CA 2303868

A cable lamp which is powered by a low-voltage battery and which comprises a cable (10). Fitted on one end of the cable (10) is a fitting (14) for a fluorescent bulb (21), while the other end of the cable has fitted thereon a battery connection means (30, 40) for connecting both cable conductors (11, 12) to respective battery terminals. The lamp also includes an electronic HF ignition means (22) for igniting the bulb. The ignition means (22) is adapted for both AC and DC mains voltages and is connected directly to the bulb (21). The battery connection means includes a terminal clip (30) that has a converter (18) which converts the battery low-voltage to DC mains voltage. The converter (18) is encapsulated in a radiation impervious housing (322, 323, 324) which forms on the one hand a high-frequency transformer component of the converter (18) and a converter cooling means on the other hand.

Cette baladeuse est alimentée par une batterie basse tension et elle comprend un câble (10), à une extrémité duquel on a monté un embout (14) destiné à une ampoule fluorescente (21), et à l'autre extrémité duquel on a monté des moyens de raccordement (20, 40) à une batterie, servant à connecter les deux conducteurs (11, 12) du câble aux bornes respectives de la batterie. Cette baladeuse comprend également des moyens d'allumage électronique haute fréquence (22), destinés à allumer la lampe, conçus pour des tensions à la fois en courant alternatif et en courant continu, et reliés directement à l'ampoule (21). Les moyens de raccordement à la batterie comprennent une pince (30) pour cosses de batterie, laquelle possède un convertisseur (18) convertissant la basse tension de la batterie en tension en courant continu. Ce convertisseur (18) est encapsulé dans un boîtier (322, 323, 324) étanche aux rayonnements et formant, d'une part, un composant de transformateur haute fréquence du convertisseur (18) et, d'autre part, des moyens de refroidissement du convertisseur.
