Why are Incandescent Bulbs Prone to Fire?
Incandescent bulbs are indeed prone to fire, mainly due to their high-temperature working characteristics and improper use environment. So now incandescent bulbs are gradually being replaced by energy-saving light sources such as LED lamps.
Reasons for Incandescent Bulbs to Catch Fire
High heat generation: working temperature is as high as 200℃ or above
We all know that incandescent lamps generate heat and light through the tungsten filament, and their energy conversion efficiency is extremely low.
About 90% of the electrical energy of incandescent lamps is converted into heat energy. This makes the surface temperature of the bulb easily exceed 200℃, and high wattage even reaches more than 300℃.
This high temperature cannot come into contact with other flammable items, such as curtains, paper, plastic products, etc., which can easily cause combustion.
Long-term continuous operation
Incandescent lamps cannot be used for a long time. If they are lit for a long time, especially in the hot summer, the local temperature will continue to rise.
In addition, if there are abnormalities inside the old bulb (such as aging of the tungsten filament and poor contact of the lamp holder), arcing and sparking may also occur, causing electrical fires.
External reasons
If the incandescent bulb is hit or vibrated, it may break. The high-temperature filament will come into contact with the air, causing oxidation reaction and releasing a lot of heat, which may cause a fire.
Lamp holder aging or poor contact
Due to the large operating current of incandescent lamps, poor contact between the lamp holder and the lamp holder will cause local heating.
In addition, the quality of raw materials is poor. If they are not cleaned for a long time or inferior lamps are used, dust accumulation or arcing may also cause local temperature surges.
Close to flammable materials
Many fire accidents occur because the bulb is too close to flammable materials. Therefore, incandescent lamps should not be installed in wardrobes, wooden decorations or ceilings.
If it is installed in a small, poorly ventilated space, heat will accumulate. These may cause the temperature of surrounding materials to continue to rise and eventually catch fire.
Do LED Strip Lights Get Hot?
LED light strips do generate some heat, but it is much less than traditional lighting methods such as incandescent or halogen lamps. LED lights mainly convert electrical energy into light energy, and although they are very efficient, some energy is still dissipated as heat.
But LED light strips also have some high-wattage, high-density LED light strips that are prone to overheating. These light strips are usually recommended to be used with aluminum profiles to help dissipate heat.
Please note that without good heat dissipation measures, the light strip may overheat and shorten its service life. So LED light strips should also be installed in a ventilated place.
What are the Potential Cause of Fire in LED Strip Lights?
LED strip lights are generally known to overheat and not catch fire. However, there are still some factors to be aware of that may affect the life of the LED strip.
Electrical overload
LED strips require a compatible power supply. If the power supply outputs a voltage or current that is outside the design range of the strip, an overload will occur, resulting in overheating, which may eventually cause a fire.
Improper heat management
High-power LED strips generate a certain amount of heat when in operation. If heat dissipation is not considered during installation, especially for high-density LED strips, heat buildup may cause the material to overheat. Therefore, it is important to use LED profiles for heat dissipation.
Poor raw materials
If you use low-quality LED strips or accessories, such as low-quality wires and connectors, you increase the risk of fire. Low-quality materials can overheat, have poor insulation, or cause electrical failures over time, which can cause fires.
Insecure connections
If wires are not securely connected or insulated, a short circuit may occur. A short circuit can generate excessive current and heat, which can cause a fire. Ensuring that all wires are properly connected and well insulated can reduce this risk.
Excessive bending of the light strip
During the installation process, the LED strip lights must not be bent excessively or broken, as this will cause damage to the circuit board or abnormal current. This may cause electrical failure and increase the risk of fire.
Incompatible power supply
Different types of LED light strips require specific power adapters. We need to match compatible LED power supplies with the same voltage and sufficient power. To ensure that the voltage and current output meet the needs of the light strip.
Excessive ambient temperature
If the LED light strip is installed in a high temperature environment and in an unventilated place. It will cause the light strip material to age and the insulation layer to crack, causing a fire. Therefore, when installing the LED light strip, try to avoid installing it in a location that is susceptible to high temperatures.
How to Reduce the Heat of LED Strip Lights?
The heat of LED light strips is small in itself, but we still need to pay attention to its heat. Reducing the heat of LED tape can extend their service life and reduce safety hazards.
Use low-power LED light strips
Choosing low-power or low-wattage LED strips can directly reduce heat generation. The lower the power, the less heat is generated.
Use aluminum profiles to enhance heat dissipation
For high-power LED light strips, materials with good thermal conductivity, such as aluminum profiles, can be used to enhance heat dissipation. Aluminum profiles not only help to fix the LED strip, but also effectively absorb and dissipate the heat generated by the LED light strip to avoid overheating.
Use a dimmer
By adjusting the brightness of the LED light strip, the power output can be reduced, thereby reducing heat generation. When we don’t need it to be so bright, we can use a dimmer to reduce the brightness. This not only reduces energy consumption but also reduces heat generation.
Choose a high-quality LED Tape
High-quality LED strips usually use more efficient chips and heat dissipation designs, which can convert electrical energy into light energy more efficiently and reduce heat generation. Inferior strips usually generate more heat, have a short service life, and are prone to overheating.
Proper power supply matching
It is very important to use a power supply that matches the LED ribbon. Excessive voltage or unstable current can cause the LED strip to overheat, so make sure the electrical specifications of the power supply and the light strip are consistent.
Summary
The heat generated by LED strip lights is still very small, so it will not cause a fire. However, if used improperly, it may catch fire, but the risk is relatively low. As long as you use high-quality LED tape, install them correctly, use a matching power supply, and ensure good heat dissipation, LED strip lights will usually not cause fire.
