In the existing running water taillights, after a single lamp bead is lit, the lit area formed on the panel is small. In order to reduce the visual granularity of the running water taillight, the number of lamp beads is large and the density is high, which increases the cost of the running water taillight.

[0023] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0024] See also Figures 1 to 4A running tail light comprises: a bottom plate 3 and a panel 4, two light-transmitting plates 5, a circuit board 6 and lamp beads 7; the panel 4 is mounted on the bottom plate 3, and a closed installation space is formed between the panel 4 and the bottom plate 3; the two light-transmitting plates 5 are mounted up and down in the installation space and are parallel to the bottom plate 3, and a wave pattern 41 is arranged on the upper side or the lower side of the light-transmitting plates 5, and the crest extension directions of the wave patterns of the two light-transmitting plates 5 are perpendicular to each other; the circuit board 6 is arranged in parallel on one side of the bottom plate 3 close to the light-transmitting plates 5, and the lamp beads 7 are mounted on the circuit board 6, and the circuit board 6 is used to control the switch of the lamp beads 7.

[0025] Through the above arrangement, the lighting area of ​​a single lamp bead 7 on the panel 4 is larger, which is beneficial to reducing the number of lamp beads 7 and reducing the density of the lamp beads 7.

[0026] In the present application, the light-transmitting plate 5 and the panel 4 are both made of transparent materials; the panel 4 can be installed on the base plate 3 by screws, and a sealing ring can be installed between the panel 4 and the base plate 3 to enhance the waterproof and dustproof performance of the water taillight; the upper side of the light-transmitting plate is the side of the light-transmitting plate facing away from the base plate, and the lower side of the light-transmitting plate is the side of the light-transmitting plate close to the base plate. One side of the light-transmitting plate is provided with wavy patterns, and the other side is a plane parallel to the base plate. The wave patterns 41 are formed by a plurality of closely arranged triangular prisms, the angle j of the trough of the wave patterns is 45 degrees, the thickness t from the wave crest of the wave patterns to the other side of the light-transmitting plate is 5 mm, and the principle of the light-transmitting plate 5 can refer to the transparent invisible plate (Fresnel diffuser). After a single lamp bead 7 is lit, the light is diffused by the light-transmitting plate 5 to form a larger lighting area on the surface of the panel 4, so that the spacing between the lamp beads 7 on the circuit board 6 can be appropriately enlarged, and the density of the lamp beads 7 is smaller than that of the existing flowing tail lights to reduce the amount of lamp beads 7; the lamp beads 7 can be LEDs, which are evenly installed on the circuit board 6, and have the advantages of high brightness and energy saving; when the flowing tail lights are lit, the circuit board 6 controls the orderly lighting of each lamp bead 7 to form a flowing water effect on the surface of the panel 4.

[0027] In one embodiment, see Figure 1 The wave patterns of the two light-transmitting plates are arranged opposite to each other. After the lamp bead emits light, the light enters the light-transmitting plate from the plane of the lower light-transmitting plate, and after being refracted twice by the wave patterns of the two light-transmitting plates, it is emitted from the plane of the upper light-transmitting plate. The two light-transmitting plates are in contact with each other, with a small gap, to ensure the uniformity of light.

[0028] In another embodiment, the wavy patterns are all arranged on the upper side of the corresponding light-transmitting plates.

[0029] In another embodiment, see Figure 5 The wavy patterns are all arranged on the lower side of the corresponding light-transmitting plate.

[0030] As an implementation method, the two light-transmitting plates 5 are in contact with each other, and the flowing water taillight further includes a mounting block 8, which is mounted on the side wall of the panel 4. The mounting block 8 supports the light-transmitting plates 5 to prevent the light-transmitting plates 5 from falling onto the circuit board 6.

[0031] The mounting block 8 can be bonded to the inner wall of the panel 4 by glue, and the mounting block is close to the edge of the light-transmitting plate 5 to prevent the mounting block from blocking the light of the lamp beads 7.

[0032] As an implementation method, the flowing water taillight also includes an adjustment mechanism 9 which can adjust the distance from the lamp bead 7 to the light-transmitting plate 5, and the adjustment mechanism 9 includes: a first threaded member 91 and a second threaded member 92; the first threaded member 91 is installed on the side of the circuit board 6 away from the light-transmitting plate 5; the second threaded member 92 vertically passes through the base plate 3 and is rotatably connected to the base plate 3, and the second threaded member 92 is threadedly connected to the first threaded member 91.

[0033] Through the above arrangement, the effect of the flowing water can be adjusted by the adjusting mechanism 9.

[0034] In the present application, the lighting area formed by the lamp bead 7 on the surface of the panel 4 is affected by the distance from the lamp bead 7 to the light-transmitting plate 5. By rotating the second threaded member 92, the second threaded member 92 and the first threaded member 91 rotate relative to each other, and the first threaded member 91 drives the circuit board 6 and the lamp bead 7 to move closer to or away from the light-transmitting plate 5 to adjust the flowing water effect of the flowing water taillight.

[0035] As an implementation method, a rotating groove penetrating through the inner and outer sides of the bottom plate 3 is provided on the bottom plate 3, and a limiting protrusion 10 is provided along the inner periphery of the rotating groove. The second threaded member 92 includes a rotating portion 921 and a stud portion 922. The rotating portion 921 is rotatably connected in the rotating groove, and an annular groove is provided along the outer periphery of the rotating portion 921. The limiting protrusion 10 is embedded in the annular groove. The stud portion 922 is coaxially fixedly connected to the rotating portion 921. The first threaded member 91 is provided as a threaded sleeve, and the stud portion 922 is threadedly connected in the threaded sleeve.

[0036] Through the above arrangement, the second threaded member 92 can be axially fixed in the rotation groove to prevent the circuit board 6 and the first threaded member 91 from shaking in the installation space.

[0037] In the present application, when the rotating groove is embedded in the annular groove, the rotating part 921 cannot move axially in the rotating groove, and the rotating part 921 can only rotate around the axis of the rotating groove. The second threaded member 92 is an integrally formed structure, and the second threaded member 92 can be rotated by a screwdriver.

[0038] As an implementation method, a guide groove 11 adapted to the first threaded member 91 is provided on one side of the bottom plate 3 close to the light-transmitting plate 5 , and an end of the first threaded member away from the circuit board 6 is slidably connected in the guide groove 11 .

[0039] Through the above arrangement, the stability of the movement of the first threaded member is improved.

[0040] As an implementation method, the running water tail light further includes a connecting piece 12 , which passes through the bottom plate 3 and is threadedly connected to the edge of the panel 4 to lock the panel 4 on the bottom plate 3 .
