At present, many ecological parks light up solar power plant buried lights on the grasslands at night, which can not only indicate direction but also have unique functions. However, how can people choose the same type of buried light source? Don't worry, just because I'm by your side and I can moderately grasp it!

The vast majority of underground lights use LED as the light source, with a long usable lifespan of over 100000 hours. The standard working voltage is low, making it suitable for use in underground lights in solar power plants. Especially, LED professional capabilities have already undergone significant improvements, and its characteristics have greatly improved in the past five years. Its characteristic price has also been significantly improved.

In addition, the LED is powered by an adjustable bottom voltage DC power supply system, which has a low cost of lamp source operation, making it possible to adjust the angle perspective and frequently switch the power supply. Moreover, it is not easy to have a negative impact on the characteristics of the LED. It can also be controlled to locally manipulate colors, transform the spread of light, and create dynamic illusions, making it more suitable for buried lights in solar power plants. However, LED has many of its original characteristics, and if not taken seriously during application, it can lead to some unnecessary adverse effects.

At present, the high luminous efficiency of LED sold in the market can only ensure 15lm/W, while the high luminous efficiency of three color and three primary color LED energy-saving lights can ensure 50-60lm/W. From a price perspective, the cost per meter of production and manufacturing at this stage is 0.022 yuan for three color and three primary color high-efficiency LED LED energy-saving lights (including electronic ballasts) in 2002 φ The price of a 5mm white LED is 1.9-3.00 yuan, and the cost per meter of production and manufacturing varies greatly at this stage. From the perspective of service life, the service life of three color, three primary color, high-efficiency LED, LED energy-saving lights (including electronic ballasts) can be guaranteed to be 6000h, and the service life of LED can be guaranteed to be above 100000h. From the surface layer, the service life of LED is dozens of times that of three color, three primary color, high-efficiency LED, LED energy-saving lights (including electronic ballasts), but the universality of high level is not so.
