Abstract

The described systems 200 provides a simplified slide system for longitudinal movement of optical light modulators 102 for automated luminaires 12 employing expansion and contractions slots 125, 126 which allow for precise smooth movement over a range of temperatures.

Claims

1. An automated luminaire with a light beam axis with light modulators mounted on a slide for positioning the light modulator along the light beam axis where the slide further comprises:

a carrier for the light modulator;

a slide rail for constraining the movement of the carrier; and

an interface between the carrier and rail employing a plurality of slots in the interface.

2. The automated luminaire of claim 1 a plurality of slots run vertically on the interface forming a plurality of fingers encircling the slide rails.

3. The automated luminaire of claim 2 at least on slot runs along the length of the carrier interface along the slide rail.

4. The automated luminaire of claim 2 where slot(s) separate individual finger from completely encircling the slide rail.

5. The automated luminaire of claim 2 where slide rails cross section is round.

6. The automated luminaire of claim 2 where the slide rail cross section is not round.

7. The automated luminaire of claim 1 where carrier is formed of a self-lubricating plastic.

8. The automated luminaire of claim 1 where the slide includes:

a plurality of slide rails; and

a plurality of slide rail interfaces.

9. The automated luminaire of claim 1 where the slide includes a plurality of carriers for a plurality of light modulators.

11. The automated luminaire of claim 2 where slide rails cross section is round.

12. The automated luminaire of claim 2 where the slide rail cross section is not round.

13. The automated luminaire of claim 1 where carrier is formed of a self-lubricating plastic.

14. The automated luminaire of claim 1 where the slide includes:

a plurality of slide rails; and

a plurality of slide rail interfaces.

15. The automated luminaire of claim 1 where the slide includes a plurality of carriers for a plurality of light modulators.

10. An automated luminaire with a light beam axis with light modulators mounted on a slide for positioning the light modulator along the light beam axis where the slide further comprises:

a carrier for the light modulator;

a slide rail for constraining the movement of the carrier; and

an interface between the carrier and slide rail comprising of a multitude of closely spaced fingers gripping the slide rail.
