How street lights play a role in 'smart cities'

Since the beginning of the year, there has been a wave of smart city construction in China. Due to the rapid development of Internet and Internet of Things technology, people's demand for smart cities is constantly updated and expanded. Road lighting is an important part of the city, and it is bound to become one of the future urban infrastructure iteration trends. So how do you want to release great innovation in the construction of smart cities?

Now more and more lighting systems begin to use smart LEDs, and smart LEDs have started a different journey as lamps. Of course, energy saving and relatively long service life are the obvious advantages of smart LEDs, which also play a big role in their market acceptance. But lamps are extremely advanced lighting devices, including LEDs and MCUs with integrated RF receivers. Wireless devices connect the lights with each other to form a larger network, providing more advantages besides energy saving. From the perspective of outdoor lighting, LED street lamps are currently replacing most of the common street lamps. Commercial lighting can also be realized by LED technology. From the industrial field, LED street lamps have largely solved some of the traditional street lamps. Problems, such as: heat dissipation, power, light attenuation, etc.

The application of LED in the field of road lighting has developed rapidly, and it is gradually replacing the previous ordinary high-pressure sodium lamps and metal halide lamps. Although the development of high-power LED street lights is fast, there are still different degrees of low luminous lumens per watt, low secondary light utilization, low system luminous efficiency, fast luminous decay, short life, and color temperature deviation. A series of problems, such as different light colors and many driver failures. Among them, the main technical issues such as secondary optical design, heat dissipation and power driver system design are the key to improving luminous efficiency and prolonging life. The characteristic of the LED street lamp itself is that there is no light diffusion and unidirectional light, which can ensure the light efficiency. Moreover, the light decay is small, and the luminous decay is still less than% after using for more than a year, and it still reaches the standard of road lighting.

Urban smart lighting will also become the development trend of urban lighting due to its multiple advantages of combining cultural and artistic experience and functional lighting techniques. At the same time, the intelligent management of LED light sources and lighting facilities also actively responded to the national call for energy conservation, leading the wisdom upsurge.
