Lighting appts. with mains fed lights - has two dielectric containers and high-frequency generator with lighting connected to terminals with induced electromagnetic field

摘要

The lighting appts. has a lamp (11) fed by the mains (3,4) and has two separate dielectric boxes or containers (1,10). The first container has a high frequency generator (2) connected to the mains and at least one induction element (5). The second container is fixed w.r.t. the first container and has at least one lamp (11) with terminals (14,15) with an inductor element (13) opposed to the other inductor in cooperation with the magnetic field induced by the other inductor. The high frequency generator operates at high-frequency of the order of several dozen KHz (for example 40 KHz). The second container is in the shape of a parallelepiped and made of plastic dielectric material and has an analog coil. The collector is a few millimetres from the inductor and has self-inductances of L1 and L2. The inductor and collector have circular coils and are magnetically coupled and form a high-frequency transformer. The lamp is about 50 watts and has a 220 V supply. USE/ADVANTAGE - Mobile. Assures good isolation and electric protection. Enables utilisation of 12 V lamps without need for transformer.
