Fact or Fiction – Does LED Lights Produce Heat?

It is essential to remember that LED lights consume less energy than traditional light sources and are much more efficient. In addition, LED lights to remain cool when touched unless they are IR LEDs (infrared).  The infrared radiation heats the surroundings and fixture cage of the light sources.

Even though LED lights generate heat, it is generally lower than conventional light sources. Therefore, installing LED cooler lights or high bays is easy as they do not harm the surroundings. On the other hand, incandescent bulbs or halogen lights are outdated technology, and they do generate a significant amount of heat and waste a lot of energy.

Heat is produced inside the LED light due to the inefficiency of the semiconductor processes. But in the case of a power-efficient LED light source, for example, if 100% of power is consumed, only 5% of heat is generated. This is because high-power LED lights to have efficient thermal management systems to release the heat produced. 

Junction temperature – The drive current and the ambient temperature affect the LED fixture’s junction temperature. 

The nature of the lumen output can be in a steady-state or pulsed and LED wattage per unit area of surface, which dissipates heat.  

LED lights are much more relaxed, and most energy produces brightness. As a result, LED waste is considerably less than power consumption. 

Revamping the heat transfer – Use materials with high thermal conductivity to remove the heat from the junction. Unfortunately, the high thermal conductivity material is also made of copper, which is quite expensive.

Heat spreading materials are to be used for high thermal conductivity. Therefore, optimizing the number of LEDs available with the surface area is necessary. 

Environmental temperature – The external weather conditions also affect the internal temperature. An increase in temperature affects the performance of the LED lights. Therefore, you need to check the bulb ratings for their efficiency in the hotter regions.

On the other hand, LED lights are ideal for cold places. LED freezer tubes are perfect for large freezers and refrigerated storage areas. They are non-hazardous to the health and work well in colder temperatures.

Energy-efficient – As we know, LED lights are highly energy-efficient compared to traditional ones. They can operate for 50,000 to 100,000 hours. 

LED lights do not emit much heat as other traditional light sources, and they are also built with sturdy materials for better performance.
