An extensive review of existing standards for street lighting was initially conducted so we could meet them with our LED street light design. From this, theoretical 3D light distributions were mathematically modelled and analysed in a wide range of street lighting schemes.
The result of modelling was a ‘target’ ray distribution that could be used as a specification for a custom LED lens design
. After extensive research on the global market, the most appropriate LED for the job was chosen. Lens design was conducted iteratively using ray trace CAD software in parallel with work on the electronics, heatsink & ingress protection system.
With design integration, complete high-accuracy rapid prototype custom LED optics
were produced. Our initial prototype was reviewed as a success, and we immediately progressed to production tooling. Mass production rapidly followed in volumes of tens of thousands of units.
