With the advantages of energy saving, long life, environmentally
friendly characteristics, steadily enhancement of output flux, and
decreasing LED prices, green energy LED lighting systems will
gradually replace the traditional light sourced lighting systems. With
the fast growing development of advanced optical components,
freeform secondary LED optics can improve the light output and
increase it to the maximum required. In comparison with traditional
lighting, the efficiency can be increased by 50% and the energy
required is only one tenth. The aim of this project is to establish
a technological platform integrating innovative optics design, ultraprecision machining technology, precision measurement technology
and precision injection moulding for the development of advanced
freeform optics for LED illumination.
