Abstract
A surgical lighthead includes a reflector, a lens coupled to the reflector, and a handle located adjacent the lens. The handle defines an air passage to facilitate installation of a shield over the handle. A lamp assembly includes a support and at least one bulb located on the support between the reflector and the lens. Tubes are mounted in an interior region of the lighthead between the reflector and the lens, and rods are configured to engage the support. Each rod extends through the support and into a corresponding tube. The rods include at least one threaded portion configured to secure the lamp assembly within the interior region. The rods are slidable relative to the tubes upon disengagement of the threaded portions of the rods to permit the lamp assembly to move out of the interior region of the lighthead. The rods include stops to prevent separation of the lamp assembly from the lighthead. A controller turns the bulb on and off and adjusts the intensity level of light emitted from the bulb. Spaced apart first and second displays are coupled to the controller. Each displays an indication of the intensity level of the bulb.
