Abstract

Lo sportello per un apparecchio di illuminazione è adatto in particolare per l'illuminazione di oggetti rettangolari. Esso presenta un elemento di supporto (10), applicabile all'apparecchio di illuminazione con un'apertura (12) per il passaggio della luce. Attorno all'apertura (12) di entrata della luce sono applicate quattro ante (14, 16, 18, 20), all'elemento di supporto (10), le quali delimitano un'apertura dello sportello che presenta sostanzialmente la forma di un trapezio isoscele.Figura 2.
