LED light source (LED refers to Light Emitting Diode) is a light emitting diode light source. This type of light source has the advantages of small size, long life, high efficiency, and can be continuously used for up to 100000 hours. In the future, LED light sources will also become the mainstream application in the lighting field.
After decades of technological improvement, LED's luminous efficiency has been greatly improved. The lighting efficiency of incandescent lamps and halogen tungsten lamps is 12-24 lumens/watt, fluorescent lamps are 50-70 lumens/watt, and sodium lamps are 90-140 lumens/watt. Most of the power consumption becomes heat loss. LED light efficiency will be improved to reach 50 to 200 lumens per watt, and its light has good monochromaticity, narrow spectrum, and can directly emit colored visible light without filtering. Countries around the world are stepping up research on improving the luminous efficiency of LEDs, and their luminous efficiency will be significantly improved in the near future.

China's e-commerce is changing the urban landscape. "Beishang Guangshen" is becoming "Beishang Shenhang". The decline of traditional trade will pull Guangzhou down, and the rise of cross-border e-commerce will help Hangzhou rise. In the future, the urban pattern of China should be "regulation in Beijing+financial operation in Shanghai+intelligent technology in Shenzhen+e-commerce in Hangzhou".

LED wall washing lamps, as the name suggests, let the lights wash the walls like water, mainly used for architectural decoration and lighting, as well as for outlining the outline of large buildings.
LED spotlights are spotlights that use light emitting diodes as light sources. Traditional spotlights mostly use halogen lamps, which have low luminous efficiency, relatively power consumption, elevated ambient temperature, and short service life. LED light sources are far superior to traditional lighting fixtures in terms of luminous principles, energy conservation, and environmental protection.
