Description

Technical Field

[0001] The present invention relates to the technical field of quartz optical fibers, and in particular to a quartz luminescent optical fiber and an end-point luminescent structure. Background Art

[0002] Cold light source quartz luminescent optical fiber is a high-efficiency lighting product made of quartz material and advanced optical technology. The luminescence principle of quartz luminescent optical fiber is based on the total reflection principle of light and the fluorescence effect. When the light signal enters the inside of the optical fiber, due to the special structure inside the optical fiber, the light is totally reflected multiple times inside the optical fiber, thereby achieving long-distance transmission. At the same time, the coating material of the optical fiber has a fluorescence effect. The endpoint light is realized by the optical fiber coating material, and the surface of the optical fiber bundle does not emit light. The light source has a high concentration and strong brightness.

[0003] LED lighting is the most mature solid lighting now. LED has attracted much attention for its high electro-optical conversion efficiency. However, the distance between the LED chip and the phosphor is very close, and the luminous efficiency of the phosphor is severely limited by the heat emitted by the LED chip. The heat dissipation problem has always been an important factor restricting the development of LED. In addition, LED technology mainly relies on the principle of electroluminescence, and the transmission distance is relatively short. It is easily disturbed by the external environment. Under certain special weather conditions, its visibility may be affected, thereby affecting the luminous effect. In addition, the luminous principle of laser-based white light sources is similar to that of LEDs, and because lasers can be transmitted using optical fibers, the phosphors and lasers can be separated from each other, thereby completely solving the problem of phosphors being affected by chip heat dissipation, but it is not convenient to achieve linear light sources.

[0004] In the prior art, both LED light sources and laser light sources have limited luminous effects due to their own characteristics; and during the heat dissipation process of the light source endpoint, dust in the air is easily attracted to the surface of the light source through the heat dissipation holes under the conditions of light and heat, causing the light source to be covered with dust, affecting the luminous effect.

[0005] To this end, the present invention provides a quartz light-emitting optical fiber and an end-point light-emitting structure. Summary of the invention

DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0034] See also Figure 1 - Figure 8 The present invention provides a quartz light-emitting optical fiber and an end-point light-emitting structure, comprising: an optical fiber bundle 1; a light source; the optical fiber bundle 1 comprises a cladding 11, a core layer 12, and a scatterer 13; the cladding 11 is coated on the outer surface of the core layer 12; the scatterer 13 is arranged on the inner surface of the core layer 12; the radius R1 of the core layer 12 is 25 to 40 μm, and its refractive index difference Δn1 is 0 to 0.3%; the radius R2 of the cladding 11 is 60 to 90 μm, and its refractive index difference Δn2 is -0.1% to -0.03%; the cladding 11 and the core layer 12 constitute a circular waveguide structure; the outermost structure of the cladding 11 is provided with a resin coating layer, the radius R3 of the resin coating layer is 120 to 150 nm, and its refractive index difference Δn3 is -3% to -6%, and the light source is arranged at one end of the optical fiber bundle 1.

[0035] When the quartz luminescent optical fiber provided by the present invention is used, the quartz luminescent optical fiber is composed of a cladding 11, a core layer 12, and a scatterer 13, wherein the cladding 11 is coated on the outer surface of the core layer 12, and the scatterer 13 is distributed on the inner surface of the core layer 12 with a certain density and depth, wherein the refractive index of the cladding 11 is greater than the refractive index of the core layer 12, and the scatterer 13 is composed of a material with a different refractive index from the core layer 12, and the cladding 11 and the core layer 12 form a circular waveguide structure; when the guided light propagates in the core layer 12, when it encounters the scatterer 13, a part of the light will leak out due to scattering; since the scatterer 13 has different depths or densities at different positions on the surface of the core layer 12, the guided light attenuation coefficients at different positions of the optical fiber are different, thereby ensuring that the scattered light intensity is evenly distributed on the optical fiber surface; in addition, by reasonably designing the depth or density of the scatterer 13, the reasonable utilization of light energy can be achieved, so that most of the guided light energy can be scattered out of the optical fiber by the scatterer 13 instead of leaking from the end of the optical fiber.

[0036] Furthermore, if Figure 3 and Figure 8 As shown, the core layer 12 is made of thermosetting resin; the cladding 11 is made of fluorinated ethylene propylene; the scatterer 13 is made of polymethyl methacrylate or other polymer materials; the light source is one of a halogen lamp, a xenon lamp, an LED lamp and a laser.

[0037] When the core layer 12 and cladding 11 provided by the present invention are used, the core layer 12 is usually made of thermosetting resin, which has excellent temperature resistance and is not easily deformed by heat; the cladding 11 can be made of fluorinated ethylene propylene; the scatterer 13 can be made of polymethyl methacrylate or other polymer materials, or fluorescent materials; the light source is diverse, and any one of halogen lamps, xenon lamps, LED lamps and lasers can be selected, so as to ensure that even if the optical fiber is long, strong side scattered light is emitted; during preparation, the core layer 12 of the optical fiber with uniform light emission is usually first produced, and then a groove is engraved on the surface of the core layer 12 according to the designed density and depth, and then the scatterer 13 material is filled in the groove, and finally the cladding 11 material is coated on the surface of the core layer 12.

[0038] Furthermore, if Figure 3 and Figure 6 As shown, a quartz light-emitting optical fiber endpoint light-emitting structure, the light source includes a shell 2, a light-emitting lamp body 25, two connecting blocks 24 are fixedly connected to the inner wall of the shell 2, a connector 23 is fixedly connected between the two connecting blocks 24, a core board 26 is fixedly connected to the connector 23, and the light-emitting lamp body 25 is installed on the side wall of the core board 26; the optical fiber harness 1 is on the other side wall of the core board 26, and one end of the optical fiber harness 1 is provided with a mounting structure; the mounting structure includes a connecting tube 41 which is sleeved on the outer wall of the optical fiber harness 1, one end of the connecting tube 41 is fixedly connected to a mounting head 42, and the mounting head 42 is threadedly connected to the outside of the connecting head 23.

[0039] When the installation structure provided by the present invention is in use, during the installation process of the optical fiber harness 1 and the light source, the handheld connecting tube 41 is inserted into the shell 2, and when the installation head 42 is close to the connecting head 23, it is rotated and threaded until the installation head 42 is tightly connected to the connecting head 23, and the optical fiber harness 1 is in close contact with the core board 26. At this time, the installation and fixation of the optical fiber harness 1 are realized, thereby completing the assembly of the optical fiber harness 1, the core board 26 and the light-emitting lamp body 25.

[0040] Furthermore, if Figure 3 As shown, a plurality of heat dissipation holes 28 are provided on the top of the shell 2 , a mounting base 5 is fixedly connected to the top inner wall of the shell 2 , a fan 51 is installed on the mounting base 5 , and the fan 51 is directly above the connector 23 .

[0041] When the heat dissipation holes 28 provided by the present invention are used, the heat inside the housing 2 can be quickly dissipated by providing the heat dissipation holes 28 ; and the heat inside the housing 2 can be heated and dissipated by providing the fan 51 .

[0042] Furthermore, if Figure 4 and Figure 5As shown, a dustproof plate 3 is provided on the top outer wall of the shell 2, and two cavities 37 are opened on the top of the shell 2, and the cavities 37 are respectively arranged on both sides of the dustproof plate 3, and a movable plate 31 is slidably connected in each of the cavities 37, and three plug posts 32 are fixedly connected on the side wall of the movable plate 3 close to the dustproof plate 3, and the plug posts 32 are all inserted on the dustproof plate 3; three limit posts 33 are fixedly connected on the side wall of the movable plate 31 away from the plug posts 32, and the limit posts 33 are all slidably connected in the cavity 37, and a spring 34 is sleeved on the outer side of the limit post 33, one end of the spring 34 is fixedly connected to the movable plate 31, and the other end is fixedly connected to the inner wall of the cavity 37; a push block 35 is fixedly connected to the top of the movable plate 31.

[0043] The dustproof plate 3 is used to block dust from entering the shell 2 through the heat dissipation holes 28, but dust will fall on the dustproof plate 3. After a period of time, the dustproof plate 3 will be blocked, resulting in poor heat dissipation effect, and the dustproof plate 3 needs to be disassembled; when the movable plate 31, the limiting column 33 and the plug column 32 provided by the present invention are in use, the pushing blocks 35 are pushed to both sides, and the pushing blocks 35 drive the movable plate 31 to move to both sides. The movable plate 31 drives the plug column 32 and the limiting column 33 to slide to both sides, and the spring 34 is compressed, and the plug column 32 leaves the dustproof plate 3, and the fixation of the dustproof plate 3 is released, and the fixed plate 3 can be removed; when installing the dustproof plate 3, it is also necessary to push the pushing blocks 35 to both sides, and then place the dustproof plate 3 steadily, release the pushing blocks 35, and under the action of the spring 34, push the movable plate 31 and the plug column 32 to slide inward, and the plug column 32 is inserted on the dustproof plate 3, so that the dustproof plate 3 can be fixedly installed, thereby realizing the function of quickly installing and removing the dustproof plate 3.

[0044] Furthermore, if Figure 7 As shown, a limiting pin 351 is provided on one side of the pushing block 35 close to the limiting column 33; both ends of the top of the shell 2 are fixedly connected with a fixing block 352, and the limiting pin 351 is respectively slidably connected in the fixing block 352; both ends of the top of the shell 2 are fixedly connected with a first fixing seat 353 and a second fixing seat 354, and the limiting pin 351 cooperates with the first fixing seat 353 and the second fixing seat 354 respectively.

[0045] Since the spring 34 will deform under external force, the pushing block 35 cannot be fixed by the spring 34 alone. When the limit pin 351 provided by the present invention is used, after installation, the pushing block 35 needs to be fixed. The limit pin 351 needs to be pushed to the first fixed seat 353, and then the limit pin 351 is rotated and inserted into the first fixed seat 353 to complete the fixation; when the dustproof plate 3 needs to be removed, the limit pin 351 needs to be moved to the second fixed seat 354 to release the fixation of the pushing block 35, and then the pushing block 35 can be moved.

[0046] Furthermore, if Figure 3 As shown, a plurality of fins 27 are fixedly connected to the two inner side walls of the shell 2, and the shell 2 is made of metal.

[0047] When the fins 27 provided by the present invention are used, the heat dissipation area is increased and the speed of heat dissipation is accelerated by setting the fins 27; and the metal material is used, and the metal material has a certain thermal conductivity, which facilitates the heat dissipation.

[0048] Furthermore, if Figure 6 As shown, a blocking block 4 is fixedly connected to the outer wall of the connecting pipe 41 . The blocking block 4 is configured to be conical and cooperates with the housing 2 .

[0049] When the blocking block 4 provided by the present invention is in use, during the installation process of the mounting head 42 and the connecting head 23 , the blocking block 4 cooperates with the housing 2 to seal the housing 2 .

[0050] Furthermore, if Figure 2 and Figure 3 As shown, a condenser 22 is fixedly connected to the side wall of the connector 23 , and the inner wall of the condenser 22 is coated with fluorescent powder; a transparent glass 21 is fixedly connected to the side wall of the housing 2 , and the transparent glass 21 cooperates with the condenser 22 .

[0051] When the condenser 22 provided by the present invention is in use, the condenser 22 is provided to improve the condensing effect and maintain the brightness of the light-emitting lamp body 25 .

[0052] Furthermore, if Figure 5 As shown, a side plate 36 is fixedly connected to the bottom end of the pushing block 35 , and the side plate 36 slides in the housing 2 .

[0053] When the side plate 36 provided by the present invention is in use, the push plate drives the side plate 36 to slide in the shell 2 during movement, and the side plate 36 limits the push plate in the horizontal direction. At the same time, the side plate 36 blocks the sliding opening together with the push plate to reduce the entry of external dust.

[0054] Working principle: Scatterers 13 are distributed on the inner surface of the core layer 12 with a certain density and depth. When the conducted light propagates in the core layer 12, when it encounters the scatterers 13, part of the light will leak out due to scattering. Since the scatterers 13 have different depths or densities at different positions on the surface of the core layer 12, the conducted light attenuation coefficients at different positions of the optical fiber are different, thereby ensuring that the scattered light intensity is evenly distributed on the optical fiber surface. Moreover, by reasonably designing the depth or density of the scatterers 13, it is also possible to reasonably utilize the light energy, so that most of the conducted light energy is scattered by the scatterers 13. The optical fiber bundle 1 is installed and fixed to the core board 26, thereby completing the assembly of the optical fiber bundle 1, the core board 26 and the light emitting lamp body 25. The dustproof plate 3 is used to block dust from entering the interior of the housing 2 through the heat dissipation holes 28, but dust will fall on the dustproof plate 3. After a period of time, the dustproof plate 3 will be blocked, resulting in poor heat dissipation effect. The dustproof plate 3 needs to be disassembled; when the movable plate 31, the limiting column 33 and the plugging column 32 provided by the present invention are in use, the pushing blocks 35 are pushed toward both sides, the pushing blocks 35 drive the movable plate 31 to move toward both sides, the movable plate 31 drives the plugging column 32 and the limiting column 33 to slide toward both sides, the springs 34 are compressed, the plugging column 32 leaves the dustproof plate 3, the fixation of the dustproof plate 3 is released, and the fixed plate can be removed; when installing the dustproof plate 3, it is also necessary to push the pushing blocks 35 toward both sides, then place the dustproof plate 3 steadily, release the pushing blocks 35, and under the action of the springs 34, the movable plate 31 and the plugging column 32 are pushed to slide inwards, The plug post 32 is inserted into the dustproof plate 3, so that the dustproof plate 3 can be fixed and installed, and the function of quick installation and removal of the dustproof plate 3 can be realized; because the spring 34 will deform under the external force, the push block 35 cannot achieve the fixing effect only by the spring 34. After the installation is completed, the push block 35 needs to be fixed, and the limit pin 351 needs to be pushed to the first fixed seat 353, and then the limit pin 351 is rotated and inserted into the first fixed seat 353 to complete the fixation; when the dustproof plate 3 needs to be removed, the limit pin 351 needs to be moved to the second fixed seat 354 to release the fixation of the push block 35, and then the push block 35 can be moved.

[0055] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
