Abstract
The invention relates to a lighting device (10) including a lighting source (12) and a light guide (14), the light guide including an inlet optical surface (20), configured to allow the entry of the light emitted by the light source illuminating the inlet optical surface, and an outlet optical surface (22), configured to allow the exit of the light from the light guide, characterized in that the light guide also includes at least two through-holes (30, 31) arranged passing through the inlet optical surface and the outlet optical surface.
Claims13
A lighting device comprising:
- a light source;
- and
- a light guide that is monobloc and substantially rectangular parallelepipedic in shape, the light guide comprising:
- an entry optical interface located in a first plane and configured to allow the entry of the light emitted by the light source illuminating the entry optical interface,
- an exit optical interface located in a second plane facing the first plane and configured to allow the light to exit from the light guide, and
- at least two through-holes disposed between the entry optical interface and the exit optical interface,
- wherein the at least two through-holes are V-shaped, and
- wherein the at least two through-holes are spatially arranged to enable a component of the light, entering the light guide substantially in the direction of the length of the light guide, to directly pass through the light guide between the at least two through-holes without reflection or being affected by the through-holes,
- wherein the points of the at least two V-shaped through-holes are oriented in the direction of the entry optical interface.
