[0044] The present invention provides a light guide structure for FTTR equipment. The FTTR equipment includes a housing 1 and a circuit board 2 disposed in the housing 1. The circuit board 2 is provided with at least one LED light 3. Figure 1-Figure 5 The light guide structure includes a light guide shell 4 and a light guide column 5; the light guide shell 4 is installed on the circuit board 2, and at least one light guide cavity 41 is provided in the light guide shell 4, and each light guide cavity 41 is corresponding to an LED lamp 3; a light guide surface 42 is provided on the inner side wall of the light guide cavity 41, and the light guide surface 42 is arranged opposite to the LED lamp 3; the light guide column 5 is installed on the shell 1; a light guide through hole 43 connected to the light guide cavity 41 is provided on the light guide shell 4, and the first end of the light guide through hole 43 faces the light guide surface 42, and the second end of the light guide through hole 43 faces the light guide column 5.

[0045] As an example, the light guide structure can be applied to FTTR, FTTR-B or broadband fusion terminal products, specifically in FTTR equipment. The light guide structure includes a light guide shell 4 and a light guide column 5; during installation, the light guide shell 4 is installed on the circuit board 2, and at least one light guide cavity 41 is provided in the light guide shell 4. Each light guide cavity 41 is provided corresponding to an LED lamp 3, so that the light emitted by the LED lamp 3 can be guided out through the light guide cavity 41 of the light guide shell 4, and at the same time, the light guide shell 4 can cover and hide the LED lamp 3 to effectively protect the LED lamp 3. For example, if the number of light guide cavities 41 is three, then three LED lamps 3 are provided on the circuit board 2. The light guide column 5 is installed on the housing 1, and specifically the light guide column 5 is fixed to the housing 1 by fasteners and is arranged opposite to the light guide shell 4, so that the light guided out of the light guide shell 4 can be evenly guided out of the housing 1 through the light guide column 5. A light-guiding surface 42 is provided on the inner wall of the light-guiding cavity 41, and the light-guiding surface 42 is arranged opposite to the LED lamp 3. At the same time, a light-guiding through hole 43 connected to the light-guiding cavity 41 is provided on the light-guiding shell 4, and the first end of the light-guiding through hole 43 faces the light-guiding surface 42, and the second end of the light-guiding through hole 43 faces the light-guiding column 5. In this arrangement, the positions of the LED lamp 3, the light-guiding surface 42 and the light-guiding through hole 43 are distributed in a triangular shape. When the light emitted by the LED lamp 3 corresponding to the light-guiding cavity 41 is irradiated on the light-guiding surface 42, it will be reflected, thereby changing the irradiation direction of the light. At this time, the light is irradiated on the light-guiding column 5 through the light-guiding through hole 43, and the light is evenly guided out through the light-guiding column 5, so that the user can clearly distinguish the status of the device with the naked eye.

[0046] In this example, the light guide shell 4 is installed on the circuit board 2, and the light guide cavity 41 in the light guide shell 4 is arranged in a one-to-one correspondence with the LED lamp 3 on the circuit board 2. The light guide shell 4 can cover and hide the LED lamp 3 to effectively protect the LED lamp 3 and prevent the LED lamp 3 from being damaged by external impact. When the light emitted by the LED lamp 3 is irradiated into the light guide cavity 41, a light guide surface 42 is set on the inner wall of the light guide cavity 41 at a position corresponding to the LED lamp 3, and the irradiation direction of the light is changed by the reflection principle. At this time, the light is irradiated onto the light guide column 5 through the light guide through hole 43, and the light is evenly guided out by the light guide column 5, so that the user can clearly distinguish the status of the device with the naked eye. Compared with the existing technology, the light guide structure in this example can achieve no light source restriction and can achieve light output at multiple angles. The light guide structure is installed and fixed by welding or screwing, which simplifies installation and disassembly, enhances stability, and facilitates maintenance. On the premise of ensuring that the light emitted by the LED lamp 3 can be guided out, it can also effectively protect the LED lamp 3 and prevent the LED lamp 3 from being damaged by external impact.

[0047] In one embodiment, referring to Figure 1 、 Figure 3 and Figure 5 The light guide shell 4 includes a shell frame 44 and at least two partitions 45; the shell frame 44 is installed on the circuit board 2, and an inclined surface is provided on the portion of the shell frame 44 facing the circuit board 2; the light guide surface 42 is provided on the inclined surface, and the light guide through hole 43 is provided at a position of the shell frame 44 corresponding to the inclined surface; at least two partitions 45 are arranged at intervals along the length direction of the light guide shell 4, and two adjacent partitions 45 cooperate with the shell frame 44 to form a light guide cavity 41.

[0048] The length direction of the light guide shell 4 is the length direction of the circuit board 2 , which can also be said to be a direction perpendicular to the axial direction of the light guide column 5 .

During installation, the shell frame 44 is installed on the circuit board 2, and an inclined surface is provided on the portion of the shell frame 44 facing the circuit board 2. The light guide surface 42 is provided on the inclined surface, and the light guide hole 43 is provided at a position of the shell frame 44 corresponding to the inclined surface. In this arrangement, the light emitted by the LED lamp 3 can be irradiated onto the inclined surface of the shell frame 44. The light is reflected by the light guide surface 42 on the inclined surface, and the irradiation direction of the light is changed by the reflection principle. At this time, the light is irradiated onto the light guide column 5 through the light guide hole 43. The light is evenly guided out by the light guide column 5, so that the user can clearly distinguish the status of the device with the naked eye. In addition, the shell frame 44 is a semi-enclosed structure, and at least two partitions 45 are arranged at intervals along the length direction of the light guide shell 4. The two adjacent partitions 45 cooperate with the shell frame 44 to form a light guide cavity 41. In this way, the light emitted by the LED lamp 3 can be guided out through the light guide cavity 41 of the light guide shell 4. At the same time, the light guide shell 4 can cover and hide the LED lamp 3 to effectively protect the LED lamp 3. For example, there are five partitions 45, and the five partitions 45 are spaced apart along the length direction of the light guide shell 4 to form three light guide cavities 41. Three LED lamps 3 are provided on the circuit board 2, and each light guide cavity 41 corresponds to an LED lamp 3. The partitions 45 can play a supporting role to protect the LED lamp 3 from external force impact. Each light guide cavity 41 is an independent cavity, which can prevent the light from leaking out.

[0051] The width direction of the light guide shell 4 and the length direction of the light guide shell 4 are two perpendicular directions. The width direction of the light guide shell 4 is the width direction of the circuit board 2 , which can also be said to be the direction of the axis direction of the light guide column 5 .

[0052] As an example, the housing 44 includes a first support plate 441, a second support plate 442 and a third support plate 443; when installed, the first support plate 441 and the second support plate 442 are spaced apart along the width direction of the light guide housing 4; the first side of the first support plate 441 is installed on the circuit board 2, the first side of the third support plate 443 is connected to the second side of the first support plate 441, and the angle between the third support plate 443 and the first support plate 441 is an obtuse angle; the first side of the second support plate 442 is installed on the circuit board 2, the second side of the third support plate 443 is connected to the second side of the second support plate 442, and the third support plate 443 is connected to the second support plate 44 2 is an acute angle; in this arrangement, the third support plate 443 is an inclined plate, the inclined surface is arranged on the inner wall of the third support plate 443, the light guiding surface 42 is arranged on the inclined surface, and the light guiding through hole 43 is arranged on the second support plate 442, so that the positions of the LED lamp 3, the light guiding surface 42 and the light guiding through hole 43 are distributed in a triangular shape. When the light emitted by the LED lamp 3 corresponding to the light guiding cavity 41 is irradiated on the light guiding surface 42, reflection will occur, thereby changing the irradiation direction of the light. At this time, the light is irradiated on the light guiding column 5 through the light guiding through hole 43, and the light is evenly guided out through the light guiding column 5, so that the user can clearly distinguish the status of the device with the naked eye. At least two partitions 45 are spaced apart along the length direction of the light guide shell 4 between the first support plate 441, the second support plate 442 and the third support plate 443, and the two adjacent partitions 45 cooperate with the first support plate 441, the second support plate 442 and the third support plate 443 to form a light guide cavity 41; in this way, the light emitted by the LED lamp 3 can be guided out through the light guide cavity 41 of the light guide shell 4, and at the same time, the light guide shell 4 can cover and hide the LED lamp 3 to effectively protect the LED lamp 3.

[0053] In one embodiment, referring to Figure 1 、 Figure 3 and Figure 5 The shell frame 44 also includes a fourth support plate 444; the first side of the fourth support plate 444 is connected to the second side of the third support plate 443, the second side of the fourth support plate 444 is connected to the second side of the second support plate 442, the angle between the fourth support plate 444 and the third support plate 443 is an obtuse angle, and the angle between the fourth support plate 444 and the second support plate 442 is a right angle.

[0055] In one embodiment, a reflective material layer is disposed on the light guiding surface 42 .

[0056] As an example, a reflective material layer is provided on the light-guiding surface 42, which can effectively reflect the light irradiated onto the light-guiding surface 42. Specifically, the light-guiding surface 42 is made of a white diffuse reflective material with a reflectivity ≥ 85%, and the reflection uniformity of the material within the wavelength range of 400-700nm is ≤ 3%. This setting can improve the reflective effect of the light-guiding surface 42 and provide convenience for guiding the light emitted by the LED lamp 3 out.

[0057] In one embodiment, the light guide column 5 is made of a transparent or milky white material with a transmittance ≥ 85% and a haze value ≤ 3%, and the light scattering uniformity of the material within the wavelength range of 400-700nm is ≤ 5%; such a setting can improve the light guiding effect of the light guide column 5 and provide convenience for guiding the light emitted by the LED lamp 3.

[0059] As an example, a first through hole 11 is provided on the shell 1; the light guide column 5 includes a main body plate 51 and a column 52, and the column 52 is a component extending from one side of the main body plate 51 in a direction perpendicular to the main body plate 51; during installation, the column 52 is first passed through the first through hole 11, which can guide the light to the outside world, and also provide a guide limit for the installation of the light guide column 5; then the main body plate 51 is installed on the shell 1, specifically, a first mounting hole is provided on the main body plate 51, and a second mounting hole is provided on the shell 1, and fasteners are passed through the first mounting hole and the second mounting hole to achieve the installation of the main body plate 51 on the shell 1; the part of the other side of the main body plate 51 corresponding to the column 52 is arranged corresponding to the light guide through hole 43, so that light can be irradiated from the light guide through hole 43 to the main body plate 51, and then the light is evenly guided out through the column 52, so that the user can clearly distinguish the status of the device with the naked eye.

[0060] In one embodiment, referring to Figure 1 and Figure 5 The light-guiding structure further includes a light-shielding foam 6, which is arranged on the light-guiding column 5 and located between the light-guiding shell 4 and the light-guiding column 5; a second through hole 61 is provided on the light-shielding foam 6, and the second through hole 61 is concentrically arranged with the light-guiding through hole 43.

[0061] As an example, the light-guiding structure also includes a light-shielding foam 6. During installation, in the case of multiple LED lamps 3, the light-shielding foam 6 is placed on the light-guiding column 5, between the light-guiding shell 4 and the light-guiding column 5, to effectively block light. A second through-hole 61 is provided in the light-shielding foam 6, which is concentric with the light-guiding through-hole 43. In this way, light is sequentially irradiated onto the light-guiding column 5 through the light-guiding through-hole 43 and the first through-hole 11, thereby preventing light leakage and crosstalk from the device. The light-shielding foam 6 is made of EVA foam with a light-shielding rate of ≥90% and a density of 20-30 kg / m³. The EVA foam has a light transmittance of ≤2% within the wavelength range of 400-700 nm. This ensures the light-shielding effect of the light-shielding foam 6, preventing light leakage and crosstalk from the device.

[0062] The present invention provides an FTTR device, referring to Figure 1 、 Figure 3 and Figure 5 , including a shell 1, a circuit board 2, an LED lamp 3 and a light guide structure; the circuit board 2 is installed in the shell 1, and the LED lamp 3 is installed on the circuit board 2; the light guide shell 4 is installed on the circuit board 2, and the light guide column 5 is installed on the shell 1.

This light guide structure can be used in FTTR, FTTR-B, or broadband converged terminal products, specifically in FTTR devices. The light guide structure includes a light guide housing 4 and a light guide column 5. During installation, the light guide housing 4 is mounted on the circuit board 2. At least one light guide cavity 41 is provided within the light guide housing 4, and each light guide cavity 41 corresponds to an LED lamp 3. This allows light emitted by the LED lamp 3 to be guided through the light guide cavity 41 of the light guide housing 4. The light guide housing 4 also conceals and protects the LED lamp 3, effectively protecting it. For example, if there are three light guide cavities 41, then three LED lamps 3 are provided on the circuit board 2. The light guide column 5 is mounted on the housing 1. Specifically, the light guide column 5 is fixed to the housing 1 via fasteners and is positioned opposite the light guide housing 4. This allows the light emitted by the light guide housing 4 to be evenly guided out of the housing 1 through the light guide column 5. A light-guiding surface 42 is provided on the inner wall of the light-guiding cavity 41, and the light-guiding surface 42 is arranged opposite to the LED lamp 3.

When the light emitted by the LED lamp 3 corresponding to the light-guiding cavity 41 is irradiated on the light-guiding surface 42, it will be reflected, thereby changing the irradiation direction of the light. At this time, the light is irradiated on the light-guiding column 5 through the light-guiding through hole 43, and the light is evenly guided out through the light-guiding column 5, so that the user can clearly distinguish the status of the device with the naked eye.

[0064] In this example, the light guide shell 4 is installed on the circuit board 2, and the light guide cavity 41 in the light guide shell 4 is arranged in a one-to-one correspondence with the LED lamp 3 on the circuit board 2. The light guide shell 4 can cover and hide the LED lamp 3 to effectively protect the LED lamp 3 and prevent the LED lamp 3 from being damaged by external impact. When the light emitted by the LED lamp 3 is irradiated into the light guide cavity 41, a light guide surface 42 is set on the inner wall of the light guide cavity 41 at a position corresponding to the LED lamp 3, and the irradiation direction of the light is changed by the reflection principle. At this time, the light is irradiated onto the light guide column 5 through the light guide through hole 43, and the light is evenly guided out by the light guide column 5, so that the user can clearly distinguish the status of the device with the naked eye. Compared with the existing technology, the light guide structure in this example can achieve no light source restriction and can achieve light output at multiple angles. The light guide structure is installed and fixed by welding or screwing, which simplifies installation and disassembly, enhances stability, and facilitates maintenance. On the premise of ensuring that the light emitted by the LED lamp 3 can be guided out, it can also effectively protect the LED lamp 3 and prevent the LED lamp 3 from being damaged by external impact.
