Street light circulating in the market today: high-pressure sodium lamp, made because of the quality and technical issues short-lived, generally less than 3000 hours, the best imported to Philips, 3000-4000 hours, the monomer LED life of 80,000 hours or more , the cluster becomes a large power LED, its life span 60,000 hours or more, and so was the best HPS circulation today more than 15 times the life, that is so, more than 15 high-pressure sodium lamp replacement, LED lights only replacement of a replacement cost is not live under the light source, and therefore maintenance costs and inconvenience caused is the most obvious comparison (due to special purpose lamps, replacement difficulties, to spend a certain amount of manpower. machine resources to complete the operation).
Traditional lamp requires a large power supply system. Large power type transformers are very dear. And the traditional lamp voltage can not be too much volatility, otherwise, it will seriously affect the life of the lamp. The LED lights use the drive module, no need for large transformers. Voltage fluctuations, LED lamp brightness unchanged. T220C350W12S12 can drive 12W LED operating at voltages from 180V to 260V change, the entire drive to achieve constant current driver. Ensures high power LED street lamp brightness. In addition, the drive has many protection functions, in exceptional circumstances, the reliability of the entire grid.
With high power LED decorative lighting and general lighting in widespread use, the power LED driver become increasingly important. Road lighting using high-power LED lighting will be the possibilities. Road lighting is to use the longest and largest power lights, street lights with LED lights will greatly reduce the city's electric power shortage, the national energy savings.
Because lights are cross-pluggable, made using only single-sided light-emitting LED manufacturing, but only in the security lamp alignment position does not affect the lighting effects. Streetlight power of 20W, 30W, 40W, 50W high-power LED manufacturing, long life, maintenance-free. As the LED power consumption, low voltage, current, install the cable cross-section is reduced accordingly, saving installation costs. Therefore, more and more areas have begun replacing LED lights, reducing energy costs and maintenance expenses.
