Led street light with special shape design of the led street lamp light application on the street lamps and lanterns, can make the lamps and lanterns of light Angle deviation, improve the utilization rate of the side of the road lighting; According to the aspect ratio of rectangle can produce the aspect ratio of 2:1 flare, so will not appear between adjacent light shadow, can form a bright light on the road light evenly, so more in line with the current traffic road lighting design. Don't need to improve the road lights led light pole height can meet the illuminate of enough wide range, but also improve the efficiency of the lighting lamps and lanterns, reduces the road lighting power density, and thus truly achieve energy saving and environmental protection with high power led street light used for road lighting, led street light light light color rendering index can reach more than 80, more close to natural light, the eye in this case are more likely to identify things, is good for road safety; High pressure sodium lamp and color rendering index only 20 - 30. Traditional gas discharge lamp, such as high pressure sodium lamp is started from time to tome a preheating process, which wastes energy and is not conducive to the integration of control; Led lights because the essence of the difference in light source, there is no & other; The startup time & throughout; Problems, plus electric immediately to work properly, can be very convenient to realize integration of energy-saving control.
