I. Overview Figure 1. LED lighting effect of Guangzhou White Swan Hotel The LED lighting renovation project on both sides of the Pearl River is the government project to meet the Guangzhou Asian Games. The design of the bright projects on both sides of the Pearl River is from Baietan to Weizhou Bridge. The design is based on the selection of the most representative boats and sails on the river. West to East is divided into five segments: "Eythant Night Moon" (Swan takes off, sails for the fleet), "Yangcheng Years" (reflecting memories of the old age of Yangcheng), "Old City and the Past" (reflecting reform and opening up) The new weather), "Litchi Minor" (reflecting the local culture of Guangzhou and the local culture), "Guangdong New Rhyme" (showing the modern Guangzhou and commercial atmosphere), and the warm white light of floodlights to express the era of historical architecture Feeling, showing the picture of "Thousands of sails marching into the air". Guangzhou White Swan Hotel LED lighting project as the starting point of the sail team, has become the crowning touch of the picture. The White Swan Hotel is one of dozens of projects in Leroy's use of high-power LED floodlights. Engineering-based design principles: economical and rational; energy-saving and environmentally friendly; safe and reliable; easy to install; easy to maintain. The design and selection principle of the luminaire: beautiful appearance; long life and reliability of the light source; waterproof and lightning protection; anti-vibration; small wind resistance; anti-corrosion and anti-aging materials; energy saving and environmental protection. Figure 2.

The problem of external control system wiring and decoder waterproofing is reduced, and the installation cost of the LED control system is low. 2, save installation costs, system installation and commissioning is convenient and fast, to ensure the quality of the LED system. structure: 1. Integrated heat dissipation structure design, which increases the heat dissipation area by 80% compared with the general structure design, ensuring LED Luminous efficiency and service life. 2. The sealing ring adopts imported anti-aging silicone rubber raw materials. 3. Installation method: The end cover triangular bracket screw is installed, which is convenient and quick to install, and improves the construction progress of the project. Third, the control system solution DCS-4000A main controller to DCS-403R signal converter connection signal uses super five types of dual-screen twisted pair, the maximum transmission distance is 100 meters; DCS-403R signal converter to the distance of the lamp is 6 meters; between the lamp and the lamp The distance is 6 meters. If it exceeds 6 meters, DCS-405 or DCS-430R+DCS-403T should be added. The power supply of the project is 36VDC. The 600W/36V switching power supply supplies power to the lamps. Each of the switching power supplies can load 22PCS lamps. The switch power supply needs to be divided into three outputs, and the three-way lamps are balanced. 3. The maximum number of series connected to the lamps is 10PCS. If the power is exceeded, the power cables must be re-routed. Figure 3. Light change effect of Guangzhou White Swan Hotel
