Leur aspect varie en fonction de la source lumineuse et des conditions environnantes. Si vous observez attentivement une ombre projet\u00e9e sous une lumi\u00e8re \u00e9lectrique, vous remarquerez que le centre est particuli\u00e8rement sombre tandis que les bords sont plus clairs. La zone centrale la plus sombre s'appelle l'ombre propre, et la zone plus claire qui l'entoure s'appelle la p\u00e9nombre. Ces ph\u00e9nom\u00e8nes sont \u00e9troitement li\u00e9s au fait que la lumi\u00e8re se propage en ligne droite.<\/p>\n<p>Par exemple, posez une bo\u00eete \u00e0 th\u00e9 cylindrique sur une table et allumez une bougie \u00e0 c\u00f4t\u00e9. La bo\u00eete projettera une ombre bien distincte. Si deux bougies sont allum\u00e9es \u00e0 c\u00f4t\u00e9, deux ombres se chevauchant mais non identiques se formeront. La zone o\u00f9 les deux ombres se chevauchent ne re\u00e7oit la lumi\u00e8re d\u2019aucune des deux bougies et est compl\u00e8tement sombre : c\u2019est l\u2019ombre propre. La zone environnante ne re\u00e7oit la lumi\u00e8re que d\u2019une seule bougie, cr\u00e9ant ainsi une p\u00e9nombre partiellement \u00e9clair\u00e9e.<br \/>\nSi l'on allume trois ou quatre bougies, l'ombre propre diminue progressivement, tandis que la p\u00e9nombre pr\u00e9sente plusieurs niveaux de luminosit\u00e9. Les ombres produites par les lumi\u00e8res \u00e9lectriques se composent d'une ombre propre et d'une p\u00e9nombre pour la m\u00eame raison. Plus la surface \u00e9mettant de la lumi\u00e8re est grande, plus l'ombre propre est petite. Si l'on dispose un cercle de bougies autour du bidon, l'ombre propre dispara\u00eet compl\u00e8tement et la p\u00e9nombre devient trop faible pour \u00eatre visible.<\/p>\n<p>Les lampes chirurgicales sans ombre sont con\u00e7ues selon ce principe. Plusieurs sources lumineuses \u00e0 haute intensit\u00e9 sont dispos\u00e9es en cercle sur la t\u00eate de la lampe, cr\u00e9ant ainsi une vaste zone \u00e9clair\u00e9e. La lumi\u00e8re atteint la table d'op\u00e9ration sous plusieurs angles, offrant une luminosit\u00e9 suffisante tout en emp\u00eachant la formation d'une ombre nette. C'est pourquoi on les appelle des lampes sans ombre.<\/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-ombre-p\u00e9nombre\" 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);\">Entretien courant<\/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>Inspection quotidienne<br \/>\nV\u00e9rifiez l\u2019\u00e9tat de fonctionnement des ampoules sur les mod\u00e8les PRX6000 et PRX8000 en pla\u00e7ant une feuille de papier blanc dans la zone de travail.
