Abstract
Lighting apparatus includes an effect wheel which is mounted on a rotation mechanism. The rotation mechanism is mounted on a mechanism which moves the effect wheel from a position outside of the light path to a position in which the effect wheel intersects the light path to provide a continuous wheel effect. The translation mechanism can move the effect wheel between positions in which the effect wheel crosses the light path in a horizontal direction and in a vertical direction, respectively. The apparatus allows a continuous wheel effect to be added to a multi-purpose luminaire and also allows the direction of travel of the continuous wheel effect across the illuminated field to be continuously varied.
Claims2
A removable optical component for a lighting fixture comprising:
- an optical portion adapted to alter the visual appearance of a light beam passing there through;
- a magnetic portion arranged to attach the optical component to a surface of a lighting fixture by magnetic attraction;
- and at least one locating formation configured to engage with a complementary locating formation on said lighting fixture to locate the optical component in position on said fixture.
