LED DIODA<\/h2>\n

Jak m\u016f\u017eeme vid\u011bt na obr.1, tak plus ( kladn\u00e9 nap\u011bt\u00ed ) vstupuje na Anodu led diody a prot\u00e9k\u00e1 ke katod\u011b.<\/p>\n

Jsou led diody tzv. RGB tj. dioda, kter\u00e1 sv\u00edt\u00ed v\u00edcebarevn\u00e1 led – \u010cerven\u00e1, zelen\u00e1, modr\u00e1. Tyto diody maj\u00ed spole\u010dnou katodu.<\/p>\n
