Title
(EN) SUPER EFFICIENT LED TUBE
(FR) TUBE À DEL SUPER EFFICACE
Abstract
(EN) The invention discloses LED tubes (300) that are very efficient and can operate with direct AC input or with existing inductor ballast. The LED tubes (300) make use of reactive components, such as capacitors (354, 355), to oppose input voltage as well as to limit the current. The LED tubes (300) have two circuit paths that can light up the LED tubes. The first circuit path is for the case where the LED tube has a direct AC input. The second circuit path is for the case where the LED tube is used in combination with inductor ballast and LED starter. As there are four input pins (321, 322, 331, 332) for LED tube (300), two input pins (321, 322) are used for the first circuit while the four input pins are used for the second circuit.
(FR) La présente invention concerne des tubes à DEL (300) qui sont très efficaces et peuvent fonctionner avec une entrée directe en courant alternatif ou avec un ballast inductif existant. Les tubes à DEL (300) utilisent des composants réactifs, tels que des condensateurs (354, 355) pour opposer la tension d’entrée ainsi que pour limiter le courant. Les tubes à DEL (300) présentent deux trajets de circuit qui peuvent allumer les tubes à DEL. Le premier trajet de circuit est utile dans le cas où le tube à DEL présente une entrée directe en courant alternatif. Le second trajet de circuit est utile dans le cas où le tube à DEL est utilisé en association avec un ballast inductif et un démarreur de DEL. Comme il y a quatre broches d’entrée (321, 322, 331, 332) destinées au tube à DEL (300), deux broches d’entrée (321, 322) sont utilisées pour le premier circuit, pendant que les quatre broches d’entrée sont utilisées pour le second circuit.
