes of the connecting blocks are coaxially aligned with the first threaded holes of the mounting posts and then locked with fastening bolts, forming a precise and robust fixing structure. This replaces the existing simple fixing method, effectively avoiding the problems of loosening and displacement of the discharge lamp chamber caused by equipment vibration, collision, and long-term use. It ensures the precise laser focusing position, guarantees the stability and luminous effect of the light source, avoids damage to the light source caused by component displacement, and significantly extends the service life of the discharge lamp chamber and the overall light source.

[0011] A sealing ring is embedded on the outer edge of the cover plate, which, together with the bolts connecting the cover plate to the mounting cavity, can be detachably connected. This effectively prevents external dust and impurities from entering the mounting cavity and avoids dust adhering to core components such as the discharge lamp chamber. At the same time, a threaded groove is opened on the outer ring of the cover plate lens, and the protective cover is connected to the threaded groove through a threaded cylinder. The hinged flip cover at the outer end seat can provide double protection for the lens, preventing the protective cover from falling off and enabling the lens to be normally dustproofed by opening and closing the flip cover. This prevents dust from adhering and affecting light propagation and focusing, ensuring stable output power and beam quality of the light source, significantly reducing the frequency of equipment maintenance and lowering subsequent maintenance costs.

[0012] The overall structure integrates both fixing and dustproof functions around the LDLS light source body, with no redundant parts. An elastic ring is added to the inner ring of the fixing plate, which can not only further tighten the discharge lamp chamber to enhance the fixing effect, but also adapt to the outer diameter of the discharge lamp chamber through elastic deformation, avoiding damage to components caused by rigid fixing. The cover plate and the mounting cavity are connected by bolts for easy disassembly, and the protective cover and the cover plate are matched by threads, making disassembly and assembly simple and convenient for subsequent inspection and replacement of internal discharge lamp chamber, external lens and other components, improving the ease of use of the equipment.

[0013] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention are realized and obtained through the structures particularly pointed out in the description and the accompanying drawings.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figure 1-2A dustproof protection structure for an LDLS light source includes: an LDLS light source body 1, which includes a mounting cavity 2 and a cover plate 3. Based on the LDLS light source body 1, the mounting cavity 2 supports the core components, and the cover plate 3 provides closed protection, forming a basic dustproof protection frame that provides both support and enclosure, thus structurally isolating external dust intrusion channels. The mounting cavity 2 contains a discharge lamp chamber 4 and four mounting posts 5. Each of the four mounting posts 5 has a first threaded hole 51. A fixing plate 6 is fitted onto the discharge lamp chamber 4, and four connecting blocks 7 are provided on the fixing plate 6. Each of the four connecting blocks 7 has a... The second threaded hole 71, the four second threaded holes 71 are respectively coaxially aligned with the corresponding first threaded hole 51 and connected by fastening bolts. The four connecting blocks 7 of the fixing plate 6 correspond one-to-one with the four mounting posts 5 in the mounting cavity 2. By using the coaxial alignment of the second threaded hole 71 with the first threaded hole 51 and locking it with fastening bolts, a rigid fixing structure is formed, realizing the precise positioning and stable installation of the discharge lamp chamber 4. The cover plate 3 is provided with a lens 8 and a protective cover 10. The cover plate 3 integrates the optical path output lens 8 and is also equipped with a protective cover 10 to provide basic protection for the lens 8, prevent dust from directly adhering, and ensure smooth optical path transmission.

[0020] This solution effectively addresses the loosening and displacement issues caused by the simple fixing of the existing discharge lamp chamber 4. The coaxial threaded fastening ensures high fixing accuracy and strong stability, resisting equipment vibration, collisions, and long-term wear and tear. It ensures precise laser focusing, guarantees the luminous effect and stability of the LDLS light source body 1, prevents component damage, and extends service life. Combined with a dedicated protective cover 10 for the lens 8, it reduces dust ingress and adhesion to critical components, initially resolving existing dustproof deficiencies, ensuring light propagation and focusing effects, and maintaining the light source's output power and beam quality.

[0021] A sealing ring 31 is embedded in the outer edge of the cover plate 3, and the mounting cavity 2 and the cover plate 3 are detachably connected by bolts. The sealing ring 31 embedded in the outer edge of the cover plate 3, together with the bolts, realizes the detachable connection between the mounting cavity 2 and the cover plate 3. The sealing ring 31 fills the connection gap between the cover plate 3 and the mounting cavity 2, forming a sealing barrier to prevent dust from entering the interior from the connection gap between the cover plate 3 and the mounting cavity 2.

[0022] An elastic ring 61 is provided on the inner ring of the fixing plate 6 to hold the discharge lamp chamber 4 tightly. Utilizing the elastic deformation characteristics of the elastic ring 61, it fits against the outer wall of the discharge lamp chamber 4 to achieve a tight fixation, forming a dual fixing structure of "rigid fixation and elastic clamping". The elastic ring 61 itself has buffering properties, which can absorb the slight vibrations generated by the operation of the equipment and avoid damage caused by hard contact between the fixing plate 6 and the discharge lamp chamber 4.

[0023] The cover plate 3 has a threaded groove 9 on the outer ring of the lens 8. The threaded groove 9 is machined around the lens 8 on the cover plate 3, providing a reliable and repeatedly removable mechanical interface for the protective cover 10. This solves the problem of existing protective covers 10 lacking a fixed installation base and being prone to falling off. The threaded groove 9 provides a dedicated installation position for the protective cover 10, making it firmly installed, not easy to loosen or fall off, and ensuring the continuity of protection for the lens 8.

[0024] The protective cover 10 includes a threaded cylinder 101 threadedly connected to the threaded groove 9. One end of the threaded cylinder 101 is provided with an outer end seat 102, and the outer ring of the outer end seat 102 is hinged with a flip cover 103 for covering its port. The protective cover 10 is threadedly connected to the threaded groove 9 through the threaded cylinder 101, achieving a secure installation of the protective cover 10. At the same time, the threaded fit provides a certain degree of sealing, reducing dust intrusion from the installation gap. The outer ring of the outer end seat 102 is hinged to the flip cover 103, which can be opened and closed flexibly. When not in use, it covers the port, forming a secondary dust protection for the lens 8; when in use, it is flipped open without affecting the optical path output, does not obstruct the light path during use, and provides effective protection when not in use.

[0025] All components selected in this application (parts whose specific structures are not described) are general standard parts or parts known to those skilled in the art, and their structures and principles can be obtained by those skilled in the art through technical manuals. This knowledge can be obtained through conventional experimental methods.
