220В 1000Вт ЗЗЭВП III 1955 (или 1965), тепловой экран
Слюдяной. Он преграждает (точнее, значительно утрудняет) путь раскаленному конвекционному потоку газа, который поднимается со спирали. Это уменьшает нагрев цоколя лампы, что уменьшает вероятность его "отклеивания". Также металлические экраны препятствую ИК-излучению от спирали. Не знаю, дает этот же эффект слюда или нет.
