A pocket lamp consisting of a base body (10) and a lamp head (12) with at least two luminous diodes (32a, 32b), each of which having an optical device (44a) associated with one of said luminous diodes (32a, 32b) (44a), said optical device being used to focus the light radiated by the respective luminous diode, and respectively one tube body (56a, 56b, 56c) disposed between one of the luminous diodes (32a,32b) and the associated optical device (44a) for focussing the light radiated by the respective luminous diode. The tubes (56a, 56b, 56c) are embodied in such a way that substantially prevent light from one of the luminous diodes from penetrating into (32a, 32b) an optical device for focussing the light radiated by the respective luminous diode associated with one of the other luminous diodes (32a,32b).
La présente invention concerne une lampe de poche présentant: un corps de base (10); une tête de lampe (12) comprenant au moins deux diodes luminescentes (32a, 32b) présentant chacune un système optique (44a) associé à l'une des diodes luminescentes (32a, 32b) et destiné à focaliser la lumière émise par la diode luminescente respective; et respectivement un tube (56a, 56b, 56c) disposé entre l'une des diodes luminescentes (32a, 32b) et le système optique (44a) associé destiné à focaliser la lumière émise par la diode luminescente respective. Les tubes (56a, 56b, 56c) sont conçus de sorte que dans une large mesure ils empêchent respectivement la pénétration de la lumière issue de l'une des diodes luminescentes (32a, 32b), dans le système optique associé à une autre des diodes luminescentes (32a, 32b) et destiné à focaliser la lumière émise par la diode luminescente respective.
