Abstract

DISPOSITIVO OPTICO PARA UN INDICADOR DE HUMOS BASADO EN EL PRINCIPIO DE DISPERSION DE LA LUZ. CONSTA DE UN EMISOR OPTICO (1) QUE DIRIGE RADICACION ELECTROMAGNETICA A UN ESPACIO DE ENSAYO (3) EN EL QUE PUEDEN ENCONTRARSE PARTICULAS DE HUMO A SEÑALAR; DE UN RECEPTOR OPTICO (2), FORMANDO UN ANGULO AGUDO B CON EL EMISOR OPTICO (1), QUE ESTA DIRIGIDO AL ESPACIO DE ENSAYO (3) PARA RECIBIR LA RETORRADIACION DISPERSADA POR LAS PARTICULAS DE HUMO; DE DOS LENTES OPTICAS (4,5), UNA DELANTE DEL EMISOR Y OTRA DELANTE DEL RECEPTOR; DE VARIOS DIAFRAGMAS (10,11) QUE LIMITAN LAS TRAYECTORIAS DE LOS RAYOS DEL EMISOR Y DEL RECEPTOR; DE DOS DISPERSORES DE ESTRIAS (6,7) QUE CIRCUNDAN LA TRAYECTORIA DE LOS REYOS ENTRE EL EMISOR (1) Y LA LENTE (4), Y ENTRE LA LENTE (5) Y EL RECPTOR (2); Y DE DOS SUMIDEROS DE LUZ (8,9) CONSTITUIDOS POR VARIOS DIAFRAGMAS.
