Posted by ff on December 4th, 2020

As a necessary lighting appliance in life, led bulbs often need to be replaced. As a life expert, how can you not install bulbs? Now let’s talk about how to install led bulbs. Those who don’t know how to install bulbs themselves should learn quickly.

1. Prepare a led light bulb, the power is 40W for general household use, and confirm the connection method of the light bulb at home. Commonly used are screw and socket. The difference between the screw socket and the socket of the bulb is because the humidity in some places in China is too high, the screw socket is easy to rust and the bulb cannot be screwed off. This is not easy for sockets. Therefore, the use of southern socket bulbs should be more popular.

2. Although the installation of light bulbs is not a major project, the installation process should not be careless, otherwise safety problems are prone to occur. When installing the light bulb, it is absolutely not allowed to "fold a big chair over a small chair", and the consequences will be disastrous once it falls. It is recommended to use a herringbone ladder, which is safer, and it is better to have a helper to stabilize the ladder to prevent accidents.

3. Find the entry switch at home and open the switch. Because the light bulb switch only turns off one line of electricity (generally 2 sets of electricity at home, live wire and neutral wire), although the light bulb does not light up, it is very likely to be charged. Pulling off the main switch is to ensure safety.

4. There is a red wire on the lamp holder as the live wire and a blue wire as the neutral wire. When connecting the lamp holder, use a test pen to check whether the two wires have electricity. After confirming that there is no electricity, connect the live wire and the lamp holder wire. , And wrap the insulating cloth, then connect the neutral wire to the other wire of the lamp cap, and wrap the insulating cloth.

5. Climb up the ladder to change the bulb, turn on the flashlight, hold the bulb holder with one hand, and the broken bulb with the other, apply a counterclockwise force with the left hand and clockwise with the right hand in advance, the attention can be tentative, because some bulbs Over time, it may be broken if you use strong force, then slowly increase the force, and you can screw it off. Then replace it with a new light bulb and tighten it.

6. Due to energy conservation and environmental protection reasons, the country has banned the sale and production of incandescent lamps. However, this experience sharing does not affect his use, because the connection of incandescent lamps and energy-saving lamps is the same, but it should be noted that do not hold the lamp tube when installing the energy-saving lamp, the lamp tube is easy to break, other steps are the same as incandescent The installation of the lamp is the same.

Precautions for installing the led light bulb

1. Insulation should be done well in humid environment, such as bathroom and kitchen, if insulation is not done well, it is easy to short circuit.

2. The light bulb is made of glass. When installing the hanger, an iron expansion bolt (iron expansion pin) must be used. Do not punch a hole first, and then drive a wooden wedge to tighten the screw. This method is only suitable for The horizontal fixing of the wall is not suitable for the top surface. It is also not recommended to use plastic expansion tubes, because plastic expansion tubes will deteriorate over time.

3. Prepare some No. 6 screw nuts in advance, because you will encounter such a situation when installing the lights: when installing the chassis, because the original screw nut is sealed at one end, it can’t be screwed to a certain extent. In this case, you can screw a No. 6 screw first and increase the force, and then screw the original screw, which is beautiful and prevents the chassis from not being able to completely match the top surface.
