Wu's weather

The light bulb that is being energized is flickering repeatedly, which may be caused by a circuit fault:

When the line connection contact is poor, it will increase the resistance there, according to Q=I? Rt shows that the heat generated by current passing through this place will increase, and the resistance at the contact will increase with the increase of temperature, thus forming a gradual accumulation of electric heat, a vicious circle, and then leading to a fire.

Precautions for replacing light bulbs

1. When replacing the bulb, it is necessary to consider whether there is a difference between the bulb voltage and the power supply voltage. If bulbs with different voltages are connected to the power supply, they will not work normally or even burn out. Therefore, in the process of replacing the light bulb, we must see whether there is a difference between the voltage of the light bulb and the voltage of the power supply. Only when the voltage of the two is the same can the light bulb be used normally.

2. When replacing the LED ceiling lamp, it is necessary to remove the rectifier on the LED ceiling lamp and install a new rectifier, because the rectifier and the wick of the LED ceiling lamp are integrated. After installing a new rectifier, just fix the wick on the chassis. In addition, when replacing energy-saving lamps and incandescent bulbs, do not loosen your hands from the metal part at the bottom of the bulb to avoid danger.

3. In the process of replacing the spotlights on the ceiling, it is necessary to gently pull down the lampshade by hand to let the spring clip behind the spotlights unfold slowly, then hold down the spring by hand, and then let go after removing the spotlights to avoid injury. There is a driver in the white square box, which can be used by connecting the driver and the lamp.

4. When replacing a fluorescent lamp or LED lamp, you need to hold one end of the lamp by hand and push it to the other end, so that you can remove the lamp at this end and then remove the lamp at the other end in the same way. When installing, the positive and negative tubes should be installed backwards in the first five steps.
