An impressive 520 LED-based streetlamps with 37,440 Golden DRAGON Plus LEDs (cool white) were installed along the road from Wonju interchange to South Wonju interchange, and replaced traditional MH 250W and 400W street lamps.
GALED anticipates that the LED-based street lamps can save 48% power consumption, while the total cost of ownership can further reduce because of the exceptional 50,000 hour lifetime of Golden DRAGON Plus LEDs, minimizing maintenance and replacement costs.
The Korea government plans to replace all incandescent light bulbs at public facilities with more energy efficient LED bulbs by 2012. President Lee Myung-bak has personally stressed the importance of energy conservation in today's economic environment, instructing local Korea government chiefs to focus on ways to Reduce energy consumption in their regions.
Golden DRAGON Plus LEDs offer full-color spectrum brightness, consume 80% less electricity than incandescent lamps, and can last more than to 50,000 hours. The longer service intervals and the robust nature also attribute to LED-based street lighting by reducing maintenance costs.
The availability of cool and warm white LEDs with excellent color rendering offers the flexibility to adjust the color temperature to specific street lighting applications.
Incremental encoders provide speed, direction and relative position feedback by generating a stream of binary pulses proportional to the rotation of a motor or driven shaft. Lander offers both optical and magnetic incremental encoders in 4 mounting options: shafted with coupling, hollow-shaft, hub-shaft or bearingless. Single channel incremental encoders can measure speed which dual channel or quadrature encoders (AB) can interpret direction based on the phase relationship between the 2 channels. Indexed quadrature encoders (ABZ) are also available for homing location are startup.
