Abstract:
The invention relates to a transparent substrate including at the surface thereof a network of lines including at least 200 light emitting patterns, said patterns being separated by domains having a refraction index different from that of the patterns, the distance between the baric centres of adjacent patterns varying in a non-monotonous manner from one edge of the network to the other so that for each group of 50 successive patterns, the distance between the baric centres of patterns adjacent to said group is at least one times larger and at least one times lower than the average distance dm of the distances d between the baric centres of adjacent patterns in said group, dm ranging from 75 to 200 µm. The substrate is transparent under direct vision and redirects light by scattering it without iridescence in daylighting applications.
Abstract:
The invention relates to a lighting structure (100) comprising a planar guide (1) for visible or ultraviolet radiation provided with an edge (13a) and two substantially parallel main faces (11, 12), wherein at least one of them extracts at least one part of said radiation, at least one quasi point radiation source (2), which is embodied in the form of a light-emitting diode coupled to the guide for transmitting the radiation thereinside, has at least one main radiation-transmitting direction and is arranged in such a way that said main radiation-transmitting direction after being refracted on the guide has an incidence (formula I) with respect to at least the first intersected main face (12) greater than the total reflecting incidence (formula II) given by a relation (formula III), wherein n1 is defined as the guide refractive optical index.
Abstract:
The invention relates to windscreen-type laminated glass panel for a motor vehicle or a glass panel for a building with a HUD component, comprising the assembly of at least two transparent sheets of inorganic glass or a PC-type durable organic material, which are interconnected by a spacer made from a thermoformable material or by multi-layer sheets including one such spacer. The glass panel is characterised in that it also includes, on at least part of the structure thereof, a thin film having a thickness of less than 20 microns and containing at least one fluorescent material in the form of particles having a size that is adjusted so that the light transmission of the glass panel remains above 70%, said fluorescent material re-emitting a radiation in the visible range when subjected to an incident excitation light wave in the ultraviolet range. The glass panel is also characterised in that, during assembly, the above-mentioned film is positioned between the thermoformable spacer and the passenger compartment of the vehicle or the interior of the building.
Abstract:
A film has an inner and an outer surface. The film includes a first layer forming the outer surface and including fluoropolymer. The film further includes a second layer disposed away from the outer surface comprising a polymer. The polymer can have a storage modulus at 65oC of at least 5 MPa. The film has a plurality of surface features forming the outer surface and extending into the first and second layers. The surface features have a mean slope of at least 15o. The film can be applied as a protective film overlying an active component of a photovoltaic device.
