[0020] like Figure 1-4As shown, the high-refresh-rate HD video line light includes a main light body 1, a cover 2, a plug, a junction box 3, and several LED light panels 4. The LED light panels 4 and the cover 2 are sequentially mounted on the upper end of the main light body 1, and the junction box 3 is mounted on the bottom of the main light body 1. The junction box 3 is electrically connected to the LED light panel 4 and the plug, respectively. A power module 5, a step-down module 6, and a decoding module 7 are provided within the junction box 3. The power module 5 outputs power to the decoding module 7 through the step-down module 6. The decoding module 7 receives and decodes external input signals, and after decoding, outputs power and decoded signals to the LED light panel 4. It is understandable that the main light body 1 and the cover 2 can both be made of aluminum alloy, etc.; the power module 5 can be a universal lamp driver power supply, etc., and the step-down module 6 can be a universal power step-down module, etc., for outputting the rated voltage.

[0021] Specifically, the LED lamp board 4 is provided with a plurality of LED lamp beads, which are plug-in LED lamp beads 8 or SMD LED lamp beads 9, and the SMD LED lamp beads 9 are provided with a PC flame retardant protective mask; the plug includes a male plug 10 and a female plug 11 respectively arranged at both ends of the junction box 3, and the end of the main lamp body 1 is connected to a plug 12 by a fixing screw, and the bottom of the main lamp body 1 is installed with a spring bracket 13 and a flat bracket 14. There are many installation methods, which can be installed through the spring bracket 13 and the flat bracket 14, or by setting a clamp, which is not limited by the present utility model.

[0022] Specifically, the decoding module 7 includes a decoding chip P1. The decoded signal includes a data clock DCLK signal, a grayscale clock GCLK signal, a latch LAT signal, and a data SD signal. The plug uses a five-pin connector. The power module 5 is connected to a 48V power supply through the five-pin connector to power the step-down module 6. The step-down module 6 is electrically connected to the power module 5 and the decoding module respectively. The external input signal is an SPI signal or a DMX signal. The LED light board 4 is provided with a shaping chip U1 and several LED driver chips. The LED driver chips include LED driver chips U2, LED driver chips U3, LED driver chips U4, LED driver chips U5, etc. After the decoded signal is input to the LED light board 4, it is shaped by the shaping chip U1 and then output to the LED driver chip for signal data processing to control and drive the LED lamp beads. It is understandable that the shaping chip U1 can be an SM245 chip, etc., and the LED driver chip can be an MBI5043 chip, etc.

[0023] It can be understood that during implementation, the junction box 3 is connected to the external controller through a plug. When the external input signal is an SPI signal, the 48V power supply output electricity is supplied to the internal step-down module 6 through the five-core connector. The controller outputs the SPI network signal, which is decoded by the internal 100M decoding module 7 through the five-core connector. The power supply supplies power to the decoding module 7 through the step-down module 6, and outputs power and decoding signals to the LED light board 4 through the 8P pin. After the decoding signal is input to the LED light board 4, it is shaped by the SM245 chip and output to the MBI5043 chip for data processing to drive the LED lamp beads; when the external input signal is a DMX signal, the 48V power supply and the controller output DMX512 signal are supplied to the internal step-down module 6 and the decoding module 7 through the five-core connector for signal decoding. After the decoding is completed, the power supply and decoding signal are output to the LED light board 4 through the 6P pin. After the decoding signal is input to the LED light board 4, it is shaped by the SM245 chip and output to the MBI5043 chip for data processing to drive the LED lamp beads.

[0024] It can be understood that the present invention has a reasonable design and a unique structure. By setting a decoding module 7 to output a decoding signal to drive and control the working state of the LED light board 4, the refresh rate of the linear light can be improved, and the dynamic images or videos can be displayed more smoothly and clearly, thereby improving the quality and viewing experience of the visual effects; and by setting a plug to connect multiple groups of linear lights, the number of serial connections of the linear lights can be increased, thereby meeting actual application needs.
