| (54) | Vehicle lighting device with an annular reflector, and relative improved reflector |
| (57) A vehicle lighting device (1), typically a headlamp or signal lamp, including a casing
(2); a light source (3) and a reflector (4) housed inside the casing; and a transparent
cover (5) closing the casing and positioned opposite the light source. The reflector
is defined by a ring (20) made of material pervious to light, and constituting an
internal-reflection lens. And the ring is bounded by a front surface (21) facing the
transparent cover and located inside the casing, on the opposite side to the light
source; by an inner lateral surface (22), e.g. defining a geometrical figure of revolution
having an axis of symmetry (A) defining an optical axis of the lighting device, along
which the light source is located; and by an outer lateral surface (23) which is concentric
with the inner lateral surface, defines with the inner lateral surface an interface
bounding the internal-reflection lens defined by the ring, and includes at least one
inclined surface (24) forming such an angle with the optical axis that the light rays
inside the internal-reflection lens defined by the ring (20) are reflected totally
onto the front surface (21). |
