Abstract

A lighting fixture (LT, TL) with a built-in emergency lighting circuit, comprising a casing (B2, TE) made of a transparent and diffusing material, inside of which a first light source (S1) used for ordinary lighting is placed, said first light source (S1) being controlled by a first electronic ballast (A1) which is connected, through at least one electrical connector (T1), to a mains power source, characterized in that a second electronic ballast (A2), which supplies a second light source (S2), independent from said first light source (S1), located within said casing (B2, TE) and used for emergency lighting, is series-connected to the input conductors (F1, F2) of said first electronic ballast (A1), said second electronic ballast (A2) being electrically connected to at least one battery (B1) and to said second light source (S2) by means of respective pairs of conductors (F3, F4, F5, F6), so that said second electronic ballast (A2) is able to control said battery (B1) using the electric current flowing through said lighting fixture (LT, TL) and to control said second light source (S2) which is used only for emergency lighting.
