| Title: |
Luminaire |
| Abstract: |
A luminaire consisting of a Fresnel spot light combined with a studio
flood-light arranged back-to-back so that when the spot-light is in use
and the flood-light is inactive, displacement of the lamp carriage of the
spot-light can be accommodated by passing it through an opening in the
main reflector of the inactive flood-light, or by displacing the main
reflector of the flood-light, thus saving space.
