On December 4, 2017, the 110KV dedicated substation of the Hong Kong-Zhuhai-Macao Bridge artificial port island officially delivered electricity to the bridge for the first time. Electricity is the basis for the smooth progress of the project. The successful transmission of this section will prepare for the commissioning of the bridge section communication, monitoring, lighting, dehumidification and other systems.
After the bridge was lit, it was like a fire dragon going straight into the depths of the ocean. The night illumination of the bridge road is divided into two parts, which are divided into functional lighting and daily lighting. All of them are provided by Shanghai Sansi. Different LED lamps play different roles in different time periods. (Hong Kong-Zhuhai-Macao Bridge uses a number of top technologies)
Daily lighting
Shanghai Sansi Ceramic Thermal Modular LED Street Light
Shanghai Sansi Ceramic Modular LED Street Light bears the main lighting needs of the bridge at night. Thousands of LED street lights are distributed on both sides of the bridge. Several highlights are safe escort. (Sansi light source connector without cable connection technology)
Highlight 1: Ceramic heat dissipation Shanghai Sansi replaces the traditional PCB board with ceramic lamp body. The ceramic is beautiful and corrosion resistant, overcoming the contradiction between insulation and heat dissipation in LED street lamps, plus heat dissipation in the near-end convection, eliminating the heat island effect and avoiding the heat accumulation effect. Lamp life, to prevent non-ferrous metal pollution and leakage hazards.
Highlight 2: The main parts of the luminaire are sprayed with protective materials. The curved appearance surface weakens the salt spray, resists wind, salt spray and corrosion, and adapts to the harsh environment at sea.
Highlight 3: Equal brightness illumination instead of traditional illumination illumination, the illumination of the street lamp contrasts with the dark road surface, reducing the visibility and resolvability of the object. The Sansei-based uniform light distribution system, under the condition of uniform illumination, tries to improve the brightness uniformity, eliminate the zebra crossing effect, and ensure driving safety.
Bridge landscape lighting
RGB color searchlight
Shanghai Sansi installed RGB color-changing searchlights for the Hong Kong-Zhuhai-Macao Bridge. When the Hong Kong-Zhuhai-Macao Bridge Festival passes, it will adopt a color change mode to add fun and enjoyability, coupled with the majestic momentum of the Hong Kong-Zhuhai-Macao Bridge. Shocking people.
Inspection lighting
LED bulb
Shanghai Sansi also provides daily inspection and illumination LED bulbs for the Hong Kong-Zhuhai-Macao Bridge. It is double-layered and can withstand the harsh environment of marine salt spray, vibration, large temperature difference and typhoon thunderstorm.
The power transmission has a total of 4 10kV lines, including the Zhuhai-Australia Port Link Bridge, the Shallow Water Zone Non-Navigation Hole Bridge, the Kyushu Waterway Bridge, and the Jianghai Zhida Bridge. It is expected that the main bridge will be lighted after the power supply conditions in the west artificial island.
