Description

Technical Field

[0001] The utility model relates to the technical field of visual detection, in particular to an all-in-one heat-resistant light source. Background Art

[0002] Light sources are widely used in modern industry and daily life, playing an indispensable role in fields ranging from daily illumination to industrial testing, medical equipment, and even scientific research. However, in practical applications, traditional point light source technology has many limitations, especially the insufficient brightness of a single point light source and its lifespan under specific environmental conditions, which have become key factors restricting its performance.

[0003] Specifically, in some scenarios operating under high-temperature conditions, the service life of traditional point light sources will be significantly shortened. This is because prolonged exposure to extreme temperatures can cause the internal materials of the light source to age or even damage, seriously affecting the operation of the entire light source. Frequent light source replacement not only consumes manpower and material resources, but can also interrupt production processes and cause financial losses. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0031] Currently, traditional point light sources are difficult to provide sufficient light intensity when concentrated strong light is needed for delicate work or long-distance projection. Although the overall brightness can be improved by adding multiple point light sources, the service life of ordinary light sources will be greatly shortened for some scenes working under high temperature conditions. This is because the internal materials of the light source will age or even be damaged when exposed to extreme temperature environments for a long time, which seriously affects the operation of the entire light source. In addition, frequent replacement of light sources not only consumes manpower and material resources, but may also interrupt the production process and cause economic losses. In view of the above two major technical bottlenecks, this embodiment proposes an innovative solution: using a one-to-many fiber bundle structure to achieve effective light convergence.

[0032] Please refer to Figure 1-5As shown, this embodiment provides an all-in-one heat-resistant light source 100 , which includes: a light-emitting panel 110 , an optical fiber fixing seat 112 , an optical fiber 113 , a heat sink 115 , a reflector 114 , a fan fixing seat 116 , a fan 117 and a housing 118 .

[0033] Preferably, in this embodiment, eight lamp beads 111 are provided on one side of the light-emitting panel 110, and the optical fiber fixing seat 112 is provided with eight optical fiber interfaces 12a. The optical fiber fixing seat 112 is arranged opposite to the side of the light-emitting panel 110 provided with the lamp beads 111, so that any optical fiber interface 12a corresponds to a lamp bead 111, and each lamp bead 111 emits light to the corresponding optical fiber interface 12a; further, a plurality of optical fibers 113 are provided, and the first end of each optical fiber 113 is connected to an optical fiber interface 12a, and the second end, that is, the end away from the optical fiber interface 12a, is provided with a light outlet 12b for outputting the light of the lamp bead 111; the optical fiber 113 outputs the light of the lamp bead 111 outward through the light outlet 12b, and at least the parts of the light outlet 12b of the eight optical fibers 113 connected to different optical fiber interfaces 12a are arranged together.

[0034] Preferably, the light outlets 12b of at least two optical fibers 113 are collectively arranged.

[0035] According to the above solution, preferably, in this embodiment, the light outlets 12b of all the optical fibers 113 are collectively arranged.

[0036] According to the above scheme, it can be understood that this embodiment provides multiple lamp beads 111, and by using multiple optical fibers 113 with one end connected to different optical fiber interfaces 12a, and at least a portion of the light outlets 12b at the other end are collectively arranged, so that the weak light signals of multiple lamp beads 111 from different directions or positions can be effectively converged through the light outlets 12b of different optical fibers 113. This illumination method significantly improves the final illumination brightness of the light source as a whole. More importantly, due to the excellent heat resistance of optical fibers, they can operate stably for a long time in working environments as high as hundreds of degrees Celsius without being affected, thereby reducing the impact of the heat of the lamp beads 111 and the surrounding environment on the light, greatly extending the service life of the entire light source, and avoiding the loss caused by frequent replacement of light sources.

[0037] Preferably, the reflector 114 is arranged between the light-emitting panel 110 and the optical fiber fixing seat 112, and a reflective cup 121 is provided in the reflector 114, and the reflective cup 121 corresponds to the lamp bead 111 and the optical fiber interface 12a. The reflective cup 121 can be used to aggregate the light emitted by each lamp bead 111 at the corresponding optical fiber interface 12a, thereby increasing the intensity of the light entering the optical fiber 113 and further increasing the brightness of the light at different light outlets 12b.

[0038] Preferably, the side of the light emitting board 110 away from the lamp beads 111 is fitted on the heat sink 115 . This structure can transfer the heat generated by the light emitting board 110 during operation to the heat sink 115 in time, thereby reducing the heat of the light emitting board 110 .

[0039] Preferably, the reflective cup 121 includes a reflective cavity 13a and a first cup opening 13b and a second cup opening 13c provided on both sides of the reflective cavity 13a. The first cup opening 13b faces the lamp bead 111 and abuts against the light-emitting board 110. The second cup opening 13c faces the optical fiber interface 12a. The optical fiber interface 12a is connected to the reflective cavity 13a through the second cup opening 13c. It can be understood that the light from each lamp bead 111 is reflected in the reflective cavity 13a of the corresponding reflective cup 121 and passes through the first cup. The opening 13b abuts against the light-emitting board 110, so that the corresponding lamp bead 111 is covered in the reflective cavity 13a. This structure can prevent the light of the lamp bead 111 from leaking out from the gap between the reflective cup 121 and the light-emitting board 110, and connect the optical fiber interface 12a to the reflective cavity 13a through the second cup opening 13c, so that the light of the lamp bead 111 can be reflected in the reflective cavity 13a and then irradiated into the optical fiber 113 connected to the optical fiber interface 12a through the second cup opening 13c.

[0040] Preferably, the diameter of the first cup mouth 13b is larger than the diameter of the second cup mouth 13c. The purpose of this structure is to enhance the reflective effect of the light of the lamp bead 111. It can be understood that the structure is designed so that the side wall of the reflective cavity 13a forms an inclined slope toward the lamp bead 111, so that most of the light emitted from the lamp bead 111 will be irradiated on the side wall of the reflective cavity 13a, so that it can be fully reflected, thereby increasing the illumination intensity.

[0041] Preferably, a plurality of heat dissipation fins 141 are provided on the side of the heat sink 115 facing away from the light-emitting panel 110, and a first heat dissipation channel 14a is formed between any two adjacent heat dissipation fins 141; it can be understood that the purpose of the heat dissipation fins 141 is to increase the heat dissipation area and further dissipate heat for the heat dissipation fins 141 through the first heat dissipation channel 14a, thereby improving the heat dissipation speed.

[0042] Preferably, it also includes a fan fixing base 116 installed on the heat sink 115 and a fan 117 installed on the fan fixing base 116. The fan fixing base 116 is used to install a side of the fan 117 spaced apart from the heat sink 115 to form a second heat dissipation channel 14b, and the fan 117 is arranged toward the second heat dissipation channel 14b. It can be understood that the fan 117 is facing the second heat dissipation channel 14b, so that the wind generated by the fan 117 when working can accelerate the circulation of the airflow in the second heat dissipation channel 14b, thereby improving the heat dissipation speed of the heat sink 115 to the light-emitting panel 110.

[0043] Preferably, it also includes a shell 118 installed on the outside of the light-emitting panel 110. Furthermore, the shell in this embodiment is also arranged on the outside of the reflective plate 114, and the optical fiber fixing seat 112 is arranged on the top surface of the shell and covers the top surface of the shell. One side of the heat sink 115 is protruded outward from the inside of the shell 118. In this embodiment, the side of the heat sink 115 protruding from the shell 118 is the side of the shell 118 away from the optical fiber fixing seat 112, that is, the bottom surface of the shell. By protruding the heat sink 115, the two ends of the second heat dissipation channel 14b can be connected to the outside, thereby accelerating the circulation of airflow, and the heat sink 115 is fully exposed to the air, thereby improving the heat dissipation speed.

[0044] Preferably, the optical fiber 113 can be detachably installed in the optical fiber interface 12a. The advantage of designing this structure is that the optical fiber 113 installed in different optical fiber interfaces 12a can be disassembled to meet the needs of using different light intensities and improve the adaptability of the light source.

[0045] Preferably, the optical fiber 113 includes a core and a cladding wrapped around the core, and the cladding is made of a high-temperature resistant material. By using the high-temperature resistant material cladding of the optical fiber 113 to cover the core, the overall heat resistance of the optical fiber is improved, and the working stability of the light source in a high-temperature environment is improved. It can be understood that in this embodiment, the core is made of glass optical fiber, and the material of the high-temperature resistant material of the cladding can be polyimide (PI) as a high-temperature resistant material. Polyimide-coated optical fiber can be used at general high temperatures, has excellent thermal stability, and the temperature resistance range can reach below 300°C. In other embodiments, other high-temperature resistant optical fiber options can also be used.

[0046] In summary, the present invention provides an all-in-one heat-resistant light source. By providing multiple lamp beads and connecting one end of multiple optical fibers to different optical fiber interfaces, and by collectively providing at least a portion of the light outlets at the other end, the weak light signals from multiple lamp beads from different directions or positions can be effectively converged through the light outlets of different optical fibers. This illumination method significantly improves the overall final illumination brightness of the light source. More importantly, due to the excellent heat resistance of optical fibers, it can operate stably and unaffected in working environments of up to hundreds of degrees Celsius for a long time, thereby reducing the impact of the heat from the lamp beads and the surrounding environment on the light, greatly extending the service life of the entire light source, and avoiding the losses caused by frequent light source replacement.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
