How to choose road lighting? Did you choose correctly?

Road lighting refers to the illumination provided for roads and their ancillary facilities. It is used to enhance the safety of vehicles driving and pedestrians walking at night, preventing traffic accidents. Properly designed, it can improve traffic conditions, reduce driver fatigue, increase road capacity, and effectively reduce traffic accidents.

其质量取决于：（1）路面照明的亮度。即有足够的强度以保证车辆驾驶员和行人能看清路面上的障碍物、行人、车辆和道路周围的情况。（2）路面照明的均匀性。即分布应大致均匀。（3）眩光干扰程度。即有效地控制眩光对车辆驾驶员和行人的有害影响。（4）照明的引导性。即根据路面状况进行适当的设置，使车辆驾驶员和行人能有效地获得前方道路的方向、倾斜度等信息，这对有许多弯道和交叉口的道路尤为重要。合理应用灯具，能防止眩光。

Good road lighting greatly helps urban construction and people's traffic safety.

First, good road lighting can reduce traffic accidents. Especially when driving at night on the road, vehicle drivers must drive cautiously; compared to daytime, they need to identify traffic hazards and risk areas faster in order to make correct decisions and respond appropriately according to the severity of the specific situation. On top of ensuring these conditions, it is the setting of lighting. Balanced light distribution and minimal glare determine a decisive difference; good lighting can greatly reduce the dangers of night driving.

Secondly, good road lighting can improve traffic efficiency. LED street lights can enhance road guidance while avoiding lumen depreciation issues. Moreover, LED road lights can be configured with the Internet of Things; the lighting changes according to traffic flow variations, providing necessary conditions for smooth driving and significantly improving traffic efficiency and the traffic environment.

Third, good road lighting can reduce the likelihood of crime. At night, especially on less-traveled paths, criminal activities are most likely to occur. With road lighting, evidence and witnesses are more easily discovered, greatly reducing the motivation for offenders and enhancing urban safety.

So how to choose road lighting luminaires?

First, select the LED luminaire. Since LED luminaires far surpass traditional luminaires in energy saving, lighting effects, and service life, and LED luminaires allow convenient adjustment of color temperature and output power, greatly enhancing the humanization of lighting. Additionally, LED luminaires are green environmental protection luminaires, significantly reducing environmental pollution.

Secondly, from the power supply perspective, it is divided into retrofitting old lights and installing new street lights. If the road being built is a major urban arterial road and the surrounding supporting facilities are complete, then new street lights can be installed. If it is a rural road or an area where grid electricity access is inconvenient, we can consider retrofitting old lights by replacing traditional street lights with solar street lights, which provide both illumination and ease of installation.

Finally, considering the price aspect, solar street lights have a higher initial investment compared to grid-connected street lights, but incur no ongoing costs. In contrast, grid-connected street lights require electricity payments. Compared to high-pressure sodium lamps, LED street lights also have a higher initial investment; however, due to their superior energy-saving rate and stability, they will demonstrate significant advantages in later operations.
