minus-squareDarkThoughtslinkfedilink11•10 days agoKinda 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.
minus-square@w2tpmf@lemmy.worldlinkfedilink17•10 days agoThe part that emmits the light doesn’t produce heat radiation like a incondecent bulb, but the circuits driving them do.
minus-square@englislanguagelink4•10 days agoThat’s not exactly true. The LED itself also emits heat. In most cases, this is more than the driver.
minus-square@just2look@lemm.eelinkfedilink3•10 days agoLED bulbs for vehicles also usually have at least a heat sink. Some of them even have a fan or other active cooling.
minus-square@IMongoose@lemmy.worldlinkfedilink2•10 days agoI’ve only seen it in enthusiast level flashlights lol.
