ABSTRACT:
The reflector of the spotlight has two assembly lugs directly fitted thereto and connected to an intermediate assembly part which includes means for fixing to a support. Said intermediate assembly part and said lugs are shaped to ensure that two mutually perpendicular planes defined relative to said reflector coincide with corresponding ones of two mutually perpendicular planes defined relative to said intermediate assembly part, regardless of relative thermal expansions which may take place in the reflector and the intermediate part under normal conditions of use. Relative to the reflector said planes comprise a first plane including the optical axis and a second plane perpendicular to said first plane and parallel to the optical axis. Such an assembly reduces the effect of thermal expansion on the adjustment of the direction in which the optical axis points.
