| Title: |
Lighting Fixture Zoom Device, and Lighting Fixture Comprising Said Zoom Device |
| Abstract: |
A zoom device for a lighting fixture has a first lens assembly of
positive refractive power; a second lens assembly of negative refractive
power; and a third lens assembly of positive refractive power. The first
lens assembly, second lens assembly, and third lens assembly are aligned
along a longitudinal axis coincident with the axis of a light beam
emitted by a light source of the lighting fixture, and are characterized
by respective focal lengths, which are such as to effectively adjust the
size of the images projected by the lighting fixture, while at the same
time maintaining compactness of the zoom device.
