It is understood that the electrically related parameters of the lighting tube include the total loop power, loss factor, light source power factor, line power factor, core wire cross-sectional area and/or loop length of the lighting tube. Wherein the total loop power represents the total power consumed by the lighting tube, the loss coefficient represents the loss condition of the lighting tube under the condition of power on, and the power factor of the light source refers to the cosine of the phase difference between voltage and current when the light source is powered on in the circuit of the lighting tube. The lower the power factor of the light source, the larger the reactive power of the lighting tube loop used for alternating magnetic field conversion, and the lower the utilization rate of the light source in the lighting tube loop, the larger the power supply loss of the lighting tube loop. Similarly, the line power factor is the power factor of the lighting tube in the lighting tube loop. The core wire cross-sectional area is the area of the cross-section perpendicular to the axial direction of the lighting tube of the core wire wrapped by the lighting tube. The loop length is the total length of the conduits arranged in the lighting conduit loop.
Step S21: the loop voltage drop of the lighting tube is determined to be less than or equal to the allowable voltage offset value based on the electrical related parameter.
Referring to fig. 2, fig. 2 is a flowchart of a step of determining that a loop voltage drop of an illumination tube is less than or equal to an allowable voltage offset value according to an embodiment of the present application. Optionally, step S21 includes the sub-steps of:

Step S213: the loop voltage drop is calculated based on the loop current, the line power factor, the core cross-sectional area, and the loop length.
It is understood that the loop voltage drop represents a voltage variation value in the loop of the lighting tube, and as an embodiment, the loop voltage drop may be calculated by a loop voltage drop calculation formula, where the loop voltage drop calculation formula includes:
where r represents the total resistance of the light sources of the lighting tube loop,indicating the rated power factor of a nonlinear load, x indicating the inductance of the light source of the lighting tube loop, U N Indicating the nominal voltage of the circuit of the lighting tube, I C The loop current is represented by L, and the loop length is represented by L, wherein r and x are obtained by looking up a table in the industrial and civil power supply and distribution design manual based on the core wire cross-sectional area.
Step S214: the loop drop is determined to be less than or equal to the allowable voltage offset value.
It can be understood that the loop voltage drop calculated in step S213 is compared with the allowable voltage offset value, and when the loop voltage drop is less than or equal to the allowable voltage offset value, the minimum pipe diameter is determined. When the loop voltage drop is greater than the allowable voltage offset value, modifying the electrical related parameters of the lighting tube including the total loop power, loss factor, light source power factor, line power factor, core wire cross-sectional area and/or loop length of the lighting tube, re-calculating the loop load according to step S211, the loop current according to step S212, and the loop voltage drop according to step S213 until the loop voltage drop calculated according to step S213 is less than or equal to the allowable voltage offset value.

The allowable voltage offset value in the lighting tube is set according to the specifics of the light source in the lighting tube loop.
