USING DIAMONDS TO REDUCE THE COST OF CAR PARK LIGHTING

Good reflector design is the key to cost-effective use of light in car park lighting. Until recently, there have been very few developments in optical controller technology for car parks. Research by DW Windsor Ltd has indicated that it is ineffective to design one reflector to suit all car park needs, but that a reflector in which certain elements could be adjusted could satisfy all the major requirements. As a result of this research, the Diamond Optic was developed and patented; it is a four element reflector, each element of which can be adjusted independently to enable light to be directed as required. It is suitable for many designs and sizes of luminaires. It can be arranged to suit a wide range of lighting requirements that cannot be met by conventional refractors or street lighting reflectors. Its four individual beams, created by its independent elements, seamlessly blend to enable the cost-effective creation of a wide range of light distribution patterns. The Diamond Optic has lower installation cost and lower maintenance costs over a period of years. This article describes it, and illustrates its cost-efficiency by comparing two methods of lighting an actual car park. In the second method, use of the Diamond Optic reduced overall electricity usage for the same light by 50% and costs by over 75%.
