Why should halogen buried lights be replaced with LED buried lights?

Is the buried lamp safe, or will it burn people? The author took a thermometer last night and tested the buried lamps in many places, and found that the temperature of the LED buried lamp is generally not high, and the hand feels hot, but There is no hot feeling, and the temperature of halogen lamps is generally above 120°C, which may cause burns.

At present, there are generally two kinds of buried lights, one is cold light LED buried lights, and the other is halogen buried lights. The temperature of the former is not high when working, and it will not be burned when touched. The latter, as the lighting time increases, the surface temperature will increase.

       We have conducted temperature tests on the buried lights in many squares and department stores, and found that the temperature of the halogen buried lights exceeds 100 degrees Celsius, but it is rare to see that the owners have warnings or protective measures, which pose a safety hazard.
       At the gate of Times Square, the floor lamp is about 30 centimeters in diameter, and the surface of the lamp protrudes a few centimeters from the ground. There are no protective measures or warning words, and passers-by can easily touch it. At about 7 o'clock last night, although the buried lights were not turned on for a short time, the temperature reached about 138°C, which was close to the glass of the buried lights, and there was a burning sensation.
      The halogen spotlights in the hot spring park are also placed within the reach of people. Our tests show that the temperature reaches 146.8°C.
      However, the buried lights located in the square at the entrance of Times Department Store are much safer because they are LED buried lights. There is a children's play area at the entrance of the department store, and there are many children. The ground lamps on the square are parallel to the ground, with a diameter of about 15 cm. They are LED underground lamps, and the lights are not dazzling. The thermometer showed about 36.6°C, and it was only slightly hot to the touch. When we were testing, some children touched it curiously.
