II the temperature of an obfect continues to
increase, it will eventually begin giving off light.
At this time, there is a fixed relationship
between the ob)ect's temperature and Its "light
color " The temperature ol the ob)ect radiating
the light is expressed in absolute temperature
(K). This Is also known as the color
temperature, which In turn starrds for "light
color." As color temperature ir>creases. the
light color changes from red to yellow to white
to blue.

Si la température d'un obfet continue à
augmenter, elle commence à émettre la
lumière. Dès cet instant. Il existe un rapport
fixe entre la lempéralure de l'obfet el sa
"couteur de lumtèie" La lempéralure d'un objr
Irradiant de la lumière est exprimée en
température absolue (degrés Kelvtn).
Ceci est également connu sous l'appellation d<
température de couleur, gui tient lieu de
"couleur de lumière". Au fur et é mesure de
l'élévetion de la température de couleur, la
couleur de la lumière passe successivement d<
rouge, au (aune, au blanc, au bleu.
