独立照明是一种提高能见度的方法,常常在复杂的道路立交桥和平面交叉路口等关键地段采用。因在许多场合,这些地段常带来视力适应问题,易发生危险,导致交通事故的增加。根据高杆配光方式,高杆照明可消除由于不均匀独立照明场所而产生的许多问题,它是一般独立照明装置的典型范例。高杆照明的优越性常体现在一次性投资、安全性、美观性和维护费用等方面。 Stand-alone lighting is a way to increase visibility, and is often used in critical areas such as complicated overpasses and plane intersections. Because on many occasions, these areas often bring about vision adaptation problems, are prone to danger and lead to increased traffic accidents. According to the high-rod light distribution method, high-pole lighting can eliminate many problems due to non-uniform independent lighting places, and it is a typical example of general independent lighting devices. The advantages of high pole lighting are often reflected in one-time investment, safety, aesthetics and maintenance costs.
