Introduction
The Prima™ Surgical Light is intended for use in both surgical and non-
surgical applications to provide illumination of the surgical field or patient (see
figure 1-3 on page 1-6). It delivers color-correct, shadow-free, uninterruptable
illumination through fingertip controls.
Figure 1-3. Prima™ Surgical Light
The lighthead assemblies house the lamps (one primary and one secondary) as
well as the Hand Control. The secondary lamp is a back-up to the primary lamp
should it fail. The lighthead assemblies pivot on yokes. The yokes mount to the
counterbalance arm assemblies which connect to the vertical tubes. The
vertical tubes attach to the suspension arm assemblies which connect to the
ceiling mount.
The Hand Control places all user controls within the sterile field. On/off, light
intensity, light pattern, and light head position are all controlled using the Hand
Control. Lamp intensity is indicated by LEDs located on the side of the Hand
Control housing.

The lighthead/yoke assemblies rotate 360°. The interior of the lighthead
assemblies is designed to optimize the reflex angle of the light. This reduces
shadowing and delivers cleanly defined color-correct light.
The counterbalance arm assemblies rotate 15° above horizontal and 90° below
horizontal at the clevis. The clevis assembly provides a brake to prevent “free
wheeling” of the counterbalance arm and to provide “touch type motion
control.”
The suspension arm assemblies rotate 360°. They vary in length to permit
passing without interference. The vertical tubes rotate 360° and are custom-
sized to a specific ceiling height ensuring adequate head clearance.
The flush-mounted, wall-control panel provides an additional on/off and
intensity control as well as an indicator to relamp damaged bulbs. Spare bulbs
can also be stored in the upper housing compartment. An individual control
box supplies 23V AC and 9V DC power to each Prima™ Surgical Light and
9V DC power to each wall control panel P.C. board.
