Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a lamp. Background Art

[0002] With the continuous advancement of lighting technology, lamps, as an important part of the lighting system, have become more diverse and innovative in design, and their functions and performance have been significantly improved. Among the many functions of lamps, the focusing function is particularly important, which directly affects the distribution and irradiation range of light, and thus affects the lighting effect and user experience.

[0003] The existing optical zoom structure of lamps generally adopts the method of moving and zooming the light source set inside the lamp or the threaded mirror set on the lamp. However, the technical solution of moving and zooming the light source inside the lamp usually requires the heat dissipation structure corresponding to the light source to move synchronously, which will require a larger and more complex structure to assist the movement of the heat dissipation structure, resulting in the complexity of the overall structure of the lamp, making maintenance and disassembly difficult. The technical solution of moving and zooming the threaded mirror may cause obvious light blocking when the lamp emits light at a large angle during the lighting process. Utility Model Content

[0004] The utility model provides a lamp to solve the technical problems in the prior art that a complex lamp structure needs to be designed to realize a zoom function and that the use of a threaded mirror for zooming will cause large-angle light blocking when designing a waterproof structure. The utility model realizes the zooming of the lamp while simplifying the lamp design and avoiding the large-angle light blocking phenomenon generated during the lighting process of the lamp.

[0005] In order to solve the above technical problems, an embodiment of the utility model provides a lamp, including a light source, a light guide tube and a zoom tube; the light guide tube has a first light input end, and the first light input end covers the light source; the zoom tube is sleeved on the light guide tube, and the zoom tube has a first light output end away from the light source; a condenser is arranged on the zoom tube, and the condenser blocks the first light output end; wherein, along the length direction of the light guide tube, the zoom tube is movable relative to the light guide tube to change the distance between the light source and the condenser.

[0006] According to the lamp of the present application, the zoom barrel is mounted on the light guide barrel, and the zoom barrel is movable relative to the light guide barrel. The zoom barrel has a first light output end away from the light source, so that the focus of the light out of the light guide barrel can be changed by adjusting the zoom barrel, thereby flexibly adjusting the lighting range and brightness and improving the lighting quality. Furthermore, by moving the zoom barrel to change the focal length, the lamp can be adjusted without the need to design a complex structure to move the light source together during the focusing process, simplifying the design of the lamp and solving the problem of large-angle light blocking caused by using a threaded mirror for focusing in the prior art.

[0007] In some embodiments of the present application, the light guide tube has a first light guide channel, and along the length direction of the light guide tube, an end of the first light guide channel close to the light source is configured as a first light inlet end.

[0008] In this way, the first light guiding channel is arranged on the light guiding tube, so that the light emitted by the light source can be evenly dispersed, avoiding the problems of glare and uneven light. The end of the first light guiding channel close to the light source is designed as the first light input end, which can improve the light collection efficiency, optimize the light quality and reduce the attenuation of light during the transmission process.

[0009] In some embodiments of the present application, the cross-sectional area of ​​the first light guiding channel gradually increases along the length direction of the light guiding tube and in the direction away from the light source.

[0010] In this way, the cross-sectional area of ​​the first light guide channel will gradually increase along the length direction of the light guide tube and in the direction away from the light source, so that after the light emitted by the light source passes through the light guide tube, the irradiation range of the light target area can be expanded and the angle between the light and the central axis of the light guide tube can be increased.

[0011] In some embodiments of the present application, the inner wall of the first light guiding channel is provided with a reflective mirror surface.

[0012] In this way, a reflective mirror is provided on the inner wall of the first light guiding channel, which can improve the reflectivity of the light, ensure that the energy loss of the light is reduced when it is transmitted in the light guiding channel, significantly reduce the attenuation of the light during the transmission process, and improve the utilization rate of the light. The reflective mirror can also ensure that the light is transmitted along a predetermined path, avoid scattering or deviation from the predetermined path during the transmission process, help maintain the directionality and concentration of the light, so that the light can be more accurately irradiated to the target area, and the brightness and lighting range of the light are increased through multiple reflections and enhancements of the light in the first light guiding channel. This enhancement effect can make the lighting more uniform and bright, and improve the lighting quality.

[0013] In some embodiments of the present application, the zoom tube is sleeved on the outer circumference of the light guide tube.

[0014] By placing the zoom tube on the outer circumference of the light guide tube, all the light from the zoom tube can enter the light guide tube, thereby enhancing the brightness of the light and improving the lighting quality. Placing the zoom tube on the outer circumference of the light guide tube is also beneficial for the user to adjust the length of the zoom tube, and then adjust the zoom distance to achieve the effect of light zoom.

[0015] In some embodiments of the present application, the zoom barrel has a second light guiding channel extending along the length direction of the zoom barrel, and an end of the second light guiding channel away from the light source is configured as a first light emitting end.

[0016] In this way, by constructing the end of the second light guiding channel away from the light source as the first light output end, the distance of the zoom barrel can be fully utilized, the range of the focusing distance can be increased, and better zooming of the light can be achieved.

[0017] In some embodiments of the present application, a reflective mirror surface is disposed on the inner wall of the second light guiding channel.

[0018] In this way, a reflective mirror is provided on the inner wall of the second light guiding channel, which can improve the reflectivity of the light, ensure that the energy loss of the light is reduced when it is transmitted in the light guiding channel, significantly reduce the attenuation of the light during the transmission process, and improve the utilization rate of the light. The reflective mirror can also ensure that the light is transmitted along a predetermined path, avoid scattering or deviation from the predetermined path during the transmission process, help maintain the directionality and concentration of the light, so that the light can be more accurately irradiated to the target area, and the brightness and lighting range of the light are increased through multiple reflections and enhancements of the light in the second light guiding channel. This enhancement effect can make the lighting more uniform and bright, and improve the lighting quality.

[0019] In some embodiments of the present application, the zoom barrel includes a plurality of sub-zoom barrels nested with each other, and along the length direction of the light guide barrel, any sub-zoom barrel is movable relative to the light guide barrel.

[0020] In this way, a plurality of sub-zoom barrels nested in each other are arranged on the zoom barrel, and in the length direction of the light guide barrel, any sub-zoom barrel is movable relative to the light guide barrel, which can fully realize the adjustment of the distance from the light source to the condenser, thereby realizing the zoom function of the zoom barrel, and then changing the focal length, thereby determining the degree of light convergence. When the zoom barrel moves shorter, the focal length becomes shorter, the degree of light convergence increases, and the light density at the focus increases. When the condenser is away from the light source, the focal length becomes longer, the degree of light convergence weakens, and the light density at the focus becomes smaller.

[0021] In some embodiments of the present application, the sub-zoom barrel has a second sub-light guiding channel extending along the length direction of the sub-zoom barrel, and the cross-sectional area of ​​the second sub-light guiding channel remains unchanged along the length direction of the sub-zoom barrel.

[0022] In this way, a second sub-light guiding channel is provided on the sub-zoom barrel, extending along the length direction of the sub-zoom barrel. Along the length direction of the sub-zoom barrel, the cross-sectional area of ​​the second sub-light guiding channel remains unchanged, so that the angle of the light does not change when the zoom barrel is moved, which is equivalent to extending the light to achieve the zoom function.

[0023] In some embodiments of the present application, any sub-zoom tube is arranged on the outside of the light guide tube. Along the first direction, the length of the sub-zoom tube close to the light guide tube is greater than the length of the sub-zoom tube away from the light guide tube. The first direction is perpendicular and away from the center line of the light guide tube.

[0024] In this way, the sub-zoom tube is arranged on the outside of the light guide tube, which is beneficial to adjusting the distance of the zoom tube by movement, thereby changing the focal length of the zoom tube and improving shooting efficiency. The direction perpendicular to and away from the center line of the light guide tube is defined as the first direction. The advantage of making the length of the sub-zoom tube close to the light guide tube greater than the length of the sub-zoom tube away from the light guide tube is that the maneuverability of the mobile zoom tube can be improved, which is beneficial for the operator to realize the zoom function.

[0043] The existing optical zoom structure of lamps generally adopts the method of moving and zooming the light source set inside the lamp or the threaded mirror set on the lamp. However, the technical solution of moving and zooming the light source inside the lamp usually requires the heat dissipation structure corresponding to the light source to move synchronously, which will require a larger and more complex structure to assist the movement of the heat dissipation structure, resulting in the complexity of the overall structure of the lamp, making maintenance and disassembly difficult. The technical solution of moving and zooming with a threaded mirror, in order to achieve focal length adjustment, usually sets a threaded structure on the lens or lens barrel. On the one hand, these threaded structures may block part of the light. On the other hand, in order to ensure the waterproof performance of the lamp, it is necessary to seal the threaded connection or the interface between the lens and the lens barrel. These sealing measures may cause obvious light blocking when the lamp emits light at a large angle during the lighting process.

[0044] The embodiment of the utility model provides a lamp, which solves the technical problems in the prior art that a complex lamp structure needs to be designed to realize a zoom function and that the use of a threaded mirror for zooming will cause large-angle light blocking when designing a waterproof structure. The lamp can be zoomed while simplifying the lamp design and avoiding the large-angle light blocking phenomenon generated during the lighting process of the lamp.

[0045] The technical solution in the embodiment of the utility model is to solve the technical problems that the above-mentioned prior art needs to design a complex lamp structure to realize the zoom function and the use of a threaded mirror for zooming will cause large-angle light blocking when designing a waterproof structure. The overall idea is as follows:

[0046] The first light input end cover of the light guide tube of the lamp is arranged on the light source so that the light passing through the light guide tube is more concentrated and brighter. The zoom tube is sleeved on the light guide tube and the condenser is used to block the first light end of the zoom tube away from the light source, so that all the light passing through the first light output end can be adjusted by the condenser. Along the length direction of the light guide tube, the zoom tube can be moved relative to the light guide tube, thereby changing the distance between the light source and the condenser, thereby realizing the zoom function.

[0047] In order to better understand the above technical solution, the above technical solution will be described in more detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] Please also read Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the lamp 1 provided in the embodiment of the utility model when emitting light at a small angle; Figure 2 It is a schematic diagram of the structure of the lamp 1 provided in the embodiment of the utility model when emitting medium-angle light; Figure 3 It is a structural schematic diagram of the lamp 1 provided in this embodiment of the utility model when emitting light at a large angle.

[0049] In this embodiment, the lamp 1 includes a light source 11 , a light guide tube 12 , a zoom tube 13 , and a condenser lens 14 .

[0050] The light guide tube 12 has a first light inlet end 12a, and the first light inlet end 12a is covered on the light source 11. When the lamp 1 is working, the light source 11 emits light, which enters the light guide tube 12 through the first light inlet end 12a. In this way, the first light inlet end 12a of the light guide tube 12 of the lamp 1 is covered on the light source 11, so that the light guide tube 12 has a strong focusing effect, and can concentrate the light emitted by the light source 11 in a smaller area, so that the light passing through the light guide tube 12 is more concentrated and bright. Such a focusing effect is particularly important in lighting scenes that need to highlight a certain object or area. In addition, the first light inlet end 12a is covered on the light source 11, and the direction and range of the light can be controlled according to the shape and angle of the light guide tube 12, so that the light can be irradiated to a specific area as needed to avoid unnecessary interference to other areas.

[0051] The zoom barrel 13 is sleeved on the light guide barrel 12, and the zoom barrel 13 has a first light emitting end 13a away from the light source 11. The condenser 14 is arranged on the zoom barrel 13, and the condenser 14 blocks the first light emitting end 13a of the zoom barrel 13. Along the length direction of the light guide barrel 12, the zoom barrel 13 is movable relative to the light guide barrel 12 to change the distance between the light source 11 and the condenser 14. The light emitted by the light source 11 enters the light guide tube 12 through the first light inlet end 12a of the light guide tube 12, and then enters the zoom tube 13 from the light guide tube 12. The zoom tube 13 is movable relative to the light guide tube 12, so that the distance traveled by the light in the zoom tube 13 can be lengthened or shortened. When the zoom tube 13 moves to shorten the distance of the zoom tube 13, the distance traveled by the light in the zoom tube 13 is shortened, that is, the distance between the light source 11 and the condenser 14 is shortened, thereby shortening the focal length of the lamp 1. By shortening the focal length of the lamp 1, the focusing function is realized. When the zoom tube 13 moves to lengthen the distance of the zoom tube 13, The distance traveled by the light in the zoom barrel 13 becomes longer, that is, the distance between the light source 11 and the condenser 14 becomes longer, thereby lengthening the focal length of the lamp 1. By lengthening the focal length of the lamp 1, the focusing function is achieved, and the condenser 14 is set on the zoom barrel 13, and the first light output end 13a is blocked by the condenser 14, so that all light passing through the first light output end 13a can be adjusted by the condenser 14. In this way, there is no need to move the light source 11 or the distance of the threaded mirror 15, and a simple internal structure can be used to focus the lamp 1, and when designing a waterproof structure, large-angle light blocking will not occur.

[0052] In some embodiments, the light source 11 may be a colored light source 11, which can emit non-white light, and its spectrum range is mainly a monochromatic pure color wave spectrum range. LED is a common form of colored light source 11, which has a narrow spectrum, good monochromaticity, and has the characteristics of high light efficiency, high energy saving, multiple light colors, high safety, long life, fast response and low operating cost. The arrangement of colored light source 11 on the lamp 1 is conducive to the application of the lamp 1 in multiple fields. For example, in the process of stage lighting, it provides rich color changes for stage performances. The colored light source 11 is also widely used in multiple fields such as landscape lighting, traffic lights and automotive lighting.

[0053] In some embodiments, the light guide tube 12 can be a light mixing component. The light source 11 enters the interior of the light mixing component through the first light inlet end 12a. The light mixing component controls the light input and light output of the light sources 11 of different colors to achieve switching and color mixing of the light sources 11 of different colors. By setting the light guide tube 12 as a light mixing component, a variety of color lights can be mixed to create a richer lighting effect. For example, in the field of display and projection, the light mixing component can be used to achieve a more realistic and delicate color performance.

[0054] In some embodiments, the lens of the condenser 14 may be composed of two lenses, and the two lenses have strong light-gathering ability. An achromatic condenser 14 may also be used as the condenser 14 in this embodiment. The achromatic condenser 14 is composed of a series of lenses, and has a high degree of correction for chromatic aberration and spherical aberration, and can obtain an ideal image. It is a condenser 14 of the highest quality in bright field microscopy, and its NA value can reach 1.4.

[0055] In some embodiments, the condenser 14 disposed on the zoom barrel 13 is detachable, for example, a screw connection is adopted, and the condenser 14 and the zoom barrel 13 are fixed together by fasteners such as screws and nuts. The detachable design allows the user to quickly replace or adjust the combination of the condenser 14 and the zoom barrel 13 according to actual needs. Under different shooting or lighting requirements, the user can choose the most suitable combination of the condenser 14 and the zoom barrel 13 to obtain the best shooting or lighting effect. If the condenser 14 or the zoom barrel 13 fails or is damaged, the user can easily disassemble and replace the new parts without replacing the entire system, which not only reduces the maintenance cost, but also improves the maintainability and service life of the equipment. The detachable design makes the condenser 14 and the zoom barrel 13 more extensible. The user can add or remove different condensers 14 and zoom barrels 13 as needed to meet different shooting or lighting requirements. For example, when a stronger focusing effect is required, a high-magnification condenser 14 can be added. Compared with the design of integrally connecting the condenser 14 and the zoom tube 13, the detachable connection design allows the user to purchase and replace the condenser 14 or the zoom tube 13 separately without purchasing the entire system, which not only reduces the initial purchase cost but also makes subsequent upgrades and maintenance more economical.

[0056] In other embodiments, the condenser 14 on the zoom barrel 13 may also be designed to be integrally connected to the zoom barrel 13. The design of integrally connecting the condenser 14 on the zoom barrel 13 with the zoom barrel 13 can reduce the gap between components, making the entire device structure more compact and improving the stability of the device. This design reduces the risk of performance degradation or failure due to loose or misaligned components. The design of integrally connecting the condenser 14 on the zoom barrel 13 with the zoom barrel 13 optimizes the optical performance between the condenser 14 and the zoom barrel 13, reduces light loss or refraction effects caused by the connection, which helps to maintain the integrity of the light beam and improve the clarity and quality of the image. The design of integrally connecting the condenser 14 on the zoom barrel 13 with the zoom barrel 13 simplifies the operation of the device, and the user does not need to worry about the disassembly and installation of components, which makes the use of the device more convenient and quick, and improves work efficiency. The condenser lens 14 on the zoom barrel 13 is integrally connected to the zoom barrel 13 and generally uses high-quality materials and manufacturing processes, which improves the durability and reliability of the equipment. This design enables the equipment to withstand more severe environmental conditions and usage pressures, extending the service life of the equipment.

[0057] In some embodiments, a shell 16 is provided on the lamp 1, and a light source 11, a light guide tube 12 and a threaded mirror 15 are fixed on the shell, wherein the light source 11 is fixed at one end of the shell 16, and the threaded mirror 15 is fixed at the other end of the shell 16 away from the light source 11 along the length direction of the shell 16.

[0058] In the prior art, a relative spacing of a group of lenses provided on the lens is usually adjusted through a group of threaded pairs provided on the lens to achieve the purpose of zooming. In this process, on the one hand, since the threaded mirror needs to be moved by a threaded mechanism, the length of the threaded mechanism needs to be increased to ensure that the threaded mirror has sufficient movement, and a longer threaded mechanism may cause part of the light to be blocked. On the other hand, if the lamp needs to be designed to be waterproof, it is inevitable to seal the threaded connection or the interface between the lens and the lens barrel, such as using O-rings and silicone rubber to seal it, which will also increase the risk of light blocking. Therefore, using a threaded mirror to move and zoom may cause obvious light blocking at a large angle.

[0059] In the embodiment of the present application, the condenser 14 is movable relative to the housing 16, and the focal length is adjusted by changing the distance between the condenser 14 and the light source 11, while the threaded mirror 15 is fixedly connected to the housing 16. In this way, there is no need to move the threaded mirror 15, and the threaded pair only serves as a fixed connection. Therefore, the length of the threaded pair can be shorter. When making a waterproof design, there will be no light blocking phenomenon when the light is emitted at a large angle due to the waterproof structure or the threaded pair.

[0060] In some embodiments, the material of the thread mirror 15 can be glass, resin, polycarbonate and other materials to ensure the good light transmission performance of the thread mirror 15. Different materials of the thread mirror 15 can be selected for different scenes. For example, for scenes that require high light transmission and lightness, resin and polycarbonate are better choices, while for scenes that require high hardness and chemical stability, glass is more suitable. In other embodiments, the thread mirror 15 can also be connected to the shell in other detachable connection methods, and can be fixedly connected to the shell. The utility model does not limit the connection method of the thread mirror 15 and the shell 16, nor does it limit the type of thread mirror material.

[0061] Please also read Figures 1 to 3 In this embodiment, the light guide tube 12 has a first light guide channel 12b. Along the length direction of the light guide tube 12, one end of the first light guide channel 12b close to the light source 11 is configured as a first light inlet end 12a. When the lamp 1 is in use, the light emitted by the light source 11 enters the first light guide channel 12b of the light guide tube 12 through the first light inlet end 12a, and continues to irradiate along the length direction of the light guide tube 12. Thus, by providing the first light guide channel 12b on the light guide tube 12, the light emitted by the light source 11 can be evenly dispersed, thereby avoiding the problems of glare and uneven light. By configuring one end of the first light guide channel 12b close to the light source 11 as the first light inlet end 12a, the light collection efficiency can be improved, the light quality can be optimized, and the attenuation of light during transmission can be reduced.

[0062] Please also read Figures 1 to 3In the present embodiment, the cross-sectional area of ​​the first light guide channel 12b gradually increases along the length direction of the light guide tube 12 and in the direction away from the light source 11, so that the cross-sectional area at the end close to the light source 11 (also the first light inlet end 12a) is smaller than the cross-sectional area when the light comes out of the first light guide channel 12b, which can increase the angle between the light and the axis of the first light guide channel 12b when the light comes out of the first light guide channel 12b, thereby providing a wider lighting range for the lamp 1.

[0063] The cross-sectional area of ​​the first light guide channel 12b gradually increases, which can also enhance the stability and ease of use of the lamp 1. The special shape makes it have good stability, whether in storage or transportation. In addition, when the cross-sectional area of ​​the first light guide channel 12b is gradually increased, and the outer diameter of the light guide tube 12 also has the same change trend, the lamp 1 can be easily stacked and space can be saved, which is an important advantage for material management. The cross-sectional area of ​​the first light guide channel 12b gradually increases, so that the lamp 1 has a unique appearance and structure. The uniqueness increases the aesthetics of the lamp 1, and can also bring a significant three-dimensional effect to the lamp 1, which can give people a strong sense of space. It should be noted that such a design is more conducive to the human body holding the lamp 1. The user can control the entire lamp 1 by holding the smaller cross-sectional part of the lamp 1. In some embodiments, along the length direction of the light guide tube 12 and in the direction away from the light source 11, the cross-sectional area of ​​the first light guide channel 12b can also be designed to be unchanged or gradually reduced.

[0064] Please also read Figures 1 to 3 In this embodiment, a reflective mirror is provided on the inner wall of the first light guide channel 12b. After the light source 11 enters the first light guide channel 12b through the first light inlet end 12a, the light emitted by the light source 11 is totally reflected on the inner wall of the first light guide tube 12 channel, which can improve the reflectivity of the light, ensure that the energy loss is reduced when the light is transmitted in the light guide channel, significantly reduce the attenuation of the light during the transmission process, and improve the utilization rate of the light. The reflective mirror can also ensure that the light is transmitted along a predetermined path, avoid scattering or deviation from the predetermined path during the transmission process, help maintain the directionality and aggregation of the light, so that the light can be more accurately irradiated to the target area, and through multiple reflections and enhancements of the light in the first light guide channel 12b, the brightness and lighting range of the light are increased. This enhancement effect can make the lighting more uniform and bright, and improve the lighting quality.

[0065] Please also read Figures 1 to 3In this embodiment, the zoom barrel 13 is sleeved on the outer circumference of the light guide barrel 12. Sleeving the zoom barrel 13 on the outer circumference of the light guide barrel 12 can make the lamp 1 fully utilize the light emitted by the light source 11 of the zoom barrel 13, thereby reducing unnecessary power consumption. For places where the lamp 1 is used for a long time to take photos, a large amount of power can be saved. Sleeving the zoom barrel 13 on the outer circumference of the light guide barrel 12 can also facilitate the user to adjust the length of the zoom barrel 13, and then adjust the degree of light focus, so as to achieve precise control of the light and improve the flexibility of lighting. Whether it is close-range lighting that requires a strong focusing effect or long-range lighting that requires a wide range of floodlighting effects, the zoom barrel 13 can meet the needs. In some embodiments, the zoom barrel 13 can also be sleeved on the inner circumference of the light guide barrel 12. In some embodiments, in some embodiments, in the vertical direction along the length direction of the light guide barrel 12, the size of the zoom barrel 13 can be 1-2 mm larger than the size of the light guide barrel 12.

[0066] Please also read Figures 1 to 3 In this embodiment, the zoom barrel 13 has a second light guide channel 13b extending along the length direction of the zoom barrel 13, and the end of the second light guide channel 13b away from the light source 11 is configured as a first light outlet end 13a. After passing through the first light guide channel 12b, the light exits the light guide barrel 12 and enters the second light guide channel 13b of the zoom barrel 13, and then exits the second light guide channel 13b through the first light outlet end 13a of the zoom barrel 13 away from the light source 11. In this way, the length of the zoom barrel 13 itself can be fully utilized, thereby achieving the change of the distance between the light source 11 and the condenser 14, thereby achieving the change of the focal length and realizing the focusing function.

[0067] Please also read Figures 1 to 3 In this embodiment, a reflective mirror is provided on the inner wall of the second light guiding channel 13b. After the light enters the second light guiding channel 13b, the light will be totally reflected on the inner wall of the second light guiding channel 13b, which can improve the reflectivity of the light, ensure that the energy loss is reduced when the light is transmitted in the light guiding channel, significantly reduce the attenuation of the light during the transmission process, and improve the utilization rate of the light. The reflective mirror can also ensure that the light is transmitted along a predetermined path, avoid scattering or deviation from the predetermined path during the transmission process, help to maintain the directionality and aggregation of the light, so that the light can be more accurately irradiated to the target area, and the light is reflected and enhanced multiple times in the second light guiding channel 13b, thereby increasing the brightness and illumination range of the light. This enhancement effect can make the lighting more uniform and bright, and improve the lighting quality.

[0068] Please also read Figures 1 to 3In the present embodiment, the zoom barrel 13 includes a plurality of sub-zoom barrels 131 which are nested with each other. Along the length direction of the light guide barrel 12, any sub-zoom barrel 131 is movable relative to the light guide barrel 12. In this way, the zoom barrel 13 includes a plurality of sub-zoom barrels 131 which are nested with each other. On the one hand, due to the existence of the sub-zoom barrel 131, the sub-zoom barrel 131 can utilize the length of its own barrel body to change the distance between the light source 11 and the condenser 14, thereby increasing the adjustable range of the distance between the light source 11 and the condenser 14, and then changing the focal length, thereby determining the focusing function of the light.

[0069] In some embodiments, in two adjacent sub-zoom tubes 131, along the direction perpendicular to the length direction of the light guide tube 12, the maximum longitudinal length of the cross-section of the sub-zoom tube 131 that is farther from the axis of the light guide tube 12 is 1-2 mm larger than the maximum longitudinal length of the cross-section of the sub-zoom tube 131 that is closer to the axis of the light guide tube 12.

[0070] In some embodiments, in two adjacent sub-zoom tubes 131 , along the direction perpendicular to the length direction of the light guide tube 12 , the length of the sub-zoom tube 131 farther from the axis of the light guide tube 12 is 10-20 mm shorter than the length of the sub-zoom tube 131 closer to the axis of the light guide tube 12 .

[0071] For further information, see Figure 1 In the present embodiment, the second light guiding channel 13b of the zoom tube 13 and the first light guiding channel 12b of the light guiding tube 12 completely overlap, and the second sub-light guiding channel 131a of the sub-zoom tube 131 and the second light guiding channel 13b of the zoom tube 13 completely overlap. At this time, the distance between the condenser 14 and the light source 11 on the lamp 1 is the smallest, which will form a smallest and brightest light spot. At this time, the angle of the light path of the lamp 1 is the smallest.

[0072] For further information, see Figure 2 In the present embodiment, the second light guiding channel 13b of the zoom tube 13 and the first light guiding channel 12b of the light guiding tube 12 do not overlap, and the second sub-light guiding channel 131a of the sub-zoom tube 131 and the second light guiding channel 13b of the zoom tube 13 completely overlap. At this time, the distance between the condenser 14 and the light source 11 on the lamp 1 is medium, which will form a light spot of medium size and medium brightness. At this time, the angle of the light path of the lamp 1 is moderate.

[0073] For further information, see Figure 3In the present embodiment, the second light guiding channel 13b of the zoom barrel 13 and the first light guiding channel 12b of the light guiding barrel 12 do not overlap or only overlap by a small part (the length of the overlapping area is the smallest), the second sub-light guiding channel 131a of the sub-zoom barrel 131 and the second light guiding channel 13b of the zoom barrel 13 do not overlap or only overlap by a small part (the length of the overlapping area is the smallest), at this time, the distance between the condenser 14 on the lamp 1 and the light source 11 is the largest, and at this time, the angle of the light path of the lamp 1 is the largest.

[0074] Please also read Figures 1 to 3 In this embodiment, the sub-zoom barrel 131 has a second sub-light guide channel 131a extending along the length direction of the sub-zoom barrel 131, and the cross-sectional area of ​​the second sub-light guide channel 131a remains unchanged along the length direction of the sub-zoom barrel 131. In this way, the sub-zoom barrel 131 is provided with a second sub-light guide channel 131a extending along the length direction of the sub-zoom barrel 131, and the cross-sectional area of ​​the second sub-light guide channel 131a remains unchanged along the length direction of the sub-zoom barrel 131, so that when the zoom barrel 13 is moved, the angle of the light does not change, which is equivalent to extending the light to achieve the zoom function.

[0075] Please also read Figures 1 to 3 In this embodiment, any sub-zoom barrel 131 is arranged outside the light guide barrel 12, and along the first direction, the length of the sub-zoom barrel 131 close to the light guide barrel 12 is greater than the length of the sub-zoom barrel 131 away from the light guide barrel 12, and the first direction is perpendicular to and away from the center line of the light guide barrel 12. In this way, the sub-zoom barrel 131 is sleeved on the outside of the light guide barrel 12, which is conducive to adjusting the distance of the zoom barrel 13 by moving, thereby changing the focal length of the zoom barrel 13 and improving the shooting efficiency. The advantage of making the length of the sub-zoom barrel 131 close to the light guide barrel 12 greater than the length of the sub-zoom barrel 131 away from the light guide barrel 12 in the direction perpendicular to and away from the center line of the light guide barrel 12 as the first direction is that the mobility of the mobile zoom barrel 13 can be improved, which is conducive to the operator to realize the zoom function.

[0076] Please also read Figure 4 and Figure 5 , Figure 4 This is a schematic structural diagram of a cross section of a lamp 1 provided in an embodiment of the utility model; Figure 5 It is a schematic structural diagram of a cross section of another lamp 1 provided by an embodiment of the utility model. In the embodiment of the utility model, the cross section of the first light guide channel 12b is a polygon.

[0077] Furthermore, the cross-section of the first light guiding channel 12b can be set to a regular quadrilateral or a regular hexagon. By setting the cross-section of the first light guiding channel 12b to a regular quadrilateral or a regular hexagon, the transmission path of light in the first light guiding channel 12b can be more stable, and the refraction loss is also smaller, thereby improving the transmission reliability and efficiency of the optical signal. In some embodiments, the cross-section of the first light guiding channel 12b can be set to a circle. By setting the cross-section of the first light guiding channel 12b to a circle, due to the advantages of its shape and structure, it exhibits better durability when subjected to external pressure or impact, and the circular design of the first light guiding channel 12b helps to achieve uniform distribution of light and reduce shadow or glare problems caused by uneven light distribution.

[0078] In the embodiment of the utility model, the cross section of the second light guiding channel 13b is a polygon. Furthermore, the cross section of the second light guiding channel 13b can be set to a regular quadrilateral or a regular hexagon. By setting the cross section of the second light guiding channel 13b to a regular quadrilateral or a regular hexagon, the transmission path of light in the second light guiding channel 13b can be more stable, and the refraction loss is also smaller, thereby improving the transmission reliability and efficiency of the optical signal.

[0079] In the embodiment of the utility model, the cross section of the shell 16 can be set to be a polygon, and the shape of the cross section of the shell 16 can be adapted to the shape of the cross section of the light guide tube 12 and the shape of the cross section of the zoom tube 13 .

[0080] For example, the cross-section of the shell 16 can be a regular quadrilateral or a regular hexagon. Setting the shell 16 to a regular quadrilateral can reduce the difficulty of the assembly process of the lamp 1, thereby reducing the manufacturing cost. Moreover, the regular quadrilateral can fill the space well in a two-dimensional plane. For the lamp 1, the volume of the lamp 1 can be reduced as much as possible.

[0081] Setting the shell 16 to a regular hexagon can maximize the balance of the internal force of the lamp 1, thereby reducing the distortion and deformation of the structure. The inherent geometric properties and symmetry of the regular hexagon make the lamp have the same strength and stability in different directions. Moreover, each corner of the regular hexagon is supported by three adjacent sides, so the pressure balance is optimized, ensuring the solidity of the texture.

[0082] In some embodiments, the cross-section of the shell 16 can also be set to a circle. On the one hand, due to the special properties of the circular shape itself, first, under the same circumference, the circle has the largest area, which means that with a given amount of material, the circular shell can surround or cover a larger space, thereby improving the utilization efficiency of the material. On the other hand, because the circular cross-section has simple and smooth lines, the shell 16 is visually more beautiful and harmonious.

[0083] By arranging the light source 11, the light guide tube 12, the zoom tube 13 and the condenser 14 on the lamp 1, the first light input end 12a of the light guide tube 12 is covered on the light source 11, so that the light guide tube 12 has a strong focusing effect, and can concentrate the light emitted by the light source 11 in a smaller area, so that the light passing through the light guide tube 12 is more concentrated and bright. Such a focusing effect is particularly important in lighting scenes that need to highlight a certain object or area. In addition, by covering the first light input end 12a on the light source 11, the direction and range of the light can be controlled according to the shape and angle of the light guide tube 12, so that the light can be irradiated to a specific area as needed to avoid unnecessary interference to other areas.

[0084] The zoom tube 13 is mounted on the light guide tube 12 and has a first light output end 13a away from the light source 11. The zoom tube 13 can be adjusted to change the focus of the light output from the light guide tube 12, thereby flexibly adjusting the lighting range and brightness to improve the lighting quality.

[0085] The condenser 14 is arranged on the zoom barrel 13, and the condenser 14 is used to block the first light output end 13a, so that all the light passing through the first light output end 13a can be adjusted by the condenser 14. The zoom barrel 13 can be moved along the length direction of the light guide barrel 12, and thus changing the distance between the condenser 14 and the light source 11 is actually changing the focal length, thereby achieving a focusing effect. Furthermore, by moving the zoom barrel 13 to change the focal length, the light source 11 can be moved together during the focusing process of the lamp 1 without designing a complex structure. A first light guiding channel 12b is provided on the light guiding tube 12. Along the length direction of the light guiding tube 12, one end of the first light guiding channel 12b close to the light source 11 is constructed as a first light input end 12a. By providing the first light guiding channel 12b on the light guiding tube 12, the light emitted by the light source 11 can be evenly dispersed, thereby avoiding the problems of glare and uneven light. By designing one end of the first light guiding channel 12b close to the light source 11 as the first light input end 12a, the light collection efficiency can be improved, the light quality can be optimized, and the attenuation of light during the transmission process can be reduced.

[0086] Along the length direction of the light guide tube 12 and in the direction away from the light source 11, the cross-sectional area of ​​the first light guide channel 12b gradually increases, so that after the light source 11 emits light and passes through the light guide tube 12, the irradiation range of the target area of ​​the light can be expanded, and the angle between the light and the central axis of the light guide tube 12 can be increased.

[0087] A reflective mirror is provided on the inner wall of the first light guide channel 12b. The reflective mirror can improve the reflectivity of the light, ensure that the light reduces energy loss when it is transmitted in the light guide channel, significantly reduce the attenuation of the light during the transmission process, and improve the utilization rate of the light. The reflective mirror can also ensure that the light is transmitted along the predetermined path, avoid scattering or deviation from the predetermined path during the transmission process, and help maintain the directionality and aggregation of the light, so that the light can be more accurately irradiated to the target area. Through multiple reflections and enhancements of the light in the first light guide channel 12b, the brightness and lighting range of the light are increased. This enhancement effect can make the lighting more uniform and bright, and improve the lighting quality. The zoom barrel 13 is set on the outer peripheral surface of the light guide barrel 12, so that all the light from the zoom barrel 13 can enter the light guide barrel 12, thereby enhancing the brightness of the light and improving the lighting quality. The zoom barrel 13 is set on the outer peripheral surface of the light guide barrel 12, which is also conducive to the user to adjust the length of the zoom barrel 13, and then adjust the zoom distance to achieve the effect of light zoom.

[0088] The zoom barrel 13 has a second light guiding channel 13b extending along the length direction of the zoom barrel 13, and the end of the second light guiding channel 13b away from the light source 11 is constructed as a first light emitting end 13a. By constructing the end of the second light guiding channel 13b away from the light source 11 as the first light emitting end 13a, the distance of the zoom barrel 13 can be fully utilized, the range of the focusing distance can be increased, and the light can be better zoomed.

[0089] The inner wall of the second light guiding channel 13b is provided with a reflecting mirror. In this way, the reflecting mirror is provided on the inner wall of the second light guiding channel 13b, which can improve the reflectivity of the light, ensure that the energy loss of the light is reduced when it is transmitted in the light guiding channel, significantly reduce the attenuation of the light during the transmission process, and improve the utilization rate of the light. The reflecting mirror can also ensure that the light is transmitted along a predetermined path, avoid scattering or deviation from the predetermined path during the transmission process, help to maintain the directionality and concentration of the light, so that the light can be more accurately irradiated to the target area, and the brightness and lighting range of the light are increased through multiple reflections and enhancements of the light in the second light guiding channel 13b. This enhancement effect can make the lighting more uniform and bright, and improve the lighting quality.

[0090] The zoom barrel 13 includes a plurality of sub-zoom barrels 131 which are nested with each other. Along the length direction of the light guide barrel 12, any sub-zoom barrel 131 is movable relative to the light guide barrel 12. In this way, a plurality of sub-zoom barrels 131 which are nested with each other are arranged on the zoom barrel 13, and along the length direction of the light guide barrel 12, any sub-zoom barrel 131 is movable relative to the light guide barrel 12. This can fully realize the adjustment of the distance from the light source 11 to the focusing lens 14, thereby realizing the zoom function of the zoom barrel 13, and then changing the focal length, thereby determining the degree of light convergence. When the zoom barrel 13 moves shorter, the focal length becomes shorter, the degree of light convergence increases, and the light density at the focus increases. When the focusing lens 14 is away from the light source 11, the focal length becomes longer, the degree of light convergence weakens, and the light density at the focus decreases.

[0091] The sub-zoom barrel 131 has a second sub-light guiding channel 131a extending along the length direction of the sub-zoom barrel 131, and the cross-sectional area of ​​the second sub-light guiding channel 131a remains unchanged along the length direction of the sub-zoom barrel 131. In this way, the sub-zoom barrel 131 is provided with a second sub-light guiding channel 131a extending along the length direction of the sub-zoom barrel 131, and the cross-sectional area of ​​the second sub-light guiding channel 131a remains unchanged along the length direction of the sub-zoom barrel 131. This ensures that the angle of the light does not change when the zoom barrel 13 is moved, which is equivalent to extending the light to achieve a zoom function.

[0092] Any sub-zoom barrel 131 is arranged on the outside of the light guide barrel 12. Along the first direction, the length of the sub-zoom barrel 131 close to the light guide barrel 12 is greater than the length of the sub-zoom barrel 131 away from the light guide barrel 12. The first direction is perpendicular to and away from the center line of the light guide barrel 12. In this way, the sub-zoom barrel 131 is sleeved on the outside of the light guide barrel 12, which is beneficial to adjusting the distance of the zoom barrel 13 by movement, thereby changing the focal length of the zoom barrel 13 and improving the shooting efficiency. The direction perpendicular to and away from the center line of the light guide barrel 12 is the first direction. The advantage of making the length of the sub-zoom barrel 131 close to the light guide barrel 12 greater than the length of the sub-zoom barrel 131 away from the light guide barrel 12 is that the maneuverability of the mobile zoom barrel 13 can be improved, which is beneficial for the operator to realize the zoom function.
