Surgical light parts and what each one does

The light head and the LED modules

The light head, often called the dome, houses the light sources, optics, electronics and controls. In an LED light the sources are modules of many small emitters. The number of LEDs is a datasheet item: the Lojer Q-Flow 700 mm heads carry 90 LEDs and the 560 mm heads 69.

The housing protects the electronics and sets the cleaning behaviour. The SIMEON Sim.LED 8000 uses an IP54 housing of aluminium and real glass with Anti.BAC coating, and the Q-Flow 1 and 2 examination heads are splash-proof to IP44. A seamless closed surface without joints simplifies disinfection.

Reflectors, optics and shadow management

Reflectors and lenses shape the beam so that light arrives from many directions and a single hand or head does not cast a deep shadow. SIMEON uses patented reflector technology, and the HighLine and BusinessLine heads add RSRS, the Reflector Shadow Resolution System. The 8000 adds sensor-based active shadow management.

The cover glass is both optical and mechanical protection. Scratches or hazing lower illuminance and make cleaning harder, so check glass condition during inspection.

Handle, controls and control panel

The sterile handle is the point where the surgeon positions the light. In SIMEON lights this is the my.GRIP handle, which can be personalised, and the Q-Flow examination lights have a detachable, sterilizable handle. Alternatively, a sterile disposable cover is used, see surgical light handle covers.

The controls on the head, often cardanic, allow the user to set brightness and colour temperature. A wall-mounted touch panel is available for the SIMEON Sim.LED 8000. Intelligent versions of the Q-Flow family add a sterile user interface. Control electronics also hold the presets, for example my.LED with up to 99 user profiles on the 8000.

Spring arm, central axis and ceiling plate

The light head sits on a spring arm that balances it so that it stays where it is placed. The arm turns around the central axis, which is fixed to the ceiling plate. Brakes hold the position, and the cable runs through the arm to the head. For the SIMEON spring arms the range of movement is +45° to -75°.

Several arms can share a central axis, carrying lights, cameras and monitors. SIMEON Sim.FLEX takes up to four arms on one axis and can be extended after installation. A full explanation is in our guide to suspension systems. The structure above the ceiling must carry the total load, which an engineer must confirm.

Cameras, monitor holders and accessories

Many lights accept a camera in the head or on a separate arm, and a monitor holder. Lojer Q-Flow Vision and Intelligent versions offer a camera option, including wireless 4K, and the SIMEON lights are camera-ready with Sim.CAM and Sim.SCREEN.

• Wear parts: sterile handles or covers, filters in some designs, brake elements, seals.
• Parts that need inspection: cables in the arm, ceiling plate screws, glass cover, locking mechanism.
• Parts that need qualified service: LED modules, drivers, control electronics.

Questions to ask about spares and service

Ask which parts the manufacturer sells separately, how long they are guaranteed available, whether modules can be replaced without changing the whole head and who in the UAE can fit them. Your service plan should include annual checks of balance, brakes and electrical safety. Beckfinity supplies manufacturer documentation and parts information for the SIMEON and Lojer ranges, and you can request a quote or a technical consultation from our specialists.
