Abstract:
The invention concerns a product (1) and a procedure for the manufacture of a product (1) for the further transport of an incoming light, comprising at least one layer (3) of material substance (2) in which a number of optical fibre threads (6) are incorporated, each optical fibre thread (6) comprising an input surface (7) for the interception of the incoming light, and an output surface (8) for emission of the incoming light from the input surface (7), in that said surfaces (7, 8) are connected by a body (9) through which body (9) the incoming light is conducted from the input surface (7) to the output surface (8), said output surface (8) and input surface (7) lying substantially free of the layer (3) of the material substance, said layer (3) comprising a first surface (4) oriented towards the incoming light. The input surface (7) and the output surface (8) are both able to intercept and emit light and are extending from the first surface (4), said light including both visible light and UV and infrared light. There is hereby achieved a product and a procedure for the manufacture of said product which reflects an incoming light in the same direction as that in which it has been intercepted. The product is thus suitable for road stripes, signs, clothing, algae growth, airports, tele- and data-communications etc.
Abstract:
An optical system and a lens for railway signals are provided. The optical system comprises a frontal (1b) and a rear (1a) body section, wherein the rear body section (1a) comprises a light source (2) comprising one or more light-emitting diodes, a rear lens (4), and a light-absorbing structure (8) surrounding the rear lens (4). The frontal body section (lb) comprises a converging frontal lens arrangement (11), and a casing connecting the frontal lens arrangement (11) to the rear body section (la). The rear lens (4) is configured to pass light collected from the light source (2) towards the frontal lens arrangement (11). The rear lens (4) comprises a cut-out (15) under a substantially horizontal line below its center, and the light-absorbing structure (8) surrounding the rear lens (4) covers the cut-out of the rear lens (4), and is configured to absorb light coming from the direction of the frontal lens arrangement (11).

Abstract:
Road-side reflector network (Reflective Marker Network), established through optically coupling of individual roadside markers / reflectors. Each individual roadside marker acts as a light collector and reflector; partly reflecting the light and partly transmitting the light through optical coupling (e.g. optical fibres) to other roadside markers. The proportion of transmitted light can be anything from 0 to 100% of the incident light, the proportion of reflected light being the remainder of the total incident light. Any coupling distribution is possible, thereby theoretically extending the distance over which the roadside markers are lit-up to infinity, and far beyond the reach of conventional, non- coupled road side markers, where the distance is limited to the range of a car's head light.
Abstract:
The invention concerns a method for embedding in a road pavement claddings designed to house optical fibre cables, characterised in that it consists in: a) levelling at least part of the running surface (7) of the road and optionally part of the base layer (8) of said road, to produce a continuous slot (4); b) laying flat the claddings (5) at the base (6) of said groove (4), at least some of the claddings being non-contiguous to create a space (e) between the claddings (5); refilling at least partly the groove (4) with concrete (14) to cover the claddings (5); d) providing above said concrete (14) a running surface layer (11, 12).

Abstract:
A road marking unit (1) according to the invention comprises a house (10) with a light transmissive window (20). In the house (10) is arranged an electro-optic switch (30). In an activated state of the road marking unit (1) the electro-optic switch (30) achieves that light is reflected from the window (20) back to the window (20). In a de-activated state of the road marking unit (1) the electro-optic switch (30) achieves that light from the window (20) is absorbed. The road marking unit (1) of the invention has the advantage that it can also in bright environmental light be switched between visible and invisible.
