What can be used as a heat sink?
The most common heat sink materials are aluminium alloys. Aluminium alloy 1050A has one of the higher thermal conductivity values at 229 W/m•K but is mechanically soft. Aluminium alloys 6060 and 6063 are commonly used, with thermal conductivity values of 166 and 201 W/m•K, respectively.
Do LEDs need a heat sink?
With high-power LEDs, it is crucial that you remove heat through efficient thermal management. Without good heat sinking, the junction (internal) temperature of the LED rises, causing the LED characteristics to change for the bad. temperature affects the overall lifetime of the LED as well.
How can you improve heat sink performance?
Highly conductive material reduces heat sink thermal resistance. For similar geometry, copper heat sinks thermal resistance is less than the aluminum heat sink. Therefore heat sink performance can be increased by using a highly conductive material.
Why are my LED lights getting hot?
Due to the way the lighting is laid out and the amount of power generated, both will create heat but the LED will be considerably lower across the entire piece. Yes, new technology LED lighting can and will get hot, but when compared to the lighting of the past, temperatures are much safer.
How are heat sinks used to cool LEDs?
Heat sinks used with LEDs are designed to absorb and disperse excess heat away from the LED diode and into the heat sink. Passive or active air then circulates around the heat sink to help cool it. Too much heat will damage LED phosphor, resulting in lower light output, changes in color and or a significant decrease in life expectancy.
To avoid these problems, the foam heat sink can be soldered to an aluminum or copper carrier plate. This foam-and-plate assembly can then be mounted to a component in a standard fashion. The carrier plate allows sufficient pressure to be applied to the interface material, ensuring low contact resistance.

What kind of material is used to stamp an led heat sink?
Stamping materials are mainly hot and cold rolled steel and steel strip. Compared with die casting led heat sink and forging heat sink, stamping led heatsinks are thin, even, light and strong.
