LED Lights In The City Road Lighting Application Research

At present, the main light sources of street lamps are HID(high pressure sodium lampand metal halide lamp), both of whose wattages are hundreds or above. These light sourcesinvolve high power consumption, short life time and large maintenance workload. As a typeof ‘green light source’, light emitting diode (LED) is the trend of development in the futurelighting. In recent years, with LED lighting technology matures. Single LED power increases,the luminous efficiency and ultra-high brightness successful development of high-powerwhite LED, LED applications, from small power backlighting across to the high-powerfunctional lighting. LED street lights, which came into being, the rapid development andurban road lighting mainstream light source to replace HID lamps. But there are also a lot ofpeople think that LED street lights are still many problems, its practical application is not asgood as HID lamps.Factor proceed in this article from the basic photoelectric characteristics, cost analysis,HID lights and LED lights works, the production process, market conditions, the developmentof an in-depth understanding. HID lights come into contact with at work (such as FoshanOsram Foshan Lighting Co., Ltd.) and LED lights (such as country star power) samples,according to the national standard test methods, the use of spectroscopy HID lights and LEDstreet lamp luminous fluxmeasurement of the optical characteristics of the color rendering,color temperature, etc..Utilize the EVERFINE Optoelectronic Information Ltd HAAS-2000high accuracy andfast spectral radiometer and the CIS-2000thermostat integrating sphere, HID lights and LEDstreet lamp luminous flux measurement noticeable color, color temperature and lightcharacteristics. By contrast HID lights and LED light source characteristics, combined withthe characteristics of urban road lighting, optical and electrical properties, cost analysis,product standards, analysis HID lights and LED light source in urban road lightingapplications, LED light sourcedepth research in the field of urban road lighting applicationsdevelopment.In this paper, the contrast can be seen by the performance of the test and analysisproducts and comprehensive analysis and application comparison, LED lights have the abilityin urban road lighting applications instead of HID lights HID lights and LED light sourcecharacteristics.
