Common things about LED underground lights that you should know

LED underground lights are now widely used in parks, lawns, plazas, courtyards, flower beds, and pedestrian street decorations. However, in the early practical applications, LED underground lights showed various problems. The biggest problem is the waterproof problem.

At first, it was believed that the LED underground lights does not need to be IP68 rated waterproof because it is not as long as the LED underwater light in the underwater environment and under the pressure of water. But in fact, LED buried lights need to solve the waterproof problem. In practical applications, LED buried lights are now on the ground or in the soil, in addition to dealing with rainy days or water immersion, but also to deal with the problem of thermal expansion and contraction.To solve the waterproof problem of LED underground lights, we must start from several aspects.

  1. Housing: Die-cast aluminum housing is a common choice, and the die-cast aluminum housing is waterproof. However, due to the different casting methods, the outer shell is dense and dense (molecular density) is different. When the outer shell is soaked to a certain extent, the water will not cause water molecules to immerse in a short period of time. However, when the lamp shell is buried in the soil for a long time under the influence of the hot and cold suction force, the water will slowly infiltrate into the lamp housing. Therefore, we recommend a thickness of the outer casing of more than 2.5mm and die-cast with a sufficient die casting machine.


  1. Glass surface: Tempered glass is the best choice, and the thickness should not be too thin. Avoid the breakage of water due to the stress of thermal expansion and contraction and the knocking of foreign objects.
  1. Heat dissipation and ventilation: The LED underground lights have high heat and needs good heat dissipation and ventilation. It avoids the temperature difference between the inside and outside of the lamp is too large, water vapor appears, and the sudden cooling heat causes the bad lamp. The direct or indirect contact area of the lamp housing with the LED is more than 80%, and an air respirator or a heat sink may be added.
  1. Pre-embedded parts: The embedded parts should be as high as possible, and enough water will be immersed in the lamp body.
  2. Glue: The glue is filled under the lamp body, and the thermal silica gel is filled on the lamp body.
