陶瓷金卤灯还是LED？
1、LED光源：
1, LED light source:
LED灯是近年兴起的新型半导体材料光源，LED就是发光二极管。LED产品的知识产权主要在美国，发光芯片的产能主要在台湾。
LED lamp is a new type of semiconductor material light source which has been developed in recent years, and LED is the light emitting diode. The intellectual property rights of LED products are mainly in the United States, and the production capacity of luminescent chips is mainly in Taiwan.
LED发光二极管主要由PN结芯片、电极和光学系统组成。LED灯发光是点光源（其它光源为面光源），其发光效率较高，色温也高，目前用于室内4米以下空间照明已经较为普及。但由于LED芯片物理特性导致其对温度敏感，随着温升而光效下降，容易光衰；且其照度不均匀，色温高而光穿透效果差，并产生较严重眩光（光污染），因此不适合多雨多雾多霾地域的道路照明，也不利于夜间交通安全；LED路灯比较现有的高压钠灯+电感镇流器组合，实际节电率在50%左右；LED路灯价格较昂贵，每盏灯价位在3200元~7500元之间，质量较好的品牌高达万元；大部分LED灯为整体模块封装，维修与更换不便；迄今LED路灯还没有超过四年的稳定运行记录。上述问题致使各地路灯管理部门大都不愿使用LED光源路灯。
The LED light emitting diode is mainly composed of PN junction chip, electrode and optical system. The LED light is a point light source (other light source is a surface light source). Its luminous efficiency is high and its color temperature is high. At present, indoor lighting for 4 meters below is popular. But because of the physical characteristics of the LED chip which is sensitive to temperature, with temperature and light efficiency decreased, and its easy to decay; uneven illumination, high temperature and light penetration effect is poor, and serious glare (light pollution), it is not suitable for road lighting in the rainy and foggy haze region, is not conducive to traffic safety LED street at night; compared with the existing high-pressure sodium lamp inductance ballast + combination, the actual saving rate at about 50% LED street; the price more expensive, each lamp price between 3200 yuan ~7500 yuan, a good quality brand as high as 10000 yuan; most of the LED lights for the whole package module, maintenance and replacement of inconvenience; stable operation record so far LED street is no more than four years. The above problems caused most street lamp management departments not to use LED light source street lamps.
2014年4月15日，在江苏扬州的高邮市举行国家级2014（第十届）中国道路照明论坛上，中国建筑科学研究院光环境与照明研究中心王书晓高工在大会主题报告中指出，他受权领导的团队对全国10条采用LED光源照明的城市主干道和19条采用LED光源照明的次干道进行了长达18个月的持续跟踪监测。监测结论是：主干道采用LED光源的合格率只有10%，次干道合格率只有5%！
In April 15, 2014, Jiangsu Yangzhou, Gaoyou city held 2014 national (tenth) Chinese Road Lighting Forum, Chinese Academy of building light environment and lighting engineering research center Wang Shuxiao in the theme of the conference report, he authorized the leadership team for as long as 18 months of continuous monitoring on the national 10 by LED lighting the city roads and 19 roads with LED illumination. The result of the monitoring is that the qualified rate of the main road using LED light source is only 10%, and the pass rate of the secondary road is only 5%.
