Abrégé

Light (30) for motor vehicles and the like provided with a lighting device (31) comprising a pair of power supply lines (42, 43) flowed through by a primary supplying current (I1), two or more lighting branches (34) each comprising one or more light sources (37) adapted for being flowed through by a secondary supplying current (I2i); and an electronic control circuit (33) configured to determine the secondary current (I2i) flowing through each lighting branch (34); limit the primary supplying current (I1) to a predetermined minimum value (I1M) when the secondary current (I2) flowing through at least one of said lighting branches (34) is lesser than a predetermined threshold current (Si); control the simultaneous transition of the light sources (37) from a pre-lighting state to a complete-lighting state, when each of the secondary currents (I2i) flowing through the lighting branches (34) is greater than or equal to the predetermined current threshold (Si).

Abrégé

A method for injection moulding of plastic -material lenticular bodies (1) for lights; of motor vehicles and similar, the method comprising the steps of coupling a punch half-mould (15) with a first matrix half-mould (13) so as to define, on the surface of the punch half -mould (15), a first closed cavity that copies in reverse the shape of a first plastic-material sheet (2); filling said first cavity with a first plastic polymer in a liquid state, injecting the first plastic polymer in the first cavity from an injection point located at said first segment of the peripheral edge (2a) of the first plastic-material sheet (2); and finally separating, after the first plastic polymer has solidified to form the first plastic -material sheet (2), the punch half- mould (15) from the first; matrix half -mould (13) maintaining the first plastic-material sheet (2) still on the surface of the punch half -mould (15).
