Abstract

L'invention porte sur une lampe, qui a une tête de lampe rotative, et qui comprend une base de lampe (2) et une tête de lampe (1), muni d'un arbre rotatif (3) qui relie la tête de lampe et la base de lampe, lequel arbre rotatif comprend quatre têtes d'arbre (31) disposées sous une forme en croix, chaque tête d'arbre ayant une fente circulaire (311) ouverte dans la direction périphérique de la tête d'arbre, chaque fente circulaire comportant un élément de fixation à encliquetage (4) pouvant tourner par rapport à la tête d'arbre ; les deux éléments de fixation à encliquetage disposés à l'opposé l'un de l'autre dans la première ligne de la forme en croix de l'arbre rotatif sont reliés de façon fixe au bas de la tête de lampe, et les deux éléments de fixation à encliquetage disposés à l'opposé l'un de l'autre dans l'autre ligne de la forme en croix de l'arbre rotatif sont reliés de façon fixe à la base de lampe disposée à l'opposé du bas de la tête de lampe. La rotation de la tête de lampe par rapport à la base de lampe obtenue par l'utilisation de l'arbre rotatif avec la structure en forme de croix permet à la tête de lampe d'être réglée par rapport à la base de lampe à n'importe quel angle dans une plage de 360 degrés, augmentant la plage de réglage de rotation de la tête de lampe, de façon à rendre la direction d'éclairage plus souple ; cela peut empêcher le fil d'alimentation d'être emmêlé en nœuds du fait de la rotation de la tête de lampe ; et cela produit également une structure compacte à un volume de lampe réduit.
