When the first terminal of the power connection terminal 103 is connected to the power output terminal of the external power supply and the second terminal is connected to the ground terminal of the external power supply, each light-emitting unit 102 forms a loop with the external power supply, so each light-emitting unit 102 emits light. , if the drive of the external power supply is insufficient, the external power supply can be increased. For example, if the current external power supply is the first external power supply, and the power connection terminal connected to the first external power supply is set as the first power supply connection terminal, it can be A second external power supply is externally connected to other power supply connection terminals other than a power supply connection terminal, so as to improve the driving capability and increase the brightness of the light-emitting unit 102 . Please continue to refer to FIG. 1 , a cutting line 104 is set between each adjacent light-emitting unit 102. For the convenience of manufacture, a cutting line 104 can also be set on the side of the light-emitting unit 102 outside the PCB board 101 close to the edge of the PCB board 101, The user can cut the PCB board 101 into different parts along the cutting line 104 . It can be understood that, in order to facilitate subsequent access to the external power supply, each cut part may include at least one power connection terminal 103. When the cut parts need to be spliced into a user-defined shape, the different parts can be The power connection terminals 103 are respectively connected to external power sources, and then different parts are combined into different shapes to adapt to different lighting or display environments.

Optionally, referring to FIG. 3 , FIG. 3 is a schematic structural diagram of another pixel lamp provided by an embodiment of the present invention, wherein, the light-emitting unit 102 includes a light-emitting diode 301 and a resistor 302 , and the anode of the light-emitting diode 301 and the resistor 302 are connected to each other. One end is electrically connected, the second end of the resistor 302 is electrically connected to the power supply layer of the PCB board, and the cathode of the light emitting diode 301 is electrically connected to the ground layer.

Specifically, the power supply VCC in FIG. 3 can be understood as the power supply layer of the PCB board. Correspondingly, the grounding can be understood as being electrically connected to the grounding layer. The resistor 302 is used to limit the current to prevent the light-emitting diode 301 from being burned due to excessive current. Bad. The area surrounded by the four cutting lines 104 surrounding the LED 301 and the resistor 302 can be understood as a light-emitting unit 102 .

Therefore, when the pixel lamp is cut into different shapes along the cutting line 104, the light is emitted. The internal circuit structure of the unit 102 will not be damaged, and the tailorability of the pixel lamp can be realized.

In the technical solution of this embodiment, by setting the specific circuit structure of the light-emitting unit, the light-emitting unit after cutting can still realize the lighting or display function. At the same time, the series structure of the resistor and the light-emitting diode is adopted, the circuit structure is simple, and the cost of the pixel lamp is reduced. .

In the area P, the pixel lamp is fixed on the surface of the object using tools such as screws, so that the pixel lamp is more firmly connected to the surface of the object that needs to emit light. It can be understood that, in order to avoid short circuit between the power supply layer and the grounding layer of the PCB board 101 when using metal connection materials such as screws, the arrangement of the power supply layer and the grounding layer may also avoid the fixed connection area.
