Optical void pattern lighting arrangement
View Patent ↗A lighting arrangement system including a light source and an optical void pattern formed into a substrate. The optical void pattern is formed using a laser and includes voids configured to alter light paths of light rays emitted from the light source directed towards the void pattern. The light paths are altered to form a light ray emission arrangement emitted from the substrate.
1 . A light arrangement system for a vehicle headlamp, the system comprising:
an optical substrate;
an optical void pattern formed in the optical substrate by a laser directed towards the optical substrate, wherein the optical void pattern comprises a plurality of voids within the optical substrate that do not extend to any surface of the optical substrate; and
a light source directed towards the optical void pattern,
wherein the optical void pattern is configured to refract a light path of the light source to form a light ray emission pattern,
wherein the optical substrate and the light source are disposed in the vehicle headlamp to act as a lens and the light ray emission pattern is projected outwards from the vehicle headlamp.
2 . The system of claim 1 wherein the optical void pattern comprises a plurality of voids each having substantially different depths for altering the light path in different directions based on the different depths.
3 . The system of claim 1 wherein the laser is directed towards a first surface of the optical substrate.
4 . The system of claim 1 wherein the light ray emission pattern is projected away from the optical substrate.
5 . The system of claim 1 wherein the optical substrate is fabricated from polymethyl methacrylate.
6 . The system of claim 1 comprising fabricating the optical substrate from a polycarbonate material.
7 . The system of claim 1 wherein the optical substrate is substantially translucent.
8 . The system of claim 1 wherein the optical substrate is approximately 0.05 inches thick to approximately twelve inches thick.
9 . The system of claim 1 wherein the optical void pattern comprises a plurality of microfractures in the optical substrate.
10 . The system of claim 1 wherein the light ray emission pattern is offset at an angle away from the light source.
11 . The system of claim 1 wherein the optical void pattern is formed into a first surface and a second surface of the optical substrate.
12 . The system of claim 1 wherein the optical void pattern is configured to concentrate the light rays such that the light ray emission pattern becomes brighter.
13 . The system of claim 1 wherein the optical void pattern is configured to disperse the light rays such that the light ray emission pattern becomes dimmer.
