Calculating the length d of the (n + 1) th luminairen+1＝D-(d1+d2+……+dn)-(n-1)*dLamp gap-2*dSpacerCutting to obtain a lamp with a corresponding length as an n +1 th lamp;
from one end of the vehicle body to the other end of the vehicle body according to the first distance d between two adjacent lampsLamp gapAnd a second distance d between the end lamp and the end wall of the vehicle bodySpacerThe first n lamps are installed, the (n + 1) th lamp serves as the last lamp, the situation that the residual length size is measured after the first n lamps are installed is avoided, then the last lamp is cut is avoided, time for installing the lamps is saved, lamp installation efficiency is improved, and construction progress of the whole vehicle is improved.
It is easily understood that the vehicle body measurement length D may be measured by a laser range finder.
Example four
A rail vehicle lamp installation method comprises the following steps:
acquiring the longitudinal length of a vehicle body of the railway vehicle, namely the measured length D of the vehicle body;
acquiring a first distance between two adjacent lamps according to the longitudinal length of a railway vehicle body, the total length of the lamps in the lamp strip and a second distance between the end lamp and a vehicle body end wall;

Wherein, the first distance d between two adjacent lampsLamp gapThe calculation is made according to the following formula:
dlamp gap＝[D-(n+1)d-2*dSpacer]/n
Wherein: the lengths of all n lamps d in the lamp strip are the same, and n +1 is the number of all the lamps in the lamp strip.
