Abstract
<B>''AMPOLA FOTO-TRANSISTORA COM SOBRETENSOR PARA LUMINáRIAS''<D>. O presente modelo de utilidade apresenta um sistema novo de acionamento para luminárias, através de um circuito foto transistorizado utilizando um foto-transistor ao invés de uma foto-célula, além de possuir um sistema automático de sobre tensões que tem por finalidade proteger a AMPOLA de tensões maiores que as nominais, acrescidas dos ± 10% que se dão em função de descargas atmosféricas, descargas por faiscamentos e outros, sendo que esta AMPOLA quando ligada a rede elétrica funciona normalmente, fazendo com que a luminária se ascenda quando escurecer e se apague quando amanhecer, pois o sobretensor deixa que a tensão flua normalmente, só entrando em cortes momentâneos se houver tensões que ultrapassem às especificadas da AMPOLA, ou seja, aos ± 240 V.<B> '' PHOTO-TRANSISTOR AMPOULES WITH SURFACES FOR LUMINAIRES '' <D>. The present utility model features a new drive system for luminaires, through a photo-transistorized circuit using a photo-transistor instead of a photo-cell, in addition to having an automatic over-voltage system that aims to protect the LAMP from higher than nominal voltages, plus ± 10% due to atmospheric discharges, sparks and other discharges, and this AMPOLA when connected to the mains works normally, causing the luminaire to rise when it gets dark and goes out when dawn, as the overvoltage allows the voltage to flow normally, only going into momentary cuts if there are voltages that exceed those specified by AMPOLA, that is, ± 240 V.
