Su aspecto var\u00eda en funci\u00f3n de la fuente de luz y de las condiciones del entorno. Si observas con atenci\u00f3n una sombra proyectada bajo una luz el\u00e9ctrica, notar\u00e1s que el centro es especialmente oscuro, mientras que los bordes son m\u00e1s claros. La zona central m\u00e1s oscura se denomina \u00abumbra\u00bb, y la zona m\u00e1s clara que la rodea se denomina \u00abpenumbra\u00bb. Estos fen\u00f3menos est\u00e1n estrechamente relacionados con el hecho de que la luz se propaga en l\u00ednea recta.<\/p>\n<p>Por ejemplo, coloca un bote cil\u00edndrico de t\u00e9 sobre una mesa y enciende una vela a su lado. La lata proyectar\u00e1 una sombra bien definida. Si se encienden dos velas a su lado, se formar\u00e1n dos sombras que se superponen, pero que no son id\u00e9nticas. La zona en la que se superponen las dos sombras no recibe luz de ninguna de las velas y queda completamente a oscuras: esa es la umbra. La zona circundante recibe luz de una sola vela, lo que crea una penumbra parcialmente iluminada.<br \/>\nSi se encienden tres o cuatro velas, la umbra se va reduciendo gradualmente, mientras que la penumbra presenta varios niveles de intensidad luminosa. Las sombras producidas por las luces el\u00e9ctricas constan de una umbra y una penumbra por la misma raz\u00f3n. Cuanto mayor es la superficie emisora de luz, m\u00e1s peque\u00f1a es la umbra. Si se coloca un anillo de velas alrededor del recipiente, la umbra desaparece por completo y la penumbra se vuelve demasiado tenue como para verla.<\/p>\n<p>Las l\u00e1mparas quir\u00fargicas sin sombras est\u00e1n dise\u00f1adas seg\u00fan este principio. Varias fuentes de luz de alta intensidad se disponen en c\u00edrculo en el cabezal de la l\u00e1mpara, creando una amplia zona iluminada. La luz incide sobre la mesa de operaciones desde m\u00faltiples \u00e1ngulos, lo que proporciona una luminosidad suficiente y evita que se forme una umbra definida. Por eso se denominan l\u00e1mparas sin sombras.<\/p>\n<\/div><div class=\"fusion-image-element\" style=\"--awb-margin-bottom:16px;--awb-caption-title-font-family:var(--h2_typography-font-family);--awb-caption-title-font-weight:var(--h2_typography-font-weight);--awb-caption-title-font-style:var(--h2_typography-font-style);--awb-caption-title-size:var(--h2_typography-font-size);--awb-caption-title-transform:var(--h2_typography-text-transform);--awb-caption-title-line-height:var(--h2_typography-line-height);--awb-caption-title-letter-spacing:var(--h2_typography-letter-spacing);\"><span class=\"fusion-imageframe imageframe-none imageframe-4 hover-type-none\"><img decoding=\"async\" width=\"1366\" height=\"683\" title=\"07-umbra-penumbra\" src=\"https:\/\/www.medeco-medical.com\/wp-content\/uploads\/2026\/08\/07-umbra-penumbra.webp\" data-orig-src=\"https:\/\/www.medeco-medical.com\/wp-content\/uploads\/2026\/08\/07-umbra-penumbra.webp\" alt class=\"lazyload img-responsive wp-image-9295\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%271366%27%20height%3D%27683%27%20viewBox%3D%270%200%201366%20683%27%3E%3Crect%20width%3D%271366%27%20height%3D%27683%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-srcset=\"https:\/\/www.medeco-medical.com\/wp-content\/uploads\/2026\/08\/07-umbra-penumbra-200x100.webp 200w, https:\/\/www.medeco-medical.com\/wp-content\/uploads\/2026\/08\/07-umbra-penumbra-400x200.webp 400w, https:\/\/www.medeco-medical.com\/wp-content\/uploads\/2026\/08\/07-umbra-penumbra-600x300.webp 600w, https:\/\/www.medeco-medical.com\/wp-content\/uploads\/2026\/08\/07-umbra-penumbra-800x400.webp 800w, https:\/\/www.medeco-medical.com\/wp-content\/uploads\/2026\/08\/07-umbra-penumbra-1200x600.webp 1200w, https:\/\/www.medeco-medical.com\/wp-content\/uploads\/2026\/08\/07-umbra-penumbra.webp 1366w\" data-sizes=\"auto\" data-orig-sizes=\"(max-width: 1024px) 100vw, (max-width: 768px) 100vw, 1200px\" \/><\/span><\/div><div class=\"fusion-title title fusion-title-5 fusion-title-text fusion-title-size-two\" style=\"--awb-margin-top-small:0px;--awb-margin-bottom-small:20px;--awb-font-size:26px;\"><div class=\"title-sep-container title-sep-container-left fusion-no-large-visibility fusion-no-medium-visibility fusion-no-small-visibility\"><div class=\"title-sep sep- sep-solid\" style=\"border-color:var(--awb-color3);\"><\/div><\/div><span class=\"awb-title-spacer fusion-no-large-visibility fusion-no-medium-visibility fusion-no-small-visibility\"><\/span><h2 class=\"fusion-title-heading title-heading-left fusion-responsive-typography-calculated\" style=\"margin:0;text-transform:capitalize;font-size:1em;--fontSize:26;--minFontSize:26;line-height:var(--awb-typography1-line-height);\">Mantenimiento peri\u00f3dico<\/h2><span class=\"awb-title-spacer\"><\/span><div class=\"title-sep-container title-sep-container-right\"><div class=\"title-sep sep- sep-solid\" style=\"border-color:var(--awb-color3);\"><\/div><\/div><\/div><div class=\"fusion-text fusion-text-5\"><p>Inspecci\u00f3n diaria<br \/>\nComprueba el estado de funcionamiento de las l\u00e1mparas de los modelos PRX6000 y PRX8000 colocando una hoja de papel blanco en la zona de trabajo. Si aparece una sombra en forma de arco, sustituye la l\u00e1mpara correspondiente. Aseg\u00farate de que el mango esterilizable est\u00e9 correctamente instalado; una instalaci\u00f3n correcta se confirma con dos chasquidos. Limpia las superficies exteriores con una soluci\u00f3n alcalina suave, como agua jabonosa. Evita los productos de limpieza a base de cloro, que pueden da\u00f1ar el metal, y los productos a base de alcohol, que pueden da\u00f1ar el pl\u00e1stico y las superficies pintadas.<\/p>\n<p>Inspecci\u00f3n mensual<br \/>\nComprueba el sistema de alimentaci\u00f3n de emergencia y la bater\u00eda desconectando la alimentaci\u00f3n de 220 V. Aseg\u00farate de que el sistema de alimentaci\u00f3n de emergencia se active autom\u00e1ticamente.<\/p>\n<p>Vida \u00fatil de la bombilla<br \/>\nLa vida \u00fatil media de una bombilla es de aproximadamente 1.000 horas. Por lo general, el portal\u00e1mparas debe sustituirse una vez al a\u00f1o, siempre que se utilicen bombillas homologadas por ALM.<\/p>\n<p>Inspecci\u00f3n anual<br \/>\nEl mantenimiento anual debe ser realizado por un ingeniero certificado. Esto incluye apretar las conexiones de los cables de alimentaci\u00f3n, los tornillos de las articulaciones y las escobillas el\u00e9ctricas; ajustar los l\u00edmites de rotaci\u00f3n, la tensi\u00f3n de funcionamiento de las l\u00e1mparas y los frenos de las articulaciones; e inspeccionar la alineaci\u00f3n de la suspensi\u00f3n, el equilibrio del sistema, los elementos de fijaci\u00f3n, el funcionamiento de los frenos, la disipaci\u00f3n del calor, los portal\u00e1mparas, las l\u00e1mparas, el mango esterilizable, la iluminancia y el di\u00e1metro del campo luminoso.<\/p>\n<\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":9300,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[100],"tags":[],"class_list":["post-9289","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-surgical-light"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Why Are Shadowless Lamps \u201cShadowless\u201d? - Shanghai Medeco Industry Co., Ltd.<\/title>\n<meta name=\"description\" content=\"Why are shadowless lamps shadowless?
