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
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
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
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.
