LED eave lamp and method thereof

1 . An LED eave lamp, comprising:

a first conductor, a second conductor, and a lamp body, wherein, the first conductor comprises a first power supply line and a second power supply line which are insulated from each other, and the second conductor comprises a third power supply line and a fourth power supply line which are insulated from each other, the first power supply line and the third power supply line being the same long wire that has not been disconnected, and the second power supply line and the fourth power supply line being the same long wire that has not been disconnected;

the first conductor is penetrated from one side of the lamp body;

the second conductor extends out from the other side of the lamp body;

the lamp body comprises a circular printed circuit board (PCB) and LED eave lamp beads, and one side, facing away from the LED eave lamp beads, of the PCB is free of being provided with any circuit components; one side, facing away from the lamp beads, of the PCB and soldering position are covered with an adhesive after dispensing treatment;

the first conductor further comprises a first signal line;

the second conductor further comprises a second signal line;

the first signal line and the second signal line are two signal lines formed by disconnecting the same wire;

the lamp body further comprises a circular bottom plate for fixing the LED eave lamp; a plane where the bottom plate is located is perpendicular to the one side or the other side of the lamp body;

the bottom plate and the PCB are respectively located on both sides of a plane where the first conductor and the second conductor are located;

the bottom plate and the LED eave lamp beads are respectively located on both sides of the plane where the first conductor and the second conductor are located;

the PCB is soldered to soldering positions of a first conductor and a second conductor, the soldering positions being formed by peeling off insulating layers of the first conductor and the second conductor in advance;

one side, facing the soldering positions, of the PCB is provided with two protrusions; the protrusions of the PCB are for soldering operation at the soldering position; when the thickness of the protrusion is adjusted so that a thickness of the protrusion is equal to or approximately equal to a thickness of a peeled insulating layer of the first conductor; one side, facing away from the lamp beads, of the soldered PCB is just fitted to the plane where the first conductor and the second conductor are located, so as to avoid pseudo soldering caused by a situation that the PCB is jacked up by a part of the unpeeled insulating layer covered under the PCB when the PCB is soldered;

one side, facing the LED eave lamp beads, of the PCB is provided with a lens;

an outer diameter of the PCB is smaller than an outer diameter of the bottom plate; a maximum outer diameter of the PCB is larger than a maximum outer diameter of a region where the insulating layer is peeled off at the soldering position, so that a part of the unpeeled insulating layer is still covered under the PCB to protect the soldering position;

two positioning holes are formed at an outer edge of the PCB to position the PCB and the lens;

two lugs further extend out from a body of the bottom plate in a straight line direction of passing through a centroid thereof, and a mounting hole is formed at the center of each lug; and the LED eave lamp is fixed and mounted;

a first straight line where a connecting line of two mounting holes is located and a second straight line where a connecting line of the two positioning holes are located in the same plane perpendicular to the PCB and the bottom plate;

the two mounting holes are more located outside a plane where the PCB is located compared with the two positioning holes;

when the first conductor and the second conductor include two wires insulated from each other, one of the wires is used as a live wire or used for DC positive power supply, the other wire is used as a neutral wire or used for DC negative power supply, and the two wires insulated from each other are further configured to transmit signals to control an operating state of the lamp beads;

the first conductor further includes a third wire insulated from the first and the second wire and is located in the same plane as the first wire and the second wire;

the second conductor includes a third wire insulated from the first wire and the second wire, and is located in the same plane as the first wire and the second wire;

for the first conductor and the second conductor, two wires are used for the power supply lines and a third wire is used for the signal line; when the third wire is used for the signal line, the signal line is configured to be disconnected or not disconnected;

when not disconnected, the signal line acts as a bus and transmits signals to DIN in each LED unit on a lamp strip to control the operation of the lamp beads, without affecting the signal line transmitting signals to the lamp beads in the other LED units regardless of which lamp bead is operating properly; and at this time, all LED units are in parallel relationship; wherein the lamp strip includes a plurality of the lamp bodies thereon, and each lamp body and the first conductor and the second conductor on both sides thereof constitute one LED unit on the lamp strip; and

when disconnected, the signal line transmits signals to DIN in a first LED unit on the lamp strip to control the operation of lamp beads of the first LED unit, and outputs signals from DOUT in the first LED unit for transmission to other LED units in a subsequent stage.
