FLDL-i74x27-UV24-365-255This lighting is used, among other things, in the paper industry for material differentiation in material mixtures.
Two photophysical processes-fluorescence and phosphorescence-are used to detect the respective proportions in a material mixture.
Light-emitting diodes with short-wave UVC light (wavelength λ= 255nm) but also LEDs with long-wave UVA light (wavelength λ= 365nm) excite materials that are in a dark environment by the high-energy light. After the LED's are turned off, fluorescent materials quickly release the energy, making the material immediately invisible. Phosphorescent materials, however, release the energy more slowly. This results in an afterglow.
Depending on the material, this can last from a few seconds to several hours (e.g. emergency exit sign).
In order to be able to illuminate the material mixtures always at the same angle, a 2-in-1 lighting from Falcon is the ideal solution.

Falcon introduces the F2DL, a new series of Barligths.Highest quality at the best price!
The new bar light F2DL is not only affordable, but offers many other advantages:
A lens array, which is inserted above the SMD LEDS's, bundles the emitting light from αLight= 120° to αLightLens=60°.
This reduction of the light angle results in a focused light beam, which guarantees a higher brightness at the test part.
Above this lens array is another rail through which it is possible to insert a diffuser and a polarizing filter or a light control film. Deformation or deflection of the diffuser disk, which can occur due to the thermal radiation of the LEDs, is prevented by the continuous rail contact.
