The embodiment relates to a linear lamp strip with two-way signal transmission, as shown in fig. 1, the linear lamp strip comprises a plurality of groups of lamp bead units 100, and the lamp bead units 100 are connected in series to form the lamp strip. When the lamp strip is used, the lamp strip is connected with an external controller, and control signals are input to the lamp strip through the external controller.
Specifically, as shown in fig. 1, each set of bead units 100 includes: a lamp bead 110 and a B lamp bead 120. The lamp beads A110 and the lamp beads B120 are respectively provided with an IC chip, a power positive pole pin 101, a power negative pole pin 102, a first signal input pin 103, a second signal input pin 104 and a signal output pin 105. First signal input pin 103, second signal input pin 104 and signal output pin 105 all with lamp pearl IC chip internal circuit connection. The external input signal and the first signal input pin 103 on the A lamp bead 110 and the second signal input pin 104 on the B lamp bead 120 can be in single-path or double-path parallel connection and are in circuit connection, and the signal output pin 105 on the A lamp bead 110 is in circuit connection with both the first signal input pin 103 on the B lamp bead 120 and the second signal input pin 104 of the A lamp bead 110 in the next group of lamp bead units 100. The signal output pin 105 on the B lamp bead 120 is in circuit connection with both the first signal input pin 103 of the a lamp bead 110 and the second signal input pin 104 of the B lamp bead 120 in the next group of lamp bead units 100. Several groups of the lamp bead units 100 are sequentially connected in the above-described connection manner.
Further, as shown in fig. 1, the IC chip receives the signal input by the first signal input pin 103 and the signal input by the second signal input pin 104, and the internal IC chip performs data comparison and analysis processing on the signals, and performs signal transmission on the rear lamp bead after the data comparison and analysis processing.
Further, as shown in fig. 1, a first signal line 200 and a second signal line 300 are arranged between the a lamp bead 110 and the B lamp bead 120; the first signal line 200 is disconnected with the middle of the bonding pads of the inner surfaces 104 and 105 of the A lamp beads 110, and is completely connected with the bonding pad of the inner surface 103 of the B lamp bead 120; the second signal line 300 is connected with the inner surface 103 of the A lamp bead 110 and is completely connected with the bonding pad, and is disconnected between the bonding pads on the surfaces of 104 and 105 in the B lamp bead 120.
It should be noted that, when the external controller transmits a signal to the light bar, the input control signal enters the first signal input pin 103 and the second signal input pin 104 of the a light bead 110, respectively. When the bead a 110 is not damaged, the first signal input pin 103 and the second signal input pin 104 receive the controller signal at the same time, at this time, the bead a IC chip performs data comparison and analysis processing on the signals input by the first signal input pin 103 and the second signal input pin 104 according to a pre-programmed working program (the programmed program is the prior art and is not described in detail here), and transmits the control signal from the signal output pin 105 of the bead a 110 to the bead B103 pin for data cascade transmission after the data comparison and analysis processing.
