L'invention concerne un support d'écriture éclairé comprenant un appareil doté d'une surface d'écriture (16) portable, un ensemble d'éclairage (12) relié à l'appareil et un commutateur (32) pour régler le courant électrique avec l'ensemble d'éclairage. La surface d'écriture portable comporte une surface d'écriture de poche. L'ensemble d'éclairage est constitué d'une source lumineuse (34, 36) conçue pour, lorsqu'elle est en marche, émettre sélectivement un premier spectre lumineux ou un second spectre lumineux différent dans une portion visible de la plage du premier spectre. Un boîtier entourant partiellement la source lumineuse dirige la lumière émise sur la surface d'écriture. La source lumineuse est dotée d'un premier type (36) de diode électroluminescente (DEL) émettant une première couleur de lumière, et d'un second type (34) de DEL émettant une seconde couleur de lumière. La première couleur comprend une lumière presque rouge en apparence et la seconde une lumière presque blanche en apparence.
