Therefore, the advantages of optical fiber products such as luminous uniformity, brightness, color consistency and flexibility can meet this requirement. As an important light-entering component of luminous optical fiber, optical fiber crystal head plays an important role in the luminous effect and installation convenience of optical fiber.

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] like Figure 1 The optical fiber connector light source module shown mainly includes two parts, namely, an optical fiber connector assembly 100 and an optical fiber module assembly 200. Here, the optical fiber connector assembly 100 is composed of an optical fiber component 300 and a connecting component 400. The optical fiber component 300 is used for emitting light. The connecting component 400 is installed at one end of the optical fiber component 300 and its main function is to be used for connection. The optical fiber module assembly 200 is connected to the optical fiber component 300 through the connecting component 400. The optical fiber module assembly 200 is mainly used for emitting light. The optical fiber module assembly 200 has a luminous light source, which is transmitted through the optical fiber component 300 and makes the entire optical fiber component 300 emit light.

[0030] Specifically, the optical fiber component 300 includes an optical fiber 500 and a sheath 600. In order to achieve a good luminous effect, in the present patent, the optical fiber 500 is composed of a plurality of optical fiber filaments 700. The plurality of optical fiber filaments 700 are arranged in the sheath 600 and assembled into a single optical fiber 500. Here, the sheath 600 plays a protective role on the one hand, and on the other hand, the plurality of optical fiber filaments 700 can be integrated into a single optical fiber 500, and optical fibers 500 of different shapes can be produced according to the shape of the sheath 600.

[0031] like Figure 2 As shown, as a further optimization, in order to facilitate light emission and heat dissipation, the optical fiber module assembly 200 includes a heat dissipation seat 800, an upper cover 900, a circuit board 1000 and a light source 1001. The upper cover 900 is installed on the front of the heat dissipation seat 800, and the light source 1001 is installed on the circuit board 1000. The assembly consisting of the circuit board 1000 and the light source 1001 is installed in the installation space formed between the heat dissipation seat 800 and the upper cover 900. One end of the optical fiber extends into the upper cover 900 and aligns the light source 1001 with the optical fiber. Here, the light source 1001 mainly provides a light source. The light emitted by the light source 1001 is transmitted through the optical fiber and then emits light. The heat dissipation seat 800 in this patent provides an installation space for the light source 1001 on the one hand, and its main function on the other hand is heat dissipation.

[0032] As a further optimization, in order to facilitate the disassembly and portable installation of the upper cover 900 and the heat sink seat 800, the upper cover 900 has a plurality of card-mounting pieces 1002 on the circumferential edge, the card-mounting pieces 1002 have card-mounting grooves 1003, and the heat sink seat 800 is provided with card-mounting bosses 1004 assembled with the card-mounting grooves 1003 on the circumferential edge. When the card-mounting bosses 1004 are inserted into the card-mounting grooves 1003, the upper cover 900 and the heat sink seat 800 are combined and installed. As a further optimization, in order to ensure good sealing performance, as an optimization, a first rubber ring 1005 is also installed between the heat sink seat 800 and the upper cover 900.

[0033] As a further optimization, the heat generated by the light source is gathered on the heat sink, which causes the light source to fail or the performance to be reduced, thereby affecting the brightness of the optical fiber. In order to dissipate heat efficiently, a heat dissipation component is integrally connected to the rear of the heat sink 800, and the heat dissipation component is composed of a plurality of heat sinks 1006 distributed at intervals. In order to efficiently conduct the heat generated by the light source 1001, a thermal pad 1016 is also installed at the bottom of the circuit board 1000 inside the heat sink 800 in the patent, so that the heat generated on the circuit board 1000 can be conducted to the heat sink through the thermal pad 1016 for rapid heat dissipation. In the patent, the entire heat sink 800 is made of aluminum alloy and adopts a pin-column heat dissipation structure. 13 columnar heat sinks 1006 are distributed on it to cooperate with heat dissipation, which greatly reduces the volume and weight of the light source group, making the entire light source module lightweight while having a good heat dissipation effect. In addition, it can prevent the heat generated by the circuit board 1000 and the light source 1001 from converging on the heat sink 800, thereby causing the light source 1001 to fail or the performance to be reduced, thereby affecting the brightness of the optical fiber.

[0034] In order to facilitate the connection with the external control component, a connector 1007 connected to the external control component is provided on the heat dissipation component, and a connector pin 1008 is provided on the circuit board 1000. The connector pin 1008 is located in the connector 1007, and the outside of the connector 1007 has an assembly flange 1009. When in use, the control component can be controlled by simply snapping into the assembly flange 1009 and connecting it to the connector pin 1008 at the same time.

[0035] like Figure 3As shown, another innovation of the present invention is that the connecting component 400 includes a connector 1010, a snap-fit ​​component 1011 and a spring 1012. One end of a single optical fiber is inserted into the connector 1010, the snap-fit ​​component 1011 is sleeved on the connector 1010, the spring 1012 is sleeved on the connector 1010, and the two ends act on the connector 1010 and the snap-fit ​​component 1011 respectively. The snap-fit ​​component 1011 is installed and connected to the upper cover 900. Here, the connector 1010 is made of high-temperature resistant material to make an optical fiber connector, generally a metal material, which has a normal and effective high-temperature resistance (150°C) effect. In this way, the connector 1010 will not corrode under high temperature conditions, and it can ensure that the light source optical fiber has a good luminous effect. The snap-fit ​​component 1011 mainly plays the role of an intermediate connection, so that the entire optical fiber connector assembly 100 and the optical fiber module assembly 20 can be connected. 0 are connected together. In order to facilitate assembly and installation, a convex point 1013 is provided on the upper cover 900, and an L-shaped card groove 1014 is opened on the fastener 1011. After the optical fiber connector assembly 100 is inserted into the upper cover 900 of the optical fiber module assembly 200, the fastener 1011 is pushed to the bottom end and the fastener 1011 is rotated to make the card groove 1014 and the convex point 1013 of the upper cover 900 be clamped and fixedly connected. Here, the L-shaped card groove 1014 not only has an anti-slip function, but also can quickly assemble and connect the fastener 1011 and the upper cover 900. In order to ensure good sealing performance at the connection, a second rubber ring 1015 is installed between the upper cover 900 and the connector 1010. Through the connector 1010, the fastener 1011 and the second rubber ring 1015, it can achieve the required sealing and anti-slip effect while being resistant to high temperature.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
