LED work light is an ideal lighting solution in the modern world. It has many outstanding advantages and has a lifespan of up to 50,000 hours. However, nothing is completely perfect. In the process of using, in addition to advantages, LEDs sometimes encounter some problems. If you want to know 6 common problems about LED lighting, this article will give you a more specific look and how to solve these problems.
#1. LED work Lights Stop Working
Do your LEDs claim a life of up to 50,000 hours in the advertisement, but suddenly stop working after using them for a year, months, or even just a few weeks or days?
This is indeed a problem, because there are many possible causes. Unless you are an LED expert or a professional electrician, it is not easy to find out the cause.
As we all know, LEDs do not “burn” (broken wires) like incandescent lamps, but only dim (reduce brightness). However, due to current and installed negative reasons, they may still burn other components (except LED chips).
The common reasons that cause the LED to stop working are: heating, screwing the lamp too tightly or placing the LED in an inappropriate circuit and accessory.
In addition, poor-quality capacitors, drivers and diodes are also the main factors that reduce the life of LED bulbs.
So how do we fix them?
When the LED suddenly stops working, the first thing you need to do is to check the circuit breaker. If there is no problem, turn off the power and check the internal parts of the lamp, such as capacitors, drivers, etc.
Reason 1. For poor quality capacitors or drivers: If possible, please replace it yourself or hire an electrician to help you. Or if they are too difficult to repair or replace, you can also replace the LED bulbs.
Reason 2. For inappropriate current or accessories: The best solution to prevent this is to replace all bulbs with new accessories at the same time, bundle them together, make them compatible with each other, and create a smooth and efficient system. This will greatly reduce the risk of excessive radiant heat, thereby improving light efficiency.
Reason 3. The bulb is screwed too tightly: If the copper vortex is bent, you need to turn off the power and bend it forward with needle-nose pliers (about 20 degrees from the bottom of the socket).
And in order to avoid similar situations, you need to pay attention to a few things after installing the bulb: Don’t screw the bulb too tight, and don’t screw it too fast, just turn it on until the light turns on, and then stop.
#2. Led work Light Not Change Color
Your LED light will not change color, it may be due to bad pin connection or wrong pin. Poor pin connections also include reverse connections or reverse polarity.
LED strip lights usually have two sides: one side is positively charged (indicated by a dash), and the other side is negatively charged (usually marked by the manufacturer’s logo).
The arrow on the connector should point to the plus sign on the bar light. If your LED strip light does not change color, it may have this reverse polarization problem. In this case, try to flip the light bar and reconnect it.
#3. LED work Lights Burn Out So Fast
Modern LED bulbs usually have an impressive lifespan, and if used properly, they can light up for many years.
However, if your bulb burns out before the advertised service life, even if you follow the installation instructions, this may be due to the following 4 reasons:
Reason 1: High voltage
The consumption voltage of the led is much lower than the voltage of the home power grid you use. Therefore, the LED always has an LED driver, which is responsible for converting the power supply from alternating current to direct current to obtain the voltage required for the operation of the LED chip.
If the LED lights in your house burn out quickly, this may be due to a sudden surge in voltage. When the voltage suddenly rises, the LED driver is not adjusted in time, causing the bulb to burn out, and even other electronic devices in the house are in a similar situation.
To solve this problem, you can ask an electrician to check the voltage at home, or you can contact the electrical supplier for help.
Reason 2: Bad connections
A bad connection will cause your LED to be damaged quickly. This may be due to the bulb being screwed too loosely or too tightly, the contact points are worn out, or a loose wire connection. When you encounter the above problems, you can fix it in the following ways:
For a loose bulb, you can tighten it so that the contact points are close together. If the bulb is screwed too tightly so that the socket label is depressed, you can fix it according to the instructions in the previous section.
If the contact points are worn or corroded, you can replace the socket or replace with a new fixture. If the problem is caused by a loose wire connection, you can ask an electrician to fix it, or fix it yourself if you can afford it.
Reason 3: Overheating
LEDs are particularly sensitive to temperature. It does not generate light by heating, but may overheat when used in incompatible fixtures. Generally, each type of lamp has one or several compatible bulbs, and no LED bulb can fit it.
In addition, the size of the installed bulb is inappropriate (too large or too small), compared with the fixture, even if the base is suitable, it will cause the lamp to overheat.
When the bulb is overheated and the radiator cannot work effectively, it will shorten the life of the lamp. In addition, the ambient temperature is also a factor that affects the durability of the lighting equipment.
This problem often occurs with embedded LED lights, because their taillights are designed to hide on the ceiling, causing heat to accumulate and may burn the bulbs.
To solve this problem, you need to find out which type of LED bulbs are compatible and the size of the lamp that fits you. For embedded LEDs, it is recommended to arrange vents on the ceiling. When the design needs to pay attention to this, use a gypsum ceiling. At the same time, make sure that your bulb has the best cooling system.
Reason 4: Low quality LED work bulb
If you check and find that the LED is not damaged due to the above-mentioned reasons, it is very likely that you have purchased a low-quality bulb. In order to ensure your interests, you should check the LED lamp warranty and contact the supplier as soon as possible.
#4. LED work Lights Gone Dim
There are many reasons that cause your LED lights to dim. Here I will give some typical reasons that many people often encounter.
4 reasons for the dimming of LED work lights and how to fix them
Reason 1: Due to circuit overload
During use, if the LED flashes every time you turn on other devices, this is probably a signal of circuit overload. When too many devices are used at the same time, the current must be broken down to achieve balance, so the light will become weaker. Overloaded circuits can cause fire, explosion and electric shock.
To solve this problem, you need to separate a device to reduce the circuit load. The long-term solution is to have a professional electrician move to a separate circuit.
Reason 2: Due to damaged or loose wires
The aging or damage of the wire is also the cause of the dimming of the LED. Over time, the wire contact points will corrode, resulting in a decrease in power and brightness.
In addition, the damaged wire is very dangerous to human life, because it can cause fire, explosion, electric shock, etc.
In this case, the only solution is to forcibly replace a brand new wire before causing major problems.
Reason 3: Due to a grid problem
A problem with the grid is also the cause of the dimming of the LEDs. For example, the demand for electricity is abnormally high, or due to the influence of the weather, a transformer failure…has a great impact on the normal operation of the LED. This problem needs the support of electrical technicians to solve.
Reason 4: Lamp life has exceeded
Another important reason for the dimming of LEDs is that the bulb has exceeded the life of the lamp. The LED bulb will not burn like an incandescent lamp during its use, but will only dim. Usually, this dimming is only found at the end of the promised life (if normal operation does not encounter any technical errors during use).
In theory, the average lighting time of LEDs is about 25,000 hours, after which the brightness will be reduced by about 70%. In this case, you should replace the new LED bulb before the bulb life is exceeded. Using LEDs that are too dark is not good for eye health.
#5. LED Strip work Light Remote Not, Working
The LED strip light remote control is easy to use and simple to set up, but some malfunctions may be encountered during use.
If your LED remote control suddenly stops working or starts to flicker, please check its battery first. This may be due to insufficient battery, in this case, try to replace a new battery for your LED strip light remote control.
If replacing the battery does not solve the problem, it may be that the controller is disconnected from the receiver due to a loose connection, or radio interference from the outside…You may need to reset and repair the remote control, as follows:
First of all, for safety, please disconnect the power supply.
Then, you need to unplug the dimming light from the power supply and the LED strip.
Next, plug the power supply and LED back into the receiving unit, and reconnect the power supply.
Simultaneously press and hold “SPEED +” and “SPEED -” on the LED remote control for 3 seconds. The indicator light will flash once, indicating that you have done the correct action.
The remote control and the receiver must be paired, and the light strip must be controlled by the remote control.
#6. LED work Lights Not Turn All The Way Off
If you turned off the switch and your LED still dims a bit before turning it off completely, it could be for some of the following 4 reasons:
Reason 1: Wrong wiring
This is the situation you are most likely to encounter. Under normal circumstances, the hot wire will be connected to the switch, and the wrong connection with the cold wire will cause this phenomenon.
If you use an incandescent lamp, it will not light up, but the led only uses a low-voltage source, so when the switch is turned off, there will be a faint light.
In this case, you only need an electrician to reconnect the standard circuit to overcome.
Reason 2: Excess energy leaks into the bulb
This can happen if the working capacity of the LED bulb in the circuit is lower than the current in the circuit, or the circuit is too old to correct the current correctly.
Traditional incandescent lamps will not light up when only a small amount of current flows, so you will never notice this current, but LEDs are more efficient and only use low-voltage sources. May emit a faint glow before being completely closed
To solve this problem, you can install an LED dimmer in the circuit, or update the wiring at home.
Reason 3: LED bulbs use phosphorus powder
In theory, LED devices can emit light like fluorescent lamps without phosphors. The LEDs emit light due to the LED diodes connected to the circuit board.
However, today’s LED chips are still coated with a layer of blue and white fluorescent powder to create a more real light color and closer to nature. This powder also plays a role in shielding and protecting the chip. lead.
New LEDs such as special-shaped LED aluminum bars are no exception, and SMD LED chips are all coated with fluorescent powder. And widely used in different lighting purposes, such as indoor, outdoor, public lighting…
You have to wait for it to disappear. If you want to repair it, please change to another brand. If you are not satisfied with this phenomenon, please change to other brands that do not use this powder.
Reason 4: Energy from capacitor
A capacitor can provide enough power to make the LED glow for a short time. You can alleviate this effect by using a power supply with a smaller capacitance.
