90520D LED Headlight with AC/DC Power Only

Overview 1

The Integra LED Surgical Headlight System is a self-contained headlight system that can be operated using either battery or direct power supply. Using a battery pack gives the surgeon complete mobility allowing unrestricted movement in and around the operating suite. The direct power supply option can be used as a primary power source for unlimited operating time, or as a back-up to the battery system.

2

The AC/DC Power Only model comes equipped with these components: 2

• LED Headlight with Cable • AC Mains Power Cord

The Integra LED Surgical Headlight System utilizes an LED light source with an active cooling system. A thermostaticallycontrolled cooling fan draws air at a very low flow rate through ports on the side and back of the headlight module, quietly cooling the LED. The air is drawn through a system of ducts and is gently exhausted behind the surgeon. The major components of the Headlight itself are shown in Figure 1 and described below.

• 30W Power Supply • 20’ DC Power Extension Cord

Detach and firmly seat to assure complete connection.

Cleaning

Brightness of spot decreases during use.

Temperature of LED may have increased due to blockage of airflow.

Turn off the headlight, check and remove any obstructions from the headlight module and controller fan vents.a

Brightness of spot is diminished and / or the spot appears fuzzy.

Lens may be contaminated.

Clean lens with 70% Isopropyl Alcohol.

Fully charged battery operates headlight for less than 2 hours.

Battery may be losing charge capacity. Replace battery.

Cooling fan is making a whirring or clicking sound.

Fan may have been damaged after dropping headlight.

1. Unplug the unit prior to cleaning. 2. Wipe the surfaces of the Headlight and cables with a cloth slightly dampened with a mild detergent, 70% isopropyl alcohol, mild soap and water or solution of 10% bleach and water. Use only 70% isopropyl alcohol to clean the Headlight lens. Excess solution entering the headlight assembly could damage internal components. Use caution to ensure cloth is not saturated with solution. 3. Do not operate the system until the Headlight is thoroughly dry.

Return to Integra for service.

The operating temperature of the LED is continuously monitored and the fan speed is adjusted to maintain proper LED operating temperatures. In the event of a malfunction in the cooling system or blockage of airflow, the power in the LED will be reduced to the low setting. If the temperature of the LED continues to rise, the intensity of the headlight will default to a setting less than the low setting of the headlight. This serves to communicate the overheating condition while maintaining some level of illumination until an alternate light source can be employed

NOTE 1. At 80 MHz and 800 MHz, the higher frequency range applies. NOTE 2. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the system under test is used exceeds the applicable RF compliance level above, the system under test should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the system under test.
