| Title: |
Shutter Lock |
| Abstract: |
The present invention relates to a lighting apparatus or a shutter
assembly for a lighting apparatus comprising: a light path for passage of
light emanating from a lamp, at least one shutter plate 130-133 moveable
into a position external to or at least partially across the light path,
and a rotatable shutter lock 180 being rotatable to directly or
indirectly generate a friction force on the shutter plate 130-133,
wherein the friction force generated on the shutter plate 130-133 is
dependent on the rotational position of the shutter lock 180 and in at
least one rotational position there is sufficient frictional force to
retain the shutter plate 130-133 in the position external to or across
the light path.
