1. A method of assembling a lighting device comprising a tubular body and a solid state lighting assembly in said tubular body, said assembly comprising a flexible optical film and a plurality of solid state lighting elements on a carrier, said carrier contacting said optical film, the method comprising:
providing a feeding apparatus comprising a first wheel comprising a pair of first rims delimiting a first main body having a concave surface profile and a second wheel comprising a pair of second rims delimiting a second main body, wherein the first wheel cooperates with the second wheel such that the first rims cooperate with the second main body, and wherein the first rims are separated from the second rims by a spacing, said apparatus further comprising an outlet including a feeding funnel for engaging with the tubular body;
placing said tubular body on said feeding funnel;
feeding an end portion of the solid state lighting assembly into the feeding apparatus such that a first part of the end portion including said carrier is located in between the first main body and the second main body and a pair of second parts of the end portion extending from either end of the first part are located in said spacing such that said second parts are each shaped into an arcuate portion for lining a part of the inner surface of the tubular body by a respective one of said first rims; and
rotating said first and second wheels such that the solid state assembly is shaped and fed into the tubular body through the feeding funnel.
