Causes and solutions of human induction lamp always on.

Dao no longer uses switches to control the lighting, but often uses human induction lamp to control the switch of the lights through induction. What is the reason why the human induction lamp is always on? Many car owners have encountered it, let's take a look!

There is a problem or interference with the sensing component.

There may be something wrong with the sensor assembly or interference, such as temperature change and voltage instability, or there may be something wrong with the internal structure, such as the failure of the photosensitive resistor. The light bulb used at the same time does not match the induction switch, and the wiring of the lamp is wrong, which will cause the lamp to stay on all the time.

Choose the right light bulb

Usually, the light bulbs that can be used will be marked on the back of induction lamp, and we can choose products according to the instructions. If you need to use other bulbs, you should contact the merchant and ask if you can replace the original bulbs. However, it is necessary to replace the induction switch with a compatible switch to ensure the normal use of the human induction lamp.

Photosensitive resistor does not work.

The working state of human induction lamp is often used under the condition that the surrounding environment is unclear and the light is weak. When there is enough light during the day, the value of the internal photosensitive resistor will change accordingly, so that the induction lamp of the human body will not be affected and stop working. If the photoresistor doesn't work, the induction lamp will stay on. In this case, you can first test it with a multimeter to see if the value is normal, and then see if the resistance hole on the lamp shell is blocked.

Peripheral interference

In addition, when the infrared rays emitted by our body irradiate the lamp sensor, it will generate charges and release them to the outside. Then a control signal will be generated in the lamp to light the lamp. After a period of time, the human body induction lamp will stop working again. So, if the induction lamp lights up all the time, we need to see if there is any interference around, and then deal with it.

Night convenience

However, induction lamp has brought great convenience to our life, especially to families with babies and old people, who often have to get up at night. Installing this kind of lamp can avoid the problem of finding a switch to turn on the light in the dark. Moreover, the light source of this kind of lamps is soft, which will not affect people's eyes and has a wide installation range.
