Buried lamp temperature test analysis: LED lamp low temperature halogen lamp has a burn hazard

The ground lamp is not safe in the end, will it burn people? I took the thermometer last night and tested the ground lights in many places. I found that the temperature of the LED floor lamp is generally not high, and the hand feels hot, but there is no burning. However, the temperature of halogen lamps is generally above 120 °C, which is dangerous to burn people.

Wangfujing's floor lamp temperature is 36.6 °C, it will not feel hot when touched.

According to industry insiders, there are currently two kinds of floor lamps, one is a cold LED street light, and the other is a halogen lamp. The former does not have a high temperature during work, and it will not be burnt if touched. In the latter case, as the illumination time is lengthened, the surface temperature will rise.

The author selected the ground lamps of the Fuzhou Wusi Road Global Plaza and the Wufu Road Wangfujing Department Store for temperature testing. It was found that the temperature of the halogen ground lamp was more than one hundred degrees Celsius, but the owner's unit had warning or protective measures, which had potential safety hazards.

At the entrance of the Universal Square at Wusi Road, the ground lamp is about 30 cm in diameter, and the lamp surface protrudes a few centimeters from the ground. Without any protective measures or warning signs, passersby can easily touch it. At about 7 o'clock last night, although the ground light was turned on soon, but the temperature reached 138 ° C or so, close to the ground glass, there is a burning sensation.

The spotlights in the hot spring park are also placed within easy reach of the people. The test shows that the temperature reaches 146.8 °C.

However, the floor lamp at the entrance of Wangfujing Department Store is much safer because it is an LED floor lamp. The department store entrance is a children's play area, and there are many children. The floor lamp on the square is parallel to the ground and has a diameter of about 15 cm. It is an LED floor lamp. The light is not dazzling when viewed. The thermometer shows about 36.6 °C, and it feels just a little hot. When the author tested, there were children who curiously touched it.
