Guida ai Lumens: come faccio a sapere quanti Watt e Lumens mi servono?

 

Un comune errore è quello di effettuare i propri acquisti a seconda dei Watt. Soprattutto nella scelta dei prodotti a LED, l’ attenzione deve essere rivolta ai Lumens che essa genera. Inanzitutto, un buon prodotto power LED, è oggi in grado di raggiungere rese almeno di 60 Lumens per Watt che si possono, in alcuni casi, spingere anche vicino ai 90-100 lumens. La potenza lunimosa, ovvero il flusso luminoso,non è altro che il totale dei lumens prodotti da una lampada. Per calcolare l’ illuminamento espresso in lux per metro quadro necessario, dovrete dividere il flusso luminoso (totale lumens di uno o più apparecchi illuminanti) per la superfice dell’ ambiente da illuminare.

Per esempio per illuminare un ufficio, sono consigliabili circa 300-400 lumens per metro quadro di superfice. Se il vostro ufficio è di 100 metri quadri, avrete bisogno di circa 30,000-40,000 lumens di potenza lumiosa.

Illuminamento = 30,000 /100 = 300 lumens per metro quadro.

Per una corretta installazione è necessario conoscere il cono luce di ogni sorgente luminosa. Il cono luce ci permette di sapere i lux che la sorgente luminosa è in grado di creare in superficie a seconda della distanza di installazione.

I valori consigliabili per metro quadro sono i seguenti:

ILLUMINAZIONE CIVILE: (lux =lumens per metro quadro)

Zona di Passaggio: 50 – 150 lux
Zona Lettura: 200 – 500 lux
Cucina: 200 – 500 lux
Bagno: 100-150 lux
Bagno (specchio): 400 lux
Camere: 50-150 lux

ILLUMINAZIONE COMMERCIALE:

Uffici generali: 300 – 400 lux
Uffici disegno, attività tecnica: 400 – 500 lux

ILLUMINAZIONE INDUSTRIALE.

Capannoni Generici: 150 lux
Capannoni con attività specifiche (es. saldatura): 300 lux

  1. Salve, in riferimento all’esempio riportato per l’ufficio leggo che per 100mq si ha bisogno di 3000/4000 lumens.
    Moltiplicando per 300/400 non dovrebbero essere 30000/40000?
    Anche nell’esempio di sotto 3000 divviso 100 è uguale 300.
    E’ un errore di battuta o capisco male io qualche passaggio?

  2. grazie, un sito utile per calcolare l’illuminazione del soffitto a volta della cucina e della camera con nastri led.

  3. ….mi sa che vi sono delle divisioni sbagliate 3000lumen /100 fa 30lux per metro quadro e 300 lux x 100 mq fa 30 mila lumen

  4. Just desire to say your article is as surprising. The clearness in your publish is
