Common problems with a table lamp

The advent of light bulbs marks a fairly important step forward in the global economy. Present in most households, bringing light is an indispensable item to help ensure living light for everyone.

But during the operation, when the bulb can encounter minor errors, you can learn how to fix the bulb at home. Here are a few common problems encountered when you use a table lamp.

The main cause of this phenomenon is due to a loose starter or improper display. The way to fix the bulb, in this case, is very easy, you just need to tighten the starter bulb to light up again.

If the display doesn’t fit or is burnt you should replace it so that its performance is equal.

Either due to a loose connection. This is one of the most common causes of flickering lights.

Lamp life is beyond the permitted limit, which means that the lamp life is 50,000 hours, the brightness of the bulb will decrease after that time.

If the light bulb of your house has just been bought, it is because the grid is overloaded. Due to the sudden increase in electricity demand in the area during peak hours.

For this, you only need to use a voltage stabilizer to ensure a stable power supply. Another cause of light bulbs is unevenly bright. Due to oxidized conductors and lamp holders, the lamp reduces brightness.

Compared with Halogen bulbs or old incandescent bulbs, LEDs have a longer lifespan. The lifespan of LED bulbs can be up to 25,000 hours – which is more than 20 years if you use them 3 hours/day.

However, due to incidents, the estimated lamp life may not be achieved. According to many industry experts, one of the most common reasons for lamps to burn is to place the bulb in the circuit and accessories used for the old bulbs before.

Compared to traditional lamps, current lamps are designed to consume a relatively low amount of heat they generate.

However, they can be destroyed by high amounts of heat, often in contact. If we put the lamp closer to devices with a much higher power, in an attached accessory device, the chance of the lamp failing early is very high.

  • Use poor quality bulbs: On the market today there are thousands of bulbs of different brands. With diverse designs, types, and quality. If you are not knowledgeable in this field, it is easy to buy fake, poor quality goods.
    *These bulbs are made of poor quality materials, making them very flammable.
    *Therefore, you should find and buy reputable bulb manufacturers to ensure quality.
  • Due to the unstable power supply: The power supply is not stable, fluctuating up and down, affecting the life of the ball. The stable power source for the most durable bulb to use is 180v to 220v. If the power source in your area is not stable. You should use a voltage stabilizer to make the electrical equipment in the home more durable.
  • Environmental agents: The humidity of the surrounding environment affects the life of the bulb greatly. And the bulb is installed in a high-temperature place, when operating, the temperature cannot be dissipated, affecting the driver.

You need to install the lamp in dry places that easily dissipate heat for maximum lamp durability.

In the process of using the power lines and switches are loose, corrosion gradually deteriorates. The reason the switch cannot be used is that the blade is in poor contact with the circuit.

In this case, it is necessary to use a bamboo stick to dab a little lubricating oil on the switch’s reed.

If the socket is loose, we use small silicone glue to the loose part, keep it for a few minutes, this phenomenon will be overcome.

Micro and motherboard are the two main parts of the light bulb, if these 2 parts have problems, you only have to call a repairman to replace and fix it for you.

Some light switches allow a small amount of electricity to pass through electrical equipment, even when turned off. With traditional bulbs, it is very difficult for this small amount of electricity to make them glow, because the amperage is not enough.

However, LED bulbs are so low powered that a small amount of “leaking” electricity like this can be enough to make them glow.

The arbitrary choice of lamps to install can easily destroy the look of the whole house, it is impossible for a small apartment to be fitted with classic chandeliers, or not for a big house to fit only small wall lights.

On the other hand, the color of the house, as well as the color of the furniture, must be the same color as everything in the house, you should not be greedy to use too many colors that will make the house become confusing, even Lice can affect the refractive error of the eye.

Your light, although a small factor, also contributes to the appearance of the whole house. Choosing the right lamp for space and living habits is really necessary for you.

The lighting rule consists of 3 elements: general lighting, spotlighting, and work lighting. However, few people will know and apply this rule correctly.

Spotlighting is the type of lighting that creates an accent, based on the ambient light of the room by using lamps with narrow beam angles, the light is focused only on one point, it attracts attention. into an object such as pictures, plants, shelves.

General lighting is the primary light source for a given area, it is the foundation of all the lighting of a room. The general lighting will give you the ability to observe, move comfortably and securely throughout the entire space of the room. General lighting will come from lamps such as ceiling-mounted, chandeliers, large table lamps.

Lighting for work is the type of light serving the working needs of humans such as: studying, reading, working, cooking… so it is necessary to reduce glare and have enough light to prevent eyes. stress.

To choose the right and standard lighting, it is necessary to rely on the following factors to decide: purpose, time, work habits, and even age of the user.

5 Frequently asked questions

When embarking on repairing something, you must also have many questions. Through research and inquiry, we want to help you answer some of the basic questions below. Hope it helps you.

The cost of rewinding a table lamp depends on the type, size, and construction of the lamp. For example, antique lamps are a bit more complex than recently manufactured lamps, so rewinding can be more expensive.

And it also depends on your workmanship and whether the electrician has the right cables, and bulbs in stock for your particular lamp.

The time to perform tests and repairs may vary depending on the error. You can expect to pay about $ 30 to $ 45 per hour for a table that is wrapped by an electrician.

Depending on the age of the lamp, you may need to replace it with a new cord. This is because different bulbs can have different wiring.

Electrical faults can happen and can happen at any time. If you have a lamp that has not been maintained for a long time, chances are that the insulation rubber has worn out and needs replacing. Electrical faults can also happen like wire burnout and make them no longer safe, replace them.

Or when you move into a new home, I think you also have to reexamine the bulbs and re-wrap them as needed.

To rewind a table lamp, you need to go through the following steps:

  • Step 1: Remove the old outlet.
  • Step 2: You cut with the ends of the two connectors, then use scissors or a knife to lightly cut around the end of the wire to remove the outer shell to get the copper core (cut to the core about 3cm). More simply, you equip yourself with automatic wire plucking pliers, making it easier to peel off the shell quickly and not break the wire core.
  • Step 3: Next, you twist the ends of the copper core wire, connect the two ends of the broken wire together by bringing the two pieces of copper core wrapped in “L” shape, twisted together, and then twisted back, connecting Then check the strength of the joint.
  • Step 4: Finally, use insulation tape to separately wrap the two connecting wires to insulate and not short.
