Abstract

LAS FUENTES DE LUZ QUE PROPONE LA INVENCION EMITEN LUZ EN TODAS LAS DIRECCIONES. CUANDO SE INSTALA O SE ENCASTRA UNA FUENTE DE LUZ QUE ESTA SITUADA EN EL BORDE DE UNA LAMPARA DE FORMA PLANA E IRRADIA AL INTERIOR DE DICHA LAMPARA, SE OBSERVA QUE UNA GRAN PARTE DE LA LUZ QUE HAY EN EL BORDE DE LAS SUPERFICIES QUE SE DESEAN ILUMINAR SALE DE LA LAMPARA. ESTE EFECTO, VISIBLE EN FORMA DE BORDE LUMINOSO, SE PRODUCE EN TODAS LAS CONFIGURACIONES CONOCIDAS, YA QUE EL ANGULO DE INCIDENCIA DE LA LUZ EN ESTA ZONA ES MENOR QUE EL ANGULO DE LA REFLEXION TOTAL, DE MODO QUE LA MAYOR PARTE DE LA LUZ SALE FUERA. ESTA CARACTERISTICA NATURAL LIMITA CONSIDERABLEMENTE EL APROVECHAMIENTO DE LA LUZ IRRADIADA PARA EL EFECTO LUMINOSO EN TODA LA ZONA DE LA LAMPARA. UNA CARACTERISTICA PRINCIPAL DE LA PRESENTE SOLICITUD DE PATENTE ES LA COMPENSACION DE ESTE EFECTO Y, POR TANTO, LA POSIBILIDAD DE APROVECHAR LA PARTE DE LUZ QUE SE DESPRECIA EN LAS APLICACIONES CONOCIDAS.
