Led Light Bulb Heat Sink

Led heat sinks are important as they provide a path for heat to travel from the led to outside elements.

Led light bulb heat sink.

Too much heat will damage led phosphor resulting in lower light output changes in color and or a significant decrease in life expectancy. This is costly because the user will be forced either to reinstall another illuminating system or purchase other led bulbs. Size of the heat sink. Since heat transfer from the led light to the surroundings take place at the heat sink it is advised that the surface area of the heat sink is large.

High power light emitting diodes leds can use 350 milliwatts or more in a single led. Passive or active air then circulates around the heat sink to help cool it. Led maker cree on tuesday is introducing a new consumer bulb that does away with the metal heat sink seen on most led bulbs. The dimmable bulbs come with a lower cost too.

Higher surface area of a heat sink can be achieved by increasing the number of fins in the heat sink or by increasing the overall size of the heat sink as well. Heat sinks used with leds are designed to absorb and disperse excess heat away from the led diode and into the heat sink. If this heat is not removed the leds run at high temperatures which not only lowers their efficiency but also makes the led less reliable thus thermal management of high power leds is a crucial area of. Extracting heat from the device using heat sinks and by operating leds in lower ambient temperatures enables higher light output and longer life of the device.

High power component leds component light emitting diodes led bulbs of various sizes shapes colors and brightness from many brands including cree luxeon nichia more. Such maintenance costs are unnecessary and should be avoided. See how heat sinks protect and cool your leds. 7 97 for a 40 watt and.
