The high-quality indoor lighting of semiconductor LEDs has attracted much attention in Anhui Luogang Airport, Baida Group Shopping Center, Baidu Group Hefei Gulou Commercial Building, Qingyun Clothing Shopping Mall, Anhui First Department Store Capital, Hefei Yuanyi Times Square, etc. After over a year of large-scale application and monitoring, the large venues have enjoyed good results. Three data are obtained: 1. The functional effect exceeds the original value; 2. The energy saving rate exceeds 70%; 3. The failure rate is less than 1%.
Hefei Luogang International Airport is an important aviation hub connecting Anhui Province to the east and west and coastal developed areas. Luogang Airport has always been committed to the operation concept of low carbon, energy saving and environmental protection. In 1996, the 4D standard for modern airport was expanded to design an annual passenger throughput of 1.5 million passengers. In April 2009, the expansion of the terminal building was completed. The total area of ​​the airport terminal building reached 18,780 square meters. The waiting hall has 2 floors and the terminal building is 9.5 meters high. A total of 4,500 ç› (two energy-saving lamps per swell plus two ballasts) lamps are used for conventional lamps, with a total power of 220 kW, 18 hours of lighting per day, 3969 kWh of electricity per day, and an annual power consumption of 1,448,600 kWh. A very large energy consumption; in order to effectively replace traditional lighting methods, the airport-related management departments are upset. After learning the news, Yunlong Company took the initiative to find the relevant leaders of Luogang Airport and promised that if Luogang Airport selected Yunlong LED lighting system, it would save at least 70% of the electricity for the airport and ensure the quality and stability of the products. Ensure that the lighting is stable to ensure safe operation of the airport. After several rounds of negotiations, the cooperation was formally confirmed. After nearly three months of installation and repeated debugging, after one year of application and testing, the daily power consumption is 972 degrees, the annual power consumption is 354,800 kWh, and the power saving rate is 76%. Yunlong fulfills the promise, not only that, but also The application of Yunlong LED lighting system, the overall lighting effect is particularly lining the international quality of Luogang Airport.
Anhui Baida Shopping Center is invested and built by China's Top 500 Enterprises. The Top 100 Shopping Center is located in the bustling Huaihe Road Commercial Center. Can Baida be the most brilliant “Pearl†of Huaihe Road Business? The design is very important. After Yunlong won the bid for the Baida Shopping Center project, according to the project positioning and characteristics, the theme of soft, comfortable, prosperous and bright lighting was designed. After nearly three months, the project was installed, dispatched and delivered.
Today's Baida Shopping Center is undoubtedly the most iconic building on Huaihe Road, and it is the focus of attention. The building has 6 floors and a total of 12,000 watts (two 18W energy-saving lamps plus two ballasts per turn), with a total power of 600kW. Working 13 hours a day, the daily power consumption is 7800 degrees, and the annual power consumption is 2.847 million degrees. Now it is replaced by a semiconductor functional lighting fixture with a total power of 144kW, a daily power consumption of 1,872 degrees, and an annual power consumption of 683,300 degrees.
In a blink of an eye, Baida Shopping Center has achieved an annual economic savings of 2.163 million kWh through the application of Anhui Yunlong Technology Lighting System, which has achieved good economic benefits in terms of energy efficiency and cost control.
The Bluetooth wireless speaker is the terminal of the entire audio system, to convert the audio energy into corresponding sound energy and radiate it into the space. Bluetooth speakers usually consist of speaker, crossover, cabinet, sound absorbing materials and so on. Bluetooth speaker is a device that converts audio signal into sound. In general, it means that the main body of the speaker or the subwoofer box has its own power amplifier. After the audio signal is amplified, the sound is played back by the speaker itself, making the sound louder.
Advantages:
1: Perfect support for the tablet and mobile phone. The transmission is stable. the distance is generally 10 meters.
2: Miniaturization, fashion, and versatility.
3: The sound quality is delicate and soft. The appearance is more delicate and beautiful.
The sound pressure level of the sound is not too high, and the power received is relatively small.
