The tube (1) has a cover comprising an interior surface that forms opposite separation panels to define a receiving chamber inside the cover. A retaining unit of the cover is formed in an interior surface of a heat dissipation opening (113) in the chamber. A heat dissipation element has a lower surface comprising a foot. The element is placed in the chamber from an end of the cover, so that the foot corresponds to the retaining unit. A circuit board has a luminescent chip to emit light, where the board is placed on an upper surface of the dissipation element. |
