Abstract

L’invention concerne un crayon luminescent avec DEL comprenant un tube (1), un élément d’écriture (2) à l’intérieur du tube (1), une pile (3) et au moins une DEL (7). La pile (3) est positionnée dans la portion supérieure du tube (1) et il s’agit d’une pile à goujon. La DEL (7) est positionnée dans la portion inférieure du tube (1). Un module d’augmentation de tension (6) ayant un circuit d’augmentation de tension est disposé entre la pile (3) et la DEL (7) pour conduire l’électricité. L’élément d’écriture passe à travers le trou central du module d’augmentation de tension (6). Comparé à l’art antérieur, attribué pour adopter le module d’augmentation de tension, la présente invention peut utiliser une seule pile ordinaire de 1,5V pour allumer la DEL. Comme la DEL est disposée dans la portion inférieure du tube, la zone d’éclairage peut se concentrer au niveau de la pointe du crayon. Du fait que l’élément d’écriture passe par le trou central du module, il est possible d’utiliser un élément d’écriture mince dans ce crayon luminescent avec DEL.
