The pins engage in holes in the gallery or in members movable in an annular groove in the gallery and springs on the pins keep the carrier in central position. To detach the carrier it is moved laterally to disengage one of the pins and then tilted whereupon the other pin can be disengaged. The leaf springs 20 are located at 90 degrees to the pivot axis of the carrier. and are secured to either the gallery or the carrier. The gallery may comprise an inner ring in which the carrier tilts and and outer ring secured to the ceiling, the inner ring being rotatable in the outerring. The upper part of the carrier above the ceiling supports a lamp and comprises a U-shaped bracket 10 to which the lamp is secured and which is pivoted to arms 9 upstanding from the lower part of the carrier. Coaxial cylindrical louvres 22 are mounted on the lower part of the carrier which may also have colour filters or lenses.
