There are 3 tunnels in Zhuhai Hengqin Municipal Project in Guangdong, among which the longest Hengqin Mountain Tunnel (Changlong Tunnel) is located in Dahengqin Mountain, Hengqin New District, Zhuhai, with a length of about 2320 meters. In 2019, the intelligent energy-saving transformation and upgrading of tunnel lighting will be started. In this project, the 0~10V dimming mode will be used to control the dimming of the enhanced lighting and basic lighting in the tunnel. The enhanced lighting in the entrance section, transition section and exit section will automatically adjust the output brightness according to the intensity of the light outside the tunnel, so that the brighter the tunnel is, the brighter the tunnel is. The darker the tunnel is, the darker the tunnel is. When the light inside the tunnel is insufficient, the automatic compensation will be made, The basic lighting is controlled regularly according to the traffic flow and time period, and the user is set with modes 1 to 4. The four scene modes can correspond to different needs in daily life, holidays, etc. Different modes correspond to different brightness. For example, the "mode 2" of the south hole in the above figure is enabled, the brightness of the fixed time 1 (0~3 o'clock at night) is 20%, and the brightness of the fixed time 2 (3~5 o'clock) is 40%, which is set according to the needs, saving energy, It also greatly improves the driver's safety.
The customer was far away in Zhuhai, Guangdong Province, but before choosing our Shanghai Dikong 0~10V dimmer module located in Shanghai, they did a lot of comparative tests. Most of the 0~10V dimmer modules in the industry have an output current of 20~50MA, which is not suitable for long distance. They are connected to a large number of lamps. The dimmer module developed and produced by our company can have an output of 200MA, and can be set and operated independently with display. It can be used independently, with higher reliability and safety, In addition, the shell is made of aluminum alloy with insulation treatment. Compared with ordinary plastic shell dimmer module, it has better heat dissipation and protection, and is very suitable for tunnel and other environments.
