Problems solved by technology

[0002] At present, most breakpoint resume ICs use an additional signal line to achieve dual signal transmission, which solves the problem that the overall display effect will not be affected when a single lamp bead is damaged. However, if multiple lamp beads are damaged, it will still cause damage. The lamp beads behind are out of control

Embodiment

[0037] During specific implementation, the power conversion chip 3 can input a wide range of voltage, the input voltage range is 9-40V, and can be converted into a 5V output voltage to supply power to the bidirectional data transmission IC chip and three LED light emitting units. Such as Figure 4 As shown, in the actual application, two LED light-emitting units are damaged. In this embodiment, the LED lamp bead with an internally sealed IC with resumed bidirectional data transmission of the present invention is adopted, (using SDI / O input data The auxiliary input port FA) can effectively avoid affecting the global LED display.

[0038] The SDA terminal of the controller is connected to the SDI / O pin of the first-level breakpoint resume bidirectional data transmission IC chip. The data input by the SDI / O terminal is divided into two parts, and one part is output in parallel by the breakpoint resume bidirectional data transmission IC chip. to three LED light-emitting chips, an...

Abstract

The invention provides an LED lamp bead with an internally-packaged IC for breakpoint resume bidirectional data transmission. The LED lamp bead comprises a power conversion chip, a breakpoint resume bidirectional data transmission IC chip, three LED light emitting units and a packaging carrier, wherein the power conversion chip is connected with the breakpoint resume bidirectional data transmission IC chip and the three LED light-emitting units through metal wires, and three parallel output pins of the breakpoint resume bidirectional data transmission IC chip are connected with the three LED light-emitting units through metal wires; the packaging carrier is provided with metal conductive pads connected with the pins, the three LED light-emitting units, the breakpoint resume bidirectional data transmission IC chip and the power conversion chip are fixedly arranged on the metal conductive pads and fixed to the packaging carrier through packaging glue, and the pins on the packaging carrier are spaced through insulators. According to the technical scheme, the problem that normal use of all lamp beads behind a plurality of LED lamp beads is affected due to damage of the LED lamp beads in the prior art is solved, and global LED display is effectively prevented from being affected.

Description

technical field [0001] The present invention relates to the technical field of LED resumable transmission ICs, in particular to an LED lamp bead with bidirectional data transmission with resumable transmission and an internal IC. Background technique [0002] At present, most breakpoint resume ICs use an additional signal line to achieve dual signal transmission, which solves the problem that the overall display effect will not be affected when a single lamp bead is damaged, but if multiple lamp beads are damaged, it will still cause damage. The lamp beads behind are out of control. Contents of the invention [0003] According to the technical problem raised above, an LED lamp bead with an internal IC encapsulation and bidirectional data transmission with resumable transmission is provided. The technical means adopted in the present invention are as follows: [0004] An IC-enclosed LED lamp bead with resumed bidirectional data transmission includes: a power conversion ch...
