Use

5.1

Operating principle

The ENDOLIGHT LED 1.3 light is used for illuminating the operating field in the patient's body. For this purpose the light is transmitted from the light source via a light cable to the instrument tip. In conjunction with an interactive (i.e. dialog-capable) camera controller and activated shutter function (ELC ON), with varying object distance constant brightness is automatically adjusted. The color temperature of the LED light source is approx. 6500 K. This is important for true color rendering in particular when recording videos. Optimum ventilation and adherence to the operating notes and instruc­ tions allows an LED service life of approx. 30000 h.

5.2

Controls and modes

5.2.1

"Dialog" function

The dialog function allows communication between the light projector and the interactive camera controller. The dialog function uses the fast ELC control of the camera controller to adapt image brightness while the light projector is equipped with automa­ tic brightness control. Automatic brightness control "ELC" of the camera controller must be swit­ ched on. The brightness control on the light projector is automatically controlled via the camera controller, manual brightness selection on the light projector is not possible. The above requires a connection between the devices using a CAN BUS connection cable (see connection diagram in section 1).

.

14

NOTE! We recommend working with the activated dialog function at all times.

GA-A 281

5.2.2

"Safe start" function

The safe start function is an additional safety query for switching on the LED with the “Light” button. ' The safety query must be confirmed with “OK” in order to switch on the LED. If this safe start function is deactivated the “Light” button switches on the LED immediately (the light cable needs to be connected). ' In the case of a device failure due to an interrupted power supply bet­ ween 5 seconds and 30 seconds the safe start function is automatically activated. Z The safe start function can be switched on and off in the Device para­ meters - Service - General service - Device info menu for the selected user-specific profile. ' In the standard profile, the safe start function cannot be activated.

5.2.3

Temperature protection circuit Blocked vent slots in the device rear panel or insufficient air circulation can cause increased temperatures inside the device. A temperature protection circuit monitors the device temperature. In the case of overtemperature the LED brightness is in a first stage conti­ nuously reduced and then shut down if the temperature increases any further in order to avoid additional damage. The fan speed is controlled as a function of temperature.
