Abstract

LA PRESENTE INVENCION HACE RELACION A UNA TECLA EMISORA DE LUZ PARA PROPOSITOS OPERATIVOS, POR EJEMPLO UN BOTON NUMERICO SOBRE UN APARATO TELEFONICO, EN LA QUE LA TECLA INCLUYE UN CUERPO QUE ESTA DOBLEMENTE MOLDEADO A PARTIR DE DOS MATERIALES PLASTICOS DIFERENTES, DE LOS CUALES UNO ES TRASLUCIDO Y EL OTRO ES OPACO. UN DISPOSITIVO EMISOR DE LUZ, TAL COMO UN DIODO EMISOR DE LUZ, ESTA COLOCADO PARA EMITIR LUZ SOBRE LA PARTE BAJA DE LA TECLA DE FORMA QUE LA LUZ SEA CONDUCIDA A TRAVES DEL MATERIAL TRASLUCIDO Y SEA EMITIDA SOBRE LA PARTE SUPERIOR DE LA TECLA. DE ACUERDO A LA INVENCION, SE FORMA UNA RANURA (5) ENTRE EL MATERIAL TRASLUCIDO (2) Y EL MATERIAL OPACO (2) SOBRE EL LADO SUPERIOR DE LA TECLA (1) DE FORMA QUE LA LUZ CONDUCIDA A TRAVES DEL MATERIAL TRASLUCIDO (3) SE DISPERSARA UNIFORMEMENTE Y SERA POR TANTO VISIBLE DESDE TODAS LAS DIRECCIONES.
