An angle adjustment and rotation system comprising a first element attachable to a luminaire stand, and a second element configured to be attachable to a luminaire head, the first element and second element comprising substantially complementary shapes, and an attaching element configured to have a first state in which it tightly attaches the first element to the second element and a second state in which it movably attaches the first element to the second element. In the second state, the attaching element enables a rotation over substantially 180 degrees of the second element with respect to the first element. A method of controlling the orientation of a luminaire head connected to a luminaire stand is also proposed, preferably using the proposed system.

A lighting fixture includes a light source holder, a pair of position adjustors, and an outer shell. The light source holder holds a light source. The position adjustors are arranged to face each other and interpose the light source holder between themselves and supports the light source holder to allow the light source holder to rotate around a first virtual axis defined as a virtual axis passing through the position adjustors. The outer shell has an opening in which the light source holder and the position adjustors are arranged and supports the position adjustors to allow the position adjustors to rotate around a second virtual axis defined by a normal to an opening plane of the opening. The first virtual axis intersects with the second virtual axis and is located either within or behind the opening plane.
