In cold winter, adjusting the brightness of street lights does not require going outdoors, but can be achieved by sitting in the monitoring center; In large shopping malls and parking lots, smartphones can tell you where the restroom is and where the car is parked... These can be achieved through the installation of LED lighting systems for navigation and positioning. On January 6th, the Cross Strait Cold Region Semiconductor Lighting Technology Forum held extensive discussions on topics such as research and development hotspots and latest achievements in cold region semiconductor lighting technology.

According to the Harbin Science and Technology Bureau, currently, Harbin has applied 150000 LED lamps in fields such as ice and snow landscapes, road lighting, and indoor lighting, with a total investment of nearly 200 million yuan. This has effectively integrated ice and snow culture and art, characteristic architectural art, and semiconductor lighting, creating a city impression of a dreamy ice city and a beautiful river city. According to Fan Qingwei, director of Harbin Lighting Testing Center, Harbin has applied 150000 power LED lamps in areas such as ice and snow landscapes, road lighting, and indoor lighting, with a total investment of nearly 200 million yuan.

Is LED lighting suitable for use in low temperature weather? Therefore, the Harbin Lighting Testing Center conducted cold reliability tests in three cities: Mohe, Jiagedaqi, and Harbin. The results of a 12 month cold lighting test were first announced on the forum. LED lights can still be used normally in extremely cold weather with temperatures below -40 degrees Celsius, saving more than 60% energy compared to traditional high-pressure sodium lamps. The application performance is relatively stable, and the maintenance rate is low. Intelligent street lights can remotely control which street lights are dim, and there will always be enthusiastic citizens calling to inform the electricity department. In Taiwan, there is no need to trouble citizens. Street light management units can receive warnings as soon as possible through a unified monitoring center, and computers can immediately report the cause of the malfunction and achieve remote control.
