Takže známe už dvě proměnné ze tří – to je slučný základ. Pokud platí pro intenzitu osvětlení, že E=FI/S, pak platí, že světelný tok FI (v lumenech= E (v luxech) x S (v m2). Takže suma sumárum mám potřebu osvětlení 300 lx a mám plochu 24 m2. 300 x 24 je 7200 lm (lumenů). Takže potřebuji 7200 lumenů, abych v téhle místnosti dosáhl 300 lx. ملاعب اليورو 2024 Teď ještě zavedu maďarskou konstantu třeba 0,7. العاب بتتلعب على النت To je konstanta, kterou jsem si zvolil.

Tkaže koeficient ztráty osvětlení bude 0.7. Takže nově nyní potřebuji světelný tok 7200/0.7=cca 10300 lm. Dokončení příště.
