Title (EN) LIGHT EMISSIVE SIGNAGE DEVICES BASED ON LIGHTWAVE COUPLING
(FR) DISPOSITIFS DE SIGNALISATION PHOTOLUMINESCENTS METTANT EN ŒUVRE UN COUPLAGE D'ONDES LUMINEUSES
Abstract: front page image
(EN)A signage device (180, 180', 190, 199, 200, 200', 208, 209, 242a-f, 250, 260, 270, 280) comprising one or more light sources (185), a waveguide (184, 204, 210, 226, 230, 251, 290, 300, 402) or arrangement of waveguides (184a,b, 204a,b, 262a-c, 271 a-c, 284a-c) and photoluminescent features (182, 182a,b, 200a,b, 254, 266a-c, 291, 301) coupled thereto. In one embodiment, a waveguide (184, 184a,b, 204, 204a,b, 210, 226, 230, 251, 262a-c, 271 a-c, 284a-c, 290, 300, 402) is adapted to receive light of a first wavelength and the photoluminescent features (182, 182a,b, 206a,b, 254, 266a-c, 291, 301) are adapted to emit light of a second wavelength in response to receiving light of the first wavelength.
(FR)L'invention concerne un dispositif de signalisation (180, 180', 190, 199, 200, 200', 208, 209, 242a-f, 250, 260, 270, 280) comprenant au moins une source de lumière (185), un guide d'ondes (184, 204, 210, 226, 230, 251, 290, 300, 402) ou un agencement de guides d'ondes (184a,b, 204a,b, 262a-c, 271 a-c, 284a-c) et des éléments photoluminescents (182, 182a,b, 206a,b, 254, 266a-c, 291, 301) couplés à celui-ci. Dans un mode de réalisation, un guide d'ondes (184, 184a,b, 204, 204a,b, 210, 226, 230, 251, 262a-c, 271 a-c, 284a-c, 290, 300, 402) est conçu pour recevoir de la lumière présentant une première longueur d'onde et les éléments photoluminescents (182, 182a,b, 206a,b, 254, 266a-c, 291, 301) sont conçus pour émettre de la lumière présentant une deuxième longueur d'onde en réponse à la réception de la lumière présentant la première longueur d'onde.
