Abstract

A lighting device, particularly a motor vehicle light, having a primary reflector (2) composed of a hollow body that defines a pair of pointed elements (4, 5), which face opposite directions, between which a luminous source (1) is placed; and a secondary reflector composed of an elongated element (3) with steps (6), at whose centre the primary reflector (2) is placed with its relative pointed elements (4, 5) facing the steps (6).

Claims

1. A lighting device, particularly a motor vehicle light, comprising a luminous source (1), a primary reflector (2) and a secondary reflector (3), wherein:

the primary reflector (2) is composed of a hollow body that defines a pair of ellipsoid-shaped pointed elements (4,5), which face in opposite directions to each other, and between which a luminous source (1) is placed;

said luminous source consists of a filament lamp (1);

the secondary reflector is composed of an elongated element (3) with steps (6), by whose centre is placed said primary reflector (2) with said pointed elements (4,5) facing said steps (6).

2. Lighting device according to claim 1, wherein said pointed elements (4,5) of the primary reflector (2) are formed by respective slits (7) on the opposite side of said secondary reflector (6).

3. Lighting device according to claim 1, wherein said steps (6) of the secondary reflector (3) are arranged at different distances.

4. A lighting device according to claim 1, wherein said hollow body (2), which defines said pair of pointed elements (4,5), is composed of a first portion (2a) that is incorporated into said secondary reflector (3);

and of a second portion (2b) that can be detached from the device so that said filament lamp (1) is exposed.
