What are ground lamps？

Ground lamps, also known as buried lamps or hidden lamps, are lighting facilities embedded on the ground. Ground lamps illuminate the ground and vegetation on the ground, which can make the landscape more beautiful and pedestrians safer to walk. The ground lamp now uses LED energy-saving light source, the surface is polished stainless steel or aluminum alloy panel, with high-quality waterproof joints, silicone sealing ring, tempered glass, and have the advantages of waterproof, dustproof, anti-leakage and corrosion-resistant. In order to ensure smooth drainage, it is recommended that the lower part of the ground lamps be installed with gravel. At present, most ground lamps use LED as the light source, because the LED has a long service life, the using time can reach more than 100,000 hours, and the consumption voltage is low, which is very suitable for use in solar ground lamps. Especially now LED technology has achieved its important breakthrough, and its characteristics have been greatly improved in the past 5 years. At the same time, the price-performance ratio has also been greatly improved. In addition, LEDs are powered by low-voltage DC, and their light source control costs are low and will not adversely affect the performance of LEDs. It is very convenient to control the color and change the light distribution, so it is especially suitable for the application of solar lawn lights. However, the luminous efficiency of LEDs currently sold in the market can only reach 15lm/w, only 1/3 of the three-color primary color high-efficiency energy-saving lamps, and the luminous efficiency of the three-color primary color high-efficiency energy-saving lamps can reach 50 lm/w ~60lm/w.
