[0041] The shell 10 is a structure for accommodating and protecting the lamp panel 20 and related components, and the shell 10 is provided with a mounting cavity 11 for accommodating the lamp panel 20, and a wire passage 12 is provided on the shell 10 for the wire to pass through. The material of the shell 10 can be a light-transmitting material, and the light-transmitting surface is arranged corresponding to the light-emitting side of the lamp panel 20, so as to diffuse the light source of the lamp panel 20 to the outside. The shell 10 generally includes a base 14 and a light-transmitting cover 15, the lamp panel 20 is mounted on the base 14, and the light-transmitting cover 15 is arranged corresponding to the light-emitting side of the lamp panel 20, and the base 14 and the light-transmitting cover 15 can be integrally injection molded or separately manufactured. When the base 14 and the light-transmitting cover 15 are separately manufactured, a clamping mode can be adopted for quick assembly and disassembly.

[0042] The lamp panel 20 is a component for installing LED (Light Emitting Diode) lamp beads, and plays a role of illumination. The lamp panel 20 can adopt a PCB (Printed Circuit Board) structure, install a plurality of LED lamp beads, and be welded with wires. A plane where the lamp panel 20 is located is set as a reference surface 21, and the reference surface 21 is generally parallel to the mounting surface of the base 14.

[0043] The wire passage 12 at least includes a first section 121 and a second section 123, the first section 121 and the second section 123 are arranged at an angle with respect to the extension direction, and the extension directions of the first section 121 and the second section 123 are respectively arranged at an angle with respect to the reference surface 21, which means that the wire starts from the lamp panel 20, passes through the second section 123, and passes through at least two corners, so as to improve the limiting ability of the wire in the extension direction thereof.

Secondly, the wire passage 12 can be arranged on the top wall of the shell 10, or can be arranged on the side wall 13 of the shell 10, which is not limited herein.

[0044] The utility model discloses a lamp body 100 passes through setting the wire passing channel 12 for the wire to set on the casing 10, and wire passing channel 12 at least includes first segment 121 and second segment 123, and first segment 121 and second segment 123 are arranged with the extension direction angle setting, and first segment 121 and second segment 123 are arranged with the reference surface 21 of the lamp panel 20 angle setting respectively, so that the wire forms the bending structure in the extension direction, that is, the wire forms the preliminary bending when passing through first segment 121, and further bending after passing second segment 123. Compared with the linear type setting of wire passing channel 12, the wire passing channel 12 of the utility model is the bending structure, and due to the bending angle increase, the friction between the wire and casing 10 increases, so that the wire cannot slide freely, thereby improve the limiting ability of casing 10 to the wire in its extension direction. Further, the improvement of wire limiting performance directly prevents the displacement of lamp panel 20 due to the wire loosening, and the lamp panel 20 will not be affected by external force pulling or vibration, ensuring the stability and illumination effect of lamp panel 20. Secondly, since wire passing channel 12 is bent, when moisture enters wire passing channel 12 through the wire passing hole of the wire, the bending section in wire passing channel 12 will accumulate moisture to prevent moisture from entering the mounting cavity 11 of casing 10, if wire passing channel 12 is linear, then moisture can directly enter the mounting cavity 11 of casing 10 through the wire passing hole of the wire, thereby affecting the service life of lamp panel 20.

[0045] Further, wire passing channel 12 also includes third segment 124, and the opposite ends of third segment 124 are respectively arc-shapedly connected to first segment 121 and second segment 123.

[0047] Further, first segment 121 is close to lamp panel 20, and wire passing channel 12 also includes fourth segment 125, fourth segment 125 is connected to one end of second segment 123 away from third segment 124, fourth segment 125 is close to the end of casing 10, and the extension direction of fourth segment 125 is parallel to reference surface 21.

[0048] In the embodiment, the fourth section 125 is close to the end of the shell 10, and the extension direction of the fourth section 125 is parallel to the reference surface 21, so that the wire is horizontally led out of the shell 10. On the basis of limiting the extension direction of the wire, the outlet direction of the wire is adjusted to realize parallel connection of adjacent lamp bodies 100 in the lamp string.

The protrusion 141 is arranged on the splicing surface 148, and the groove 151 corresponding to the protrusion 141 is arranged on the matching surface 155. Through the cooperation of the protrusion 141 and the groove 151, a bending area in the physical structure is formed, and the wire passing channel 12 is located in the area, so that the wire can be guided to pass through the bending area. When the wire passes through, the structure restricts the wire from moving randomly, so as to ensure the stability of the wire in the wire passing channel 12. That is, the bending structure can effectively prevent the wire from loosening or shifting, enhance the stability of the wire, and ensure the fixed connection of the lamp panel 20 and the shell 10.

[0053] Secondly, the shell 10 comprises the base 14 and the light-transmitting cover 15, and the two can be connected through buckling or threads, which is not limited herein.

[0055] In the embodiment, the extension direction of the wire passing channel 12 is the length direction of the wire, preferably, the first direction, the extension direction of the wire passing channel 12 and the normal direction of the reference surface 21 are all perpendicular to each other. The first sub-slot 142 and the second sub-slot 152 are both arc-shaped slots, the first sub-slots 142 arranged continuously along the first direction are similar to sawteeth.

The plurality of sub-channels 126 are arranged continuously, which provides independent limiting spaces for the wires of the flat cable structure and improves the stability of the wires. In addition, the slot wall between two adjacent first sub-slots 142 forms the limiting wall 16 between two adjacent sub-channels 126, which ensures that the wires between the adjacent sub-channels 126 do not interfere with each other, and the limiting wall 16 increases the contact area between the shell 10 and the wires and increases the friction between them, which further plays a limiting role.

[0056] Further, the splicing surface 148 is provided with two positioning blocks 143, the two positioning blocks 143 are connected to the opposite two side walls 13 of the protrusion 141 along the first direction respectively, the positioning block 143 is higher than the top of the protrusion 141, and the wire is located between the two positioning blocks 143.

During the installation process, the two positioning blocks 143 preliminarily limit the wire to prevent the wire from moving along the first direction.

[0058] Referring to Figures 1 to 3In an embodiment, the inner wall of the base 14 is provided with a mounting groove 144 extending along the circumference of the base 14, the light-transmitting cover 15 is embedded in the mounting groove 144, and the bottom wall of the mounting groove 144 is provided with a through hole 145; the side wall 13 of the mounting groove 144 close to the light-transmitting cover 15 is provided with a guide inclined surface 146 facing the lamp panel 20, and the guide inclined surface 146 is located outside the light-transmitting cover 15, and the light-transmitting cover 15 and the guide inclined surface 146 form a water outlet gap 147 communicating with the through hole 145.

[0059] In the embodiment, the mounting groove 144 extends along the circumference of the base 14, and the light-transmitting cover 15 is embedded in the mounting groove 144 to ensure the close connection between the light-transmitting cover 15 and the base 14. Meanwhile, the side wall 13 of the mounting groove 144 located inside the light-transmitting cover 15 can play a certain waterproof role.

[0060] Secondly, the bottom wall of the mounting groove 144 is provided with a through hole 145, the guide inclined surface 146 is inclined from the top of the light-transmitting cover 15 to the base 14 and faces the lamp panel 20, and is located outside the light-transmitting cover 15, and the guide inclined surface 146 and the light-transmitting cover 15 form a water outlet gap 147 communicating with the through hole 145, thereby forming a water flow guiding path to ensure that the water flow can flow to the water outlet gap 147 guided by the guide inclined surface 146 and be discharged through the through hole 145, avoiding the water entering the light-transmitting cover 15 and protecting the lamp panel 20 and the circuit system from being damaged by water, and improving the waterproof performance of the lamp body 100.

[0061] In an embodiment, the light-transmitting cover 15 includes a cover ring 153 and a light-transmitting lens 154, the cover ring 153 surrounds the light-transmitting lens 154 and is connected to the bottom plate, the light-transmitting cover 15 is arranged corresponding to the light-emitting side of the lamp panel 20, and the light-transmitting lens 154 is convex relative to the cover ring 153; the ratio of the outer diameter of the cover ring 153 to the diameter of the light-transmitting lens 154 is greater than or equal to 1.2 and less than or equal to 1.4.

The design that the light-transmitting lens 154 is convex relative to the cover ring 153 helps to enhance the refraction and diffusion effect of light. The convex light-transmitting lens 154 can better utilize the light source, increase the divergence angle of light, and provide more uniform and extensive illumination.

[0063] Secondly, the ratio of the outer diameter of the cover ring 153 to the diameter of the light-transmitting lens 154 is set between 1.2 and 1.4, and the diameter of the light-transmitting cover 15 is relatively large, which means that the surface area of the light-transmitting cover 15 is increased, and light can be scattered more effectively. Wide-range light scattering not only improves the uniformity of illumination, but also reduces the glare caused by direct light, thereby achieving a softer and more comfortable lighting effect. For example, if the ratio is too small, i.e., the light-transmitting lens 154 is too large, the light will be scattered too much, and the lighting effect will be weakened. If the ratio is too large, i.e., the light-transmitting lens 154 is too small, the light may not be scattered enough, and the lighting effect will be uneven.
