You will need a heat sink when you use a COB LED in your luminaire. The traditional way of transferring the heat away from the light source is to use a passive aluminum heat sink. In this blog post, I’ll introduce you the new way of cooling: heat pipe.
Traditional heat sinks are based on the fact that aluminum transfers heat away from the light source. The higher the power of the LED is, the more you need aluminum.
This grows the luminaire’s size and makes it more expensive. The bigger size of the luminaire makes logistics costs go up and increases the price for end user even more.
We have a better solution for cooling high power LEDs without the need for noisy fans or heavy heat sinks.
Furukawa Heat Pipe (HYC Series)
Heat pipe technology is traditionally being used in computers and for example in satellites. But now it is available in lighting.
Furukawa HYC Series uses heat pipe technology to transfer the heat and makes heat sinks more efficient in cooling the LED.
Its thermal conductivity is almost 200 times better compared to copper. This also allows the heat sink to be a lot smaller than we are used to.
Smaller heat sink reduces the weight of the luminaire dramatically. This reduces transportation costs as well as the amount of other materials needed.
The Heat Pipe effectively transfers heat from the heat source and as a result makes the cooling faster than ever.
Unlike many Chinese manufacturers, Furukawa uses oxygen-free copper in its Heat Pipes, which means that their lifetime is over 20 years.

Save Money and Environment with our aLED Light Engine
aLED Light Engine (Furukawa Heat Pipe + Citizen COB + optics + aLED Driver)
As a great example, I want to introduce you our own aLED Light engine that uses Furukawa heat pipe with Citizen COB. aLED Light Engine produces over 40 000 lm and weights only 1kg (without driver and optics). And only 3.6kg with optics and driver.
By combining Citizen COB and heat pipe technology, you can build luminaires that:
- Produce a lot of light
- Are light in weight and small in size
- Save environment
- Are completely recyclable
Furukawa Heat Pipes are compatible with Citizen CLU04x and CLU05x COB LEDs.
Download an example of different combinations and datasheets for custom models with screw holes for Citizen COBs.
