Safety
concept Intended use: The Leica L5 FL cold-light source is intended for use in industry and laboratories. Cold-light sources are used for intensive illumination of all types of objects. The infrared portions of the lamp radiation are filtered out. Visible light of high intensity is guided to the object through flexible or self-supporting movable fiber-optic light guides.
Page 5
Avoid looking directly into the open tensioning sleeve or the fiber-optics output when the light source is activated. The Leica L5 FL emits visible light of high intensity. Since light-absorbing materials have the physical characteristic of converting incident light into heat, damages may occur to heat-sensitive or inflammable light-absorbing materials.

The two levers must also be pressed down when the new bulb is inserted. Insert the lamp housing to the stop (you should hear it engage). Switch on the light source. Fig. 3 2 sockets for halogen lamp Leica L5 FL...
The instrument is switched off. Position: The instrument is switched on. The Leica L5 FL is equipped with a soft start to protect the halogen lamp that reduces an otherwi- se high starting current. In addition, an electronic stabilization of the lamp voltage ensures stable luminous efficiency, independent of supply voltage fluctuations.
Operation Luminous intensity The Leica L5 FL is equipped with two independent setting luminous intensity settings. The continuous electronic adjustment allows optimizing the lamp service life. The exact adjustment of the required brightness allows you to achieve the highest possible service life of your halogen lamp.

After overstepping the barrier at position 5, a lamp symbol (20) appears on the LCD display that flashes for a few seconds. It serves as a maximum light indicator and indicates that the expected bulb service life is reduced compared to position 5. Leica L5 FL...

To adjust the light spot, the screw must be untightened first. The focusing lens can now be moved back and forth. This, in turn, increases or decreases the light spot and the user can determine the size and intensity of the light spot. Leica L5 FL...
Maintenance The Leica L5 FL is maintenance-free. A disinfection of the light source for applications in the medical sector is not required and therefore, not planned. Use a soft dry cloth or commercial plastic clean- sing wipes to clean the outside of the instrument.
