Efficiency tends to decrease with current. It is rarely more efficient to run higher current and PWM than to simply run lower current.
It is, however often easier in terms of circuit design.
- monochromatic 9y agoThat’s interesting, I thought there was an optimal range. Do you have a link with more info?
- Zak 9y agoWell, I can offer an example. This is a test of an LED using a bench power supply. In this test, efficiency drops every time current is increased, without fail. http://budgetlightforum.com/node/51693 http://budgetlightforum.com/node/51693
