    摘要： An electronic dimming ballast has a parallel loaded resonant output circuit plus a combination of pulse width modulation and frequency variation to accomplish the dimming of compact fluorescent lamps. The ballast operates at a fixed frequency throughout a selected range of ligth levels, with dimming control being done completely by duty cycle variation over this range of operation, and then smoothly moves to a variable frequency as the light output moves outside the selected range, with both duty cycle and frequency variation being the means of lamp light output control outside the selected range.

    摘要： In a fluorescent lighting controller, a switching circuit operates to selectively couple a bank of electronic ballasts (36) to an AC power source (34). The switching circuit comprises a pair of relays (RL3, RL4), preferably connected in parallel, with one of such relays having a controllably conductive device (Q1), such as an electronic switch, and preferably a triac, connected in series therewith. With the relays open, an air gap isolates the power source and ballasts. In closing the relays in sequence, one relay (RL3) provides a conductive path from the power source to the triac. After a suitable delay to allow the relay contacts to stabilize in the closed position, the triac is triggered to provide a conductive path from the power source to the ballasts, and a large current surge (as much as 300 amps) flows to the ballasts. After the current surge has subsided, the other relay (RL4) is closed to provide a direct conductive path between the power source and ballasts. As a result of this arrangement, the switching circuit is low cost, compact and reliable over an extended period of time.

    摘要： L'agencement de la plaque de couverture et de la plaque de support est destiné à des dispositifs montés contre un mur, tels que des interrupteurs, des affichages, des commutateurs muraux, l'agencement étant monté sur une boîte murale noyée dans le mur et ayant des dimensions totales de surface supérieures à celles de la boîte murale. La plaque de couverture est juxtaposée par dessus la surface frontale de la plaque de support et est espacée de cette dernière pour laisser un espace d'air entre la plaque de couverture et la plaque de support, créant ainsi une cheminée au travers de laquelle des courants d'air peuvent circuler. Le dispositif comprend un circuit électrique ayant un dispositif de production de chaleur, tel qu'un triac, qui est thermiquement connecté à la plaque de support et est connecté électriquement en série avec une charge commandée. La plaque de couverture projette une ombre le long des côtés verticaux de la plaque de support de sorte que les côtés verticaux de la plaque de support ne sont visibles que lorsque l'on regarde suivant des angles extrêmes par rapport à une ligne imaginaire perpendiculaire au plan de la plaque de support ou au mur dans lequel le dispositif est monté. La plaque de couverture semble flotter vis-à-vis du mur, et une bonne dissipation thermique est obtenue au travers de la cheminée créée entre la plaque de support et la plaque de couverture. Des moyens sont décrits pour la construction d'une famille de gradateurs muraux de profils bas et de dimensions conventionnelles qui satisfont les normes de température de fonctionnement des Underwriters Laboratories.
