Abstract

Improvements are disclosed to lighting fixtures adjusted in beam direction during use, both manually and remotely by an operator. The head of the manual fixture is mounted rotatably between two standards, which are attached to a base, such that the attachments can be moved vertically along the standards to adjust the distance between the head and base. The remote fixture uses a two-axis mirror for beam direction and at least one additional axis of adjustment. Improvements to power and data distribution and pre-rig truss are disclosed.

Claims

1. - In a lighting fixture, said fixture comprising:

a light source, said light source producing light,

an optical system, said optical system forming said light into a beam, said beam having an angular beam-spread

mechanisms for altering said beams-pread

a housing, said light source, said optical system, and said mechanisms being contained in said housing,

first and second standards for supporting said housing, at least during use,

first and second attachments, said first and said second attachments supporting said housing from said first and said second standards so as to permit rotation of said housing around a substantially horizontal first axis,

a base, said base supporting said housing and said standards, at least during said use, said base permitting rotation of said head around a substantially vertical second axis,

the improvement wherein the distance between said base and said housing can be changed by displacing said first and said second attachments vertically along said standards.
