Ora sempre pi\u00f9 persone prestano attenzione all'indice di resa cromatica (CRI), ma poche persone sanno cosa sia R9. In effetti, CRI e R9 sono due fattori molto importanti quando si sceglie l'illuminazione.<\/p>\n\n\n\n

1. Che cos'\u00e8 CRI R9?<\/a>
2. Perch\u00e9 CRI R9 \u00e8 importante?<\/a>
3. Qual \u00e8 un buon valore CRI R9?<\/a>
4. Perch\u00e9 il rosso \u00e8 cos\u00ec importante?<\/a><\/p>\n\n\n\n

Che cos'\u00e8 CRI R9?<\/h2>\n\n\n\n

CRI R9 \u00e8 uno dei campioni di colore di prova (TCS) utilizzati nel calcolo del CRI esteso. Molti produttori riporteranno tuttavia solo il CRI generale, che non include il punteggio CRI R9.<\/p>\n\n\n\n

R9 \u00e8 un punteggio che rappresenta la precisione con cui una sorgente luminosa riproduce un forte colore rosso e R9<\/a> \u00e8 in realt\u00e0 molto importante quando si parla di qualit\u00e0 della luce LED. In effetti, una certa percentuale di R9 si trova in tutti i colori che compongono il valore CRI, ma la capacit\u00e0 specifica di un prodotto di illuminazione di riprodurre accuratamente il rosso \u00e8 fondamentale per un'accurata resa cromatica complessiva.<\/p>\n\n\n

Perch\u00e9 \u00e8 importante CRI R9?<\/h2>\n\n\n\n

CRI R9 \u00e8 una metrica molto importante, infatti molte sorgenti luminose mancheranno di contenuto rosso, ma poich\u00e9 R9 non \u00e8 incluso nella media calcolata dal CRI, viene mostrato raramente.<\/p>\n\n\n\n

Come mostra il grafico sottostante, una sorgente luminosa pu\u00f2 effettivamente funzionare abbastanza bene con i primi 8 campioni di colore di prova, ottenendo un punteggio abbastanza buono per R1-R8. Per la metrica CRI Ra generale, ci\u00f2 significa che un LED con una scarsa resa cromatica del rosso pu\u00f2 ancora cavarsela con un Valutazione 80 CRI (Ra).<\/a>.<\/p>\n\n\n

Tuttavia, se osserviamo da vicino il valore R9, possiamo vedere che le prestazioni della luce sono molto scarse, soprattutto per quella rossa.<\/p>\n\n\n\n

Qual \u00e8 un buon valore CRI R9?<\/h2>\n\n\n\n

Il valore massimo possibile di R9 \u00e8 100, ma a differenza del numero CRI medio, il giudizio di R9 sar\u00e0 leggermente diverso.<\/p>\n\n\n\n

Matematicamente, R9 \u00e8 pi\u00f9 difficile da ottenere un punteggio elevato rispetto agli altri valori R che compongono il calcolo CRI, \u00e8 pi\u00f9 sensibile ai cambiamenti spettrali. Pertanto, un punteggio R9 di 50 o superiore sarebbe considerato "buono", mentre un punteggio R9 di 90 o superiore sarebbe considerato "eccellente".<\/p>\n\n\n\n

Di conseguenza, scoprirai che la maggior parte dei prodotti di illuminazione sul mercato raramente specifica un valore R9 e, anche se lo fa, di solito non \u00e8 superiore a 50.<\/p>\n\n\n\n

Perch\u00e9 il rosso \u00e8 cos\u00ec importante?<\/h2>\n\n\n\n

Il rosso \u00e8 richiesto in molte applicazioni, come la fotografia, i tessuti e la riproduzione delle tonalit\u00e0 della pelle umana. A volte gli oggetti che non ci sembrano rossi sono in realt\u00e0 combinazioni di colori, incluso il rosso. Ad esempio, il tono della pelle \u00e8 in gran parte influenzato dal rossore del sangue che scorre sotto la nostra pelle.<\/p>\n\n\n\n

Pertanto, la mancanza di luce rossa pu\u00f2 far sembrare le persone pallide, anche un po' verdastre, quindi \u00e8 nella fotografia o in altre applicazioni come la medicina, l'aspetto estetico \u00e8 fondamentale, e molte volte non pu\u00f2 essere corretto nemmeno in post-produzione e editing digitale .<\/p>\n\n\n\n

L'indice di resa cromatica e i valori R9 sono due caratteristiche importanti quando si tratta di selezionare le luci LED giuste per la propria applicazione.<\/p>","protected":false},"excerpt":{"rendered":"
