Led driver heat dissipation
Did you know?
Nettet\$\begingroup\$ So if the calculation in the answer is correct, and the power dissipation is 12mW when the power is shunted through the FET, and the datasheet claims that the thermal resistance from the junction to mounting base is 4.8K/W, I'm looking at well under 1C of heat from the power dissipated. I assume that's a low figure, but even if it were … NettetIf high efficiency is required – both in battery life or heat dissipation – a constant current switching LED driver is the obvious choice. If simplicity is key, then a linear drive approach may be a good option, either using resistors, or a dedicated LED driver.

Any LED fixture must be designed to keep LEDs cool by reducing heat resistance from the LED to the ambient air. This is done by considering and optimizing all three modes of heat dissipation — conduction, convection, and thermal radiation, in any part of the fixture design. Se mer The temperature at the junction between the LED die and the substrate it is on is referred to as junction temperature. This junction is usually the highest temperature in the device making it … Se mer As a general principle, when LEDs heat up, their efficiency drops.
