| titleOfInvention | Metalens-based traffic lights |
| abstract | The present disclosure relates to the technical field of traffic lights, and the present disclosure relates to metalens-based traffic lights. A metalens-based traffic light includes: a primary optical device comprising at least a light source and a metalens device and configured to emit collimated light; a secondary optical device positioned downstream of the primary optical device in the optical path and configured to The light is diffused and deflected; the super-lens device includes a first substrate and a first metasurface structure arranged on the first substrate, and the first metasurface structure includes a plurality of regularly arranged first nanostructure units. The traffic signal light based on the super-lens of the utility model utilizes a primary optical device composed of a super-lens device and a light source, which can reduce the thickness of the traffic signal light, save the space occupied, and improve the optical performance of the traffic signal light through the secondary optical device. Close-packing can be used in metalens-based LEDs to achieve grain-free uniform light emission that cannot be achieved in existing traffic lights. |
