FUNDAMENTAL CONCEPTS<br />

OF LIGHTING DESIGN<br />

QUÉ ES LA LUZ?<br />

El espectro visible<br />

La luz se puede considerar como una radiación electromagnética,<br />

llamada energía radiante. Esta energía es capaz de activar la<br />

retina del ojo humano y producir una sensación visual.<br />

El concepto de luz tradicional está basado en concepción antropológica,<br />

a través de la cual el hombre se conecta visualmente<br />

con el mundo que lo rodea.<br />

El espectro visible, que comprende las emisiones radiantes de<br />

longitud de onda desde 380 nm hasta 780 nm, es la porción del<br />

espectro electromagnético percibida por el ojo humano.<br />

La luz blanca percibida es una mezcla de todas las longitudes<br />

de onda visibles. El espectro visible se puede descomponer en<br />

sus diferentes longitudes de onda mediante un prisma de cuarzo<br />

que refracta las distintas longitudes de onda selectivamente.<br />

WHAT IS LIGHT?<br />

The visible spectrum<br />

Light can be considered an electromagnetic radiation, called<br />

“radiant energy”. This energy is capable of activating the human<br />

eye’s retina and produce a visual sensation.<br />

The traditional concept of light is based on an anthropological<br />

conception, according to which the human being connects<br />

visually with the world around them.<br />

The visible spectrum, which comprises the radiant emissions<br />

with a wavelength between 380 and 780 nm, is the portion of<br />

the electromagnetic spectrum which is visible to the human<br />

eye.<br />

The white light perceived by the eye is a mixture of all the visible<br />

wavelengths. The visible spectrum can be broken down<br />

into its different wavelengths using a quartz prism which reflects<br />

each of them separately.<br />
