Summary

        Technology is all around us. But have you ever thought about how technology works? Where does its power source come from? And what are the implications of its power source? Each device has its own power source but they have one thing in common, most of their power sources produce heat. Devices may work in groups and may cause a phenomenon heat dissipation, which will be discussed in depth in this article.

Heat Dissipation

        Heat is a form of energy. Energy is seen throughout the world. It transfers from one place to another, thus powering the different mechanisms and technology man has built. Heat dissipation is a type of heat transfer. It occurs when a hotter object’s heat is transferred to another object and its surrounding environment (Corrosionpedia.com, 2017). In terms of technology, heat is made when a current flows through a resistor in an electric circuit.

There are 3 types of heat transfer; Convection, Conduction, and Radiation. Convection is the transfer of heat through liquid or gas materials. Conduction is the transfer of heat through solid or liquid materials. Radiation is the transfer of heat through electromagnetic waves. If the heat is excessive it can affect the device itself and cause hazardous situations in its surrounding environment (Renesas.com, 2020).

Myths: Heat Dissipation

        LED displays emit too much heat. The greatest myth about heat dissipation in LEDs is that it can produce too much heat that it affects the whole environment. LED can produce so much heat that it can be a great source of fire hazard.

People have given a lot of thought of how LED works. Generally, most people think that LEDs produce too much heat that makes them feel hot also.

Facts: Heat Dissipation

        LED technology already has an efficient electricity conversion to light. Therefore, LEDs generate less heat. But, there is also an environmental factor that can affect the LED. Generally, LED produces a little amount of heat only, but it depends greatly on where it is installed (Lamphq.com, n.d.).

LEDs are generally cool to touch unless they are IR LEDS. But LED’s production of heat can also be attributed to the efficiency of its semiconductor or design itself (Ledsmagazine.com, 2005). Thus, generally LEDs do not produce too much heat if they are placed in an ideal environment and its design is efficient.
