Technical Field
[0001] The utility model relates to the technical field of luminous characters, in particular to a luminous character with a mixed light gradient effect. Background Art
[0002] LED letters are illuminated characters made using light-emitting diodes (LEDs). They offer numerous advantages, including beautiful appearance during the day, vibrant brightness at night, energy efficiency, and durability. They are commonly used in various billboards and signage applications, providing excellent visual guidance.
[0003] In the prior art, commonly used LED light-emitting characters are generally single-color, with white light being the main color. In order to improve the visual effect of these light-emitting characters, light-transmitting films of various colors are generally affixed to the light-transmitting plates of the light-emitting characters, so that the characters appear to have a variety of color visual effects. However, the affixed films are generally fixed to the position of the light-transmitting plates, so that the displayed light colors and gradient effects are static, which reduces the visual effect of the light-emitting characters. Utility Model Content
[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a luminous character with a mixed light gradient effect, so as to solve the technical problems mentioned in the above background technology.
[0005] The above technical objectives of the present invention are achieved through the following technical solutions:
[0006] A luminous character with a mixed light gradient effect, comprising a mounting cover, a circuit board, and a plurality of lamp beads, wherein the circuit board is fixedly mounted on the inner bottom side of the mounting cover, and the lamp beads are electrically connected to the circuit board. The top side of the mounting cover is provided with a mounting groove, and a color changing mechanism is provided on the top of the mounting groove;
[0007] The color-changing mechanism includes two rotating shafts, three-color light-transmitting belts and two secondary shafts. The two rotating shafts are rotatably installed at the two opposite ends in the mounting groove and are located above the circuit board. The two secondary shafts are respectively arranged on the sides of the rotating shafts. The two ends of the secondary shafts are rotatably connected to the corresponding inner side walls of the mounting grooves. The three-color light-transmitting belts are wrapped around the outer side walls of the two rotating shafts and the two secondary shafts, and the three-color light-transmitting belts pass between the rotating shafts and the secondary shafts on the same side. A driving motor is fixedly installed on the outer side wall of the mounting cover, and the output end of the driving motor is drivingly connected to the corresponding rotating shaft.
[0008] In a preferred example, the present invention can be further configured as follows: a protective plate is fixedly installed on the top side of the circuit board in the installation cover, and an avoidance groove is opened on the protective plate for avoiding the lamp beads.
[0009] In a preferred example, the present invention can be further configured as follows: light-blocking plates are fixedly connected to the two ends of the top side of the protective plate close to the two rotating shafts, and light-transmitting glass is connected between the top sides of the two light-blocking plates, and the sides of the light-blocking plates are in contact with the inner side walls of the mounting grooves, and the sides of the light-transmitting glass are in contact with the inner side walls of the mounting grooves.
[0010] In a preferred example, the present invention can be further configured as follows: a light-transmitting plate is fixedly connected to the top side of the installation groove, and a gap is left between the light-transmitting plate and the three-color light-transmitting strip.
[0011] In a preferred example, the present invention can be further configured as follows: the light-transmitting glass, the light-blocking plate and the light-transmitting plate are all sealed to the inner side wall of the installation groove by means of sealant.
[0012] In summary, the present invention has at least one of the following beneficial technical effects:
[0013] 1. This luminous character with a mixed light gradient effect can be used to continuously change and overlap the three basic colors by rotating the three-color translucent strip, thereby changing the color of the translucent light. This allows the luminous character to achieve a dynamic color transition gradient effect, improving the visual effect of the luminous character display;
[0014] 2. This luminous character with a mixed light gradient effect has a light-blocking plate to prevent light from hitting the edge of the mounting cover, which would cast shadows on the rotating shaft and secondary shaft, thereby reducing the display of the luminous character. Translucent glass is also provided to prevent air from coming into contact with the tri-color translucent strip near the mounting cover wiring, which would accelerate oxidation and reduce the service life of the tri-color translucent strip.
[0015] 3. This luminous character with a mixed light gradient effect has translucent glass, light-blocking plate, and translucent plate connected to the inner wall of the installation groove through sealant, which further improves the sealing inside the installation groove and reduces the contact between the three-color translucent strip and the outside air, avoiding oxidation caused by long-term contact with the outside air of the three-color translucent strip, thereby increasing the service life of the three-color translucent strip.

A drive motor 9 is fixedly installed on the outer wall of the mounting cover 1, and the output end of the drive motor 9 is drive-connected to the corresponding rotating shaft 6.
[0026] In the embodiment, the circuit board 2 is powered to make the lamp beads 3 emit light, the lamp beads 3 emit light as ordinary white light LED lamps, and then the motor 9 is driven to rotate the corresponding rotating shaft 6, thereby driving the three-color light transmission belt 7 to rotate, and then the lamp beads 3 will be reflected through the three-color light transmission belt 7, wherein the light emitted by the lamp beads 3 will pass through the double-layer distributed three-color light transmission belt 7 composed of three colors of basic three colors, and when the three-color light transmission belt 7 rotates continuously, different colors will gradually overlap, and the light will pass through two different colors to change into a new color, and meanwhile, as the three-color light transmission belt 7 continuously rotates, the basic three colors of the overlapping part will also continuously change, thereby gradually forming a new color, so that the place irradiated by the lamp beads 3 gradually changes color due to the change and overlap of the basic three colors, thereby achieving the effect of dynamic color gradient, and thereby improving the visual effect when the light-emitting character is displayed.
[0027] It should be known that the sub-shaft 8 is arranged to reduce the gap of the overlapping part of the three-color light transmission belt 7, thereby avoiding the effect of light scattering, thereby avoiding the influence of the visual effect of the display caused by the color disorder of the light, and the three-color light transmission belt 7 is of the same material as the light transmission film in the prior art.
