[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] Reference Figure 1 and Figure 2 A novel light guide patch light strip according to an embodiment of the present invention includes a light strip body 10, which is composed of an inner core tube 100 and a covering layer 101. A light plate 102 is installed in the inner cavity 111 of the inner core tube 100, and the covering layer 101 is sleeved on the outer periphery of the inner core tube 100. The outer peripheral wall of the covering layer 101 has a light guide 109.

[0035] The inner core tube 100 is the structural foundation of the entire light strip body 10, and it has an inner cavity 111 extending along its length. The inner core tube 100 is preferably made of flexible plastic material and formed by extrusion, possessing good bendability to adapt to different installation scenarios and shape requirements. The cross-sectional shape of the inner core tube 100 includes a base 103 and shielding portions 104 extending from both sides of the base 103 towards the center. The two shielding portions 104 are not completely closed, retaining a narrow channel 105, which connects the inner cavity 111 to the external environment, allowing the light panel 102 to be installed in the inner cavity 111. In this embodiment, the outer peripheral wall of the base 103 is designed as an arc-shaped surface. In this embodiment, the overall cross-section of the inner core tube 100 is approximately semi-circular or "U"-shaped, and the channel 105 is the opening of this "U" shape.

[0036] The lamp board 102 is disposed within the inner cavity 111 of the inner core tube 100. The lamp board 102 is flexible, typically using a flexible printed circuit board, allowing it to bend along with the inner core tube 100 without damage. Multiple light sources 112 are spaced on the lamp board 102 using surface mount technology (i.e., SMD process). The light sources 112 are preferably high-brightness SMD LED chips. The lamp board 102 is attached to the inner plane of the base 103 of the inner core tube 100 by means of adhesive or bolt connection, ensuring its positional stability.

[0037] A conductor 106 is disposed within the base 103 of the inner core tube 100. The conductor 106 extends axially along the inner core tube 100 and is electrically connected to the circuit on the lamp board 102 to form a complete series or parallel circuit. In this embodiment, the conductor 106 is preferably a multi-strand copper wire to further enhance the flexibility of the lamp strip.

[0038] To meet outdoor safety standards and prevent electric shock and moisture intrusion, the covering layer 101 tightly wraps the inner core tube 100 using an extrusion coating process. It is understood that both the covering layer 101 and the inner core tube 100 are made of insulating, high-transmittance polymer material, allowing the light emitted from the light source 112 to shine outwards, achieving the lighting and decorative function. The covering layer 101 seals the inner core tube 100, the internal lamp panel 102, and the wires 106, forming an insulating and waterproof overall structure. The shape of the covering layer 101 basically follows the contour of the inner core tube 100, and a first support surface 107 is provided on the covering layer 101 corresponding to the position of the channel 105 of the inner core tube 100. In this embodiment, the first support surface 107 is planar.

[0039] Understandably, the light guide 109 is mounted on the first support surface 107. The light guide 109 is integrally fixed to the first support surface 107 of the covering layer 101 through injection molding. The light guide 109 is made of transparent optical-grade plastic, such as PMMA or PC. The light guide 109 extends radially outward along the inner core tube 100, forming shapes such as cylinders, square pillars, teardrops, or bulbs. The position of each light guide 109 corresponds to the position of a light source 112 on the lower light panel 102. Understandably, the light emitted by the light source 112 passes through the channel 105 of the inner core tube 100 and directly enters the bottom of the upper light guide 109. Then, guided and scattered by the light guide 109, it is evenly emitted in all directions, forming a bright and eye-catching light spot, thereby enhancing the lighting effect and visual aesthetics. Further, referring to... Figure 6 The light guide 109 can be formed by injection molding or stamping, and different textures, curved surfaces, protrusions or grooves can be formed on its surface during the molding process, thereby changing the direction of light emission and forming different lighting effects, which is conducive to improving the diversity and decorative effect of the product.

[0040] Furthermore, a light guide sleeve 110 is provided on the outer periphery of the covering layer 101. The light guide sleeve 110 and the light guide component 109 are integrally formed. When the light source 112 is turned on, the light can enter the light guide sleeve 110 from the light guide component 109, so that the light can propagate around the outer periphery of the covering layer 101, thereby making the outer periphery of the light strip emit light at the same time, which is beneficial to improving the lighting effect.

[0041] Furthermore, a second support surface 108 is provided on the top of the inner core tube 100, i.e., on the outer side of the two shielding portions 104. The second support surface 108 is planar, and it is located on the same side as the first support surface 107 of the covering layer 101. In this embodiment, the second support surface 108 is planar, and the first support surface 107 and the second support surface 108 are parallel to each other, which can enhance the stability of the structure and the connection between the inner core tube 100, the covering layer 101, and the light guide 109.

[0042] Furthermore, referring to Figure 3 and Figure 4 This utility model also includes a first connector 120 for realizing electrical connection between two adjacent segments of the LED strip body 10. The first connector 120 mainly consists of a sleeve 121, a cover 122, a waterproof sleeve 123, and a first connector 124. The sleeve 121 is usually cylindrical, with an opening at one end for the end of the LED strip body 10 to be inserted. The first connector 124 is disposed inside the sleeve 121 and includes an insulating substrate 125. A positioning piece 126 is provided on one side of the substrate 125 for locking the first connector 124 in a specific position inside the sleeve 121 to prevent it from moving. At both ends of the substrate 125, outwardly protruding conductive pins 127 are fixed, and the conductive pins 127 correspond to the wires 106 inside the LED strip body 10.

[0043] During connection, a cut section of the LED strip body 10 is inserted into one end of the sleeve 121, allowing the conductive needle 127 to pierce or contact the corresponding wire 106. Next, the waterproof sleeve 123 is fitted over the connection between the LED strip body 10 and the sleeve 121, and another section of the LED strip body 10 is connected to the other end of the sleeve 121 in the same manner. Finally, the cover 122 is screwed onto the external thread of the sleeve 121. As the cover 122 tightens, it compresses the waterproof sleeve 123 inwards. The waterproof sleeve 123, typically made of highly elastic silicone or rubber, tightly fills the gap between the outer wall of the LED strip body 10 and the inner wall of the sleeve 121 when compressed, thus achieving a waterproof seal.

[0044] Reference Figure 5The system also includes a second connector 119, which comprises a female connector 119-1 and a second connector 119-2. One end of the female connector 119-1 has a power cord for connecting to a power source. The second connector 119-2 is detachably installed inside the female connector 119-1, and a conductive pin 127 is inserted inside the second connector 119-2, with both ends of the conductive pin 127 extending out of the end of the second connector 119-2. When the second connector 119-2 is inserted into the second connector 119, one end of the conductive pin 127 can be electrically connected to the power cord, while the other end of the conductive pin 127 is used to connect to the light strip body 10 and electrically connect to the wire 106, thereby connecting the light strip body 10 to the power source. Understandably, the second connector 119 also includes a waterproof sleeve 123 and a cover 122. The waterproof sleeve 123 is located on one side of the light strip body 10 and can be embedded in the female connector 119-1. The cover 122 is threaded onto the outer periphery of the female connector 119-1 to achieve installation and waterproof sealing.

[0045] Reference Figure 7 and Figure 8 In a further embodiment, the outer periphery of the covering layer 101 may be provided with two opposing first support surfaces 107. Meanwhile, the lamp panel 102 uses a transparent flexible circuit board, and the light source 112 (i.e., SMD LED) on it also uses a transparent bracket model, so that light can be emitted simultaneously in both upward and downward directions. Then, light guides 109 are fixed to these two first support surfaces 107 respectively through injection molding, thereby forming a double-sided light strip, and its outer periphery light guide sleeve 110 can also guide the light propagation, giving it better visual performance in applications such as curtain lights and grid lights.

[0046] In summary, this utility model, through the unique structural design of the inner core tube 100, the covering layer 101, and the light guide 109, and the cooperation of the dedicated first connector 120, successfully provides a new type of light guide patch light strip that offers excellent luminous effect, safety and reliability, ease of installation, and suitability for mass production. It effectively solves the technical problems of insufficient brightness in traditional festival light strings, uneven light efficacy in flexible tubes, and the inability of early SMD light guide strips to meet safety regulations and mass production requirements.

[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
