LED Heat sinking guide

9 12 2011

Without LEDs, companies such as Amphenol would be unable to offer the range of connectors and various other electronic components which they currently do.  

An LED is essentially a semiconductor light source. They are used as indicator lamps in a vast range of electronic devices and were first introduced in 1962.

When power LEDs first arrived onto the market, a number of lighting firms rushed out solid-state luminaries only to find them failing in service.

The fundamental problem was heat sinking. Manufacturers were used to filament bulbs that run hot and are cooled by radiation.

That may have been a while ago now. However, the danger of producing unreliable products still exists, particularly as manufacturing companies strive to keep costs down to a minimum.

How do heat sinks work?

The heat generated by complex devices and circuitry can often threaten the reliability of a product and, in some cases, tamper with the ability of a device to function correctly.

With this in mind, heat sinks have become an essential part of modern electronics manufacturing.  Several companies would simply be unable to produce high quality equipment without using this technique.

They are used to reduce and control the temperature of items such as microprocessors through sophisticated heat dissipation techniques. It is at times a complex, but necessary process.

They are basically made up of a small metal structure which includes flat surfaces to ensure good thermal contact with the components that need to be cooled.

A heat sink absorbs and dissipates heat from another object using thermal contact. They are used in a vast range of applications which could include anything that requires efficient and effective protection from heat.
