Automatically Adjusting The Lamp Position Using Lamploc - Christie Solaria CP2220 User Manual

Section 3: Operation

Automatically Adjusting the Lamp Position Using LampLOC™

For best results in all
installations, perform a
LampLOC™ adjustment. This
activates a set of motors and
sensors in the projector to
precisely position the lamp for
optimized performance and
brightness, while utilizing
filtering to eliminate signs of
lamp flicker. Once aligned, this
LampLOC™ setting can be
considered fairly stable for the
life of the lamp.
To automatically adjust
LampLOC™, do the following:
1. Navigate to the Advanced
Setup: LampLOC™
Setup window. (Figure 3-
65)
2. Click the Do Auto button.
3. Let a few minutes pass to
allow the LampLOC™ mechanism to establish the best lamp position and optimize the light output. You
will see 100% displayed on the screen when the operation is complete. TIP: You can improve on-screen
uniformity after running LampLOC™ by manually adjusting the z-axis motor. However, brightness
efficiency will be decreased by a very small amount when this is done.

Manually Adjusting the Lamp Position
The individual XYZ lamp position buttons, each of which moves the lamp in one axis only, are provided as a
reassuring back-up should the Do Auto button fail, or if you feel the manual, operator-assisted lamp
optimization results in greater output or improved brightness uniformity. Either measure your results with a
light meter at the lens and screen or simply watch the light output gauge in the Intensity column of the
Advanced Setup: LampLOC™ Setup window. NOTE: These buttons may attain a slightly higher peak than
the Do Auto button, but the peak may not be centered on the lamp curve and lamp performance may not be
optimized. Also, the Do Auto button utilizes filtering to eliminate the effects of any lamp flicker. In general, use
the individual buttons only when you feel it is unavoidable.
Obtain peak readings on a light meter centered in front of the lens and then at the center of the screen. For each
button, continue in one direction and then back up or reverse when the reading begins to decrease. NOTES: 1)
This is an optional procedure—use the light output gauge in the Advanced Setup: LampLOC™ Setup window if
preferred. 2) After performing LampLOC™ (Do Auto), brightness uniformity may also be improved on some
lamps by manually adjusting the z-axis motor control. In some instances, this may cause a reduction in overall
brightness.
1. Display a 100% white internal test pattern.
2. Use a tripod to center the light meter with the lens. The distance from the lens does not matter. You may
need an attenuator or wish to construct an internal foil aperture first.
