Description

Technical Field

[0001] The present invention relates to the technical field of laser fiber lights, and specifically relates to a three-proof fiber light and a preparation method thereof. Background Art

[0002] The main part of a fiber light is a coupled laser. Existing coupled laser packaging components are numerous, with a slightly larger and single size, and often welding technology is used for packaging to ensure its stability. Nowadays, the development trend is to manufacture coupled lasers with smaller external dimensions and easier replacement.

[0003] Currently, when manufacturing coupled laser devices using the indirect coupling method, the volume of some products is still relatively large, and the wavelengths cannot be diversified in the same module. At the same time, there are many packaging components, which are not convenient for carrying and assembling, and are not conducive to the integration of the optical system, resulting in high manufacturing costs.

[0004] And because coupling requires the fiber to enter the inside of the package to align with the laser, its coupling efficiency is easily affected by the distance between the laser and the fiber end face. Therefore, existing small-sized coupled fiber lasers also have the problem of unstable coupling efficiency.

[0005] Moreover, most existing fiber lights use LEDs as light sources and plastic optical fibers for transmission. Due to the large volume of the LED and the non-concentrated light source, after being focused by a lens, the light spot is large and cannot be accurately focused inside the fiber core end face, resulting in low transmission efficiency. When the light cannot be transmitted smoothly, heat is generated. After the heat accumulates, the fiber end face is burned. After being burned, it is more difficult for the light to be transmitted out, and the accumulation of heat may cause a fire, posing a safety hazard.

[0006] Therefore, in order to solve the above problems, it is particularly important to design a three-proof fiber light and a preparation method thereof. Summary of the Invention

[0007] In order to solve the above problems, the present invention designs a three-proof fiber light and a preparation method thereof, integrating multiple coupled lasers in a housing body, which has the advantages of compact structure, small volume, and high energy conversion efficiency. Moreover, the power of a single light beam is small and the energy is low, making it not easy to generate high temperature, thus avoiding the occurrence of fire. After being conducted by one-to-one optical fibers and then using multiple optical fibers together according to the required light intensity, it can be applied to special occasions and scenarios such as fire prevention, lightning protection, and waterproofing.

[0008] To solve the above technical problems, the present invention provides a three-proof optical fiber lamp, characterized in that: the three-proof optical fiber lamp is integrated by a laser diode; among them, the three-proof specifically refers to lightning protection, fire protection, and waterproofing; the three-proof optical fiber lamp includes a housing, a packaged heat sink, a light-emitting chip, a first lens holder, a second lens holder, a first threaded lens holder, a second threaded lens holder, a first aspherical lens, and a second aspherical lens. A number of first lens holders are sequentially fixed at the bottom inside the housing from left to right. A packaged heat sink and a light-emitting chip are installed inside the lower end of the first lens holder. The upper end of the first lens holder is connected to the first threaded lens holder. A first aspherical lens is adhesively bonded to a specified position on the first threaded lens holder with glue. A number of second lens holders are also sequentially fixed at the top of the housing from left to right. The number of the second lens holders is the same as the number of the first lens holders. A second lens holder is provided directly above each first lens holder.

After filling a certain amount of pressurized gas, close the pressurized gas pipeline, and judge the airtightness situation by observing the change of the pressure gauge set on the airtightness test intake pipeline;

[0020] A3: After the pressure gauge shows no change in the process of 10 - 15 s, connect the airtightness test exhaust pipeline to the automatic sealing valve set on the other side of the outer housing, and control the airtightness test intake pipeline to be connected to the inert gas pipeline;

[0021] A4: Fill the outer housing with inert gas through the inert gas pipeline, use the inert gas to discharge the pressurized gas.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] As Figure 1 and Figure 2A three-proof optical fiber lamp as shown, the three-proof optical fiber lamp is integrated by a laser diode, where the three proofs specifically refer to lightning protection, fire protection, and waterproofing; the three-proof optical fiber lamp includes a housing 10, a packaged heat sink 9, a light-emitting chip 8, a first lens holder 7, a second lens holder 2, a first threaded lens holder 6, a second threaded lens holder 3, a first aspheric lens 5, and a second aspheric lens 4. A number of first lens holders are sequentially fixed at the bottom inside the housing from left to right. A packaged heat sink and a light-emitting chip are installed inside the lower end of the first lens holder. The upper end of the first lens holder is connected to the first threaded lens holder. The first aspheric lens is adhesively bonded to a specified position on the first threaded lens holder. A number of second lens holders are also sequentially fixed at the top of the housing from left to right. The number of the second lens holders is the same as the number of the first lens holders. A second lens holder is provided directly above each first lens holder. The second aspheric lens is adhesively bonded to a specified position at the lower end of the second threaded lens holder. The second threaded lens holder is connected to the second lens holder. After the present invention adopts the above design, the number of packaged components can be greatly reduced, its assembly and disassembly are simpler, it is convenient to replace when the optical fiber has problems, and the manufacturing cost is effectively reduced. The present invention integrates multiple coupled lasers inside the housing, which has the advantages of compact structure, small volume, and high energy conversion efficiency. Moreover, the power of a single beam is small and the energy is low, so it is not easy to generate high temperature, thus avoiding the occurrence of fire. After being conducted through one-to-one optical fibers and then using multiple optical fibers together according to the required light intensity, it can be applied to special occasions and scenarios such as fire protection, lightning protection, and waterproofing.

[0035] The present invention uses a laser diode with a power not greater than 500 milliwatts as the light source. In the industry, it is stipulated that a power greater than 500 milliwatts will pose a fire hazard. Through this design, the safety hazard is reduced; the present invention also couples the laser source to a glass optical fiber and utilizes the transmission characteristics of the glass optical fiber to transmit light to places dozens of meters, hundreds of meters, or even thousands of meters away, and then uses methods such as lenses and reflection to scatter or project the focused light of the laser beam to achieve lighting, indication, and warning; and the present invention uses multiple low-power laser diodes coupled to a single glass optical fiber, with an extremely small light spot, precisely concentrated on the core diameter. Because the power is only dozens to hundreds of milliwatts, the heat is very low and the light input end face of the optical fiber will not be burned, so it can be used for a long time, extending the service life.

[0036] As Figure 1 Shown, there are twelve first lens holders and second lens holders respectively. The upper end of the second lens holder is provided with a threaded structure, and the threaded structure at the upper end of the second lens holder extends out of the housing and is respectively connected to a flange structure 1.

[0037] Glue is applied at the connection between the first threaded lens holder and the first lens holder, and at the connection between the second threaded lens holder and the second lens holder. Thread sealant is applied at the threaded part where the second lens holder is connected to the flange structure.

[0038] The present invention also provides a preparation method for a three-proof optical fiber lamp, which specifically includes the following steps:

[0039] S1: Install the encapsulated heat sink and the light-emitting chip inside one end of the first lens holder and encapsulate this end through an encapsulation device. Horizontally bond the first aspherical lens at the specified position on the first threaded lens holder using 353 glue, then screw the first threaded lens holder onto the first lens holder, light up the encapsulated light-emitting chip, and adjust the light spot by rotating the first threaded lens holder to achieve a collimated light beam. After the adjustment is completed, apply glue at the connection between the first threaded lens holder and the first lens holder, and repeat the above steps twelve times to complete the assembly of the first lens holder assembly;

[0040] S2: Apply thread glue at the thread of the second lens holder, screw the flange structure of the FC / PC flange onto the second lens holder, then install the second aspherical lens on the second threaded lens holder using glue. After fixing, screw the second threaded lens holder onto the second lens holder, pass light at the FC / PC flange, and rotate the threaded lens holder 3 to adjust the light spot to achieve a collimated light spot. After the adjustment is completed, repeat the above steps twelve times to complete the assembly of the second lens holder assembly;

[0041] S3: After steps S1 and S2 are completed, install the assembled twelve first lens holder assemblies and twelve second lens holder assemblies at the specified positions on the outer housing;

By analogy, complete the debugging of the remaining twelve second threaded lens holders;

[0043] S5: After the debugging in step S4 is completed, seal the outer housing and conduct an airtightness test on it. After passing the test, fill it with inert gas for protection.

[0044] The specific steps of the airtightness test in the above step S5 are as follows:

[0045] A1: Connect the airtightness test intake pipe to the automatic sealing valve provided on one side of the outer housing through the cooperation of internal and external thread structures;

[0046] A2: Control the airtightness test intake pipe to be connected to the pressurized gas pipe, fill the outer housing with pressurized gas through the pressurized gas pipe, close the pressurized gas pipe after filling a certain amount of pressurized gas, and judge the airtightness situation by observing the change of the pressure gauge provided on the airtightness test intake pipe;

[0047] A3: After the pressure gauge shows no change in the process of 10 - 15 s, connect the airtightness detection outlet pipeline to the automatic sealing valve set on the other side of the outer shell, and control the airtightness detection inlet pipeline and the inert gas pipeline;

[0048] A4: Fill the outer shell with inert gas through the inert gas pipeline, use the inert gas to discharge the pressurized gas, remove the airtightness detection inlet pipeline and the airtightness detection outlet pipeline after inflating for 5 - 10 s, and automatically seal the outer shell through the automatic sealing valve.

An overflow channel is opened on the pressing plate. The resin injection gun is connected to a resin injection pump 18 through an injection hose. A flow meter 19 is arranged at the connection of the injection hose and the resin injection pump. The resin injection pump is communicated with the discharge port of the resin heat preservation storage tank. Set the first lens holder set installed with the heat sink and the light - emitting chip on the positioning lower plug. The lower end of the first lens holder is sealed by the positioning lower plug. Then, the resin injection gun fills resin into the upper end of the first lens holder. After filling a certain amount, start the lower pressing cylinder and use the pressing plate to compact the resin in the first lens holder. After the resin cools down, the heat sink and the light - emitting chip in the first lens holder are encapsulated.

[0050] As Figure 3 The positioning lower plug shown in the figure consists of a guide post and a lower plug. A guide hole matching the guide post is opened at the bottom of the lower plug. The lower end of the guide post is vertically arranged on the top of the bottom plate. The upper end of the guide post extends into the guide hole and is connected to the lower plug through a spring.

[0053] A three-proof optical fiber lamp provided by the present invention as described above can be used as a warning lamp on the blade of a wind turbine. Warning lamps are provided on both the front and back sides of the blade end to play a warning role. With the improvement of production technology, the blades of wind turbines are getting larger and larger, reaching 100-200 meters or even longer. Therefore, it becomes particularly important to install aviation warning lamps. In order to avoid lightning strikes, optical fiber lamps without conductors come in handy. A total of 72 laser diodes and 72 optical fibers are shared on the three blades, with 24 optical fibers used on each blade. These 24 optical fibers are made into a 24-core optical cable, and the optical cable is laid in a snake shape to eliminate the centrifugal force generated by the rotation of the blade. The 24 optical fibers are divided into two parts, with 12 on each side of the blade. The light beam is projected or scattered through a lens or reflection.

[0054] A three-proof optical fiber lamp provided by the present invention as described above can be used as a landscape lighting lamp on ancient buildings. Since ordinary lighting requires power supply, once the laid wires are short-circuited or struck by lightning, the consequences of fire are very serious. Therefore, using this design can avoid the occurrence of fire.

[0055] A three-proof optical fiber lamp provided by the present invention as described above can be used as a runway lamp on an airport and an indicator lamp on the ground. Conventional runway lamps or ground indicator lamps use bulbs or LED lights as the power supply and light-emitting points. Bulbs and LED lights may be damaged due to electronic components and LEDs, and at the same time, the power supply lines may also fail due to reasons such as waterproofing. Using the optical fiber lamp of the present invention can completely solve the maintenance problem because the glass optical fiber has an extremely long lifespan and is not easily damaged. The laser diodes are uniformly placed in the control room, and it is extremely convenient to repair, debug, and replace them. The present invention is not only applied to airports but also can be applied to various ground lamps, underwater lamps, ice lamps, etc. There are no problems such as maintenance, water leakage, and electric leakage.

[0056] As described above, a three-proof fiber optic lamp provided by the present invention can be used as a display lamp on a glass curtain wall. By using red, green, and blue laser diodes, full-color light is combined and arranged on the glass curtain wall through invisible glass optical fibers. The light-emitting end can display patterns, words, pictures, and even play videos.

[0057] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should be regarded as within the protection scope of the present invention.
