Abstract: A LED light device has a number of LED's, a multiple optical assembly defined by a number of modular units; each modular unit has a total internal reflection lens associated with a LED; and the modular units are connected to one another so as the lenses have respective distinct optical reflecting surfaces.

Abstract: A transmitted light fluorescence microscope, presents a mount, a lighting assembly and a condenser interposed between the lighting assembly and the mount; the lighting assembly includes at least one LED which emits in a spectral band adapted to excite the fluorescence of the sample to be analyzed and is arranged below the mount to light the sample from underneath; an emission filter is interposed between the sample-holder mount and an eyepiece of the microscope for filtering the fluorescent emission of the sample.

Abstract: A luminescence analysis apparatus, in particular for fluorescence microscopy, has a lighting assembly having a lighting unit which includes a preassembled module housed inside a housing; the module is defined by a LED mounted on a plate, and by an optical collimating element connected integrally to the LED and located in close proximity to the LED; the optical element is a catadioptric collimator made of transparent plastic material and designed to internally convey and transmit the light emitted by the LED, so as to generate a substantially parallel beam of light rays which is directed onto a luminesce sample for analysis.
