A flexible tubular light having the flowing flash effect includes a transparent inner cladding layer and a plurality of PCBs that are connected with each other in series and are provided within the through-hole of the inner cladding layer. Each PCB is provided with a plurality of LEDs, corresponding quantity of current limiting resistors and chips for driving the LEDs. The PCBs are connected in parallel with the copper strands of the inner cladding layer. The signal wires of the LED driving chips are connected in series with a controller. A transparent outer cladding layer encloses the inner cladding layer. The LED driving chip comprises serial shift registers and output registers, and adopts cascade connection and three high current output signals. The PCBs are provided with main wires, and the main wires of the two adjacent PCBs are connected in parallel. The flexible tubular light having the flowing flash effect realizes the signal regeneration, signal cascade connection and signal transmission without limit, and can be bended and cut. [FIG.2]

L'invention concerne une lampe tubulaire flexible présentant un effet de clignotement circulant, laquelle lampe comprend une couche de revêtement interne transparente, une pluralité de cartes de circuits imprimés connectées entre elles en chaîne et disposées dans l'orifice de passage de la couche de revêtement interne. Chacune des cartes de circuits imprimés comporte une pluralité de DEL, une quantité correspondante de résistances en série limitant le courant et des puces de commande des DEL. Les cartes de circuits imprimés sont connectées en parallèle dans les fils de cuivres de la couche de revêtement interne. Les fils de signal des puces de commande des DEL sont connectées en séries avec la commande. Une couche de revêtement externe transparente enveloppe la couche de revêtement interne. Les puces de commande des DEL comprennent plusieurs minuteries de décalage en série et de sortie, adoptent la concaténation en pont et alimentent la sortie de commande en courant. Les fils principaux sont disposés sur les cartes de circuits imprimés, et les fils principaux de cartes adjacentes sont connectés en parallèle.
