High-quality indoor lighting with high 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%.
A year or two ago, large-scale LED indoor lighting was only a dream, and now the market test fully proves that the dream has been taken into reality. As the “Eleventh Five-Year†National Science and Technology Support Program project undertaker, Yunlong Technology holds a scientific concept of development, with a high sense of mission and responsibility, advancing with the times, seeking truth and innovation, and research and development of “international leading, domestic first†semiconductor LED high Quality indoor lighting has not lived up to the trust of the country and has made due contributions to the country's energy conservation and emission reduction. Not worthy of the industry leader, energy saving wonderful!
“Xiongguan Man Road is as iron-like as it is now.†Yunlong people will, as always, adhere to the principle of market-oriented, user-centered, energy-saving, independent innovation, and work hard, and walk in the forefront of the international industry to develop more energy-saving. More environmentally friendly and more stable LED products, contributing to the energy saving and emission reduction of all mankind!
Twisted-pair, cable to optical fiber, waveguide and other transmission media are conductive media, and electromagnetic wave in free space in the long distance propagation is non-conductive media transmission; Attenuation is therefore a complex function of distance and is influenced by the atmosphere around the Earth. The main factors affecting propagation attenuation are: propagation frequency band F, propagation distance L and electromagnetic wave rate C(close to the speed of light). Free space propagation loss of microwave segment signals such as satellites is about 36000 km from the ground. The beam diverges with distance. High-power klystrons can transmit signals up to kilowatts, while satellite transponders can only be powered by solar energy. The satellite's limited surface area makes it difficult to transmit hundreds of watts of downlink power. As a result, the ground station's received signal power is only microwatt level and includes a compensation effect of tens of decibels of the gain of the receiving and transmitting antennas.
