RENDIMIENTO O EFICACIA<br />

LUMINOSA<br />

Es la relación existente entre el flujo luminoso y la potencia<br />

absorbida.<br />

No toda la energía eléctrica consumida por una fuente de luz<br />

se transforma en luz visible. Parte se pierde por calor, radiación<br />

no visible (infrarrojos o ultravioleta), etc.<br />

LUMINOUS PERFORMANCE OR<br />

EFFICACY<br />

Luminous performance or efficacy is the relation between<br />

the luminous flux and the absorbed power.<br />

Not all the electric power used by a light source is transformed<br />

into visible light. Part of this is lost due to heat, non-visible<br />

radiation (infrared or ultraviolet), etc.<br />

Luz visible<br />

Visible light<br />

Pérdidas por calor<br />

Losses due to heat<br />

Potencia eléctrica consumida<br />

Electric power used<br />

Pérdidas por<br />

radiaciones invisibles<br />

Losses due to<br />

invisible radiations<br />
