Co je to LED \u010dip<\/h2>\n\n\n

LED \u010dip, ozna\u010dovan\u00fd tak\u00e9 jako LED \u010dipov\u00e9 j\u00e1dro (LED die), je mal\u00e9 semi-vodi\u010dov\u00e9 za\u0159\u00edzen\u00ed, kter\u00e9 slou\u017e\u00ed jako hlavn\u00ed sou\u010d\u00e1stka LED diody. Je zodpov\u011bdn\u00fd za p\u0159em\u011bnu elektrick\u00e9 energie na sv\u011btlo. LED \u010dip je vyroben z polovodi\u010dov\u00e9ho materi\u00e1lu, typicky arsenidu galia (GaAs) nebo nitridu galia (GaN), kter\u00fd je dopov\u00e1n p\u0159\u00edm\u011bsemi pro dosa\u017een\u00ed po\u017eadovan\u00fdch elektrick\u00fdch vlastnost\u00ed.<\/p>\n

P\u0159i pr\u016fchodu elektrick\u00e9ho proudu LED \u010dipem proch\u00e1z\u00ed proud PN p\u0159echodem, kter\u00fd vznik\u00e1 spojen\u00edm dvou r\u016fzn\u00fdch typ\u016f polovodi\u010dov\u00fdch materi\u00e1l\u016f. Na PN p\u0159echodu doch\u00e1z\u00ed ke rekombinaci elektron\u016f a d\u011br, \u010d\u00edm\u017e se uvol\u0148uje energie ve form\u011b foton\u016f \u2013 \u010d\u00e1stic sv\u011btla. Tento jev se naz\u00fdv\u00e1 elektroluminiscence.<\/p>\n\n\n\n

LED \u010dipy se dod\u00e1vaj\u00ed v r\u016fzn\u00fdch barv\u00e1ch, v\u010detn\u011b \u010derven\u00e9, zelen\u00e9, modr\u00e9 a b\u00edl\u00e9. Barva sv\u011btla vyza\u0159ovan\u00e9ho LED \u010dipem je ur\u010dena materi\u00e1ly pou\u017eit\u00fdmi v PN p\u0159echodu. Nap\u0159\u00edklad modr\u00e9 LED \u010dipy se b\u011b\u017en\u011b pou\u017e\u00edvaj\u00ed v kombinaci se \u017elut\u00fdm luminoforem k vytvo\u0159en\u00ed b\u00edl\u00e9ho sv\u011btla. Tyto \u010dipy b\u00fdvaj\u00ed namontov\u00e1ny na substr\u00e1t, jako je deska plo\u0161n\u00fdch spoj\u016f (PCB), a n\u00e1sledn\u011b zality do ochrann\u00e9ho pouzdra. Pouzdro nejen chr\u00e1ni LED \u010dip p\u0159ed fyzick\u00fdm a chemick\u00fdm po\u0161kozen\u00edm, ale poskytuje tak\u00e9 mechanickou, elektrickou, tepelnou a optickou podporu.<\/p>\n
