[0010] In a possible implementation manner of the first aspect, the first light guide section and the second light guide section are connected through an arc-shaped connecting section.

[0011] In some embodiments, the diameter of the first light guide section gradually decreases in the direction of light propagation.

[0012] With reference to the first aspect, in a possible implementation manner, the rear side of the light-out hole is provided with a stepped ring groove, and an outer periphery of the second light guide section is provided with an axial limiting protrusion, the axial limiting protrusion is inserted into the stepped ring groove and can limit displacement of the second light guide section in an axial direction of the second light guide section.

[0013] In some embodiments, an outer periphery of the stepped ring groove is provided with at least one circumferential limiting groove, and an outer periphery of the axial limiting protrusion is provided with a circumferential limiting protrusion, the circumferential limiting protrusion is inserted into the circumferential limiting groove to limit displacement of the second light guide section in a circumferential direction of the second light guide section.

[0014] With reference to the first aspect, in a possible implementation manner, the mounting bracket comprises a connecting base plate and an overhanging base plate, the connecting base plate is located above the second light guide section and is attached to a rear side of the panel, and the overhanging base plate is arranged at an upper edge of the connecting base plate and extends rearward, the light-out assembly is attached to an upper plate surface of the overhanging base plate, and the overhanging base plate is provided with a displacement-avoiding gap corresponding to the indicating light source.

[0018] The reason why the existing indicator light causes the above-mentioned disassembly inconvenience is that the light source plate and the light guide column are distributed along the front-rear direction, and the assembly operation thereof with the panel requires a larger operation space, so that the panel needs to be in a state separated from the device main body, after the indicator light is installed on the panel, the cable in the device main body needs to be connected to the light source plate, and then the panel is assembled to the device main body again, and in the process, the cable connected with the light source plate needs to be prevented from being clamped between the panel and the shell of the device main body; when maintenance is needed, the light source plate needs to be disassembled for maintenance, and the panel also needs to be disassembled, the conductive connection between the light source plate and the device main body is disconnected, and then the maintenance is performed.

[0036] In the claims, the specification, and the drawings of the present application, terms such as "attached", "connected", "engaged", "coupled", "fixed", etc., if used, are to be construed as loose or fixed relationships depending on the context in which they are used and the ordinary meaning of such terms.

[0037] Please refer to Figure 1 and Figure 2 , the indicator lamp assembly provided by the utility model will be described. The indicator lamp assembly comprises a panel 1, a light guide column 2, a mounting bracket 3 and a light emitting assembly 4; the panel 1 is provided with a light emitting hole 5 extending through front and back; the light guide column 2 has a first light guide section 210 and a second light guide section 220, the first light guide section 210 extends in the up-down direction, the second light guide section 220 is connected to the lower end of the first light guide section 210 and extends forward, and the second light guide section 220 is inserted into the light emitting hole 5; the mounting bracket 3 is arranged above the second light guide section 220 and is fixed to the rear side of the panel 1; the light emitting assembly 4 is arranged above the first light guide section 210 and is fixed to the upper side of the mounting bracket 3, the indicator light source 420 on the light emitting assembly 4 is arranged opposite to the first light guide section 210, and the upper side of the light emitting assembly 4 is provided with a wiring port 430.

[0038] In the embodiment, the upper side wall plate of the device main body is generally not connected with the internal electrical devices, so that in the process of assembling the device main body, the upper side wall plate is often the last component to be assembled, and in the maintenance process, the upper side wall plate is often the first component to be removed. Since the internal devices of the device main body are closely arranged, it is difficult to adopt the operation of wiring in the direction perpendicular to the up-down direction, so the existing indicator lamp needs to be selected to be wired before the panel 1 is assembled.

[0039] In the embodiment, the outer circumferential side of the light guide column 2 is covered with a reflective layer to avoid wasting light and ensure light brightness.

[0040] In the embodiment, in order to adapt to the light emitting assembly 4 and meet the light guiding requirement, the included angle between the first light guiding section 210 and the second light guiding section 220 is 85°-95°, and the included angle of 90° is exemplarily shown in the figure.

[0041] In the embodiment, the wiring port 430 is a quick plug port, which can be plugged and unplugged with the end of the cable.

[0042] The reason why the existing indicator light causes the above-mentioned inconvenience in disassembly is that the light source plate 410 and the light guide column 2 are distributed along the front-rear direction, and the assembly operation thereof with the panel 1 requires a relatively large operation space, so the panel 1 needs to be in a state of being separated from the device main body. After the indicator light is installed on the panel 1, the cable in the device main body needs to be connected to the light source plate 410, and then the panel 1 is assembled to the device main body. In the process, the cable connected to the light source plate 410 also needs to be avoided from being clamped between the panel 1 and the shell of the device main body. When maintenance is needed, the light source plate 410 needs to be disassembled for maintenance, which also requires the panel 1 to be disassembled, the conductive connection between the light source plate 410 and the device main body to be disconnected, and then the maintenance is performed. It can be seen that the disassembly and maintenance operation of the panel 1 and the indicator light has many matters needing attention, and the operation is relatively difficult.

[0043] Compared with the prior art, the indicator light assembly provided in the embodiment sets the light guide column 2 in a curved shape, the first light guiding section 210 receives the light emitted by the light emitting assembly 4, and the light is emitted through the front end of the second light guiding section 220 after being transmitted in the light guide column 2, which meets the performance requirement of light emission to prompt the operator. Based on this, the installation mode of the indicator light assembly in the embodiment is that the light guide column 2 and the mounting bracket 3 are preassembled to the panel 1, and then the panel 1 is installed on the device main body under the premise that the upper side of the device main body is kept open. After the panel 1 is installed, the light emitting assembly 4 is installed on the upper side of the mounting bracket 3, the cable in the device main body is plugged with the wiring port 430 of the light emitting assembly 4 after the light emitting assembly 4 is installed, and the assembly is completed. When maintenance is needed, the panel 1 does not need to be disassembled, and the cable connected between the device main body and the light emitting assembly 4 is unplugged, and the light emitting assembly 4 can be directly disassembled from the upper side. It can be seen that the installation of the light guide column 2 and the mounting bracket 3 is divided into stages with the installation of the light emitting assembly 4, and in the assembly process, the installation of the panel 1 is prior to the conductive connection, the installation of the panel 1 is not affected by the cable, and the operation difficulty of the installation of the panel 1 is greatly reduced. When maintenance is needed, the panel 1 does not need to be disassembled, the light emitting assembly 4 can be directly disconnected from the device main body and disassembled, and the difficulty of the maintenance operation is also greatly reduced.

[0044] In some embodiments, referring toFigure 2 The light-in surface 211 at the upper end of the first light guide section 210 is a downwardly recessed curved surface corresponding to the indicating light source 420, which converges the light rays emitted by the indicating light source 420. Meanwhile, the recessed space formed by the curved surface allows the indicating light source 420 to be as close as possible to the first light guide section 210, so as to avoid excessive escape of the light rays emitted by the indicating light source 420.

[0045] In some embodiments, referring to Figure 2 The first light guide section 210 and the second light guide section 220 are connected by the arc-shaped connecting section 230, which not only makes the molding of the light guide column 2 easier, but also facilitates the efficient propagation of light and ensures the light brightness.

[0046] In some embodiments, referring to Figure 2 In the direction of light propagation, the diameter of the first light guide section 210 gradually decreases, so as to gradually converge the light and further improve the light brightness.

[0047] More specifically, in order to more efficiently converge the light, the outer surface of the first light guide section 210 and the outer surface of the connecting section 230 are smoothly connected, and the outer surface of the second light guide section 220 and the outer surface of the connecting section 230 are smoothly connected. In the direction of light propagation, the diameter of the first light guide section 210, the diameter of the connecting section 230, and the diameter of the second light guide section 220 gradually decrease, respectively.

[0048] In some embodiments, referring to Figure 2 The rear side of the light outlet hole 5 is provided with a stepped ring groove 6, and the outer periphery of the second light guide section 220 is provided with an axial limiting protrusion 240. The axial limiting protrusion 240 is inserted into the stepped ring groove 6 and can limit the displacement of the second light guide section 220 in the axial direction, so as to avoid the problem that the second light guide section is inserted too deeply and the structure is damaged. Optionally, the axial limiting protrusion 240 is a ring-shaped protrusion continuously distributed along the circumferential direction of the second light guide section, so that the circumferential stress of the second light guide section is more uniform. Further, the outer periphery contour line of the axial limiting protrusion 240 is circular, which reduces the stress concentration problem of the axial limiting protrusion 240 and avoids cracking and deformation of the axial limiting protrusion 240.

[0049] On the basis of the above embodiments, referring to Figure 2 The outer periphery of the stepped ring groove 6 is provided with at least one circumferential limiting groove 7, and the outer periphery of the axial limiting protrusion 240 is provided with a circumferential limiting protrusion 250. The circumferential limiting protrusion 250 is inserted into the circumferential limiting groove 7 to limit the displacement of the second light guide section 220 in the circumferential direction. After insertion, the second light guide section 220 will not rotate, and thus the light guide column as a whole has good structural stability after being inserted into the light outlet hole 5. When the mounting bracket 3 is assembled subsequently, the light guide column will not displace.

[0050] Optionally, the axial limiting protrusion 240 is arranged at the rear end of the second light guide section and is relatively close to the connecting section 230. The circumferential limiting protrusions 250 are arranged in multiple, and the multiple circumferential limiting protrusions 250 are uniformly distributed along the circumferential direction of the axial limiting protrusion 240, so as to improve the uniformity of stress and the reliability of limiting.

[0051] In some embodiments, referring to Figure 2 , the mounting bracket 3 comprises a connecting base plate 310 and an overhead base plate 320. The connecting base plate 310 is located above the second light guide section 220 and is connected to the rear side of the panel 1. The overhead base plate 320 is arranged at the upper edge of the connecting base plate 310 and extends backward. The light emitting assembly 4 is connected to the upper plate surface of the overhead base plate 320. The overhead base plate 320 is provided with a clearance gap 321 corresponding to the indicating light source 420. The light source plate 410 is detachably connected to the overhead base plate 320. When maintenance is required, the light emitting assembly 4 can be conveniently disassembled. The mounting bracket 3 of the embodiment is in the shape of an inverted L as a whole. It has a large combined area with the panel 1 and the light emitting assembly 4, respectively, and thus has good assembly stability and compact structure. Since the mounting bracket 3 is arranged above the second light guide section 220 and a clearance gap is formed between the connecting base plate 310 and the overhead base plate 320, interference with the light guide column 2 does not occur. At the same time, since the clearance gap 321 is provided, the light emitting performance of the light emitting assembly 4 is not affected.

[0052] In some embodiments, referring to Figure 2 , the light emitting assembly 4 comprises a light source plate 410, an indicating light source 420 arranged on the lower side of the light source plate 410, and a wiring port 430 arranged on the upper side of the light source plate 410. The light source plate 410 is fixedly connected to the overhead base plate 320 by a first fastener. The light emitting assembly 4 of the embodiment adopts a lower light emitting and upper wiring mode. It not only meets the light emitting requirement, but also meets the requirement of convenient cable plugging. The light emitting assembly 4 has better structural stability after being connected by the fixing mode of the first fastener.

[0053] Optionally, referring to Figure 2 , the light source plate 410 is provided with two groups of first mounting holes 411. The two groups of first mounting holes 411 are respectively arranged on the left and right sides of the indicating light source 420. The overhead base plate 320 is provided with two groups of second mounting holes 322. The second mounting holes 322 are respectively arranged on the left and right sides of the clearance gap 321. The first mounting holes 411 correspond to the second mounting holes 322 one by one. The first fastener penetrates the first mounting holes 411 and the second mounting holes 322 in sequence, so as to realize the connection of the light source plate 410 and the overhead base plate 320. The distribution mode of the first mounting holes 411 and the second mounting holes 322 makes the assembly stress of the light emitting assembly 4 more uniform. After assembly, the light source plate 410 is not easily deformed, so as to ensure the light emitting stability.

[0054] In specific implementation, the lower side of the second mounting hole 322 is provided with a fastening seat 323, and the first fastener is connected and matched with the fastening seat 323 after sequentially penetrating the first mounting hole 411 and the second mounting hole 322. Optionally, the first fastener is a threaded fastener, and the fastening seat 323 is correspondingly provided as a threaded seat; or the first fastener is a straight insertion type buckle, and the fastening seat 323 is provided as a clamping seat; and other examples are not listed one by one here.

After the mounting bracket 3 is connected with the panel 1, the limiting plate 330 can limit the displacement of the axial limiting protrusion 240 at the rear side of the axial limiting protrusion 240, so as to avoid the light guide column 2 from falling off the panel 1, and facilitate the disassembly of the panel 1 and the equipment main body.

[0056] Optionally, on the basis of the axial limiting protrusion 240, the circumferential limiting protrusion 250 can also be arranged according to the foregoing embodiments, which will not be described here.

[0057] In some embodiments, referring to Figure 2 , in order to make the assembly stress more uniform, the connecting base plate 310 is provided with a third mounting hole 311, the panel 1 is provided with a fourth mounting hole 101, and the connecting base plate 310 and the panel 1 are connected and fixed through the second fastener penetrating the third mounting hole 311 and the fourth mounting hole 101. Optionally, the third mounting hole 311 is provided with two groups, and the two groups of third mounting holes 311 are respectively arranged on the left and right sides of the limiting groove 340. Correspondingly, the fourth mounting hole 101 is provided with two groups, and the two groups of fourth mounting holes 101 are arranged on the left and right sides of the light emitting hole 5.

[0058] In specific implementation, the implementation mode of the second fastener includes but is not limited to a threaded fastener, a straight insertion type buckle, and the like, which will not be listed one by one here.
