Those are heat radiators (above and below)? Is this thing liquid cooled?
EDIT (just saw the link): So yeah those are heat sinks, but I'm not seeing if they are liquid cooled. Maybe not.
Yes. LEDs on that scale generate a lot of heat. Far less than a normal bulb on the same scale, but the problem is that an LED array is more compact and sensitive, so it retains heat much better, and is more sensitive to it.
Source: I've retrofitted a lot of old ships with more modern LED "bulbs" for their search light.
Kinda crazy to think about considering that LEDs are so efficient that they typically do not produce any significant heat at the use cases we're used to.
The part that emmits the light doesn't produce heat radiation like a incondecent bulb, but the circuits driving them do.
That's not exactly true. The LED itself also emits heat. In most cases, this is more than the driver.
