Development of solid state illumination for parking lot application in reducing energy consumption

Nowadays, the development and improvement of solid state lighting (SSL) technology is accelerating to enhance its light output. Today, solid state lighting sources can be found in many applications that requiring colored (monochromatic) light, such as exit signs, traffic signals, and automobile brake lights. In the recent past, technological breakthroughs have started to establish SSL sources of white light. As investment leads to technology improvements as well as reductions in manufacturing costs, SSL may start to compete for market share with conventional light sources, such as incandescent, fluorescent and high intensity discharge (HID) lamps. This paper presents the potential of LED luminaries for outdoor lighting and focusing for parking lot application. A prototype model of parking lot LED lamp is constructed complete with the LED driver and the main objective is to achieve 20 percent energy saving compared the conventional parking lot lamp. The comparison is made between 100 Watt High Pressure Sodium Vapor (HPSV) parking lot lamp and the proposed LED lamp. The result obtained shows that it has a great potential the LED lamp will replace today’s lighting with this promising technology
