Innovative long range projector sector lights
Back in 1972 a new innovative design for a sector light was designed in New Zealand. It provided far greater resolution of the sector boundaries than had previously been possible. This design was originally developed by Norman Rumsey, Head of Optics at the Department of Scientific and Industrial Research (DSIR), Physics and Engineering Laboratory (PEL) in New Zealand.
Vega Industries successfully refined and enhanced the design concept and developed a commercially viable sector light product. The first light was designed to mark the entrance to Paremata Harbour North of Wellington, the capital city of New Zealand. A tall cliff at Goat Point meant that there was insufficient resolution for a traditional 2-station leading light system. This early PEL light (small images above) was a very modest device compared to today’s sophisticated instruments, but it did the job required and remained in service for more than 30 years before eventually being upgraded to a more modern PEL.
