Abstract: Device to detect at least an analyte, comprising a transparent substrate (2), having a first surface (3) with which a light source (7) is associated, and a second surface (4) on which a plurality of biological protein probes (12) are disposed, a layer (6) of polymer being interposed between said second surface (4) and said biological protein probes (12). A marker (fluorophore) is associated with said analyte, having determinate characteristics of fluorescence and/or phosphorescence correlated to the emission wavelength of the light source (7). Said light source (7) is suitable to emit a light radiation in a range of wavelengths equal to 400-550 nm, inside which range the absorption peak of said marker (fluorophore) used is comprised. The value of the distance (“s”) between the wavelength corresponding to the absorption peak of the marker (fluorophore) and the wavelength corresponding to the emission peak of fluorescence (phosphorescence) is comprised between 25 and 150 nm.

Abstract: A light device, for example in the form of a light panel for road signals or in the form of a motor-vehicle light, comprises an array of light sources, such as LEDs or the like. Associated to each light source is an optical system consisting of a refractive lens of a plane-convex type having a plane face facing the light source, in which a diffuser of a refractive or diffractive micro-optical type is incorporated.

Abstract: Lighting device and method to make it. The device comprises a light source (11) including a positive electrode (14) and a negative electrode (13) between which a luminescent layer (16, 17) is located. On the outer side of the multi-layer structure there is a substrate (20) which diffuses the light generated by the luminescent layer (16, 17). A lenticular optical element (21) is associated with a face of the substrate (20) and is obtained by means of molding in a single piece in the substrate (20). The optical element (21) consists of micro-lenses (22) each one cooperating with a relative point of light emission (19) to direct and shape the relative ray of light emitted.
