Patent Description:
The existing neon point control lamps are mainly based on LED patch lamp beads, while the traditional in-line LED lamps are <NUM>-wire carrier point control, which transmit signals through the power lines.

However, since the signals are transmitted through the power lines, the stability of the signals transmitted by the power lines will be affected by the power supply, resulting in that the maximum number of lamps having stable signal is currently less, and more lamps cannot be stabilized.

In-line type point control lamps and lamp string structures comprising two power lines and a signal line are disclosed in <CIT>, <CIT>, <CIT>, <CIT>, and <CIT>.

The purpose of the present invention is to provide an in-line type point control lamp and a lamp string structure, which solves the technical problem that the traditional point control lamps existed in the prior art transmit signals through power lines, and the stability of the signals transmitted by the power lines will be affected by the power supply, resulting in that the maximum number of lamps having stable signal is currently less, and more lamps cannot be stabilized.

In the first aspect, the present invention provides an in-line type point control lamp according to claim <NUM>.

In an optional embodiment,
any two of the three welding parts are the power connecting parts, and one of the three welding parts is the signal connecting part.
